The use of water glass is very wide, almost throughout the national economy every department.
A, In the chemical system is used to manufacture silica gel, white carbon black, zeolite molecular sieve, pentahydrate sodium metasilicate, silica sol, layer silicon and instant powder sodium silicate, sodium potassium silicate and other silicate products, is the basic raw materials of silicon compounds.
B, In the developed countries, the deep processing series products with sodium silicate as raw material have been developed to more than 50 kinds, some of which have been applied in the field of high, fine and advanced science and technology;
C, In light industry, it is an indispensable raw material in laundry powder, soap and other detergents, as well as water softener and sink aid.
D, Used in textile industry for dyeing, bleaching and sizing;
E, It is widely used in casting, grinding wheel manufacturing and metal preservatives in the machinery industry.
F, In the construction industry for the manufacture of fast drying cement, acid-resistant cement waterproof oil, soil curing agent, refractory materials, etc. In agriculture, silicon fertilizer can be made;
G, In addition, it is used as petroleum catalytic cracking silicon and aluminum catalyst, soap filler, corrugated adhesive, laboratory crucible and other high temperature resistant materials, metal preservatives, water softener, detergent additives, refractory materials and ceramic raw materials, textile bleaching, dyeing and slurry, mineral processing, waterproof, plugging, wood fire prevention, food anticorrosion and adhesives.
