Embodiment Construction

[0022] The present invention notices that when producing the pulp board containing water-absorbing resin, the paper is broken without hanging the net, because the excessively large gel-like water-absorbing resin particles cover the mesh in sheets after absorbing water, and the gap between the pulp fiber and the mesh wheel is cut off. direct contact. The gel-like water-absorbent resin particles that block the mesh are a form of covering rather than plugging. As long as this covering of the gel-like water-absorbing resin particles is sporadically dispersed, the pulp fibers will not be covered by the gel-like water-absorbing resin particles. A large area is separated from the screen wheel, the phenomenon of paper break due to hanging the net can be overcome, and the production of pulp board containing water-absorbent resin can be realized.

[0023] Specific embodiments of the present invention are illustrated in more detail below with reference to the accompanying drawings:

Abstract

The invention provides a pulp board machine for producing water absorbent resin-containing pulp boards, comprising a net part device, a squeezing device and a drying device. The net part device comprises a pulp flow box, a head box and a net wheel. The pulp board machine is characterized in that a water inlet end of the net wheel is provided with a water spraying device spraying water from inside to outside; a toothed roller is arranged at the inner side of the net wheel; a brush-carried roller is arranged at the outer side of the net wheel; and the position of the toothed roller is corresponding to that of the brush-carried roller. The pulp board machine solves the problem of paper breaking caused by that water absorbent resin obstructs screening during board manufacturing and can fully retain the reuse value of the water absorbent resin.

Description

technical field [0001] The invention relates to the field of papermaking, in particular to a pulp machine for producing pulp sheets containing water-absorbing resins. Background technique [0002] Paddle boards are semi-finished products for making various paper products. The production method of the paddle board is to input the raw pulp or regenerated pulp prepared by stock preparation and pulping into the headbox of the paper machine, hang the wire in the head box to form a pulp board, and then squeeze water in the pressing part and dehydrate in the drying part. Finished by calender, packed into flat pulp board or reel pulp board, handed over to paper products factory to produce various paper products. [0003] In the production of paddle boards, materials with different characteristics can be added to the pulp to produce synthetic pulp boards with different properties. To meet the different needs of customers. [0004] The joint action of water-absorbing resin and pulp...
