Then dripping the dilute silicic acid solution into a reaction kettle, gradually polymerizing silicic acid into silicon dioxide nano particles under the alkaline condition by controlling the pH value and the temperature of the system, and then concentrating to obtain a finished product of silica sol. This method is used by many enterprises due to low raw material cost. Although the silicon powder hydrolysis method has simple production process, the adopted silicon powder raw material has higher price and higher cost.

In the process of the ion exchange method, the exchange effect and the exchange efficiency of the ion exchange column directly influence the product quality and the production efficiency of the silica sol. The ion exchange column can generate gel-like substances after being used for a period of time to harden the exchange resin, which not only affects the exchange efficiency, but also causes the defects of difficult resin cleaning and long cleaning time.
