| 摘 要： | 采用粗皮桉为原料，研究其AS-AQ浆的ECF漂白性能。实验的主要结果如下：采用D-Ep-D漂白，总用氯量为2．4％时，家系125纸浆的白度达到84．O％IS0，黏度868ml／g，卡伯值8．34；家系200纸浆的白度达到84．6％ISO，黏度958ml／g，卡伯值8．15。提高第一段CIO2漂白的温度，家系123纸浆漂白后白度达到85．0％ISO，黏度855ml／g，卡伯值8．10；家系200纸浆白度达到86．2％ISO，黏度892ml／g，卡伯值7．98。采用O-D-Ep-D漂序，用氯量为1．2％时，家系125纸浆的白度为85．9％ISO。采用O-D—E—D漂白时，总用氟量仅为0．8％时家系200纸浆就可以达到78．0％ISO；当总用氯量达到2．4％时，纸浆的白度可以到84．1％ISO。
