Abstract

The invention discloses a method of improving paper-making process tobacco sheet size retention rate and water filtering performance. The method includes: weighing cationic nano cellulose, adding water to prepare a cationic nano cellulose solution of 0.1-0.3% in mass concentration; weighing powdery guar gum, and adding water to prepare a guar gum solution of 0.1-0.3% in mass concentration; weighing powdery calcium carbonate, adding water to prepare a calcium carbonate suspension of 15-20% of mass concentration; in a condition that stirring speed is 800r / min, adding the calcium carbonate suspension accounting for 15-25% of absolute dry mass of the tobacco sheet size into paper-making process tobacco sheet size, stirring 30s, adding the guar gum solution accounting for 0.01-0.4% of the absolute dry mass of the tobacco sheet size, continuing stirring for 20s, adding the cationic nano cellulose solution accounting for 0.01-0.4% of the absolute dry mass of the tobacco sheet size. By the method, size water filtering performance and filler retention performance can be improved effectively, and tobacco sheets produced by the method are free of influence on smoking taste and high in safety.

Description

technical field [0001] The invention belongs to the technical field of paper-making tobacco sheet production, and in particular relates to a method for improving the retention rate and drainage performance of pulp in paper-making tobacco sheet production by using cationic nanocellulose and guar gum dual-element retention and drainage system . Background technique [0002] Paper-making reconstituted tobacco refers to the process of tobacco stems, tobacco powder and other tobacco raw materials in the cigarette production process, which are processed into a base (base paper) by means of the principles and techniques of papermaking, and then coated and dried to finally be made into a product similar to natural tobacco leaves. Flakes. Paper-making reconstituted tobacco is currently the most mainstream tobacco sheet production method in China. [0003] Because in the prior art, the raw material of paper-making method tobacco sheet mainly is tobacco stem, tobacco powder and part ...
