Teflon
The trade name of PTFE is "Teflon" (Teflon, Flu on), simple PTFE or F4, commonly known as the king of plastics. It is one of the most corrosion-resistant materials in the world today. It is used to manufacture liquid gas pipelines, heat exchangers, etc. Ideal sealing material for connection of content equipment.
Tetrafluoroethylene [PTFE, F4] is one of the best corrosion-resistant materials in the world today, so it is known as the "Plastic King". It can be used in any kind of chemical medium for a long time, and its production has solved many problems in my country's chemical, petroleum, pharmaceutical and other fields. Teflon seals, gaskets, gaskets. Polytetrafluoroethylene seals, gaskets, and gaskets are made of suspension polymerized polytetrafluoroethylene resin. Compared with other plastics, PTFE has the characteristics of excellent chemical resistance and temperature resistance. It has been widely used as a sealing material and filling material.Our company can now provideFluoroplastic centrifugal pump
carbon fiber
Carbon fiber is a fibrous carbon material with a carbon content of more than 90%. The C/C composite material composed of it and resin is one of the most corrosion-resistant materials.
Carbon fiber (CF for short) is a new type of fiber material with high strength and high modulus fiber with a carbon content of more than 95%. It is a microcrystalline graphite material obtained by piling up organic fibers such as flake graphite microcrystals along the axial direction of the fiber, after carbonization and graphitization. Carbon fiber is "flexible on the outside and rigid on the inside". Its mass is lighter than that of metal aluminum, but its strength is higher than that of steel. It also has the characteristics of corrosion resistance and high modulus. It is an important material for national defense, military and civilian use. It not only has the inherent characteristics of carbon materials, but also has the soft and processability of textile fibers. It is a new generation of reinforcing fibers.
Carbon fiber has many excellent properties. Carbon fiber has high axial strength and modulus, low density, high specific performance, no creep, ultra-high temperature resistance in a non-oxidizing environment, good fatigue resistance, specific heat and electrical conductivity between non-metallic and Among metals, the coefficient of thermal expansion is small and anisotropic, the corrosion resistance is good, and the X-ray permeability is good. Good electrical and thermal conductivity, good electromagnetic shielding, etc. Compared with the traditional glass fiber, the Young's modulus of carbon fiber is more than 3 times; compared with Kevlar fiber, the Young's modulus is about 2 times, and it does not swell or swell in organic solvents, acids and alkalis. Outstanding corrosion resistance.
Copper oxide
Copper oxide is currently the most corrosion-resistant material. Sweden has always been a world leader in the field of nuclear waste disposal. Now its technicians are using a new container made of copper oxide to store nuclear waste, which can guarantee safe storage for 100,000 years.
Copper oxide (CuO) is a black oxide of copper, slightly amphiphilic and slightly hygroscopic. The relative molecular mass is 79.545, the density is 6.3~6.9 g/cm3, and the melting point is 1326℃. It is insoluble in water and ethanol, soluble in acid, ammonium chloride and potassium cyanide solution. It dissolves slowly in ammonia solution and can react with strong alkali. Copper oxide is mainly used to make rayon, ceramics, glaze and enamel, batteries, petroleum desulfurizers, insecticides, and also for hydrogen production, catalysts, green glass, etc.
