Description
Technical field
The present invention relates to field of papermaking, more particularly to a kind of production technology of corrugated board.
Background technology
Corrugated board started from for 18 end of the centurys earliest.19th century, it has been found that not only light performance is strong for corrugated board, price
More general material is more cheap, and manufacture craft is simple, and purposes is more extensive.Moreover, corrugated board serve not only as be
The recoverable environmental protection type material being made of the wood-fibred that can be decomposed through operation of nature, while can also be recycled without influencing it
The performance of performance.Therefore people are enjoyed to favor.Corrugated board (case) is the environmental type packaging product that the whole world is generally acknowledged.
But rubble cardboard is in process of production, starched due to the use of recycling, contain substantial amounts of gluing thing and fiber section in slurry,
Easily wadding is poly- for gluing thing and fiber section, causes that paper machine operation rate is low, broken hole breaks, and paper is more, and paper flatness is low.Simultaneously as recycling
Fibre bundle is more in slurry, there are gap between fiber, causes manufactured paper with pulp paper kiss-coating amount big, big into paper steam gas consumption.
The content of the invention
For this reason, it may be necessary to which corrugated board paper flatness can be improved, improve paper machine operation efficiency by providing one kind, reduce paper and scrape
Glue amount, reduces into the corrugated board production technique of paper steam consumption.
To achieve the above object, a kind of production technology of corrugated board is inventor provided, is comprised the following steps, in papermaking
Polyacrylamide is added in sludge, after mixing, feeds the mixture into the slurry of paper to be manufactured into, manufactures paper with pulp as paper；
The polyacrylamide, paper mill sludge, the weight ratio of slurry are 1-3：50-85:800-1300.
Further, the polyacrylamide, paper mill sludge, the weight ratio of slurry are 2：60:938.
Further, the particle diameter of the paper mill sludge is 0.3-3mm.
Further, the paper mill sludge passes through sterilization treatment before use.
Further, the sterilization method is ultraviolet sterilization or more than 135 DEG C high-temperature sterilizations.
Further, the paper mill sludge and polyacrylamide are mixed by pipe-line mixer.
Further, the slurry is recycling paper pulp.
The prior art is different from, sludge and polyacrylamide are proportionally added into the slurry of paper to be manufactured into by above-mentioned technical proposal
Material, polyacrylamide carry out auxiliary to the fiber fines in slurry and sludge and keep so that sludge and fiber fines can fill
Into slurry between fibre bundle, the hole that is effectively filled between fibre bundle improves the flatness of paper, reduces and subsequently apply
The table glue dosage of glue process and the steam consumption of rear drying process.Polyacrylamide has also adsorbed gluing composition granule, avoids glue
The secondary wadding of glutinous thing gathers, and improves drainage and the reservation of slurry, and paper is resolved in reduction.Sludge particle can be effectively in binding fiber beam
Free water, with reference to water, reduce the water content in fiber, while itself heat transfer efficiency is high in the drying process for sludge particle,
The energy heat conduction efficiency much of that effectively improved after drying cylinder, reduces the dosage of drying section drying cylinder steam, saves operating cost.
Embodiment
To describe the technology contents of technical solution, construction feature, the objects and the effects in detail, below in conjunction with specific reality
Example is applied to be explained in detail.
Paper mill sludge used is the sludge that paper waste produces after treatment facility is handled in present embodiment.Papermaking is dirty
Containing plant nutrients such as substantial amounts of cellulose family organic matter and nitrogen, phosphorus, potassium in mud, and contain micro heavy and pathogen.
Embodiment 1
It is 0.3-3mm by particle diameter, the paper mill sludge 60kg after 135 DEG C of high-temperature sterilization treatments adds 2kg polyacrylamides
Amine, after pipe-line mixer is sufficiently mixed processing, adding 938kg will be manufactured into the recycling slurry of paper, uniformly mixed slurry
By feeding pump to wet end approach system, the dehydration of upper wet end, splenium squeezing, the drying of drying portion, table glue kiss-coating, calender press polish,
Batch and manufacture paper with pulp into paper.
Embodiment 2
It is 0.3-3mm by particle diameter, the paper mill sludge 70kg after ultraviolet sterilization is handled adds 2.5kg polyacrylamides,
After pipe-line mixer is sufficiently mixed processing, adding 1200kg will be manufactured into the recycling slurry of paper, and uniformly mixed slurry leads to
Feeding pump is crossed to wet end approach system, upper wet end dehydration, splenium squeezing, the drying of drying portion, table glue kiss-coating, calender press polish, volume
Take and manufacture paper with pulp into paper.
Embodiment 3
It is 0.3-3mm by particle diameter, the paper mill sludge 55kg after ultraviolet sterilization is handled adds 1.2kg polyacrylamides,
After pipe-line mixer is sufficiently mixed processing, adding 900kg will be manufactured into the recycling slurry of paper, and uniformly mixed slurry passes through
Feeding pump is to wet end approach system, upper wet end dehydration, and splenium squeezing, the drying of drying portion, table glue kiss-coating, calender press polish, batch
Manufacture paper with pulp into paper.
In the embodiment above, polyacrylamide carries out auxiliary to the fiber fines in slurry and sludge and keeps so that dirty
Mud and fiber fines can be filled into slurry between fibre bundle, and the hole being effectively filled between fibre bundle, improves paper
Flatness, reduce the table glue dosage of follow-up sizing process and the steam consumption of rear drying process.Polyacrylamide also adsorbs
Gluing composition granule, the secondary wadding for avoiding gluing thing gather, and improve drainage and the reservation of slurry, and paper is resolved in reduction.
Inventor has found at the same time, free water that sludge particle can be effectively in binding fiber beam, with reference to water, makes in fiber
Water content reduces, while itself heat transfer efficiency is high in the drying process for sludge particle, much of that can effectively improve the heat biography after drying cylinder
Efficiency is led, reduces the dosage of drying section drying cylinder steam, saves operating cost.
Above example carries out the production of corrugated board, and waste paper ratio reduces about 8%, and drying section drying cylinder steam uses gas
Amount reduces about 3% (0.05T/T).
To sum up, technique provided by the present invention can effectively increase the product quality of corrugated board, reduce production cost,
It is simple to operation, it can be promoted on a large scale.
