Problems solved by technology

Because tobacco waste such as tobacco stems and tobacco powder has short fibers and high content of non-fibrous components, low-concentration beating causes serious cutting and damage of fibers and non-fibrous components. High content, large material loss, low copying yield, poor sheet strength, low filling value, and high energy consumption in the beating process
However, if high-concentration refining is adopted to make the pulp meet the beating degree required for paper machine papermaking, the problems of excessive separation, brooming, and crushing of materials and fibers appear in the refining process, which affects the physical properties of tobacco sheets. Performance, and there are disadvantages such as large equipment investment and high energy consumption

Abstract

The invention belongs to the technical field of tobacco sheet manufacturing, and discloses a method for manufacturing tobacco sheets with a paper-making process and the tobacco sheets manufactured with the method. The method includes the steps that repulping processing is carried out on washed tobacco stems, washed tobacco powder and washed outer-fiber macrofiber pulp boards, and fiber stuff obtained after repulping processing is mixed and extracted; the concentration of a solid-phase mixture obtained after extraction is gradually reduced under the medium concentration conditions, and five-section soft defibrination processing is carried out to obtain materials used for manufacturing tobacco sheet base sheets; and then the paper-making process is adopted for manufacturing the tobacco sheet base sheets. According to the method and the tobacco sheets, the tobacco stems, the tobacco powder and the fiber stuff are mixed, and the protecting effect of large fibers on small fibers is adopted, so that the cutting effect and the damage effect on the fine tobacco powder in the defibrination process are reduced; the length of the fibers is better kept; the retention rate of the tobacco powder and packing is improved; the porosity of the tobacco sheets is improved; the physical performance of the tobacco sheets is improved; and the quality stability of the tobacco sheets is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of tobacco sheet preparation, and in particular relates to a method for preparing tobacco sheet by papermaking method and the prepared tobacco sheet. Background technique [0002] Tobacco sheet by papermaking method uses waste such as tobacco stems, tobacco leaf fragments and tobacco dust produced in the cigarette production process as raw materials, and uses wet papermaking method to prepare thin sheets close to tobacco leaves, which can be used in cigarette production. Paper-making tobacco flakes have low density, high filling value, good flexibility and processing resistance, high silk forming rate, good combustion performance, low tar release, and strong plasticity of the product, which has become one of the important ways for the comprehensive utilization of tobacco raw material waste . On the other hand, using tobacco waste to prepare paper-making tobacco sheets can make full use of tobacco raw materi...
