Ultra high molecular weight polyethylene rod

Ultra high molecular weight polyethylene

Product Overview:

Ultra high molecular weight polyethylene (UHMW-PE) board is a high-tech product independently developed by our factory on the basis of learning from foreign advanced technology. It is a thermoplastic engineering plastic with excellent performance. It has various incomparable advantages of ordinary polyethylene and other engineering plastics, and has been listed as a national technical innovation project by the State Economic Commission. The plate has very high impact resistance, very low water absorption, very low friction coefficient, excellent self-lubrication, excellent non-viscosity, excellent corrosion resistance to acid and base. Therefore, it has been widely used in our iron and steel, power, coal, cement, mine and other industries of coal warehouse, silo, gypsum, lime warehouse, cement warehouse, dump truck, mixing cylinder, which solves the long-term problems of bonding, bridging, fast wear, low production efficiency, and is identified as the best engineering plastic to solve the problem of bonding, wear and tear at present by scientific research and design departments. And to the industry to promote vigorously, has achieved significant economic and social benefits. According to the various advantages of the board to develop a variety of uses, size, color, thickness can be customized according to demand, more convenient installation and use.

Features:

1. High impact resistance

Compared with other materials, UHMPE is the best choice because of its excellent impact strength. Figure 1 compares the impact strength of UHMPE with a variety of other commercial resins and engineering plastics.

2. Very low water absorption, excellent non-stickiness

3. Very low friction coefficient, excellent self-lubrication

Uhmpe can be used as an excellent self-lubricating material in sliding applications where the friction coefficient is low. Figure 2 compares the static and dynamic friction coefficients of UHMPE and other thermoplastic engineering plastics. Even in the absence of additives, UHMPE is the most suitable material for sliding applications.

4. Wear resistance

Another outstanding property of UHMPE is its resistance to abrasion. This makes UHMPE ideal for replacing metals in applications where wear resistance is required, while also having the advantage of lightweight. Figure 4 compares the wear resistance of UHMPE to other materials used in high wear applications such as Pipes, bushings, shafts, containers and other equipment. In the application of ultra high molecular weight polyethylene (UHMWPE) technology, it is known that the degree of wear decreases with increasing molecular weight, as shown in Figure 5.

5. Chemical resistance

Ultra high molecular weight polyethylene (UHMPE) has a strong tolerance to a variety of substances. Its material is highly chemically inert and can be used in highly corrosive or erosive environments at moderate temperatures. Even at high temperatures, UHMPE can tolerate a wide range of solvents in addition to strong oxides such as aromatic, halogenated hydrocarbons and nitric acids.

Application Field:

Widely used in steel, electric power, coal, cement, mining and other industries of coal bunker, silo, gypsum warehouse, cement warehouse, dump truck, mixing cylinder, to solve the long-term problems of bonding, bridging, fast wear, low production efficiency, by scientific research and design departments identified as the best engineering plastic to solve the problems of bonding, wear and other problems. And to the industry to promote vigorously, has achieved significant economic and social benefits.

Such as manufacturing mixing machine, silo lining board, etc., good wear resistance, non-stick material, small impact load, energy saving, protect silo body lining, improve mechanical body wear resistance, high temperature resistance, corrosion resistance, protect equipment system parts, reduce maintenance costs, extend the service life of equipment.

The coal bunker is used as the lining board of the coal bunker, it can also be used as the lining board of the granary, and it can also be used as the skateboard of the carriage of various teams. It can solve the material adhesion, shorten the construction period, complete the unloading more quickly, and the function of acid and alkali corrosion resistance can also protect the wall of the warehouse and the inside of the carriage.

The super toughness of the plate can be used as a free anti-collision plate of the door is YYDS; The low temperature resistance and waterproof properties of the plate can be used as fish pond board of fishing machine; It can also be used as a simulation ice plate, without plugging is 1/5 of the cost of the real ice plate, more environmental protection, easy installation, service life in about 20 years. The experience is also very good, can play a variety of ice sports.
