Description
Technical Field

The fluorine-containing lining material has the main function of preventing the metal material inside the pipeline from contacting with the external environment, thereby preventing the problems of oxidation, corrosion, fouling and the like. PTFE is one of the materials with excellent corrosion resistance, and is resistant to almost all chemical media, and is soluble in only a few media such as liquid fluorine and molten alkali metal. PTFE has the disadvantages of large relative molecular weight, poor fluidity, high processing difficulty and the like, and is mainly used as an anti-corrosion lining material in the form of a plate lining. The molding technology of PTFE lining is mainly five types, namely lining three-dimensional rotation molding technology, lining welding molding technology, lining equal-pressure molding technology, lining composite molding technology and lining metal net molding technology. PFA is a copolymer of a small amount of perfluoropropyl perfluorovinyl ether and polytetrafluoroethylene. Melt adhesion is enhanced and melt viscosity is reduced without change in performance compared to polytetrafluoroethylene. The resin can be directly processed into products by adopting a common thermoplastic molding method.
The preparation of PTFE/PFA alloy lining material requires the following steps of selecting raw materials (selecting proper PTFE/PFA material, selecting fluorine resin material with corrosion resistance, abrasion resistance, high temperature resistance and the like according to application scenes); comminuting (comminuting the PTFE/PFA material to a fine powder for subsequent processing); high temperature sintering (after mixing the PTFE/PFA powder with a suitable amount of other components such as graphene, etc., high temperature sintering is performed, typically at 380 degrees celsius, to form a uniform alloy coating from the PTFE/PFA powder).
In actual production, the granularity (granularity) of various materials in the alloy powder is too large, the compactness of the sintered lining material is influenced, if the granularity (granularity) of various materials in the alloy powder is too small, the burning loss rate of the sintered lining material is increased, and meanwhile, the sintered coating is easy to crack, so that the corrosion resistance of the lining material coating is influenced; therefore, the proportion and granularity screening of the raw materials in the alloy powder are particularly important before sintering, and the invention provides a high-efficiency preparation method of a fluorine-containing lining material for high-purity gas-liquid storage equipment so as to solve the problems.
