摘要
对碱法麦草浆进行了HD漂白研究。研究表明 :碱法麦草浆采用HD短序漂白工艺优于CEH三段漂白工艺。麦草浆经HD漂白后 ,白度可以达到 78%ISO ,得率有所提高 ,物理性能明显改善 ,环境污染负荷降低 ,可以取代传统的CEH三段漂白。
Bleaching of wheat straw alkali pulp with HD short sequence was studied in this paper. The study results indicated that HD bleaching was superior to CEH bleaching for wheat straw alkali pulp. The brightness of the bleached pull could be reached to 78%ISO, the bleached pulp yield increased, the physical property of the pulp was improved evidently and the pollution load reduced significantly when the pulp was bleached with HD sequence. HD sequence could be used as the substitute for the conventional CEH process.
