What are the reasons for the degumming of the nitrile skeleton oil seal

1. Come to know the reasons for the degumming of the nitrile Skeleton Oil Seal with the Zhongxingshun Seal manufacturer

The so-called degumming means that the nitrile rubber material and the skeleton material are separated from each other, and the two cannot be bonded. In the actual production process, rubber product manufacturers can find the reasons for degumming from the aspects of skeleton materials, adhesives, and production process parameters.

(1) Skeleton material: When the surface of the skeleton material is glued, there are oily substances that are not completely cleaned, which will cause the adhesive and the skeleton material to fail to bond; the surface of the nitrile skeleton Oil Seal skeleton material is contaminated after the adhesive is applied. Adhesion of dust, mold release agent, oil and other substances will cause the adhesive to fail to bond with the skeleton material. Imported Seals

(2) Adhesives: The role of adhesives in skeleton oil seals is irreplaceable. Using expired adhesive 2LLYY55-SJ or unqualified adhesive, the failure of the adhesive will lead to degumming of the nitrile skeleton oil seal. In the production process, the surface coating or primer coating is not dry, and the adhesive on the surface of the skeleton material is too thick, which will also cause the nitrile rubber part and the skeleton material to not be firmly bonded.

(3) Production process: When nitrile rubber is used to produce skeleton oil seals, the skeleton material remains in the high-temperature mold for too long, and a sudden power failure when the glue injection is not started after the mold is closed will cause the adhesive to fail; during the production process of the skeleton material, the mold seals One of the main reasons for the degumming problem of the skeleton oil seal is that it is not strict and the injection hole is too large. Therefore, rubber product manufacturers must strictly control the production process.

2. How to avoid degumming of nitrile skeleton oil seal

When using nitrile rubber to produce TTO skeleton oil seals, the entire production process needs to be carried out in a clean environment to avoid external impurities leading to degumming of skeleton oil seals; choose appropriate types of adhesives according to actual needs, and choose high-quality adhesive products; design molds in total and clean them in time The mold, especially the important parts such as the injection hole; strictly control the mold temperature and control the production process at any time; effectively avoid the degumming of the nitrile skeleton oil seal in all aspects.

The nitrile skeleton oil seal is used in the parts that need to be lubricated in the transmission parts and the output parts to avoid the penetration of lubricating oil. The skeleton material can play a significant role in strengthening the nitrile oil seal to ensure that the oil seal can maintain a certain shape and tension. Degumming is a common appearance defect in the production process of nitrile skeleton oil seals. There are many reasons for the degumming of skeleton oil seals. Rubber product manufacturers can choose appropriate solutions according to the reasons.
