Silica fume silica powder

What is silica powder?

Silicon powder, also called micro silicon powder, scientific name silica fume, is an industrial electric furnace that smelts industrial silicon and ferrosilicon at high temperatures, with the exhaust gas escape of dust through a unique collection device collection and treatment. In the escaped dust, the content of SiO2 accounts for about 90% of the total dust, the particle size is tiny, and the average particle size is almost nanometer level, so it is called silicon powder. Silica powder is an efficient active admixture that can significantly improve concrete's strength, impermeability, frost resistance, and durability. The characteristic of silica fume concrete has been paid more and more attention to. Silica fume concrete is widely used in water conservancy, hydropower, construction, highway, and bridge engineering.

 

Properties of silica powder

It can reduce the peak exothermic temperature of epoxy resin curing reaction and reduce the fixed substance's linear expansion coefficient and shrinkage rate to eliminate the cured importance's internal stress and prevent cracking. Sound insulation: Due to the high purity of silicon powder, low impurity content, stable performance, and excellent electrical insulation, the cured material has good insulation performance and arc resistance. Corrosion resistance: silicon powder is not easy to react with other substances, and in most acid and alkali chemical reactions, its particles are uniformly covered on the object's surface, with strong corrosion resistance. Reasonable particle distribution use can reduce and eliminate precipitation stratification phenomenon; It can enhance the tensile and compressive strength of the curing material, improve the wear resistance, increase the thermal conductivity of the curing material, and increase the flame retardant property. The silicon powder treated by silane coupling agent has good wettability to various resins, good adsorption performance, easy mixing, and no clumping phenomenon. As a filler, silicon powder is added to the organic resin, which not only improves the properties of the cured material but also reduces the cost of the product.

 

Is silicon powder harmful to the body?

Silicon powder, the body's most significant harm, is caused by silicosis due to long-term inhalation of large silica (Si02) dust. The dust enters the respiratory tract and is swallowed by lung macrophages, releasing active factors that stimulate fibroblasts to make more collagen.

 

Price of Silicon powder

Silicon powder particle size and purity will affect the product's Price, and the purchase volume can also affect the cost of Silicon powder. A large amount of large amount will be lower. The Price of Silicon powder is on our company's official website.
