Improve compressive strength, bond strength, abrasion resisitance, reduce permeability in construction application.
Improve the fluidity of refractory casting materials, improve the compactness, temperature strength and thermal shock resistance. Reduce water consumption in refractory application.
As dispersant for chemical products, micro silica instead of mica or diatomite to prevent fertilizer particles caking. Making potassium silicon compound fertilizer, protect the soil from erosion or deterioration.
With strong adsorbability and large specific surface, as anti-caking agent or pellet binding agent improve economic performance.
