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。将其内衬于泵、阀内壁，既克服了氟塑料材料强度低的缺点，又解决了泵、阀主体材料抗腐蚀性能差、成本高的不足。另外，氟塑料除了具有优异的化学稳定性外，其防污、防粘性好、动静摩擦系数值极小且相近，减摩润滑性能良好，将其做为阀门启、闭件的密封副，可降低密封面间磨擦力，减小阀门操作扭矩，提高产品使用寿命，其使用范围还可扩展到食品、医药工业。其内衬材料除PTFE（F4）、FEP（F46）、PVDF（F2）外，又扩展到聚烯烃类的PE、PP及PVC范围，以满足各种不同工况参数的需要。介质浓度%温度，25200硫酸SULFURIC ACID0-100发烟硫酸FUMING SULFURIC ACID硝酸NITRIC ACID0-100发烟硫酸FUMING SULFURIC ACID盐酸HYDROCHLORIC ACID磷酸PHOSPHORIC ACID氢氟酸HYDROFLUORIC ACID氢溴酸HYDROBROMIC ACID氢碘酸HYDRIODIC ACID氢氰酸HYDROGEN CYANIDE亚硝酸NITROUS ACID亚硝酸NITROUS ACID氯酸CHLORIC ACID次氯酸HYPOCHLOROUS ACID高氯酸PERCHLORIC ACID四磷酸N-TETRADECYLPHOSPHONIC ACID碳酸CARBONIC ACID铬酸CHROMIC ACID硅酸SILICIC ACID硼酸BORIC ACID砷酸ARSENIC ACID硒酸SELENIC ACID氟硅酸HEXAFLUOROSILICIC ACID氟硼酸FLUOROBORIC ACID氯磺酸CHLOROSULFONIC ACID王水AQUA REGIA混酸MIXED ACID介质浓度%温度，200 氢氧化钠SODIUM HYDROXIDE氢氧化钾POTASSIUM HYDROXIDE氢氧化铵AMMONIUM HYDROXIDE氢氧化镁MAGNESIUM HYDROXIDE氢氧化钙CALCIUM HYDROXIDE氢氧化铝ALUMINIUM HYDROXIDE氢氧化钡BARIUM HYDROXIDE氢氧化铁IRON TRIHYDROXIDE氢氧化亚铁FERROUS HYDROXIDE介质浓度%温度，200 甲酸FORMIC ACID醋酸（乙酸）ETHYLIC ACID（ACETIC ACID）0-冰醋酸ETHYLIC ACID丙酸PROPIONIC ACID丙烯酸ACRYLIC ACID丙烯酸酐ACRYLIC ANHYDRIDE（沸点）甲基丙烯酸METHACRYLIC ACID（沸点）丁酸BUTYRIC ACID辛酸OCTANOIC ACID月桂酸LAURIC ACID软脂酸PALMITIC ACID硬脂酸STEARIC ACID油酸OIL ACID亚油酸LINOLEIC ACID松香酸ABIETIC ACID脂肪酸FATTY ACID氯醋酸CHLOROACETIC ACID乳酸LACTIC ACID草酸（乙二酸）OXALIC ACID富马酸FUMARIC ACID柠檬酸CITRIC ACID介质浓度%温度，200 甲酸FORMIC ACID醋酸（乙酸）ETHYLIC ACID（ACETIC ACID）0-冰醋酸ETHYLIC ACID丙酸PROPIONIC ACID丙烯酸ACRYLIC ACID丙烯酸酐ACRYLIC ANHYDRIDE（沸点）甲基丙烯酸METHACRYLIC ACID（沸点）丁酸BUTYRIC ACID辛酸OCTANOIC ACID月桂酸LAURIC ACID软脂酸PALMITIC ACID硬脂酸STEARIC ACID油酸OIL ACID亚油酸LINOLEIC ACID松香酸ABIETIC ACID脂肪酸FATTY ACID氯醋酸CHLOROACETIC ACID乳酸LACTIC ACID草酸（乙二酸）OXALIC ACID富马酸
