There are many kinds of silica sol. According to the type of silica sol, there are many kinds of silica sol. PH value. Particle size. Purity. Concentration. Can be divided into acidic silica sol. Neutral silica sol. Alkaline silica sol. Ammonia type silica sol. High purity. . Among them, acidic silica sol, also known as silicic acid aqueous solution, is a colloidal solution obtained by dispersing polymer silica particles in water.
1. Silica sol has strong adsorption. Under certain conditions, a large number of network gaps generated by a large number of micelles in the silica sol can adsorb inorganic and organic substances.
2. Silica sol has a larger specific surface area. The specific surface area is 150-300M2/g..
3. Silica sol has good adhesion. Due to the uniform size of the micelles, about 10-20 m/u, a smaller bond strength will be produced after air-drying. If silica sol is added to a certain fiber or granular material, it will become a firm gel structure after drying and curing, resulting in greater adhesion.
4. Silica sol has good temperature resistance. Can afford 1 yuan. ℃ high temperature.
5. Silica sol has good hydrophilicity and strong oleophobicity. Distilled water or ion-free pure water can be diluted to any concentration, and the stability increases with the dilution; when added to organics or various metal ions, it will produce oleophobicity.
6. Silica sol has high dispersibility. Good abrasion resistance and light transmittance can be used as a good dispersant, antiseptic, flocculant, coolant, etc.
Acidic silica sol also has high dispersion properties such as large surface area, large adsorption force, good adhesion, good high temperature resistance, good water resistance, and good slip resistance. Acidic silica sol is mainly used in textiles, electronics, refractories, solid batteries and other fields. Silica sol has been used in many industries, widely used in various fields of production and life, and plays an important role in people's daily life.
