发明名称 Förfarande vid framställning av cellulosamassa och användning av förening vid förfarandet
摘要 Cellulose pulp, which has a low tendency to give rise to static electricity when subjected to dry defibration and has retained its good wettability, is produced by adding an ammonium compound, which contains one quaternary nitrogen and one or two substituents, which contains a higher hydrocarbon group having 6-15 carbon atoms, and has an HLB value of 9-14 according to Davies, the quaternary nitrogen having been assigned the value +9.4, to wet or dry cellulose pulp in an amount of 0.1-5 kg/tonne of absolutely dry cellulose pulp.
