What is Sodium Silicate?
this material is made as a soluble alkaline substance. This substance was first discovered by a man named Van Helmont in 1640. In some cases, this solution is also known as glass water, which is also present in solid form. This material has the ability to be stable in alkaline and neutral solutions.
This material has many properties that make it used in many cases, the most important reason is its low cost. this material is known by various names such as met silicate, sodium silicate and in some cases liquefied petroleum gas, liquefied glass, E550, blue glass and water glass.
This material has an inorganic mineral or chemical composition that benefits from the chemical form of Na2SiO3. The molecular mass reported for this substance is 122.07 g / mol. This product is available in both liquid and solid forms with a density of 2.4 grams.
Let us get familiar with different forms of sodium silicate:
As you know, this material has different applications in different industries based on its residue and density. this material has interesting properties and the presence of positive sodium ions in its structure along with silicate polymer chains can distribute a negative charge in this material, which in some cases is used as a deflocculated and in some situations as a flocculent.
To take. this material is known in the mining industry as a silica dispersant based on flotation. This material is used in the ceramic tile industry as a soil lubricant, which delays reaching the dexiotropic point.
Specifications of sodium silicate in Iran’s silicate industries
this material is often in the form of a clear solid (granules) or white powder. Totally, sodium silicates in the Iranian silicate industry are produced in both solid (powder) and liquid forms. Since this product is used as a raw material in the production industries of other products, customers can, based on its application and efficiency, buy sodium silicate in powder, solid, liquid, water solution, etc. from the group of silicate industries.
It should be noted that the quality and high purity of the material produced, is very effective in the quality of other products that are made using it.
Iran Silicate Industries Group, the first producer of sodium silicate in the country, from the beginning of its work has always emphasized on improving the quality and purity of the produced material, and also tries to use the latest methods and modern equipment in the manufacture of its products.
Using up-to-date knowledge and application of new technologies, this company has been able to produce and provide high quality this material to customers. In fact, the credibility of the name of Iran Silicate Industries depends on the responsibility of this group towards its customers and the production of quality products.
What is the use of sodium silicate?
As mentioned at the beginning of the text, this material has many uses due to its unique structure. We will give a brief overview of the pervasive applications of sodium silicate.
- Its usage in detergents
- Use in the Casting industry
- Use of sodium silicate in the cardboard and carton industry: This option is considered as one of the most widely used uses of sodium silicate. The question may arise that despite adhesives such as dextrin, starch adhesives and PVA, etc., why is sodium silicate used? In answer to this question, we must say that in terms of performance, the above adhesives are more capable, but the reasonable price of sodium silicate makes it more widely used. Due to the popularity of this material, experts have added additives to sodium silicate, which makes it perform better.
- Use of sodium silicate in the construction and tunnel industry: The use of sodium silicate causes the cement to react faster to calcium and the formation and hardening operations are performed faster. When digging tunnels, they need to use a method to form cement blocks as quickly as possible, so they use injected cement to fill the gap between the tunnel wall and the cement blocks. this material accelerates the cement in this process.
What are the properties of sodium silicate?
this material is a widely used material in industrial, manufacturing and agricultural applications. It has several properties such as adhesion, disinfectant and gelatin. In the following, we will give a brief description of each of the properties of this product.
Adhesion: The adhesion of sodium silicate makes it useful in many manufacturing activities. This material is used to connect items such as paper and cardboard, corrugated sheets and paper cores, the production of paper napkins and towels as well as fiber drums.
Disinfectant: Ceramic tile manufacturers usually use this material as a disinfectant by adding it as a thin layer to ceramic products. This function can also be used in ceramics and green utensils.
Gelatin: this material is considered as a raw material for the artificial production of silica gel. It is still used as a strong desiccant
sodium silicate analysis
There is a need to analyze this substance when using chemicals. Regarding the analysis of sodium silicate, we must say that this substance exists in different compounds, including Na2O and SiO2, which is why sodium silicate derivatives have different chemical properties and properties. These substances dissolve in water in different amounts. It should be noted that this chemical does not react with acids and alcohol.
It dissolves in water to form an alkaline solution. It is stable against alkaline and neutral solutions. this material is formed in such a way that SiO2 silica is obtained in molten sodium carbonate. If people want to get sodium silicate alkali, they have to add some dry soda to the furnace when it melts, or else they have to melt the silica with soda first.
