Several special advantages of micro silica fume
From the appearance point of view: micro silicon powder and micro silicon powder are divided in this way. Micro silicon powder is made of pure quartz powder by ultra-fine grinding process. It has good temperature resistance, low coefficient of thermal expansion, high thermal conductivity, high insulation, low expansion, stable chemical properties and high hardness. It has high whiteness, fine particles, reasonable force distribution, large specific surface area, excellent suspension performance and high purity It is widely used in coatings, paints, adhesives, silicone rubber, precision casting, high-grade ceramics, ordinary electrical appliances and high-voltage components. According to the use of silicon powder, it can be roughly divided into the following categories: Ordinary silicon powder, electrical silicon powder, electronic silicon powder series, ultra-fine quartz silicon powder, nano silicon powder, etc. its elements include Fe2O3, Al2O3, Cao, K2O, Na2O, MgO, C, etc.
Micro silica powder is widely used in high-performance concrete, super strong cement, refractory and other fields, mainly used in cement or concrete admixture to improve the performance of cement or concrete. It has super high strength and wear resistance, erosion resistance, corrosion resistance, permeability resistance, frost resistance and other early strength special concrete, especially in dams, large reservoirs, hydropower, seaports, railway bridges, high-speed highways and so on Super high rise buildings such as roads, airport runways and tunnels are widely used. At the same time, micro silicon powder is also used in the production of refractories and ceramic products to improve the strength and durability of products and the comprehensive performance.
