THE EFFECT OF DIFFERENT STABILIZERS ON ALKALINE H2O2 BLEACHING OF NS REED PULP

This paper uses a new stabilizer of H2O2 bleaching and compares the stabilizing effect of the new stabilizer with that of Na2SiO3. The results show that the new stabilizer is better than the conventional Na2SiO3. The optimum conditions of the stable latterprocess bleaching of H2O2 as follow: NaOH 3%,MgSO4 0.05%, H2O2 3%, stabilizer 3%, temperature80℃, concentration 12%, time 3h.
