Applications in the paper industry

Cellophane and plastic film tend to become sticky in summer [8]. If treated with a mixture of silica sol and monostearyl glyceride, it can be solved successfully. The photosensitive paper is treated with a mixture of silica sol and photosensitive liquid, which can make the surface of the photosensitive paper smooth, clear the image, and increase the exposure range. It is used as a pre-coating layer for printing drawings, copy paper and offset paper, which can make the paper surface smooth, the image contrast is clear, and the contrast is good. After the surface of kraft paper and corrugated paper is treated with silica sol, it can improve the slip resistance of the paper, reduce the slippage of the stack during transportation, and improve the moisture resistance and strength of the paper. In the manufacture of non-gray carbon paper, the use of silica sol instead of clay, talc and silica powder coating can make the color more vivid. Perforated cards used in electronic computers, after being coated with silica sol, can have high stability and slip resistance, and good printability.
