WHAT IS CATIONIC STARCH?
CATIONIC which is a type of modified starch carries a formal positive charge over entire pH range, creating their affinity towards negatively charged substrates such as cellulose fibers and some synthetic fibers.
APPLICATION:
– It is widely used by paper manufacturers to increase the strength and retention.
Cationic starch apparently improves the retention of fillers. The fillers such titan dioxide, clay, talc and calcium carbonate are frequently incorporated with the furnish of a paper machine to improve the opacity of high grade of fine paper and light weight paper.
When filler retention rate increases, paper sheet tends to lose the strength and stiffness because the filler reduces the bond of fiber to fiber.
– Cationic charged starch can improve both the strength properties
and retention of fillers. Thus it also helps to reduce BOD and COD in the white water.
Besides that, cationic starch also improves the drainage at the forming section, sheet formation and efficiency of sizing chemicals in paper
BENEFITS OF CATIONIC STARCH IN PAPER MILL
Cationic starch enhances paper strength, water drainage, retention, improve paper quality; reduced dusting, linting and size addition; greater control of paper making process hence less paper web breaks and improve paper machine runnability as well as productivity. Cationic starch also allowed using more filler and more recycled fibers so reduce furnishes cost. As a surface size agent, cationic starch improves stiffness, opacity, printing quality and brightness.
