A method for determining the base absorbency of reconstituted tobacco leaves by papermaking method
A technology for reconstituted tobacco leaves and reconstituted tobacco, which is applied in the directions of tobacco, tobacco processing, tobacco preparation, etc., can solve the problems such as the inability to quantitatively evaluate the absorbency of the reconstituted tobacco leaves by the papermaking method, and achieves the effect of simple operation.

Embodiment 1
[0018] (1) Cut the reconstituted tobacco leaf sample to be tested into a long strip with a width of 100×15mm, draw a scale line at one end of the strip 10mm from the edge, and place it in a constant temperature and humidity box with a relative humidity of 50% and a temperature of 23°C Balance the moisture for 24 hours, and weigh and record the samples with balanced moisture respectively;
[0019] (2) Hang the sample with balanced moisture vertically on the scale with the scale line, the reference line is aligned with the 0 scale line of the scale, one end is immersed in the solution for 4min, 8min, 12min, and then the sample is separated from the solution and allowed to stand 1min, read the highest and lowest scales of the sample suction position, take the average value as the sample suction height, the results are shown in Table 1 below:

Embodiment 2
[0026] A method for measuring base absorptivity of reconstituted tobacco leaves by papermaking method, the steps are:
[0027] (1) Cut the reconstituted tobacco leaf sample A to be tested into long strips with a width of 100×15 mm, a total of 20 samples, and draw a scale line 10 mm from one end of the strip for each sample (such as figure 1 shown), place in a constant temperature and humidity chamber with a relative humidity of 50% and a temperature of 23°C to balance the moisture for 24 hours, and weigh and record the sample with balanced moisture;
[0028] (2) Hang the sample with balanced moisture vertically on a scale with a scale line, align the reference line with the 0 scale line of the scale, immerse one end in the solution for 8 min, then separate the sample from the solution and let it stand for 1 min;
[0029] (3) Read the highest and lowest scales of the sample suction position, take the average value as the liquid suction height of the sample, and weigh the sample...
Embodiment 3
[0033] A method for measuring base absorptivity of reconstituted tobacco leaves by papermaking method, the steps are:
[0034] (1) Cut the reconstituted tobacco leaf sample B to be tested into long strips with a width of 100×15 mm, a total of 20 samples, and draw a scale line 10 mm from one end of the strip for each sample (such as figure 1 shown), placed in a constant temperature and humidity chamber with a relative humidity of 48% and a temperature of 22°C to balance the water for 24 hours, and weigh and record the water-balanced sample;
[0035] (2) Hang the sample with balanced moisture vertically on a scale with a scale line, align the reference line with the 0 scale line of the scale, immerse one end in the solution for 8 min, then separate the sample from the solution and let it stand for 1 min;
[0036](3) Read the highest and lowest scales of the sample suction position, take the average value as the liquid suction height of the sample, and weigh the sample mass after...
