Emerging Chemical polyethylene liner | Liner wear anti-adhesive car

Emerging Chemical polyethylene liner wear anti-adhesive car plate lined chute liner mixer bulldozer bulldozing plate lining excavator bucket lined with cars lined tractor tipper Coulter combine sliding plate lined concrete tank lining (discharge port liner) polyethylene liner performance cars: 1, high wear resistance: in all current engineering plastics in the best wear resistance of UHMW-PE, the most striking. The higher molecular weight of the material, the more wear-resistant, even more than many metal materials (such as carbon steel, stainless steel, bronze, etc.). For example UHMW-PE pipe, in highly corrosive conditions and high wear life is 4-6 times of steel, but also improve the transmission efficiency of 20%. Fully demonstrated the "energy saving, environmental protection, economic and efficient" superiority. 2, corrosion resistance: in lye from corrosion, 75% concentrated sulfuric acid, 20% nitric acid stable performance, its water, liquid detergent and very stable. 3, low coefficient of friction: static friction coefficient of 0.07, good self-lubrication, is an ideal bearings, bushings, slider, lining material. UHMW-PE as a selection device friction member, in addition to improving wear life, you can also receive energy-saving effect. 4. Impact resistance: the impact resistance ranks first in plastic, both strong external impact or internal pressure fluctuations make it difficult to crack. The impact strength of nylon 66 is 10 times, 20 times polyvinyl chloride, polytetrafluoroethylene 8 times; especially at low temperatures, but the impact strength of the highest value, its flexibility performance delivery system to provide a very safe and reliable protection. 5, anti-aging: stable performance, good aging resistance, ground, can be buried underground, 50 years without aging. Measured according to ASTM method (load 4.6㎏ / cm2), heat distortion temperature of 85 ℃, temperature up to 90 ℃, under special circumstances, to allow use at higher temperatures. UHMW-PE is an excellent toughness of the material, its low temperature performance is very good at - at 269 ℃ low temperature, still has some ductility, but no signs of embrittlement. However, larger coefficient of linear expansion, thermal conductivity is poor, so when designing products, should be given full attention. 6, electrical properties: a large volume resistivity, breakdown voltage of 50KV / mm, a dielectric constant of 2.3. In a wide temperature and frequency range suitable for use as a structural material in electrical engineering. 7, non-toxic health: UHMW-PE tasteless, non-toxic, odorless, non-corrosive in itself, with physical inertia and physiological adaptation. The US Food and Drug Administration (FDA) and the US Department of Agriculture (USDA) to allow it to be used in contact with food and medicine applications. Polyethylene liner automotive applications: can replace carbon steel, stainless steel, bronze and other materials used in the textile, paper, food machinery, transportation, medical, coal, chemical and other sectors. Such as the textile industry on technical shuttle, a playing shuttle rods, gears, couplings, sweeping flower stem, buffer block, eccentric, rod bushings, swing consequences of impact-resistant wear parts. Do cover plate on the paper industry, wiper blade, compaction components, connectors, mechanical drive shaft seal, side guide wheel, scrapers, filters and the like; do powdery material transport industry hoppers, silos, chutes lining.
