The use of solid water glass is very wide, covering almost all sectors of the national economy. In the chemical system, it is used to produce various silicate products such as silica gel, white carbon black, zeolite molecular sieve, sodium metasilicate pentahydrate, silica sol, layered silicon and instant powdered sodium silicate, potassium sodium silicate, etc. The basic raw material of silicon compounds. In economically developed countries, more than 50 types of deep-processing products using sodium silicate as raw materials have been developed, some of which have been used in high, precise, and cutting-edge technology fields; in light industry, they are indispensable raw materials for detergents such as washing powder and soap. It is also a water softener and sedimentation aid; used in the textile industry for dyeing, bleaching and sizing; widely used in casting, grinding wheel manufacturing and metal preservatives in the machinery industry; used in the construction industry to manufacture quick-drying Cement, acid-resistant cement, waterproof oil, soil curing agent, refractory materials, etc.; in agriculture, it can be used to produce silicon fertilizer; in addition, it can be used as a silica-aluminum catalyst for petroleum catalytic cracking, soap filler, corrugated paper adhesive, laboratory crucible and other high-temperature materials, Metal preservatives, water softeners, detergent additives, refractory materials and ceramic raw materials, textile bleaching, dyeing and sizing, mine beneficiation, waterproofing, leak-stopping, wood fire prevention, food preservation and adhesives, etc.

A. Paint the surface of solid water glass to improve its weathering resistance. Impregnate or paint clay bricks, cement concrete, silicate concrete, stone and other porous materials with water glass with a density of 1.35g/cm? to improve the material’s performance. Density, strength, impermeability, frost resistance and water resistance, etc.
B. Solid Sodium Silicate Reinforced Soil By alternately injecting water glass and calcium chloride solution into the soil, the generated silicic acid gel will be in a swelling state due to the absorption of moisture in the soil, and the soil will be consolidated.
C. The solid water glass is formulated with quick-setting waterproofing agent.
D. Repairing cracks in brick walls with solid water glass. After mixing water glass, granulated blast furnace slag powder, sand and sodium fluorosilicate in an appropriate proportion, they are directly pressed into the cracks in the brick wall, which can play a role in bonding and strengthening.
E. The solid water glass sodium silicate aqueous solution can be used as the outer surface of the fire door.
F. Solid water glass can be used to make acid-resistant mortar, which is used for the lining of furnaces. Physical and chemical properties
G. Preparation of silica gel from solid water glass Na2O·nSiO2
