Selling Calcium Carbonate In Surabaya

Calcium carbonate (Calcium Carbonate) is the chemical name of Limestone or Limestone, has the compound formula CaCO3, which means the elemental bond of Ca (Calcium / Calcium) with CO3 compounds (Carbonate).

The main uses of calcium carbonate in the construction industry, either as a building material or limestone aggregate for road construction or as a cement material. However, because weathering is mainly caused by acid rain, calcium carbonate in the form of limestone is no longer used for self-building purposes, but only as the main raw material for building materials.

Calcium carbonate is also used in the purification of iron from iron ore in blast furnaces. In the oil industry, calcium carbonate added to the drilling fluid as a formation-bridging and filter cake-sealing agent is also a material that increases the density of the drilling fluid to control downhole pressure.. Calcium carbonate is added to swimming pools, as a pH corrector to maintain alkalinity and compensate for the acidic properties of disinfectants.

In North America, calcium carbonate has started replacing kaolin in glossy paper production. Europe has adopted this as a base for paper making or acid-free papermaking for decades. PCC is used for filling paper and deposited and ready coating paper in various shapes and sizes having the characteristics of a narrow particle size distribution and a ball diameter equivalent to 0,4-3 micrometer.

Calcium carbonate widely used as an extender in paint, in certain emulsion matte paints where normally 30% the weight of the paint is either chalk or marble. It is also a popular filler in plastics. Some typical examples include around 15 to 20% loading of lime in unplasticized polyvinyl chloride (uPVC) drainage pipes, 5 to 15% lime coated or marble on uPVC window.

PVC cables can use calcium carbonate at loads up to 70 phr (parts per hundred parts of resin) to improve mechanical properties (tensile strength and elongation) and electrical properties (volume resistivity). Polypropylene compounds are often filled with calcium carbonate to increase rigidity, requirements that become important at high temperatures of use.

In terms of quality, Limestone or Calcium Carbonate has several quality parameters, namely Rate / CaCO3 content, Purity / Homogeneity and Hue (Whiteness Rate). In Indonesia, Limestone natural resources / Limestone or the chemical term Calcium Carbonate is very much and spreads in almost all parts of Indonesia, starting from Sumatra, Java, Borneo, Sulawesi to Papua.
