摘　　要：研究烟草纤维的形态,并对烟草浆的湿部电荷特性进行研究。结果表明:烟草浆中纤维含量较少,短纤维的含量也不高,烟末和杂细胞含量较高。随着pH值的提高,烟草浆中溶胶物质的阳离子需求量随之增大,pH值由4.8升高到10.0时,阳离子需求量由0.07meq·L-1升高到0.28meq·L-1,增加了300%,但Zeta电位则由-5mV降低到-9.9mV,降低了70%;随着离子浓度、浆浓和打浆度的增加,烟草浆中溶胶物质的阳离子需求量和Zeta电位都随之增加。The formation of the tobacco stock and the tobacco pulp charge properties in the wet department were analyzed.The results showed that the contents of the fiber and the short fibers in the tobacco pulp are low, but tobacco waste and miscellaneous cells are high. With the increase of the pH value, the sol material cationic demand in the tobacco pulp increase, when pH increase from 4.8 to 10.0, the cationic demand increase by 300% from 0.007meq·L^-1 to 0.28meq·L^-1, but Zeta potential reduce by 70% from -5 mV to -9 mV; With the concentration of the ions, the concentration of the pulp and the beating degree increase, the sol material cationic demand in the tobacco pulp and Zeta potential increase.
