High elastic polymer compound. Divided into natural rubber and synthetic rubber two kinds. Natural rubber is made by extracting gum from rubber trees, rubber grasses and other plants, while synthetic rubber is made by polymerization of various monomers. Rubber products are widely used in all aspects of industry or life.
Rubber Seal is a kind of universal basic component in sealing device, which plays a very important role in the contradiction of leakage and sealing. Solve the problem of leakage and sealing in the process of human conquering nature. It has been an important way to promote technological progress, prevent and reduce environmental pollution. Rubber seal is a kind of rubber product widely used in sealing technology. Because rubber has precious elastic polymer material, a wide temperature range, giving small stress in different media will produce large deformation, which can provide contact pressure, compensate the leakage gap, and achieve the purpose of sealing.
Rubber seal is made of metal rubber, which is a kind of homogeneous elastic porous material. It not only has the elasticity of rubber, but also has the excellent characteristics of metal. It can work at - 150 ~ 800 ℃. At the same time, it can also bear pressure, and has the double functions of bearing pressure and sealing in a certain range. Its uses mainly include the following:
1. Glass fiber reinforced plastic pipe; glass fiber reinforced plastic sand pipe; glass fiber reinforced plastic pipe jacking; cable protection pipe; flue gas desulfurization pipe; coal mine gas drainage pipe; power plant desulfurization and dust removal pipe;
2. Sealing of municipal water supply and drainage pipes;
3. All kinds of process pipeline sealing (petroleum, chemical industry, metallurgy, papermaking, sewage, desalination, food brewing and beverage processing, medicine, etc.);
4. Sealing of sewage collection and transmission pipeline and reclaimed water pipeline;
5. Sealing of drinking water transmission main pipe and distribution pipe;
6. Sealing of water injection pipe in oil field.
