Corrosion Resistance (F46) of Fluorine Plastic Table 氟塑料(F46)耐腐蚀性能表 Fluorine Plastic (PTFE-F4, FEP-F46), commonly known as the king of plastic was first developed and published by DUPONT CO.,LTD in American in 1938. It has been industrial produced for 50 years since 1949. Fluorine plastic lined corrosion resistant pump valves is made by FEP(F46) or section bar that molding or embedded then put it the inside and outside on the pressure-containing of steel or iron pump valves, using the uniqueness of strong corrosion resistant of chemical producing pumps, valves, pipe etc. Fluorine plastic with unparalleled performance in corrosion-resistant material renders inert reaction in various concentrations of hydrochloric acid, sulfuric acid, nitric acid, aqua regia, organic acid, strong oxidant, alternation of concentrated acid and diluted acid, alternation of acid-bases and various organic solvents, except in alkali metals, fluorine and aromatic hydrocarbons. Fluorine Plastic lined in pumps and valves not only overcomes the low strength but also solves the poor corrosion resistance and high cost of fluorine plastic. Fluorine plastic has excellent chemical stability, working well in anti-fouling, anti-sticking, extremely small and similar static friction coefficient, anti-friction lubrication, which is used as the valve set and close seal reducing friction between the sealing surface and operating torque of the valve, improving service life of products. The scope of application can be extended to food, medicine and industry. In addition to its lining material PTFE (F4), FEP (F46), PVDF (F2), and also extended PE, PP and PVC range of Polyolefin to fit different operating conditions. 氟塑料（聚四氟乙烯-F4，聚全氟乙丙烯-F46）俗称“塑料王”，是由美国DUPONT CO.,LTD于是1938年首先研制问世，1949年进行工业化生产，从工业应用角度已有50年历史。　　氟塑料衬里耐腐泵阀是将聚全氟乙丙烯树脂[F46]或型材经加工采用模压或镶嵌方法置于钢质或铁质的泵阀承压件的内壁或管件的内外表面，利用其在抗强腐蚀介质方面的独特性能制做成各类泵、阀、管道等产品。　　在抗腐蚀材料中，氟塑料具有无可比拟的优异性能，除了熔融碱金属、元素氟及芳香烃类有腐蚀现象外，在其余各种浓度的盐酸、硫酸、硝酸、王水、有机酸、强氧化剂、浓、稀酸交替，酸、碱交替和各种有机溶剂中均呈 惰性反应
