Cationic Starch in Paper Making
On the application of cationic starch in papermaking
The art of papermaking has a long history. Since Cai Lun improved it, it has benefited thousands of years. Today's papermaking process is becoming more and more delicate, and many materials and techniques are integrated into it. The application of cationic starch in papermaking is particularly critical.
For cationic starch, its molecular structure contains cationic groups. This unique structure gives it a special ability to interact with papermaking raw materials. In the papermaking process, the bonding force between fibers is related to the performance of paper. Cationic starch attracts each other with cationic groups and negatively charged fibers, acting as a bond, tightly connecting the fibers and enhancing the physical strength of paper, such as tensile strength and burst resistance.
In the papermaking process, cationic starch can be used as a retention aid and filter aid. In the pulp suspension, fine particles and fibers are easily lost, which affects the quality and production efficiency of paper. Cationic starch can adsorb on the surface of fibers and fillers, promote their flocculation, enable particles to remain on the paper, reduce loss, accelerate dehydration rate, improve water filtration, and make the papermaking process smoother and more efficient.
Furthermore, in the process of paper sizing, cationic starch also has outstanding performance. It can work synergistically with sizing agents to enhance the combination of sizing agents and fibers, and improve the water resistance of paper. Paper treated with cationic starch is not easy to be inked and deformed in contact with water, and is suitable for printing, writing and other purposes.
If you want to make good use of cationic starch in papermaking, you need to study the process conditions in detail. The degree of cationization of starch, the amount of addition, the timing of addition, and the pH value of the system all have a profound impact on its function. Only by precisely regulating various factors can cationic starch be fully effective in papermaking and produce excellent quality paper.
The papermaking industry has added new colors due to the application of cationic starch. In the future, with the deepening of research and the advancement of technology, cationic starch will be able to bloom more brilliantly in the field of papermaking, promoting the papermaking process to a new height.
