Description

A kind of preparation technology for regenerating high-strength corrugated base paper
Technical field
The present invention relates to a kind of preparation technology and equipment for regenerating high-strength corrugated base paper slurry.
Background technology
In manufacturing enterprise of China, the accounting of corrugated board alreadys exceed more than eighty per cant, particularly in some coastal prosperities City, no matter outlet or the domestic packaging being required for for corrugated board, are that its pressure resistance the characteristics of corrugated board Degree is high, but the production of fluting medium there is also some problems, and such as 1, how to ensure the strength problem of recycled writing paper；2nd, how to solve Under strength problem, it is preferably minimized cost, ensure enterprise strives production operation；3rd, production technology how is made to reach simplification, and not Influence the quality of production.
The content of the invention
It is good so as to provide a kind of intensity height, stability present invention mainly solves the technical problem present in prior art, provide Source utilization rate is high, and technique is simple, the preparation technology of the good regeneration high-strength corrugated base paper of properties.
The technical scheme is that：A kind of preparation technology for regenerating high-strength corrugated base paper comprises the following steps：
A. pre-process：After the waste and old corrugated paper that collection is returned adds water, decomposed under hydrabrusher, and add Deinking agent, primary pulp is generated, wherein the ratio of waste and old corrugated paper and water is 1: 2；
Plus wood pulp c.：Straw pulp, wood pulp are added in paper pulp, generates mixed pulp, wherein, paper pulp and straw pulp, the ratio of wood pulp Example is 1: 0.3, straw pulp be by reed by grinding and with the mixed slurries of water, wherein, the ratio of straw pulp and water is 1: 4；
D screening purifications：The great impurity of mixed paper slurry internal ratio is removed in high concentration desanding device, is re-introduced into low dense remove The tiny grains of sand and impurity are removed in sand device, generate paper pulp；
E. drying strengthening agent is added：Drying strengthening agent is added in intermediate paper pulp, is dried between maintaining the temperature at 70 DEG C~80 DEG C Generation prepares high-strength corrugated base paper slurry, Substance 120m2~125g/m2, ring crush intensity index is 5.6Nm/g.
The beneficial effects of the invention are as follows：Organic efficiency is high, saves production cost, can carry out industrialized production.
Embodiment
