Sodium Silicate Solution
widely used in detergent manufacturing, water treatment, cement and construction chemicals, refractory binders, foundry applications, paper manufacturing and industrial cleaning formulations.
Application & Uses
Major Applications
-
Detergent Manufacturing: Used as an alkaline builder, buffering agent and corrosion-inhibition component.
-
Water Treatment: Used in selected corrosion-control and water-treatment formulations.
-
Construction Chemicals: Used in cementitious systems, concrete treatment and chemical grouting.
-
Foundry Industry: Acts as an inorganic binder for sand moulds and cores.
-
Refractory Manufacturing: Used as a binder in refractory cements and heat-resistant materials.
-
Paper and Pulp Industry: Used in peroxide bleaching stabilization and selected processing applications.
-
Industrial Cleaning: Provides alkalinity and supports detergent action in suitable cleaning formulations.
Sodium Silicate is used in soaps detergents and in the manufacture of silica gel. It is used as a cement, binder, filler and adhesive. And also used as a wall coating, in concrete, fire proofing material and as a sealant. It is also used to preserve eggs and wood.
Dosage & Directions for Use
APPLICATION::
It's used in construction, detergents, textiles, and even food preservation.
Here's a more detailed look at its uses:
Construction:
Concrete and Cement Admixture:
- Sodium silicate increases the strength and durability of concrete and acts as a sealant, preventing water penetration.
Soil Stabilization:
- It's used to stabilize soil at construction sites, particularly for roads and foundations.
Fireproofing:
- Sodium silicate acts as a fire retardant, adding a layer of protection against fire damage to buildings.
Detergents:
Builder:
- It helps remove hard water ions and control alkalinity, making detergents more effective and preventing fabric damage.
Soap Manufacturing:
- Sodium silicate can be used as a filler and to increase the hardness of soap bars.
