Problems solved by technology

[0005] In order to overcome the above-mentioned defects in the prior art, the purpose of the present invention is to provide a method for adding a novel fluffy additive to improve the air permeability and absorbency of the papermaking reconstituted tobacco base sheet, so as to overcome the disadvantages of the papermaking reconstituted tobacco base sheet produced by the prior art. The air permeability and absorptivity of the reconstituted tobacco leaf are low. The present invention is simple, feasible and low in cost. Under the condition of ensuring a certain tensile strength of the reconstituted tobacco leaf substrate, the air permeability and absorptivity of the reconstituted tobacco leaf substrate by the papermaking method are improved, thereby improving the The utilization rate of the coating liquid improves the combustion performance and suction performance, improves the taste, and achieves the effect of reducing coke and harm

Abstract

The invention discloses a method for preparing a paper-making reconstituted tobacco substrate with high air permeability and high absorptivity; a fluffy auxiliary agent is added into the paper-makingreconstituted tobacco substrate, and the adopted fluffy auxiliary agent is derived from agricultural wastes and has the characteristics of light weight, looseness and porosity. The fluffy auxiliary agent is prepared by soaking inorganic waste powder generated after agricultural biomass wastes such as straws, rice husks, barks and the like are subjected to power generation by a biomass power plantin sodium hydroxide, separating a solid phase and a liquid phase, and reacting the liquid phase with calcium hydroxide. The goal of improving the air permeability and the absorptivity of the paper-making reconstituted tobacco is achieved. Firstly, tobacco stems and tobacco powder which are subjected to leaching, solid-liquid separation and defibering are mixed with additional plant fibers and fluffy auxiliary agents to prepare pulp, and finally, the pulp is made into the substrate. By improving the air permeability and absorptivity of the paper-making reconstituted tobacco, the smoking performance of cigarettes is improved, the combustion performance is improved, the effects of reducing tar and harm are achieved, and a new method is provided for continuous industrial production of the paper-making reconstituted tobacco.

Description

technical field [0001] The invention belongs to the field of paper-making reconstituted tobacco leaves, and in particular relates to a method for preparing a paper-making reconstituted tobacco leaf substrate with high air permeability and high absorbency. Background technique [0002] Reconstituted tobacco leaf, also known as tobacco flakes, is an important raw material in modern tobacco manufacturing. It is a flaky material with similar performance to natural tobacco leaves, which is made by using the leftovers such as tobacco stems, broken leaves and tobacco powder produced in the cigarette production process through certain physical and chemical methods. important raw material. Compared with the roll pressing method and the thick pulp method, the reconstituted tobacco leaves of the papermaking method have the characteristics of lower density, relatively higher strength, good air permeability, high bulk, good combustion performance, small tar release, and high filamentati...
