Water glass is widely used in almost all sectors of the national economy.In the chemical system is used to manufacture silica gel, silica, 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 material of silicon compounds.In economically developed countries, sodium silicate as raw material for the deep processing series of products has developed to more than 50 kinds, some have been applied in the field of high, fine, cutting-edge science and technology;In the light industry is detergent powder, soap and other indispensable raw materials, but also water softener, sink agent;Used in the textile industry for dyeing, bleaching and sizing;In the machinery industry widely used in casting, grinding wheel manufacturing and metal preservatives;In the construction industry for the manufacture of fast drying cement, acid cement waterproof oil, soil hardener, refractory materials;Silicon fertilizer can be produced in agriculture;Also used as oil catalytic cracking of silica alumina catalyst packing, corrugated paper, adhesive, soap, laboratory crucible, high temperature resistant material, metal preservatives, water softeners, detergent additives, refractory and ceramic raw materials, textile bleaching, dyeing, and pulp, mining beneficiation, waterproof, plugging, wood fire, food preservative and adhesive, etc.
