杨木P-RC APMP工艺中MgO部分替代NaOH对溶解与胶体物质的影响
Effects of Partial Substitution of MgO for NaOH on Dissolved and Colloidal Substances in Poplar P-RC APMP
摘要
Abstract
In this study,different percentages of MgO were used to substitute for NaOH at the high-consistency retention stage of poplar P-RC APMP,and the effects of the substitution of MgO for NaOH on dissolved and colloidal substances (DCS)were studied.The results showed that the pH,mass concentration,conductivity and cationic demand(CD)of the DCS and dissolved substances(DS)were reduced with the increase of substitution percentage of MgO for NaOH.The conductivity and CD of DCS are mainly attributed to DS.The bulk and light-scattering coefficient of the P-RC APMP handsheet were in-creased while its strength properties were decreased with the increase of substitution percentage of MgO for NaOH.关键词
