Problems solved by technology

[0005] The purpose of the present invention is to overcome the defects of the prior art, aim at the deficiency of the existing papermaking tobacco sheet production technology, overcome the serious loss of pulp fibers and fillers, low raw material utilization rate and waste water treatment in the existing papermaking tobacco sheet production process. To solve the defects of high quantity and processing cost, provide a method for the production of paper-making tobacco sheet to improve the retention of slurry and filler, so as to improve the utilization rate of raw materials, the ash content of the substrate and its coating rate, and reduce the cost of paper-making white water treatment. Method for improving retention of pulp fibers and fillers in the production of paper-based tobacco sheet

Embodiment 1

[0024] Refer to the company's paper-making tobacco sheet production technology and product formula, accurately weigh each tobacco raw material, and implement the separation of chemical components in the tobacco raw material according to the process parameters of the extraction section. The extracted tobacco residue is then passed through a refining process to make tobacco pulp. Add 12% dry weight of tobacco pulp, such as flax fiber and 8% unwrapped filler calcium carbonate, stir thoroughly and adjust to 0.8-1.5% finished pulp. Copy the film on the machine. recorded as a control sample. Determination of fiber and filler retention, substrate ash, bulk and liquid absorption. The measurement results are shown in Table 1.

Embodiment 2

[0044] The present invention is used for papermaking tobacco sheet production to improve the retention method of pulp fiber and filler, and its steps are as follows:

[0045] 1) According to the ratio of 0.01-0.20% by weight, add the natural potato starch of the coating agent and the filler into the reaction kettle, stir well and add deionized water with a total weight of 20-65%, and heat it to a temperature of 45 Stop stirring after -80°C, stop the reaction after the reactants thicken and form a mass, discharge the material, dry in a drying oven at a temperature of 120°C, and grind to 200-600 mesh after completion;

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

[0047] 3) After step 2) is co...

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...
