Description
Technical field
The utility model prepares reaction kettle more particularly to a kind of efficient precipitated calcium carbonate.
Background technique
Precipitated calcium carbonate is made from chemical processes.Since its settling volume (2.4-2.8mL/g) ratio uses machine
The powdered whiting settling volume (1.1-1.9mL/g) of tool method production greatly, therefore referred to as precipitated calcium carbonate.Its chemical formula
For CaCO3, it reacts with all strong acid, generation and corresponding calcium salt (such as calcium chloride CaCl2), while releasing titanium dioxide
Carbon.Under room temperature (25 DEG C), the concentration product of precipitated calcium carbonate in water is 8.7/1029, solubility 0.0014；Lightweight carbonic acid
The pH value of calcium aqueous solution is 9.5~10.2；The pH value of saturation of the air precipitated calcium carbonate aqueous solution is 8.0~8.6；Precipitated calcium carbonate
It is nontoxic, odorless, nonirritant, it is usually white.
