摘要： 以尾巨桉和马占相思为原料,采用经化学预处理的碱性过氧化氢机械浆(P-RC APMP)制浆工艺对比研究两者的制浆性能.研究结果表明,相同的 H2O2用量(4.0%)和NaOH用量(3.5%)条件下,2种原料制得纸浆的白度相近,均可达75%左右;马占相思原料制浆得率比尾巨桉约高3%左右,物理强度性能远优于尾巨桉浆,相同的250mL加拿大标准游离度(CSF)下,尾巨桉纸页的抗张强度仅为20.1N·m/g,而马占相思纸页的抗张强度可达到2.0N·m/g以上.制得相近CSF的纸浆,马占相思制浆所需的磨浆电耗比尾巨桉略高;2种原料制浆废水的化学耗氧量(COD)和生物耗氧量(BOD)发生量相近,而尾巨桉的制浆废水中固体悬浮物(SS)及总固形物(TS)含量远高于马占相思废水.

Abstract: Pulping properties of Eucalyptus urograndis×E.grandis (E.u.×E.g.) and Acacia mangium Willd. wood chips were investigated by using preconditioning refinerchemical alkaline peroxide mechanical pulping(P-RC APMP) process. Specific refining energies were recorded and both physical properties and optical properties of pulps were evaluated. Results show that similar brightness of P-RC APMP pulps could be produced from both E.u.×E.g. and A.mangium wood chips. At the chemical dosage level of H2O2 4.0% and NaOH 3.5%, which is a very low chemical consumption, pulp brightness of both pulps was able to reach 75%ISO. The pulp yield of A. mangium wood chips was 3.0% higher than that of E.u.×E.g. wood chip. At the freeness level of 250mL Canadian Standard Freeness (CSF), pulps from A.mangium wood chips was much stronger than that from E.u.×E.g.. For example, the tensile strength of P-RC APMP pulp from A.mangium was above 26N·m/g, about 30% higher than that of E.u.×E.g. pulp; Further refining could improve chemimechanical pulp strength. For the same CSF level,pulping of A.mangium wood chips requires more refining energy than that of E.u.×E.g. wood chips.
