What is the reason for the uneven surface of silicone products?
The surface of the silicone products on the market feels smooth and delicate, and the hand feels very good. However, after buying it back and using it for a period of time, it will obviously feel that the surface of the product is not smooth enough, and there is still a sticky feeling, especially on kitchen utensils and protective cover products. What is the reason for the uneven surface of silicone products?
The first reason is that the control and use of the vulcanizing agent during the mixing of the silicone raw materials is unreasonable, and the silicone products with a small amount of vulcanizing agent are not fully vulcanized, resulting in a sticky surface of the products.
Secondly, the vulcanizing agent and the silica gel are not uniformly stirred during mixing, and the mold is not vulcanized while being vulcanized, resulting in the deformation of the product due to the difference in hardness and softness after molding and vulcanization.
Finally, the mold is not cleaned properly during production, the inside of the mold is not smooth enough, and the mold contains residual material, which leads to the unevenness of the heavy material of the product, resulting in an uneven surface of the product.
