What is the processing process of the T-shaped anti-skid and anti-degumming ring?

1. Vulcanization process

The vulcanization process is one of the important processes in the production of rubber sealing rings, and temperature and time are the main control conditions of this process.

Rubber is a poor conductor of heat, especially during the molding and heating process of thick products, the temperature is always transferred from the outer layer (mold) and the inner layer (mandrel) to the center layer after a certain period of time, so that different parts of the product are affected by the distance from the heat source. There are obvious temperature gradients. Therefore, the vulcanization process is actually a non-isothermal process with uneven temperature field distribution. In order to achieve optimal vulcanization everywhere under different vulcanization conditions, the temperature distribution must be displayed and controlled. Some large domestic tire factories use vulcanization temperature measurement as a means of vulcanization quality control and daily monitoring and management.

2. Mixing process

The quality of mixing is directly related to the performance of the product. The controllable parameters of the rubber gasket mixing process include factors such as time, temperature, energy, and instantaneous power, and these parameters are closely related to the quality of the rubber compound. It is meaningful to study these parameters for quality control. Unvulcanized rubber instantaneous power-time curve, temperature-time curve, energy-time curve and time, weight of rubber compound and filler. Use these data to find an optimized process.

When designing the production process, rubber sealing product manufacturing enterprises should improve the performance of the product's service life indicators such as compression deformation resistance, compression stress relaxation resistance, and aging resistance as much as possible. At the same time, the control of hygiene indicators in the production process is also particularly important.
