对两种不同卡伯值的Soda AQ麦草浆 ,分别采用不同的TCF漂序进行漂白。实验结果表明 ,在总H2 O2 用量 5 %下对较低卡伯值未漂浆采用EAPPht、APPhtY漂序 ,对较高卡伯值未漂浆采用AP (PO)、 (AP Q)PO、 (XQ)Pht等漂序 ,均取得了 80 %SBD以上的白度和较好的粘度。
Two different Kappa values of Soda AQ wheat straw pulp were bleached using different TCF bleaching. The experimental results showed that the EAPPht and APPhtY bleaching were carried out on the lower kappa number of unbleached pulp at 5% total H 2 O 2, and AP (PO), (AP Q) PO and XQ) Pht and other bleaching, have achieved more than 80% SBD whiteness and better viscosity.
