Related Introduction
The basic production process of rubber products
With the rapid development of modern industry, especially the chemical industry, there are many types of rubber products, but the production process is basically the same. For products using general solid rubber (raw rubber) as raw materials, its production process mainly includes:
Raw material preparation→plastication→mixing→molding→vulcanization→resting→inspection
The main materials of rubber products are raw rubber, compounding agents, fiber materials and metal materials. Among them, raw rubber is the basic material; compounding agents are auxiliary materials added to improve certain properties of rubber products; fiber materials (cotton, hemp, wool and various man-made fibers, synthetic fibers) and metal materials (steel wire, copper wire) It is used as a skeleton material of rubber products to enhance mechanical strength and limit product deformation.
