摘　　要： 对激光打印废纸的脱墨进行了研究。结果表明,激光打印废纸的碎解宜采用高浓、高转速及较高的温度并适当延长碎浆时间;常规脱墨化学品如氢氧化钠、硅酸钠及过氧化氢对脱墨的贡献较少,脱墨表面活性剂起主要作用。激光打印废纸更适合采用中性脱墨工艺。 The paper investigates the deinking of laser printing waste paper. The results show that for the smashing of laser printing waste paper the high concentration, high rotary speed deinking and high temperature are needed and the pulping time should be moderately extended, that deinking chemicals such as sodium hydroxide, sodium silicate, and peroxide had less contributions to the deinking of laser printing waste paper and that surfactants played an important role in the process of deinking. Neutral deinking process is more suitable to the laser printing waste paper.
