The aging problem of rubber sealing strips has always been a problem that plagues the sealing strip industry. At present, the application of rubber in the sealing strip industry is still very wide, so solving the aging problem of rubber is very important for the development of the sealing strip industry. At the same time, the aging problem is the most important factor affecting the sealing of the sealing strip.
The aging of rubber mainly refers to the occurrence of cracks, hardening, discoloration, cracks, etc. on the surface of the rubber during use or storage.
The main factor affecting the aging of the sealing strip is the natural environment. First, the influence of oxygen, ozone and other air components is mainly caused by the oxidation reaction, which causes the molecular chain of the rubber to break, but the degree of influence of ozone and oxygen is different. Ozone is more oxidatively destructive. Second, the influence of light and moisture, which is the key factor to accelerate aging, the moisture in the air is the necessary condition to soften the rubber, and the light is the main factor to promote its discoloration. Long-term sunlight can easily cause rubber. The deformation is softened. Third, the temperature and temperature have a relatively large effect on rubber. The main reason is that in the cold winter, if the rubber hardens, the rubber will break, and the hot summer will soften the rubber.
The above points are the most important factors that cause the rubber seal to age. Therefore, when cleaning the seal, it should be started from the above aspects of waterproofing, air isolation and heat preservation.
