Since the other parts of the box forming system 5 are of conventional construction, they will not be described here.
The morphology of the superfine calcium carbonate crystal selected in the embodiment is chain or sheet, and as the superfine calcium carbonate has the characteristics of filling the concave and growing along the gaps, the fiber in the slurry is a porous loose material, so that the growth and adsorption positions of the superfine calcium carbonate can be provided; the cellulose nanocrystals are connected with adjacent fibers through bridging, so that the bonding between the fibers is increased, the bonding area is increased, and in addition, larger fibers can be embedded, so that the superfine calcium carbonate and the cellulose nanocrystals are added into the slurry, and a space network structure can be formed between the superfine calcium carbonate, the cellulose nanocrystals and the fibers in a self-assembled mode, and the strength and the bearing capacity of the corrugated paper are improved.
In the embodiment, the organic montmorillonite modified rosin size emulsion is adopted, and the positive charges carried by the emulsion are increased by cations carried among montmorillonite sheets, so that free negatively charged fibers are easily adsorbed, a tighter structure is formed between the free negatively charged fibers and a self-assembled space network structure, the stress concentration of corrugated paper is changed, and the physical property and mechanical property of the corrugated paper are improved.
In summary, compared with the ground paper box made of conventional corrugated paper, the ground paper box made of the high-strength compression-resistant corrugated paper of the embodiment has higher strength and compression resistance, so the inventor finds that when the ground paper box made of the high-strength compression-resistant corrugated paper of the embodiment is turned over, the tightening clamp can not only effectively avoid relative sliding in the process of turning over the upper cover, improve the packing efficiency of the corrugated paper box, but also maintain the surface of the upper cover of the corrugated paper box to be flat; when the conventional corrugated carton is inverted, it is found that a portion of the upper cover surface of the carton is pitted or even scored.
The above description is only of the preferred embodiments of the present invention and is not intended to limit the present invention, and various modifications and variations may be made to the present invention by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
