Water glass (sodium silicate) is what?
Water glass (sodium silicate) is an aqueous solution of sodium silicate is known, commonly known as the north south, known as sodium silicate; water glass (sodium silicate) by carbonization and dehydration crystallization consolidation, and is very similar to lime. Water glass (sodium silicate) can speed hard carbon dioxide after casting, sand collapsibility, water glass (sodium silicate) limestone sand has been widely used in steel, has the advantages of reducing the difference between silicon glass and glass? The risk of the lung. Water glass (sodium silicate) modulus is an important parameter of water glass, generally between 1.5-3.5, sodium silicate (sodium silicate) modulus is big, solid water glass (sodium silicate) is difficult to dissolve in water, the more water content of silica, glass (sodium silicate) viscosity, easy decomposition hardening, bonding force increases.
What is the glass?
The common glass is a transparent solid material, cold as silicate nonmetalmaterials hardening without crystallization, the main ingredient is silica, widely used in building, used to have the wind insulation transparent, colored glass and glass, glass like solids maintain a particular shape, like that with gravity liquid effect of flow. The difference between the water glass and the glass is intuitive, water glass is a liquid cooled glass is solid; glass is made of silica as the main ingredient, water glass is solid water with quartz sand and sodium carbonate after high temperature leaching liquid produced by using sodium silicate as the main component.
Water glass is mainly used for acid resistant engineering.
Modified water glass (sodium silicate) mud acid is an important material in acid corrosion, is the main characteristics of acid resistance, temperature, density and anti permeability, low price and convenient use. Can be mixed into acid clay, acid resistant mortar and acid resistant concrete, suitable for all kinds of anti-corrosion engineering structure of chemical metallurgy, electric power, coal, textile and other departments, is spinning structure building and acid storage tank, acid, and acid resistant acid resistant floor surface masonry material.
1. in chemical system, it is used to make silica gel, white carbon black, zeolite molecular sieve, five sodium silicate, silica sol and other silicate products.
2. in the light industry is indispensable in washing powder, soap, detergent raw materials, but also water softener, settling agent;
3. in textile industry, it is used for dyeing, bleaching and sizing.
4. also used oil catalytic cracking catalyst, the silicon aluminum soap packing, corrugated paper, adhesive metal preservatives, water softener, detergent additives, mineral mining, waterproof and plugging, wood fire, food antiseptic and adhesive etc..
