Rubber is also a polymerRubber factory production process
Natural rubber: tapping → processing (filtration, solidification, drying, forming) → natural rubber
It is just mentioned that natural rubber is also a polymer. Natural rubber is a polymer called polyisoprene, which can be obtained from rubber trees. After the bark of the rubber tree (the main tree species is the trefoil tree) is cut, the rubber tree will secrete a large amount of rubber sap, which is the raw material of natural rubber, latex. This step is called tapping.
After the latex is transported to the processing plant, the rubber factory is mixed with raw materials, centrifuged with ammonia (if it is to be made into a liquid latex), or solidified, air-dried, and tableted to form a variety of natural rubber. Unless it is the latex industry (liquid latex is used), most of the natural rubber will be transported to other factories for other applications after solidification, tableting (for easy transportation).
There is also a procedure in the production of natural rubber from rubber factories. "Vulcanization" is a procedure to improve the performance of natural rubber. The unvulcanized natural rubber is not easy to form, is softened by heat, becomes hard and brittle when it is cold, and is easily aged and loses elasticity. Vulcanization can "crosslink" the linear long chain of the rubber, and the original linear structure becomes a three-dimensional three-dimensional network structure, thereby enhancing the elasticity and strength of the rubber.
