Description
Technical field
The present invention relates to a kind of paper-making pulping digesting assistant, belong to field of papermaking.
Background technology
During chemical pulping, digesting assistant affect to a great extent the speed of delignification, the quality of pulping,
Paper pulp yield, and affect the effect of postorder bleaching.At present major part slurrying enterprise use akali sulphide, part use anthraquinone and
Derivative, but this kind of digesting assistant solubility property is poor, and relatively slow to raw material infiltration, lignin degradation and dissolution time are longer, and this is just
The material causing removing is easily adsorbed once again by fiber, affects quality and the yield of slurry.Additionally, this analog assistant has certain poison
Property, environmental pollution is big, easy fouling in pipeline, big to equipment corrosion.
Surfactant have washing, soak, permeate, disperse, emulsify, the effect of the aspect such as softness, froth breaking and function.It
The cooking liquor wetting to fibrous raw material can be promoted, accelerate boiling chemicals and the infiltration of other chemicals and uniformly diffusion, from
And promote cooking liquor to lignin in timber or non-timber and the removing of resin, moreover it is possible to play the effect of dispersion resin.Use cloudy from
Sub-surface activating agent and nonionic surfactant compounding, both can accelerate infiltration, promote lignin and the removing of resin, moreover it is possible to carry
High paper pulp yield, many-sided quality improving slurry, including reducing Kappa number and improving the intensity of slurry.
Summary of the invention
It is an object of the invention to provide a kind of paper-making pulping digesting assistant, safety non-pollution, it is possible to substantially shorten slurry
The digestion time of material, improves screened yield.
Described, paper-making pulping digesting assistant, consist of the following components in percentage by weight:
AEO 8-12%
Neopelex 10-20%
Alkyl sulfonamide sodium acetate 3-8%
APES 3-8%
NPE sodium sulfonate 2-5%
Dimethyl sulfonic acid 1-3%
Sodium carboxymethylcellulose 2-5%
Oleamide 0.5-1.2%
Sodium pyrophosphate 0.1-0.5%
Deionized water surplus
Preferably, paper-making pulping digesting assistant, consist of the following components in percentage by weight:
AEO 10%
Neopelex 15%
Alkyl sulfonamide sodium acetate 5%
APES 5%
NPE sodium sulfonate 3%
Dimethyl sulfonic acid 2%
Sodium carboxymethylcellulose 3%
Oleamide 1%
Sodium pyrophosphate 0.3%
Deionized water surplus
The preparation method of described paper-making pulping digesting assistant, comprises the following steps:
Deionized water is joined in reactor, be heated to 60-70 DEG C, by AEO, detergent alkylate
Sodium sulfonate, alkyl sulfonamide sodium acetate, APES, NPE sodium sulfonate put into reaction successively
Still, stirs 30-50 minute under the conditions of 60-70 DEG C, is then cooled to 40-50 DEG C, adds dimethyl sulfonic acid, carboxymethylcellulose calcium
Sodium, oleamide, sodium pyrophosphate, and stirring 20-30 minute, cooling discharging at this temperature.
Compared with prior art, the invention has the beneficial effects as follows:
The present invention uses anion and nonionic surfactant to compound, and has fabulous dispersiveness, improve in water
The permeability of raw material, improves the uniformity of boiling, promotes dispersion and the dissolution of lignin；Surfactant has good emulsification
Property and diffusivity, can prevent the colloid deviate from, lignin, resin etc. from being adsorbed once again by fiber after being distributed in black liquor uniformly；
Digesting assistant of the present invention reduces amount of caustic soda, shortens digestion time 30-50 minute, steam saving consumption, and screened yield improves
4-5%, Kappa number reduce 7-10, can part, replace akali sulphide, anthraquinone and derivative thereof the most completely, solve to a great extent
Determine waste water pollution problem；Slurry with digesting assistant boiling of the present invention is soft, loose, and pulping is uniform, and black liquor is prone to extract, starch
Little, good springiness is damaged in material drift.
