Analysis of the reasons leading to the failure of the silicone sealing ring

With today’s technology and technology, the sealing protection technology of many products still has certain defects in the actual process, and the use of silicone (a kind of rubber material) for the seal material is our more common one, so the silicone rod seal As a type of seal used in many aspects, there will often be some unexpected functional problems during normal use. The actual problem can not be achieved, and the effect of the product cannot be displayed. Then I will take you to understand the impact of the silicone sealing ring. What are the usage factors?

The impact of the hardness and softness of the silicone sealing ring: In many cases, the functionality and structure of the product can be completely changed according to the different softness of the silicone product. Therefore, the silicone sealing ring is subjected to stress due to the selection of different hardness and softness during use. , Stretching, squeezing and other phenomena, the sealing ring will have some unavoidable problems, such as extrusion gap, excessive force, too high hardness, product deformation without rebound and other factors.

Silicone sealing ring gap problem: The gap problem can be divided into several factors. One is because of the material's rubber problem. Many silicone materials have poor resilience due to formula and insufficient tensile force, which leads to problems in the use process. If the force is not strong, the gap will cause leakage, and the silicone ring manufacturer’s processing problems, such as the product that is brittle and the product with a thinner curling thickness, is prone to this problem, and the soft product causes the rubber to be bulging and not familiar. After long-term stretching and compression, there will be gap problems in deformation.

The force process of the silicone seal ring: The silicone seal ring is generally installed in several places, grooves, planes, and convex grooves. The installation method of each product is different. The force process will also affect the service life and function of the product. Therefore, in order to ensure the sealing performance, this memory will be reserved to distinguish the different methods and stress levels of the silicone rubber sealing ring. For example, the plane installation can be affected by the tightness of the deployment, concave and convex. What is the degree of force on the action, and the degree of reservation in the selected size.

What I have introduced above is the analysis of the causes of the failure of the silicone sealing ring, I hope it can be helpful to everyone.
