Temperature, time, and pressure are the three major process parameters of rubber product vulcanization. Among them, the vulcanization temperature is the parameter that has the greatest impact on the performance of rubber products, but the rubber vulcanization pressure is also not negligible, so I will introduce to you:
Rubber vulcanization refers to the pressure on the unit area of the rubber compound during the vulcanization process. At the same time, it is also an important factor to ensure the geometric dimensions, structural density, and physical and mechanical properties of rubber parts. Defects play an important role in meeting the requirements of product sealing and airtightness.
The selection of rubber vulcanization pressure needs to consider the formula of the rubber compound; the plasticity of the rubber compound; the structural form of the forming mold (molding, injection pressure, injection, etc.); the type of vulcanization equipment (flat vulcanizer, injection pressure vulcanizer, injection) Vulcanizing machine, vacuum vulcanizing machine, etc .; these five factors are the structural characteristics of products.
In addition to the above effects, rubber vulcanization pressure is extremely important in improving the compactness, resistance to winding and physical and mechanical properties of rubber products. Rubber vulcanization pressure can also provide power for the mold filling flow of the rubber, so that the rubber It can fill the entire mold cavity within a specified time, which has a great effect.
However, it should be noted that the rubber vulcanization pressure should be maintained properly, too large or too small will have some adverse effects. Qingdao Xinyefei Machinery Co., Ltd. stated that excessive rubber vulcanization pressure will damage the molds, equipment, and consume electricity. What is important is that it will affect the performance of the products. Too little pressure will have a direct impact on the geometric dimensions and physical and mechanical properties of the product, so the rubber vulcanization pressure should be maintained properly.
