?2015 New Product of Heavy Calcium Carbonate/ Light Calcium Carbonate With Cheaper Price??
Introduction
?
TPS?is calcite powder is referred to as heavy calcium carbonate, is by natural carbonate minerals such as calcite, marble, limestone grinding and into. Is commonly used in powdered inorganic filler, has high chemical purity, inert, not easy to chemical reaction, heat good stability, in the decomposition of 400 DEG C or less will not, high whiteness, oil absorption rate and low refractive index low, soft, drying, does not contain water of crystallization, the low hardness wear value is small, non-toxic, tasteless, odorless, good dispersion. According to the need to provide different size requirements of ordinary coarse whiting powder, superfine heavy calcium carbonate, wet ultrafine grinding calcium carbonate, ultrafine surface change of heavy calcium carbonate.
?
State
?
White powder, colorless, tasteless. Stable in air. Almost insoluble in water, insoluble in alcohol. Dilute acetic acid, dilute hydrochloric acid, dilute nitric acid occurs in the boiling, and dissolved. Heating up to 898 C starts to break down into calcium oxide and carbon dioxide.
The shape of heavy calcium carbonate is irregular, the size of the particles is different, and the particles have some edges and corners, the surface is rough, the particle size distribution is wider, the particle size is larger, the average particle size is 1~10 M. Heavy calcium carbonate was divided into m (3 m), fine calcium carbonate (D 1~3), calcium carbonate (0 5~1 m).
Characteristics: irregular shape of A. particles; B. particle size distribution; C. particle size
?
Application
?
Calcium carbonate has been widely used in papermaking, plastics, plastic film, chemical fiber, rubber, adhesives, sealants, daily chemicals, cosmetics, building materials, coatings, paints, inks, sealants, sealing wax, putty, felt layer packaging, medicine, food, such as chewing gum, chocolate, feed, and its role is: increases the volume of the product, reduce the cost, improve processing performance (such as regulation of viscosity, rheological properties, vulcanization properties), to improve the dimensional stability, reinforcing or semi reinforcing, improve the printing performance, to improve the physical properties (such as heat resistance, extinction, resistance to wear, flame retardancy, whiteness and gloss).
