Abstract
The invention relates to the technical field of papermaking, in particular to a papermaking method which particularly includes the steps: respectively roughly grinding peanut shells and cornstalks; mixing pulp; performing enzymolysis by pectinase, hemicellulose and ligninase complex enzyme; washing the pulp by a vibrating screen; fermenting and centrifugally separating the pulp; adjusting beating degree; mixing the pulp according to a conventional process and meeting the pulp requirement for making various paper products. According to the papermaking method, stewing can be avoided, carbon consumption is decreased, discharged wastewater does not contain harmful substances, the peanut shells and the cornstalks with short growth period replace wood pulp produced paper, cost can be reduced, and various performances of the prepared paper are excellent.
Description
Technical field
The present invention relates to a kind of pulp technology for making paper, particularly a kind of papermaking process.
Background technology
Current papermaking enterprise is restricted the bottleneck of development, mainly derives from following reason.One is resource scarcity, the developmental process of the timber of each cube needs the lengthy procedure of 10 ~ 15 years, two is that too much felling timber is for papermaking, be unfavorable for water and soil conservation, the Nature such as mud-rock flow, sandstorm disaster is of common occurrence, causes water and soil conservation imbalance to have close relationship with too much the cutting down forest of people.
Traditional paper-making process many uses highly basic strong acid boiling method, produces " three wastes " and discharges unavoidable contaminated environment, cause the attention of government and relevant department, so the row that the incomplete papermaking enterprise of environmental protection is just being shut down, stop, merge and change.But due to the progress of society, human civilization life all be unable to do without paper, the disparities between supply and demand of paper products are given prominence to, although the various measures such as paperless office are carried out energetically by government department, reduce the consumption of paper product as far as possible, but always can not accomplish with no paper life, so just there are the disparities between supply and demand of great disparity in paper products, demand constantly increases on one side, while just in pass, stop, and, turn, so market has openings constantly increases, many inconvenience is brought to the life of people, in order to alleviate these contradiction, the ramp of a kind of energy is found in the task of top priority, the new alternative papermaking raw material of contaminated environment can be avoided in process.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of papermaking process, and the method preparation technology is simply easy to control operation, and the straw plant that growth cycle can be utilized shorter substitutes wood pulp production paper, can reduce costs, protect forest vegetation, be conducive to environmental protection.
For achieving the above object, the present invention adopts following technical scheme:
A kind of papermaking process, comprises following preparation process:
(1) get 30 ~ 50 weight portion peanut shells, add its weight 8 ~ 12 times of water, adopt conventional kibbling mill that peanut shell is roughly ground into fibre stuff A;
(2) getting corn stem crosscut again becomes thickness to be the disk of 0.5 ~ 1cm, adds its weight 6 ~ 10 times of water, adopts conventional kibbling mill that peanut shell is roughly ground into fibre stuff B;
(3) mixed by fibre stuff A and fibre stuff B, add the complex enzyme of their weight 0.05 ~ 0.09%, regulate pH to 3.5 ~ 4.5, raised temperature to 35 ~ 45 DEG C, enzymolysis 5 ~ 8h, described complex enzyme is pectase, hemicellulase and lignoenzyme;
(4) cellulose paste step (3) obtained breaks pulp grinder through continuous hydraulic and breaks after slurry cleans, and flowing into aperture is that the vibrating screen of 1 ~ 3mm washs;
(5) by the cellulose paste bleaching after washing, with extruder cellulose paste is squeezed to and is moisturely divided into 45 ~ 48%, obtain cellulose paste dope;
(6) cellulose paste dope quality 0.1 ~ 0.4% yeast is added again at 28 ~ 32 DEG C of lower seal fermentation 8 ~ 13h;
(7) use centrifugal sereen centrifugation, regulate beating degree to be 37 ~ 40 ° of SR; Technique is sized mixing routinely, makes the slurry matter requirement of its various paper product that adapts to manufacture paper with pulp.
Described in the inventive method step (3), the mass ratio of pectase, hemicellulase and lignoenzyme is 5:2:1.If hemicellulose level is high in the slurry, paper pulp water retention value is large, can affect into paper character, and as become, paper opacity is low, tightness is large, fragility is large, and printability is poor.Water retention value is high, and the green deformation of paper is large, fallibility thick stick during chromaticity printing.The present invention adopts the complex enzyme of proper proportion, be able to by pectin enzymolysis, and after making washing, hemicellulose and lignin keep suitable amount, to improve paper quality.Wherein, lignoenzyme not only to lignin, and has very strong degradation capability to the pollutant that peanut shell and corn stem may exist.
Water in the inventive method step (1) and (2) is distilled water.Applicant's discovery distilled water is prepared slurry and is used for preparing paper, and paper quality is greatly improved, and storage life also extends 3 ~ 5 months.
The present invention by centrifugal sereen being not suitable with the thick slag of copy paper, the magazins' layout such as dust and cane marrow out.
The present invention prepares slurry by the method for enzymolysis and fermentation, can non-evaporatingly boil, and reduces the burning of carbon, has the effect of good energy-saving and emission-reduction, and the waste water of outer row is not also containing harmful chemical addition agent.Effectively can also control the amount of hemicellulose and lignin, applicant studies discovery, and hemicellulose and content of lignin control when 9 ~ 15% and 7 ~ 9% simultaneously respectively simultaneously, when controlling appropriate lignin, greatly improve the wet strength of paper, hemicellulose is polysaccharide, has hydroxyl, water imbibition is strong, fibre swelling when promoting to pull an oar, between fiber, bonding area increases, and is easy to making beating, substantially reduce the time of making beating and improve the engineering properties of paper, the size performance prepared and quality reach best.
Compared to existing technology, beneficial effect of the present invention is:
(1) papermaking process of the present invention is used; substantially increase the slurry yield of slurry; reach 90 ~ 95%, make full use of resource, simultaneously; the peanut shell that the present invention is used and corn stem utilize growth cycle shorter; substitute wood pulp production paper, can reduce costs, protect forest vegetation; be conducive to environmental protection, be also that peanut shell and corn stem are rised in value simultaneously.
(2) the present invention adopts enzymolysis and fermentation to combine, and avoid boiling, reduce the use of carbon, efflux wastewater does not contain hazardous substance, also non-exhaust emission, reaches the requirement of energy-conserving and environment-protective.
(3) by the size performance excellence that the inventive method prepares, the slurry matter requirement of various paper product of manufacturing paper with pulp is met.
