Modified silica sol: Silica sol is used in these places in life

Cellophane and plastic film tend to become sticky in summer. Good results are

obtained if a mixture of colloidal silica and glyceryl monostearate is used. Treating

photosensitive paper with a mixture of silica sol and photosensitive liquid can smooth

the surface ofthe paper, brighten the image, and increase the exposure range. It can be used as a pre-coating film for printing paper, copy paper, and offset paper to make the paper surface smooth, and the image contrast is clear and has good contrast. After the surface of

kraft paper and corrugated paper is treated with silica sol, it can improve the anti-skid performance of paper, reduce the slippage of stacking layers during transportation, and improve the moisture resistance and strength of paper products. In the production of nongray carbon paper, using silica sol instead of clay, talcum powder and silica powder coating can make its color more vivid. Punched cards used in electronic computers,

coated with colloidal silica, have high stability, slip resistance and good printability.

The combination of silica sol and wool oil can improve the spinnability of wool,

reduce end breakage, avoid flying flowers, and reduce the reject rate. When used for

yarn sizing, it can improve the adhesion of the size, make it easy to fall off, and

shorten the drying time. Added to textile resin, it can make the yarn non-slip, make the fabric tidy and monotonous, and control the luster of the fabric.

In addition, silica sol can also be widely used as a treatment agent for various fabrics,

such as fabrics made of nylon, viscose fiber, acetate fiber, polyester, polypropylene, etc. After treatment, they all have the advantages of matting, non-slip, wear-resistant, washable, pollution-resistant, and anti-static.

The silica sol or silica gel solution used for brewing soy sauce can effectively absorb

various impurities in soy sauce, improve the clarity of soy sauce, and avoid secondary

precipitation and microbial reproduction. Compared with natural sedimentation

filtration, impurities can be separated more thoroughly in a short time. After the beer

fermentation stops, acidic silica sol is added to the solution to make impurity ions form coagulation and be removed, making the product clear and transparent. It can also be

used as a scavenger for rice wine, soy sauce, fruit juice, etc. , without affecting the color,aroma and taste of the product.
