摘要

本省竹材加工業發達，以竹材加工廢料來生產紙漿，不但可解決廢料處理的問題，同時亦可提供部份製漿之原料，所用之試材為孟宗竹、麻竹及種竹之加工廢料。製成NSAQ竹漿后，可以次亞氯酸鈉單段漂白，其白度可違70% GE。若以高溫，鐘時間吹氣酸齣加過氧化氫二段漂白，可提高白度，增加白度穩定性，在NS-AQ竹漿可以此法標至75% GE。C-E-H-P四段漂白可將NS-AQ竹漿漂至72% GE。H_2O_2，於最後階段漂白，有增加白度穩定性之效果。

The bamboo handicraft industry in Taiwan is well developed, the use of bamboo waste as a raw material for pulp and paper making can not only solve the problem of waste disposal, but also partially solve the problem of raw material shortage; the bamboo, was t es used in this study belong to the following three species: Moso bamboo (Phyllstachys edulis Riviere), Makino bamboo ('Phyllstachys makino Hay) and Ma bamboo (Dendrocalamus latiflorus Munro). AS-AQ bamboo pulp can be beeached in a hypochlorite single stage to 70% GE brightness. the same pulp can be bleached in a HP sequence to 75% GE brightness, using. higher temperature and shorter reaction time NS-AQ bamboo pulp can also be bleached in a CEHP sequence to 72% GE brightness.
