As a new type of polymer material, PP plastic chain plate has special high wear resistance, tear resistance, high elasticity, high load bearing and other excellent performance. With the continuous promotion and development of food industry enterprises and civilian use, the lines are made. In order to improve the production capacity of the products, various industries have successively adopted PP plastic chain conveyor belts for production operations, in order to replace the traditional conveyor belts.    PP plastic chain conveyor belt not only has the advantages of traditional plastic mesh belt, but also has the characteristics of low density, corrosion resistance, etc., and can better improve the performance of food conveying machinery and equipment, so that it is better. The invention enhances the toughness of the conveying device, and can reduce the impact force and wear resistance of the material on the food conveyor and the drum when producing the transportation material, and has better earthquake resistance and wear resistance.    Compared with other mesh belts, PP plastic chain plates have the characteristics of high production efficiency and low cost, which can save the production cost for food production enterprises, and the cost is only one tenth of the stainless steel mesh belt. PP plastic chain conveyor belt material mesh belt is made of modified polypropylene as raw material, after extrusion, stretching, web forming, surface modification treatment, it is made in the process of short cutting and other process Strength bundled monofilament or mesh organic fiber. PP plastic chain conveyor belt has good resistance to strong acid and alkali, and also has extremely stable chemical properties in terms of weak thermal conductivity.    PP plastic chain plates are widely used, and on the other hand, they have the best insulation performance. Therefore, the PP plastic chain conveyor has undoubtedly become the preferred production line equipment for various food manufacturers with its own excellent performance.

How to identify if there is any miscellaneous material when buying a plastic chain?

    Machinery is used in many places in life, and the effect is great. The machinery is generally driven by chains, and the chain is also diverse. Plastic conveyor chains are also one of them, but people should not be too small, and the effect is really great. However, the quality of plastic chains sold by manufacturers is different, there are good and bad, so people must be careful when buying, many plastic chains will be doped with miscellaneous materials, which will affect the quality. So how do we identify if it is doped with miscellaneous materials when buying plastic chains?    First of all, it depends on whether the surface is flat or not, and the plastic chain made of miscellaneous materials is not flat. This is the obvious feature of the secondary material mixed injection molding.    The second point is to see if the chain lines are smooth and smooth. Generally, the plastic chains made of new materials have the advantages of neat appearance, self-lubricating, etc., and the hand feels lubricated and not rough.    Thirdly, in terms of use, the plastic chain made of miscellaneous materials can not achieve the original performance in application, such as being incapable of wearing and being easily broken, and the chain parts need to be replaced frequently.    As an important part of the conveying equipment, the plastic chain carries an important part of material conveying or mechanical transmission. When purchasing plastic chains, we should pay attention to whether the plastic chain has quality problems. Keep in mind the above methods to identify high-quality plastic chains, so that your inferior products are getting farther and farther away from you.

What is material characteristics of PP, POM and PA

PP POM PA material characteristics 1).POM polyoxymethylene                (POM material conveyor belt sprocket)Typical Applications POM has a very low friction coefficient and good geometric stability and is particularly suitable for gears and bearings. Due to its high temperature resistance, it is also used in pipeline devices (valves, pump housings), lawn equipment, etc.Injection Molding Process Conditions: Drying: If the material is stored in a dry environment, drying is usually not required. Melting temperature: The homopolymer material is 190-230°C; the copolymer material is 190-210°C. Mold temperature: 80 to 105°C. In order to reduce the shrinkage after molding, a higher mold temperature may be selected. Injection pressure: 700 to 1200 bar. Injection speed: Medium or high injection speed. Runners and gates: Any type of gate can be used. If tunnel-shaped gates are used, it is best to use shorter types. Hot-nozzle runners are recommended for homopolymer materials. For the copolymer material, either an internal hot runner or an external hot runner can be used.Chemical and physical properties POM is a tough, elastic material that has excellent creep resistance, geometric stability, and impact resistance even at low temperatures. POM has both homopolymer and copolymer materials. Homopolymer materials have good ductility and fatigue strength but are not easy to process. Copolymer materials have good thermal stability, chemical stability, and ease of processing. Both homopolymer and copolymer materials are crystalline materials and do not absorb moisture easily. The high degree of crystallinity of POM leads to a very high shrinkage, which can be as high as 2% to 3.5%. There are different shrinkage rates for various different reinforced materials.2).PP Polypropylene                 (PP material flexible chain conveyor)Typical range of applications: automotive industry (mainly use of PP with metal additives: fenders, vents, fans, etc.), instruments (dishwasher door liners, dryer vents, washing machine frames and covers, refrigerator door liners Etc.), Consumer goods for daily use (lawn and garden equipment such as lawn mowers and sprinklers, etc.).Injection Molding Process Conditions: Drying: Drying is not required if stored properly. Melting temperature: 220 ~ 275 °C, be careful not to exceed 275 °C. Mold temperature: 40 ~ 80 °C, 50 °C recommended. The degree of crystallization is mainly determined by the mold temperature. Injection pressure: up to 1800 bar. Injection speed: In general, using high-speed injection molding can minimize the internal pressure. If the surface of the product is defective, low-speed injection molding at a higher temperature should be used. Runners and gates: For cold runners, typical runner diameters range from 4 to 7 mm. It is recommended to use round injection ports and runners. All types of gates can be used. Typical gate diameters range from 1 to 1.5 mm, but gates as small as 0.7 mm can also be used. For edge gates, the minimum gate depth should be half the wall thickness; the minimum gate width should be at least twice the wall thickness. PP material can use hot runner system completely.Chemical and Physical Properties PP is a semi-crystalline material. It is harder and has a higher melting point than PE. Since homopolymer PP is very brittle when the temperature of the PP is above 0° C., many commercial PP materials are random copolymers with 1 to 4% ethylene or higher ethylene content clamped segment copolymers. The copolymer PP material has a low heat distortion temperature (100°C), low transparency, low gloss, and low rigidity, but has a stronger impact strength. The strength of PP increases with the ethylene content. The Vicat softening temperature of PP is 150°C. Due to the high degree of crystallinity, this material has very good surface stiffness and scratch resistance. PP does not have the problem of environmental stress cracking. In general, PP is modified by adding glass fibers, metal additives, or thermoplastic rubber. The flow rate of PP has an MFR range of 1 to 40. PP materials with low MFR have better impact resistance but lower strength. For the same MFR material, the copolymer type has higher strength than the homopolymer type. Due to crystallization, PP shrinkage is quite high, typically 1.8 to 2.5%. And the uniformity of the shrinkage direction is much better than that of materials such as PE-HD. Adding 30% of the glass additive can reduce the shrinkage to 0.7%. Homopolymer and copolymer PP materials have excellent resistance to moisture absorption, acid and alkali corrosion, and resistance to dissolution. However, it is not resistant to aromatic hydrocarbons such as benzene solvents, chlorinated hydrocarbon (carbon tetrachloride) solvents, and the like. PP is not as resistant to oxidation as PE at high temperatures. PA nylon(PA material conveyor component side guide connect, star knob)The mechanical properties of PA, such as tensile strength, change with temperature and moisture absorption, so water is a plasticizer for PA. After adding glass fiber, the tensile strength can be increased by about 2 times, and the temperature resistance capability is also improved. Correspondingly, the wear resistance of PA itself is very high, so it can be operated without lubrication. If you want to get special lubrication effect, you can add sulphide to PA.Suitable plastic products: various gears, Plastic Injection Moulded Split Sprocket , turbines, racks, cams, bearings, propellers, drive belts◆PA66 has high fatigue strength and steel property, good heat resistance, low friction coefficient, good wear resistance, but high hygroscopicity and insufficient dimensional stability.Application: Medium-load, wear-resistant force-transmission parts that operate at temperatures ◆ PA6 fatigue strength steel, heat resistance is lower than nylon 66, but good elasticity, better vibration absorption, noise reduction capability. whiteApplication: Light load, medium temperature (80-100) No lubrication or less lubrication◆ PA610 strength.

What is the difference between PC material and PP material?

What is the difference between PC material and PP material?From the outside, the PC is transparent and the PP is translucent. PC is an abbreviation for polycarbonate. Polycarbonate for polycarbonate is English, or PC engineering plastic for short. PC material is actually one of the engineering plastics that we call. As a material widely used worldwide, PC has its own The characteristics and advantages and disadvantages of the PC, PC is a kind of amorphous thermoplastic resin with excellent overall performance, excellent electrical insulation, elongation, dimensional stability and chemical resistance, high strength, heat resistance and cold resistance It also has the advantages of self-extinguishing, flame-retardant, non-toxic, colorable, etc. It can see the shadow of PC plastic in every corner of your life. The features of large-scale industrial production and easy processing also make its price extremely low. Its strength can meet the various needs from the mobile phone to the bulletproof glass. The disadvantage is that the hardness is not enough compared with the metal, which leads to its appearance is easier to scratch, but its strength and toughness are very good, no matter whether it is heavy or general beat. As long as you are not trying to pick it up with stones, it will be long enough. PP is a polypropylene resin. Because the homopolymer PP temperature is very brittle above 0C, many commercial PP materials are random copolymers with 1 to 4% ethylene or clamp copolymers with higher ethylene content. Things.
