What is sodium metasilicate:
Sodium metasilicate is a salt of silicic acid, belongs to the inorganic salt products, molecular formula Na2SiO3-nH2O, is a non-toxic, tasteless, harmless white powder or crystalline particles Chemicalbook, easily soluble in water, insoluble in alcohols and acids, the aqueous solution is alkaline, put in the air is easy to absorb moisture and deliquescence, with de-scaling, emulsification, dispersal, wetting, penetration and buffering capacity of the PH value,. It is mainly used as analytical reagent, fabric fire retardant, adhesive, hardener, weight gainer, filler, also used in ore flotation and petroleum refining.
Characteristics of sodium metasilicate:
The form is divided into three kinds: liquid, solid and water quenching.
Ordinary sodium metasilicate is slightly light blue lumpy or granular solid, which is slightly coloured transparent or translucent viscous liquid after dissolving at high temperature and pressure.
Liquid sodium metasilicate is colourless, slightly coloured transparent or translucent viscous liquid.
Solid sodium metasilicate is colourless, slightly coloured transparent or translucent glass block.Characteristics of sodium metasilicate:
Application range of sodium metasilicate:
1,widely used in all kinds of washing industry as washing auxiliaries. In the washing industry, such as super-concentrated washing powder, washing liquid,
Laundry cream, dry cleaning agent, fibre bleach, fabric bleach and so on.
2,also used in a large number of metal surface cleaners, beer bottles, floating product solvent cleaner, the whole solution can be used as metal rust inhibitor, scale cleaner, electrical parts cleaner.It can be used as metal antirust agent, scale cleaner, cleaning agent for electric appliances, and detergent for food industry.
3,It can be used in ceramics as water reducing agent.
4,It can also be used as mud consistency adjusting agent and mud unconsolidating agent in crude oil and natural drilling and extracting engineering.
5,In the construction industry, it is used as the modulation of acid-resistant mortar, acid-resistant concrete and cement coagulant.
6,In papermaking industry, it can be used as adhesive, fee expenditure ink agent, paper surface treatment agent.
7,In the textile industry as printing and dyeing auxiliaries, fabric pretreatment agent.
8,can also be used as a filler for soap, detergent, egg preservative, and vegetation molecular sieve, silicic acid and fire prevention materials.
What is sodium metasilicate pentahydrate:
Sodium metasilicate pentahydrate, is an inorganic compound with molecular formula H10Na2O8Si, molecular weight 212.14, slightly green or white powder, transparent lump or viscous liquid. It is used in super concentrated laundry powder, detergent, metal cleaning agent, food industry detergent, also used in paper bleaching, cotton steaming, porcelain clay dispersion and so on.
Characteristics of sodium metasilicate pentahydrate:
Sodium metasilicate pentahydrate has the appearance of white granule, in which the ratio of silica and sodium oxide is about 1, the aqueous solution is alkaline after dissolved in water, non-toxic and tasteless. Compared with similar products, Zhongfa Sodium Metasilicate Pentahydrate has the characteristics of high whiteness, even granule, easily soluble in water, good fluidity, not easy to absorb moisture and not caking, melting point 72℃.
Sodium metasilicate pentahydrate is widely used in ceramics, industrial cleaning, detergents, construction, textile, printing and dyeing, papermaking, electroplating, casting, mineral processing, oil mining and many other fields.
1,Applied to all kinds of washing industry. It is used as filler of soap, low phosphorus, non-phosphorus laundry detergent, laundry detergent, dry cleaning agent, etc. It is also used in a large number of metal surface cleaning agents, and can be used as metal antirust agent, scale cleaning agent, and cleaning agent for electrical parts after full solubility.
2,in the ceramic industry, can increase the surface negative charge of inorganic clay particles, the use of charge repulsion effect in order to reduce the viscosity of ceramic slurry, increase the mobility, which in the ceramic injection moulding process can improve the efficiency and product quality.
3,adhesive industry as corrugated paper, cardboard, plywood, wood, packaging materials, refractory materials and construction materials, such as adhesives.
4,It is used in chemical industry to make silicate, silica gel, silica sol, molecular sieve, silica black and silica-aluminium catalyst.
5,It can also be used as mud consistency regulator and mud unconsolidating agent in crude oil and natural drilling control and extraction project.
6,It can be used in the construction industry as the accelerant for acid-resistant mortar, acid-resistant concrete and cement.
7,It can be used as adhesive, ink stripping agent of waste paper and surface treatment agent of paper in papermaking industry.
8,In the textile industry as printing and dyeing auxiliaries, fabric pretreatment agent, fabric bleaching agent.
