| Abstract:The factors affecting the retention, drainage and handsheet physical properties of de-inked pulp by using cationic cassava residue, such as cationic cassava residue dosage, pH value, conductivity, and shearing force were studied. The results showed that when the dosage of cationic cassava residue was 0.5%~1.5%, the highest levels of the drainability and retention of de-inked pulp were 288 g/60 s and 87.7%, respectively. And cationic cassava residue improved paper strength obviously, the tensile index, bursting index, were increased by 25.9%, 11.9%, respectively. |
