Detailed introduction

Heavy calcium carbonate

Heavy calcium carbonate, or heavy calcium for short, is made from the grinding of natural carbonate minerals such as calcite, marble and limestone. Powdery inorganic filler is commonly used, with high chemical purity, inertia, not easy chemical reaction, good thermal stability, under 400℃ will not be decomposable, high whiteness, low oil absorption rate, low refractive index, soft, dry, does not contain crystal water, low hardness, low wear value, non-toxic, tasteless, odorless, good dispersion and other advantages.

Properties: white powder, colorless, tasteless, stable in the air. Almost insoluble in water, insoluble in alcohols. In case of dilute acetic acid, dilute hydrochloric acid, dilute nitric acid bubble boiling, and dissolve. Heated to 808 ° C, it begins to decompose into calcium oxide and carbon dioxide.

Characteristics: stable chemical properties, no change in the air, almost insoluble in water. Dense crystal structure, less impurities, smooth surface, uniform particle size, good processing performance, low DOP oil absorption value.

Application: Used in papermaking industry, with the characteristics of increasing surface gloss, improving whiteness, improving paper surface smoothness, etc.

When used in plastic composites, the bonding strength and mechanical properties of the interface of plastic composites can be improved obviously. It can be used to toughen, strengthen, improve luster and improve quality in various plastic pipes, profiles, plastic products, degradable plastics and wire and cable materials.

In the aspect of coating, the product and titanium dioxide according to a certain proportion of use at the same time, can make titanium dioxide more effectively play its hiding performance, reduce the amount of titanium dioxide, especially suitable for automotive paint, high-grade exterior wall coating use. At the same time, the powder resistance was significantly improved.

Used in the rubber industry, can improve the product's tensile, tensile, heat resistance, aging resistance, tear resistance and other properties.

Used in the coating industry, can increase the thickness of the coating, improve the wear resistance and weather resistance of the coating, and improve the powder coating rate and spraying area, in addition, it does not contain heavy metals, is not containing heavy metal powder coating of choice filler.
