Quality Evaluation Of Pulp
- Aug 23, 2018 -

The quality of the pulp mainly depends on the fiber shape and the purity of the fiber.

The nature of these two aspects is mainly determined by the type of raw materials used and the manufacturing methods and processing depth. In the fiber morphology, the average length of the fiber, the ratio of the thickness of the cell wall to the diameter of the cell and the content of the fibrous fibers and the fiber bundles in the pulp are the main factors. General fiber average length is big, the ratio of cell wall thickness to cell diameter is small, there is no or very few fibrous complex cells and fiber bundle of pulp has good bonding strength, dehydration and copying performance, can produce strong paper, belong to higher grade pulp, such as spruce coniferous wood pulp, cotton, hemp pulp and so on.
