Application Of Ultra High Molecular Weight Polyethylene Liner

Jun 05, 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. such as the textile industry in the technology shuttle, shuttle rod, gear, coupling, sweep rod, buffer block, eccentric block, rod bushing, swing consequences and other impact-resistant wear parts.

Paper industry to do box cover plate, scraper, compaction parts, joints, transmission machinery sealing shaft rod, partial guide wheel, scraper, filter and so on. The lining of the hopper, silo and chute of the powder material is made in the transportation industry. Can do high modulus fiber, the manufacture of bulletproof clothing, aircraft seats, sea, fishing ropes and so on.

 

Application range and polyamide, PTFE similar, wear resistance more than carbon steel, do gears, bearings, shafts, star wheels, valves, pumps, rails, sealing fillers, equipment lining, sliding plate, artificial joints, fiber for bulletproof clothing, ropes and so on. Ultra high Molecular weight polyethylene has many excellent properties, but few people know its existence because of its excellent engineering plastics, which is mainly due to the lack of research on the melt characteristics of ultra-high molecular weight polyethylene, and the processing method is basically still stuck in the backward suppression of a sintering process. It has a long history of use in the textile industry.

 

The components on the loom need to have impact resistance, shock cracking, self-lubricating and muffler, making textile machinery The earliest application of ultra-high molecular weight polyethylene. Since the first production of ultra-high molecular weight polyethylene components in the 1950s, more than 200 kinds of ultra-high molecular weight polyethylene textile components have been introduced. The toughness of ultra-high molecular weight polyethylene is fully displayed on the skin knot of the fast loom: the effect of the leather knot is to stop and tap the shuttle, so that it moves back and forth through the loom. Shuttle is usually 3-5 kg heavy steel products, at the highest speed, the number of shocks can be up to 200 times/rain.

 

Before the use of ultra-high molecular weight polyethylene. Under the same conditions, the use of ultra-high molecular weight polyethylene leather knot can accept 5 million ~1 5 million impact at present, the average number of ultra-high molecular weight polyethylene parts used in each textile machine abroad has 3O parts. Such as shuttle, shuttle rod, gear, connector, sweep rod, buffer block, eccentric block, rod bushing, swing rear beam and other impact-resistant wear parts.
