1. Liquid silica gel process: generally in the processing technology of liquid silica gel raw materials, low-degree silica gel sealing ring can be achieved, for example, 0 degrees to 20 degrees. Usually in industrial manufacturing, the liquid process uses more hardness of 10 degrees to 20 degrees. 2. Solid molding process: At present, in the silica gel industry, when the sealing ring is processed by solid silica gel process, can do about 30 degrees of hardness, higher degrees can also do, but its bad rate is very high... 3. general for custom hardness of silicone sealing ring processing, whether it is liquid or solid, there is a certain degree of difficulty.

Sealing ring-is a kind of can prevent fluid transmission, such as our well-known plastic or glass bottle, the lid will usually have a circle of rubber circle object, that is what we call the sealing ring.

Rubber seals are parts that prevent fluid or solid particles from leaking from adjacent joint surfaces and prevent external impurities such as dust and moisture from invading the inside of machinery and equipment in the sealing device. Many factors need to be considered when selecting reclaimed rubber for seals.

Manufacturers teach you to choose "silicone seal ring"? Silicone seal ring because of its role and more and more popular, to understand the knowledge of silicone product output.

The choice of rubber sealing ring of B- type rigid waterproof casing B- type rigid waterproof casing is through the gap between rubber ring sealing and pipeline. different sealing forms and sealing ring materials directly affect the sealing effect of B- type rigid waterproof casing.

Do you know how many kinds of silicone seal ring seal, I believe that everyone has a very good understanding of silicone seal ring, because the use of silicone seal ring is very extensive.

As a traditional rubber variety, natural rubber has good elasticity, strong strength, high wear resistance, high tensile strength and elongation at break and other indicators. It can be used to produce rubber seals working at -20 ℃-100 ℃ without oil and corrosion.

The commonly used rubber sealing ring material is mainly synthetic rubber. Because there are many kinds of synthetic rubber, and their properties are also different. Therefore, in addition to meeting the above requirements, the selection should be based on the characteristics of different kinds of rubber. And the scope of use.

Rubber ring is one of the indispensable parts in the installation of ductile iron pipe, the rubber ring must be used to seal the installation of ductile iron pipe, so the quality of the rubber ring is directly related to the safety of ductile iron pipeline engineering.

The problem is that the application is so wide that the quality must be put first. Let's talk about how to choose silicone seal products and which details should be paid attention to. The quality must first depend on the characteristics of silicone seals.
