Energy-saving and environment-friendly corrugated board production technique

Abstract

The invention provides an energy-saving and environment-friendly corrugated board production technique. The energy-saving and environment-friendly corrugated board production technique comprises the following steps that S1, adhesives are prepared; S2, a paper tube of raw paper is mounted on a paper holder, and the end of the raw paper is led out from the paper holder; S3, the led-out end of the raw paper is attached to a paper guide roller, and the raw paper is led onto a heating roller so as to be preheated; S4, the raw paper passing through the heating roller is conveyed onto a single side machine to be pressurized into a required corrugated paper core; S5, operation in the step S2 and operation in the step S3 are conducted on inner paper and face paper correspondingly, then the sides, facing the corrugated paper core, of the inner paper and the face paper are coated with the adhesives prepared in the step S1; S6, the paper core is clamped between the inner paper and the face paper, so that a semi-finished corrugated board is prepared, and the semi-finished corrugated board is dried through a conveying belt type drying box; and S7, the dried semi-finished corrugated board is cut into a finished corrugated board through a longitudinal-transverse cutting machine according to requirements. In the production process, the water-based adhesives are used, so that the environment is effectively protected, the glued corrugated board has excellent water resistance and is high in utilization rate and curing speed, and production efficiency is greatly improved.

Description

technical field [0001] The invention relates to the field of papermaking, in particular to an energy-saving and environment-friendly corrugated cardboard production process. Background technique [0002] Corrugated cardboard is a multi-layer adhesive body, which consists of at least one layer of corrugated core paper (commonly known as "pit sheet", "corrugated paper", "corrugated core paper", "corrugated core", "corrugated base paper") and a layer Cardboard (also known as "boxboard", "boxboard"). It has high mechanical strength and can withstand bumps and falls during handling. The actual performance of a corrugated box depends on three factors: the properties of the medium and paperboard and the construction of the box itself. [0003] At the same time, with the increase of logistics volume, the demand for corrugated boxes is also increasing. Corrugated boxes are made of corrugated cardboard, and the quality of corrugated cardboard directly affects the quality of corruga...

AI Technical Summary

Problems solved by technology

However, the strength of existing corrugated cardboard is not high, the damage resistance is poor, and it is not easy to stack, and the bonding strength and water resistance are not very satisfactory, which may easily cause the corrugated box to absorb moisture and become soft, the edge is degummed and warped, and deformed, resulting in product deterioration and damage.
