阻燃PPS 1140A64日本宝理

阻燃性PPS 1140A64日本宝理---The disadvantages of PPS are: high price,low price in high temperature resistant plastics, but much higherthan general engineering plastics; poor toughness, brittle;unstable viscosity. Pure PPS is seldom used alone because of itsbrittleness, and most of the PPS used are modified ones.Specifically: 40% Glass Fiber Reinforced PPS (R-4), inorganicfilled PPS (R-8), Carbon Fiber Reinforced PPS (G-6), etc.

PPS的存在的不足有：价钱太高，在耐高温塑料中归属于底价，但比通用性橡胶制品高很多；延展性差，性脆；中黏度不稳定。纯PPS因特性脆而非常少独立应用，运用的PPS多见其改特性种类。实际有：40%玻纤提高PPS（R-4），无机物添充PPS（R-8），碳纤维材料提高PPS（G-6）等。

喷涂成型工艺：
聚苯硫醚的喷涂以静电粉末喷涂为主，喷涂前需将金属工件进行除油、喷沙、化学处理，以提高工件与聚苯硫醚的粘附力，在370～400℃下预热处理10～20min，用喷将PPS粉末喷到工件表面，待流平、固化后得到平整而有光泽的涂层。

Spray forming process:

PPS is mainly sprayed by electrostatic powder. Before spraying,the metal workpiece should be degreased, sandblasted and chemicallytreated to improve the adhesion between the workpiece and PPS.After preheating at 370-400 ℃ for 10-20min, PPS powder is sprayedon the surface of the workpiece. After leveling and curing, asmooth and glossy coating is obtained.
