Analysis reagent-sodium silicate powder
What is sodium silicate?
There are two types sodium silicates: the chemical formula Na2SiO3, and the formula amount 122.00 is sodium metasilicate. The chemical formula Na4SiO4. Sodium silicate has a density 2.4g/cm3. It can be dissolved in water to make a viscous liquid, also known as water glass or bubble alkali. It acts as an organic glue. Solid sodium silicate is often called water glass in south and bubble alkali north. Water glass is the general name for sodium silicate aqueous solution. Pure sodium silicate, which is transparent and colorless, is the only kind of sodium silicate. However, the majority of sodium silicate that is sold on the market contains light-blue impurities. Sodium orthosilicate, a rare colorless crystal, has a melting temperature of 1291K (1088). Water glass solution is slightly alkaline from hydrolysis, which makes it slightly stronger than soda-ash. It is a weak acid sodium, so it can precipitate siliconic acid in the presence hydrochloric acid and sulfuric acid. Carbon dioxide should not be allowed to enter the container during storage. Rubber stoppers are used to stop ground glass stoppers adhering to each other. In industry, sodium carbonate is often combined with quartz to make Na2CO3+SiO2+CO2 These products have a light blue-green color because of ferrous salts. They can be mixed in with talcum powder and other organic bonding agents. They are used in soap fillers, acid-resistant concrete, and soap fillers. These pigments can be used for exterior wall coatings or poured into the foundation soil in ancient buildings to ensure that the soil is firm and resists collapse.
Preparation of sodium silicate granules
Sodium chloride method: Take sodium chloride (NaCl), and quartz sand (as raw materials), and mix the two together. Next, melt the quartz sand with sodium chloride and inject steam to make hydrochloric acid and sodium silicate. This method is not suitable for use in factories. It is slower in terms of reaction speed.
Use of sodium silicate dust
Analytical and flame retardants as well as adhesives. a. To increase the material's weather resistance, you can coat the surface. For porous materials, such as clay bricks and cement concrete, silicate concrete, or stone, soak the material in water glass with a density greater than 1.35g/cm. This will increase the material's strength, compactness and resistance to frost. Reinforce the soil. Add water glass and calcium chloride solution to the soil alternately using pressure. The generated silicic Acid gel is in an expansion state due to the soil's water absorption.
