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 of table 4: (1) select 200 order 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 15...

Embodiment 2

[0045] Select 200 mesh sheet-shaped calcium carbonate, join in the mixed slurry of tobacco flakes by 10% of raw material consumption, after stirring for 30 minutes under the powerful electromagnetic stirrer; After diluting the anion accelerant 10 times, press 0.3% consumption respectively Add it into the slurry and stir evenly, then dilute the guar gum to 0.1% concentration, add 0.15% 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.

Abstract

The invention discloses a method for improving sheet quality by increasing retention of a filler calcium carbonate in a sheet, belonging to the technical field of tobacco sheets. The method adopts thefollowing technical measures: (1) selecting nonsphericity as the grain shape of the calcium carbonate through an electron microscope; (2) controlling the granularity between 125 meshes and 400 meshes; (3) ensuring the addition of the filler calcium carbonate to be 7-12% of the total weight of mixed slurry; (4) adding guar gum accounting for 0.04-0.2% of the total weight of the mixed slurry into the slurry to serve as a retention aid; and (5) adding an anion catcher accounting for 0.1-0.8% of the total weight of the mixed slurry into the slurry. The method features effective measures and obvious generated technical effects, solves the technical problems and can improve the retention of the filler calcium carbonate in the sheet and the sheet quality.

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...
