Use of ultra high molecular weight polyethylene liner

Aug 16, 2019

Ultra-high molecular weight polyethylene liner can replace carbon steel, stainless steel, bronze and other materials used in textile, paper, food machinery, transportation, medical, coal, chemical and other sectors. For example, textile shuttles, shuttle rods, gears, Impact-resistant wear parts such as couplings, sweeping bars, buffer blocks, eccentric blocks, rod bushings, and swinging effects. In the paper industry, it is used as a cover plate, a wiper plate, a pressure-tight part, a joint, a sealing shaft of a transmission machine, a deflector wheel, a scraper, a filter, and the like.


 

 

The lining of the hopper, silo and chute of the powder material in the transportation industry. It can be used as a high modulus fiber to make body armor, aircraft seats, shipping, fishing ropes, etc. The application range is similar to that of polyamide and PTFE. The wear resistance exceeds that of carbon steel. It is used for gears, bearings, bushings, star wheels, valves, pumps, guide rails, sealing packings, equipment linings, sliding plates, artificial joints, etc. Used as bulletproof vests, ropes, etc.

 

Ultra-high molecular weight polyethylene has many excellent properties. However, such excellent engineering plastics are rarely known for its existence. This is mainly due to the insufficient research on the melt characteristics of ultra-high molecular weight polyethylene, and the processing method basically stays. In the backward suppression of a sintering process. It has the longest history of use in the textile industry. The parts on the loom need to have impact resistance, shatter resistance, self-lubricating and sound-absorbing properties, making the textile machinery the earliest application field of ultra-high molecular weight polyethylene.

 

After the production of the first ultra-high molecular weight polyethylene parts in the 1950s, more than 200 textile parts of ultra-high molecular weight polyethylene were introduced. The toughness of ultra-high molecular weight polyethylene is fully demonstrated on the skin of high-speed looms: the role of the knot is to stop and strike the shuttle, moving it back and forth across the loom. The shuttle is usually a steel product weighing 3-5 kg. At the highest speed, the number of impacts can reach 200 times/rain. Before using ultra high molecular weight polyethylene.

 

Under the same conditions, ultra-high molecular weight polyethylene skin knots can accept 5 million to 15 million impacts. At present, there are an average of 3O ultra-high molecular weight polyethylene parts used in each textile machine abroad. Impact-resistant wear parts such as shuttles, shuttle sticks, gears, couplings, sweeping bars, buffer blocks, eccentric blocks, rod bushings, swinging rear beams, etc.
