摘要
弱碱性浮选脱墨是很多纸厂感兴趣的技术,本文介绍了弱碱性浮选脱墨的优点,与强碱性浮选脱墨相比,弱碱性浮选脱墨节省了氢氧化钠和过氧化氢的用量,降低了不同表面活性剂的用量,用相同的漂白方法,2种方法可以漂至很相近的白度。
Weak alkaline deinking is of interest to many mills, it has some advantages. Eompared with strong alkaline deinking, the deinked pulp from weak alkali deinking can be bleached to the same brightness with the same bleaching processes while the usage of NaOH, H2O2 and various surfactants are reduced.
