| Abstract:In this paper, cotton pulp as the research object, the best washing paramenters were determoned by orthogonal test. The effects of residual chlorine, Ca2+, and Na+ concentration on the viscosity in high quality water, were discussed during washing process. ClO2 bleaching liquid was made through R5. And the effect of its concentration on the viscosity was studied during bleaching process. The results showed that the order of four factors influenced the viscosity in different degrees: residual chlorine> Ca2+>residence time>pH. When the residual chlorine concentration was 0.036 g/L, the Ca2+concentration 90 mg/L, the residence time 1 h and the pH 7, the high quality water of washing could be achieved. When residual chlorine concentration in high quality water was changed, viscosity decent rate had intended to increase after decreasing with the increase of residual chlorine, and the minimum rate was 11%. When Ca2+ concentration was altered, it was discovered that the minimum rate could be realized with Ca2+ concentration being 110 mg/L. When NaCl was added to the high quality water, the rate could be 2.2%. When bleaching liquid purity was changed in bleaching process, the rate could only be 2.1%. |
