摘要 研究了不同碱对竹浆氧脱木素的影响,结果表明,不同碱对脱木素的影响为:NaOH>Na2CO3>NH4OH>NaHCO3;不同碱对氧脱木素纸浆粘度的影响为:NaOH>Na2CO3>NH4OH>NaHCO3;不同碱对氧脱木素纸浆白度的影响为:NaOH>Na2CO3>NaHCO3>NH4OH;不同碱对纤维素单元剪切系数(SFCU)的影响为:NaOH>Na2CO3>NH4OH>NaHCO3。 The effect of different alkali on bamboo pulp oxygen delignification was studied, the results showed that the effect of different alkali on delignification: NaOH〉Na2CO3〉NHaOH〉 NaHCO3; the effect of different alkali on oxygen delignified pulp viscosity: NaOH〉Na2CO3 〉 NH4OH〉NaHCO3; the effect of different alkali on oxygen delignified pulp brightness: NaOH〉 Na2CO3〉NaHCO3 〉NH4OH; the effect of different alkali on SFCU(scission fraction of cellulose unit): NaOH 〉 Na2CO3 〉 NH4OH 〉 NaHCO3.
