The hardness is 75-90, and the product bent at 180 degrees is free from white traces. The light aging impact strength retention rate for 500 hours is 100%, and the bending strength is 65-70MPa. The product is bacteria resistant and ultraviolet irradiation resistant, and can be widely produced and continuously place existing materials.
Description
Technical field
The application belongs to plastic material field, relates in particular to the wear-resisting switch of a kind of polyoxymethylene.
Background technology
POM is a kind of tough and tensile resilient material, even if still have at low temperatures good creep resistance characteristic, geometrical stability and impact property.The existing homopolymer material of POM also has copolymer material.Homopolymer material has good ductility/strength, fatigue resistance, but is not easy to processing.Copolymer material has good thermostability, chemical stability and is easy to processing.No matter homopolymer material or copolymer material are all crystalline material and be difficult for absorbing moisture.The high crystallization degree of POM causes it to have quite high shrinking percentage, can be up to 2% ~ 3.5%.For various enhancement type material, there is different shrinking percentages; Polyoxymethylene (pom) is a kind of engineering plastics of excellent property, has abroad the title of " taking steel by force ", " polyoxymethylene goods 2 supersteels ".Pom has hardness, intensity and the rigidity of metalloid, all has good self lubricity, good resistance to fatigue within the scope of very wide temperature and humidity, and springiness, and it also has good chemical-resistant in addition.Pom is with the cost lower than other many engineering plastics, substituting some traditionally by market that metal captured, as instead of zinc, brass, aluminium and steel are made many parts, since coming out, the fields such as that pom has been widely used in is electric, mechanical, instrument, daily light industry, automobile, building materials, agricultural.In the application of a lot of frontiers, as aspects such as medical skill, sports equipment, pom also shows good growing trend.
Derlin is strong and hard well allusion quotation has thermoplastic (property) plastics of good fatigability and chi ten stability, its electricity has low frictional coefficient and good thermotolerance to think that Derlin is similar to nylon, but its resistance to fatigue, creep resistant, hardness and water tolerance are better than nylon.Along with the development of social city, technicalization, hommization, design a kind of rub resistance, frictional coefficient is low, aging-resistant polyoxymethylene switch fabric, to meet the need of market, is very important.
Summary of the invention
