In this paper, we studied the cycle reuse times of poplar APMP pulp and the effect of beating on opacity and intensity. It is found that the opacity of APMP pulp increases with the increase of fiber reuse times, while the tensile strength increases slightly.With the increase of beating degree,the opacity gradually decreases, and the tensile strength increases first and then decreases.%研究了杨木APMP浆的循环回用次数及打浆对不透明度和强度的影响.通过研究发现,APMP浆随着纤维回用次数的增加,不透明度逐渐增大,而抗张强度略有增加.随着打浆度的增加,不透明度逐渐下降,抗张强度先增后减.
