Abstract
The invention provides a corrugated board manufacturing method. A corrugated board is made of the following raw material of 85% of waste paper and 15% of waste pulp slag. The manufacturing method mainly comprises steps of smashing, compressing, squeezing, drying and sizing. The beneficial effects are that raw material is saved; waste pulp slag can be fully utilized, so an aim of energy-saving and cost-reducing is achieved; and demands of downstream customers can be met.
Description
Technical field
The present invention relates to the technical field of papermaking, more particularly, to a kind of corrugated board manufacture method.
Background technology
Corrugated board is the adherend of a multilamellar, and it is minimum to be made up of one layer of waveform refill and a layer paperboard.Corrugated board has very high mechanical strength, can support by the collision in goods handling process and stagger along, mainly for the manufacture of the outer package of carton, the sandwich and delicate articles of carton.Corrugated board temperature influence is little, shading performance is good, is typically affected also less by humidity.Range of application is widely.
The quantity of China's corrugated board production manufacturer is continuously increased a few days ago, and used in paper-making process, the raw material such as timber is all non-renewable resources.In order to realize the sustainable development of paper-making industry, resource reclaim recycles and is particularly important.
Content of the invention
It is an object of the invention to provide one kind utilizes wasted paper material, the method that mode with low cost produces corrugated board product.
The present invention is achieved through the following technical solutions：A kind of corrugated board manufacture method, its feature is in comprising the following steps：
Originally adopt 85% waste paper and 15% useless slurry slag
Waste paper is smashed in pulper；
15% useless slurry slag is mixed with secondary stock by discongesting, screening, purifying, being evacuated in pulper by stock pump；
Carry out removing again Slag treatment by HC Cleaner to the above-mentioned waste paper smashed, screenings；
Remove the paper pulp of slag charge through multi-stage screening；
Paper pulp after the compression screening of polydisc thickener；
By paper machine stock tank agitating pulp；
The paper pulp being stirred by approach system conveying, and pass through press section press；
Paper pulp after squeezing is dried；
Applying glue is carried out to dried paper pulp by sizing applicator；
Paper pulp after applying glue is dried with formation high-strength corrugated board plate.
Described high-strength corrugated paper board manufacturing method it is characterised in that useless slurry slag through screenings processing system again secondary recovery using specifically including：
Useless slurry slag is concentrated；
Useless slurry slag is discongested；
Useless slurry slag is screened；
Useless slurry slag is purified；
Secondary recovery utilization is carried out to the useless slurry slag after processing；
Preferably, also include carrying out applying glue by sizing applicator, front resin added is 2.5kg/t paper, reverse side resin added is 2.5kg/t paper.
Beneficial effects of the present invention are：Save raw material, reduced water, electricity, vapour equal energy source consumption, reached energy-saving purpose, and met the needs of downstream client.
Specific embodiment
In order to reduce the energy resource consumption of corrugated board raw material, embodiments provide a kind of corrugated board raw material.In the inventive solutions, by corrugated board is made using imported waste paper and domestic waste paper and useless slurry slag, thus having reached energy-saving purpose, with specific embodiment, technical scheme is illustrated below.
Embodiments provide a kind of corrugated board raw material, a kind of corrugated board raw material, this corrugated board raw material includes：85% waste paper and 15% useless slurry slag.
With specific embodiment, the present invention will be described below：
The embodiment of the present invention additionally provides a kind of corrugated board manufacture method, and it is just, comprises the following steps：
Step one, 85% waste paper is smashed in pulper；
Step 2,15% useless slurry slag is passed through discongest, screen, purifying, being evacuated in pulper by stock pump and mixed with secondary stock；
Specifically include：Useless slurry slag is concentrated；Useless slurry slag is discongested；Useless slurry slag is screened；Useless slurry slag is purified；Secondary recovery utilization is carried out to the useless slurry slag after processing；
Step 3, the above-mentioned waste paper smashed, screenings are carried out remove Slag treatment again by HC Cleaner；
Step 4, the paper pulp after the compression screening of polydisc thickener；
Step 5, through multi-stage screening remove slag charge paper pulp；
Step 6, pass through paper machine stock tank agitating pulp；
Step 7, the paper pulp being stirred by approach system conveying, and pass through press section press；
Step 8, to squeezing after paper pulp be dried；
Step 9, applying glue is carried out to dried paper pulp by sizing applicator；
Specifically include：Applying glue is carried out by sizing applicator, front resin added is 2.5kg/t paper, reverse side resin added is 2.5kg/t paper.
Step 10, formation corrugated board is dried to the paper pulp after applying glue.
Have the advantages that unit consumption is low, intensity is high, reduce waste paper by the corrugated board that said method is produced to consume, and raw material has been saved using above-mentioned papermaking process, reduce water, electricity, vapour equal energy source consumption, reached energy-saving purpose, and met the needs of downstream client.
The present invention is not limited to above-mentioned preferred forms; anyone can draw other various forms of products under the enlightenment of the present invention; however, making any change in its shape or structure, every have technical scheme identical or similar to the present application, is within the scope of the present invention.
