Manufacturing process of Nylon sheathed wire

Due to the nature of nylon material have different from ordinary plastic, therefore we put forward some unique technical requirements in the extrusion process.
Drying process. Because the nylon material is medium polarity, easy absorption of moisture, according to Nylon sheathed wire material manufacturer, when the nylon material moisture content exceeds 0.3%, cannot squeeze, found in the actual production process, the nylon is expected to be affected with damp be affected with damp, extrusion sheath will blister, such as foam, granular material or damaged. Nylon material itself with vacuum bag vacuum packaging, not broken packages can be directly put into use, but such as transportation damage, sealed or open package are not finished in time, etc., must be dried before use.

So be affected with damp be affected with damp dry nylon material should be done before using. Had better use of pumping air into vacuum state, rotating barrel heating to remove moisture, each drying amount shall not exceed 3/5 dryer volume. Such as the capacity is too big, inside the dryer materials difficult to rotate, cause uneven heating, short time water is difficult to remove all, time is long can make the yellow part material oxidation, unable to meet the requirements of sending out surface. Vacuum degree of vacuum should reach more than 0.05 MPa, or it will be hard to remove moisture, if by steam heating, to control the heating temperature, amount of water vapor temperature appropriate for 80 + / - 50 ℃, the heating temperature is too high the nylon wire material oxidation and become yellow.

Analysis of the minimum installation temperature of flexible cable

Flexible cable temperature and the minimum installation of PVC cable material of low temperature brittle temperature must be inseparable relationship. But how do corresponding relationship, have yet to have authority report. Generally higher than the brittle temperature 5 ℃, the probability of impact test specimen cracking is zero. Theoretically, if the impact of the installation when laying at this moment, less than under the condition of test impact can be construction. But here involves a variety of cable type and construction specification and the testing data of the practice of support.
If you want to truly understand the installation temperature and material laying low temperature brittle temperature relations, is a larger research project, from materials, cables, construction construction (or copy) and so on each link of sampling test, the system to find the critical point of damage, so need a lot of resources and manpower support. Once the figure it out, in turn, to the enterprise is also a great feedback.
If there is really no authoritative data support, to GB/T12706 standard higher than the sheath brittle temperature 20 ℃, laying temperature for a given installation. Though with a difference of 20 ℃ to install laying temperature not so accurate, safe allowance is very big, but definitely not due to the construction temperature cracking quality problems. Differ 15 ℃ installing laying temperature is ok, but must strictly control cable type and construction.

Data cable

With the high-speed development of optical communication technology, the cable network backbone and interoffice trunk line has been widely used optical cable, optical fiber into access network has become an inevitable trend.
But the high cost of optical cable laying, connectors and terminal optical - electrical conversion cost expensive, therefore, for a long time before the packtized popularization, access network user line will continue to give priority to with metal wire. Including all plastic metal cable cable, coaxial cable and data cable. Among them, the data cable is the ideal of broadband access network transmission media, it has low manufacturing cost, simple structure, good scalability, facilitate the advantages of the network upgrades, it is mainly used for building integrated wiring, computer integrated wiring, etc.
Data cable so far, there are two kinds of cable: one is Americas 100Ω cable, mainly for the non-shielded cable; The other is European 150Ω cable, mainly for shielded cable.

International standards generally fall into three categories, four, five, five, six, enhance sexual respectively corresponding to the transmission bandwidth of 16MHZ, 20MHZ, 100MHZ, 100MHZ (support full-duplex transmission), 250MHZ, with seven, eight even now there is no formal definition on the international standard, just of the hype of cabling manufacturer; Levels corresponding to different data cable has the symmetry of the corresponding channel level and, general component is currently CLASS A and CLASS B, CLASS C, CLASS D, CLASS E level, of course and there have been pushed CLASS F grade now. Actually two different areas on different impedance requirement of cable is different based on their structure, generated by the America of 100Ω cable, mainly America so far are not pushing block structure, this is because if the shielding structure can form between the conductor and shield near effect, low frequency parameters, such as change of capacitance and resistance, the other on the shield will have high frequency litter of spin current is generated. But don't block structure, cable, there is no resistance to interference ability and confidentiality is poor, and if you want to do it as more than 300MHZ transmission is difficult, so Europe is implemented block structure, so how to eliminate from the worries of the shield, had to increase through impedance, so Europe is in commonly 150Ω cable. Two structures who good who bad will decide that according to the different application environment, so now the international wiring are generally pay attention to the combination of the two kinds of wiring way. Wide application but it is not shielded structure, and the result of the development of information technology, to follow up the transmission bandwidth requirement, at present more popular is five classes and increase sexual five categories of data cable shielding.

Cable insulation material field in our country

Cable insulation materials, especially high voltage cable insulation materials commonly used in plastics polyethylene, polypropylene, PVC, and other special plastic.
1. PE class cable insulation material
Polyethylenes cable insulation material high insulation resistance, voltage resistance performance is good, especially the dielectric constant and dielectric loss is small, the influence of temperature and frequency is small, and it has good physical and mechanical properties and water resistance, solvent resistance, drug resistance. Related patents on PE class cable insulation materials mainly involved polyethylene cable insulation materials on the flame retardancy, water tree electrical resistance, anti-aging, oxidation and resistance against wear and charred aspect as well as the effect of preparation technology on the improvement.
2. Polypropylene cable insulation material
Polypropylene class cable insulation material density is the smallest and lightest, its heat resistance and mechanical strength is better than that of PE, especially the high frequency characteristics, the modified flame retardant is tasted, can be obtained from foaming.
3. PVC insulated cable material
PVC insulated cable material resistant to high voltage and insulation resistance, flame retardant, oil proof, weather resistance, chemical resistance, corona resistance and water resistance performance, but its dielectric constant and dielectric loss is bigger, cold resistance is poorer, is often used to 1kv and below the wire and cable, semiconduction shielding and all kinds of wire and cable sheath.
4. Other cable material
In addition to the three general plastic formation of the cable insulation materials, fluorine plastic, polystyrene, polyimide and polyamide, polyester and other plastics is also used as cable materials, these materials have a certain feature is also used in some special occasions, such as ptfe, its thermal performance is good, continuous working temperature is 250 ℃, and electrical properties, flame retardancy is better also. But since they don't melt at high temperature, which is unfavorable for processing, and high mechanical strength is not enough, so often as the second polymer and three general plastic copolymerization or blending to improve the properties of the insulated cable materials, through special processing method, a small, separate and high frequency cable insulation materials used for high temperature wire.

In addition, in the field of application for a patent in China is more dispersed, patent quality remains to be improved, there are few enterprises or scientific research institutions formed by a series of interlocking technical patent protection. Anytekabel Co.,Ltd.(www.anytecable.com) the cable has passed CCC, CSA, TUV, CE...Such as certification. At the same time made the patent management system, fully mobilize the employees' innovation enthusiasm.

General Selection Principles of Wire and Cable

Generally pay attention to the choice of wire and cable type, specification (conductor cross section), when you choose wire and cable.
1. The choice of wire and cable model number
Consider the application, installation conditions and security, when you choose wire and cable. For example,
According to different applications, you can select the power cables, overhead insulated cables, control cables, etc.;
Depending on the installation conditions, you can choose the general plastic insulated cables, steel tape armoured cable, steel wire armoured cable, anti-corrosion cable, etc.;
According to the security requirement, you can choose flame-retardant cables, halogen-free flame retardant cable, fire-resistant cable, etc.
2. The choice of wire and cable specifications
Make sure the specifications (conductor cross section) of wire and cable, generally consider the selection condition of fever, voltage loss, economic current density, mechanical strength, etc.
According to experience, because of the large load current of low voltage power line, generally select section according to the heating conditions first, and then calculating the voltage loss and mechanical strength; Low-pressure flare path, because of its higher requirements on voltage level, can select section according to the allows the voltage loss condition first, and then calculating the heating condition and mechanical strength; For high voltage line, select section according to economic current density first, and then calculating the heating conditions and allowed voltage loss; And for high voltage overhead line, should also check its mechanical strength.

The characteristics of flexible cable

High flexible cable is widely used in life and industrial manufacturing, what kind of features makes the high flexible cable so popular?
High flexible cable is on the form is of great importance to PVC outer sheath, the sheath is made of mixed PVC material with high flexible, thus flexibility is excellent. However, because the high flexible cable have this feature, make this cable into the broad industry, mainly used for power transmission and applied to the bending, flexibility requirement high drag chain system.

There are variety of High flexible cable products, can according to the different needs of customers choose to use a different material or different process, expand the use of the cable, the different cable products can meet the demand of different field installation. During the installation process, of course, as a result of the cable of high strength flexibility, not easily broken due to bending of the properties, can greatly reduce the damage rate of staff to the cable, so get the favour of industry installation personnel. Staff need to refer to the instructions on the installation steps, and keep in mind that some daily installation considerations can easily complete the operation, save a lot of time and energy for staff. In addition, high flexible cable products in addition to the characteristics of flexibility, strong resistance to bending, have waterproof and uv protection at the same time, oil resistant, heat resistant, features, so it is suitable to use in the case of poor working conditions.

High flexible cable must be used when produce Drag chain Cable, because the drag chain cable work requires constant bending reciprocating motion, then the cable also need to be relatively active or passive moving, bending motion. Because of the high flexible cable products can ensure normal without load millions of times of movement of the reciprocating bend wire core don't cause fracture, at the same time the characteristics of both high and low temperature resistance makes it can better adapt to the working environment, from all walks of life to so use more widely. In comparison, the other cable to the environment in the process of using or operating various aspects have higher requirements, but this kind of cable is with their own nature advantage, avoid the use of caused many limitations, improve work efficiency for the factory.

There are variety of models of High flexible cables for vendors to choose, and different type side due to the different materials and processes will be focusing on the development of different performance advantages, such as improving insulation, waterproof ability, strengthen the anticorrosive, and so on, but the product has a high standard of resistance to bending damage prevention performance, high quality, easy to operate, the developing of electric power for the factory.

Development and Application of MHYV LSZH flame retardant cable

In the past more than 20 years of practice,  MHYV cable has experienced by innovation from Non flame-retardant to flame retardant, especially in the flame retardant cable flame retardancy test method and decision rule (386-1995, MT MT386-2011) issued and implemented, make the flame retardant properties of the mining cable effectively controled and improved.

But the existing MHYV flame retardant cable once heated combustion, the combustion release a large amount of smoke. Although with IEC 61034 or GB/T 61034-1998 measure the light transmittance of under 10%, but the release of hydrogen chloride (HCl) gas content is large, its content is more than 100 mg/g, even up to 200 ~ 300 mg/g. So thick smoke and toxic gases such as H2S and CO of human respiratory irritation and mischief, and narrow in underground environment, the affected people could not escape from the scene of the fire. According to foreign fire white paper records, this kind of "secondary disasters" casualties of personnel accounts for 70% ~ 80% of the entire fire casualties. In China's coal mine fire accident casualties, the number of people suffering from "secondary disasters" proportion is very big.

Flame retardant or Non flame-retardant cable materials will release a large amount of smoke and CO, HC1 gas when burning, in order to avoid or reduce fire accident "secondary disasters", the international electrotechnical commission (IEC) in 1982 and 1982 successively formulated and revised and IEC60754 IEC60754-1-2, in order to limit when releasing gas content (HC1 content < 5 mg/g, release the corrosive gas combustion of the aqueous solution pH > 4.3, conductivity < 10 TTS/ram). In 1991 and established IEC61034, in order to limit when releasing amount of smoke (smoke light transmittance > 60%). The country's naval engineering standard NES a 718 and a NES 713. The U.S. navy MILS24643 directly the NES a 713 standard to detect when releasing toxic gas content (regulation toxicity index < 5).

All these standards to restrict the cable such as flame retardant or not smoke and poison gas released by the combustion flame retardant materials provides effective and reliable basis, but in this high-risk industry, the mining cable in our country on the control of the LSZH cable is almost blank. When coal with low smoke and low halogen flame retardant burning pollution to the environment is smaller than the burning flame retardant cable, namely coal with flame retardant halogen free cable to reduce or reduce when the burning of "secondary disasters; At the same time performance can meet the requirements of coal mine cable material, is the main direction in the future. Research and application of MHYV low smoke low halogen flame retardant cable is very necessary and important.

The role of wire and cable braiding

Wire and cable is mainly composed of conductive wire core, insulation, sheath layer, three basic structure. The difference between the wire and cable has no strict boundaries, but speaking from a broad meaning, cable structure is complex, it has complex sheath layer, and some only conductor and insulation wire structure is simple, some only weave tu la light armor layer or coating a layer of light soft armor layer. The conductive wire core wire and cable is used for the transmission of current. To reduce power loss and voltage, conducting wire core general selection of high conductivity copper and aluminum. The role of the insulating layer is to prevent the current along the radial leakage, ensure use safety. Therefore require insulating layer has good electrical insulating properties. Heat resistance and mechanical strength.
                      

Outside the insulated wire core or a cable core protection layer called the sheath of the cable. The main function is to protect the insulation sheath. Its main performance is moistureproof, prevent oil, anti-corrosion. Anti aging, sun fire resistant, as well as mechanical protection, but also has the electric and magnetic resistance etc. From the perspective of cable sheath, weaving is many kinds of wire and cable sheath or one of the outer sheath. However, according to the materials used in wire and cable braid braid and different parts in the structure of wire and cable, the role of the braid is obviously different.

cable braiding

The effect of fiber braid
For wire, fiber braid is a form of the light cover. Its main function is to protect the insulation is not affected by or less by all kinds of light, heat, moisture, low temperature, acid and alkali gases such as erosion and external mechanical force damage, to ensure that the wires, such as enhanced sheath is in the middle of the rubber or plastic sheath in cotton yarn, hemp fiber braid, in order to improve the strength of the sheath.
The effect of metallic braid
Metal braided layer are mainly copper, tin plated copper wire braid and steel wire (wire) two woven layer
Is the main purpose of seller, copper wire weaving:
1. Preventing electromagnetic interference shielding effect such as tin plated copper wire braided dedicated cable, wire weaving control cable, etc.
2. Eliminate shield of power cable surface potential, it bound power line and eliminate the induction, such as high voltage cable total shielding.
3. The shielding effect of security protection, in the main core insulation braided copper wire and with core or on the ground a good contact, timely response to the leakage situation, such as mining cable shielding
And social, is the main purpose of steel wire armoured:
L. mechanical protection. Such as Marine power cable CF31 type.
2. Under longitudinal tensile force, such as Marine geology exploration using magnetic measurement cable WC - GC, WCT.
3. The magnetic shielding.
By above can see, the role of braid in wire and cable is obvious, wire and cable prices also will be different, choose to pay attention to the use environment of wire and cable, wire and cable, in order to choose the right wire and cable.

Method to ensure the performance of the cabe Outdoors

The conventional five types of copper cable buried or overhead laying will likely lead to a particular network along the wiring circuit transmission failure, so choose the existing outdoor buried enhanced class cable will bring cheap link.Before deciding the outdoor LAN cable in response to its designed to be fully understood. Over the years, the characteristic of moisture proof protection network has been applied in the communication cable, the aluminum polymeric material overlap the sealing as protection, reduce the water vapor permeability path to prevent water entry.

However an unprotected dry cable will need more than six months to a year due to infiltration of liquefaction, a dry with moisture-proof protection network cable will be completely protected. This design about similar to foil screen LAN cable, cable end connected with simple. So, wiring system designers must consider the application environment, including the parameters of the environment and the influence of the following cable.

If Cable placed on: the eaves. As long as the cable not exposed to direct sunlight or high temperature, standard LAN cable can be used, it is recommended to use pipes. Outside the wall. Avoid direct sunlight metope and artificial damage; In the pipeline. As in the pipeline, pay attention to the damage of the plastic pipe and metal pipe heat conduction; Dangling application/aerial cable. Considering the sag of the cable and stress.The installation of the high flex cable conduit check of dry or wet degree on a regular basis; Underground pipeline. To facilitate future upgrades, cable replacement and phase segregation and surface pressure and the surrounding environment, laying pipe is a good method. But don't hope that the pipeline will stay dry, it will affect the selection of cable types.

Accidents hidden danger of Cable construction is much more in winter

Low medium voltage power cable construction in winter, due to the outdoor temperature are below minus 10 ℃, low temperature of polyvinyl chloride and cross-linked polyethylene insulation and sheath material should suit to present hard brittle features, such as laying accidentally suffers accident knock against, in the process of insulation wire core and copper shield is easily damaged. Even after the cable laying the scene completion test can pass, but later after continuous electricity, cable in the damaged area through the capacitive current eventually, can lead to partial discharge, accelerate the insulation aging, lead to breakdown fault line.

This kind of situation in the low voltage cable performance is not outstanding, performed very well in the medium voltage cable. Sometimes cable factory test without any problems, laying the site due to the limitation of various conditions on cable directly without taking any measures in winter construction, cable laying completed after the scene test everything is normal, but later came a very short time, the power failure, anatomic failure point, appearance without any mechanical damage, but the internal insulation happens serious breakdown and ablation.

Anyte cable

In recent years, some new installation of medium voltage 10kv, 35kv cable fault due to various constraints, not at the scene to cable heating measures, directly around 10 ℃ below zero in winter construction installation on site. The power cable in a short time and white and relatively insulation breakdown fault, by accident, cable production and factory test did not appear abnormal, the scene completion test also smoothly. But electrify malfunction in short time, with no doubt this wire and cable to cable heating measures in winter construction is not relevant.

Introduction of Cable Insulation material

What is the insulation material?
Electrical insulating materials according to their chemical properties of commonly used is different, can be divided into inorganic insulation material and mixed organic insulation materials, insulation materials.Common inorganic insulation material has: mica, asbestos, marble, porcelain, glass, sulfur, etc., mainly used for windings of motors, electrical insulation, switch backplane and insulator, etc.Organic insulating materials are: lac, resin, rubber, cotton, paper, jute, rayon, etc., mostly to cable manufacturing insulating paint, coating insulation of winding wire, etc.Hybrid insulation materials for the above two kinds of material processed into a variety of molding insulation materials, used as the base of the electrical appliances, shell, etc.
The application of insulating material
The role of the insulating material is charged part of the electric cable potential difference in the electrical equipment.Therefore should first insulating material has high insulation resistance and compression strength, and can avoid leakage and breakdown, accident.Second heat resistant performance is better, avoid long-term overheating and aging metamorphism;In addition, still should have good thermal conductivity, tide lightning resistance and high mechanical strength and easy processing, etc.According to the above requirements, the commonly used performance of the insulation dielectric strength, tensile strength, density, coefficient of expansion, etc.

Environmental Friendly LSZH Flame-retardant Cable Material

  We all know that many kinds of harmful gas produced when the wire and cable flaming, such as carbon monoxide, sulfur dioxide, and so on. So the real things hurt the body is the poisonous gases in the fire scenes, among which many of these gases come from household wire and cable. What is the essential difference between Environmental Friendly Halogen-free Cable Material and Ordinary wire & cable material? Compare with ordinary wire & cable material, during the buring, the Environmental Friendly LSZH Flame-retardant Cable Material produce less toxic gas, and produce less smoke, also not easy to be lit.

 
What fields do Environmental protection low smoke zero halogen flame retardant cable material mainly used in?
You know the characteristics of Environmental Friendly LSZH Flame-retardant Cable Materials, obviously the price of the wire and cable of this material must be more expensive than the general material, it is mainly used in some densely populated public places, such as: cinema, and so on. Range can be involved in various types of wire and cable, such as: power cable, telecommunication cable and optical fiber cable, data communication cable, transport system cable, automobile, motorcycle, etc. There are special and strict requirements for wire and cable in these occasions. mong which, the cable insulation sheath material is critical, most of wires and cables we see everyday in some public places are made of low smoke zero halogen flame retardant cable materials.
 

Why is Environmental Friendly low smoke zero halogen flame retardant cable material eco-friendly?
Here we have to introduce a kind of important basic material: polyolefin resin, it is made of inorganic flame retardants fertilizer manufacturing. Due to the basic characteristic of the polyolefin resin and adding a large amount of inorganic flame retardants, gives the cable material flame features such as retardant, low smoke, halogen free, low toxicity and so on. But this kind of wire and cable material is not faultless, the physical and mechanical properties of polyolefin resin, electrical properties, such as performance, now with the improvement of science and technology level, we are improving and perfecting its performance. Changzhou Anytekabel Co.,Ltd., is also in constant research and exploration, believe in the near future we will make the material polyolefin resin much more perfect.

Fire-proof and explosion-proof of Power transformer

Power transformer is the main distribution power system of electric power equipment.Power transformer is mainly is to reduce the high voltage of the grid can be used directly for the 6000 V or 380 voltage, to supply electrical equipment. Such as transformer overload or short circuit inside, insulating material or insulating oil will decompose due to action of high temperature or electric spark, expansion and gasification, the transformer internal pressure has increased dramatically, may cause transformer shell explosion, a large number of insulating oil jet combustion, flow and will further expand the fire danger. In the operation of the fire explosion should pay attention to:
(1) can't overload operation: overload running for a long time, can cause heating coil, make the insulation aging, cause a short-circuit.
(2) often inspection insulation oil: oil should be regularly test, unqualified oil should be replaced in a timely manner, or take other measures.
(3) to prevent the damage of transformer wire and cable core insulation aging, core heat cause insulation aging for a long time.
(4) to prevent because of careless repair damage insulation, if found abrasion damage, will handle in time.
(5) ensure that wire contact is good, poor contact local overheating.
(6) to prevent lightning, transformer will be destroyed due to breakdown of insulation.
(7) short circuit protection: transformer coil short circuit or load, if protection system failure or protection fixed value is too large, could burn down transformer.To install and reliable for this short circuit protection.
(8) to protect good grounding.
(9) ventilation and cooling: if the transformer coil wire is A level of insulation, the insulation is given priority to with paper and cotton yarn.Temperature rise every 8 ℃ half to reduce its insulation life;Transformer normal running temperature below 90 ℃, about 20 years of life;If the temperature to 105 ℃, the life expectancy for 7 years.Transformer operation, to maintain good ventilation and cooling.

Germany daub special fluorescence fluid on cables anti-theft

There is copper exist in cable, wire and cable has become a target for hunting ground in many countries.Telecommunications companies to come up with new ways to do this, Germany, daub on the cable a special fluorescent liquid called "artificial DNA", contains unique code can be used in the lock owner. Deutsche telekom for cable theft losses every year hundreds of thousands of euros.September 30, the company launched a propaganda campaign to show that thief skills: company employee use of remote control helicopters to overhead cable daub the fluorescent liquid, although with the naked eye, coating liquid of cable is not much difference with ordinary cable but under uv light irradiation, daub is special color will be appeared.

Not only that, the liquid unique code as "invisible symbol", visible under a microscope.Through the coding, the true master of the police can find out items.This makes the thief when stealing wire and cable and channeling, must have the courage. Deutsche telekom has begun for the ground cable previously coated with "artificial DNA", is expected to be completed by the end of 2014.The company has not released the security measures. In Germany, railway company enterprise has applied the fluorescent liquid such as security, some people also apply it on the valuables.

Impacts of Mold Structure on Drag Rubber Cable Sheath

With the development of the industrialization, the rubber flexible cable with its stable electric performance, excellent mechanical and physical properties, especially the flexible characteristic, has been the main equipment installation cable in various mobile situations. At present in large open-pit coal mine and metallic ore mining process, there often appears the rubble and sharp objects hit the cable, cable often suffers a lot of drag force in the process of moved along with large mining equipment, so Drag Rubber Cable depends on the special structure design to reduce the effects of external torque to the sheath material, thereby improving the service life of the cable and become the first choice of drag equipment installation.

UTP CAT6

In drag friction occasion, the reduce of cable life often starts from the outer to the inner sheath of wear damage to insulation wire core, so the lifetime of the sheath directly affects the service lifetime of the cable. Drag Rubber Cable adopt make the traditional sheath thickness one divides into two, increase braid structure between the two layers of sheaths to increase the adhesion strength of the inner and outer sheath, braid equipped with a certain elastic force material, to buffer cable sheath reaction in the process of stress, so as to improve the lifetime of the cable.

UL2464 5-24AWG

Once before implementation of sheath can be divided into two times, naturally sheath thickness of each layer is thin, greatly improving process realization difficulty, therefore, the choice of mold for Rubber material during extrusion is especially important. Under normal circumstances, common rubber cable production is implemented through the mold core and mold ratio to provide a larger pressure to fill the cable core, general mold core will choose large Angle, reduce the die sleeve angle, the angle difference of mold core and die set is controled in around 15 ℃, through the Angle difference control extrusion pressure of rubber material, the material compaction under the condition of extrusion in the core surface. The thickness of inner nd outer sheath of drag cabe is thin, production of rubber material is extrusion type, in outer sheath production, rubber material in the core function of extrusion die, when pressure is too large, it is easy to cause mold stucked due to the Accumulation of extrusion of inner sheath.

Reason for longitudinal uneven of wiredrawing extrusion film

Resin plasticizing bad, may be inappropriate given: the heating zone temperature control cable instrument malfunction, resin mixed with different melt index and density of other relevant major resin: extruder factors such as low back pressure.Microscope (40 times) is not melt crystal point, squeeze film dark, opaque, viscous flow instability, caused by melting membrane volatility.Concluded that is the most effective way of plasticizing bad microscope check whether did not melt. The fault handling, you exclude resin is mixed with other resin method in melt index determination, and to determine standard index after comparison.

Then consider to adjust the temperature of the heating area, check the temperature controller.If it is found that the heating zone temperature controller has been heated and reach the given temperature, can reduce the screw rotation speed to achieve the goal of plasticizing good.Appropriate increase extruder back pressure, can increase the screen mesh to achieve, but high back pressure will cause the extruder screw thrust bearing damage.For through the temperature control, raw material, the flow to achieve fusion membrane stability, and production capacity and low, consider to change the screw design, replace the high efficiency screw.
