Abstract:The bamboo alkaline peroxide mechanical pulp (APMP) production is plagued by difficulty in chemical liquid penetration, high energy consumption, and poor pulp properties. The effects of the polyethylene glycol fatty acid ester penetrating agent (P1) and the fatty alcohol polyether penetrating agent (P2) on the pulp performance and energy consumption of Bambusa Rigida APMP were systematically studied. The results showed that the applications of both P1 and P2 could reduce energy consumption and improve pulp properties, effectively. The energy consumptions of Bambusa Rigida APMP (Canadian standard freeness (CSF) values of pulps were controlled in the range of 300 to 350 mL) with P1 and P2 addition (dosage of 0.05%, oven dry), were reduced by 13.5% and 9.0% by comparison with the control group, respectively. The fiber bundle contents of pulp were decreased by 52.9% and 23.5%, while the fiber fibrillation ratios of pulp were increased by 17.3% and 7.2% by adding P1 and P2, respectively. Similarly, the tensile index, tear index, and burst index of the handsheets were increased by 30.5%, 16.4%, and 46.4% with P1 addition, while those indexes were increased by 12.7%, 21.5% and 10.7% with P2 addition.
