Sodium fluorosilicate-water glass curing agent

Water glass materials are widely used in chemical and building corrosion protection. If we want the water glass material to cure in a short period of time and have a certain strength, we need to add a certain amount of curing agent. Sodium fluorosilicate is a traditional water glass curing agent.

The proportion of sodium fluorosilicate added directly affects the quality of water glass materials. If the amount of blending is too small, the solidification of the material is slow and the strength is low; if the amount of blending is too large, the setting hardening is too fast, the construction operation is inconvenient, and the early strength after hardening is high, but the late strength is remarkably lowered. The amount of sodium fluorosilicate is generally 12%-15%, and we should adjust it according to the temperature, humidity, modulus of water glass, density, etc. within the above range. The temperature is high, the modulus is large, and the lower limit is selected when the density is low; when the temperature is low, the modulus is small, and the density is large, the upper limit is selected.
