Sodium silicate is mainly utilized as a raw material for adhesives, silica gel as well as silica, as a filler in the soap sector and also as a rubber waterproofing agent. Its use is really comprehensive, almost in all sectors and also fields.

Chemical Sector

1. Used as refractory binder, heater gunning representative, welding pole powder binder. Acid-resistant cement binder, degreasing help in detergent, pore blocking agent as well as reinforcing agent for oil expedition as well as tunnels.

2. Additionally made use of in paper lightening, mineral flotation protection, artificial detergents. It is a component of inorganic finishes and also a basic material for silicon series products such as silica gel, molecular sieve, as well as precipitated silica.

3. In the chemical system, it is made use of to manufacture various silicate products such as silica gel, white carbon black, zeolite molecular filter, salt metasilicate pentahydrate, silica sol, layered silicon as well as instant powdered salt silicate, potassium sodium silicate, and so on. Fundamental resources for silicon compounds.

4. In financially established nations, there are more than 50 sort of deep-processing items utilizing sodium silicate as raw material, a few of which have actually been used in high, precise and also cutting-edge science and also modern technology areas.

Light market, textile and also various other markets

1. In the light sector, it is an essential resources for cleaning agents such as cleaning powder and soap, along with a water softener as well as a sedimentation aid.

2. Used in dyeing, bleaching as well as sizing in the textile sector.

3. It is widely utilized in casting, grinding wheel production and also metal rust prevention in the machinery sector.

4. In the building and construction industry, it is utilized to make quick-drying cement, acid-resistant concrete waterproof oil, dirt treating agent, refractory materials, and so on.

5. In agriculture, it can be used to make siliceous fertilizers.

Sodium Silicate Properties

Sodium silicate is a water-soluble silicate, and its aqueous solution is called water glass, which is a mineral binder.

The relative density is 2.40, the melting point is 1088°C, and the refractive index (glass) is 1.520 (25°C). Soluble in water, decomposed in hot water, and precipitated silica gel.

The composition of industrial products is complex, which can be expressed as xNa2O·ySiO2. It is hygroscopic and is colorless, blue-green, brown solid or viscous liquid. Its physical properties vary with the ratio of sodium oxide to silicon dioxide. The aqueous solution is strongly alkaline.

Widely used in ordinary casting, precision casting, papermaking, ceramics, clay, mineral processing, kaolin, washing and many other fields.

Physical Properties

Impurities such as Fe2O3, CaO, MgO and Al2O3 contained in sodium silicate solution (water glass) have influence on its transparency and physical and chemical properties. The performance parameters of its aqueous solution include modulus n (molar ratio of silicon oxide to sodium oxide), density D (or Baume degree °Bé) and viscosity μ.

Chemical Properties

Hydrolyzed water glass is a strong base and weak acid salt, which reacts with water and hydrolyzes to form sodium hydroxide, thus making the water glass solution alkaline. The water glass solution is a colloidal solution whose colloidal particles are negatively charged.

Reaction with acid The water glass solution is alkaline, so it can react with inorganic and organic acids. As a result of the reaction, the silica sol was precipitated as a gel.

Reaction with alkali: The reaction with alkali metal ions only increases the alkalinity and reduces the modulus, but will not affect the stability of the water glass colloid solution. Reacts with alkaline earth metal ions to flocculate, resulting in a white gel precipitate.

Hardening of liquid water glass Liquid water glass reacts with carbon dioxide in the air to form amorphous silicic acid, which gradually dries and hardens, similar to the condensation hardening of lime.
