A method for minimizing pitch, ink, and stickies particle deposits in the paper making process by causing the retention of such particles onto fiber, comprising the steps of adding an effective pitch, ink, and stickies controlling amount of talc 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.
L?invention concerne une méthode servant à minimiser les dépôts de particules de poix, d'encre et de fragments collants dans un procédé de fabrication du papier. La méthode consiste retenir ces particules sur des fibres en ajoutant une quantité régulatrice déterminée et efficace de talc sur une suspension de fibres en contact avec la machine à papier et les pièces connexes, et en ajoutant aussi une quantité régulatrice efficace de bentonite à la suspension, ce qui a pour effet d'optimiser la rétention sur les fibres et de réduire les dépôts de particules sur la machine à papier et les pièces connexes.
