Description
Technical field
The present invention relates to a kind of technical field of digesting assistant of paper-making pulping, particularly relate to and be a kind ofly mainly used in the soda pulping process techniques such as timber soda processes, sulfate process and papermaking pulping cooking auxiliary that is efficient, environmental protection.
Background technology
Digesting assistant plays more and more important effect in pulping process, and China is based on grass as raw material, and exploitation is suitable for the digesting assistant of grass as raw material, slows down the pollution problem of grass as raw material pulping process, is one of direction developing digesting assistant at present.In addition, country in 2007 issues " papermaking Industry Development Policy " and clearly proposes to build forestry-paper base 5,000,000 hectares in 2010, newly-increased wood pulp production line 6,450,000 tons, the proposition of integrated timber-paper solves several difficult problems for China's paper industry: increase the long stapled supply of high-quality, improve wood pulp proportion, eliminate and fall behind straw pulp production line, optimize the structure of China's paper making raw material, solve the environmental problem that China's papermaking brings, forestry-paper integration project will become the developing direction of 21 century paper-making industry in this context, along with the proposition of integrated timber-paper, novel environment friendly, the digesting assistant being applicable to wood pulp production will become the research and development direction of digesting assistant.
Exploitation wood pulp production digesting assistant primary goal is then improve the selective of delignification in pulping process.The slurrying enterprise of current China nearly 2/4ths is at use akali sulphide, part uses green onion to wake up and derivative, but this kind of digesting assistant solubility property is poor, and it is slower to raw material infiltration, lignin degradation and dissolution time longer, the i.e. poor selectivity of delignification, this just causes the material removed and is easily adsorbed once again by fiber, affects quality and the yield of slurry.In addition, this analog assistant has certain toxicity, and environmental pollution is large, and in pipeline, easily fouling, large to equipment corrosion.
Summary of the invention
The object of the invention is the shortcoming in order to overcome above-mentioned prior art, a kind of digesting assistant of paper-making pulping is provided, the advantage such as the digesting assistant of this paper-making pulping has low toxicity, easy to prepare, stable performance, solubility property is excellent, penetrating power is strong.
The technical solution adopted for the present invention to solve the technical problems is: a kind of digesting assistant of paper-making pulping, be made up of the composition of raw materials component of following mass percent: 100-150 part 1-amino anthraquinones, 100-150 part 1, 4-dihydroxy anthraquinone, 300-350 part sodium hydrogensulfite, 300-350 part natrium nitrosum, 200-250 part calcium sulfite, 150-250 part sulfurous acid iron, 150-250 part sulfurous acid copper, 150-250 part sulfurous acid silicon, 150-250 part zinc sulfite, 150-250 part aluminium sulfite, 20-50 part sodium phosphate trimer, 20-50 part chelating agent, 20-50 part emulsifying agent, 50-60 part alkylaryl sulfonates, 50-60 part petroleum sulfonate, 50-60 part alkylbenzenesulfonate, 50-60 part alkyl ethyl sulfonate.
Further, described 1-amino anthraquinones is 100 parts, Isosorbide-5-Nitrae-dihydroxy anthraquinone is 100 parts, sodium hydrogensulfite is 300 parts, natrium nitrosum is 300 parts, calcium sulfite is 200 parts, sulfurous acid iron is 150 parts, sulfurous acid copper is 150 parts, sulfurous acid silicon is 150 parts, zinc sulfite is 150 parts, aluminium sulfite is 150 parts, sodium phosphate trimer is 20 parts, chelating agent is 20 parts, emulsifying agent is 20 parts, alkylaryl sulfonates is 50 parts, petroleum sulfonate is 50 parts, alkylbenzenesulfonate is 50 parts, alkyl ethyl sulfonate is 50 parts.
Or described 1-amino anthraquinones be 150 parts, Isosorbide-5-Nitrae-dihydroxy anthraquinone is 150 parts, sodium hydrogensulfite is 350 parts, natrium nitrosum is 350 parts, calcium sulfite is 250 parts, sulfurous acid iron is 250 parts, sulfurous acid copper is 250 parts, sulfurous acid silicon is 250 parts, zinc sulfite is 250 parts, aluminium sulfite is 250 parts, sodium phosphate trimer is 50 parts, chelating agent is 50 parts, emulsifying agent is 50 parts, alkylaryl sulfonates is 60 parts, petroleum sulfonate is 60 parts, alkylbenzenesulfonate is 60 parts, alkyl ethyl sulfonate is 60 parts.
In sum, the invention has the beneficial effects as follows: the digesting assistant of paper-making pulping of the present invention have retain fiber strong, improve pulp yield, reduce and steam angle composition, improve the washing of paper pulp and the consumption of bleachability, saving alkali and chlorine, reduce the aspects such as slurrying production cost and there is good effect and significant economic benefit.This auxiliary agent has good dispersiveness and permeability, can with blade Homogeneous phase mixing, and accelerate the infiltration of cooking liquor to raw material, thus greatly shorten digestion time (1 ~ 3 hour).This auxiliary agent can also accelerate lignin degradation, accelerates delignification speed, and the stripping of carbohydrate can be made also to become slow, effectively improve slurry yield, reduces alkaline consumption chlorine consumption, shortens bleaching time.This product can reduce black liquor viscosity, and make concentrated and wash faster, the whiteness of paper pulp significantly improves, and this auxiliary agent is also all improved the folding strength of paper, tear-resistant degree, brisement degree, bursting strength.
