Abstract
The invention relates to a method for manufacturing paper used in tobacco cultivation by utilizing waste tobacco stalk. Waste tobacco stalk is fed into an extraction device to be extracted, then solid liquid separation is carried out, the obtained solid party is subject to pulping, the obtained tobacco stalk pulp is conveyed to a blending chest, 10-20wt% of long fiber wood pulp, 2-5wt% of water repellent agent and 15-20wt% of calcium carbonate filler are added, and then water is added for dilution, so as to obtain mixed size; and then the mixed size is added with water for dilution again and then is fed into papermaking equipment for papermaking and forming, and pre-drying is carried out to obtain paper web, and the paper web is coated and dried, thus obtaining the paper used in tobacco cultivation of the invention. The invention fully and comprehensively utilizes leftovers of threshing and redrying factory, and paper used in tobacco cultivation which not only has good heat preservation performance, good moisture-retention, good shading performance and good air permeability but also can promote growth of tobacco seedling, is degradable, is environmentally friendly and can substitute plastic film can be manufactured.
Description
Technical field
The invention belongs to the paper technical field, be specifically related to utilize the waste tobacco stem that produces in the production of cigarettes to make the method for paper used in tobacco cultivation.
Background technology
In tobacco threshing and redrying factory produces, can produce a large amount of cigarette leftover bits and pieces---offals.Contain 10～17% cellulose in the offal, this partly material still have higher value, fully fully utilizing these raw material resources, to come the high product of production added value be an important developing direction.
Tobacco is the warm crop of a kind of happiness, and tobacco cultivation has one tobacco seedling is transplanted to the process of vega, uses plastic sheeting to be incubated, to preserve moisture at present usually, to guarantee the normal development growth of cigarette seedling.But plastic sheeting shading, gas permeability are poor, and more seriously its is difficult for degraded, causes environmental pollution easily.Therefore, research and develop a kind ofly have insulation, preserve moisture, shading, gas permeability be all reasonable, and can promote that again the paper used in tobacco cultivation of the alternative plastic sheeting of tobacco seedling growth, degradable, environmental protection is very necessary.
Summary of the invention
The objective of the invention is to, there is problem of environment pollution caused at existing tobacco cultivation with plastic sheeting, fully fully utilize leftover bits and pieces---the offal of threshing redrying plant, manufacturing obtain a kind of not only have preferably be incubated, preserve moisture, shading, gas permeability, can promote the paper used in tobacco cultivation of the alternative plastic sheeting of tobacco seedling growth, degradable, environmental protection again.
The objective of the invention is to be achieved through the following technical solutions.
Utilize waste tobacco stalk to make the method for paper used in tobacco cultivation, manufacture method is as follows:
