Technical Field

The utility model belongs to the technical field of papermaking, specifically indicate a papermaking uses abrasive disc.

Background

Papermaking is an important invention for ancient Chinese workers; the method comprises two modes of mechanism and manual operation, wherein the mechanism is continuously carried out on a paper machine, pulp suitable for paper quality is diluted to certain concentration by water, and is preliminarily dehydrated in a wire part of the paper machine to form wet paper sheets, and the wet paper sheets are pressed, dehydrated and dried to form paper. Manually, the fibers dispersed and suspended in water are made into wet paper sheets by a frame with a bamboo curtain, a polyester net or a copper net, and the wet paper sheets are pressed, dehydrated and dried in the sun or dried to form paper; the paper manufactured by the machine and the manual is the biggest difference that the fibers in the paper pulp are well preserved because the manual beating is adopted by the manual paper; the mechanical paper is beaten by a machine, and the paper pulp fibers are broken. So that the toughness and tension of the hand-made paper are greatly superior to those of the machine-made paper. In the process of papermaking, a pulping machine is needed for pulping, namely, the fibers in paper pulp are treated by using a grinding disc tooth pattern mechanical action method to be fluffed, properly cut and devillicate, more importantly, the fibers absorb water and swell during pulping, so that the fibers have high elasticity and plasticity, the production requirement of a paper machine is met, the paper pulp is easily accumulated on the top of the conventional grinding disc, so that part of the fibers in the paper pulp are deposited on the grinding disc, the fibers in the paper pulp are reduced, and the quality of the pulp after pulping is influenced.
