Abstract
A hydrogen peroxide stabilizer composition in paper pulp bleaching contains the following materials by the weight percentages: ethylenediaminetetraacetic acid 8%-10%, polyacrylic acid 3%-5%, nitrilortiacetic acid 5%-10%, hydroxy ethylidene-1, 1-diphosphonic acid 5%-8%, sodium hydroxide in suitable amount and the rest of deionized water,. The preparation method includes: mixing the materials in the material ratio, adjusting the pH value to 6.8-7.1 with the sodium hydroxide and adding the deionized water to 100%. The inventive hydrogen peroxide stabilizer composition in the paper pulp bleaching can reduce the decomposition rate of the hydrogen peroxide to less than 20%, prevent the fouling from generating and dispersing pulp fibers and chelating metal ions.
Description
Technical field
The present invention relates to the stabiliser compositions of hydrogen peroxide in a kind of association with pulp bleaching.
Background technology
In the pulp bleaching process, compare, adopt that hydrogen peroxide bleaching has that adaptability is strong, retention of whiteness and bleached pulp brightness be than advantages such as height with the method for chlorine bleaches.Hydrogen peroxide can be eliminated carbonyl and the phenolic hydroxyl group on the part lignin macromolecule side chain in bleaching process; destroy or the minimizing chromophoric group; thereby improve pulp brightness effectively; and because the byproduct behind the hydrogen peroxide bleaching all is an oxide; chloride ion-containing not in the waste water; reduced toxicity and pollution, aspect environmental protection, had important practical significance.But during with hydrogen peroxide bleaching, heavy metal ion such as the iron that exists in the paper pulp, manganese can make the hydrogen peroxide accelerated decomposition, and the hydroperoxy-ion is reduced, thereby reduce bleaching effect.
Summary of the invention
Purpose of the present invention just provides and a kind ofly can suppress hydrogen peroxide decomposes, have simultaneously prevent that dirt from producing, the stabiliser compositions of hydrogen peroxide in the association with pulp bleaching of the effect of dispersing pulp fiber and chelated metal ions.
The stabiliser compositions of hydrogen peroxide is made up of following raw materials by weight percent in the association with pulp bleaching of the present invention:
Ethylenediamine tetra-acetic acid 8-10%, polyacrylic acid 3-5%, nitrilotriacetic acid 5-10%, 1-Hydroxy Ethylidene-1,1-Diphosphonic Acid 5-8%, an amount of, the deionized water surplus of NaOH.
The stabiliser compositions preparation method of hydrogen peroxide is in the association with pulp bleaching of the present invention: by proportioning ethylenediamine tetra-acetic acid, polyacrylic acid, nitrilotriacetic acid, 1-Hydroxy Ethylidene-1,1-Diphosphonic Acid are mixed, transfer pH value to 6.8-7.1 with NaOH, add deionized water again to very getting final product.
The stabiliser compositions using method of hydrogen peroxide is in the association with pulp bleaching of the present invention: directly add in the jar with bleaching liquid, spray woods or method such as in pipeline, mix and add, or directly join in the pulper, or join in slurry kneader or the heat dispersion machine, the consumption of stabiliser compositions is 1/10th of a hydrogen peroxide consumption.
In the association with pulp bleaching of the present invention in the stabiliser compositions of hydrogen peroxide, ethylenediamine tetra-acetic acid is mainly used in complexation of metal ions and separating metal, as water treatment agent and scale remover, can prevent the adverse effect that the metal ion that exists in the sealing causes for production and application link; Polyacrylic acid is nontoxic, and is soluble in water, the crystallite of salts such as calcium carbonate, calcium sulfate or silt can be scattered in the water not precipitate, thereby reach the scale inhibition purpose; Nitrilotriacetic acid is water insoluble, is dissolved in alkaline solution, has very strong complexing power, can form complex compound with multiple metal ion, is a kind of complexing agent commonly used; 1-Hydroxy Ethylidene-1,1-Diphosphonic Acid is a kind of organic phosphine acids anti-incrustation corrosion inhibitor, can form stable complex compound with multiple metal ions such as iron, copper, zinc.
The stabiliser compositions of hydrogen peroxide in the association with pulp bleaching of the present invention has the following advantages:
1, can reduce the hydrogen peroxide decomposes rate, make its resolution ratio less than 20%, when routine did not adopt stabilizing agent, the resolution ratio of hydrogen peroxide was greater than 40%;
2, can prevent that dirt from producing, and dispersing pulp fiber and chelated metal ions.
