How to prevent aging of rubber joints
The main reason for aging of rubber joints is the weakness of structure or parts that can easily cause aging, but also the influence of external or environmental factors, mainly sunlight, oxygen, ozone, heat, water, mechanical stress, high - energy radiation, electricity and industrial gases. , seawater, salt spray, mold, bacteria, etc.
 
In terms of the causes of aging, one of the main reasons is in the polymer structure itself. Therefore, it is important to improve the structure of the polymer to enhance the aging ability. For example, rubber still has unsaturated double bonds after vulcanization, and it is difficult for rubber products to avoid sunlight, oxygen, ozone, etc. Therefore, people study the synthesis of new varieties to avoid or greatly reduce the polymer chains. Rubber. Double bond
 
For example, the copolymerization of ethylene and propylene two monomers made of binary ethylene rubber, which differs from other synthetic rubber in that the main chain does not contain double bonds and is completely saturated, making it the most ozone-resistant, chemical-resistant rubber. Resistant, high temperature and aging resistant rubber; the other is to add anti-aging agents, such as adding antioxidants to prevent aging caused by oxygen or ozone, adding ultraviolet stabilizers, heat stabilizers, anti-mold agents, etc., to neutralize the aging caused by aging. The unfavorable factors of aging.
 
Through the above introduction, we apply reasonably, and believe that we can protect the rubber joint well and prevent aging.
