Description
Technical field
The present invention relates to the reclaimings of corrugated paper to produce field, and in particular to a kind of to recycle the production work for making corrugated paper again
Skill.
Background technique
Corrugated paper is the plate object being bonded by the corrugated paper of sheet lining and the waveform formed by corrugated roller processing,
It is generally divided into two class of single wall corrugated board and double-layer corrugated cardboard, is divided into according to the size of corrugation: A, five seed type of B, C, E, F.Corrugation
The invention and application of paper have more than 100 years history histories, and at low cost, light weight, processing is easy, intensity is big, printing adaptability sample is excellent
It is good, storage convenient in carrying the advantages that, 80% or more corrugated paper can be used as food or number by reclaiming, corrugated paper
The packaging of code product, relatively environment-friendly, use is relatively broad.
Fluting medium is one of the important composition material for producing corrugated board.Fluting medium requires fiber bonding strength good,
Paper is smooth, there is preferable tightness and stiffness, it is desirable that has certain elasticity, to guarantee that manufactured carton has shockproof and resistance to pressure energy
Power.Fluting medium is to constitute raw material paper used in corrugated board corrugated core, it is machined by corrugation, by being heated to 160
~180 DEG C of Corrugator roller plays core paper stupefied into corrugated paper.Fluting medium has roll web and sheet paper, quantification of 112~200g/
M2, fibr tissue is uniform, and paper web thickness is consistent, bright yellow color, there is certain bulk, stiffness with higher, ring crush intensity
And water imbibition, excellent fitting adaptability.Generally with true qualities leaf wood semi-chemical pulp, cold alkali slurry or true qualities alkaline straw-pulp or it is equipped with
Secondary stock is manufactured paper with pulp after fast beating on feeding cylinder multi-cylinder paper machine.It is mainly used as the corrugated core of corrugated board
Layer (middle layer), plays an important role to the shockproof properties of corrugated board, can also be used alone as the package paper of breakables.
Paper industry has a jargon: seven points of slurrying, three points of copy papers.It can be seen that the importance of stock quality, pulping process is also to make
The quality at the Key Quality control point of paper, slurry determines the quality of paper.In order to reach the mesh for reducing cost and environmental protection and energy saving simultaneously
, those skilled in the art are dedicated to developing a kind of production technology for recycling and making corrugated paper again, and simple process is easy to operate,
Cost is greatlyd save by the recycling and reusing of corrugated paper, while guaranteeing final product quality, improves corrugated paper intensity and water-resistance.
Summary of the invention
Goal of the invention: in order to overcome the deficiencies in the prior art, the present invention provides a kind of recycle and makes corrugated paper again
Production technology, have the characteristics that simple process, easy to operate, energy conservation and environmental protection, saved significantly by the recycling and reusing of corrugated paper
About cost, while guaranteeing final product quality, improve corrugated paper intensity and water-resistance.
Technical solution:
It is a kind of to recycle the production technology for making corrugated paper again, include the following steps:
Step 1: recycling slurrying:
(1) boiling is carried out after crushing waste and old corrugated paper, the mass ratio of water and waste paper is 5.5~6.5 in digestion process, is stirred
It mixes and is heated to 70 °~80 °, obtain secondary stock after mixing；
(2) secondary stock washed, screened, obtain paper pulp after concentration and removal；
Step 2: reinforcing agent being added into paper pulp, is uniformly mixed, and is warming up to 95 °~105 °, keeps the temperature 10~20 minutes；
Step 3: aluminum sulfate solution stirring is added in the paper pulp of retrogradation, drying forming is carried out after mixing, obtains
Corrugated paper semi-finished product；
Step 4: top sizing processing is carried out to corrugated paper semi-finished product；
Step 5: being dried the corrugated paper semi-finished product after top sizing, after standing 20~25 hours after drying
Finished product is obtained, is sheared after blanking, pile, is put into warehouse storage.
Further, the reinforcing agent in the step 2 uses DH-1 reinforcing agent.DH-1 is a kind of novel plastics enhancing
Agent, be it is a kind of can be very big by two kinds of nature differences by chemistry and (or) physical action, be not easy originally the material combined compared with
The substance being securely joined with.DH-1 can not only make resin closely coupled and reach good mechanical strength, and can be improved
The mobility of the dispersibility of resin, resin system is improved.These factors be all conducive to increase material product mechanical strength,
Apparent mass and processing performance.
Further, in order to improve pulp brightness, in the step 1 (1), it is 1% that mass fraction is added in secondary stock
The magnesium sulfite that~2% sulfurous acid and mass fraction is 2%~3%, is heated with stirring to 110 °~115 °, and step 1 (2)
Middle carry out chemical washing removes residue chemistry drug.
Further, it is 15%~20% aluminum sulfate solution that mass fraction is selected in the step 3.
The utility model has the advantages that a kind of recycling provided by the invention makes the production technology of corrugated paper, compared with prior art, tool again
There is following technical effect: having the characteristics that simple process, easy to operate, energy conservation and environmental protection, it is big by the recycling and reusing of corrugated paper
Big save the cost, while guaranteeing final product quality, corrugated paper intensity and water-resistance are improved, there is very good economic benefit and make
Use effect.
Specific embodiment
Below with reference to embodiment, the present invention will be further explained.
It is a kind of to recycle the production technology for making corrugated paper again, include the following steps:
Step 1: recycling slurrying:
