    Uses
    It has strong alkalinity, strong decontamination, strong cushioning capacity, can neutralize acidic dirt, emulsify fats and oils, reverse flocculation for inorganic substances, and anti-corrosion for metals. be used instead of sodium tripolyphosphate to synthesize high-efficiency detergent and metal detergent to reduce environmental pollution caused by sodium tripolyphosphate. Widely used in the configuration of various detergents, metal surface treatment, ceramic grinding aids, refractory raw materials, plastic water retaining agent raw materials, deoiling textile printing and dyeing auxiliaries and paper deinking agents.
    Features

    Anhydrous sodium metasilicate is a kind of inorganic white powder or crystalline granule, which is non-toxic, tasteless and environmentally safe. It is soluble in water, insoluble in alcoholic or acid-producing alkaline solutions, and very easy to absorb moisture when reacting with carbon dioxide and water in the air. It has the functions of descaling, emulsifying, dispersing, wetting and penetrating. It also has the function of buffer pH value. The PH value is about 12.4, the melting point is 1089 C, the apparent density is 0.8-1.3g/cm, and the appearance is white flowing crystal particles or powder.
