Paper and Printing Industry
The paper and printing industry has high demands on paper whiteness, opacity, surface smoothness, and printability. The company’s industrially precipitated calcium carbonate and heavy calcium carbonate can effectively enhance paper quality and optimize production processes.
(1) Industrial Precipitated Calcium Carbonate (PCC)
Industrial precipitated calcium carbonate is a key functional additive in the paper-making industry, offering excellent optical and filling properties. During the paper-making process, it can replace some of the more expensive plant fibers, thereby reducing raw material costs while significantly enhancing the whiteness and opacity of the paper—resulting in sharper printed images and more vibrant colors. Its uniform particle size and well-defined particle shape effectively fill the gaps between paper fibers, improving surface smoothness and making high-speed printing smoother and more efficient, while also cutting down on ink consumption during the process. Moreover, industrial precipitated calcium carbonate enhances the drainage performance of the pulp, shortening drying time and boosting overall paper production efficiency. It also exhibits excellent compatibility with sizing agents, further strengthening the paper's water resistance and expanding its range of applications.
(II) Heavy Calcium Carbonate
Heavy calcium carbonate is primarily used in the paper industry for producing coated paper, cultural paper, and other products. It exhibits excellent dispersibility, allowing it to distribute evenly throughout the paper coating, thereby enhancing the coating's smoothness and abrasion resistance. This, in turn, makes the paper surface more receptive to ink adhesion, significantly improving print quality. At the same time, heavy calcium carbonate is cost-effective, helping to reduce overall paper production costs. Moreover, during the manufacturing process, it does not negatively impact the strength or flexibility of the paper, striking a perfect balance between performance and affordability to meet the production needs of paper-making enterprises.
