Description
Technical field
The present invention relates to a kind of preparation method of papermaking special environment protection stalk pulping agents, belongs to the preparation of stalk pulping agents
Technical field.
Background technology
China's paper making raw material is extremely in short supply, and the paper making raw material such as timber, wood pulp, commercial pulp, waste paper largely relies on import, seriously
Have influence on the security of paper industry；And China's stalk resource is very abundant, it can greatly alleviate China's papermaking for pulping and paper-making
Raw material situation in short supply.Stalk pulping technique has expanded pulping technique, oxidizing process cleaning pulping technology, DMC pulping techniques at present
Deng, but high energy consumption, pollution weight, the problems such as slurry yield low strong to fiber destruction power be present in these stalk pulp and paper technologies.
Physical slurrying is a kind of currently used method, and physical straw slurrying needs the process in mechanical thread rolling slurrying
In, inside pulping agents molecule infiltrated fiber, make fiber that thread rolling to a certain degree occur into slurry.Process in thread rolling into slurry
In, substantial amounts of hydroxyl separate out, increase cellulosic molecule in hydrogen bond concentration.Meanwhile dissociate the major part in plant tissue
Lignin and part hemicellulose, fiber therein is set to separate each other so as to form the process of paper pulp.In the help of pulping agents
Under, the mobility increase of cellulose chain, be advantageous to cellulose and change to ordered structure.Meanwhile portion of cellulose is rearranged,
In this case, chemi-mechanical pulp be more beneficial for full chemical pulp mixed-forming, and produce product.But presently used slurrying helps
Agent solubility property is poor, slower to raw material infiltration, and lignin degradation and dissolution time are longer, cause slurry yield low, and can produce and be difficult to
The black waste liquid of processing, environment is seriously polluted after discharge.
Glusulase is the mixed enzyme with bioactivity found from the prolixity capsule and alimentary canal of snail, and it contains cellulose
Enzyme, pectase, Alpha amylase, proteolytic enzyme, seminase, Galactanase and aminotransferase etc..Therefore make
Pulping agents are prepared with its auxiliary, to effectively decomposition and dissolved lignin, slurry yield is improved, has great importance.
The content of the invention
The technical problems to be solved by the invention：Slower, lignin degradation is permeated to raw material for presently used pulping agents
It is longer with dissolution time, cause slurry yield low, and reluctant black waste liquid can be produced, the disadvantage of environment is seriously polluted after discharge
End, there is provided a kind of glusulase isolated from snail digestive juice is standby, then toasts collection lard, inhales method extraction castor using fat
Sesame oil, submissive softening agent is made with polyacrylamide, carclazyte blending, then standby enzyme liquid and softening agent are mixed, in microorganism
The lower fermentation reaction of effect, is made pulping agents.Pulping agents produced by the present invention quickly can be penetrated into inside stalk fibre, soft
Make the mobility of cellulose chain increase in the presence of soft dose, change beneficial to its ordered structure, hydrogen bond is dense between increasing cellulosic molecule
Degree, then the most of lignin and part hemicellulose in plant tissue are dissociated by glusulase, fiber therein is divided each other
From being formed beneficial to slurry, improve slurry yield, had broad application prospects.
In order to solve the above technical problems, the present invention is using technical scheme as described below：
（1）50~60 white jade snails are selected, are put it into ceramic pot, and 1000~1200mL is added into ceramic pot
Deionized water, then 40~50g tea oils are added dropwise into deionized water, Nature enemy 3~5 days are stood, it is miscellaneous in vivo to treat that snail spues
After thing, hand-dissection, snail glandula digestive is taken out, and extrude wherein digestive juice, collected digestive juice and be put into horizontal centrifuge, with 9000
~9500r/min rotating speeds centrifuge 15~20min, and isolated upper strata glusulase clear liquid is standby；
（2）Build high 1.0~1.5m baker with stone heap, pear tree branch first lighted inside baker, to furnace wall plus
After 3~5h of heat baking, in-furnace dust cinder is removed, takes one piece of 3~5kg pork to be linked into stone stove, the heat pair distributed using furnace wall
Cube meat is toasted, and collects the grease dripped from cube meat, and standing treats its natural coagulation；
（3）Grease after above-mentioned solidification is uniformly applied on the square glass plate that two pieces of length of sides are 30cm, control applies
It is 5~10mm to smear thickness, and tile one layer the castor bean after pulverizing on the smearing grease face of one piece of glass plate wherein, laying depth
For 3~5mm, then by the smearing grease face pressure of another piece of glass plate in castor-oil plant seed layer, then press 3~5kg's on a glass
Brick, standing adsorption 7~9 days, and every other day change a castor-oil plant seed layer；
（4）After to be adsorbed, castor bean is removed, the oil layer on glass plate is scraped with scraper, obtains compound lard,
Count in parts by weight, weigh 30~45 parts of compound lards, 10~15 parts of polyacrylamides, 20~30 parts of carclazytes, be sequentially loaded into height
Press in homogenizer, after 90~100MPa 20~30min of pressure homogenization, discharging, derived from the submissive softening agent of system；
（5）It is 10 in mass ratio:1:1, by the submissive softening agent of above-mentioned self-control, standby glusulase clear liquid and dodecyl sulphur
Sour sodium, which is sequentially loaded into reactor, is used as mixed substrates, then accesses whiterot fungi in mixed substrates for 10% by inoculum concentration, and sealing is anti-
After answering kettle, after heat-preservation fermentation reacts 5~7 days at 30~40 DEG C, discharging, freezed and done at -50~-40 DEG C with vacuum freeze-drying machine
After dry 40~50min, 1~2h of grinding in ball mill is put into, crosses 100 mesh standard sieves, sieving powder is packed, produces and makes after packaging
Paper special environment protection stalk pulping agents.
The application process of the present invention：Count in parts by weight, weigh 5~10 parts of papermaking special environment protections produced by the present invention respectively
Stalk pulping agents, 45~50 parts of pulping raw materials and 48~55 parts of running water, are sequentially placed into digester, at 160~165 DEG C
80~100min of boiling, obtained slurry is separated by filtration after boiling.Pulping agents of the present invention are to pulping raw material quick permeation, with other sides
Method improves 28~30% compared to slurry yield, and Kappa number reduces 8.6~10.2, pulping process non-pollutant discharge, no poison ring
Protect, be worthy to be popularized and use.
Compared with other method, advantageous effects are the present invention：
（1）Preparation process of the present invention is simple, and gained pulping agents are fast to raw material seepage velocity, effectively shorten lignin degradation
And dissolution time；
（2）Pulping agents of the present invention are high using rear slurry yield, and no black waste liquid produces, environmentally safe.
