English name：Sodium metasilicate Anhydrous
Formula：Na2SiO3
Molecular weight：122.1
CASNO.：6834-92-0
Physicochemical characteristics：White particles; Relative density: 1.0-1.3 ; Melting point: 1089℃. Non-toxic, tasteless, pollution-free, strong alkaline solution. Strong detergency and buffering ability. Easy soluble in water with good dispersiveness and emulsifying properties. It doesn’t dissolve in ethanol. It absorbs the moisture of the air and is deliquescent with carbon dioxide. It neutralizes acidic sewage and emulsifies fat and oils. It is effective for inorganic deflocculating and has a very strong corroding effect on metals.
Main usage：used as synthetic detergent, the best substitute for Sodium tripolyphosphate. Good cleaner for various metals, tableware and public health. Washing auxiliary detergent for food and dairy products processing equipment. Liquefaclent forclay dispersion. Emulsifier for fat and oil. Paper deinking agent. Widely used in the industry of textiles and ceramics, detergent, printing and dyeing, papermaking, electroplating, coal water slurry, concrete, and petroleum.
Product packing specification：Inner bag: PE plastic bag Outer bag: woven bag Net weight:25kg.
Storage and Delivery：Please store in a cool, dry and ventilated place. Keep products from being wet and avoid too much sun exposure during transportation.
