ETFE (F40) from 1: 1 and ethylene tetrafluoroethylene copolymer from. ETFE (F-40) fluorine plastic and metal composite technology is DuPont Direct Application ETFE (F-40) the outcome of this technology as a new three-dimensional rotation sintering process, and the implementation of new technology equipment is advanced automatic control technology equipment. Application of the new technology, will make a variety of new, anti-corrosion, high-performance equipment continue to come out. Application of ETFE (F-40) fluorine plastic is still in its infancy, pending further step application. ETFE (F-40) from the fluorine plastic is currently DuPont and Asahi Glass Company. At present, the material is mainly used in anti-corrosion lining, because the material has a corrosion-resistant properties of Teflon, but there are strong metal adhesion characteristics peculiar to overcome the Teflon non-metal adhesion defects, together with its average linear expansion coefficient of 1.49 * 10-4 / ℃, linear expansion coefficient close to steel to make ETFE (F-40) to become the ideal composite materials and metal, to this optimization of complex technology in anti-corrosion equipment on, it shows that the technology to produce equipment with very good resistance to negative characteristics. |
