Abstract
The invention belongs to pulp technology for making paper, a kind of method being specifically related to cow dung paper pulp with cow dung as material, it is characterized in that comprising the following steps: (1) raw material cleaning treatment；(2) it is dehydrated；(3) decatize；(4) slurrying.This cow dung paper pulp is suitable for producing industrial wrapping paper or paper, it is not only paper grade pulp and provide a new resource, also the exploitation for animal husbandry discarded object cow dung create new purposes, solve the pollution to ecological environment for the cow dung, achieve the low input of refuse, usury use, reduces the cost of pulp product.
Description
Technical field
The present invention relates to a kind of method of cow dung paper pulp with cow dung as material.
Background technology
For manufacturing the paper pulp of wrapping paper or paper, mainly obtained after treatment by plant fiber material, different according to fibrous raw material, current paper making pulp has wood pulp, straw pulp, fiber crops paper pulp, bamboo pulp, cloth paper pulp and sugar slag paper pulp etc., make the paper pulp that raw material produces with cow dung, limited by traditional method for breeding, raise with the clustering of cattle-raising, the paper-making industry that is used in for cow dung provides condition, solve a large amount of cow dung can not process in time, the environmental pollution causing, also solves restriction and the puzzlement of Papermaking Resource.
Content of the invention
The purpose of the present invention, is to provide a kind of method of cow dung paper pulp with cow dung as material, the method: comprise the following steps
(1) raw material cleaning treatment: cow dung is poured in foam material pond and clean, be soaked in water under room temperature, stirring, make dirt sand precipitate, fibre object is leached entrance scummer slagging-off；
(2) it is dehydrated: raw material dehydration process after removing the gred, water content 15-30%；
(3) decatize: after dehydration, raw material enters decatize storehouse, adds 5-7%NaOH, temperature 85-95 DEG C, time 40min；
(4) slurrying: after decatize, raw material enters pulper slurrying, input concentration 25-30%, beating degree 2OSR, obtains cow dung paper pulp.
The present invention not only paper grade pulp provides a new resource, also new purposes has been started in the exploitation for animal husbandry discarded object cow dung, the invention of cow dung paper pulp, solves the pollution to ecological environment for the cow dung, it is achieved that the cost of pulp product is used, reduced to the low input of refuse, usury.
Detailed description of the invention:
Below in conjunction with embodiment, the present invention is further described, and this fact Example is embodiment when carrying out handsheet quality testing for the cow dung paper pulp, and the production stage of its cow dung paper pulp is:
(1) raw material cleaning treatment: pour 20KG cow dung in container into, is soaked by room temperature water, and limit immersion limit is stirred, and makes fibre material float, and dirt sand sinks to the bottom, and then pulls fibre material out, prevents removing the gred three times in scummer；
(2) it is dehydrated: raw material dewaterer after slagging-off is sloughed moisture, water content 25%；
(3) decatize: after dehydration, steam box put into by raw material, the NaOH adding 6%, steam temperature controls at 85-95 DEG C, steams 40min；
(4) slurrying: after decatize, raw material entrance SLG twin-screw Multifunctional pulper carries out material extrusion slurrying, input concentration 25-30%, beating degree 2OSR (2g) after squeezing, and obtains product cow dung paper pulp.Enter above-mentioned gained cow dung paper pulp in 75 DEG C of hot-tubs and carry out disappearing latent, make torsional deformation fiber in paper pulp obtain combing, time 10min, rear enter 23L beater, process is (7KG/10min) 33SR (1.5g)；Then cow dung paper pulp APSP laboratory handsheet machine is copied to obtain the scraps of paper of Ф 200mm, detect it through physical property quantitative: 149g/m2；Fracture length: 2054m；Ring crush index；11.28Nm/g.Through experimental analysis, after it by bubbling open comb solution to raw material, calculate roughly to obtain actual available county fiber about 55%.Detection proves, the cow dung paper pulp that the present invention produces, and is completely suitable for the conventional copy paper of industry, is i.e. applicable on paper machine manufacture " machine-made paper ".
Claims (1)
1. one kind by the method for cow dung paper pulp with cow dung as material, it is characterised in that comprise the following steps；(1) raw material cleaning treatment: cow dung is poured in foam material pond and clean, be soaked in water under room temperature, stirring, make dirt sand precipitate, fibre object is leached entrance scummer slagging-off；(2) it is dehydrated: raw material dehydration process after removing the gred, water content 15-30%；(3) decatize: after dehydration, raw material enters decatize storehouse, adds 5-7%NaOH, temperature 85-95 DEG C, time 40min；(4) slurrying: after decatize, raw material enters pulper slurrying, input concentration 25-30%, beating degree 20SR, obtains cow dung paper pulp.
