摘要:

利用碱法造纸废液合成磺甲基化碱木素,将它与FeSO4•2H2O复配成泥浆稀释剂,通过泥浆性能测试,结果表明具有良好的抗温能力和稀释效果,并具有一定的降失水能力,同时还排除了铬对环境的污染。

关键词: 碱木素, 磺酸盐, 磺化, 泥浆, 稀释剂

Abstract:

Lignosulfonate can be synthesized with the scrap produced in alkali papermaking process and it can further be mixed wity 4 % FeSO4•2H2O into a slurry deluent. The determination of the slurryoperties shows that it has the characteristics of good temperatureresistance and dilution effect, and certain water-loss capacity as well. At the same time it eliminates the pollution of chromium to environment.

Key words: Alkaly lignin, Sulfonats, Sulfonation, Slurry diluent
