There are several aspects that affect the service life of rubber joints

        Rubber products are made of natural rubber and other synthetic rubbers in a proportional formula. They will oxidize and corrode over time. Rubber joint products contain volatile substances. Whether in a humid environment or in a dry environment, it will shorten its life. Therefore, generally rubber products should be packed in plastic bags after use, and should not be exposed to the air for a long time. This is also an effective way to extend the life of rubber products. However, rubber joint products are generally installed and used on pipelines. How do we protect these after long-term operation? Flexible rubber joint products used in outdoor environments.      

        1. Mechanical stress: Under the repeated action of mechanical stress, the rubber molecular chain will be broken to generate free radicals, which will trigger the oxidation chain reaction and form a mechanochemical process. Mechanical breaking of molecular chains and mechanical activation of oxidation process. Which one has the advantage depends on the conditions. In addition, it is easy to cause ozone cracking under stress.

       2. Moisture: The role of moisture is divided into two aspects: when rubber is exposed to rain or immersed in water, it is easy to destroy, because the water-soluble substances and hydrophilic groups in rubber are extracted and dissolved by water. , Hydrolysis or absorption and other reasons. Especially under the alternating action of water immersion and atmospheric exposure, it will accelerate the destruction of rubber. However, in some cases, moisture does not have a destructive effect on rubber, and even has the effect of delaying aging.
