pu wear-resistant hose, plastic wear-resisting vacuum tube, anti-aging corrosion resistant vacuum hose to transport air, dust, sand, wood chips or wood, natural rubber has the superior properties, and wide range of USES, the applicable scope wide: from applicable industry, can also be used to do all kinds of automobile, motorcycle, engineering machinery, mining machinery, ships, machine tools, train, high pressure cleaning machinery, petrochemical equipment, hydraulic equipment, pneumatic equipment, cable sheath, instruments and meters, food equipment, medical equipment and other products use hose, this series of vacuum tube in agricultural irrigation, industrial and mining, oil depot, pumping sand, sand blasting, food, medicine and indoor gas emissions, powder, dust absorption, and other fields has a wide range of USES.
pu wear-resistant hose, plastic wear-resisting vacuum tube, anti-aging corrosion resistant vacuum hose materials are mainly polyurethane, polyurethane is Chinese name, its molecular structure containing & ndash; NHCOO— Unit of polymer, the element is composed of isocyanate and hydroxyl reaction, reaction is as follows: & ndash; N = C = O + HOˉ→ — NH - COOˉ。 This series of vacuum tube its physical and chemical properties between rubber and plastic, has excellent properties. Check wear-resisting property is one of the main indexes of Taber abrasion value, its Taber abrasion value is 0. 35 - 0. 5 mg, is the smallest plastic, it is other plastic can't of, this is he can keep good abrasion resistance.
pu wear-resistant hose, plastic wear-resisting vacuum tube, anti-aging corrosion of the vacuum hose wear-resisting degree between rubber and plastic products, rubber elasticity and high temperature resistance, but also has some plastic oil corrosion resistance, wear resistance, ageing resistance, resistance to low temperature, such as tensile performance. According to the relevant departments of the test, the series of vacuum tube of oil resistant performance is 15 ~ 20 natural rubber; Wear resistance is a natural rubber 30 ~ 50; Aging resistance is 3 ~ 5 natural rubber; Can work between - 40 ℃ ~ 120 ℃. In addition to better improve its wear resistance properties, add lubricants in processing, in order to better reduce the friction between the molecules, the use of lubricant make reduce the friction between the molecules get bigger, so as to further improve the wear-resisting degree.
