Vulcanization temperature of the rubber press is too high?

The rubber press of the vulcanizer. If the temperature is 10 °C higher, the curing time will be prolonged by about half. In order to ensure a relatively average vulcanization level, individual thick rubber products are gradually heated and vulcanized at high temperature for a long time. The metal material of the vulcanizer is exposed to the air for a long time, and it is easy to be corroded. Once corroded, its function will be affected, and the service life of the flat vulcanizer will be greatly reduced. Therefore, the anti-corrosion operation of the vulcanizer is very important. We generally take the following points for fundamental prevention and control.

    All materials of the vulcanizer are made of corrosion-resistant materials; all descriptions refer to anti-corrosion descriptions; corrosion-resistant metals or non-metals with strong corrosion resistance are used; the use of corrosion inhibitors for flat vulcanizers. In other aspects, the anti-corrosion treatment of the flat vulcanizer can also be carried out by means of surfacing welding, thermal spraying, adhesive, electroplating, electric brush plating, etc. Through the above methods, the corrosion of the vulcanizer can be effectively prevented, and the service life of the flat vulcanizer can be improved.

    The amount of sulfur used in the vulcanizer. The greater the amount of sulfur used, the faster the vulcanization rate and the higher the vulcanization level that can be achieved. The solubility of sulfur in rubber is limited, and an appropriate amount of sulfur will be precipitated from the surface of the rubber compound, commonly known as "sulfur spray". The amount of sulfur in soft rubber is not more than 3%, the amount in semi-rigid rubber is about 20%, and the amount in hard rubber vulcanization can be as high as 40% or more.
