HRN-GT-1 PTFE Rolling Anti-corrosion Equipment
Steel Substrate Hot-Rolled Liner ETFE (F40) Series
ETFE fluorine plastics, which are made by DuPont Co., Ltd. and Asahi Glass Co., Ltd at present, are mainly applied to anticorrosion liners, has the corrosion resistance of polytetrafluoroethylene which is called Plastic King and a peculiar high property of adhesion to metal, and overcomes the defect that F4 does not adhere to metal. The average linear expansion coefficient of the material is 1.49X10/100 which is approximate to the linear expansion coefficient of carbon steel to ensure that the material can achieve the effect of thermal expansion and contraction synchronized with carbon steel, so that the material become an ideal material compounded with metal. Due to the application of the optimized composite technology to anticorrosive equipment, extremely high negative pressure resistance of anticorrosive equipment is displayed at the same time.
The fluorine plastic and metal composite technology is an achievement of DuPont Co., Ltd. by direct research and application of ETFE (40) and is a new process of rotation sinter molding, and equipment to which the process is applied also is advanced automatically-controlled process equipment. China is in a fledging period in allusion to the application of the technology, and all kinds of new-style anticorrosive chemical equipment with high performance is expected to appear if the technology is further popularized and applied.
