Good morning, silica fume is a kind of common solid powder defoamer and suspension thickener. Because of its large specific surface area, it can reduce the surface tension of liquid in aqueous solution or solvent to obtain static defoaming force, such as soybean milk and water-based paint. Its defoaming effect can only be temporarily effective and can not be used for a long time. Generally, it is necessary to use a small amount of dimethyl silicone oil to disperse with white carbon black.
