Silicone ring sealing effect is poor, what is the reason for the sealing effect?

2022-08-16
Latest company news about Silicone ring sealing effect is poor, what is the reason for the sealing effect?

Aging life ability is the hard damage of silicone ring, all suitable for sealing silica gel products have such a defect, such as our common mechanical doors and Windows, electronic product sealing and automotive waterproof sealing ring will appear certain defects, Whether silicone or rubber and other materials are selected, they will gradually lose their functionality and fail to achieve the actual effect after environmental destruction and the test of time, and can not show the role of the product.

There are many main reasons to affect the service life, but in any sealing silica gel ring will be affected by several common phenomena.

The force size affects or compresses the permanent, according to the installation mode, plane, concave and convex groove or groove and other different ways of installation, installation of each product is likely to lead to uneven force, force center deviation, one side is heavy and the other side is light, which leads to compression permanent deformation after long-term stress accumulation. When it is unloaded again, the sealed silicone ring is likely to have been deformed, so it is necessary to control the balance and the degree of force uniform synthesis while installing.

The product size is wrong, resulting in gap deformation:

Gap problem can be divided into several factors, because the material of the rubber problem, a lot of silicone material appeared due to the formula back stretch is poor, the problem of insufficient tensile force will cause in the process of using the strength is not big gap lead to leakage, silica gel circle machining manufacturer problem: crisp lead to silica gel products such as product do edge thickness of thin easy to appear this kind of problem, When the product is soft, the rubber material has inner bulging and is not ripe, and the gap problem occurs after long-term tensile and compression deformation.

Product soft or brittle lead to function failure, most of the time is not the structure of materials and products, but in the process of silicone rubber products factory production lead to product quality standards, such as processing hard softness requirement, did not know when will lead to long processing time appear in the process of the product is too brittle in the installed appear cracking phenomenon, Or if you want to improve the processing efficiency, the product is soft, resulting in deformation phenomenon when the product is stressed.

Hard softness effects, and many times according to the different softness of silicone rubber products can completely change the product functional and structural, so the silicone seal in use process due to choose different hard softness after loading, stretching, the emergence of the phenomenon such as extrusion, sealing ring can appear some inevitable problems, such as extrusion aperture, too much stress, hardness is too high, Product deformation without rebound and other factors.
