Description
Technical field
The present invention relates to field of papermaking processes, especially a kind of environment-protecting clean pulping process.
Background technique
Paper pulp is using plant fiber as raw material, through fibrous material made from different processing methods.It can be according to processing method
It is divided into mechanical pulp, chemical pulp and chemimechanical pulp；Wood pulp, straw pulp, jute pulp, reed can also be divided into according to fibrous raw material used
Slurry, sugarcane slurry, bamboo pulp, rag stock etc..Refined pulp, bleached pulp, unbleached pulp, high yield pulp1 can be divided into according to different purity again
Paper pulp, semi-chemical pulp etc. are generally chiefly used in manufacturing paper and cardboard.
There are many deficiencies during slurrying for traditional pulping process, such as: raw material are planted in traditional slurrying
Mainly in such a way that machinery blends, plant fiber can not be dissolved and be extracted well fibres by such production method
Out；During carrying out deep processing to paper pulp, it can not accomplish to eliminate the impurity in paper pulp well, to influence
The quality of paper is made and the waste water of slurrying can generate very big pollution, very big harm is generated to environment；For in advance at paper
Drying mode generallys use the mode of natural air drying, is easy to cause finished paper to be easy to happen fold in this way and is easy to appear between paper
The case where adhering to occurs.
The present invention is studied for these problems, devises a kind of environment-protecting clean pulping process, it is desirable to be able to improve
The quality of paper is made in the feature of environmental protection of paper and raising.
Summary of the invention
In order to overcome the shortage of prior art, the purpose of the present invention is to provide a kind of prevention and treatment puerperal fever and stimulating milk secretion kudzuvine root starch Chinese medicines
Formula and its processing technology.
The technical solution adopted by the present invention to solve the technical problems is: a kind of environment-protecting clean pulping process, processing step
It is rapid as follows:
Step 1: plant fiber decomposes；
Step 2: melting is heated in boiling；
Step 3: washing absorption decontamination；
Step 4: screening is extracted；
Step 5: peculiar smell is removed in bleaching；
Step 6: purification paper molding；
Step 7: drying and processing.
Preferably, a kind of environment-protecting clean pulping process；
The plant fiber decomposes the method for using bio-pulping, and plant fiber material is carried out at crushing by pulper
Then reason decomposes lignin structure with special strain special orientation, the special strain is mainly whiterot fungi, brown rot fungus and soft corruption
Bacterium；
Boiling heating melting is that the plant fiber after decomposing is placed in pulp digester, temperature be adjusted to for
80-100 degrees Celsius, boiling 6-8 hours；
The washing absorption decontamination is the technique for waste liquid in paper pulp being cemented out the paper pulp after the completion of boiling with water
Then process places synthesis zeolite adsorbent in the process of washing, carries out absorption discharge to the impurity in slurrying；
The screening, which is extracted, screens paper pulp by using close screening net of setting；
The bleaching goes peculiar smell that the paper pulp after screening is added chemical deodorant, is then stirred fusion, stirring fusion
Often it is 30 minutes, the plant peculiar smell in paper pulp is removed；
A kind of precipitating reagent for making impurity flocculate or precipitate is added in the purification paper molding, then can use floatation such as
Particulate floatation method isolates obtained precipitating or the dry solid content of flocculate process water is generally 0.01-1.5% (wt),
Preferably 0.1-1.0% (wt), meanwhile, in the concentrate for carrying out flash-pot, dry solid content is generally 1.0-50% (wt),
Preferably 2.0-15% (wt)；
The drying and processing is placed under heating blower pre- after purified treatment at paper, by by heter temperature tune
Wind-force drying is carried out to paper to 30-50 degrees Celsius.
Compared with prior art, beneficial effects of the present invention are as follows:
1. a kind of environment-protecting clean pulping process, firstly for the plant fiber of raw material extracting mode do not use it is traditional
The mode that machinery blends, and by the way of biological decomposition, lignin structure, the spy are decomposed using with special strain special orientation
Different strain is mainly that whiterot fungi, brown rot fungus and soft-rot fungi can effectively extract the fermentation of plant fiber contained in plant
Come, and reduce the generation of impurity, to improve the quality that paper is made.
2. to paper pulp carry out deep processing during, use washing absorption decontamination, screening extract, bleaching go peculiar smell with
And the purification molding deep processing mode of paper, the impurity in paper pulp can be carried out using synthesis zeolite adsorbent first
Absorption, then close screening net of setting sifts out impurity, finally carries out de-tasting processing to paper pulp by chemistry deodorant again, thus
The degree of purity of paper pulp is improved, it is final to improve the product quality that paper is made.
3. in advance at paper by the way of heating blower drying, on the one hand, the molding drying rate that product can be improved, from
And working efficiency is improved, on the other hand, it is not easy to make that absorption and the appearance of fold situation occurs between paper.
