Why is there always a small hole when the fluorine rubber ring is formed?

There are two main reasons for the small holes on the surface of the fluorine rubber ring. First of all, fluorine rubber is a synthetic polymer material, and its molecular structure contains fluorine atoms, which makes the intermolecular force of the material strong and the molecular chain difficult to fully stretch. Secondly, the fluorine rubber ring needs to undergo high temperature vulcanization during the molding process, which may cause some gases to remain in the material and form small holes.

Fluorine rubber ring is widely used in various fields because of its excellent performance. In the automotive field, it can be used to manufacture automobile tires, seals, etc. In the aerospace field, it can be used to manufacture seals, insulation materials, etc. In the field of petrochemical industry, it can be used to manufacture seals, pipelines, etc.

In order to solve the problem of small holes on the surface of the fluorine rubber ring, the following measures can be taken:

1. Use a better mold: The use of high-precision mold, improve the surface finish and accuracy of the mold, can reduce the generation of small holes.

2. Improve the production process: Optimize the vulcanization process parameters, reduce the vulcanization temperature and time, can reduce the residual gas in the material, thereby reducing the generation of small holes.

3. Add plasticizer: Adding an appropriate amount of plasticizer to the fluorine rubber formula can reduce the hardness of the material, increase the plasticity and extensibility of the material, so that the molecular chain is easier to fully stretch, thereby reducing the generation of small holes.

In practical application, it is of great significance to solve the problem of small holes on the surface of the fluoro rubber ring. For example, in automotive manufacturing, if there are small holes on the surface of tires or seals, it may lead to air leakage or reduced sealing performance, affecting the performance and safety of the car. The above solution can effectively reduce the occurrence of small holes and improve the quality and reliability of products.

By using better molds, improving the production process or adding plasticizers, the generation of small holes can be reduced and the quality and reliability of products can be improved. Understanding and solving this problem is of great significance to improve the efficiency of industrial manufacturing and the service life of products.
