Shanghai Daoqin Plastics Co., Ltd.

         plastics products surface has good types obvious loss bad methods, its in has material 体 划痕; abrasion material scratch generate abrasion loss;改变 surface property can or gloss surface loss 伤; or 者钝化 material light micro scratch formed “写入效果”. formed this phenomenon is material in pressure force and sliding force or 横(侧) toward force function lower 发生屈服, generate property /脆 property bad from formed 刮痕. in in, surface generate non-uniform light dispersion and “刮痕发化”. improvement property can solution methods is can can decrease small polymer coarse degree and reduce 刮痕 胎肩, make its generate can can less light dispersion and can can small can degree, from to relatively high wear resistance can.

         has plastics already has very good wear resistance, add various wear resistant additives rear, can more add improvement its wear resistance. this additives PTFE, 二硫化钼, 石墨, silicon 利康油, glass fiber (GF), carbon and aromatic polyamide (PA) fiber additives made formed plastics composite/compounding material tool has lubricating property (self lubricating), can reduce combined parts pressure, from improve/increase material wear resistance.

         lower 面就 看看 can improve/increase material wear resistance material.

        1, PTFE （PTFE, iron fluorine 龙）

        PTFE is has resistant add agent in has most low abrasion scratch 系数. in abrasion scratch process in abrasion PTFE separation in parts surface formed lubricated film. PTFE in abrasion scratch force lower has very good lubricated property and wear resistance can, in high negative in, PTFE is most wear resistant additives. this high negative use liquid pressure active ring 封, force gasket. most PTFE content is non crystallization property 含15%PTFE, crystallization property plastics 含20%PTFE.

        2, 二硫化钼

        二硫化钼 另一 Common is ”Moly”, main/primary used for nylon plastics types wear resistant additives. 二硫化钼 function has crystallization agent, use increase nylon crystallization degree, make nylon material generate relatively hard and relatively wear resistant scratch surface. 二硫化钼 for metal has very high hydrophilic and force. 一旦吸附 in metal surface, 二硫化钼 separation 子会填塞 metal surface use micro can 看见 毛 fine 孔, make metal surface more slip. make 二硫化钼 formed is 一 理想 wear resistant additives used for nylon and metal versus abrasion scratch application.

        3, 石墨

        石墨 chemical structure is 一 独特 格子状 structure. 此独特 chemical structure make separation in very small abrasion scratch force upper very easy versus sliding. wear resistant features in has water ring in especially important. features make formed is types wear resistance additives used for very more water in application, water outer housing/shell, 轮叶(impeller) and 关封(Value seals).

        4, poly silicon oxygen 烷

         poly silicon oxygen liquid is types 会移行 wear resistant additives.当 add thermoplastic property plastics in, additives slow to parts surface, formed 一层持续不断 film. poly silicon oxygen has very viscosity scope/range, viscosity 以centistokes amount. poly silicon oxygen viscosity low, formed 流质状且 speed to parts surface provide wear resistant features. poly silicon oxygen viscosity low, in relatively easy 挥发, very fast from parts in 移行消失掉.

        5, glass fiber

         glass fiber is types hard but also loss property high fiber, 因而常 by 错误 认 is plastics in add glass fiber bad plastics wear resistance. glass fiber provide polymer/macromolecule solid machine property combined function, therefore glass fiber can increase thermoplastic property plastics structure property improvement wear resistance. glass fiber provide strong/high can increase plastics resistant property, hot property and hot deformation property, can significantly improvement plastics resistant negative and wear resistant scratch speed degree can force.

        6, carbon fiber

         and glass fiber 情况一素, carbon fiber can large improvement structure overall property, wear resistance and resistant negative and wear resistant scratch speed degree can force. and glass fiber different is carbon fiber is types relatively soft loss property relatively low fiber. carbon fiber 不会刮伤 and its abrasion scratch iron or abrasion scratch surface. thermoplastic property plastics add 入10% above carbon fiber has remove electrical function, can therefore 克服因造 formed electrical issues.

        7, aromatic polyamide (PA) fiber

         aromatic polyamide (PA) fiber is wear resistant additives 之一. glass fiber and carbon fiber, it is most soft and most loss property fiber. features is aromatic polyamide (PA) fiber in wear resistant application main/primary advantages, especially is in combined parts surface for loss property fiber.
