Abstract

The invention relates to a method for increasing a retention rate of a sizing agent in paper-making reconstituted tobacco. The method comprises the steps that calcium carbonate is added into a tobacco fragment sizing agent with a certain beating degree to enable the calcium carbonate and the tobacco fragment sizing agent to be fully adsorbed to form a compound; the compound is wrapped by sodium alginate to form a larger flocculation body; modification and stability treatment are performed on the surface of the flocculation body by aluminum sulfate; the modified calcium carbonate and the tobacco sizing agent are mixed with the help of a multi-element composite retention and drainage system and then processed into the reconstituted tobacco through papermaking, squeezing, coating, drying and slitting. By means of the method for increasing the retention rate of the sizing agent in the paper-making reconstituted tobacco, the binding force of the modified calcium carbonate and the sizing agent is enhanced, the modified calcium carbonate and the sizing agent are not likely to run off, and the retention rate of the modified calcium carbonate and the sizing agent in the reconstituted tobacco is high.

Description

【Technical field】 [0001] The invention belongs to tobacco processing technology, and relates to the field of reconstituted tobacco leaf production by papermaking method. It is a method of firstly using tobacco debris slurry to absorb calcium carbonate to form a compound, then combining sodium alginate to coat and modify the compound, and finally using multiple retention aids A method for improving the pulp retention rate of reconstituted tobacco leaves in the papermaking process by using a rate aid system. 【Background technique】 [0002] Reconstituted tobacco leaves are also known as reconstituted tobacco leaves, tobacco flakes, homogeneous tobacco leaves, etc. Foreign countries began to study the use of paper-making reconstituted tobacco leaves in the middle of the last century. The domestic paper-making reconstituted tobacco industry developed and started relatively late, but the development speed and technological progress were relatively fast. It has a strong functional...
