Reasons for aging of rubber joints and how to prevent aging

The important reason that affects the use of rubber joints is the oxidation of pressure and air in the process of use. Rubber and its products in the process of processing, storage and use, due to the comprehensive effect of internal and external factors and caused by the gradual deterioration of the physical and chemical properties of rubber and mechanical properties, evolved to no use value, this change is called rubber aging. The surface is cracked, sticky, hardened, softened, chalked, discolored, moldy, etc. Therefore, the bendable rubber joint should be checked regularly in the process of use, and some of them should be maintained and replaced regularly when they are used for more than years and aging is more serious.
 
When using or storing soft adhesives, rubber joints should be protected from high temperature, ozone oil and acid and alkaline environment. Outdoor or sunny roof ducts shall be set up with sunshade and shall not have wind and rain. Paint and windproof materials shall not be applied to the joint surface. Because of the aging problem of rubber products, it is necessary to view and replace them in time. Equipment bolts should be symmetrical and tightened gradually to prevent partial leakage.
 
 
Pay attention to the method during installation as a way to prolong the service life of rubber joints. When installing rubber joints, they should be left in their natural state and the product should not be artificially deformed during installation. This will lead to early damage and weakening of the product's use. If the product is installed at the near end of the outlet of the pump or the corner part of the pipeline, as well as the high pressure and high-rise building overhang, the pipeline shall have fixed support or fixed bracket, and the force of fixed support and fixed bracket shall be greater than the axial force, otherwise the rubber joint shall be installed with anti-pull-off limit device.
