Open Data Verified Data
Industrial sodium silicate has different properties due to the different ratio of sodium oxide to silica in the molecule. The molecular molar ratio of sodium oxide to silica is referred to as a modulus, and those with a modulus of 3 or more are referred to as neutral water glass, and those with a modulus of 3 or less are referred to as alkaline water glass. Its products are usually divided into solid water glass, hydrated water glass and liquid water glass. Sodium silicate is a colorless, pale yellow or cyan transparent viscous liquid. Soluble in water is alkaline. In case of acid decomposition and precipitation of colloidal precipitation of silicic acid, belonging to the vitreous body material, no fixed melting point, water treatment with a general modulus of 2. 5~3.0.

SODIUM SESQUISILICATE - Use
Open Data Verified Data
as a corrosion inhibitor, silicate was first used in the prevention of domestic water pipeline. After that, the composite formula with silicate as the main corrosion inhibitor was prepared by domestic and foreign researchers, which further improved the corrosion inhibition performance of silicate. Silicate can be on the clean metal surface, can also have rust on the metal surface to form a protective film, but these protective films are porous, so the use of silicate alone is poor corrosion inhibition, silicate often with polyphosphate, organic phosphate, molybdate, zinc salt and other corrosion inhibitors compound, synergistic effect. At present, the development and research of silicon composite agent has become a new development trend. Silicate can not only inhibit the corrosion of steel in cooling water, but also can inhibit the corrosion of non-ferrous metal-aluminum and copper and its alloys, lead, zinc coating, especially suitable for the control of brass. Silicates are effective in preventing CI-attack and can therefore be used in water make-up water or circulating water systems containing high Cl. There are circulating cooling water, the general use of silicate concentration of 40~60mg/L (Sioz), and low 25mg/L. The running pH value of Shengjia was 8.O -9.5. When silicate is used as a corrosion inhibitor, sufficient oxygen must be present in the cooling water for the metal to be effectively protected.

| classification | Sodium silicate is divided into two types, one is sodium metasilicate, chemical formula Na2SiO3, formula amount 122.00. Sodium metasilicate alias "disodium trioxysilicate",CAS number: 6834-92-0. The other is sodium orthosilicate (sodium orthosilicate), chemical formula Na4SiO4, relative molecular mass of 184.04. Sodium silicate is colorless crystals, melting point 1361K(1088 C), rare. Water Glass solution due to hydrolysis and alkaline (slightly stronger than soda ash). Because it is a weak acid salt, hydrochloric acid, sulfuric acid, nitric acid, carbon dioxide can precipitate silicic acid. Storage should be closely to prevent the entry of carbon dioxide, and should be used to prevent the use of rubber plugs to stick to the glass plug. Industrial commonly used soda ash and quartz eutectic preparation of Na2CO3 SiO2 → Na2SiO3 CO2, products often because of ferrous salt with light blue-green. It is used as an inorganic adhesive (which can be mixed with talc powder and the like), soap filler, acid-resistant concrete, and paint for external wall after adding pigment. It is poured into the soil of ancient building foundation to make the soil firm to prevent collapse. Sodium metasilicate is a low molecular weight Crystal prepared by the hydrothermal reaction of ordinary foam alkali and caustic soda. There are anhydrous, pentahydrate and nonahydrate, among which nonahydrate exists only in the market of China, it is an emergency product with low technical content that was developed in an urgent need of sodium metasilicate in the Eighties of the last century. Because its melting point is only 42 ℃, it can easily become liquid or paste when stored, and it is being gradually eliminated, but due to some user habits and some areas of crystal water is not very concerned about, sodium metasilicate nine water or have a certain market. |
