Description
What is white silica
fume?
White silica fume ,also
know as Zirconia silica fume , is a compound of zirconium dioxide,
zirconium oxide melting products, the production of
silicon-zirconium off special device which used to collect the
silica powder, not only has the general characteristics of sillca ,
but also a certain amount of zirconia powder. White silica
fume has a special use in the field of refractories, injection
materials, ceramics and building materials industries and
high-strength concrete for its features of low impurities and good
activity in refractory.

high-grade.
1. widely used in
casting refractories ,fused and sintered refractories. Such as high
performance and low cement refractory materials and prefabricated
parts, large iron hooks and steel materials, ventilation tiles,
apply mending materials, etc. gravity-based refractory materials
and construction of dry and wet spray application; oxide silicon
carbide products(ceramics kiln with, every flame plate,
etc.);Lightweight high temperature calcium silicate insulation
material; Electric kilns with corundum mullite puser;
high-temperature resistant materials and products; corundum and
ceramic products.
2. For mortar and
concrete in : high-rise buildings, the harbor docks, dams, water
culvert, railway public bridges, subways, tunnels, airport runways,
concrete pavement and the coal mine tunnel shotcrete
reinforcement.
3. New wall materials,
decorative materials, wall thermal insulation mortar, insulation
mortar, interface agents.
4. Nano-silica sol, as
active material for advanced environmental protection coating, fire
protection and anti-corrosion coatings.
5. Powder processing on
the surface of the wall of the building.
6. In rubber, resin,
paint, unsaturated polyester reinforced polymer materials used as
fill material.
7. Additives of other
active areas.
