Description
Technical field
Field is manufactured the present invention relates to kraft paperboard, more particularly to a kind of high-grade kraft liner cardboard paper
High efficiente callback sizing process.
Background technology
Wastewater treatment sludge quantity is very big caused by wastepaper pulping and papermaking in paper industry, generally finished paper yield
20%-30%, the quality of sludge application are critically important to the cost impact of finished product.The method of domestic processing sludge mainly has two at present
Kind, first, using landfill is transported outward after filter press dehydration, burned second, being delivered to power station after press filtration, although above two method
Technology all comparative maturity, practicality, but still existing defects, the first landfill sludge need to take the soil of large area, the dirt after landfill
Foul smell caused by mud spontaneous fermentation can also secondary pollution air, the second sludge after filter press press filtration delivers to power station and burnt
Burn, though the energy can be produced, save coal consumption, caused solid waste reprocessing cost is higher after burning, also results in simultaneously
The waste of fiber and filler in sludge, and the sludge that burns can only burn up the organic components in sludge, such as fiber fines, half
Cellulose and organic chemistry auxiliary agent, and can also be produced after inorganic matter component such as filler, the coating of coating paper, china clay burning substantial amounts of
Waste residue, waste residue also need to handle again.So how the cost-effective disposal of sludge progress to wastewater treatment is environmental project
The problem that boundary and papermaking circle are paid close attention to jointly, it is a kind of using new technique that biological recovery slurry is i.e. dirty that R ＆ D design is taken charge of still
Mud is used in the production of high-grade kraft liner cardboard paper, turns waste into wealth, and comprehensively utilizes waste material.
The content of the invention
In view of the foregoing, the invention provides a kind of high efficiente callback sizing process of high-grade kraft liner cardboard paper, this work
Skill uses new technique that biological recovery is starched to the production for high-grade kraft liner cardboard paper, biological recovery slurry part substitution waste paper
As raw materials for production, by producing high-grade kraft liner cardboard paper after chemical treatment and technique adjustment, waste paper is reduced
Usage amount, save cost.
To reach above-mentioned purpose, the technical solution adopted for the present invention to solve the technical problems is：
A kind of high efficiente callback sizing process of high-grade kraft liner cardboard paper, comprises the following steps：
（1）First by the waste water of workshop discharge successively by fine fack, inclined wire, coagulating basin processing, the waste water after processing enters just
Dirt pond is precipitated, and sludge caused by precipitation enters sludge storage pool, and the waste water after precipitation reclaims after carrying out subsequently aerobic, Anaerobic Treatment
Utilize, follow-up caused sludge is back to sludge storage pool again；
（2）The sludge part taken out in sludge storage pool is starched as biological recovery, and biological recovery slurry is placed on into biological recovery stock tank
The middle production for being used for high-grade kraft liner cardboard paper as 2% or so waste paper and original waste paper；
（3）In step（2）Middle biological recovery slurry is as the various weight impurity needed before raw material production in starching biological recovery
And sicker carries out purifying removing glue processing；
（4）Complete step（3）New coating agent is added in biological recovery stock tank afterwards, to ensure quality of finished paper；
（5）Finally paper is produced into according to the production procedure of kraft liner cardboard paper.
Further：The production procedure of described kraft liner cardboard paper includes streaming, shaping, squeezing, dry and applying glue.
Further：Surface layer slurry needs to carry out further purification process before approach system is entered, and is adopted in purification process
With compact pot type and drum-type scummer to improve slurry cleanliness factor, after scummer exit add dyestuff, contaminated by frequency conversion
Material pump accurately controls dye dosage.Face core base pastes add PAM-bentonite microparticles in approach system
The auxiliary materials such as retention and drainage aid agent, modified starch improve slurry retention and follow-up paper strength.
Further：Each layer slurry after approach system by flowing full air-cushioned head box enter respective forming net carry out into
Shape is dehydrated, and increases shake system in forming net porch, is improved interlacing degree of the fiber in net part forming, is ensured paper web banner
Quantitative and even, finally select suitable composite pressure opposite, sandwich layer to carry out compound, face, core, bottom are then carried out by compound big roller
Layer it is compound.
Further：Squeezing using three squeezing, one pressure for the nip of three roller two K pressure, two pressure be advanced shoe press,
Three pressures are blind drilled press.
Further：Process of Applying Glue uses rational drying curve, is slowly increased the temperature of each drying cylinder, controls paper web moisture
8.0% or so.
Due to the utilization of above-mentioned technical proposal, the present invention compared with prior art this technique productions produce into the resistance to of paper
Broken index >=3.8kPam2/g；Ring crush index >=10.5Nm/g；Smoothness >=7s；Inter-layer bonding force >=600J/m2.This work
The research and development of skill have recycled substantial amounts of sludge recovery slurry so that the utilization rate of sludge greatly improves so that waste paper dosage reduces
2%-3%, wherein amount of filler also reduce 5%, fines retention >=30%.Paper per ton is made using new technique of the present invention
Cost 20-25 members can be reduced on the basis of original, it is contemplated that annual cost-saved ten thousand yuan of 500-700, greatly reduce production
Cost, improve economic well-being of workers and staff.
