The mystery of sodium silicate
Sodium silicate, commonly known as pyrophorine or water glass, is a water-soluble silicate. Its chemical formula is usually Na2SiO3, but depending on the preparation method and use, sodium silicate may contain different amounts of crystal water to form a variety of hydrates. Sodium silicate is soluble in water and dilute lye, insoluble in alcohol and acid, and the aqueous solution is alkaline. This unique solubility has laid the foundation for the application of sodium silicate in many fields.
Sodium silicate comes in a variety of physical forms, which can be white powder, crystalline particles or viscous aqueous solutions. Its melting point is as high as 1088 ° C, and its density is about 2.4 g/cm ³. It is easy to absorb moisture in the air, with decontamination, emulsification, dispersion, wetting, permeability and PH buffer ability. These properties make sodium silicate exhibit excellent performance in many fields, such as detergents, preservatives, adhesives, fire retardants and water repellents.
Preparation process and technological innovation
The preparation methods of sodium silicate are mainly divided into the dry method (solid phase method) and the wet method (liquid phase method). The dry process usually involves the eutectosis of quartz sand with soda ash or caustic soda at high temperatures to produce sodium silicate. The wet rule is obtained by chemical reaction, such as the reaction of sodium silicate solution with sulfuric acid or hydrochloric acid, and then through neutralization, precipitation, filtration and other steps. In recent years, with the continuous progress of technology, the application of advanced processes such as spray drying has made the production of sodium silicate more efficient and environmentally friendly.
Extensive expansion of application fields
The applications of sodium silicate are vast, encompassing nearly all key industrial domains. In the construction industry, sodium silicate as a cement additive can significantly improve the impermeability, corrosion resistance and durability of concrete. In the paper industry, it is used as a sizing aid to enhance the strength and durability of paper and improve the smoothness of paper and printing adaptability. In the textile industry, sodium silicate is used as a degreasing, bleaching and fireproof treatment agent for textiles to improve the whiteness and gloss of fibers and enhance the dimensional stability of textiles.
In addition, sodium silicate has a wide range of applications in cleaning agent manufacturing, water treatment, foundry industry, oil extraction, wood treatment, ceramic and glass industry and agriculture. As one of the raw materials of synthetic detergent, sodium silicate can soften water quality, improve washing efficiency, and have a certain alkaline buffering effect. In sewage treatment, it can effectively remove the hardness ions in water, prevent the scale of water pipes and heat exchange systems, and has a certain bactericidal and algal killing function.
Comparative analysis with similar materials
Materials similar to sodium silicate include potassium silicate and lithium silicate. Potassium silicate is relatively more expensive but not as rich in water as sodium silicate. Anhydrous potassium silicate is hygroscopic and can absorb water to form non-absorbent potassium sesquisilicate, greatly reducing the tendency to crystallization is the use of a wide range of alkali metal silicates. Because of its high price, lithium silicate is mainly used as an inorganic binder in some high-grade inorganic building coatings.
In contrast, sodium silicate is widely used in various fields because of its large yield, low manufacturing cost and excellent performance. Although potassium silicate or lithium silicate may have superior properties in some specific applications, sodium silicate is still the material of choice in most industrial sectors considering cost, effectiveness and availability.
