1. Aranthaangi Chemical Products Limited (ACPL): Calcium carbonate is a widely available chemical material that is most commonly found in rocks across the world. For its universal presence, it is generally called as “ubiquitous material.” It is said that over 4 per cent of the overall earth’s crust is comprised of this component. This is a very useful materials and is one among the most versatile materials known to mankind. Shells of marine organisms, coal balls, pearls, snails, etc contain this component. Formation of calcium carbonate involves two main raw materials – calcium ions and carbonate ions. When these two react with each other, the end product, calcium carbonate is formed. The primitive use of this component is for medical purposes, especially as calcium supplement. Or, it may be used as antacid. It is to be noted that excessive consumption of the component is harmful. Most common forms of this component are limestone, marble and chalk. All the three forms are identical in terms of their chemical components; however, they differ from each other in the level of purity, thickness, homogeneity, etc. How is it produced? Calcium carbonate used in industries is usually extracted by mining or quarrying. When there is a need to produce pure calcium carbonate, it is extracted from marble. On the other 2. hand, it is manufactured by passing carbon dioxide into a solution of calcium hydroxide. In this method, calcium carbonate is extracted in its precipitated form which is called Precipitated Calcium Carbonate (PCC). Properties of PCC: Here are the properties of the Precipitated Calcium Carbonate in India: It has a very fine structure with controlled particle size It is of the order of 2 microns in diameter This is used to produce paper The other form of this product is Ground Calcium Carbonate (GCC). As the name indicates, it is the crushed form of calcium carbonate. GCC is produced by crushing and processing the limestone to obtain the powdered form of the component. This is used for many industrial and pharmaceutical purposes. One of the main manufacturers of PCC in India is Aranthaangi Chemical Products Limited. 3. Uses of PCC: PCC is used for various purposes. Here is a brief list of its major applications: It is used in construction industry as a building material Used as limestoge aggregate for road building This is a basic ingredient for manufacturing cement The builders lime used for burning in kiln is manufactured using calcium carbonate Calcium carbonate is used in purifying iron from iron ore It is used as weighing material. It helps in increasing the density of drilling fluids that in turn helps in controlling down hole pressure It is used in swimming pools for correcting the pH levels and to maintain alkalinity of water 4. CaCO3 is the raw material for sugar refining from sugar beet As known to most people, in general, it is used as a major component in manufacturing blackboard chalk Aiming at reducing the overall production cost, calcium carbonate is used for manufacturing latex gloves It is used in micro-porous films in baby diapers PCC and GCC are comparatively cheaper than wood fiber. Hence, it is used for manufacturing papers. Around 10 or 20 per cent of printing or writing paper contains calcium carbonate In the recent years, it is used as a replacement for kaolin in producing glossy papers This is most commonly used as an extender in paints , especially emulsion paints. Over 30 per cent of the weight of paint will comprise chalk or marble This is also used as filler in plastics Calcium carbonate is used in thermoplastic industry for manufacturing PVC The component is used for cleaning tarnish over silver PCC Manufacturers in India, Tamil Nadu One among the Precipitated Calcium Carbonate Manufacturers in South India is Aranthaangi Chemical Products Limited (ACPL). ACPL, the Manufacturer of Precipitated Calcium Carbonate was launched in the year 1983 as a very small unit in Pudukottai. It was earlier named Aranthaangi Chemicals Pvt Ltd. Here, they produce Calcium Carbonate in India that suits both Indian as well as international markets. Here, calcium carbonate is manufactured from imported limestone. The overall production of the company is 24000 MT per year. 5. With their well-groomed staff members, they are able to deliver quality products within stipulated time period. Few of the industries to which they supply the material are: paper, detergent, paint, rubber, food products, tooth paste, PVC pipe, cosmetics, ink, pharmaceutical, water proof chemicals, etc. Source: http://www.acpl.co/
