What is Ground calcium carbonate (CaCO3 )?
Description
Heavy calcium carbonate (referred to as heavy calcium) is ground from natural carbonate minerals such as calcite, marble, and limestone. It has a series of superior physical and chemical properties (especially physical properties), such as easy dispersibility, surface hydrophilicity , gloss and whiteness, low hardness, large filling amount, etc., Its application fields include papermaking, plastics, rubber, cables, paints and coatings, adhesives, sealants, daily chemicals, medicine, Feed and composite new calcium plastic materials. .
Chemical properties
White powder, colorless and odorless. Stable in air. Almost insoluble in water, insoluble in alcohol. In case of dilute acetic acid, dilute hydrochloric acid and dilute nitric acid, it will boil and dissolve. When heated to 898 ℃, it begins to decompose into calcium oxide and carbon dioxide. It is a commonly used powdery inorganic filler, with high chemical purity, high inertness, not easy to chemical reaction, good thermal stability, no decomposition under 400 ℃, high whiteness, low oil absorption, low refractive index, soft and dry. , Does not contain crystal water, low hardness, low wear value, non-toxic, tasteless, odorless, good dispersion and so on.
The Uses of Ground calcium carbonate (CaCO3 )
Heavy calcium is the most widely used filler and is widely used in coatings, inks, plastics, rubber, paper, cosmetics, chemicals, medicine and beverages and other industries.
Preparation
The production process of heavy calcium carbonate is mainly divided into dry method, wet method or combination of dry and wet method. The fine grinding and classification of the dry production process mainly include: 1) Ball mill-classifier multi-specification product system; 2) Raymond mill-vibration mill-classifier combined system; 3) Vertical stirring mill-classifier combined system; 4 ) Jet mill-classifier combined system.
