Instant sodium silicate is a white powdery material, which can be quickly dissolved in water. It is a special bubble alkali with cold resistance, uniformity, and extremely convenient use, transportation and storage. Instant powdered sodium silicate products also have all the properties and applications of liquid bubble alkali. Its molecular formula is Na2 · nsio2 · H2O, depending on different specifications and uses.

Applications of Powdered Instant Sodium Silicate:

1. It is used as an activator for fly ash cement to improve the activity of fly ash, thereby improving the compressive strength and flexural strength of fly ash admixture cement; or increasing the amount of fly ash in cement, thereby increasing the Cement production and lower cement production costs. Powdered instant sodium silicate can also be used as quick-drying agent and reinforcing agent for ordinary cement.
2. Used as drilling cuttings coagulation agent and shale anti-swelling agent for silicon-based drilling fluids, bentonite slurry cemented leakage plugging agent and colloidal cement leakage plugging agent, precipitation chemical water plugging agent for oil and gas wells, and oil and gas well swelling agent Type water blocking agent.
3. It is used as a binder for unshaped refractory materials such as kiln gunning material, castable, acid-resistant cement, etc.; a mixture of foundry industry, ceramic industry, paint industry and thermal insulation material; thickener in oil production industry.
4. Used as detergent aid in synthetic detergent; It is suitable for preparing low phosphorus and non phosphorus washing powder, replacing sodium tripolyphosphate, especially for the production of agglomerated concentrated washing powder; It is also suitable for making industrial detergents and other household detergents for various purposes.

Storage Condition of Powdered Instant Sodium Silicate:

The sodium silicate powder should store in a dry and cool environment in a sealed place, not exposed to the air, to prevent oxidative agglomeration caused by moisture, affecting the dispersion performance and use effect;
