摘要:介绍了国外一些研究单位对中性脱墨和碱性脱墨结合应用所进行的研究，总结了中性脱墨与碱性脱墨相结合进行脱墨的优点。

Abstract:A two-stage deinking precess (first loop in neutral condition and second loop in alkaline condition) has been studied abroad. The results show that this process is efficient for deinking all paper grades, mixtures containing flexo, the data presented show that with this process the brightness obtained is higher than that with any other alkaline deinking process.
