Embodiment 1

[0028] A clean production process for producing corrugated medium paper using waste paper boxes,

[0029] In the leather fiber slurry pulping step, the recycled leather is pulped by a pulper, and then through the high-concentration deslagging step, the rough screening step, the low-concentration deslagging step, the fine screening step and the concentration step in sequence, to make a suitable Leather fiber pulp for papermaking, the pulping concentration of leather fiber pulp is controlled at 7-8%;

[0030] In the stripping step, the waste paper box is continuously conveyed through the conveyor belt, and the waste paper box is cut into strips by the slitting machine;

[0031] In the step of pulping waste paper, the waste paper box cut into strips is put into a large pulper, and the pulping is completed in the large pulper;

[0032] In the step of removing impurities and slag, the light slag floating on the upper layer of the large pulper is salvaged through the salvage net, a...

Embodiment 2

[0042] A clean production process for producing corrugated medium paper using waste cardboard boxes. The main steps, process parameters and advantages of this embodiment are the same as those of Embodiment 1, and will not be repeated here. The difference is that it includes the following steps,

[0043] Leather fiber slurry pulping step;

[0044] strip step;

[0045] waste paper pulping step;

[0046] Impurities and slag removal steps;

[0047] screening purification steps;

[0048] In the step of mixing petrochemical additives, the pure slurry is transported to the petrochemical reactor through the delivery pipeline, and the petrochemical additives are continuously and quantitatively injected at the turning point in the middle of the delivery pipeline. The flow rate of the pure slurry in the delivery pipeline with an inner diameter of 20-22cm is controlled at 8-10 m / min, the injection speed of petrochemical additives is 180-200 g / min, petrochemical additives include polyar...

Abstract

The invention discloses a clean production process for using waste paper boxes to produce corrugating medium paper. The process mainly comprises the steps of leather fiber sizing agent preparation, waste paper pulping, screening and purifying, blending of petrifaction addition agents, blending in a pipe, petrifaction, fibrillation, pulp preparation and net erection and shaping. By utilizing the waste paper boxes to produce the corrugating medium paper, the interweaving force and bonding force among fibers in recycled paper during paper manufacturing are enhanced, the strength and tenacity of the produced corrugating medium paper are better, the production resource is saved, the production process is clean and free of pollution, energy is saved, the environment is protected, and the production cost is low.

Description

technical field [0001] The invention relates to the technical field of production technology of corrugated medium paper, in particular to a clean production process for producing corrugated medium paper using waste paper boxes. Background technique [0002] With the development of the packaging industry, customers have higher and higher requirements for packaging paper. In order to protect their products and distinguish the difference from other customers in sales, many customers can give customers better visual effects to attract customers' recognition of products. We hereby invent striped kraft wrapping paper, which is used for packaging items. Because the paper has texture, it is not only beautiful and eye-catching, but also has anti-counterfeiting function, which is easy to win the love of customers and stimulate the sales of products. [0003] Using new materials such as wood, corn stalks, and wheat stalks to produce striped packaging kraft paper, the production process...
