| Nano-calcium carbonate for ink has the characteristics of ultra-fine and ultra-pure. The crystal shape and particle size are effectively controlled during the production process. The surface of the product is surface-modified by resin acid and special dispersant, and has good compatibility with ink resin. Therefore, it has the advantages of small particle size, narrow particle size distribution, good transparency, high gloss, and moderate fluidity in ink products, has a spatial three-dimensional structure, and has good dispersion characteristics. |
| Using activated nano calcium carbonate as a filler, the prepared ink has good printing performance and high stability. Nano calcium carbonate is easy to disperse in the ink and has good abrasion resistance, can adjust the ink color concentration, consistency and other physical properties, so that the ink has good printability, leveling, adhesion and excellent hiding power, and Can improve the gloss and brightness of the ink. |
