Abstract

Abstract: Properties of alkaline peroxide mechanical pulp (APMP) and sulfonated chemi-mechanical pulp (SCMP) from reed were investigated, and the main chemical constituents of reed were determined. The results showed that reed used in this study has the characteristics of high cellulose content, and low contents of 1%NaOH extractives and pentosan. Optimum pretreatment conditions of APMP and SCMP of reed were selected through orthogonal or conditional experiments. APMP experimental results showed that properties of reed APMP such as brightness 57.8%(ISO), breaking length 2.82 km and tear index 3.7 mN·m²/g can be obtained after two-stage alkaline peroxide pretreatment. SCMP experimental results showed that brightness, breaking length and tear index of unbleached reed SCMP are 40.6%(ISO), 3.48 km and 4.2 mN·m²/g, respectively. High brightness of 51.3%(ISO)could be obtained when the pulp was further bleached with 2% H₂O₂ under the optimum condition of single stage peroxide bleaching.
