| Abstract: | This paper researches the bleaching effect of reductive bleaching agent FAS in oxidation and reduction process to mixed waste paper deinked pulp.Adding FAS and do reductive bleaching on the basis of H2O2 prebleaching,this paper discusses the effect of different bleaching temperature,different bleaching time and volume of FAS to the whiteness of pulp.The result shows that the bleaching effect and production cost appeared to be the best on the condition that the proportion of alkali is 0.4,volume FAS is 0.6%,pulp consistency is 8%,time is 40 min and temperature is 75℃ |
