(instant sodium silicate, instant Water glass )
PV instant powdery sodium silicate series are even antifreezing white powdery materials; Molecular formula: Na2O.nSiO2.H2O The number of N is determined by specification and uses.
Developed by Zhejiang University and produced by our factory, PV instant powdery sodium silicate series are mainly used in kiln spray-fixing material, formless refractory materials, casting industry, warming material and adhesive of coating industry; moreover, it can be used as thickener in the drilling of petroleum, activator of flyash cement, or used as degreasing, dust-removing, filling and buffer of synthetic detergent, industrial cleaning agent and P-free washing powder, It also can be used in the application range of liquid water glass.
