Device and method for producing crack-resistant no-delamination paper

Abstract

The invention relates to a device and method for producing crack-resistant no-delamination paper. The production device comprises a bottom net, a first guide roller group, a second guide roller group,a first forming net, a second forming net and a starch spraying mechanism, wherein both the first guide roller group and the second guide roller group are disposed above the bottom net, the first guide roller group is sleeved by the first forming net, and the first guide roller group is sleeved by the second forming net; first wet paper web is introduced on the bottom net through the first forming net, second wet paper web is introduced on the bottom net through the second forming net, and the starch spraying mechanism comprises a spray pipe and a preparing system for preparing starch into astarch liquid; and the preparing system is connected with the spray pipe, the spray pipe is disposed between the first guide roller group and the second guide roller group, and the spray pipe is arranged above the bottom net. The purpose that the starch liquid is sprayed evenly among paper layers is achieved through the starch spraying mechanism, then a subsequent high-temperature curing process is performed, and the bonding strength among the paper layers is improved through the obtained cured starch adhesive, so that the purpose of production of the crack-resistant no-lamination paper is achieved.

Description

technical field [0001] The invention belongs to the technical field of papermaking, and in particular relates to a production device and a production method of burst-resistant non-layered paper. Background technique [0002] With the continuous improvement of people's packaging requirements, people also have higher requirements for the strength of packaging boxes. A little damage will affect the damage of goods in the logistics process. Most of the packaging paper is formed by multi-layer molding and then compounded, and the compounding is not good It will affect the bonding strength between the paper layers, cause delamination, and seriously affect the use of paper. Therefore, the research on the production of burst-resistant non-delamination paper will become a very important research topic. Contents of the invention [0003] Therefore, the present invention provides a production device for break-resistant and non-delaminated paper. The production device realizes the pur...
