The functional nano-active calcium carbonate produced by the company not only meets the demand for high-end fillers in the papermaking industry after technological transformation. As a paper-making filler, nano-active calcium carbonate has the following advantages: high light shielding and high brightness, which can improve the whiteness and light shielding of paper products. The high expansion property enables paper mills to use more fillers and significantly reduce raw material costs. The particle size is fine and uniform, making the products more uniform and smooth. The oil absorption value is high, and it can improve the color fastness of colored paper. The filling amount is.
Using active nano-calcium carbonate as filler, the prepared ink has good body and viscosity, good printing performance, and high stability. Since nano-calcium carbonate and ink resin are easily miscible and mixed, the printed product is smooth, with complete dots, strong hiding power, and glossiness comparable to products filled with aluminum barium white. Nano-calcium carbonate is used as a filler to improve the gloss and brightness of the ink. It can also show good ink absorption during the ink printing process, which helps to improve the quick-drying performance of the ink.
The surface of this series of products is treated with resin acid and special dispersant. It has good compatibility with ink resin, excellent dispersion, transparency, excellent gloss covering power and good fluidity, permeability and dryness. It is suitable for With high-speed printing, performance indicators such as ink color viscosity and consistency can be adjusted as needed to reduce ink costs. Different products in the series are respectively suitable for the production needs of various high, medium and low-end inks.
