1. The coefficient of linear expansion indicates the degree of expansion or contraction of the material. It refers to the expansion rate of PTFE plastic products when the temperature rises 1 ℃ under a certain pressure, expressed as the linear expansion coefficient relative to the unit length. The coefficient is one of the important indexes to understand the change degree of the size of PTFE
Application: Teflon is widely used in mechanical, electronic, automotive, aerospace, chemical, computer, electric heating, military, communications and other important scientific and technological fields. Such as micro transformer.
Because the content of metal ions in PFA tube is very low, it can maintain strong strength and burst pressure at high temperature. It is because of its excellent electrical properties that PTFE tubes become suitable materials for electronic and electrical fields. Polytetrafluoroethylene pipe is mainly used for electrical insulation sheath, chemical transportation, heat exchanger, chemical heavy corrosion protection, etc.
The trigger mode of thyristor is divided into electric trigger and optical trigger. Abb and Siemens are representatives respectively. Converter valve is the core equipment of DC transmission project. By connecting the three-phase AC voltage to the DC terminal in turn, the desired DC voltage can b
Enjoys the reputation of the king of the "plastic" fluorine plastic, with its excellent performance in modern industry, construction, transportation, aerospace, and plays an irreplaceable important role of high technology, is one of the pillar industry modernization.
Tetrafluoroethylene products consists of ptfe resin, with mold after cold pressing sintering, it has excellent corrosion resistance, good self-lubrication and adhesion. So the products resistance to almost all chemical medium, and with wear-resisting, withstand voltage, low coefficient of friction properties. It is widely used in petroleum, chemical industry, metallurgy machinery, traffic in many fields such as medicine, food, electric power.
