Uses of metal silicon powder and silicon powder
Silicon ash, also known as silicon ash, is the smoke recycled during the production and development of metal silicon or ferroalloy products. Because the silicon dioxide content in silicon ash is very high and the particles are very fine, it is not only used in rubber. Paint industry, but also widely used in industries such as concrete! Silica smoke has volcanic ash activity.
Uses of metal silicon powder:
1. Control the segregation and water seepage of concrete structural materials to reduce or avoid defects such as honeycombs, pockmarks, thin layers, cracks and milk skin in concrete.
2. Improve the compressive strength of concrete. Experimental studies have shown that microsilica powder can greatly improve the strength of concrete in my country.
3. Improve the durability of concrete, improve the impermeability, frost resistance, wear resistance and corrosion resistance of concrete.
4. Improve the anti-carbonation development ability of concrete in my country. For reinforced concrete, adding silica powder can not only improve the bonding strength between the matrix and the steel bars, but also enhance the corrosion resistance of the steel bars.
5. Improve the fluidity and density of refractory materials, and improve the high temperature strength and thermal shock resistance of refractory materials.
An important point is that there is a big difference between the prices of silicon powder and metal silicon powder. The price of metal silicon powder is several times that of silicon powder.
