This product acts as food additive. Nutrition enhancement, it act on during food processing,and it effect on loosing, calcium replenishment The product is widely used in industries of health Care products and Salt.Also can be used in Cigarette paper mill.
98%-102% calcium carbonate food grade
molecular formula: CaCO3
CAS: 471-34-1
Appearance: White powder
Properties:
White powder. Odourless and tasteless. Dew buy air. There is no change, a proportion of 2.710. Melting point 1339 &; ordm C. Almost insoluble in water in contain or ammonium trioxide iron water dissolves, insoluble in alcohol. Encounter dilute acetic acid, rare hydrochloric acid, nitric acid happen bubble boiling, thin and dissolve. Heating is decomposed into CaO (CaO) and carbon dioxide (CO 2).
Use:
According to the different crushing fineness, industry is divided into four different specifications: solo, sf, three fly, fly, respectively applied for every four industry.
