O-ring is a kind of interface for the O-type rubber ring, small shape, but the role is very big, often used in hydraulic and pneumatic transmission system. Many people will probably think that this seal is a pure rubber ring, no material on the difference. In fact, there are many kinds of rubber used to make O-rings. Therefore, O-rings are also divided into a large variety of materials. Today, Mingzhen Xiaobian will introduce O-rings in the article. I hope you can share the characteristics of the material and various materials.
O-ring is actually a kind of rubber ring, named after it has a circular cross section. The function of O-ring is sealing to prevent the leakage of liquid or gas. It is mainly used in mechanical parts. Due to different application environments, the requirements for O-ring are different. Therefore, O-ring is derived from many different types, and people can choose different materials according to different use environments. There are many kinds of materials for O-ring seals. Below, let's share some of the commonly used materials!
nitrile rubber sealing ring:
Nitrile rubber sealing ring has excellent corrosion resistance, tear resistance and compression deformation resistance, ozone resistance, sunlight resistance, weather resistance is good. It is suitable for washing machinery, automobile engine system and refrigeration system using new environmental protection refrigerant R134a. Is currently the most widely used, the lowest cost of rubber seals. However, it has poor tensile resistance and does not have oil resistance. Therefore, the silicone rubber sealing ring is mostly used in some products, such as microwave ovens, water heaters, electric irons, etc.
fluorine rubber sealing ring:
High temperature resistance is better than silicone rubber, has excellent weather resistance, ozone resistance and chemical resistance, cold resistance is poor. For most oils and solvents have resistance, especially acids, aliphatic hydrocarbons, aromatic hydrocarbons and animal and vegetable oils. Suitable for sealing needs of diesel engines, fuel systems and chemical plants. It is not recommended for ketones, low molecular weight esters and mixtures containing nitrate. The general use temperature range is -20~250 ℃.
fluorine silicone rubber sealing ring:
Its performance has the advantages of fluorine rubber and silicone rubber, oil resistance, solvent resistance, fuel oil resistance and high and low temperature resistance are good. It can resist the erosion of oxygen-containing compounds, aromatic hydrocarbon-containing solvents and chlorine-containing solvents. Generally used for aviation, aerospace and military purposes. Exposure to ketones and brake fluid is not recommended.
natural rubber sealing ring:
Natural rubber sealing ring has good wear resistance, elasticity, tensile strength and elongation. However, it is easy to age in the air, becomes sticky when exposed to heat, is easy to expand and dissolve in mineral oil or gasoline, and is resistant to alkali but not strong acid. It is suitable for use in automobile brake oil, ethanol and other liquids with hydroxide ions.
The above is the material of several commonly used o-rings shared by Xiaobian!
