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 (EupatoriumadenophorumSpreng) 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 intrusion China, bring serious threat to China's agricultural, ecology, environment.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, and harm people and other animal, livestock can be caused a disease even lethal after eating by mistake.The appearance of Eupatorium adenophorum has caused huge economic loss.
For the ecological problem that Eupatorium adenophorum brings, country takes a large amount of prophylactico-therapeutic measures, and main prevention and controls has: artificial control, mechanical control, biological control, chemical prevention etc., but does not also find effective and economic method at present.While control, also seeking its value, control and utilization being combined, mainly comprising: medicinal, develop feed, make fertilizer, produce agricultural chemicals, extract makes dyestuff, do marsh gas raw materials, manufacture medium density fibre board (MDF), cultured mushroom etc.But 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 the country that a paper consumption big country is 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 eliminated and is applying in the process of research and development, have ignored its important value as fibre resources.According to research, Eupatorium adenophorum complicated component, but containing a large amount of cellulose in its chemical composition, can be used for pulping and paper-making.
Chinese invention patent application " method with Eupatorium adenophorum papermaking " publication number is CN1986959A, be by flat for Eupatorium adenophorum stem hammer, add lime, add poach 220-260 hours, until stem deliquescing, then obtained with such as method bamboo pulp and pulverizes fragrant leaf afterwards and mix to copy and make 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 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 achieves Eupatorium adenophorum recycling; it is short that processing method has digestion time; can the advantage of suitability for industrialized production; achieve the object changed harmful to treasure, effectively can solve current Eupatorium adenophorum can not the defect of large-scale production paper pulp, is beneficial to the protection of ecological environment.
The object of the invention is to be realized by following technical proposals:

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, and from room temperature to 80 ~ 190 DEG C, heating-up time 40 ~ 120min, is incubated 30 ~ 120min at the maximum temperature;
Step 4, is slightly starched after boiling terminates, and when slurry temperature is 80 ~ 90 DEG C, slurry is separated with cooking waste liquor by filter screen, with 60 ~ 90 DEG C of clear hot-water washings;
Step 5, the flat vibrating screen screening the pulp of the slurry after cleaning, strained pulp dewaters, and obtains Eupatorium adenophorum sulfate natural color pulp.
Further, in step one, Eupatorium adenophorum bar is cut into the long tablet of 23 ~ 27mm.
Further, in step 5, wash the screening the pulp of disposed slurry flat vibrating screen, the wide 0.3mm of sieve seam, vibration number 1000 beats/min, screening concentration 0.2 ~ 1%.
Compared with prior art; beneficial effect of the present invention is: this method achieves Eupatorium adenophorum recycling; it is short that processing method has digestion time; can the advantage of suitability for industrialized production; achieve the object changed harmful to treasure; effectively can solve current Eupatorium adenophorum can not the defect of large-scale production paper pulp, is beneficial to the protection of ecological environment.
