The aging problem of rubber sealing strip has always been a difficult problem in the sealing strip industry. At present, the application of rubber in the sealing strip industry is still very wide, so it is very important to solve the aging problem of rubber for the development of the sealing strip industry.
The aging problem of rubber sealing strip has always been a difficult problem in the sealing strip industry. At present, the application of rubber in the sealing strip industry is still very wide, so it is very important to solve the aging problem of rubber for the development of the sealing strip industry. At the same time, aging is the most important factor affecting the sealing of the sealing strip. The aging of rubber mainly refers to the phenomenon of cracking, hardening, discoloration and cracks in the use or storage of rubber. 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 the occurrence of oxidation reaction, which breaks the molecular chain of rubber. However, the influence degree of ozone and oxygen is different, and the oxidation of ozone is more destructive. Second, the impact of light and moisture, which is a key factor in accelerated aging, moisture in the air is a necessary condition for the softening of rubber, and light is the main factor to enhance its discoloration, long-term sunlight can easily make rubber deformation and softening. Third, the influence of temperature and temperature on rubber is still relatively large, mainly in the cold winter, if the rubber is severely hardened, it will cause the rubber to break, and the hot summer will soften the rubber.
The above points are the main factors that promote the aging of the rubber sealing strip, so when maintaining the sealing strip, it should be mainly from the above waterproof, air isolation and heat preservation.
