柞木浆强度特性的比较

The Comparison of Strength Property for Quercus Pulps

对柞木的硫酸盐浆 (KP)、碱性亚硫酸盐 -蒽醌浆 (AS -AQ)及中性亚硫酸盐 -蒽醌浆 (NS -AQ)的强度特性进行了比较。结果表明 ,AS -AQ的抗张、耐破、撕裂及耐折强度均高于KP及NS -AQ ,而NS -AQ的抗张及耐破强度与KP相当 ,耐折强度优于KP 。

The comparison of strength property between kraft pulp (KP) and alkaline sulfite-anthrapuinone pulp (AS-AQ) and neutral sulfite-anthraquinone pulp (NS-AQ) for Quercus was studied. The results showed that the tensile, burst, tear and folding strength of AS-AQ all higher than one of KP and NS-AQ. The tensile and burst strength of NS-AQ correspond to one of KP. The folding strength of NS-AQ higher,and tear lower than one of KP.
