Uses: It is widely used in chemical, electronic, integrated circuit (IC), electric appliance, plastic, paint, advanced paint, rubber, national defense and other fields.
Cement or concrete admixture:
Microsilica powder can fill the pores between cement particles, while generating gel with hydration products and reacting with alkaline material magnesium oxide to generate gel. In cement-based concrete, mortar and refractory casting materials, mixing the right amount of silica fume can play an important role.
Refractory material additive:
High quality microsilica powder is mainly used as high performance refractory castables, prefabricated parts, ladle materials, breathable bricks, self-flowing refractory castables and dry and wet injection materials. In the field of high temperature ceramics, such as: oxide bonded silicon carbide products, high temperature type calcium silicate light insulation materials, corundum mullite pushing plate for electromagnetic kilns, high temperature wear resistant materials and products, corundum and ceramic products, selon bonded products, etc., micro silica powder is used with high fluidity, low water storage, high density and high strength.
Metallurgical pellet binder:
Micro-silica powder is blended with water to make pellets and then dried or sintered naturally without adding binder, and the pellets have few impurities and can be returned to the electric furnace as smelting material.
Chemical product dispersant:
In order to prevent some chemical synthetic powder from caking, micro-silica powder can be used to replace the more expensive treatment materials, instead of partial dispersion isolation and or increase the effect, widely used in micro-fine pesticides, fertilizers, fire extinguishing agents and other products.
