GUOMAT rubber vulcanization process analysis

2, thermal stability: vulcanization improves the thermal stability of the rubber, reducing the impact of the external temperature difference on the performance of the air spring. For example, when the unvulcanized natural rubber is lower than 10 °C, the long-term storage will produce crystal hardening; the temperature exceeds At 70 ° C, the plasticity increases remarkably; when it exceeds 100 ° C, it is in a viscous flow state; at 200 ° C, decomposition begins to occur. However, after vulcanization, the high elastic temperature range is expanded, and the brittleness temperature can be lowered to below -20 to -40 ° C, and the plastic flow state of the raw rubber does not occur. Therefore, vulcanization greatly increases the temperature of use of natural rubber. In fact, the actual use environment of the air spring factory is far more complicated than the laboratory environment. High Matt constantly accumulates customer feedback data, actively cooperates with customers' needs, and customizes the air spring to win the praise of users.

3. Density and gas permeability: Within a certain range of vulcanization time, as the crosslink density increases, the rubber density increases, while the gas permeability decreases with the increase of crosslink density. This is very important for the use of air springs. The lower the gas permeability, the less gas is spilled during use. The higher the stability of the air spring, the lower the frequency of pumping.
