Abstract
The invention belongs to a paper technology, and relates to a making method of color card paper. The method comprises the steps that basic materials, namely bleached softwood kraft pulp and bleached hardwood kraft pulp, are sequentially subjected to processes of beating, pulp compounding, starching, paper making, pre-drying, surface sizing, after-drying, press polishing, and rewinding to be made into finished paper; a dye and an auxiliary raw material are added in a process flow; according to a transfer sequence of the materials, the materials sequentially pass through a pulper, a front knocking pulp chest, a pulping machine and a rear knocking pulp chest in the beating process; the materials sequentially pass through a pulp compounding chest, a transit pulp chest, a paper machine pulp chest and a top box in the pulp compounding process; the materials sequentially pass through a first pulp pump, a slag separator, a second pulp pump and a pressure screen in the starching process; the materials sequentially pass through a head box, a met part and a press part in the paper making process; 60-70% of the total amount of the dye is added in a material compounding chest; 10-20% of the total amount of the dye is added in a position of the surface sizing; and the balance of the total amount of the dye is added at the top box. The making method can automatically control colors of the paper, and is low in cost, and a hue of a product is stable.
Description
Technical field
The invention belongs to paper technology, relate to a kind of production method of colored paperboard.
Background technology
Along with expanding economy, the market demand of chromatics paper is increasing, and it is more and more higher that the outward appearance form and aspect require, but high-grade ticker tape or take import as main, price is higher.
The outer dyeing of internal dying and slurry is arranged on the colouring method, the outer dyeing of slurry (the outer dip dyeing of top sizing dyeing or machine) has that dyestuff retention on paper is high, production operation is simple, change paper convenient, do not need to clean stock tank, the advantage such as the water consumption is low and environmental pollution is little.But be prone to uneven dyeing and middle and surface color inconsistence problems, affect attractive in appearance and result of use, become paper of low grade, price is also low.
Domestic production producer adopts batch dyeing method in the solid dye slurry mostly at present, adds dyestuff in beater or dosing chamber, the method even dyeing, and it is high to produce the paper class.But also have following problem: 1, the form and aspect governing speed is slow, and the dying operation process is complicated, can't satisfy the requirement of high speed paper machine; 2, the paper look easily changes with various fluctuations, causes form and aspect control difficulty, and batch form and aspect are unstable; 3, can't carry out different tones and produce continuously, will clean during the change kind, consume large; 4, a large amount of reuse plain boiled water, having polluted environment also increases cost.
Summary of the invention
Technical problem to be solved by this invention is, provide a kind of can automation control paper look, the production method of the product form and aspect are stable, cost is low colored paperboard.
The production method of colored paperboard of the present invention is: with base stock bleached sulphate softwood pulp and BRATSK successively through making beating, with slurry, starching, manufacture paper with pulp, front drying, top sizing, after dry, press polish make into paper with the rewinding operation, in process flow, add dyestuff and auxiliary material; Transfer sequence according to material, described pulping process material successively through pulper, kowtow front stock tank, fiberizer and kowtow after stock tank, described with slurry operation material passes through with slurry pond, transfer stock tank, paper machine stock tank and header box successively, and described upper slurry process material is successively through 1
#Fan pump, scummer, 2
#Fan pump and pressurized screen, the described operation material of manufacturing paper with pulp passes through flow box, wet end and press section successively; The 60-70% of the total consumption of described dyestuff adds at dosing chamber, and the 10-20% of the total consumption of dyestuff adds at the top sizing place, and is remaining in the header box interpolation, is used for accurate form and aspect control.The interpolation total amount of dyestuff is determined according to shade and kind of dyes.The method is by the datumization control to color, use toning software according to the data of three primary color theory and survey, dyestuff or the stoste good dilution are transported to continuously toning in the header box with accurate measuring pump accurate measurement, realize the automated production of colored paperboard, can adjust quickly and easily required color, simplify production operation, make things convenient for quality control, the toning precision is high, becomes the paper form and aspect stable.
Between described press polish operation and the curling operation color detection means is set, the detection signal of color detection means exports the automatic color regulating system to, and the control instruction control measuring pump of automatic color regulating system output is regulated the dyestuff that the header box place adds.
In the described with slurry operation, the mass ratio of the bleached sulphate softwood pulp in the base stock is 10%-15%, and the mass ratio of BRATSK is 85%-90%, and the pulpboard whiteness is all greater than 85%; The cationic starch that adds conventional amount used in the with slurry pond.
Add the AKD of conventional amount used in the described header box; Described 1# fan pump porch adds calcium carbonate, and consumption is the 18-22% of oven dry stock quality, because dyestuff is filled after adding dyestuff easily with the filler loss, can allow dyestuff and fiber have enough contacting to dye the time; Described 2# fan pump porch adds color-fixing agent, and color-fixing agent consumption light color is the 0.1-0.2% of oven dry stock quality, and dark color is the 0.3-0.4% of oven dry stock quality, add color-fixing agent after adding dyestuff in the slurry, can improve the reservation of dyestuff, improve the COLOR FASTNESS of paper, improve the poor problem in two sides; The preservative that before pressurized screen, adds conventional amount used.
The present invention combines batch dyeing in top sizing dyeing and the slurry, divides 3 addings with dyestuff at dosing chamber, header box and top sizing, adopts modernized automatic color regulating system successfully to produce desirable colored paperboard, and its advantage applies exists:
(1) dyestuff divides 3 addings, can significantly reduce the DYE PRODUCTION cost, satisfies the requirement to form and aspect, is beneficial to accurate control, the automated production of coloured paper.
(2) this automation tinting system toning flexibly and fast can access various required form and aspect at short notice, and production control is convenient, and paper forming rate is high; Different form and aspect can be manufactured paper with pulp continuously, and the plain boiled water utilization rate is high, and is little to the pollution of environment, and comprehensive production cost is low; Can adapt to various fluctuations, the toning precision is high, becomes the paper form and aspect stable, consistent.
The colored paperboard of (3) producing with the method is bright in luster, color and luster is even, positive and negative aberration is little, COLOR FASTNESS good.
