Abstract
The invention discloses a kind of sodium borohydride and the technique promoting sulfate pulping combined by hydrogen peroxide, belong to slurrying new technique, under conditions of sodium borohydride and hydrogen peroxide exist, plant material is processed；The present invention uses free of contamination pulping technique, and raw material dosage is few, to environmental condition without rigors, improves slurrying properties obvious, can obviously reduce pulp-making agent consumption.
Description
Technical field
The present invention relates to a kind of sodium borohydride and the technique promoting sulfate pulping combined by hydrogen peroxide, be an improvement
Pulping technique.
Background technology
In sulfate pulping process, add digesting assistant and can be effectively improved paper pulp yield, increase pulp strength, fall
Low steaming and decocting fluid volume, shortens digestion time, reduces production cost, thus is more and more paid attention to.Owing to using steaming and decocting to help
The advantage of agent is apparent from, and therefore, in digestion process, the method adding auxiliary agent obtains increasingly extensive application.Steaming and decocting helps
Agent principal item have anthraquinone (AQ) and dihydro dihydroxy-anthracene disodium salt (DDA) anthraquinone derivative, green oxygen, CT-1, polyacrylamide,
Compositional type auxiliary agent, surfactant etc..
In soda pulping process, due to the catalytic action of anthraquinone, accelerate the process of steaming and decocting delignification.This not only contributes to system
The raising of pulp yield, and alkali charge can be reduced, shorten digestion time, reduce boiling temperature and slurrying hardness.Green oxygen is maximum
Feature be for non-anthraquinone series compound, without carcinogen, do not cause environmental pollution, green oxygen steaming and decocting can reduce material consumption, contracting
Short digestion time, improves slurry intensity and pulp brightness.CT-1 digesting assistant mainly free by quinonoid compound and band active group
Epoxy forms.Quinonoid compound plays reduction-oxidation property in steaming and decocting, and free ring oxygen species can suppress cellulose
The speed of oxidation reaction, thus suppress the hydrolysis of cellulose, can also promote to terminate the acceleration of reaction simultaneously, suppression peeling is anti-
Should.
The application utilizes the reduction of sodium borohydride and oxidation two effect of hydrogen peroxide, promotes sulfate pulping, enters
One step improves pulping efficiency.
Summary of the invention
The technical problem to be solved is to provide the technique of the sulfate pulping of a kind of improvement, its Technology
Easily implement, pollution-free, improve the effective of slurrying, improve slurrying properties obvious.
The inventive method is under conditions of sodium borohydride and hydrogen peroxide exist, and plant material is carried out sulfate legal system
Slurry.
When processing plant material, sodium borohydride consumption is the 0.5-1.0% of raw materials quality, and hydrogen peroxide use is raw material
The 0.6-1.2% of quality.
When processing plant material, being also added into sodium hydroxide and sodium sulfide, total alkali charge is the 16-of raw materials quality
20%, sulphidity is 20-28%.
When processing plant material, temperature is 140-180 DEG C, and the time is 1.5-2.5h.
The invention has the beneficial effects as follows:
(1) consumption is few, and process implementing is easy；
(2) improve slurrying properties, use sodium borohydride and hydrogen peroxide to combine the technique promoting sulfate pulping, energy
Improve paper pulp yield and intensity 20-30%；
(3) use sodium borohydride and hydrogen peroxide to combine the technique promoting sulfate pulping, reagent consumption 25-30% can be reduced.
