Adsorption - high oil absorption value, improves the printing properties of paper ink, reduces resin interference in the papermaking process, and improves the cleanliness of white water. It is also a good waste paper deinking agent, which is beneficial to improve the retention rate of organic additives in the wet part of the paper machine;
Lubricity - improves paper adhesion and production operability (cleanliness of scrapers, drying cylinders, and finishing equipment); gives paper excellent hand feel, softness, and finishing; reduces the amount of coating lubricants used;
Chemical stability - suitable for various papermaking sizing systems, compared with fillers such as calcium carbonate and kaolin, it can save the amount of chemical additives added and give paper a good sizing effect. It is excellently compatible with various pigments, latex, and auxiliary additives in the coating system. Soft and low hardness: low abrasion; high crushing ratio, relatively easy powder processing, can reduce the wear of processing equipment and papermaking and printing equipment, and improve the finishing effect of paper;
Hydrophobicity - improve paper water resistance and reduce paper hygroscopicity. Flake structure: gives coated paper excellent smoothness, gloss, roughness, concealment, and printability, and is an ideal mineral that can replace water-selected kaolin for papermaking coatings.
