1.Performance
Sodium silicate is a non-toxic, odourless white powder or crystalline particles, soluble in water and insoluble in alcohol and acid. Sodium metasilicate is easily soluble in water and has the ability to decontaminate, emulsify, disperse, wet, penetrate and buffer PH value. Its strong alkalinity helps to remove acidic dirt and promotes saponification and emulsification of oils and fats. In particular, the buffering effect of sodium metasilicate is very strong, greatly superior to other alkaline additives.
Sodium metasilicate pentahydrate has the general characteristics of sodium silicate and sodium metasilicate, and has a certain calcium and magnesium ion binding capacity, especially for magnesium ions, the binding capacity is greater than 260mgMgCO2/g (35 ℃, 20min).
2.sodium silicate properties
Chemical formula for Na2SiO3, melting point 1088 ℃, density 2.4 g/cm. Sodium metasilicate is soluble in water, there are several hydrates.
Mix quartz and soda ash according to stoichiometry, co-melt at 1000-1350℃ to produce sodium metasilicate: the viscous aqueous solution of sodium metasilicate is called water glass, also known as effervescent soda ash, which can be used as antiseptic, detergent, adhesive, fireproofing and waterproofing agents.
3.Use
It is used as casting, grinding wheel manufacturing and metal antiseptic in mechanical industry. It is used in the construction industry for manufacturing quick-drying cement, acid-resistant cement, refractory materials, etc.; in the textile industry for dyeing and bleaching of primary yarn; in the mining industry for ore dressing, waterproofing and plugging; in the paper industry for pulp binder, etc.
What is chromium trioxide?Chromium trioxide, an inorganic compound with the chemical formula CrO3, is a dark red or dark purple crystalline powder, soluble in water, sulphuric acid, nitric acid, ethanol, ethyl ether, acetic acid, acetone, and is mainly used in the electroplating industry, the pharmaceutical industry, the printing industry, leather tanning and fabric mordanting.- What is automotive urea for cars?

- What is sulfamic acid and its uses?Sulfamic acid is a white crystalline solid, stable and non-hygroscopic. It is soluble in water and formamide and slightly soluble in methanol, ether, acetone and concentrated sulphuric acid. It is classified as a strong inorganic acid and is produced commercially from urea and fuming sulphuric acid.
- Hafnium oxide uses and its propertiesChromium oxide generally refers to chromium trioxide. Chromium trioxide, an inorganic compound with the chemical formula Cr₂O₃, is a green crystalline powder, insoluble in water, acid and alkali solutions, soluble in hot alkali metal bromate solutions, mainly used for coloring ceramics and enamel, but also used as an analytical reagent, catalyst.
- Role of sodium k12 dodecyl sulphateWhite or light yellow powder or liquid, slightly with grease odor. Easily soluble in water, can reduce the surface tension of aqueous solution and emulsify grease. Insensitive to alkali and hard water, good compatibility with anion and nonion. This product is combustible, irritating and sensitizing. It can be ignited by open fire and high heat. Heat decomposition releases toxic gas.
- What is Ethyl Alcohol?Ethyl Alcohol (Ethyl Alcohol), commonly known as alcohol, fire wine, is a kind of alcohol compounds, the chemical formula is C2H6O, the structure of the simple formula for CH3CH2OH or C2H5OH. ethanol combusts very well, it is commonly used as a fuel, solvent and disinfectant, etc., and is widely used in organic synthesis.
