Glass lined reactor as you may know, but you know it gasket glass lining reaction pot. Today to introduce you to the glass lined reactor types and properties of pan gasket, as follows:
1, winding type gasket, with steel strip (Galvanized 08 steel, galvanized steel, 0Cr18Ni9Ti, etc.) and asbestos board or rubber asbestos sheet winding between the 15, strip to spot welding or positioning ring to be fixed. This gasket is flexible, can play a multi-channel sealing effect, can be used for high temperature and pressure (the use of temperature up to 600 degrees Celsius, pressure up to 6.4MPa) of the occasion. In the temperature and pressure fluctuations, the gasket can still work steadily. Sealing surface of the waterline of wound gasket type seal has no effect, and repeated use after the demolition of the impact of gasket should be to not waterline belt of the sealing surface is appropriate.
2, sheet metal gasket, rubber gasket from the general rubber plate, acid proof rubber plate (30 ~ +60 degrees Celsius), oil resistant rubber plate (30 ~ + 100 degrees C oil, gasoline, transformer oil), heat resistant rubber plate (30 ~ + 100 degrees pressure steam, hot air) and other four kinds, the gasket is suitable for temperature and pressure of stainless steel reactor.
3, asbestos rubber gasket sheet by the numbers and types of asbestos fiber and adhesive made of asbestos rubber plate with different performance, by the use of the performance can be divided into: six of high, middle and low pressure, oil resistance, acid resistance, alkali resistance, is the most widely used, use temperatures up to 450 DEG C, or even individual up to 700 DEG C, pressure is less than 6Mpa stainless steel reactor, but temperature and pressure can not be also too high.
4, metal gasket, metal gasket with high strength, good heat resistance characteristics, according to the corrosive medium to choose the right material. Commonly used metal gasket material is iron, steel, alloy steel, copper, aluminum, nickel, silver, etc.. Aluminum pad is widely used, the temperature can reach 400 degrees Celsius purity of 99.8% of the aluminum pad can be used for 98% of the concentration of nitric acid seal. The gasket can be made into the form of a flat pad, a tooth shaped pad, an oval pad, an eight star pad and a lens pad. The main disadvantage of this type of gasket is the pre tightening force, the processing of complex, high cost, so the general is mainly used for high pressure stainless steel reactor.
5, asbestos board and plastic plate gasket made of acid asbestos asbestos board for concentrated inorganic acids (nitric acid, sulfuric acid, hydrochloric acid) strong oxidizing salt solution (sulfur dioxide, nitrogen oxide, chlorine, etc.) have better sealing effect. In recent years in acid and alkali and other corrosive medium in a variety of plastic (PVC, polyethylene, PTFE and so on) has been widely used, polyvinyl chloride used in dilute nitric acid of 60 degrees Celsius, PTFE can be used in any concentration of nitric acid in 200.
6, wrapped gasket asbestos gasket resistance to high temperature, strong corrosion resistance, good elasticity, but the strength is low, so the outside of asbestos in accordance with the medium properties of black iron sheet, galvanized iron sheet, copper, aluminum, lead, stainless steel, etc., and sometimes the need for corrosion resistance of PTFE plastic material. Effect of temperature of iron pad 500 DEG C, the use of pressure can reach 44MPa (gauge). Due to the wide application range of temperature and pressure of the iron package, the manufacture is simple, and it is widely used in the stainless steel reaction vessel. When mounting, the graphite powder is coated on the gasket, which is not only convenient for disassembly, but also can improve the sealing effect.
Warm tip: glass lining reaction pot shim safety products, selection of excellent quality of the goods, in order to ensure the safety of glass lining reaction pot, stable and efficient operation.
In the previous：A fine glass lined equipment should have what conditions?1, winding type gasket, with steel strip (Galvanized 08 steel, galvanized steel, 0Cr18Ni9Ti, etc.) and asbestos board or rubber asbestos sheet winding between the 15, strip to spot welding or positioning ring to be fixed. This gasket is flexible, can play a multi-channel sealing effect, can be used for high temperature and pressure (the use of temperature up to 600 degrees Celsius, pressure up to 6.4MPa) of the occasion.

Sealing surface of the waterline of wound gasket type seal has no effect, and repeated use after the demolition of the impact of gasket should be to not waterline belt of the sealing surface is appropriate.
