Abstract:In this paper, deinking of MOW with cellulase treatment in cooperation with ultrasonic wave were studied. Results indicated the conditions including temperature 50℃, the amount of cellulase 1.5IU/g, pulping consistency 5 %, the time of enzymes act on pulp 60minutes, the amount of surfactant 0.05 %, pH5.5, the time of flotation 15minutes-20minutes, the pulping consistency of flotation 1% were optimized for cellulase deinking. And it also including frequency 20 kHz, temperature 40℃, pulping consistency 4% ,the time of treatment 4~5 minutes. Furthermore, the deinking pulps have higher whiteness and higher strength, the whiteness is more 4%ISO than the blank sample.
Keywords:waste paper  cellulose  ultrasonic wave  deinking
