Title: Surfactant and Hydrogen Peroxide Reinforced Oxygen Delignification
Abstract: In order to improve the efficiency of oxygen delignification, the effect of surfactant OB and hydrogent peroxide on bamboo pulp oxygen delignification were investigated, when OB and hydrogent peroxide were added into bamboo pulp separately and in combination. The results showed that:the effect of oxygen delignification can be improved by surfactant OB, further more when OB dosage 0.3%, H2O2 charge 0.5%, the delignification rate of bamboo pulp can improve 19.4 points of percentage, and the brightness can improve 10.2%ISO, however, the viscosity loss was small. What’s more the bamboo pulp’s brightness can reach 82.1%ISO after OQP bleaching.
