Specificity:Magnesium carbonate, light white block and easily to crack; odourless; relative density 2.2 melting point 350℃; steady in air; when heated to 700℃, it may set out carbon dioxide; almost insoluble in water, when soluble in water, it may create light reactions, insoluble in ethanol; when solubled in dilute acid; it will set out bubbles.
Uses:Alkalizers, drying agent; colour fixatives; anticaking agents; bulking agents; acidity regulators.
Packing: It is packed with polytene bag as liner and cornpound plastic woven bag as the outer layer. The net weight of each bag is 25kg.
Storage and transport: Kept in tightly-closed containers, it should be stored in a dry and ventilative warehouse, kept away from moisture and hot, furthermore, it should be stored separately from poisonous substances. Handled with care, so as to avoid damage to bags.
