The aging problem of automotive sealing strips has always been a difficult problem that has plagued the operation of sealing strips. Now, the use of sealing strips in the industry is still very extensive. Solving the aging problem is crucial to the development of sealing strip operations. At the same time, the aging problem is a relatively important factor affecting the sealing function of sealing strips.
The main factor affecting the aging of sealing strips is the natural environment. First, the influence of oxygen, ozone and other components in the air. First, the oxidation reaction causes the molecular chain of rubber to crack, but the degree of influence of ozone and oxygen is different. The oxidation destructiveness of ozone is greater. Second, the influence of light and moisture, which is a key factor in accelerating the aging of sealing strips. Moisture in the air is a necessary condition for the softening of rubber. Light is the main factor that promotes its discoloration. Long-term sunlight exposure is very easy to cause rubber deformation and softening. Third, temperature, the impact of temperature on rubber is still relatively large. First, in severe winter, the rubber will harden, and in severe cases, it will also cause rubber cracking, and hot summer will soften rubber.
The above points are the main factors that promote the aging of rubber sealing strips. Therefore, when maintaining the sealing strip, we should first start from the above aspects of waterproofing, air isolation and heat preservation.
Rubber materials are very common in our lives. After a long time, we will find that rubber sealing strips are actually difficult to preserve, especially in summer, in a high temperature environment for a long time, the rubber sealing strip is more likely to melt and deform. Therefore, when preserving or maintaining the sealing strip, we must pay attention to the following points:
First, avoid long-term direct sunlight. Too strong sunlight is fatal to the aging of rubber. Rubber is generally black and has a strong heat absorption ability. Therefore, it will cause the temperature to rise, and then change its physical properties. The more direct effect is softening.
Second, avoid high temperature environment. As mentioned earlier, direct sunlight will cause high temperature deformation. Another harm of high temperature is that it will cause rubber to melt.
Third, the storage environment of rubber sealing strips should be monotonous, which is also an important factor to prevent its aging.
In a word, the storage environment of rubber sealing strips is a light-proof, cool and monotonous environment.
The storage environment should be monotonous, which is also an important factor to prevent its aging.
