What happens to the vulcanization process of rubber seals?

返回列表 Source: Cixi Haisheng Rubber Products Co., Ltd. Date2019-01-04 16:32 Browse: -

What causes the rubber seal to perform poorly during the vulcanization of the rubber seal? For example: insufficient rubber vulcanization working time or vulcanization working temperature does not meet the standard, that is, the vulcanization degree is insufficient (also called undersulfur), and the physical properties of the seal product are not achieved, such as low hardness, low strength, elongation, and large deformation The characteristics such as elasticity and elasticity cannot be used normally, which has a greater relationship with the degree of sulfur deficiency.

However, if the vulcanization time is too long or too high (commonly known as over sulfur), the physical properties of the rubber seal ring become low, which affects the rubber material properties of the seal. Follow-up can be observed through the vulcanization curve. If the torque continues to increase with time, the hardness of the sulfur compound is greater than that of the normal vulcanized AC. If the torque is decreasing with time, then It can be explained that excessive sulfur has caused the rubber to explain excessive cross-linking, and cross-linking may cause softening and tackiness. We need to do a good job in time to avoid such things.

Therefore, the process of vulcanization is very important, it will cause the performance of the rubber seal ring to fail to meet the standards, so that it may become unusable or have a shorter service life. If you have more questions, welcome to the official website for consultation
