Abstract
The invention relates to a process for dyeing a dark green industrial paperboard, which comprises the following steps: firstly, adding water into a paper pulp raw material until the paper pulp raw material is disintegrated by a hydrabrusher; dehydrating the disintegrated paper pulp with a decker and conveying the product into a primary pulp pool for uniform stirring and mixing with a sizing agent; feeding the mixture into a pulping machine with a stock pump for pulping; and introducing the pulped mixture into a machine chest for the use of a paper machine in the next procedure. The formula of a dye in the process comprises that: a, the paper pulp raw material is wood fiber; b, the using amount of the dye is 0.007+/-0.00032 percent, wherein direct turquoise is 0.00630+/-0.00030 percent and auramine is 0.00070+/-0.00002 percent; and c, a fixing agent made from 0.2+/0.003 percent of aluminum sulphate. The product produced by the process is uniform in color and fadeless for long time.
Description
Technical field
The present invention relates to the dyeing in a kind of industrial cardboard production process, belong to the dyeing technical field that coloured paper is produced.
Background technology
Existing bottle green industry insulating board production process mostly is pulping and adds dyestuff later on, and the light yellow and color-fixing agent aluminum sulfate of alkali-free in the dye formulation, and the cardboard color homogeneity of manufacturing paper with pulp out like this is poor, and surface oxidation-resistant is poor, with the passing of time fugitive color.And the client requires relatively strictness to the cardboard color, and stable for guaranteeing product color, colour-fast nondiscolouring must be chosen dyestuff, reserve prescription, formulates optimised process.
Summary of the invention
The objective of the invention is to select chemical staining reagent for use at the wood pulp plant cellulose, find out rational Recipe, the particularly adding of dyestuff alkaline bright yellow and color-fixing agent aluminum sulfate, and coloring agent added in the paper pulp before the slurry process, by with the mixing of slurry, grinding, fixation, produce the cardboard that meets customer demand.
The object of the present invention is achieved like this: the dyeing of dark green industrial paperboard: after (1) adds water to the hydrabrusher size degradation with raw material paper pulp earlier, dewater to former stock tank through decker, the dyestuff that has mixed up is added former stock tank, mix with slurry, send into paste mill grinding with stock pump again, the slurry that mill is good enters machine chest, for the paper machine use of next procedure.
(2) dye formulation:
A, paper pulp raw material: wood pulp cellulose
B, dye dosage: 7 ± 0.32 ‰
Wherein: directly bright blue: 6.30 ± 0.30 ‰
Alkaline bright yellow: 0.70 ± 0.02 ‰
C, color-fixing agent: aluminum sulfate 20 ± 3 ‰
The cardboard color even that the present invention produces, colour-fast for a long time under high temperature and sunlight; This dye technology retention height, permeability is strong, and the waste water of discharge is limpid, can handle with paper waste, realizes qualified discharge; Dye dosage is few, and is simple to operate.
Description of drawings
Fig. 1 is a process chart of the present invention.
The specific embodiment
Its products' realization process is: as shown in Figure 1, after earlier raw material paper pulp being added water to the hydrabrusher size degradation, dewater to former stock tank through decker, the dyestuff that has mixed up is added former stock tank, stir a period of time, mix with slurry, send into three tandem double disc refiner defibrinations with stock pump again, the slurry that mill is good enters machine chest, for the paper machine use of next procedure.
The composition of raw materials of this technology is (gross weight 1000kg):
A, raw material: get 730kg100% true qualities wood pulp cellulose.
B, dye dosage: 7 ± 0.32 ‰.
Wherein: directly bright blue: embodiment 1 gets 60kg, and example 2 is got 66kg;
Alkaline bright yellow: embodiment 1 gets 6.8kg, and example 2 is got 7.2kg;
The surplus that c, color-fixing agent: aluminum sulfate: embodiment 1, example 2 are got total amount 1000kg respectively.
Claims (1)
1. the dyeing of a dark green industrial paperboard is characterized in that:
(1) after elder generation adds water to the hydrabrusher size degradation with raw material paper pulp, to former stock tank, the dyestuff that has mixed up is added former stock tank through the decker dehydration, mix with slurry, send into paste mill grinding with stock pump again, the slurry that mill is good enters machine chest, for the paper machine use of next procedure;
(2) dye formulation:
A, paper pulp raw material: wood pulp cellulose
B, dye dosage: 7 ± 0.32 ‰
Wherein: directly bright blue: 6.30 ± 0.30 ‰
Alkaline bright yellow: 0.70 ± 0.02 ‰
C, color-fixing agent: aluminum sulfate 20 ± 3 ‰
