Embodiment 1

[0036] To compare the permeability of paper-making reconstituted tobacco leaf base sheets to the same coating solution produced by different production processes. The samples of reconstituted tobacco leaf substrates of three papermaking methods produced by different beating processes were obtained from the production line. Place the substrate sample in an environment with a temperature of 22°C ± 1°C and a relative humidity of 60% ± 3% for 48 hours to balance its moisture, select the flat and undamaged part of sample 1 and cut it into 6 pieces with a standard quantitative sampler 0.01m 2 of discs. Fold three pieces of cut circular paper with the front side up and three pieces with the back side up, respectively, to form a quarter fan shape, open from the middle to form a cone, put it into a glass funnel, and align the bottom of the glass funnel with the exit Place an Erlenmeyer flask filled with 50ml of clear water, use a pipette to absorb 10ml of the coating solution, use th...

[0041] To compare the permeability of different coating liquids in the same papermaking method of reconstituted tobacco leaf substrate. A sample of paper-making reconstituted tobacco leaf base sheet and three coating solutions with different formulations were obtained from the production line. The substrate sample is placed in an environment with a temperature of 22°C ± 1°C and a relative humidity of 60% ± 3% for 48 hours to balance its moisture. Select the flat and undamaged part of the sample and use a standard quantitative sampler to cut it into 6 sheets with an area of 0.01m 2of discs.

Embodiment 3

[0046] Detecting the dynamic process of coating liquid penetration in papermaking reconstituted tobacco leaf substrates. Samples of reconstituted tobacco leaf substrates and coating liquid samples obtained from the production line. The substrate sample is placed in an environment with a temperature of 22°C ± 1°C and a relative humidity of 60% ± 3% for 48 hours to balance its moisture. Select the flat and undamaged part of the sample and use a standard quantitative sampler to cut it into 4 sheets with an area of 0.01m 2 of discs. Fold three pieces of cut circular paper with the front side up and three pieces with the back side up, respectively, to form a quarter fan shape, open from the middle to form a cone, put it into a glass funnel, and align the bottom of the glass funnel with the exit Place an Erlenmeyer flask filled with 50ml of clear water, use a pipette to absorb 10ml of the coating liquid sample 1, quickly transfer all the coating liquid in the pipette into the funn...

Abstract

The invention discloses a determination method for the permeability of a paper-making reconstituted tobacco substrate coating liquid. The method includes the steps of: S01, cutting a smooth reconstituted tobacco substrate into round samples, performing folding and conducting opening from the middle to form cone, and putting the cone into a glass funnel; S02, using a pipette to suck 5-20ml of a coating liquid, transferring the coating liquid in the pipette all into the funnel, starting timing, letting the coating liquid gradually drip from the funnel into a conical flask, and taking out the conical flask 2-10min later; S03, mixing the solution in the conical flask uniformly, then detecting the turbidity, repeating the detection process and performing calculation to obtain the average turbidity T; S04, dripping a same volume of coating liquid directly into an equal amount of clear water, mixing the substances evenly, then performing detection to obtain turbidity T0, simultaneously detecting the clear water turbidity to obtain Tw; and S05, representing the permeability of the paper-making reconstituted tobacco substrate coating liquid as the permeability index X shown as the specification. The determination method for the permeability of a paper-making reconstituted tobacco substrate coating liquid provided by the invention has the advantages of simple operation and accurate measurement result.

Description

technical field [0001] The invention relates to a method for measuring the permeability of a coating solution of a reconstituted tobacco leaf base sheet by a papermaking method, and belongs to the technical field of tobacco analysis. Background technique [0002] The paper-making reconstituted tobacco technology uses tobacco stems, tobacco leaf fragments, and tobacco dust as raw materials, and uses papermaking technology to process products with tobacco flavor. Strong plasticity and other characteristics have been widely used in the tobacco industry. [0003] Coating solution is the most important component that affects the intrinsic quality of papermaking reconstituted tobacco leaves. After paper machine coating, the coating solution permeates and absorbs in the substrate, thus endowing papermaking reconstituted tobacco products with certain aroma characteristics. Therefore, the coating liquid permeability of the substrate is a very important index. Patents CN201410448887...
