Abstract
The invention discloses a kind of novel renewable fluting medium preparation methods, the invention belongs to the crossing domains of paper industry and food industry, the characteristics of present invention combination agricultural waste material fibre morphology and chemical constituent, use it to and prepares fluting medium, both the Utilizing question of agricultural waste material had been solved, paper making raw material is saved again, and the fluting medium surface smoothness being prepared is high, intensity is good, waterproof and dampproof anti-mildew.
Description
Technical field
The invention belongs to the crossing domains of paper industry and food industry, are related to a kind of novel renewable fluting medium preparation
Method.
Background technique
A kind of corrugated case essential packing container as tradition, has also been employed that century-old and firmly gets favor.
Corrugated board is the raw material for making corrugated case, and fluting medium is one of the important composition material for producing corrugated board.Watt
Stupefied body paper requires fiber bonding strength good, and paper is smooth, there is preferable tightness and stiffness, it is desirable that has certain elasticity, to guarantee
Manufactured carton has shockproof and voltage endurance capability.The fluting medium produced at present is divided into 6 kinds according to slurrying mode: the whole America is useless, beautiful
Useless+state is useless, U.S. is useless+and straw pulp, state be useless+straw pulp, U.S. be useless+state is useless+straw pulp and herb slurry.With the useless production high-strength corrugated base paper of U.S., or
Person is to add the useless production high-strength corrugated base paper of U.S. that can produce high-quality corrugation using non-pollution pulping process using high-quality wheat straw as raw material
Body paper, but due to the useless demand sharp increase of U.S. on domestic market, has there is the situation that supply falls short of demand and appreciates in the useless market of U.S..With
U.S. useless (and Russia is useless, day is useless, Europe is useless) and state give up and can only produce the not very high fluting medium of some intensity requirements for raw material.It is useless with state
The fluting medium of production is because raw material repeatedly recycles use, quality decline, can only produce in low fluting medium.
Summary of the invention
The present invention provides a kind of novel renewable fluting medium preparation method, can solve pointed in background technique ask
Topic.
The object of the present invention is to provide a kind of novel renewable fluting medium preparation methods, solve current crop waste
Object 70% had not only polluted the problem of environment but also waste of resource as garbage disposal.
The technical scheme adopted by the invention is that the method that agricultural waste material prepares fluting medium, specifically according to following
Step is implemented:
Step 1, agricultural waste material washing is faded and mass concentration is made as 1.0~1.2% fibre stuff, then removed
After impurity raw material impregnated in NaOH solution, be dehydrated be concentrated to mass concentration be 5~15%, then carry out by several times slightly discongest,
Sub-wire processing is exchanged views, agricultural waste material fibre stuff is obtained；
Step 2, the agricultural waste material fibre stuff that step 1 obtains is mixed with the vegetable-fibre slurry Jing Guo defibrination process
Chemical addition agent is added after conjunction, is then diluted with water to the slurry that mass concentration is 0.5~1.0%, finally uses wet forming
Mode manufactures paper with pulp to arrive novel renewable fluting medium.
Beneficial effects of the present invention:
The method of the present invention uses agricultural waste material for raw material, and agricultural waste material is mostly heteroproteose cell, to quality of finished paper without
Contribution, will cause that quality of finished paper is very poor instead, therefore the present invention removes the marrow of agricultural waste material, then prepares fluting medium
With slurry.High pulping yield is obtained under conditions of whole normal pressure, yield reaches 75% or more, than corn stover chemical pulping
Yield 50% improves 50 or more percent.
And 1.318~2.224km, ring are reached with the fluting medium fracture length of high yield pulp1 fluting medium slurry preparation
Pressure index has reached 6.62~13.02mNm/g, and quality preferably (under equal conditions, is split with fluting medium prepared by market waste paper
Break a length of 2.13km, ring crush index 6.19mNm/g).The method of the present invention whole process normal pressure is reduced departing from hyperbaric environment
The dangerous investment with equipment of production, saves energy consumption, reduces production cost.
Since other chemical assistants not being added in the method for the present invention, so liquid waste processing difficulty substantially reduces.This method
The waste liquid generated after step 2 roll mill grinding is extractable Ke Xunhuanliyong, saves water resource；Carry out fermentation heap can also be collected
Fertilizer.
Since waste fibre stuff yield is too low, it is not used for preparing fluting medium always.The present invention improves discarded
Waste is used for fluting medium preparation, overcomes technology prejudice by fibres slurry pulping yield.
The method of the present invention compensates for asking for the current high-quality production of fluting base paper heavy dependence foreign countries' imported waste paper in China
Topic, and turn waste into wealth, realize the pollution problem that air is alleviated while resource reclaim recycles.
Specific embodiment
Embodiment 1
Step 1, by the air-dried waste washing for impregnating 2h or more is faded, the fibre that mass concentration is 0.8% is made in removing
Tie up slurry, then use Mechanical Method to remove fruit seed shell, seed, cleaning after carpopodium, be dehydrated and be concentrated to mass concentration as 5%, then into
Row slightly discongests by several times, exchanges views sub-wire processing, exchanges views sub-wire processing and is handled using double screwy roller grinded-paste machine, grinding clearance
0.5mm, obtaining length is 0.5~1.5mm agricultural waste material fibre stuff；
Step 2, at the agricultural waste material fibre stuff and the intermittent valley beater defibrination of use step 1 obtained
The length of reason is that cation polypropylene acyl is added after 1.2~2.0mm does not float broad-leaved wood fiber slurry in mass ratio and be 7:3 mixing
Amine, gum rosin, aluminum sulfate and mould inhibitor, wherein cationic polyacrylamide additional amount be agricultural waste material fibre stuff with not
The 1.8% of broad-leaved wood fiber slurry total amount is floated, gum rosin is agricultural waste material fibre stuff and does not float broad-leaved wood fiber slurry
The 1.2% of total amount, aluminum sulfate is waste fibre stuff and not float the 2.4%. mould inhibitor of broad-leaved wood fiber slurry total amount be apple
Fruit juice waste fibre stuff and the 0.7% of broad-leaved wood fiber slurry total amount is not floated, being then diluted with water to mass concentration is
0.6% slurry is finally manufactured paper with pulp using wet forming mode to get fluting medium is arrived.
