Black spots appear on the surface of silica gel products. Impurities are mainly distributed in white, transparent colors and other bright colored products. This phenomenon is also plagued by silicone product manufacturers.
The first step is to check whether black spots are present during the mixing of raw materials.
The second is to ensure that the machine and the surrounding health are done.
Third, due to the strong adsorption of silica gel, it is necessary to pay attention to the dust and stick raw materials, and the compounded rubber must be sealed.
