First Grade Liquid Sodium Silicate High Purity

Production Process Overview   The production processes for first-grade Sodium Silicate are mainly divided into dry process and wet process categories, with the specific choice depending on raw materials, product modulus, and application scenarios. Nantong Mengya New Materials Technology Co., Ltd. employs a mature dry production process to manufacture high-quality first-grade Sodium Silicate, which is a very traditional and mainstream method, particularly suitable for producing solid water glass or high-modulus water glass.   Dry Production Process Flow   The dry process involves uniformly mixing quartz sand and sodium salts (mainly Na₂CO₃ and Na₂SO₄) and subjecting them to melting reaction at high temperatures around 1350–1500°C. Based on different raw materials, it is further divided into the soda ash method and the mirabilite method. The specific process is: quartz sand (SiO₂) and soda ash (Na₂CO₃) are mixed in precise proportions and sent to a reverberatory furnace for high-temperat…
