Problems solved by technology

[0002] In the existing technology, the research level of tobacco processing technology in my country's paper-making tobacco sheet technology is still relatively low, and most of them are still in the stage of experience accumulation and imagination, so that there are still many uncertain factors in the process technology, and there are still many The technical points that need to be optimized, the research on the wet end chemistry of papermaking still needs to be deepened

Embodiment 1

[0040] Select 200 mesh flake-shaped calcium carbonate, join in the mixed slurry of tobacco flakes by 7.5% of raw material consumption, after stirring for 30 minutes under the strong electromagnetic stirrer; Dilute the anion trapping agent 10 times and press 0.2% consumption respectively Add to the slurry and stir evenly, then dilute the guar gum to 0.1% concentration, add 0.08% into the slurry and stir evenly; according to 65±3g / m 2 Quantitatively copy the film and test its ash value, filler retention rate, and water absorption performance. Compared with the original process of 800 mesh.

[0042]

[0043]As can be seen from the data in Table 4: (1) select 200 mesh calcium carbonates for use, when the add-on is 7.5%+guar gum 0.08%+anion trapping agent 0.2%, the retention rate is 30.5%, which is higher than the original process retention rate. The sticking rate has been improved by 154.2%. (...

Abstract

The invention discloses a method for improving the retention rate of filler calcium carbonate in a sheet and improving the quality of the sheet, and belongs to the technical field of cigarette auxiliary material papermaking tobacco sheet. The method for improving the retention rate of filler calcium carbonate in the sheet and improving the quality of the sheet adopts the following technical measures: (1) select the crystal grain shape of calcium carbonate to be non-spherical grain by electron microscope; (2) control the particle size at 125 Mesh to 400 mesh; (3) The amount of filler calcium carbonate added is 7% to 12% of the total weight of the mixed slurry; (4) Add 0.04% to 0.2% of the total weight of the mixed slurry to the slurry (5) adding 0.1% to 0.8% of anion scavenger accounting for the total weight of the mixed slurry in the slurry. The method of the invention has effective measures, produces remarkable technical effects, solves technical problems, can increase the retention rate of filler calcium carbonate in the flakes, and can improve the quality of flake products.

Description

technical field [0001] The invention belongs to the technical field of papermaking tobacco sheet as an auxiliary material for cigarettes, and in particular relates to a method for increasing the retention rate of filler calcium carbonate in papermaking tobacco sheet, thereby improving the quality of the sheet. Background technique [0002] In the existing technology, the research level of tobacco processing technology in my country's paper-making tobacco sheet technology is still relatively low, and most of them are still in the stage of experience accumulation and imagination, so that there are still many uncertain factors in the process technology, and there are still many The technical points that need to be optimized, and the research on the chemistry of the wet end of papermaking still needs to be in-depth. Through the analysis of the quality of paper-making tobacco flakes in the same industry, we found that the imported Modi flakes not only have pure smoke aroma, but al...
