A Determining Method of Paper Fiber Density and Equivalent Diameter

Abstract:

It is very important to measure paper fiber density and equivalent diameter for pulp suspension as solid-liquid two-phase flow in fluid dynamics study. There are some kinds of ways to measure fiber density，but not be suit for pulp fiber density because of their limitations. By using kajaaniFS300 fiber analyzer provided by Mesto ltd company to compare and measure all kinds of fiber length, fiber coarseness, weight average fiber length can more accurately show the actual length of fiber. The results shows that it is apparently more appropriate to calculate fiber density by using fiber coarseness, weight-average fiber length and weight-average fiber width, and fiber equivalent diameter should also be calculated according to the same weight-average fiber length and weight-average fiber width.
