Overview

Description

Acidic silica sol is a colloidal solution formed by the uniform diffusion of silica particles in water. The pH is 2-4. It has many excellent properties and characteristics. As a fine chemical product, it is widely used in textiles, electronics, refractory materials, and solid batteries. , food, synthetic resin, metal surface treatment, inorganic architectural coatings, agricultural fertilizers and other fields. Ion exchange method is the most mature preparation process for preparing acidic silica sol. This method uses water glass as a raw material and can usually be divided into three steps: preparation of active silicic acid, preparation of alkaline silica sol and cation exchange.
