Description
Technical field
The invention belongs to field of papermaking, and in particular to a kind of fennel seeds straw pulp plate and preparation method thereof.
Background technology
Fennel seeds category annual plant is that one kind being easy to regenerated green resource, about 300,000 mu of national cultivated area, fennel fruit
After fragrant seed is utilized as fragrance by picking, the stalk of fennel seeds is not used by sufficiently effective but, is discarded or is burned
Seldom as other purposes fennel seeds stalk is made the comprehensive utilization of pulp board in processing, will improve the whole of fennel seeds and passes through
Ji benefit.
The paper industry in China is in a fast growth phase, and the total output of paper and cardboard is substantially less than always overall consumption
Amount, year, paper consumption figure increased by 12% or more well below World Developed Countries level to the demand average year of paper per capita.
China is as the maximum paper country of consumption in the whole world and producing country, but the forest reserves are rare, and wood pulp papermaking raw material is deficient
Weary, 65% raw materials for production need import pulp and waste paper to make up the notch of raw material.In the recent period, international market pulp price is universal
Rise, increases the cost of papermaking.Currently, numerous domestic papermaking enterprise mainly replaces import using the especially careless plasmoid of non-wood pulp
Wood pulp is to reduce production cost, and most of to rely on import, market has openings is big, is developed and used to fennel seeds straw pulp plate, development
It has a extensive future.
The fiber quality that careless plasmoid mechanical pulping process existing at present obtains is poor, it is difficult to meet the strong of final market product
Scale is accurate；Such as improving pulp property will use chemical agent to carry out boiling, bleaching, can destroy ecological environment, increase boiling
The control of the pollution sources such as waste liquid and treatment cost.
The present invention is intended to provide a kind of method that pulp board is prepared as raw material using fennel seeds stalk, made from this method
Intensity of the intensity of pulpboard higher than current market sales of careless class pulpboard.
Invention content
Technical problems based on background technology, the present invention in view of the shortcomings of the prior art, by years of researches and
Experiment, and optimize the condition by raw material proportioning and technique, one kind is provided and prepares pulp board using fennel seeds stalk as raw material
Method, using pulpboard made from this method intensity higher than current market sales of careless class pulpboard intensity.
Technical scheme is as follows：
A method of preparing pulp board using fennel seeds stalk as raw material：
Preparation section includes successively：Stock, steam blasting, defibrination, screening the pulp, papermaking；
The stock refers to after fennel seeds seed has been picked, and fennel seeds stalk is cut into the short material of 2-4cm by stock-cutter, by shaking
Enter steam blasting tank after screening out dirt removal of impurities；
The steam blasting is that the raw material cut is directly heated with water vapour, after boosting to 1.0-3.0MPa, pressurize 1-20min
After carry out explosion, fennel seeds straw pulp board raw materials is made；
The defibrination refers to the raw material obtained after steam blasting, is ground and is slurried with fiberizer, the slurry pulping degree after control mill
20-40oSR；
The screening the pulp refers to that slurry is screened by pulp screen, and removing coarse fiber and its impurity becomes screened stock；
The papermaking refers to that slurry obtained feeding pulp machine is manufactured paper with pulp, and is dried to the pulpboard of moisture 13% or so.
Preferably, further including fermentation procedure before papermaking：
It is inoculated with mesophilic Sphingobacterium according to inoculum concentration 1%, is fermented 2-3 hours；
The invention has the beneficial effects that：
The fiber quality that careless plasmoid mechanical pulping process existing at present obtains is poor, it is difficult to meet the intensity scale of final market product
It is accurate；Such as improving pulp property will use chemical agent to carry out boiling, bleaching, can destroy ecological environment, increase cooking waste liquor
The control of equal pollution sources and treatment cost.The present invention in view of the shortcomings of the prior art, by years of researches and experiment, and excellent
Change the condition by raw material proportioning and technique, a kind of method preparing pulp board as raw material using fennel seeds stalk is provided, uses
Intensity of the intensity of pulpboard made from this method higher than current market sales of careless class pulpboard.
