Embodiment

[0012] Example: A production process of cotton paper, using long-fiber wood pulp to be disintegrated by a hydraulic crusher and adding chemical additives to make raw pulp, and then through a toothed disc deflaker and a refiner connected in series with a low-current semi-viscous beating , the beating concentration of the beater used is 4.2-5.5%, and the beating ampere is 46-58A; after the beating is completed, the pulp should be mixed, and 1% whitening agent should be added and filtered through a 90-mesh screen, and it should be evenly matched with the above-mentioned slurry; the above-mentioned mixed slurry should be copied After the paper is formed and dried, it is taken up by the rewinder, and the broken paper is detected in the drying and winding process. Please refer to the specific operation figure 1 .

[0013] Pulp forming includes pulping process, high-efficiency sand removal process, high-low-consistency high-level overflow and paper forming. The pulping process is co...

Abstract

The invention discloses a production process for cotton paper, which comprises the following steps of: digesting long fibered wood pulp by using a hydraulic breaker, and adding chemical aids to prepare primary pulp; serially connecting a fluted disc type deflaker and a fiberizer, pulping in a semi-cohesive state at low current, wherein the pulping concentration of the fiberizer is 4.2 to 5.5 percent and the pulping ampere is 46 to 58A; compounding the pulp after the pulping is finished, adding 1 percent of brightener, filtering with a 90-mesh screen, and uniformly compounding with the pulp; and performing papermaking on the mixed pulp, drying, reeling by using a re-reeling machine, detecting broken paper in the drying and reeling procedures, digesting and defibering the detected broken paper, and refluxing the broken paper to the pulp compounding procedure. The cotton paper prepared by the process has the advantages of uniform fibrous tissues, flat and smooth paper surface and small aspect ratio.

Description

technical field [0001] The invention discloses a production process of tissue paper, belongs to the technical field of papermaking process according to the International Patent Classification (IPC), and in particular relates to the processing process of special paper for high-grade packaging or high-grade printing. Background technique [0002] Cotton paper is a kind of special paper with extremely high toughness, excellent water and moisture absorption, air permeability and elasticity. Its paper is tough and white, thin and soft, and has strong tensile strength. It is non-toxic, environmentally friendly and durable. , delicate, anti-corrosion and anti-moth, strong ink absorption, not easy to change color, long-lasting, can be preserved for a long time, and become paper for glass products, precision instruments, tea packaging, food and wine packaging, and other various crafts , calligraphy and painting, books, handicraft packaging and other high-end commodity paper in variou...
