Powder forming, coating, papermaking and mixing pulping method

Abstract

The invention provides a powder forming, coating and papermaking mixed pulping method. The method comprises the following steps of preparing raw materials of ultrafine powder, mixing the raw materials with water, and performing separation and extraction to obtain an extracting solution and filter residues; mixing the filter residue with the slurry, adding an auxiliary agent, fully and uniformly mixing to obtain a mixed slurry, and preparing a sheet base based on the mixed slurry; and concentrating the extracting solution to prepare a coating solution, coating the coating solution and the film base to prepare a coating sample, and drying the coating sample to obtain the finished base paper. Through ultrafine pulverization and crushing treatment of the raw materials, extraction efficiency of the raw materials can be effectively improved, the specific surface area and the pore volume fraction of the raw materials are improved, high coating amount loading is further achieved, uniformity of paper in the film base operation forming process is improved, and finally production and processing of high-quality raw paper are achieved. The process can be widely applied to the field of production and processing of various products such as recombinant tobaccos, cigarette paper, plant scented sheets, special functional paper, cigar sleeves, paper filter tip rod base paper and heating tobacco cigarette core materials.

Description

technical field [0001] The invention relates to the technical field of coating papermaking methods, in particular to a powder forming coating papermaking mixing pulping method. Background technique [0002] Paper-making reconstituted tobacco leaves are made of waste tobacco stems, tobacco leaf fragments, tobacco dust and other tobacco raw materials in the process of re-baking and cigarette production, and are processed through extraction, concentration, separation, beating, papermaking, drying, cutting and other processes. Excellent reconstituted tobacco leaves similar to natural tobacco leaves are used for cigarette filling and reused in cigarette production. With the development of cigarette industry technology and the improvement of consumers' demand for smoking quality of tobacco products, papermaking reconstituted tobacco has undergone several product quality upgrades. The first generation is used as filler: its original purpose is mainly to recycle tobacco processing e...

AI Technical Summary

Problems solved by technology

Due to the diversification and heterogeneity of the raw material sources of reconstituted tobacco leaves in the papermaking method, the extraction and beating process needs to face the problems of insufficient extraction and uneven beating, which makes the sheet base produced by papermaking show rough surface and unstable banner quantity , poor uniformity, large fluctuations in physical indicators, poor absorption of the substrate, and difficulty in loading the coating solution, and the finished product also shows rough surface, uneven coating, and coating rate higher than 40%. Basic characteristics of paper-making reconstituted tobacco leaves with product agglomeration and large fluctuations in processing resistance index
