Embodiment 1
[0027] Embodiment 1. Adding method of papermaking method reconstituted tobacco leaf filler
[0028] In an exemplary embodiment of the method for adding fillers of reconstituted tobacco leaves in the papermaking process of the present invention, the method includes the following steps:
[0029] 1) Weigh 100kg of the filler used in the production of reconstituted tobacco leaves by the papermaking method (heavy calcium carbonate, the particle size range is 1 μm to 5 μm, and the sedimentation volume: 1.2ml / g to 1.9ml / g), and add it to a container filled with 400kg of water. In the mixing tank, stirring is carried out to form the filler (CaCO 3 ) in aqueous suspension;
[0030] 2) Weigh 120kg of the cellulose fibers used in the production of reconstituted tobacco leaves by the papermaking method (the compounding ratio of softwood pulp and hardwood pulp is 4:6), and dissociate with a hydropulper to form dissociated additional fibers slurry;
[0031] 3) Filler (CaCO 3 ) of the aq...

[0034] Example 2. Effects of Different Calcium Carbonate Types on the Pulping Effect of Cellulose Fibers
[0035] by Figure 1 The indicated filler (CaCO 3 ) Add method as comparative example, Figure II The filler of the present application shown (CaCO 3 ) adding method as an embodiment, according to Figure II The filler of the present application shown (CaCO 3 ) addition method, using light calcium carbonate (particle size range of 1 μm to 5 μm, sedimentation volume: 2.4mL / g-2.8mL / g) and heavy calcium carbonate (particle size range of 1 μm to 5 μm, sedimentation volume: 1.2 mL / g~1.9mL / g), compare the effect of heavy calcium carbonate and light calcium carbonate on the pulping effect of cellulose fiber (softwood pulp, hardwood pulp compound ratio is 4:6), the analysis results are shown in the table 1.
[0036] Table 1. Fiber test results
[0037]
[0038] From the results in the table above, it can be seen that the different types of calcium carbonate have no subst...
Embodiment 3
[0039] Example 3. Effect of adding fillers on pulping effect before cellulose fiber refining
[0040] by Figure 1 The indicated filler (CaCO 3 ) Add method as comparative example, Figure II The filler of the present application shown (CaCO 3 ) adding method as an embodiment, respectively according to Figure 1 and Figure II The method for slurry preparation, the fillers used in the two methods are heavy calcium carbonate (particle size range 1μm ~ 5μm, sedimentation volume: 1.2ml / g ~ 1.9ml / g), and the addition of the two methods Fiber pulp (combination ratio of softwood pulp and hardwood pulp is 4:6) was compared and analyzed for fiber structure, and the analysis results are shown in Tables 2-4.
[0041] Table 2. Fiber test results
[0042]
[0043] It can be seen from the results in the above table that after the process of the present invention, the brooming rate of the added fiber is increased from 0.377% to 0.515%, and the brooming rate is significantly increas...
