Detailed description of the invention
The production method of a kind of low grammes per square metre copy paper, comprises the following steps:
(1) take softwood pulp 200 parts and use hydropulper shredded paper, then pull an oar with fiberizer；
(2) take the making beating of Deinking Pulp 800 parts fiberizer, be heated to 80 DEG C, when being then cooled to 50 DEG C,
Adding bleaching powder 50 parts to bleach, and be stirred in bleaching process, mixing time is 0.5
Hour；
(3) softwood pulp of step (1) and the Deinking Pulp of step (2) are sent into slurry compounding machine with slurry,
And be simultaneously introduced dispersant 10 parts, antifungus agent 15 parts, preservative 15 parts, defoamer 10 parts and
Yeast powder 10 parts, and stir 15 minutes, then sealing and standing, time of repose is 5 hours, then
It is pumped into and destroies forebay and carry out copy paper；
(4) mixed slurry output carries out paper membrane molding, is dehydrated, dries and gluing；
(5) by the mixed slurry after gluing according to a conventional method with supercalender superpressure ornamenting, cut paper is used
Machine is cut into Xiao Zhang.
Described fiberizer is Austria's An Deli hereby fiberizer.Germany's Fu Yite shaking is used when stirring
Device.Single row type drying cylinder is used when drying.
Count by weight before the step (1), hemicellulase 20 parts, cellulase 5 parts,
Xylanase 5 parts, pectase 5 parts and 60 parts of water；Each component is weighed by above-mentioned formula, first will fruit
Glue enzyme water dissolution, adds dimension element enzyme and xylanase, stirs 20 with the rotating speeds of 30 revs/min
Minute, then hemicellulase is added 5 parts of Radix Aconiti Lateralis Preparatas, 10 parts of Rhizoma Dioscoreaes, 10 parts of Fructus Crataegis, 10 parts of burnt wheats
Bud and 10 parts of Pericarpium Citri Reticulataes are pulverized together and are mixed thoroughly, and last and above-mentioned gained liquid mixing, with 50 revs/min
Rotating speed stir 40 minutes, obtain described making beating enzyme preparation.In described step (3), first will step
Suddenly the Deinking Pulp of the softwood pulp of (1) and step (2) and dispersant, antifungus agent, preservative,
Defoamer is put into steamer and is evacuated to 2.0 × 10-8Torr, is adjusted to 80 DEG C of bakings by steaming kettle temperature,
Steamer internal gas pressure is raised to 2.5 × 10-7After Torr, toast 2 hours, to pot internal gas pressure return to 2.2 ×
10-8Baking is closed after Torr；It is finally cooled to room temperature, opens steamer and add the making beating enzyme of step (2)
Preparation, is then shut off steamer, steamer is evacuated to air pressure to 2.3 × 10-8Torr；Then steaming is opened
Pot takes out and to send into slurry compounding machine with slurry.
Owing to containing Plant fiber and other fibers in raw material, this project making beating enzyme has selected a kind of papermaking
Pull an oar special composite biological enzyme preparation, including cellulase, hemicellulase, xylanase,
Pectase etc..The specificity of enzyme makes them become the uniqueness that can be oriented modification in paper technology
Instrument, can process for the various fibers in raw material.Cellulase is used for processing cellulose, and half
Cellulose is for processing the hemicellulose that xylan is constituted with mannan, and pectase is used for decomposing pectin
Matter.It has been investigated that the making beating enzyme that this project uses can be directionally altered selected under particular circumstances
Raw material, processes preferably under neutrallty condition.Making beating enzyme is used for the pretreatment before slurry polishing, Ke Yiyou
Change slurry properties, beatability can be improved.The making beating enzyme that in terms of microcosmic, this project uses can
To change the character of fiber finer cell wall, make cell wall become lax, the internal easily layering of cell wall simultaneously or
Swollen, has pliability after making fiber wire-dividing broom purification.The making beating that in terms of macroscopic view, this project uses
Fiber surface can be modified by enzyme, breaks up fiber ends, promotes fibre swelling, simultaneously
Fiber surface and the hydroxyl of end and carboxyl are increased, thus the adhesion between reinforcing fiber, reach
Raising to papery.Pulp fiber after biology making beating ferment treatment is respectively provided with the sub-wire become apparent from
Brooming, the beating degree of slurry and weight in wet base are easier to improve, and can consume the raising of substantial amounts of electric energy and beat
Slurry degree improves beating degree and the weight in wet base of slurry, has saved substantial amounts of electric energy.
Use Austria's An Deli hereby fiberizer during refining process and carry out defibrination, such defibrination
Machine, it is possible to make the abundant fibrillating of long fibre, increases the freedom of slurry, controls the moisture of slurry well,
Improving refining pulp quality, beating degree and weight in wet base all can reach requirement.The wet end furnish that this project uses is
The low grammes per square metre proportioning of suitable production found after many suboptimization, is the softwood pulp with 20% and 80%
Deinking Pulp is that proportioning copies copy paper.This project have employed sophisticated equipment and carries out copy paper.Paper machine process uses
Being DCS Automated condtrol, be a kind of distributed automation control system, its equipment is mainly by diluting
Plain boiled water flow box Germany Fu Yite shaking device, single row type drying cylinder etc. forms.Greatly reduce artificial, carry
High yield quality, reduces steam consumption.Workshop have employed a set of save all, recycles water money
Source.First remove the long stuff of waste water with screen cloth, reclaim plain boiled water by save all and follow
Ring utilizes, and reduces water consumption and discharge, improves environmental requirement.
Use this method that prepared paper is measured:
| Yield rate | 97% |
| Water consumes | 220t/t paper |
| Power consumption | 1800kWh/t paper |
| The steam consumption | 3.2t/t paper |
Prepared paper carries out remaining according to GB GB/T 1911-2011 the mensuration of performance, is superior to GB
GB/T 1911-2011。
