Abstract
The invention provides a method for making pulp using feather as raw material, belonging to the manufacturing engineering of paper making or pulp for paper products. The invention applies softening, hydrolyzing, grinding up, jordaning and filter-pressing to make pulp. The whole process doesn't pollute environment and the discharged waste water can be recycled after filtration. The paper and paper products produced by feather can be reused and degradated to fertilizer. The obtained paper pulp can manufacture different papers or other paper products such as dining box by present manufacturing engineering and equipments of paper making or other paper products.
Description
Technical field
The present invention relates to make the method for paper pulp, particularly a kind ofly make the method that raw material is made paper pulp, belong to and make paper or paper products manufacturing technique with slurry with feather.
Background technology
Traditional paper technology since bimillennium is to be main raw material with string such as timber, reed, bamboo etc. always, consumes a large amount of high-quality timber, the broken ecological balance, serious environment pollution encircled.And the discarded object feather (feather that refers to birds such as chicken feather, drake feather, goose feather) of a large amount of existence is not obtained utilizing.
Summary of the invention
The purpose of this invention is to provide a kind of method of making raw material manufacturing paper pulp with feather.
Realization the object of the invention is made the method that raw material is made paper pulp with feather, comprises the steps:
(1) clean: after with clear water foreign material such as the blood of adhering on the feather, ight soil, sandy soil being cleaned up, filtering moisture content;
(2) press dry: the moisture content that adsorbs on the feather is pressed dry, press off the thick stalk in the feather simultaneously;
(3) softening: add the strong base solution of the 0.4-1.0% that did not have feather, soaked at ambient temperature 48-96 hour, make the feather deliquescing after, again feather is pressed dry and reclaims alkali lye;
(4) hydrolysis: the feather after will pressing dry, add the aqueous solution of protease of the 0.5-1.5 ‰ no feather, soak at ambient temperature that coarse filtration goes out feather after 20-30 hour, and the recovery aqueous solution of protease;
(5) fine ground: that feather after the hydrolysis and feather stem are rolled into filament;
(6) defibrination: the feather filament after will rolling send paste mill grinding, and slurries filter through pulp screen, gets screenings, and oversize returns fiberizer and repeats the defibrination filtration;
(7) filter: (6) gained screenings is filtered through 80-100 order filter, and reclaim filtrate;
(8) slurrying: will filter back gained pulpboard and send pulper slurrying to get paper pulp.
To gained screenings behind the variegated feather defibrination, use 3-6%H
2O
2Solution soaks decolouring to white back and filters under 50-90 ℃ of condition.
Highly basic among the present invention can be selected NaOH, KOH etc. for use.Protease can be selected pepsin, trypsase, alkali protease etc. for use.According to the difference of making paper or paper products, add reinforcing agent, brightening agent etc. by existing process choice.Reinforcing agent is selected polyvinyl alcohol for use, and addition is the 10-25% of feather weight, also can select carboxymethyl cellulose for use, and addition is the 2-8% of feather weight, but also both select for use simultaneously; Brightening agent can be selected titanium dioxide or fluorescent bleaches for use, and addition requires to be no more than the heavy 1-7% of paper according to whiteness.
Gained paper pulp of the present invention adopts the existing technology of making paper or other paper products and the equipment various paper of can manufacturing paper with pulp out, or makes other paper products such as cutlery box, has wide range of applications.
The equal platymiscium fiber of tradition paper making raw material, its long-chain attract each other by intermolecular hydrogen bond and reticulate structure, and therefore the paper of making has certain intensity.Feather is purer protein, belong to scleroprotein, be natural polymer also as string, but molecular memory is in the space multistory structure, interchain forms stereochemical structure by hydrogen bond, fat key, sat linkage, disulfide bond and other power in the molecule, be not easy to form the attached keys that help such as hydrogen bond like this between the protein molecule, the reason of paper is made the scleroprotein of this class of feather in nobody's consideration for a long time just.The present invention overcomes above-mentioned prejudice, through repetition test, its objective is the attached key that helps that destroys feather class scleroprotein, and do not destroy major key (peptide bond), just destroy scleroprotein two, three, quaternary structure, keep primary structure, make feather class scleroprotein become the linear macromolecule structure, protein becomes linear macromolecule as string like this, simultaneously the peptide bond in the protein molecule and other polar functional group also can help strongly in that intermolecular formation hydrogen bond etc. is attached, so just can make the scleroprotein of feather one class equally be used for papermaking with string.
The present invention has started a kind of new raw material of making paper or paper products, and this abundant raw material exists a large amount of waste feathers at present, and comprehensive utilization of waste materials is turned waste into wealth in the present invention, almost all is converted into paper pulp.Free from environmental pollution in whole process of production, only discharging contains the waste water of foreign material such as blood, ight soil, sandy soil, can reuse after the filtration.Paper and the paper products made as raw material with feather, with processing and utilization again later, and with after can be degraded to fertilizer at nature, secondary contaminated environment not.
In sum, the present invention have abundant raw material, technology simple, need not that complicated special equipment, cost are low, comprehensive utilization, advantage such as free from environmental pollution, have great promotional value, will produce than great society benefit and economic benefit after the enforcement.

Claims (4)
1, a kind ofly makes the method that raw material is made paper pulp, it is characterized in that comprising the steps: with feather
(1) clean: after with clear water foreign material such as the blood of adhering on the feather, ight soil, sandy soil being cleaned up, filtering moisture content;
(2) press dry: the moisture content that adsorbs on the feather is pressed dry, press off the thick stalk in the feather simultaneously;
(3) softening: add the strong base solution of the 0.4-1.0% that did not have feather, soaked at ambient temperature 48-96 hour, make the feather deliquescing after, again feather is pressed dry and reclaims alkali lye;
(4) hydrolysis: the feather after will pressing dry, add the aqueous solution of protease of the 0.5-1.5 ‰ no feather, soak at ambient temperature that coarse filtration goes out feather after 20-30 hour, and the recovery aqueous solution of protease;
(5) fine ground: that feather after the hydrolysis and feather stem are rolled into filament;
(6) defibrination: the feather filament after will rolling send paste mill grinding, and slurries filter through pulp screen, gets screenings, and oversize returns fiberizer and repeats the defibrination filtration;
(7) filter: (6) gained screenings is filtered through 80-100 order filter, and reclaim filtrate;
(8) slurrying: will filter back gained pulpboard and send pulper slurrying to get paper pulp.
2, make the method that raw material is made paper pulp according to claim 1 is described with feather, it is characterized in that gained screenings behind the variegated feather defibrination, use 3-6%H
2O
2Solution soaks decolouring to white back and filters under 50-90 ℃ of condition.
3, make the method that raw material is made paper pulp according to claim 1 is described with feather, it is characterized in that highly basic can select NaOH, KOH for use.
