Application scope and function of nano silica products:
1. Coatings Nano silica dispersion has been widely used in various coatings, with unique water-resistant, fire-resistant, scrubbing-resistant, and foul-resistant properties; It can prevent caking and sagging, and can also provide emulsifiers, fluidization, matting, supportive, suspension, thickening, thixotropic agents, etc.;
2. Thickening, thixotropy and fluidity control in adhesives and sealants, increasing adhesive strength, improving temperature resistance, ensuring free flow, preventing caking, maintaining transparency, anti-sagging, reinforcement, shear resistance, etc.;
3. Refractory materials Due to the excellent energy-saving and high-temperature resistance, the nano-silica dispersion is widely used as a thermal insulation material in process furnaces and other heat treatment equipment, with the advantages of high demoulding strength, stable high-temperature volume, good high-temperature thermal shock resistance, etc., and can also be used to prepare equipment with strong acid resistance;
4. In the textile industry, the combination of nano silica dispersion and crude oil can improve the preventability of wool, reduce broken ends, prevent flying flowers, and improve the yield of finished products; Used in light yarn slurry, it can improve the adhesion of the slurry, and it is easy to drop the sizing, so that the drying time is shortened, etc.; It can improve the antistatic ability of fluff, and the textile treated by nano silica dispersion has the advantages of matting, anti-slip, wear-resistant, washable, pollution-resistant, anti-static, etc.;
5. Papermaking industry The nano silica dispersion is mixed with photosensitive night, which can make the photosensitive paperboard smooth, the image is clear, and the range is increased; It is used for the pre-coating of drawings, copy paper and offset paper, which can make the paper surface smooth, the image contrast is clear, and the contrast is good; It can improve the slip resistance of paper, reduce the slippage in transportation and accumulation, improve the moisture resistance strength of paper products, have high stability and slip resistance, and have good printability;
6. Precision casting Due to its good adhesion, low shrinkage and perfect glass phase conversion at high temperature, nano silica dispersion is widely used in the precision casting industry;
7. Polishing slurry Nano silica dispersion has the characteristics of small particle size, high concentration and good dispersion, which is used in polishing slurry, mainly by chemical action, and can solve traditional problems such as surface roughness, waviness and surface defects by adding chelating agents and active agents.
Recommended dosage: Due to the wide range of applications of this product series, the addition amount of different systems varies greatly, and the general range is 2 30%, which needs to be determined after experiments.
