Solid sodium silicate is usually packaged in woven bags or paper bags, lined with plastic bags, and stored in a dry and ventilated warehouse to avoid moisture and rain, prevent clumping and deterioration. The shelf life is generally about two year, and the product quality should be checked regularly during storage.
1. Casting industry: As a binder used in the production of molding sand and core sand, it can improve the strength, hardness, and breathability of sand molds, make the surface of castings smooth and the size precise, reduce scrap rates, and improve production efficiency and casting quality.
2. Paper industry: Used for paper sizing, it can improve the strength, water resistance, and glossiness of paper, enhance the printing and writing performance of paper, and also serve as a preservative and adhesive in the paper processing.
3. Building materials field: Adding an appropriate amount of sodium silicate to cement can improve its impermeability, water resistance, and strength, and is used to produce special cement such as fast hardening cement and acid resistant cement; In architectural coatings, it can be used as a binder and thickener to enhance the adhesion and durability of the coating; It can also be used to manufacture refractory materials, insulation materials, etc., such as refractory castables made by mixing sodium silicate with refractory aggregates, which have good high temperature resistance.
4. Detergent industry: It can be used as a detergent aid in combination with other surfactants to reduce water hardness, enhance washing effectiveness, prevent dirt from re depositing, improve detergent cleaning ability and stability, and also has a certain buffering effect to maintain the appropriate pH value of the washing solution.
Textile printing and dyeing industry: used as a fabric sizing agent to give yarns good wear resistance and smoothness, improving the strength and weaveability of fabrics; In the printing and dyeing process, it can be used as a mordant and fixing agent to improve the adhesion and color fastness of dyes, making the printing and dyeing effect more vivid and lasting.
5. Other applications: Used as a flotation agent in the mining industry, as a flocculant and precipitant in wastewater treatment, and as a rust inhibitor and cleaning agent in metal surface treatment.
