Example Embodiment

[0023] Example 1

[0024] With reference to the company's paper-making tobacco sheet production technology and product formula, each tobacco raw material is accurately weighed, and the chemical components in the tobacco raw material are separated according to the process parameters of the extraction section. Then, the extracted tobacco residue is passed through a refining process to make tobacco pulp. Add 12% of the absolute dry content of the tobacco slurry to the external fiber, such as flax fiber and 8% unwrapped filler calcium carbonate, stir thoroughly and adjust the concentration to 0.8-1.5% of the finished slurry. Copy on the machine. Recorded as the control sample. Determine the retention rate of fibers and fillers, substrate ash, bulk and liquid absorption. The measurement results are shown in Table 1.

Example Embodiment

[0043] Example 2

[0044] The method of the present invention for the production of paper-making tobacco sheets to improve the retention of pulp fibers and fillers has the following steps:

[0045] 1) In accordance with the weight ratio of 0.01-0.20%, add the natural potato starch and filler as the wrapping agent into the reactor, stir well and add deionized water with a total weight of 20-65%, and heat to a temperature of 45 in this state. Stop stirring after -80°C, and finish the reaction after the reactants become thick and form a mass. Discharge the material and place it in a drying oven at a temperature of 120°C to dry, and crush 200-600 mesh after completion;

[0046] 2) According to the mixed slurry after refining, add the charge regulator to adjust the pulp fiber in proportion, and use the particle charge titrator to measure the zeta potential to -25~5mv; the charge regulator is alum. The amount of the charge regulator is between 0.05-0.25% of the absolute dry amount of the ...

Abstract

The invention relates to a method for improving the retention of sizing agent fiber and filler in production of tobacco sheets through the paper-making process. According to the technical requirements, natural potato starch is selected and used as a wrapping agent, and then the surface of the filler is wrapped or the filler is partially wrapped in the wrapping agent; a charge control agent is selected and used for regulating the charge on the surface of the sizing agent fiber, then the filler wrapped in the wrapping agent is added to a tobacco sizing agent, and production of the tobacco sheets through the paper-making process is conducted for improving the retention of the fiber and the filler. The method is applied to the production technology of the tobacco sheets through the paper-making process; by means of the method, the retention of the fiber and the filler in the sizing agent can be remarkably improved, loss of fine fiber and filler is reduced, the utilization rate of raw materials is increased, and the quality of the tobacco sheets is not affected. The method has the advantages that operation is simple, equipment is common and pollution is avoided.

Description

technical field [0001] The invention relates to the technical field of paper-making tobacco sheet production technology, and specifically discloses a method for improving the retention rate of pulp fibers and fillers in paper-making tobacco sheet production. Background technique [0002] Tobacco flakes by papermaking method use tobacco powder, tobacco stems, tobacco leaf fragments, waste tobacco leaves and other tobacco substances as the main raw materials. Chemical extraction and separation technology is used to separate the soluble chemical components of tobacco pulp, and then pulp and paper production technology is used to extract The final slag is copied into a substrate, and then the separated and extracted chemical components are reduced (such as coated) on the substrate and processed to form a tobacco sheet product. The production process of paper-making tobacco flakes mainly includes three parts: extraction and concentration, pulping and sheeting, and coating and dr...
