VSV GROUP is one of the leader suppliers for Calcium Carbonate for paper. A bright white Calcium Carbonate is added to the 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 mills 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 for 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 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 its high brightness and purity. Generally, the particle shape of Ground Calcium Carbonate is rhombohedral. This filler material is used in the alkaline wood-free papermaking process. The brightness of GCC is 86-95%.
