Acid and alkali resistance of polytetrafluoroethylene board

Acid and alkali resistance of polytetrafluoroethylene boardThe pH value is 0-14, which can effectively exert product performance in both acidic and alkaline environments. The product performance is not affected, and the temperature resistance and mechanical strength will not be affected, ensuring that the equipment is not corroded.

Polytetrafluoroethylene board 3
(Also known as PTFE board, PTFE board, PTFE board) is divided into two types: molding and turning. Molding board is made by molding PTFE resin at room temperature, and then sintering and cooling it. Polytetrafluoroethylene turning plate is made of polytetrafluoroethylene resin through pressing, sintering, and rotary cutting. Its products have a wide range of applications and excellent comprehensive performance, including high and low temperature resistance (-192 ℃ -260 ℃), corrosion resistance (strong acid, strong alkali, aqua regia, etc.), weather resistance, high insulation, high lubrication, non adhesion, and non toxicity. Polytetrafluoroethylene (abbreviated as Teflon or PTFE, F4), commonly known as the "plastic king", has Chinese trade names such as "Teflon", "Teflon", "Teflon", "Teflon", "Teflon", and "Teflon". It is a polymer compound polymerized from tetrafluoroethylene, with the structural formula of - [- CF2=CF2-] n -, which has excellent chemical stability, corrosion resistance (it is one of the materials with corrosion resistance. Except molten metal sodium and liquid fluorine, it can resist all other chemicals, does not change when boiled in aqua regia, and is widely used in all kinds of products that need acid and alkali resistance and organic solvents), sealing, high lubrication, non viscosity, electrical insulation, good aging resistance, and excellent temperature resistance (it can work at a temperature of+250 ℃ to -180 ℃ for a long time). Polytetrafluoroethylene itself is not toxic to humans, but one of the raw materials used in the production process, perfluorooctanoic acid ammonium (PFOA), is believed to have carcinogenic effects. Temperature range of -20 to 250 ℃ (-4 to+482 ° F), allowing for sudden cooling and heating, or alternating cold and hot operations. The pressure range of -0.1 to 6.4Mpa (full vacuum to 64kgf/cm2) has solved many problems in China's chemical, petroleum, pharmaceutical and other fields. PTFE seals, gaskets, and washers PTFE seals, gaskets, and sealing washers are made by molding suspended polymer PTFE resin. Compared with other plastics, polytetrafluoroethylene has the characteristic of chemical corrosion resistance and has been widely used as a sealing material and filling material.
