“Improved machine cleanliness enables an increase in machine speed even on lightweight grades, helps significantly reduce product defects, and extends e.g. in high-grammage paperboard grades, and also help improve the efficiency of other functional chemicals, such as sizing, in the papermaking process. In addition to being an excellent fixative for stickies control, they work well as retention and drainage boosters, improving dewatering performance e.g. The quick inversion polymers are multipurpose products. These products are the result of significant research into the right molecular weight and charge to find the optimal fixation performance to control the stickies,” says Michael Wallace, Senior Manager, Wet End Applications at Kemira. “Our customers need solutions that are cost-efficient, easy to apply, and compliant with modern regulations, e.g.
The new quick inversion polymers provide superior hydrophobic particle fixation and have proven success in improving machine cleanliness and with it, machine runnability and efficiency in both recycled linerboard and tissue grades. A common problem are the contaminants that are present in secondary fiber furnishes and can significantly reduce production efficiency and product quality. The increasing use of recycled fibers in paper and board production brings unique challenges for the manufacturers.
27, 2021 (Press Release) -Kemira’s new quick inversion polymer technology helps address one of the key concerns of recycled paper and board producers: stickies originating from tapes, glues, and labels used in recovered and recycled packaging material.
