How to add color to silica gel raw materials?

1.The raw material of silica gel is made by adding silica gel masterbatch or toner to the open mixer for repeated mixing. During the mixing process, we need to repeatedly cross-mix and mix evenly before it can be put into use. If the mixing is not uniform, the silica gel products Obvious color marks will appear during production.
2.At present, most of the manufacturers on the market produce colored silicone raw materials. Usually they send the color specified by the customer to the color paste manufacturer for color matching to formulate the corresponding color silicone masterbatch, and then color it. Although this method is simple, the cost is relatively high. . Manufacturers specializing in the production of colored silicone raw materials usually have independent color matching capabilities, and only a few basic colors are repeatedly mixed to produce the ideal color. This method can greatly save production costs and avoid unnecessary cost burdens.
4.In addition, we can make the color we want by adding toner, but this method is more difficult and not recommended. The reason is because the toner composition of various colors is different, and the particle mesh size is different. The lower the mesh number, the larger the particle size, which is not easy to mix with the silica raw material, and it is easy to cause the surface of the raw material to appear. Color marks. The finer the particles of the high-mesh toner are, the easier it is to mix during the mixing of silica gel raw materials, but the higher the cost of the high-mesh toner.
4. Generally speaking, it is the easiest way to add silica gel masterbatch directly to the raw material of silica gel. In the process of adding toner, it is easy to cause the toner to fly, causing the error of the addition ratio to affect the color appearance, and it is easy to cause workshop pollution. Therefore, the method of adding toner to the raw material of silica gel is not recommended.
