Cause analysis of failure of silicone sealing ringIssuing time:2019-11-13 17:59 Influence of hardness and softness of silicone sealing ring: in many cases, the functionality and structure of the product can be completely changed according to the different softness of silicone products. Therefore, during the use of silicone sealing ring, due to the selection of different hardness and softness, some unavoidable problems will occur in the sealing ring, such as excessive stress, high hardness, product deformation and no rebound, etc. The clearance problem of silicone sealing ring: the clearance problem can be divided into several factors. The first is the problem of the rubber material. Many silicone materials have poor resilience due to the formula. The problem of insufficient tensile force leads to little stress in the process of use, resulting in leakage. The manufacturer of silicone sealing ring has processing problems. For example, the product is brittle, resulting in thin curling thickness, When the product is softened, the inner bulge of the compound is not mature, and the crack problem occurs after long-term tension and compression. Stress process of silicone sealing ring: silicone sealing ring is generally installed in several places, such as groove, plane and convex groove. The installation method of each product is different, and its stress process will also affect the service life and function of the product. Therefore, in order to ensure the sealing performance, a reserved space will be made to distinguish the different methods and stress levels of silicone rubber sealing ring. For example, the tightness of the plane installation can be adjusted according to how much the plane installation can bear, The stress degree of concave and convex action is how much, and the reservation degree of size is selected. The above is the cause analysis of the failure of the silicone sealing ring. I hope it can help you. |
