Abstract
The present invention relates to a kind of paper technology and paper machine, be used to make high strength folder muscle brown paper.This technology is improved on former paper technology, increases a filter screen, is added with the machinery of knitting graticules behind first filter screen, also can adopt the graticules that weaves, and the graticules that weaves is after gluing is handled.Enter in the middle of the starching felt of first filter screen and second filter screen, the moisture content on the two-layer paper pulp is with the dissolving of the adhesive on the graticules, and through compressing, two-layer paper pulp is bonded on the graticules firmly, and technologies such as drying, rolling are promptly made high strength folder muscle brown paper.This process equipment is simple, and the folder muscle brown paper quality of manufacturing is good, and cost is low.
Description
The present invention relates to a kind of paper technology and equipment, be used to make high strength folder muscle brown paper.
Current because the raw material wood pulp anxiety of production paper causes the production unit insufficient raw material, and supply falls short of demand for the market paper, and product price floats again and again, its reason is removed and industrial expansion, outside the Pass the use amount increase has, also uses unreasonable relevant with paper.Resemble the cement package bags of selling in the market, be generally MULTILAYER COMPOSITE, paper using amount is big like this, the expense height.Though numb net composite packaging paper is also arranged, the production of this numb net composite packaging paper is to buy brown paper earlier, gluing on brown paper, and online then graticule is stained with a layer brown paper, complex manufacturing, cost height again.
Purpose of the present invention overcomes above shortcoming just, a kind of production technology that is used to make high strength folder muscle brown paper is provided, this technology is improved on former paper making equipment, need not wait and cause that to add graticules again behind the paper compound, and directly in the slurry paper-making process, promptly add graticules, produce reinforcement high strength brown paper.
The present invention is achieved in that former paper making equipment is the double filter screen that changes into of single filter screen, has the graticules that weaves between two filter screens.The grid net that graticules promptly is made into cotton thread or linen thread, the big I of grid decides according to the requirement of working strength.The graticules that weaves is earlier through the upper glue roller gluing, upper glue roller can be coated in adhesive on the graticules equably, graticules after gluing all is cylindric because of graticule, so need to push through two compression rollers, graticule is extruded into pancake, squeeze simultaneously and remove unnecessary adhesive, the gluing graticules that pushed leads by deflector roll, enters between the two-layer starching felt of two filter screens.The linear velocity of graticules is identical with two starching felt linear velocities, so just can be in the starching simultaneously of the both sides of graticules, the moisture content that contains in the paper pulp is moistening with adhesive, compress through tight pressure roller, paper pulp can be bonded at the graticules both sides firmly, former paper technology such as drying, rolling is promptly produced high strength reinforcement brown paper.With the folder muscle brown paper of this explained hereafter, what paper pulp was firm is combined in around the graticules, has strengthened the intensity and the anti-tear pulling force of paper, compare with raw ramie net composite sheet, be to improve on paper technology, materials are economized, and the adhesion of net and paper pulp is strong at all.
Accompanying drawing is a process chart of the present invention:
The present invention is described in detail below in conjunction with accompanying drawing:
Among the figure, 1 is first filter screen, and starching felt 13 is arranged on first filter screen, on the starching felt 13 paper pulp is arranged, and 2 is second filter screen, and former paper making equipment has has only first filter screen, and what have has two filter screens.Starching felt 12 is arranged on second filter screen, on the starching felt 12 paper pulp is arranged.The graticules that braiding is good (also can put into the equipment of knitting graticules in the middle of first and second filter screens, this equipment market is on sale) twists on the graticules dish 8, and this graticules can be used as the muscle of wrapping paper.Be added with the tension band-type brake on the graticules dish 8, can guarantee that screen cloth is smooth, through deflector roll 7 dredge exhibition and with upper glue roller 5 maintenance levels.Upper glue roller 5 can be coated in adhesive on the graticules equably, and 5 coating adhesives of upper glue roller can be polyvinyl alcohol.3 are following squeezing roller, and following squeezing roller is a drive roll, can drive first filter screen and upper glue roller 5 by chain 14, and last squeezing roller 4 be a driven voller, and upper and lower compression roller can become the graticules line pressure pancake, and can squeeze and remove excess adhesive, and at this moment online adhesive is seemingly dried but not dried.Graticules through setting is dredged exhibition by deflector roll 11 by dredging exhibition deflector roll 10, enters between the starching felt 12 of the starching felt 13 of first filter screen and second filter screen, and the linear velocity of graticules is identical with starching felt linear velocity.Paper pulp on graticules and the starching felt 13 is compound, cover by the paper pulp on the starching felt 12 of second filter screen again, moisture content in the paper pulp is moistening the adhesive on the screen cloth, two-layer paper pulp is in the graticules both sides, the graticules of adhering tightly, compress through tight pressure roller 6, two-layer paper pulp promptly is bonded on the fictitious graticule tightly, so increased the intensity and the anti-tear pulling force of paper.Thereafter identical with former paper technology, drying, technologies such as rolling are promptly made finished paper.
This technology is compared with the technology of original production fiber crops net extrusion coating paper, has reduced production routine and paper pulp consumption, and cost is low, and the papery flexibility is good.
