Method for preparing regenerated fruit cultivating bagging outer bag paper by using waste fruit cultivating bagging paper

Abstract

The invention provides a method for preparing regenerated fruit cultivating bagging outer bag paper by using waste fruit cultivating bagging paper. The method comprises the following steps: cutting up the recycled waste fruit cultivating bagging paper, then adding boiling water, adjusting pH value, adding Al2(SO4)3, soaking, pulping, adding carbon black powder and grinding, thus obtaining paper pulp A; injecting the paper pulp A into a machine chest A, storing paper pulp prepared from fiber raw materials in a machine chest B, respectively adding fillers, sizing agents, water repellent agents and wet strength agents to the machine chest A and the machine chest B and uniformly stirring; and making and forming paper by using the paper pulp in the machine chest A and the machine chest B, laminating, forming, squeezing, dewatering and drying. The method has the advantages that the usage amount of raw wood pulp can be greatly saved, after pulp grinding treatment, the binding force between the carbon black and fibers in the paper pulp is still strong, as long as little carbon black is added, the high non-transparency requirements can be satisfied, and therefore, the problem that when lots of carbon black is applied in in-pulp dyeing, poor working environments of production workshops, the low utilization rate of the carbon black, the high production cost and the like are caused, is solved.

Description

technical field [0001] The invention relates to a method for preparing outer bag paper for fruit-growing bagging paper, in particular to a method for preparing outer-bag paper for re-growing fruit bagging paper by using waste fruit-growing bagging paper. Background technique [0002] With the improvement of people's living standards, while the demand for fruits continues to increase, higher requirements are also put forward for their quality. Fruit bagging cultivation technology is one of the advanced fruit tree cultivation technologies for producing high-quality, high-grade, brand-name, pollution-free and green fruits. It can increase the smoothness of the fruit surface, ensure bright color, improve the high-quality rate of fruits, and prolong the preservation period of fruits. effect. More and more orchards have gradually applied fruit bagging cultivation technology. According to estimates, the market price of bagged apples per kilogram is 1.5 to 2.5 yuan higher than that...

Problems solved by technology

The way fruit growers deal with these waste fruit growth bagging paper is to discard them in the orchard when picking the fruit, and to burn them with fire, which not only affects the soil quality and farming environment of the orchard, but also causes great environmental pollution. More than 2 million tons of pulp are needed to use bagging paper for fruit growth, which is a great waste of resources and is not conducive to the needs of sustainable development

[0004] Some fruit growers consider reusing the fruit-growing bagging paper directly, but found that the effect of the secondary-used fruit-growing bagging paper on fruit quality is significantly weakened, mainly because the use environment of the fruit-growing bagging paper is a completely open natural environment. During the 3 months of fruit growth and development, the fruit bagging paper needs to withstand the combined effects of wind, sun, rain and other complex climates on the tree, so the paper will be deformed and brittle when picking the bag Even some damage occurs, which reduces the air permeability, shading, tensile strength, water resistance, softness and other indicators that have a decisive impact on fruit quality.

At present, the research on the utilization technology of the fiber resources of the fruit bagging paper used in the orchard is still blank in China.
