Understanding Rubber Vulcanization
Vulcanization is a chemical process that enhances the properties of rubber. It involves cross-linking polymer chains using a vulcanizing agent, typically sulfur. This creates a stronger, more resilient material resistant to temperature fluctuations and degradation. The process is critical for producing various rubber goods, from tires to medical devices, as seen in the product catalog of hongjusilicone.com. The degree of vulcanization directly impacts the final product’s hardness and elasticity.
Types of Vulcanization Processes
Several methods exist for vulcanizing rubber. These include press vulcanization, continuous vulcanization, and microwave vulcanization. Press vulcanization, commonly used in manufacturing, employs heat and pressure within a mold. This method is widely adopted by manufacturers of rubber products, as showcased on en.qdxiangjie.com. Continuous vulcanization is a high-volume process ideal for long, continuous rubber products like conveyor belts. Microwave vulcanization offers faster curing times and more precise temperature control.
