发明名称 Combination of poly (dadmac/acrylamide) and bentonite for deposition control in papermaking processes
摘要 <p>A method for minimizing pitch, ink, and stickies particle deposits in the papermaking process by causing the retention of such particles onto fiber, comprising the steps of adding an effective pitch, ink, and stickies controlling amount of a water soluble diallyldimethyl ammonium chloride-acrylamide copolymer to a suspension of fiber in contact with the paper machine and associated parts and adding an effective pitch, ink, and stickies controlling amount of bentonite to the suspension, thereby increasing retention of pitch, ink, and stickies onto the fiber and minimizing the deposition of pitch, ink, and stickies particles on the paper machine and associated parts.</p>
