Calcium Carbonate for Papermaking

Calcium carbonate is widely used in Papermaking industry, it is used as filler. Kefid calcium carbonate crusher and calcium carbonate grinding mill can processing the calcium carbonate to the suitable size or fineness, then the calcium carbonate can be used as the filler in Papermaking. Here we recommend you the calcium carbonate High Pressure Mill and the calcium carbonate Vertical Mill, if need the price, please chat online.

Calcium carbonate in papermaking mainly for filler paper, in order to ensure a certain strength of paper, whiteness, while reducing costs, adding a lot of calcium carbonate in the paper. Paper industry is based on extensive use of calcium carbonate from the international paper industry turning acidic alkaline or neutral papermaking process causing paper craft, so you can use a large number of inexpensive calcium carbonate talc and clay instead of the past. Light calcium carbonate as a filler for paper, has several advantages over kaolin and FGCC.
1, with a high opacity and gloss.
2, as a filler, an increase of high capacity.
3, uniform particle size.
4, the color remains strong.

The paper can be improved by adding calcium carbonate opacity and brightness of paper, improving smoothness and uniformity of the state of paper, to increase the softness of the paper, reducing the moisture absorption and deformation of the paper, to improve the printing of the ink absorption performance, increase retention.

Specialty products for coating paper with a color white, high gloss, transparency, small, large refractive index, scattering coefficient, opacity characteristics, especially for recording paper thin pages printing paper, coated paper high whiteness the manufacture of paper and other high.
