What is the resistance value of asbestos gasket?
purposeThe utility model is suitable for the pot mouth, the manhole, the hand hole seal, the boiler hand hole, the smoke box belt and the steam ball seal for the reaction kettle.The products are applied in many fields, such as chemical industry (medicine, pesticide, chemical fertilizer, dyestuff, macromolecule, intermediate, etc.), petroleum, electronics, machinery, electric power, environmental protection and so onInternationally, however, asbestos is known to be a carcinogen. In 70s of this century, many countries put forward non asbestos plan, after more than 20 years of efforts, the United States, Japan and Australia and other countries has successfully developed a series of non asbestos gasket material, in 1990 the United States Environmental Protection Agency EPA issued government regulations prohibiting the use of asbestos materials and products, now the advanced countries in the world have been extended to the non asbestos material application field. Ban asbestos material.
Class specificationAsbestos fiber, rubber as the main raw material, and then with rubber compounding agent and filling material, through mixingMixing, hot roll forming, vulcanization and other processes made. Asbestos rubber gasket according to its formula, process performance and use of different, can be divided into ordinary asbestos rubber gasket and oil resistant asbestos rubber gasket. Depending on the temperature and pressure used, it can be divided into low pressure asbestos rubber gasket, medium pressure asbestos rubber gasket and high pressure asbestos rubber gasket. Applicable to water, water vapor, oil, solvents, medium acid and alkali seal, asbestos gasket is mainly used in the middle and low pressure flange connection seal.Low pressure asbestos gasket (G2183): low pressure asbestos gasket is made of a white asbestos fiber, suitable for the majority of low demand, asbestos gasket is mainly used for steam, water, gas, oil seal and non erosive medium.Medium pressure asbestos gasket (G2182): mainly used for steam, hydraulic, gas, oil and non corrosive media seal.High pressure asbestos gasket (G2181): mainly used for steam, hydraulic, gas, oil and non corrosive media seal.Oil resistant asbestos gasket (G2184): mainly used for steam, hydraulic, gas, oil, solvent and non corrosive media seal.Asbestos rubber gasket refers to asbestos and rubber composite gasket products, used in liquid sealed environment. Asbestos rubber gasket manufacturing, in addition to asbestos fiber and rubber, added with agent and filler material, through the processes of mixing, hot roll forming and vulcanization made with good sealing performance.
The withstand voltage is 5.0MpBrief introduction of asbestos gasket:Asbestos pad is made of asbestos fiber and rubber as main raw material, and then with rubber compounding agent and filling material. It is made by mixing, stirring, hot roll forming and vulcanizing. Asbestos fiber gasket according to its formula, process performance and use of different, can be divided into ordinary rubber gasket and oil resistant asbestos rubber gasket. Apply to water, water vapor, oil, solvent, medium acid, alkali seal, used in the middle and low pressure flange connection seal. The most commonly used thickness is 3MM5MM.
