Calcium Carbonate for Paper and Printing

Product Description

Calcium Carbonate for Paper & Printing

Shivish Microns LLP is one of the leader suppliers for Calcium Carbonate for paper. A bright white Calcium Carbonate added to paper pulp as a filler in alkaline papers or applied as a coating pigment. It is used in alkaline papermaking, which is receiving increased interest due to the longer longevity of alkaline papers. Calcium Carbonate is the most abundant mineral on earth that is not silicon-based. Calcium Carbonate is also used as a white pigment in many printing inks. It can be coated to impart greater gloss to the ink surface. It is low in cost, and is commonly used as an extender in place of the more expensive Titanium Dioxide. Calcium Carbonate is used in paper mill as a filler material in the alkaline papermaking process. Nowadays Calcium Carbonate is dominant over other papermaking filler materials. The main reason behind the preference of Calcium Carbonate is the demand for brighter and bulkier paper. There are significant benefits to the use of Calcium Carbonate in the alkaline papermaking process. Usually Calcium Carbonate occurs in three natural forms such as Limestone, Chalk and Marble. Naturally it is formed between the reactions of Calcium salt and Carbon dioxide. This process is still going on in the oceans. There are two types of Calcium Carbonate used in paper mill Ground Calcium Carbonate (GCC) and Precipitated Calcium Carbonate (PCC). Ground Calcium Carbonate is manufactured by grinding Limestone or Marble because of their high brightness and purity. Generally the particle shape of Ground Calcium Carbonate is rhombohedral. This filler material is used in alkaline wood free papermaking process. The brightness of GCC is 86-95%. Shivish Microns LLP uses the most advanced techniques and methods to support the development of the most cost-effective, highest-performance coating formulations to meet the customer//s manufacturing and quality requirements. With Shivish Microns LLP R&D team, the top quality Calcium Carbonate products have been developed to serve wide range of paper manufacturing in a very efficient manner.
