Ultra high molecular polyethylene (uhmpe) sheet is a new type of wear-resistant sheet with wide application
Ultra high molecular polyethylene (uhmpe) sheet is a kind of high wear-resistant sheet, which can be designed to fit the installation and application under various environmental conditions. For example, the application of installing hoppers and chutes in underground coal mines with difficult operating conditions and feeding funnels in metallurgical industry can solve the problem of sticking and blocking materials in the conveying process and realize safe, efficient and normal production.
Application: can be applied to mining, coal preparation plant. Metallurgical industry, power plant, shipbuilding and other departments of conveying liquid, solid and solid-liquid mixture of funnel, leakage tank, frame, the chute of scraper conveyor, grid plate, flotation machine, plate, ship's cargo compartment lining board, large slider, harvesters, skip car lining, abrasion and corrosion of applications such as value with excellent quality and reasonable price.
High polymer polyethylene plate wear resistance, impact resistance, friction coefficient is increasing, these properties play what role
1. Improve wear resistance. In the present plastic, its wear resistance is good, even many metal materials (such as carbon steel, stainless steel, bronze, etc.) have a regular grinding than it. As the molecular weight of polyethylene increases, the material becomes more durable.
2. High impact resistance. The impact strength of uhmwpe is related to its molecular weight. When the molecular weight is less than 2 million, the impact strength increases with the increase of molecular weight and reaches a peak value of about 2 million. At this point, the impact strength will decrease when the molecular weight increases again. This is because the molecular chain hinders its photoluminescence, so there are large amorphous regions in the large molecules that can absorb larger impact energy. Ultra high molecular weight polyethylene (uhmwpe), even at -40oc low temperature, still has a very good impact resistance, even at liquid-gas -269oc, still can maintain a good impact resistance, this low temperature characteristics, so that the application of ultra high molecular weight polyethylene (uhmwpe) extends to the field of low temperature engineering.
3. Low friction coefficient. Uhmwpe has good wear resistance, low friction coefficient and good self-lubricity, so it is an ideal material for bearing bushing, sliding block and lining. Using uhmwpe as the friction part of the equipment can also get the effect of knot.
The properties of uhmpe sheet are widely used
Ultra high molecular weight polyethylene (UHMWPE) sheet has the properties of other sheets, which are used in various industries. In each industry to play their own characteristics, so that our construction can be good and fast,
Good wear resistance, good low temperature impact resistance, self-lubricity, water resistance, chemical resistance, heat resistance better than general PE.
UHMWPE can replace carbon steel, stainless steel, bronze and other materials for textile, paper, food machinery, transport, coal mining, chemical industry and other sectors. Such as the textile industry on the technology shuttle, shuttle rod, gear, coupling, sweeping rod, buffer block, eccentric block, shaft sleeve, swing consequences of impact wear parts. On the paper industry to do box cover plate, wiper board, pressing parts, joints, drive machinery seal shaft, deflector, scraper, filter, etc.; Lining of hopper, silo and chute made of powdery material in transportation industry.
UHMWPE (ultra high molecular weight polyethylene sheet) can be made into various mechanical parts, including food machinery gear, worm gear, worm, bearing. Do pump, valve, baffle plate, filter plate in chemical industry. Medically, it can also be used for heart valves, short surgical parts, artificial joints and birth control implants. Sports for skating floor, ground, snowboard, motor sledge parts. UHMWPE can be used as high modulus fiber, making body armor, aircraft seats, Marine, fishing ropes and so on.
Mechanical properties higher than the general high density polyethylene. With impact resistance, stress cracking resistance, creep, low friction coefficient, self-lubricity, chemical corrosion resistance, noise damping, etc.
Service temperature 100 ~ 110℃. Good cold resistance, can be used at -269℃. With a density of 0.935g/cm3 and a molecular weight of 2 million, the product has a tensile strength at break of 40MPa, a elongation at break of 350%, a bending elastic modulus of 600MPa, and continuous notch impact of cantilever beam. Abrasion (MPC method)20mm. In the presence of ziegler catalysts, ethylene or ethylene is polymerized with n-olefin. Application range and polyamide, polytetrafluoroethylene similar, wear resistance more than carbon steel, do gear, bearing, bearing bush, star wheel, valve, pump, guide rail, seal packing, equipment lining, sliding plate, artificial joint, fiber for bulletproof vest, rope, etc.
The performance characteristics of Pe plate application field because UHMW- Pe plate has good wear resistance, impact resistance, self-lubricity, so it is very suitable for the production of various wear-resistant mechanical parts, such as support wheel, shaft sleeve, nozzle, stirring blade, the application range is wide. General application areas: transportation machinery: sliding block guide rail, conveyor belt, transmission device, a fixed plate food machinery: the star wheel, filling machine bearings, gears, roll paper machinery: suction box cover plate, partial idler pulley, scraper, bearing, nozzle, filter, wear, ball watts textile machinery: painting machine, shock absorber baffle, connectors, picking stick construction machinery: bulldozer, dump car in on sheet metal materials, chemical machinery, valve body, pump body, gaskets, filters, gear, screw nut, sealing ring, shaft sleeve, port machinery, Marine parts, bridge crane with edge roller, wear-resistant parts such as general machinery: All kinds of gears, bearings, bushings, hinges, sliding plate, clutch, guide body, roller, roller, fasteners, lifting platform sliding piece dyeing adornment: dyeing machine bearings, scraper, sliding plate, gasket, seal, stenter guide PE sheet plate ultra-high molecular weight polyethylene PE black PE sheet white PE sheet green PE board, PE board ultra-high molecular weight polyethylene plate ultra-high molecular weight polyethylene
