Main uses of silicon powder


As an efficient active admixture, it can significantly improve concrete's strength, impermeability, frost resistance, and durability. The characteristics of silica fume concrete have received attention. Silica fume concrete is widely used in water conservancy, hydropower, construction, highway, and bridge projects. There are many methods for producing silicon powder from silicon blocks. Among them, Raymond, pair roller, disc grinding, and impact spinning methods have better effects and are widely used. The equipment used corresponds to the Raymond method, counter roller machine, disc mill (also known as a vertical mill), and impact spinning method. From the perspective of pulverization principles, the first three types of pulverization are extrusion pulverization, and the latter type is impact pulverization. From the standpoint of their structures, there are significant differences, each with its characteristics, advantages, and disadvantages.

Control the segregation and bleeding of concrete materials, reduce or avoid defects such as honeycomb, pitted surface, weak interlayer, crack, and milk skin in concrete. Improve the compressive strength of concrete. Experiments have shown that silica fume can significantly improve the strength of concrete. Improve concrete's durability, impermeability, frost resistance, abrasion resistance, and corrosion resistance. Improve the carbonization resistance of concrete. For reinforced concrete, adding silica fume unfairly can improve the bond strength between the matrix and the reinforcement, enhancing the support's corrosion resistanceidity and density of refractory materials and their high-temperature strength and thermal shock resistance. In the material industry, high-grade, high-performance, low-cement refractory castables and prefabricated parts have a service life of three times that of ordinary castables, a fire resistance increase of about 100 , and significant improvements in high-temperature strength and thermal shock resistance. It has been widely used in coke ovens, iron making, steel making, steel rolling, nonferrous metals, glass, ceramics, and power generation.
