Paucine, also known as sodium silicate, is also an inorganic substance, the chemical formula is Na2SiO3, its aqueous solution is called water glass, colorless, green or brown solid or viscous liquid.
The production process can be divided into two kinds of dry method and wet method, dry process raw materials are mainly silica (quartz sand), soda ash, the market also has a small amount of sodium sulfate (also known as sodium powder or glauber's salt) instead of soda ash, to reduce the cost of raw materials, but because of its heavy pollution and the quality of the finished product is slightly poor (the finished product is cloudy, containing more impurities), At present, it is only used in a small number of small enterprises in Northwest China and Shandong, and this part of the industry accounts for about 8%-10%. The product directly produced by the dry process is solid pyrophorine, which can be heated and melted to obtain liquid pyrophorine. The raw materials of the wet process are silica (quartz sand) and caustic soda, and the pressure steaming reaction is carried out in the high-pressure steamer to directly generate liquid water glass. At present, the process used in the domestic market is usually dry production of solid phaloid alkali, and then dissolved into the required specifications of liquid phaloid alkali.
1, in the chemical system is used to produce silica gel, white carbon black, zeolite molecular sieve, sodium metasilicate, silica sol, layer silicon and instant powdery foam alkali, potassium sodium silicate and other silicate products, is the basic raw materials of silicon compounds.
2, in the light industry, it is an indispensable raw material in laundry detergent, soap and other detergents, and it is also a water softener and a settling agent.
3, used in the textile industry for dyeing, bleaching and sizing; It is widely used in the machinery industry for casting, grinding wheel manufacturing and metal preservatives.
4, used in the construction industry for the manufacture of fast drying cement, acid-resistant cement and waterproof oil, soil curing agent, refractory materials, etc.
5, in agriculture can produce silicon fertilizer.
6, as an adhesive, it is widely used in the adhesive of cardboard (corrugated paper) carton.
China's production capacity distribution is greatly affected by the distribution of upstream raw materials and downstream industries, and its production capacity is mainly distributed in Shandong, Anhui, Hebei, Jiangsu and Zhejiang regions. The raw material soda ash used in the industry is mostly light alkali. Although the heavy soda ash has the advantages of greater ratio, less dust in the production process, and less loss to the kiln, the price of heavy soda ash is usually higher than that of light soda ash, and the profit of the caustic soda industry itself is lower, so most enterprises choose to use light soda ash. It is estimated that about 0.4 tons of light soda ash is consumed for every 1 ton of solid paucine produced.
Shandong Desen Lai by-product soda ash content is relatively stable, welcome new and old friends to discuss cooperation matters, our company will be in line with the "customer first choice" purpose, to provide you with quality service.
