The application of ultra-high molecular weight polyethylene

by:SanTong     2021-02-05
Because of ultra-high molecular weight polyethylene has many excellent characteristics, it is on the high performance fiber market, including from offshore oil field of mooring rope to high performance lightweight composite materials are showing great advantage, in the modern war and areas such as aviation, aerospace, maritime defense equipment plays a vital role.     1. Ultra-high molecular weight polyethylene can make coal, limestone, cement, mineral powder, salt, corn, and so on powdery file trailers, silo and chute liner, because it has excellent self-lubrication, not sticky, can make the powder of the above documents for storage and transportation facilities without adhesion, ensuring stable sponsor.     2. Ultra-high molecular weight polyethylene used for sand flow such as liquid sponsor pipelines, compared with other pipe outstanding performance at: the 18 times higher compared with the bamboo tubes full, interest rates fall to 1/25, compared with nylon tube taking 3 times, interest rates fall to 1/8. Barrier in the sponsor, the tube is smaller than non-metallic pipe 25%, greatly improving the frequency of sponsor.     3. In chute, bucket and ore compartment lining and so on, using traditional nonmetallic file, in cold damp weather, items will thaw on non-metallic, and plank will never adopt molecular weight polyethylene (uhmwpe), which greatly reduced the unloading cost. In the bulk transport of dump on land with a high molecular polyethylene sheet, symmetry discharge time by the original 16 ~ 20 h to 8 h.     4. In terms of national defense military equipment, because of its impact resistance performance is good, is greater than the energy absorption, the military can be made into protective cloth, helmets and bulletproof material, such as helicopters, tanks and ships armor plate, radar protection shell cover, the missile shield, body armor, extra clothes, shields, parachute, etc.     5. In aerospace engineering, due to its light weight, high strength and good shock resistance, suitable for all kinds of aircraft wing tip structure, the structure of the spacecraft and buoy aircraft, etc. Also can be used as the reduction of the space shuttle landing plane and a suspension of lifting rope, instead of traditional steel rope and synthetic fibre ropes, its exceptionally rapid development speed.     6. In the field of civil, made of rope, rope, sails and fishing gear used in ocean engineering, under the weight of the fracture length is 8 times that of steel rope, is 2 times of aramid fiber. The rope is used for super tanker, Marine platform, such as a beacon of anchor rope, solved the previous use of steel cable corrosion, polyester and nylon rope of corrosion, such as hydrolysis, ultraviolet degradation caused the decrease of strength of the cable and rupture, often need to be replaced.     7. In industrial applications, can be used for pressure container, conveyor belt, filter materials, automobile cushion plate, etc. ; Architecture can be used as a wall, diaphragm structure, use it as a reinforced cement composite material can improve the toughness of cement, improve the shock resistance. Due to its excellent abrasion resistance, impact resistance, it is widely used in machinery manufacturing industry, can produce all kinds of gear, CAM, impeller, roller, pulley, bearings, bearings, bushings, cutting shaft, gasket, seal, flexible coupling, screws and other mechanical parts.     8. In sports goods has been made on the helmet, skis, sail round plates, rods, the racket and cycling, gliding plate, ultra-low weight aircraft parts, etc. , its performance is superior to the traditional materials.     9. In medicine, used to graft and plastic plates materials, medical suture, and other fields, it has good biocompatibility and durability, and has high stability, will not cause allergic, have for clinical application. Also used for medical gloves and other health measures, etc.
