Product Description
Dear sirs, We handle sodium metasilicate pentahydrate (prilled type) from 1996 until now. And we found this product from China is as good as other famous world brands. Please find all its features as follows: Character: High dissolution rate also in cold water, good-free flowability granules, high whiteness, negligible insoluble residue, high mechanical strength, low dust content. Appearance: white and free-flowing, well-distributed beads. Technical data: Total alkali content (based on Na2O) % 28.7+/- 0.7 Deoxide silicon content (based on SiO2) % 28.7+/- 0.7 Fe content % Max. 0.03 Whiteness % Min. 85 Weight loss (600 degrees C) % 43.0 +/- 1.0 PH (1% solution) 20 degrees C 12.5 +/- 0.1 Size distribution: -1250um 2%max, +180um 2%max Function and Alkalinity: The alkalinity provided by sodium Metasilicate saponifies fatty soil which makes them easy dissolvable, The high active alkali and minimum inactive alkali content makes sodium Metasilicate an economical choice for cleaning applications. Buttering action: it is very important to keep the PH value at a high and constant level throughout the cleaning process. Corrosion inhibitor.: by forming a protective barrel, the soluble silica content of sodium Metasilicate acts as a corrosion inhibitor and protests metal, glass and ceramic surfaces against alkaline attack from other detergent ingredients such as phosphates, synthetic detergents and other alkaline. Detergency properties: builder action, interfacial tension, Emulsification, Deflocculation and suspension of soils. Applications: machine dishwashing formulation formulations for households, heavy duty metal cleaning , milk can cleaner, heavy duty laundry detergent formulations, bleaching of paper, deflocculation of clays, ore flotation, water treatment, cotton yarn braising and boiling, etc.. We hope to exchange with you for more details. Best regards, Fan Li Wei (Mr.) President Luoyang Sincere Trading Co., Ltd
