通过光学显微镜对两种PET浆粕的形态进行了观察,采用纤维筛分仪对两种PET浆粕进行尺寸分级,通过比表面积分析仪对两种浆粕的比表面积进行了测试,并将两种浆粕与PET短纤制备复合纸,对两种浆粕的成纸性能进行了比较。 The morphology of the two kinds of PET pulp was observed by optical microscope. The size of the two kinds of PET pulp was graded by fiber sieve analyzer. The specific surface area of ​​the two kinds of pulp was tested by the specific surface area analyzer. Pulp and PET staple fibers were prepared from composite paper, paper pulp properties of the two were compared.
