Paper pulp dehydration equipment for producing high-strength base wallpaper and base wallpaper production technology thereof

Abstract

The invention discloses paper pulp dehydration equipment for producing high-strength base wallpaper and a base wallpaper production technology thereof. The base wallpaper production technology of thepaper pulp dehydration equipment for producing the high-strength base wallpaper comprises a pulping segment and a papermaking segment, wherein the papermaking segment comprises dehydration, drying, press polish, paper rolling, cutting and packaging. According to the paper pulp dehydration equipment for producing the high-strength base wallpaper and the base wallpaper production technology thereof,through a novel surface sizing technology, by adopting modified resin and a glycerine compounding technology, the strength and the flexibility of paper sheets are effectively improved, moreover, by adopting supercalendering in combination with a single-face coating technology for surface treatment, the surface fineness and smoothness of the base wallpaper are effectively improved, meanwhile, by arranging an adjustable cleaning mechanism, when a spiral paper pulp dehydrator is used for a long time to cause blocking for a filter screen, the filter screen can be cleaned conveniently and efficiently, the filter screen does not need to be detached, the efficiency of dehydrating paper pulp is greatly guaranteed, and the production and processing efficiency of an enterprise is improved.

Description

technical field [0001] The invention relates to the technical field of wallpaper base paper production, in particular to pulp dehydration equipment for high-strength wallpaper base paper production and a wallpaper base paper manufacturing process. Background technique [0002] The wallpaper base paper uses 100% bleached chemical wood pulp as raw material, uses free beating, light sizing, less fillers, and is made into paper on a fourdrinier paper machine. The wallpaper base paper is a roll paper with a quantitative ratio of 80 g / m2 or 90 g / m2. It requires high tightness and whiteness, and a certain degree of crack resistance, water resistance and wet strength. [0003] However, for wallpaper, the existing base paper has limited performance, so that the strength and surface properties of the produced wallpaper base paper often fail to meet the expected quality. , during dehydration, after long-term use of the external filter, impurities are likely to cause clogging, serious...

Problems solved by technology

[0003] However, for wallpaper, the existing base paper has limited performance, so that the strength and surface properties of the produced wallpaper base paper often cannot meet the expected quality. , during dehydration, after long-term use of the external filter, impurities are likely to cause clogging, seriously affecting the dehydration efficiency, and the filter is inconvenient to clean after clogging, and even the filter needs to be disassembled and cleaned, which seriously affects the Dehydration efficiency affects the efficiency of production and processing of enterprises. Therefore, we propose a pulp dehydration equipment for high-strength wallpaper base paper production and its wallpaper base paper manufacturing process
