Production and manufacturing method of printing and packaging coated paper

Abstract

The invention relates to a production and manufacturing method for printing and packaging coated paper, and a production and manufacturing device for printing and packaging coated paper is used. The production and manufacturing device for printing and packaging coated paper comprises a bottom plate, a repulping mechanism and a grinding and screening mechanism, the repulping mechanism is arranged above the middle of the bottom plate and installed on the grinding and screening mechanism, and the grinding and screening mechanism is installed in the middle of the upper end face of the bottom plate. The problems that an existing packaging copper paper producing and manufacturing device cannot smash raw materials before pulping, so that paper pulping is difficult, the pulping efficiency is low, the raw materials cannot be ground into powder during pulping, the quality of paper pulp is affected, and then the smoothness and fineness of the surface of manufactured copper paper are affected can be solved. The problems that residues of pulping raw materials are doped in the paper pulp, the purity of the paper pulp is influenced, and the quality of finished copper paper is influenced due to the fact that the ground paper pulp cannot be fully stirred and screened by an existing packaging copper paper producing and manufacturing device can also be solved.

Description

technical field [0001] The invention relates to the technical field of papermaking, in particular to a method for producing printed and packaged coated paper. Background technique [0002] Coated paper, also known as printing coated paper, is made by coating a layer of white paint mainly composed of silicon dioxide on the surface of the base paper and processed by super calendering. two kinds. Coated paper is characterized by its smooth surface, high whiteness, and good ink absorption and ink retention. It is mainly used for offset printing and gravure printing with fine screen lines, such as high-end picture albums, calendars, books and periodicals, etc. The disadvantage is that the powder is easy to stick and fall off after being exposed to moisture, so it cannot be stored for a long time. To put it simply, coated paper is made of ordinary paper. According to the papermaking process, the raw materials for making paper such as wood or crop straw need to be pulped, modula...

Problems solved by technology

[0005] The invention can solve the problem that the existing packaging copper paper production equipment cannot break the raw materials before refining, which leads to difficulties in paper refining, low refining efficiency, and the inability to grind raw materials into powder during refining, which affects the quality of pulp and then affects the production process. The smoothness and fineness of the surface of the copper paper can also solve the problem that the existing packaging copper paper production equipment cannot fully stir and sieve the ground pulp, which will cause the residue of pulping raw materials to be mixed in the pulp, which will affect the purity of the pulp, and then will Problems Affecting the Quality of Finished Copper Paper
