Abstract

The invention relates to the technical field of high-strength corrugated paper production, and particularly discloses a production process of high-strength corrugated paper. The production process comprises the following steps: S1, selecting and manufacturing corrugated paper raw materials; S2, crushing the raw materials of the corrugated paper; S3, removing impurities from the pulp obtained by crushing; S4, rolling the slurry into raw paper; S5, bonding the raw paper into corrugated paper; and S6, drying the glue on the corrugated paper. According to the invention, a fiber separator and an up-flow pressure screen are used to remove impurities from the pulp twice, so that the thoroughness of removal of impurities in the slurry is ensured, and the quality of the produced corrugated paper isensured; and meanwhile, the pulp reflowed by the up-flow pressure screen is further ground through a pulping machine, and the ground pulp is screened and utilized, so that reasonable utilization of resources is realized, waste of the resources is avoided, and the production cost of the corrugated paper is reduced.

Description

technical field [0001] The invention relates to the technical field of high-strength corrugated paper production, in particular to a production process of high-strength corrugated paper. Background technique [0002] High-strength corrugated paper is a board-like material bonded by liner paper and corrugated high-strength corrugated paper formed by processing corrugated sticks. It is generally divided into two types: single high-strength corrugated board and double high-strength corrugated board. [0003] When the existing corrugated paper is made, it is necessary to remove impurities and filter the slurry made of raw materials. In the process of removing impurities, the filtered raw materials are not used reasonably, resulting in a large amount of waste of corrugated paper raw materials, reducing the The production rate of corrugated paper increases the cost of corrugated paper production, and at the same time, the removal of impurities in the corrugated raw materials is no...
