Sodium Metasilicate anhydrous (20 LB)
sodium metasilicate anhydrous ( not hydrated ) 100% pure unlike the grade in the market which is pentahydrate and only contian 50% active metasilicate
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 corrosion inhibiting properties of Sodium Metasilicate help protect both metal and non-metal surfaces.
Sodium Metasilicate granules are white and free-flowing. The product is characterized by: ■ high dissolution rate, even in cold water ■ negligible insoluble residue ■ high mechanical strength ■ low dust content Alkalinity The alkalinity provided by Metso Sodium Metasilicate Pentahydrate saponifies fatty soil which makes them readily dissolvable. The saponified fatty soil acts as a soap and contributes to the emulsification and removal of oily and greasy soil. The alkalinity also neutralizes acid soils, and breaks down protein and starch. The high active alkali and minimum inactive alkali content makes Sodium Metasilicate an economical choice for cleaning applications.
The table shows the active and inactive alkali content for common industrial alkalies. Buffering action It is very important to keep the pH at a high and constant level throughout the cleaning process. Acidic soils lower the pH of the cleaning solutions below that required for optimum cleaning by the surfactants and other ingredients. Sodium Metasilicate is an excellent buffer and the effect of acid soil is minimized. Compared to other alkalis, with the exception of sodium hydroxide, Sodium Metasilicate keeps the cleaning solution at constant pH over an extensive loading of acidic soil.
