Method.
Background technology
Paper pulp, is the fibrous material obtained in Jing different processing methods with string as raw material.Can be according to processing method
It is divided into mechanical pulp, chemical pulp and chemimechanical pulp；It is divided into wood pulp, straw pulp, jute pulp, reed also dependent on 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..Typically it is used for manufacturing paper and cardboard.
Traditional slurrying refers to the method combined using chemical method, mechanical means or both, dissociates plant fiber material
Become the production process of true qualities or bleached pulp.The technical process for generally adopting is by plant fiber material crushing, boiling, washes
Wash, screen, bleach, purify, dry paper pulp.
Modern new development goes out a kind of bio-pulping method, first with special bacterial classification (whiterot fungi, brown rot fungus, soft-rot fungi) special orientation
Decompose lignin structure, after be aided with and mechanically or chemically dissociate remaining cellulose, then bleached.It is biological during this
Decompose, opened most of lignin, chemical method has been intended only as booster action, and chemical products used is than conventional method very
It is few, therefore few discharge can be accomplished or waste liquid is not discharged, it is a kind of environment-friendly pulping, free pulping method.
To sum up, a kind of health, culture, the manufacture method of medicinal paper paper pulp are studied particularly important.
The content of the invention
It is an object of the invention to provide a kind of health, culture, the manufacture method of medicinal paper paper pulp.
In order to realize object above, the technical solution used in the present invention is：A kind of health, culture, medicinal paper paper pulp
Manufacture method, it is characterised in that the raw material proportioning of the manufacture method is as follows：Poplar 10～50%, Eucalyptus 10～50%, horse hair
Pine 10～50%, potassium hydroxide accounts for the 1～4% of chip quality, and potassium sulfite accounts for the 2～6% of chip quality, and wherein hydrogen peroxide is used
Amount accounts for slurry 1～2%, the consumption 1.5～2.5% of ozone, and it is 0～1.5% that the consumption of chlorine dioxide accounts for the consumption of slurry, and whiterot fungi is accounted for
The 0.2～2% of slurry quality, green oxygen, surfactant account for the 0.03～0.1% of slurry quality, wetting agent jfc and account for the 0.05 of slurry quality
～0.1%, the potassium hydroxide and potassium sulfite are cooking liquor, and the hydrogen peroxide, ozone and chlorine dioxide are bleaching agent, described
Whiterot fungi is biologic product, and the green oxygen, surfactant are digesting assistant.
Further, the manufacture method includes comprising the following steps that：
(1) by poplar, Eucalyptus, masson pine peeling and cutting, scrubbed, extruding, tear are processed is processed into 10～30 millimeters of length,
Footpath wood fragments bar slightly less than 5 millimeters；
(2) batten mixes with water according to 1: 5～10, heats 30～50 degree of immersions, and the raw material after immersion is carried out with equipment
Squeeze and roll over rupture；
(3) whiterot fungi biological treatment liquid is cultivated, whiterot fungi biological treatment liquid is added in thick slurry, while adding green oxygen surface
Activating agent, wetting agent jfc carry out air stirring, and temperature is maintained at 30～45 degree；
(4) potassium hydroxide, potassium sulfite solution are added, boiling in short-term is carried out to mixed liquor, boiling temperature is 155～180
Degree；
(5) raw material defibrination after boiling, refining concentration 20～30%, into slurry 25～50 ° of SR of beating degree.Then high frequency ultrasound is used
Ripple homogenizer carries out homogenization, by the further texturing of fiber；
(6) bleaching process is initially charged hydrogen peroxide, is passed through ozone, and pulp density is maintained at 20～30%, and slurry temperature keeps
At 50～70 DEG C, it is passed through chlorine dioxide and adjusts pH value 6.5～7.5, opening ultrasonic wave homogeneous instrument carries out emulsifying operation；
(7) wash, subsequently into copy paper operation.
Further, the soak time of the step 2 is 1～3 hour.
Further, the mixing time of the step 3 is 20～30 hours.
Further, the digestion time of the step 4 is 0.5～1 hour.
Further, the time of the bleaching of the step 6 is 0.8～1.6 hour.
The beneficial effects of the present invention is：The present invention by being pre-processed to wood chip using microorganism, then with machinery
Method or chemical-mechanical pulping.Selectively decompose the lignin in (degraded) raw material, the damage of carbohydrate is reduced as far as possible
Lose.So as to reduce refining energy consumption, pollution of the papermaking wastewater to environment is reduced, improve pulp strength.
The present invention adopts ultrasonic wave homogeneous stirring technique, accelerates refinement, the texturing of fiber, promotes the homogeneous of paper pulp
Change.
The present invention can be used to make compound fertilizer using sylvite, potassium hydroxide as cooking liquor, sylvite and lignin material, reduce
Cost of sewage disposal, makes paper making process more environmental protection.
Paper pulp adds in process of production various auxiliary agents, adds Strong oxdiative material, whiterot fungi to be belonging to Basidiomycotina
Fungi, is one of the microorganism of timber main component of can degrading.Timber most of fiber during white rot still keeps complete,
And cellulose crystallity change is little.It is therefore envisaged that bio-pulping is carried out using to the selectively good whiterot fungi of lignin degrading,
The new way of pulping process can be opened up.Whiterot fungi except can lignin degrading be used to pre-processing, in addition to bio-bleaching, bio-pulping,
Also there is very strong capacity of decomposition to other organic xenobioticses,.
To sum up, this technique improves production process efficiency, and paper is aseptic, intensity is high, and whiteness is high, and good stability keeps holding
Long, paper and cardboard long-term storage are colour-fast.
