参照日本脱墨剂专利探讨废纸脱墨问题

本文在分析保定地区废纸脱墨造纸现状及存在问题后，总结了废纸脱墨试验及脱墨剂的研制。选用脂肪酸系脱墨剂，以洗涤法进行脱墨，脱墨效果良好，研制出以含有“天然油脂和多元醇的混合物与环氧化物的加成物”为特征的HX－2型脱墨剂，经生产应用，再生纸的白度、残留油墨数等项指标均达到造纸要求。

Investigation on Deinking Process with Reference to theJapanese

This paper discussed the manufacture of deinking agents with reference to the japanese patents. A HX -2 type deinking agent containing the adduct of epoxide and a mixture of natural fat and polyhydric alcohol was developed with reference to the Japanese patent JP60 - 239585. Both the whiteness of the deinked paper and the number of the residue ink can meet the requirement by using this deinking agent.
