Printing & Writing Paper
Technology, Application & Services for Printing & Writing Paper
Some printing & writing paper production is filled with calcium carbonate, resulting in low paper breakage. And due to the large price difference between CTMP and Kraft pulp, many paper mills hope to increase the amount of CTMP/APMP pulp to reduce raw material costs. However, the existing low-consistency refining of hardwood pulp or other short fibers has limited improvement in short fiber strength, making the paper strength performance not high enough. We use high-consistency refining to treat hardwood or other short-fibers pulp to improve strength, reduce the long-fiber pulp or kraft pulp ratio.

Processing Technology:
▌The advantages of applying high-consistency refining to Printing & Writing Paper:
▌Can effectively improve paper tensile strength, tear strength, folding endurance and other strength properties, and reduce long fibers usage;
▌High fiber retention rate, low concentration of white water under the mesh, good water filterability, effectively reducing production costs;
▌Improve the bonding performance of fine fibers and long fibers, reduce the phenomenon of powder dust, and increase ash content;
▌It can soften fibers, increase bulk, and improve the printability of paper;
▌Under the same strength index, the beating degree can be reduced and power consumption can be saved;
