【Abstract】 The beating characteristics of broussonetia papyrifera vent pulp are studied in this paper. It has been observed that broussonetia papyrifera vent pulp is different from general pulp in beating characteristics and paper properties, namely, the beating of Broussonetia papyrifera vent pulp undergoes a period of difficult beating. The paper explains this difference from the angle of the changes in fibre morphology.更多还原
