Powdered Instant Sodium Silicate CAS 1344-09-8 Sodium Silicate Powder

Light industry
In the light industry, sodium silicate is an indispensable raw material in detergents such as washing powder and soap, which can enhance the decontamination effect and improve the stability and storage of detergents. In addition, sodium silicate can be used as a water softener and sedimentation aid to help purify water.

Textile industry
In the textile industry, sodium silicate can be used as a dyeing assistant and bleaching agent, improving the stability and permeability of the dyeing solution and making the dyeing more uniform. In addition, sodium silicate can also be used as a sizing agent, improving the yarn's smoothness and permeability and making the sizing more firm.

Machinery Industry
In the mechanical industry, sodium silicate can be used as a sand core binder in casting, improving the sand core's strength and fire resistance and making casting more precise. In addition, sodium silicate can be used as an abrasive binder to manufacture grinding wheels, improving wear resistance and durability.

Agriculture
In agriculture, sodium silicate can be used as silicon fertilizer, improving crops' disease and insect resistance and stress resistance and crop quality and yield.

Achitechive
In the construction industry, sodium silicate can be used as a raw material for quick-drying cement, acid-resistant cement, waterproof oil, soil curing agents, and refractory materials, improving the durability and stability of buildings. In addition, sodium silicate can also be used as an adhesive for corrugated paper, improving the cardboard's strength and water resistance.

Other areas
In addition to the above application fields, sodium silicate is widely used in petroleum catalytic cracking, wood fire prevention, food preservation, adhesives, and other fields.

How to produce sodium silicate?
1. Sodium silicate Dry production
Dry production means that silica powder and soda ash are mixed proportionately and sent into a reverberatory furnace or an electric furnace for high-temperature melting to obtain sodium silicate products. Specific steps are as follows:
1. Grind silica powder into fine powder, and remove impurities like iron, aluminum, etc.
2. Grind soda ash into fine powder and mix it with silica powder in a certain proportion.
3. Put the mixture into the reverberatory or electric furnace, and melt it at a high temperature.
4. Cool the melt to obtain the sodium silicate product.
The benefit of dry production of sodium silicate lies in the fact that it is easy to do and no additional facilities like water treatment or waste acid recovery are needed for the production process, and the production price is very low. However, the drawback to dry production is the high energy consumption. It also is simple to generate an enormous amount of waste gas and leftovers, which have an environmental impact.
2.Sodium silicate Wet production
Wet production refers to the reaction of quartz sand with NaOH solution to obtain sodium solution containing silicic acid, and then through the steps of concentration, crystallization, dehydration, or acidification to obtain sodium silicate products. Specific steps are as follows:
1. Mix quartz sand with NaOH solution to react.
2. a sodium solution containing silicic acid is obtained after the reaction solution is filtered.
3. Concentrate the sodium solution to remove the water in it.
4. Put the concentrated solution into the crystallizer for crystallization.
5. Dehydrating or acidifying the crystallized crystals to obtain sodium silicate products.
The advantages of wet sodium silicate production are low energy consumption, recyclable by-product Na2CO3, and less environmental impact. However, the disadvantage of wet production is that the process is complicated, a large amount of water and chemical reagents are required, and more wastewater and waste acid are generated, which requires special treatment facilities.
