The vulcanizing machine is a kind of mechanical equipment often used in the production of silicone products, which greatly improves the production efficiency. However, there are many factors that will affect the performance and vulcanization effect of the equipment during the use of the equipment. These influencing factors can often be avoided in advance. Regular maintenance of the equipment, timely inspection and replacement of damaged parts, etc., are all helpful to ensure Equipment performance and vulcanization effect.

1. Sulfur dosage
The greater the amount of sulfur used in vulcanizing machine mechanical equipment, the faster the vulcanization speed will be, and the higher the vulcanization process will be. However, the solubility of sulfur and rubber has a certain limit, and it does not mean that the greater the amount of sulfur used, the better. Excessive sulfur It will be precipitated from the surface of the rubber compound. This phenomenon is called “sulfur spraying”. To minimize the occurrence of sulfur spraying, the method is to add an appropriate amount of sulfur at the lowest possible temperature. Generally, the amount of sulfur is greater than that of soft rubber. Do not exceed 3%, semi-hard glue does not exceed 20%, and the amount of pure hard glue is higher, reaching more than 40%.
2. Vulcanization temperature
The vulcanization temperature determines the uniformity of vulcanization. When the temperature is 10°C higher, the vulcanization time will be shortened by about half, and rubber is a poor heat conductor. The temperature control is very critical, and the temperature should be raised gradually. The principle is to vulcanize at low temperature for a long time.
3. Vulcanization time
The vulcanization time is an important link in the vulcanization process. If the vulcanization time is too short, the product cannot be molded, and if the time is too long, the product effect will not be good.
Many factors will affect the performance stability and vulcanization effect of the vulcanizer equipment, so in the actual operation and use of the equipment, in order to maintain a stable and suitable operating speed of the equipment, when the vulcanization performance and effect of the equipment are not good, do not worry. To solve the problem, it is necessary to find the cause of the mechanical failure, and then take targeted solutions, so as to ensure the vulcanization performance and effect of the equipment.
