Characteristics and application analysis of fluorine rubber seals
seals The term fluorine rubber seals appears more and more frequently in our industrial equipment. what is the reason? With the continuous improvement of my country's industrial manufacturing level, more and more high-temperature and high-pressure environments have led to higher and higher demand for silicone sealing rings, and higher and higher requirements for fluororubber sealing rings. What are the advantages of Viton seals? Can it meet the increasingly high equipment requirements? The first fluororubber sealing ring in English is: fluororubber, referred to as FKM, some natural places are also called FPM, or VITON, it is also called fluororubber elastomer, which contains fluorine on the carbon atoms of the main chain and side chain. atomic polymer. molecules are composed of fluorine atoms, fluorine atoms and carbon atoms. C-F has very high characteristics. At the same time, the fluorine atom has a great adsorption effect, which makes the fluorocarbon molecule in the fluorocarbon molecular chain have a great adsorption effect. C-C With the increase of the fluorination level, the key characteristics are improved and enhanced, and the fluorine atom can improve the C-C main bond. Good shielding is fully guaranteed to C-C chemically inert bonds. Fluorine rubber sealing ring has excellent heat resistance. The most prominent feature of fluorine rubber sealing ring is good heat resistance. It can work for a long time under working conditions of 200 ° C to 250 ° C, and it is not limited to this, at 300 ° C under high temperature , can also work for a short period of time. The tensile strength of fluorine rubber seals is inversely proportional to temperature. Below 150°C, the strength begins to decrease as the temperature increases, and between 150-260°C, as the temperature increases, the rate of decrease will gradually stabilize. Another outstanding feature is the low temperature performance of the fluoroplastic skeleton seal at minus 20°C. In the temperature range of about 5°C, it can still maintain elasticity, but as the temperature decreases, its tensile strength increases, and it becomes hard at low temperatures . When the temperature reaches minus 30°C, the thickness becomes 1.872mm. When the temperature reaches minus 45°C, the thickness becomes 0.631mm directly. When it reaches minus 70°C, the thickness is 0.251mm.
