发明名称 PRODUCTION OF PAPER
摘要 Production of Paper Internally sized paper is made by incorporating cationic retention aid into a cellulosic suspension to form flocs, breaking these down to microflocs, aggregating them by bentonite or other anionic polymeric material, draining the suspension and drying the resultant sheet, and the size is incorporated in the suspension as a non-ionic or anionic emulsion after the addition of the cationic retention aid.
