Effect of Alkali Hydrogen Peroxide Pre-Extraction on APMP Pulping Process of Pink Sheets Bamboo

Abstract:

In this paper, the technique of alkali hydrogen peroxide extracting hemi-cellulose and the effects of pre-extraction on APMP pulping process of the Pink Sheets bamboo are investigated. The results show that the yields of pentosan and bamboo chip are optimal under the conditions of the dosage of hydrogen peroxide 1.5%, the reaction temperature 90°C, liquid ratio 1:8, holding time 4h. After pre-extracting the tensile index and folding strength decline, and the burst index is kept and the tear index increases slightly. But there is little loss to the brightness of APMP, and the refining energy is reduced largely after pre-extracted.
