Problems solved by technology

[0002] Due to the relatively low basis weight of ultra-low basis weight household paper, when it is wrinkled, the strength of the paper will lose a lot, and it is easy to cause paper breakage
The paper is generally broken from both sides, which leads to the break of the whole paper web, and a lot of pulp and energy consumption will be wasted during threading, which will reduce the operating efficiency of the paper machine

Abstract

The invention discloses paper making technology of ultra lightweight tissue paper.The paper making technology of ultra lightweight tissue paper comprises following steps: pulp scattering, de-slagging, pulp refining, dilution, screening, netting and forming, squeeze dehydration, drying, wrinkling and primary rolling. A drying cylinder coating is adopted for softening, adjusting and wrinkling the scraper angle. During the paper making process, the frequency of shutdown due to paper-breaking is decreased by adding measures such as increase in paper weight in a transverse direction of a paper machine so that operation efficiency of the paper machine is increased.

Description

technical field [0001] The invention relates to the technical field of papermaking technology for household paper, in particular to a papermaking technology for ultra-low weight tissue paper. Background technique [0002] Due to the relatively low basis weight of ultra-low basis weight household paper, when it is wrinkled, the strength of the paper will lose a lot, and it is easy to cause paper breakage. The paper is generally broken from both sides, resulting in the break of the entire paper web, a lot of pulp and energy consumption will be wasted during threading, and the operating efficiency of the paper machine will be reduced. Contents of the invention [0003] The object of the present invention is to provide a kind of ultra-low weight tissue papermaking process for the above-mentioned defects, including loose pulp, slag removal, pulp refining, pulp blending, dilution, screening, online forming, dehydration pressing, drying, Wrinkling, initial roll, using measures s...
