Problems solved by technology

[0005] Although studies have shown that the addition of calcium carbonate and the use of auxiliary agent guar gum will have a significant impact on the performance of the reconstituted tobacco paper base, but the mechanism of the impact is not clear. Is the compatibility mechanism of the auxiliary agent and calcium carbonate reasonable? Excessive or improper use of tobacco will bring many uncertain factors to the tobacco sheet paper base, so there is a lack of stable, feasible and effective technical solutions in specific promotion and application.
The research on how to choose and determine the specific additive technical scheme and the corresponding application of the additive guar gum on the basis of the additive technical scheme is mostly at the stage of experience accumulation and imagination, and there is a lack of systematic and reasonable analysis. and research, rarely reported in the prior art

Embodiment 1

[0022] Example 1 Preparation of reconstituted tobacco leaf paper base by conventional method

[0023] (1) Dipping and extracting tobacco stems and tobacco powder respectively;

[0024] Dipping and extracting tobacco stems and tobacco powder respectively. The conditions for the steeping and extraction of the tobacco stems are that the ratio of solid to liquid is 1:7 (mass ratio), the extraction temperature is 60°C, and the extraction time is 100 minutes (min); the conditions for the steeping and extraction of the tobacco powder are that the ratio of solid to liquid is 1: 10. The extraction temperature is 70°C, and the extraction time is 60 min; the extracts of tobacco stems and tobacco powder obtained after the impregnation treatment are mixed according to a volume ratio of 1:1, and then conventionally evaporated and concentrated to obtain a coating liquid; after the impregnation treatment, the tobacco stems, Tobacco solids are used for refining.

Embodiment 2

[0032] The particle size distribution of embodiment 2 calcium carbonate particles

[0033] Take calcium carbonate powder, add water and be mixed with the calcium carbonate solution that the mass percentage concentration is 0.0016%, carry out particle size analysis, the analysis result of calcium carbonate particle size distribution sees figure 1 .

[0034] attached by figure 1 It can be seen that calcium carbonate for papermaking itself is not a spherical particle, and its diameter does not represent an absolute diameter in the usual sense. Integral curves, where the diameter can only be the statistical mean of all changing values. The particle size value is not unique, it is related to the instrument and statistical method used for measurement. No matter what kind of particle size analyzer (laser or sedimentation) is used, it is impossible to measure the distance between two points connecting the particle surface through the center of gravity, so the measured particle si...

[0043] Example 3 Effect of adding different amounts of guar gum on the quality of reconstituted tobacco paper base

[0044] Prepare the reconstituted tobacco leaf paper base according to the steps in Example 1, wherein in step (4), add the tobacco mixed slurry to tap water to prepare a tobacco slurry suspension with a solid content of 0.5 wt.%, disperse evenly, and add to it under low-speed stirring Calcium carbonate aqueous solution (concentration is 20g / L, stir the solution to make it evenly mixed), so that the final mass percentage of the added calcium carbonate in the mixed slurry is 50%. Stir for 30 seconds, add the guar gum suspension, continue to stir for 1 minute, and quickly make a tablet. The other steps are the same as in Example 1. The amount of guar gum added is increased from 0% to 1.5% (based on the final mass percentage of guar gum in the mixed slurry), and a variety of reconstituted tobacco leaf paper bases are prepared, and thin paper is obtained after the ...

Abstract

The invention discloses a method for adding calcium carbonate to improve the quality of a reconstituted tobacco leaf paper base and the reconstituted tobacco leaf paper base, belonging to the technical field of cigarette production. The method for adding calcium carbonate to improve the quality of the reconstituted tobacco paper base of the present invention includes the steps of soaking and extracting tobacco stems and tobacco powder, refining, beating, sheeting, pressing and drying, wherein in the step of sheeting, adding Calcium carbonate and 0.05-0.5% guar gum account for 10-70% of the mass percentage of tobacco raw material pulp. Studies have shown that after adding the above appropriate proportions of calcium carbonate and guar gum, the tensile index, tear index, and air permeability of the prepared reconstituted tobacco leaf paper base are significantly improved, and the overall liquid absorption performance of the reconstituted tobacco leaf paper base is increased. The tar content, CO content, and total particulate matter content of the sheet paper base are significantly reduced, which can better play the role of reducing tar and harm of reconstituted tobacco leaves, effectively improve the comprehensive performance of tobacco sheets, and improve the operation performance and effectiveness of the reconstituted tobacco leaf production line.

Description

technical field [0001] The invention belongs to the technical field of cigarette production, and in particular relates to a method for adding calcium carbonate to improve the quality of a reconstituted tobacco leaf paper base and the reconstituted tobacco leaf paper base. Background technique [0002] The production of reconstituted tobacco leaves by the papermaking method means that the tobacco stems, tobacco powder and some low-grade tobacco leaves in the cigarette production process are first processed into a base sheet (base paper) according to the papermaking method, and the base sheet is coated and dried, and finally made into a close An advanced reconstituted tobacco production process in which thin slices of natural tobacco leaves are applied to cigarette production. A certain amount of fillers are usually added in the production of paper-based tobacco sheets to increase the ash content of the paper base and improve other physical properties, such as liquid absorptio...
