Application of Sodium Silicate in Water

  1. Construction industry: In the construction industry, sodium silicate formed by mixing with water has good adhesion and durability and is often used as building adhesive, waterproof coating, etc.
  2. Ceramic manufacturing: In ceramic manufacturing, Sodium Silicate mixed with water can be used as an additive in ceramic slurry, improving the hardness and heat resistance of ceramics.
  3. Glass manufacturing: In the glass manufacturing process, sodium silicate can be mixed with water as part of the raw glass material, improving the transparency and mechanical strength of the glass.

The evaluation of the quality and purity of the sodium silicate can be carried out through the following steps:

  1. Appearance inspection: Observe the appearance of the sodium silicate, which should be white or light yellow powder without clumping or impurities.
  2. Purity testing: Chemical analysis methods can be used to test the purity of sodium silicate. For example, titration, gravimetric and other methods can be used to determine the content of silicate ions in sodium silicate to determine its purity.
  3. Physical property testing: It can test the specific gravity, melting point, moisture absorption and other physical properties of sodium silicate to evaluate its quality and purity.
  4. Impurity content test: It can measure the impurity content in sodium silicate, such as the plasma content of iron, calcium, and magnesium, to evaluate its purity.

Performance and stability of Sodium Silicate

  1. Stability: Sodium silicate can exist stably over various temperature and pH conditions. This means it can maintain its chemical properties under various environmental conditions and is less prone to decomposition or deterioration.
  2. Corrosion resistance: Sodium silicate has excellent corrosion resistance and can react with many other substances. This makes sodium silicate an ideal choice in many industrial processes.
  3. Chemical reactivity: sodium silicate can be used as a catalyst, gel agent and solvent. Regarding catalysts, sodium silicate is widely used in preparing synthetic catalysts, such as metal oxide and silicate catalysts. In terms of gel agents, sodium silicate can form silicon gel. The gel is highly porous and widely used in catalyst support, separation materials and adsorbents. In addition, sodium silicate can also act as a solvent and mediator in various chemical reactions, promoting the progress of the reaction.
  4. Application of building materials: Sodium silicate can be used as a cement additive to facilitate the strength and durability of cement. In addition, sodium silicate can also react with calcium ions to form calcium silicate gel, filling the micro pores in concrete and improving its compactness and impermeability.

Sodium Silicate and Water Storage and Use

  1. Moisture-proof and moisture-proof: Sodium silicate is apt for moisture absorption and should be stored in a dry and ventilated place.
  2. Avoid contact with strong acids and bases: Sodium silicate is prone to chemical reactions in strong acid and alkali environments and should be avoided from contact.
  3. Pay attention to safety when using sodium silicate; safety precautions should be taken to avoid inhalation or contact with the skin.
