More and more silicone products are hot in the market, and there are inevitably advantages and disadvantages. Some silicone products feel that the surface is not smooth enough after a period of use, and there is still a sticky feeling, especially in kitchen utensils, or the silicone phone case is obvious. What is the reason for the uneven surface of silicone products?
1. Raw material problems, or improper maintenance.
2. It is unreasonable to control and use the curing agent during the raw material mixing process. The amount of curing agent added did not fully cure, causing the product surface to become sticky.
3. The curing agent and the silica gel are not uniformly stirred during kneading, and the mold is cured while curing, and the product is deformed due to the difference in hardness and hardness after the product is cured.
4. When the machine is cleaned, the mold is not cleaned, and the mold is not smooth enough. Residues in the mold can cause uneven product and make the product surface not smooth.
5. There is no secondary vulcanization spraying hand oil, etc., that is, the treatment is not enough.
