The effect of anionic charge reduction of deinked pulp in Physical Strengths Improvement

Wet tensile strength is very important in some cellulosic health products. When these products produced during the recycling process some of the characteristics in pulp suspension due to lack of stability of desirable quality properties is difficult to achieve. In this study, using a variety of diff...
