Liquid sodium silicate

Process reaction in liquid phase:

Caustic soda, quartz sand and water are mixed in mixing tank, then the mixture is fed into a reactor, where steam is introduced. The reactant is liquid sodium silicate with its module lower than 3. The reaction is as following:

nSiO2+2NaOH图片3.jpg Na2O·nSiO2+H2O  

Liquid Sodium Silicate Production Line

Usage of Finished Product :

----Metal repair. Sodium silicate and magnesium silicate work together to form a thick slurry layer on metal surfaces such as mufflers, so as to achieve the role of repairing and protecting the metal surface;

----Car repair. Inject liquid sodium silicate into the center of automobile head parts, such as engines, and form a strong sealant after high temperature to repair the parts;

----Aquaculture. It can be used as an aquaculture hatching substrate for algae growth;

----Food preservation. Eggs kept fresh with liquid sodium silicate can be kept for 9 months;

----Wood processing. Wood treated with sodium silicate is more resistant to insects and has a stronger flame retardant effect;

----Concrete. Mixing sodium silicate with cement and sand will make the concrete dry faster, stronger, more resistant to water, acid and abrasion through chemical reaction;

----Used in the manufacture of quick-drying cement, acid-resistant cement, water-proof oil, soil curing agent, refractory materials; subway grouting, waterproofing, leak plugging, mine dressing, etc.;

----Sewage treatment. As wastewater treatment in sewage treatment plants. The water glass will precipitate the binding molecules and heavier pollutants and separate them from the water molecules to clean sewage;

----As detergent auxiliary and textile dye auxiliary.
