氧脱木素技术研究及应用进展

Procession of Researching and Application in Oxygen Delignification

氧脱木素作为一种先进的、环保型的制浆漂白技术,在我国正逐渐受到造纸工作者的重视,并逐渐得到越来越广泛的应用。根据我国的实际情况,研究和推广草浆的氧脱木素,并进一步研究提高草浆氧脱木素程度和脱木素选择性的方法,对解决我国造纸工业废水污染严重,实现纸浆的少氯和无氯漂白具有重要的意义。

Oxygen delignification is a phase input between cocking and washing, removing lignin with oxygen in alkali, as the successor of delignification in cocking. As an advanced environmental bleaching technology, oxygen deligninfication has been being fixed on. According to the situation in our country, researching and developing of oxygen deligninfication is of great advantage of resolving serious pollution of liquid and practising with chlorine release or free in bleaching, with further research of deligninfication in wheat and selective deligninfication.
