Abstract
The present invention relates to a method for paper-making pulping. In the prior art, the method with characteristics of low cost, less pollution, mild conditions, and suitableness of large-scale operation does not exist in the existing paper-making pulping. With the present invention, the deficiency in the prior art is overcome, and the cost and the environmental pollution can be reduced. The method of the present invention comprises the following steps: (1) removing foreign bodies from straws, wood or weeds and other paper making raw materials, cleaning, and cutting into the pieces with the size of 1-2 cm; (2) adding clear water to the pieces at a temperature more than 0 DEG C to carry out slow imbibition, then rolling, and naturally freezing, wherein the natural freezing is the air temperature condition, for example, the winter climate condition of the region, wherein the air temperature can be reduced to less than -20 DEG C in the region; (3) carrying out thawing while stirring and grinding, wherein the thawing is the natural thawing or the artificial thawing.
Description
One, technical field:
The present invention relates to a kind of pulping and papermaking method, especially relate to a kind of pulping and papermaking method that utilizes winter, cold climate condition.
Two, background technology:
In the background technology, paper-making pulping lacks the method for suitable large-scale operation under a kind of cheapness, of low pollution, the temperate condition at present.Reason is not find a kind of method of destruction lignin, cellulose and hemicellulose cocrystallization of cheapness.
Soda acid is handled the difficult recovery of back residue soda acid, the polishing cost is high.Lignin is from solidification phenomenon is once more arranged, the easy and cellulose secondary combination of lignin after leaving high-temperature and high-pressure conditions.Bioanalysis is still immature so far.
Freeze-thaw technology is widely used in breaking-wall cell, does not need high temperature and organic solvent, has avoided lignin secondary and cellulosic combination again and self has condensed again, and is low to the acid-fast alkali-proof requirement of pre-processing device.But the energy consumption that realizes freezing required artificial cooling has increased cost again, has limited this technological heavy industrialization and has used.
The winter low temperature phase on ground such as China northeast, Inner Mongol is long, and is not enough always to freezing naturally industrial utilization.The a large amount of papermaking resource of the annual generation in these areas.
In the winter time, during the routine of forest and stalk class is stacked, because the wax layer on living beings surface stops rainwater to immerse, the freezing damaged surface that only appears at wood chip and stalk, deep layer place even the waste heat that also can releasing microbe ferments and bring.
Three, summary of the invention:
The present invention provides a kind of method with freeze thawing slurrying in order to solve the weak point in the above-mentioned background technology, and it can reduce cost and environmental pollution.
For realizing above-mentioned purpose, the technical scheme that the present invention adopts is:
A kind of method of paper-making pulping is characterized in that may further comprise the steps:
(1) living beings is removed foreign matter, clean, be cut into the 1-2cm shape;
(2) add clear water, freezing naturally, roll or stir;
(3) thaw:
(4) stir again, grind.
In the step (2), freezing naturally is temperature condition, for example can drop to the winter climate condition in the area below-20 ℃.
In the step (3), thaw for thaw naturally or manual work thaw.
Pulping raw material comprises stalk, timber or weeds.
Compared with prior art, the advantage and the effect that have of the present invention is following:
1, the present invention does not need high pressure, high temperature and artificial cooling.
2, the present invention does not produce black liquid.
3, the present invention can obtain the log quality.
4, the present invention is fit to large-scale production.
5, cost of the present invention is low, and is easy to use.
Four, the specific embodiment:
The present invention is the pretreated methods of a kind of living beings, and concrete technology is: in the winter time, can drop to the area below-20 ℃ at temperature, utilize nature freezing living beings such as stalk are carried out freezing on a large scale.Go up, thaw naturally at temperature and after manual work thaws, begin to carry out follow-up pulping process.With the wheat stalk is example: after removing foreign matters such as dust, metal, plastics, the cutting stalk becomes fragment and promotes the living beings suction.Put into low temperature resistant container, on a small quantity, repeatedly add clear water and constantly stirring, no longer absorb water until stalk.At the initial stage of nature between ice period, proceed appropriateness and stir.After arriving spring, freezing stalk begins to thaw, and perhaps manual work is melted.Stalk after thawing gets into the stage of slurrying subsequently.
The concrete technical scheme of the method for a kind of paper-making pulping of the present invention:
(1) paper making raw materials such as stalk, timber or weeds are removed foreign matter, clean, chopping becomes the 1-2cm size;
(2) under condition more than 0 ℃, add the slow imbibition of clear water, roll, freezing naturally; Naturally freezing is temperature condition, for example can drop to the winter climate condition in the area below-20 ℃.
(3) stir and grind while thawing, thaw for thaw naturally or manual work thaw.
Leachable can be used for cellulose, the production of hemicellulose alcohol fermentation after the freeze thawing treatment.
Principle of the present invention is: volume can increase behind isopyknic water freezing, the freezing back volume retraction that melts.Therefore can be used to destroy cell membrane.Straw after the suction, cauline leaf cell can imbibition occur because of the inclusions suction after suction; After freezing because of in the cell with the increase of the water freezing volume of periphery; Volume after the freezing thawing can dwindle once more; Thereby cause cell membrane and peripheral structure to be torn, the crystalline texture of the organic matter that lignin, cellulose and hemicellulose form is damaged.Lignin under the freezing conditions, cellulose and hemicellulose fragility increase.In all crystal structures, hydrone is to generally acknowledge the material that can get into crystal structure easily again, can not destroy the hydrophobic organic crystal structure very soon but hydrone gets into crystal.Only under the freeze thawing state, apply external force and can destroy the hydrophobic organic crystal structure.Naturally the suction of dry paper making raw material is very slow, but this process under natural low temperature need not expend cost.Suitable cutting and grinding have also promoted suction.
Under the contrast, pulping process such as soda acid, grinding are in order to reach quick suction, time saving purpose, the method for adopted warming and pressurizing, carrying out repeatedly.Freeze drying technology then be utilized for a long time, freeze thawing repeatedly gets rid of the big free water of moisture.It is common phenomenon that dry paper making raw materials such as stalk absorb water slowly naturally.
Still the cocrystallization that does not have at present ample evidence proof lignin, cellulose and hemicellulose formation has covalent bond to exist, and generally acknowledges between them with interaction of hydrogen bond.
Embodiment 1:
Wheat stalk is cut into the 1-2cm size, stirs, till stalk no longer absorbs water, cover the back and kept 12-100 hour, at room temperature melt naturally then, stir or grind with powerful simultaneously at low temperature below-20 ℃ while add clear water in the cement flooring.Get into the slurrying subsequent process afterwards.
Embodiment 2:
The wheat wood chip is cut into the 1-2cm shape, puts in the pond suction 12-100 hour, gets rid of to pull out behind the unnecessary water and shakeout in the cement flooring, the maintenance of low temperature below-20 ℃ 12-100 hour, during roll with Rolling Stone or road roller.Treat to stir or grind pulping after nature melts, get into pulping process thereafter again.
