High temperature rapid vulcanization system

With the automation and linkage of rubber manufacturing, high-temperature rapid vulcanization systems are widely used, such as injection vulcanization and cable vulcanization. The so-called high-temperature vulcanization refers to vulcanization performed at 180 to 240 ° C. Generally, for every 10 ° C increase in vulcanization temperature, the vulcanization time can be shortened by about half, and the production efficiency is greatly improved. However, an increase in the vulcanization temperature causes a decrease in the physical and mechanical properties of the vulcanizate, which is related to a decrease in the crosslink density at high temperature vulcanization. When the temperature is higher than 160 °C, the crosslink density decreases most obviously. Therefore, the higher the vulcanization temperature, the better. The high vulcanization temperature should be considered comprehensively.
