Product Description:
Silica powder for marble gel is a kind of inorganic non-metallic mineral functional powder material, which is made of natural high-white and high-purity quartz ore by fine processing such as color separation, acid leaching, flotation, magnetic separation, grinding and precision classification. It has good transparency, high whiteness, good fluidity, low oil absorption value, acid-base corrosion, high purity and high hardness.
Application:
It is widely used in various kinds of adhesive products such as marble glue, dry-hanging glue and epoxy glue. The marble glue made from silica powder produced by Haosen is transparent and yellowish. It has the advantages of slippery, delicate and easy to reconcile, high transparency of transparent glue solidified material, hard peeling, no flowing and no oil seepage. Deeply favored by the majority of users!
Main features:
1. Good transparency, high whiteness and even particle size distribution.
2. Low ion content, low conductivity, excellent electrical insulation.
3. Stable chemical properties, no reaction with any other substances except hydrofluoric acid and strong base.
4. Low oil absorption, low viscosity, good dispersibility and fluidity.
5. Acid and alkali resistance, high temperature resistance, good insulation performance.
6. High wear resistance, strong weather resistance, good mechanical performance.
