Problems solved by technology

[0004] Existing corrugated paper production mostly uses waste paper beating, the beating effect directly affects the quality of corrugated paper products, the existing beating device only uses heating and stirring for beating, the fibers in the waste paper cannot be completely broken, resulting in the fiber in the pulp The agglomeration phenomenon is more serious, and the corrugated paper produced is rough and has poor strength

Abstract

The invention discloses a moisture-proof and corrosion-proof corrugated paper production process and device, the moisture-proof and corrosion-proof corrugated paper is formed by bonding at least one layer of core paper and cardboard paper, the core paper is made of corrugated base paper through machining, the corrugated base paper is divided into a surface layer and a bottom layer, the surface layer is made of long fiber pulp, short fiber pulp and broken pulp of waste paper pulp, the bottom layer is made of short fiber pulp and waste paper pulp of waste paper pulp, and the preparation method of the corrugated base paper comprises the following steps: S1, pulping waste paper; s2, performing internal sizing treatment on the raw material slurry; s3, performing net feeding, squeezing and drying treatment on the raw material paper pulp, and then obtaining a base paper blank; and S4, sizing the surface of the base paper blank, and drying to obtain the corrugated base paper. According to the moisture-proof and corrosion-proof corrugated paper, the corrugated base paper of the moisture-proof and corrosion-proof corrugated paper is prepared from the waste paper pulp through a dual sizing process, and then the core paper machined from the corrugated base paper is bonded with the cardboard paper so that the prepared moisture-proof and corrosion-proof corrugated paper is high in machine strength and has good water resistance and corrosion resistance.

Description

technical field [0001] The invention relates to the field, in particular to a moisture-proof and anti-corrosion corrugated paper production process and a device thereof. Background technique [0002] Corrugated cardboard, also known as corrugated cardboard, is a multi-layer bonded body consisting of at least one layer of corrugated paper and a layer of cardboard (also called cardboard). It has good elasticity and extensibility, and also has high mechanical strength, which can withstand collisions and falls during handling. It is mainly used in the manufacture of cartons, the sandwich of cartons, and other packaging materials for fragile goods. Corrugated cardboard is made of native straw pulp and waste paper, which is made into a base cardboard similar to yellow cardboard, and then rolled into a corrugated shape through mechanical processing, and then glued to the surface of the cardboard with an adhesive such as sodium silicate. The actual performance of corrugated board d...
