What are the Functions of Rubber Gasket?
December 06,2022
The rubber gasket has the properties of oil resistance, acid and alkali resistance, cold and heat resistance, aging resistance, etc. It can be directly cut into sealing gaskets of various shapes and is widely used in medicine, electronics, the chemical industry, anti-static, flame retardant, food, and other industries.
The rubber gasket refers to the thin rubber products that play a sealing role between the two static surfaces of the metal flange or other connection parts. It can be made by molding or vulcanized rubber. It can be widely used in various mechanical equipment such as gaskets, seals, buffers, etc.
Classification of rubber gaskets
Formally, common rubber gaskets include rubber flat gaskets, rubber O-ring gaskets, plastic flat gaskets, PTFE-wrapped gaskets, asbestos rubber gaskets, metal flat gaskets, metal profiled gaskets, metal sheathed gaskets, corrugated gasket, spiral wound gasket, etc.
- Rubber flat gasket: It is easy to deform and does not take much effort to compress, but its pressure resistance and temperature resistance are poor. It is only used in places with low pressure and low temperature. Natural rubber has certain acid and alkali resistance, and the use temperature should not exceed 60 ℃. Neoprene rubber can also withstand certain acids and alkalis, and the operating temperature is 80 ℃. Buna-N rubber is oil resistant and can be used up to 80 ℃. Fluorine rubber has good corrosion resistance and temperature resistance and can be used in 150 ℃ medium.
- Rubber sealing gasket: the section shape is round, which has a certain self-tightening effect. The sealing effect is better than that of the flat gasket, and the compression force is smaller.
From the material point of view, the main products of rubber gaskets include silicone gaskets, nitrile rubber gaskets, fluorine rubber gaskets, and other rubber gaskets. It can be directly cut into sealing gaskets of various shapes. And it is widely used in medicine, electronics, the chemical industry, anti-static, flame retardant, food, and other industries.
