摘　　要：进行了90 t/d用化学法除去松香中的铝及其他金属元素的工艺试验。探索了不同水质和间歇法与连续法对松香除铝程度的影响。实验表明,在保证松香的其他优良品质前提下使松香中铝和灰分含量大幅降低。Process of 90t/d on the removal of aluminum and lower of ash from Yunnan gum rosin was studied, and effect of different water quality and intermittent method on the removal of aluminum was investigated. Result showed that large content of aluminum and ash was lowered on the premise of quality assurance of gum rosin.
