Heavy/Light Calcium Carbonate (CaCO3) Powder
Calcium carbonate is a chemical compound found in rocks in all parts of the world, and is the main component of shells of marine organisms, snails, coal balls, pearls, and eggshells. Calcium carbonate is the active ingredient in agricultural lime. It is commonly used medicinally as a calcium supplement.
Our calcium carbonate can be used in various fields due to its advantages such as low oil absorption rate, low wear value, virulent insipidity etc.
The usage fields nowadays include rubber-making, paper-making, paint, pharmacy, chemical fertilizer, feed, food, and sugaring, hygienic products.
In paper-making industry, by adding calcium carbonate, the paper can be whitened and easier to be written on;
In chemical fertilizer industry, calcium carbonate can be added as the addictive;
Calcium carbonate is also significant filler in plastic-making. Especially in the European countries, calcium carbonate takes up to 60% in the filler market. And it's widely used in making plasticized PVC to make the plastic softer and stronger;
In paint-making industry, calcium carbonate can increase the glossiness, aridity and the covering power...
