Silicone products have a wide range of applications. Because they are non-toxic and environmentally friendly, and do not rely on petroleum resources, silicone products appear in all aspects of our lives. So under what circumstances will the quality of silicone products be affected?

1. The quality of silicone raw materials: The quality of raw materials will make silicone products difficult to remove. Poor quality silicone raw materials have insufficient toughness and obviously insufficient tear strength. It is definitely difficult to remove the edges during the removal process.

2. In the molding process: The product is relatively thick, so the burrs are actually thicker. The increase in thickness will definitely lead to difficulties in removing the edges.

3. Problems with molding molds: If the mold self-disassembly design is unreasonable, the molding mold is used for too long, and the quality of the molding mold is not up to standard, these situations will make it difficult to remove the edges after production molding.

4. Vulcanization environmental factors: The vulcanization temperature should be appropriate. Problems that are too high or too low will make it difficult to remove the edges. At the same time, the vulcanization time also needs to be well controlled. Too long a vulcanization time will make the product brittle, and too short a vulcanization time will cause the vulcanization process to be ineffective. Therefore, the vulcanization process must be well controlled in silicone product factories.

The correct way to choose rubber seals is:.
1. Direction of movement - first determine the direction of movement of the seal, such as reciprocating, rotating, spiral or fixed.

2. Sealing focus - for example, determine the active point is the rod seal on the inner diameter or the piston seal on the outer diameter.

3. Temperature level - check the original machine instructions or evaluate the working temperature according to the actual working environment to determine the required use data. Silica gel products have an open porous structure and can absorb many rubber product substances. They are a good desiccant, adsorbent and catalyst carrier. The adsorption effect of silica gel is mainly physical adsorption. It can be regenerated and reused. Add acid to the alkali metal silicate (such as sodium silicate) solution to acidify it, and then add a certain amount of electrolyte to stir it to generate silica gel, or add acid or ammonium salt to a concentrated sodium silicate solution to generate silica gel.

4. Pressure level - check the relevant data from the original machine instructions, or infer the working pressure level by observing the hardness and structure of the original seal.
