Abstract
The invention discloses a method for making sulfate natural color paper pulp from ageratina adenophora. The method comprises the following steps: step one, firstly drying full ageratina adenophora straw, removing leaves, and chopping the straw into material slices; step two, adding a medicine solution blended by NaOH, Na2S and water to be pretreated for 10-90min; step three, adding the pretreated raw material and the material solution in an electric-heating pressure digesting pan to be digested, warming to 80-190 DEG C from the room temperature for 40-120min, and preserving temperature for 30-120min at the highest temperature; step four, digesting to obtain coarse pulp, separating the pulp from digesting waste liquid through a filter net, washing by using cleaning hot water at 60-90 DEG C; step five, pulp-screening the cleaned pulp by using a panel vibration screen, dehydrating the screened pulp to obtain the ageratina adenophora sulfate natural color pulp. The method disclosed by the invention is short in digesting time, industrial in production, and capable of effectively solving the defect that the existing ageratina adenophora cannot be used for producing the paper pulp in large scale.
Description
Technical field
The invention belongs to pulp and paper technology field, particularly relate to a kind of method of Eupatorium adenophorum bar extracting sulfuric acid salt true qualities paper pulp.
Background technology
Eupatorium adenophorum (Eupatorium adenophorumSpreng) is a kind of typical exotic invasive thing, is mainly distributed in the areas such as Yunnan, Guizhou, Sichuan, Chongqing, Guangxi, Hubei and Tibet.Since invading China, Yi Gei China agricultural, ecology, environment have brought serious threat.It is reported, the diffusion velocity of Eupatorium adenophorum can reach 60 kilometers/year, has has occupied a large amount of farmlands and forest land.Its harm comprises: complete stool is poisonous, harm agricultural animal husbandry production etc.; Reduce soil fertility, make land deterioration, crop yield significantly declines, and can cause grain drop in production; Branches and leaves are poisonous, harm people and other animal, and livestock can be caused a disease even lethal after eating by mistake.The appearance of Eupatorium adenophorum has caused huge economic loss.
The ecological problem bringing for Eupatorium adenophorum, country has taked a large amount of prophylactico-therapeutic measures, and the main method of preventing and treating has: artificial control, mechanical control, biological control, chemical prevention etc., but also do not find effective and economic method at present.In control, also seeking its value, control and utilization are combined, mainly comprise: medicinal, develop feed, make fertilizer, produce that agricultural chemicals, extract are made dyestuff, done marsh gas raw materials, manufacture medium density fibre board (MDF), cultured mushroom etc.Yet for various reasons, these measures all do not form large-scale production, the Rapid Expansion of Eupatorium adenophorum fails effectively to be contained.
As everyone knows, papermaking is the industry of a resource-hungry, and China is Yi Ge paper consumption big country, is the country of a plant resources critical shortage, the development and utilization of Papermaking Resource, meet the industrial policy that country first develops, there is very important social effect and economic worth.For a long time, Eupatorium adenophorum is being eliminated and applied in the process of research and development, ignoring it as the important value of fibre resources.According to research, Eupatorium adenophorum complicated component, but in its chemical composition, contain a large amount of celluloses, can be used for pulping and paper-making.
Chinese invention patent application " by the method for Eupatorium adenophorum papermaking " publication number is CN1986959A, be that Eupatorium adenophorum stem hammer is flat, add lime, add poach 220-260 hours, until then stem deliquescing mixes to copy with fragrant leaf after the bamboo pulp making as method and pulverizing and makes toilet paper.There is preparation method craftization in this patent, digestion time is long, is difficult to the shortcoming of large-scale production, and can only be for the production of low side paper-toilet paper.
Summary of the invention
Object of the present invention is exactly for above-mentioned the deficiencies in the prior art part; a kind of method of Eupatorium adenophorum bar extracting sulfuric acid salt true qualities paper pulp is provided; this method has realized Eupatorium adenophorum recycling; it is short that processing method has digestion time; advantage that can suitability for industrialized production; realize the object changing harmful to treasure, can effectively solve the defect that current Eupatorium adenophorum can not large-scale production paper pulp, be beneficial to the protection of ecological environment.
The object of the invention is to realize by following technical proposals:
A method for Eupatorium adenophorum bar extracting sulfuric acid salt true qualities paper pulp, is characterized in that, comprises the following steps:

2the liquid that S and water are made into carries out preliminary treatment, and this liquid be take over dry material quality and calculated: NaOH addition is 10～30%, Na
2s addition is 8～28%, and liquor ratio is 1:2～5, and pretreatment time is 10～90min;
Step 3, pretreated raw material and liquid are put into electrothermal pressure digester and are carried out boiling, from room temperature, are warmed up to 80～190 ℃, and heating-up time 40～120min is incubated 30～120min under maximum temperature;
Step 4, is slightly starched after boiling finishes, with filter screen, slurry is separated with cooking waste liquor when slurry temperature is 80～90 ℃, with 60～90 ℃ of clear hot-water washings;
Step 5, the flat vibrating screen screening the pulp of the slurry after cleaning, strained pulp dehydration, obtains Eupatorium adenophorum sulfate natural color pulp.
Further, in step 1, Eupatorium adenophorum bar is cut into the long tablet of 23～27mm.
Further, in step 5, wash disposed slurry flat vibrating screen screening the pulp, the wide 0.3mm of sieve seam, 1000 beats/min of vibration number, screening concentration 0.2～1%.
Compared with prior art; beneficial effect of the present invention is: this method has realized Eupatorium adenophorum recycling; it is short that processing method has digestion time; advantage that can suitability for industrialized production; realized the object changing harmful to treasure; can effectively solve the defect that current Eupatorium adenophorum can not large-scale production paper pulp, be beneficial to the protection of ecological environment.
