Description
Technical field
The invention belongs to paper for daily use technical fields, and in particular to a kind of producer of the household paper pulp of environmental protection and energy saving
Method.
Background technology
With the development of China's paper for daily use industry, domestic enterprise mostly using Cotton Pulp as the raw materials for production of paper for daily use,
But restricted by cultivated area and growth cycle, the raw material is increasingly short, has seriously affected China's paper for daily use industry
Development.There is only a few enterprise to attempt the raw materials for production using bamboo pulp as paper for daily use therefore, and have been achieved with initial success,
Such as Patent No. CN02112175.3, the patent of invention of entitled " bamboo pulp denatured productive technology " discloses a kind of bamboo pulp
Production technology, but bamboo fibre average length is less than papermaking wood-fibred, and because its ash is more, pentose content is high, and bamboo fiber
Matter is hard, heavy wall, lumen is narrow, fibr tissue is fine and close, there are cause production difficulty the problems such as air, it is necessary to raw material in cell
It is more, it is of high cost, thus also fail to be widely applied.To reduce production cost, steady production operation, research and development meet paper for daily use life
The dissolving pulp substitute products of production requirement have become a top priority.
The content of the invention
The purpose of the present invention is being directed to the problem of existing, a kind of producer of the household paper pulp of environmental protection and energy saving is provided
Method.
The present invention is achieved by the following technical solutions：
A kind of production method of the household paper pulp of environmental protection and energy saving, comprises the following steps：
（1）Stock：Bamboo pulp is scattered through alkali spray and discongesting for blender, it is then re-fed into squeezer and carries out extrusion dehydration,
Obtain slurry；
（2）Boiling：By step（1）Obtained slurry carries out boiling using kraft cooking technique；Wherein, amount of caustic soda accounts for absolutely
The 10-12% of dry pulp, sulphidity 20%, bath raio 1：5, boiling temperature be 100 DEG C of early period, 110 DEG C of later stage, early period digestion time
For 50-60min, later stage digestion time is 45-50min, and the Kappa number of slurry is 35-65 after boiling；
（3）Grinding：To step（2）The zinc flake of its quality 5-8% is added in slurry after middle boiling, then at 60-80 DEG C
Be ground 3-5 it is small when；
（4）Chlorination：By step（3）Slurry after middle milled processed carries out chlorination, adds in hydrochloric acid, liquid chlorine, caustic soda, before ensureing chlorination
Containing chloride for 12-18g/m containing alkali after 0.08-0.12g/L, chlorination after sour 0.04-0.06g/L, chlorination3；
（5）Vacuum impregnation is handled：By chlorination, treated that slurry is added in vacuum reaction kettle carries out processing 15-20min；
（6）Acid treatment：Citric acid is added in vacuum impregnation treated slurry and carries out acid treatment 15-20min, through spray into drift
Pond is 0.3g/L containing acid, manufactures paper with pulp through paper machine, is packaged as fixed weight 550g/m2Bamboo pulp.
Further, the step（1）The slurry concentration of middle slurry is 10%.
Further, the step（2）Mid-early stage boiling and later stage boiling intermediate period are 3-5min, boiling early period
With being placed naturally in the later stage boiling midfeather time.
Further, the step（3）Middle zinc flake granularity is 800 mesh.
Further, the step（3）Middle zinc flake preparation method is：Its quality is added in 350 mesh spherical zinc powders
The silica flour of 3.5% pentaerythrite and its quality 0.02%, uniformly after mixing, when progress ball milling 2 is small, ball material mass ratio is 100:1,
Then sieved, obtain 800 mesh zinc flakes to get.
Further, the step（6）Acid treatment：Add in citric acid, citric acid drop rate be 0.35mL/min, acid at
Manage time 18min.
The present invention has the following advantages compared with prior art：After the present invention to slurry by carrying out boiling, the bamboo in slurry
Fiber is in soft state, then carries out defibrination, and a certain amount of zinc flake is added in defibrination, can effectively improve defibrination
Efficiency can significantly reduce ash in bamboo fibre, pentose content, improve the purity of slurry, meanwhile, it is only by zinc flake
Special physical arrangement, when carrying out defibrination in the slurry, can fully contact with each other friction with the bamboo fiber in slurry, in defibrination
During, bamboo fiber hardness and heavy wall can be effectively reduced, crushes bamboo fiber tissue, release bamboo fiber is intracellular
Tolerant matter so as to effectively improve the quality of slurry, improves into the performance of paper, and paper is tear-resistant after being especially formed into paper
Performance is greatly enhanced, slurry primary quality measure produced by the present invention：Dynamic viscosity 10-14mpa.s；First kind fiber
Element >=95%；Ash≤0.02%；Irony≤10ppm；Whiteness >=90%；Moisture≤10%；Reactivity worth≤200s；The degree of polymerization
400-600, slurry produced by the present invention meet the production requirement of paper for daily use.The production method of the present invention is simple for process, operation
Convenient, the slurry of production meets the production requirement of paper for daily use, energy conservation and environmental protection, and the paper for daily use strength character of preparation is more preferable.
