Description
Technical field
The present invention relates to the manufacturing process that a kind of high white ring protects highmulti paper, belong to pulp technology for making paper.
Background technique
Currently, existing whiteness largely uses 100% lumber fibre to produce in the paper of 85%ISO or more, to natural resources
Consumption it is big, it is both uneconomical, also not environmentally.With being increasingly enhanced for national environmental consciousness, green is pursued, environment-friendlypaper paper product has become
For a kind of propensity to consume of fashion.Paper products are produced using pulp from decoloured waste paper, the consumption to lumber fibre is reduced, is a kind of ring
It protects, expanding economy trend.Environmentally friendly pulp from decoloured waste paper paper products have become consumption mainstream in countries such as Japan, West Europe.Existing skill
Art is low using the paper products whiteness of a large amount of pulp from decoloured waste paper production, and printing color is low and deep, and color reducibility is bad, it is difficult to meet people
Esthetic requirement.
Summary of the invention
The purpose of the present invention is in view of the above problems, the present invention is furnished with a small amount of needlebush using pulp from decoloured waste paper using main
Bleached sulphate chemical pulp, production improve product whiteness by toning, and product whiteness is high, bulk is good, and color reducibility is good,
It can be used as manufacturing notebook, printing books etc..
In order to achieve the above object, the technical solution adopted by the present invention is that: a kind of high white ring protects the manufacturing process of highmulti paper,
Including using needlebush bleached sulphate chemical pulp, pulp from decoloured waste paper to remove by mashing underflow sieve with slurry, condiment, punching slurry, desanding
Gas fine screen, wet end dehydration forming, squeezing, preceding drying, top sizing, rear drying, soft calendaring, batches, rewinding, the techniques such as packing
Step,
(1) pulp from decoloured waste paper matches: 10# waste paper 70%, 37# waste paper 15%, art paper 15%；(2) pulp from decoloured waste paper is using two sections of drifts
It is white, one section of hydrogen peroxide bleaching, hydrogen peroxide use 0.8-1.5%, bleaching levels 27%-30%, bleaching time 40-70 minutes；Two
Section methyl sulfinate bleaching, methyl sulfinate dosage 0.5%, 60-90 DEG C of bleaching temperature；
(3) the non-fluorescence whiteness of pulp from decoloured waste paper is 70-74%ISO；
(4) mixed slurry weight proportion are as follows: needlebush bleached sulphate chemical pulp NBKP is 15%-30%, and pulp from decoloured waste paper is
70%-85%；
(5) needlebush bleached sulphate chemical pulp, pulp from decoloured waste paper are manufactured paper with pulp after beating, in pulping process, are pressed in pulping process
Mixed slurry per ton adds 1.0-3.0kg sodium carboxymethylcellulose；Freedom is respectively that needlebush bleached sulphate chemical pulp is
275-325ml, pulp from decoloured waste paper 120-180ml；
(6) supplementary product consumption: cationic starch is 7-9kg/t paper；Amount of filler is 29-31%；AKD dosage is 20-30kg/t paper；
Retention agent PAM dosage is 0.4-0.8kg/t paper.
Further, supplementary product consumption: brightening agent dosage is 5-10kg/t paper, table glue brightening agent: 3-5kg/t paper in starching.
Further, blue dye 10-30g/t paper, xanthochromia 240-260g/t paper.
Further, surface sizing technique: top sizing amount presses 2-4g/m2, Cypres (enhanced): 2-4kg/t
Paper.
Further, surface sizing technique: rolling condition: line pressure 30-50kN/m, 90 DEG C of temperature.
Further, the high white ring of production protects highmulti paper characteristic: quantitative 53-118g/m2, whiteness 92-94%ISO is impermeable
Lightness is not less than 90%, water imbibition 20-30g/m2, longitudinal fracture length is not less than 3200m, and bulk is not less than 1.15cm3/ g, smoothly
Degree is not less than 30s, CIE whiteness 128-134%.
Beneficial effects of the present invention:
(1) present invention is solved and is produced in the prior art using pulp from decoloured waste paper using pulp from decoloured waste paper as main material production paper
Paper products whiteness it is low, printing color is low and deep, the bad technical problem of color reducibility, while having saved wood fiber raw material,
Reduce production cost.
(2) present invention produces Gao Bai equipped with a small amount of needlebush bleached sulphate chemical pulp using pulp from decoloured waste paper using main
Environment protection multifunctional paper, product whiteness is high, bulk is good, and color reducibility is good；What pulp from decoloured waste paper was produced by bleaching process
Although paper product whiteness is high, color reducibility is bad, and bleached sulphate chemical pulp reproducibility is strong, and and pulp from decoloured waste paper
Compatibility is preferable, and the whiteness of product is high after the two hybrid reaction, bulk is good, color reducibility is good, and bulk is good.
(3) present invention is furnished with a small amount of needlebush bleached sulphate chemical pulp, and and carboxylic using pulp from decoloured waste paper using main
Sodium carboxymethylcellulose pyce interaction, improves mobility and levelability, at the same make the high white ring produced protect highmulti paper have compared with
Good hand's sense and printability, meet people's esthetic requirement.
(4) present invention is more equipped with the high white ring guarantor of a small amount of needlebush bleached sulphate chemical pulp production using pulp from decoloured waste paper
Passing through the addition and interaction of auxiliary material, stiffness and high mechanical strength in functional paper, good stability of the dimension, polychrome chromatography is accurate,
Printed image is clear, and three-dimensional sense is strong, and printed matter is high-grade elegant, and picking speed is high, is applicable to high speed rotary printing.
(5) pulp from decoloured waste paper of the present invention is bleached using hydrogen peroxide and methyl sulfinate, and this technique can not only be abundant
The ink ion gone out in waste paper, obtains higher pulp brightness, moreover it is possible to so that pulping process is belonged to element chlorine free bleaching, produce
Journey, which does not generate, is difficult to biodegradable organohalogen compounds, realizes clean manufacturing.
