Product Character
The product line developed by the company using the wet processing from ultrafine grinding. Output of 150,000 tons / year, the quality of long-term stability. Selection of high purity calcium carbonate mining and dispersing agent for major high-quality raw materials, products of high, uniform color; fine grain absorption, distribution reasonable, no big particles; grain shape Guangrun; wear value of low solids content accurately, viscosity stability , the high dispersion. Using this product can be a high percentage (use less or no kaolin) to facilitate the preparation of high solid content flow of good ﹑ slurry coating, drying saving energy consumption, significantly decreased the amount of adhesive, coating improve the whiteness of the paper is not transparent ﹑ ﹑ smoothness and gloss printing, a marked improvement in the quality of the printing paper, the paper is an ideal coating pigments.

A description of the use of
Quantitative coated with porcelain clay in a high shear mixer, mixed with scattered, solid content of 65 ~ 70%, and in large quantities by adding sodium polyacrylate dispersant. Although this product sieve over very low, but if mixed with other pigments, it was recommended by paint still head higher screen filter.
