Problems solved by technology

In the current coating rate detection process, the determination of the dry weight of the film base and the dry weight of the finished product needs to take a large piece of paper web at the material outlet of the paper machine and the material outlet of the drying process for sample preparation. During the sampling process, continuous paper webs will be formed. breakage, which interrupts the continuous production of the paper web and also poses hidden dangers to safety production
Compared with the film-based quantitative sample preparation sample and the finished product absolute dry quantitative sample preparation sample, because the two samples have been dried before and after, the shrinkage of the paper has an impact on the sample area, resulting in the two samples being quantitatively inaccurate. cloth rate can not accurately express the real value

Abstract

The invention relates to a measuring method for a spreading rate in a paper-making reconstituted tobacco production process, belonging to the technical field of paper-making reconstituted tobacco production. The measuring method for the spraying rate in the paper-making reconstituted tobacco production process comprises the following steps: (1) measuring chlorine content c1 of approached stock in the production process by adopting a flow chemical analyzer; (2) measuring the chlorine content c2 in coating liquor in the production process by adopting the flow chemical analyzer; (3) measuring the chlorine content c3 of a reconstituted tobacco finished product by adopting the flow chemical analyzer; (4) calculating the spreading rate x of paper-making reconstituted tobacco according to the following formula: x=(c3-c1) / (c2-c1)*100%. The measuring method for the spreading rate in the paper-making reconstituted tobacco is higher in degree of accuracy and capable of objectively representing the spreading rate of the paper-making reconstituted tobacco.

Description

technical field [0001] The invention relates to a coating rate detection method in the production process of reconstituted tobacco leaves by a papermaking method, belonging to the technical field of reconstituted tobacco leaves. Background technique [0002] Papermaking reconstituted tobacco leaves are made from waste materials (tobacco fragments, tobacco powder, tobacco stems, waste tobacco leaves, waste shredded tobacco and tobacco powder sticks, etc.) A tobacco product with adjustable components and adjustable quality imitation tobacco leaves for cigarette production produced by a method similar to papermaking. On the premise that the tobacco industry continues to promote harm reduction and coke reduction technology, the use of papermaking reconstituted tobacco leaves in cigarette production will continue to increase. [0003] The production process of reconstituted tobacco leaves by the papermaking method involves the extraction of waste raw materials, making slurry fro...
