What is sodium silicate?

The sodium silicate is in the form of sodium silicate solution, the southern part is called water glass, and the northern part is called silicate alkali. The aqueous solution of sodium silicate is commonly referred to as water glass, and sodium silicate is a colorless, slightly colored transparent or translucent viscous liquid in a system in which water is used as a dispersant. Solid sodium silicate is a colorless, slightly colored transparent or translucent glass block. The morphology is divided into liquid, solid, and water quenched. Theoretically, these substances are called "colloids."
Ordinary sodium silicate is slightly bluish blue or granular solid, which is a slightly colored transparent or translucent viscous liquid after dissolution at high temperature and pressure.

The purposes of using sodium silicate which using silica fume

The use of sodium silicate which using silica fume is very extensive, almost all parts of the national economy.

 Chemical systems are used to produce various types of silicate products such as silica gel, silica, zeolite molecular sieves, pentahydrate sodium metasilicate, silica sol, layer silicon and instant powdered sodium silicate, potassium sodium silicate, etc.

 The basic raw material of silicon compounds.

In economically developed countries, deep-processed products based on sodium silicate have grown to more than 50 species, some of which have been used in high-tech, precision, and cutting-edge technologies; in the light industry, they are indispensable raw materials for detergents such as detergents and soaps. ,

It is also a water softener, a sinking agent; used in the textile industry for dyeing, bleaching and sizing; in the machinery industry is widely used in casting, grinding wheel manufacturing and metal antiseptics, etc.; used in the construction industry for manufacturing quick drying Cement, acid-resistant cement waterproof oil, soil solidifying agent, refractories, etc.; can produce silicon fertilizer in agriculture; additionally used as silica-alumina catalyst for oil catalytic cracking, soap packing, corrugated paper adhesives, metal preservatives, water softeners, Detergent builders, refractories and ceramic raw materials, bleaching, dyeing and pulping of textiles, mine dressings, waterproofing, plugging, fire prevention of wood, food preservation and adhesives...
