Many people will be curious, how is this rubber O-ring made? It can be used in many places for sealing purposes. So, what is the raw material it uses?
告诉您 ， 橡胶材质分为天然橡胶和合成橡胶两大类，其中天然橡胶的消耗量占 1/3，合成橡胶的消耗量占2/3。 Haisheng Rubber tells you that rubber materials are divided into two categories: natural rubber and synthetic rubber, of which natural rubber consumption accounts for 1/3 and synthetic rubber consumption accounts for 2/3. In addition to natural rubber, synthetic rubber can be divided into general synthetic rubber, semi-general synthetic rubber, special synthetic rubber and special synthetic rubber.
材质的外观形态又分为固态橡胶 (又称干胶)、乳状橡胶(简称乳胶)、液体橡胶和粉末橡胶四大类。 The appearance of the rubber O-ring material is divided into four categories: solid rubber (also known as dry rubber), milky rubber (referred to as latex), liquid rubber and powder rubber. 结构设计的性能和用途，使用在各个工业领域上。 And according to the performance and application of rubber O-ring structure design, it is used in various industrial fields.
材料的物理形态是怎么分类的？ So, how are the physical forms of rubber O-ring materials classified? Rubber can be divided into hard and soft rubber, raw rubber and compound rubber. According to the chemical structure, according to the presence or absence of double bonds in the rubber molecular chain, it is divided into two categories: unsaturated rubber and saturated rubber. The former includes diene and non-diene vulcanized rubber, and the latter includes non-vulcanized rubber and other. (Seal ring) elastomer. (乙丙橡胶、氯化聚乙烯、丙烯酸酯橡胶以及氟橡胶等)，主链含硫的橡胶(聚硫橡胶)，主链含氧的橡胶(聚醚橡胶)、主链含硅的橡胶(硅橡胶)有主链含碳、氧、氮的橡胶(聚氨酯橡胶)等等。 The material of the saturated rubber seal ring is further divided into the main chain containing methylene rubber (ethylene-propylene rubber, chlorinated polyethylene, acrylate rubber, and fluoro rubber, etc.), the main chain containing sulfur rubber (polysulfide rubber), and the main chain Oxygen-containing rubber (polyether rubber) and main chain containing silicon rubber (silicone rubber) include main chain containing carbon, oxygen, nitrogen rubber (polyurethane rubber) and the like. In addition to natural rubbers, they are unsaturated rubbers, as well as synthetic rubbers such as butadiene, butadiene, isoprene, chloroprene, butyronitrile, and butyl. They are the same as methylene type. Rubber can be modified, such as carboxylation, chlorination, chlorosulfonation, etc., as well as pre-crosslinked rubber such as diene benzene.
