How is the rubber extracted from rubber joints?
 
Rubber joints are so close to our life. Hydroelectric power plants, thermal power plants, urban water supply and drainage industries all use rubber joints. The most important thing in rubber joints is the rubber balls. Later, we use the excellent performance of rubber raw materials and other chemical components to get various models of rubber joints we use, which are acid and alkali resistant, high temperature resistant, weather resistant, low temperature resistant, etc.
 
The extraction of rubber is also the original starting point of the whole process. Rubber is extracted from the latex of rubber trees, rubber grasses and other plants. There are 2,000 species of plants in the world from which gum similar to natural rubber can be obtained, and in 500 of them the gum is different. Yes, but long-term experiments have concluded that the only really useful one is the rubber tree from Brazil. After processing, it has a variety of properties such as elasticity, insulation, and resistance to permeation, making it an ideal material.
 
Rubber, as a polymer, is polymerized with various monomers to obtain the synthetic rubber we need, and the rubber products produced are used in various industries and in life. The rubber materials used in rubber joints are both natural rubber and synthetic rubber, never using cheap recycled rubber available in the market. The most important part of the rubber joints we produce is the rubber ball. Using the properties of excellent rubber raw materials plus other chemical components at a later stage to get the various types of rubber joints we use, acid and alkali resistant, high temperature resistant, weather resistant, low temperature resistant, etc.
