Sodium metasilicate, a very corrosive compound, is precipitated by acids and alkaline earth and heavy metal ions. When heated or acidified, solutions of the compound are hydrolyzed to free sodium ions and silicic acid. Sodium metasilicate is produced by the fusion of sodium carbonate with silicon dioxide or silica sand at about 1400 °C.

of soluble silica and alkali in Metso Sodium Metasilicate Pentahydrate reduces the interfacial tension more than alkali alone. This means that the cleaning performance of the surfactant system is enhanced and that oily and fatty soils are easier removed. Metso Sodium Metasilicate Pentahydrate also contributes to the wetting action of the cleaning
Sodium silicate is a generic name for chemical compounds with the formula Na 2x Si y O 2y+x or (Na 2 O) x · (SiO 2) y, such as sodium metasilicate Na 2 SiO 3, sodium orthosilicate Na 4 SiO 4, and sodium pyrosilicate Na 6 Si 2 O 7. The anions are often polymeric. These compounds are generally colorless transparent solids or white powders, and ...
Sodium metasilicate is an odourless white powder which forms highly alkaline solutions when dissolved with water. Sodium Metasilicate is largely used in the manufacture of soaps and detergents where it works to increase the cleaning efficiency of the surfactant products by reducing the hardness of water. Along with aiding the softening of water,
A new procedure has been developed, which is based on homogeneous precipitation of organized mesoporous silica from an aqueous solution of sodium metasilicate and a nonionic poly(ethylene oxide) surfactant serving as a structure-directing agent.
A well-known member of this series is sodium metasilicate, Na2SiO3. Also known as waterglass or liquid glass, these materials are available in aqueous solution and in solid form.
Is an inaccurate method to determine cleaner activity if dominant cleaning mechanism is surfactant removal of oil but not alkaline hydrolysis of oil. Measurement of the total ionic content in a feed (i.e., sodium metasilicate & other salts) Does not measure surfactant activity or distinguish effectively between free and total alkalinity.
Specifically, by a method such as dipping, wiping, or spraying, an aqueous solution of sodium metasilicate containing at least 0.01 mg/g, preferably 0.06 mg/g, is brought into contact with a subject such as a medical instrument, a breeding cage, or animal feces at normal temperature for at least one minute, preferably about 10 minutes.
The precipitation of solid particles from a homogeneous water solution of sodium metasilicate and surfactant blend was achieved by lowering the pH due to the hydrolysis of ethyl acetate added.
May 01, 2002 · Mechanism of oleate interaction on salt-type minerals, Part II. Adsorption and electrokinetic studies of apatite in the presence of sodium oleate and sodium metasilicate. International Journal of Mineral Processing 1990, 28 (1-2), 59-79. DOI: 10.1016/0301-7516(90)90027-V.
Oct 17, 2014 · The basic mechanism is as follows: STTP + heat → lower pH → loss of silicates in solution → corrosion Sodium tripolyphosphate (STTP) is an alkalinity builder constituent, and over time with heat in a hydrolysis reaction, it releases free acid. The free acid release lowers the solution pH.
A surfactant is the most important part of any cleaning agent. The word surfactant is short for "Surface Active Agent." In general, they are chemicals that, when dissolved in water or another solvent, orient themselves at the interface (boundary) between the liquid and a solid (the dirt we are removing), and modify the properties of the interface.
Itis a high content anionic surfactant with properties of detergency, moistening, foaming, impulsivity, and dispersity. The biological degradability of the product is more than 90%.
Dec 04, 2009 · A. Sodium metasilicate is not a cleaning agent by itself. It is a VERY strong base. The pH of a 1% aqueous solution is about 13. In moist air it is corrosive to metals like zinc, aluminium, tin and lead, forming hydrogen gas. As a strong base, it reacts violently with acids.
The hydration mechanism of geopolymer formed by sodium silicate activation of GBFS is via sodium metasilicate hydrolysis, cleavage of glassy network structure, formation of new gels of geopolymer and SCH, as well as generations of new mineral phases through aluminosilicate oligomers reacting with Ca 2 + and Na + ions under OH − catalysis.
Nov 10, 2018 · Depletion of high-grade resources has necessitated the use of low-grade fines, which contain good amount of mineral values and also liberate in finer sizes. Froth flotation, a physico-chemical surface-based process, is the most established solution, both technologically and economically, compared to other alternatives for fines beneficiation. For a successful and effective flotation ...

38, Its mechanism is to reduce the surface tension of solution, to enhance the efficiency of nebulization, to generate glue group of chemical combination and to concentrate molybdenum by surfactant. 39, Reverse micelle is a hydrous polymer that has a contrary structure to the normal micelle, it is formed by surfactant solving in non-polar solvent.
Jun 21, 2020 · Sodium Metasilicate provides both silica and alkalinity in a molar ratio of 1:1 between silica and sodium oxide, which makes it especially suitable for hard surface cleaning. Its multifunctional cleaning properties enhance the removal of fatty and particulate soil in both soft and hard water.

The metasilicate apparently provides some water softening capacity so the solution is effective in hard water (which I have). Oxyclean free is cheap, yes, but has fillers and probably surfactants and foaming agents which I would rather not have.
Sodium metasilicate is a member of the sodium compound family, according to the International Programme on Chemical Safety 1 2. A very basic compound, sodium metasilicate is used in a variety of industrial and household settings 2. While it is a cleaning and de-rusting solution, it is highly corrosive and should be handled with care.
The stability of a sodium silicate solution depends to a large extent on pH. All sodium silicate solutions will polymerize to form a silica gel when the pH value is reduced below 10. Reaction with acids (sol and gel formation) Sodium silicates react with acidic compounds. When solutions of relatively high concentrations are
61% Sodium percarbonate/carbonate - main cleaning agent 30% TSP/90 (Sodium Metasilicate) - lowers pH/caustic 5% EDTA - chelator 4% SDS/SLS - surfactant I don't necessarily need the chelator as I've never had the spotting problems, but I would like to have a relatively low foaming surfactant in the solution.
