The nano-silica sol production technology passed the qualification

Recently, the cationic hybrid nanosilica sol developed by Nantong China Resources New Materials Co.
, Ltd.
has passed the identification
of scientific and technological achievements.
Experts believe that the successful development of this technology will change the situation of China's dependence on imports of high-quality silica sols, and will help promote the transformation and upgrading
of China's downstream industries such as textiles, coatings, papermaking, chemicals, and electronics.

The problems of small particle size and poor uniformity of silica restrict the production of
high-grade silica sol products.
Nantong China Resources New Materials Co.
, Ltd.
improved the production technology of small particle size nanosilica sol by traditional ion exchange method, combined with the one-step dissolution method of elemental silicon, prepared nano silica sol with large particle size, high concentration, uniform and stability, and various technical indicators and performance reached the level of foreign mainstream companies, which can be replaced
.
The technology has been authorized by the state for invention patents, and has formed an annual output of 800 tons of industrial production capacity
.
