Taian stroke power supply sodium silicate water glass manufacturer

Sodium silicate (Na2SiO3), also known as sodium silicate, sodium silicate (xNa2O · ySiO2), a colorless, green or brown solid or viscous liquid. Sodium silicate is made of silica (quartz sand), soda (or alkaline earth) in the melting furnace melting Party, cooling crushing obtained, the fuel is coal, natural gas, coal gas can. Sodium silicate production process can be divided into two kinds of dry and wet method, generally used is dry production of solid sodium silicate, and then dissolve into the liquid sodium silicate required specifications, the conversion rate 1:2.5 . The raw materials for the production of sodium silicate quartz sand, soda ash, by mixing the two to the reflection kiln, after calcination melting furnace water quenching packaging is solid sodium silicate. Solid sodium silicate is conducive to transportation and storage. The solid sodium silicate at a certain temperature and pressure to melt into liquid is the liquid sodium silicate. No. EINECS 215-687-4 [1] sodium silicate use is very broad, almost across all sectors of the national economy. In the chemical system is used to make silica, silica, zeolite molecular sieves, sodium silicate, silica sol, layer of silicon and instant powdered sodium silicate, potassium and sodium silicate and other silicate products, silicon compound The basic raw material; in the light of washing powder, soap, detergent and other essential raw materials, but also the water softener to help Shen agents; for help dye, bleach and sizing in the textile industry; widely used in the machinery industry in casting, grinding wheel manufacturing and metal preservatives; for the manufacture of quick-drying cement, acid-proof cement waterproof oil, soil stabilizer, refractories and other in the construction industry; in agriculture Silicon fertilizer can be produced; in addition sodium silicate as an adhesive agent, widely used cardboard (corrugated) carton adhesive. Builders phosphorus pollution of water resources, currently being fully replaced, instead of phosphorus-based builders builders need to meet three main functions: demineralized water, the necessary basic and good anti-redeposition capability. The latest generation of non-phosphorus builders are crystalline layered sodium disilicate only achieve these three requirements, but also has fast exchange of calcium and magnesium dissolved in water, with a bleaching agent has good compatibility and ease of concentrate and other characteristics, and therefore It is currently the most promising non-phosphorus builders, but there is no major domestic production. Domestic demand is now imported from abroad, the import price of 10,000 yuan / ton. It is estimated that China's non-phosphorus builders annual domestic annual demand will reach 50 to 80 million tons. Crystalline layered sodium silicate has four different crystal structure (a-, b-, g-, d-), wherein anhydrous d-type d-Na2Si2O5 is ideal.
