fluorine plastic (PTFE) commonly known as the "king of plastic", by DUPONT CO. and LTD America, developed the first came in 1949 1938, industrial production, from the perspective of industrial application has been 50 years of history, and the true it will be widely used in the valve industry in time is not long. The company introduced in 1985, the Chinese Academy of Sciences in Shanghai China patent materials, fluorine plastic factory, is the earliest use of fluorine plastic corrosion pump manufacturing, valve, pipe and other products of the enterprise.
fluorine plastic corrosion resistant valve is PTFE resin (or sections processed) by compression (or embedded) the outer surface of the inner wall of the valve pressure parts or fittings placed in steel or iron method, using its strong anti-corrosive medium on the unique performance made all kinds of pumps, valves, piping.
in corrosion resistant materials, PTFE material with excellent performance can not be compared, in addition to molten alkali metal fluoride and aromatics, in various concentrations of hydrochloric acid, sulfuric acid, nitric acid, aqua regia, organic acid, strong oxidizing agent, concentrated and dilute acid was alternately, the Sui reaction of acid and alkali alternate and a variety of organic solvents, the PTFE lined on the inner wall of pump and valve, which overcomes the disadvantages of low strength vinyl PTFE, has successfully solved the limitation of the scope of application of chemical pump in corrosive medium conveying. Is conveying all kinds of strong corrosion resistance chemical medium ideal.
