Abstract
The present invention belongs to the field of papermaking technology, and is especially cow dung paper pulp produced with cow dung as material. The cow dung paper pulp is produced through the steps of washing material, dewatering, steaming and pulping. The cow dung paper pulp is suitable for producing industrial packing paper or common paper. The present invention provides new pulp source, and has waste utilization, environment friendship and low cost.
Description
Technical field:
The invention belongs to pulp technology for making paper, be specifically related to a kind ofly make the cow dung paper pulp of raw material production with cow dung, this cow dung paper pulp is fit to manufacture with wrapping paper or paper.
Background technology:
Be used to make the paper pulp of wrapping paper or paper, mainly obtain after treatment by plant fiber material, according to the fibrous raw material difference, paper making pulp has wood pulp at present, straw pulp, fiber crops paper pulp, bamboo pulp, cloth paper pulp and bagasse pulp etc., still do not see the paper pulp of making raw material with cow dung, and traditional method for breeding is restricted the collection of cow dung and utilization, generally be used for field fertilization or make fuel, follow the clustered of cattle-raising to raise, the a large amount of cow dungs such as the untimely processing that produce, to cause environmental pollution, become the root of disease or infectiousness pandemic, the threat people's is healthy, and current just call " curing separation; anaerobic fermentation is produced biogas ", its implementation cost height of processing to a large amount of cow dungs.Above-mentioned in addition several paper pulp of talking about all exist resource limit and puzzlement.
Summary of the invention:
Purpose of the present invention provides and a kind ofly makes the cow dung paper pulp of raw material production with cow dung, and it is achieved in that
(1) raw material clean: pour cow dung into bubble and expect to clean in the pond, with the water enchroachment (invasion) bubble, stir under the room temperature, make dirt sand precipitation, fibre object is leached enter the scummer slagging-off;
(2) dehydration: the back raw material processed that will remove the gred, moisture 15-30%;
(3) decatize: the storehouse is steamed in the raw material admission of dehydration back, adds 5-7%NaOH, 85 ℃-95 ℃ of temperature, time 40min;
(4) slurrying: raw material enters pulper slurrying after the decatize, gets cow dung paper pulp.
NaOH is to the pollution of water environment in the lignin liquor in order to reduce, and the steaming step that this method is included can adopt the raw material admission of dehydration back to steam the storehouse, adds the 0.1-0.05% anhydrous industrial alcohol, 85 ℃-95 ℃ of temperature, time 40-50min.Also can not add any chemicals, 90 ℃ of-100 ℃ of time 40-50min of temperature.
The present invention not only provides a new resource for paper grade pulp, also started new purposes for animal husbandry discarded object cow dung, the invention of cow dung paper pulp has solved the pollution of cow dung to ecological environment, realize low input, the usury usefulness of refuse, reduced the cost of pulp product.
The specific embodiment:
Give below and close embodiment the present invention is further described, this embodiment is the experimental example of cow dung paper pulp when copying the sheet quality testing, and the production stage of its cow dung paper pulp is:
(1) raw material clean: 20Kg cow dung is poured in the container, soak with room temperature water, stir while soaking, make the fibre material come-up, dirt sand sinks to the bottom, and then fibre material is pulled out, puts into scummer slagging-off three times;
(2) dehydration: slagging-off back raw material is sloughed moisture content with Water Extraction Machinery, and moisture is 25%;
(3) decatize: dehydration back raw material is put into steam box, adds 6% NaOH, and vapor (steam) temperature is controlled at 85 ℃-95 ℃, steams 40min;
(4) slurrying; Raw material enters the multi-functional pulper of SLG twin-screw and carries out material extrusion slurrying after the decatize, input concentration 25-30%, squeeze back 20 ° of SR of beating degree (2g) product cow dung paper pulp.
Above-mentioned gained cow dung paper pulp entered in 75 ℃ of hot-tubs to soak disappear latently, the torsional deformation fiber is unclogged and readjusted, time 10min, after enter the 23L beater, process is (7Kg/10min) 33 ° of SR (1.5g); Then with cow dung paper pulp with the APSP laboratory copy the sheet machine copy the scraps of paper of Φ 200mm, detect through physical property that it is quantitative: 149g/m
2Fracture length: 2054m; Ring crush index: 11.28Nm/g.Through experimental analysis, its by former parison is opened discongest after, calculate roughly the actual fiber about 55% that utilizes.Detect proof, the cow dung paper pulp that the present invention produces is applicable to that fully industrial routine copies paper, promptly is applicable to and makes " machine-made paper " on the paper machine.
Claims (3)
