ASBESTOS RUBBER SHEET
1. the product description
Asbestos rubber sheet is made up of asbestos, rubber and packing by pressing. According to its formula, process, performance and use different, there are mainly high pressure, low-voltage asbestos rubber sheet in asbestos rubber sheet, and oil resistant asbestos rubber sheet, acid and alkali resistance and other categories.
For pipe flanges, high pressure vessel flange sealing material and all kinds of mechanical junction surface. When using general rushed into various shapes according to the requirement, the size of the gasket.
2. manufacturing material
Manufacture of asbestos materials are chrysotile asbestos rubber sheet, blue asbestos (crocidolite) two kinds.
Chrysotile as part of the serpentine asbestos, its main composition is contains about 13% water of crystallization of magnesium silicate and its heat resistance, good alkali resistance, high tensile strength, acid resistance performance is poorer, most asbestos rubber sheet are produced by it.
Blue asbestos belongs to the class amphibole asbestos, main component is 2.5 ~ 3.5% water of crystallization of silicate, magnesium oxide composition is minimal, iron oxide accounts for about 18 ~ 24%. Blue asbestos heat resistant performance is good, not only and acid resistant performance, so much is used to make acid asbestos rubber sheet.
Asbestos fiber greater effects on the performance of the quality of asbestos rubber sheet, so the requirement of asbestos fiber tensile strength is high, the heat resistant performance is good, there is a certain length, fiber bending, elastic. General high pressure asbestos rubber sheet and more than 400 oil resistant asbestos rubber sheet is 2, 3 levels of asbestos fibers. Due to the use of asbestos rubber sheet limits, more use of ishikawa non-asbestos rubber asbestos board to replace the original.
3. characteristics of purpose
Features: with medium hardness, acid and alkali. In the temperature - between 30 ~ 60 ° C + 20% acid (alkali) in the liquid.
USES: can be coining various kinds of acid and alkali resistant requirements of good gasket sealing performance.
