High whitness silica
Using the high quality
silica sand , we grind it with vibrating to produce the High
whitness silica powder.the production has the feature of high
purity and whiteness, and its granules is very small( the
smallest can be above 1000mesh), meanwhile, its granules are
well-distributed. The production can be easily infiltrated
with different resin and blended, and it has the quality of
excellent adsorption. Its suspension is also remarkable , as a
result , it can eliminate or weaken sediment and
stratification. This type SiO2 has often be used in epoxy
potting compound,plastics and other stuffing, and it can also
be used in metallurgy,casting, ceramics and man-made marble
