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 effects of different bases on oxygen delignification of bamboo pulp were studied. The results showed that the effects of different bases on delignification were as follows: NaOH> Na2CO3> NH4OH> NaHCO3. The effect of different bases on the viscosity of oxygen delignification pulp was: NaOH> Na2CO3> NH4OH> NaHCO3. The effect of different alkali on whiteness of oxygen delignification pulp was: NaOH> Na2CO3> NaHCO3> NH4OH. The influence of different alkali on the SFCU was: NaOH> Na2CO3> NH4OH> NaHCO3.
