Sodium silicate

Sodium Silicate Powder also named water glass powder or hydration sodium silicate.
Molecular Formula: Na2O·mSiO2·nH2O molecular weight: 280-350
Appearance: white uniform powder.
Usage: Sodium Silicate Powder is widely applied in metallurgy industry, electricity industry and building industry. It was used as binder for making fire-resistant material, industry cleaner and antiseptic. In detergent industry, soap industry, it is as anti-oil agent, filling agent and corrosion buffer. As the binder and high temperature filling agent, it is utilized refractory, core, casting, strengthen the force character and durability for cement as fast-drying material. As the filing-hole material and strengthen material, it is utilized in oil-exploitation, nature gas exploitation, tunnel. Sodium Silicate Powder can be as the application scope of liquid sodium silicate.
Brief Introduction: Sodium Silicate Powder was approved as Famous Brand Of Qingdao. We can produce it according to the requirements of customers, such like requirements for Modulus, Content, Al2O3, Fe2O3 and so on.
