Description
Technical field
The present invention relates to paper industry technical field of resource comprehensive utilization, be specifically related to a kind of use regenerated papermaking mud to produce fluting medium and production method.
Background technology
Along with improving constantly of the level of economic development, paper-making industry is developed rapidly, and while bringing economic benefit, also creates problem of environmental pollution, and the water pollutions of paper industry, in all kinds of industry, comes out at the top; The pollutions such as waste gas, solid waste and noise, also more serious.
Be in the process of raw material Production and Packaging paper and paperboard with waste paper, can produce waste water, wastewater treatment can produce mud.Typical waste water treatment process comprises just heavy, Aerobic Process for Treatment, can produce primary sludge and secondary sludge in production process.The oven-dry weight of regenerated papermaking primary sludge is generally 0.5% ~ 2% of product gross mass, primarily of fiber fines, filler and impurity composition, in prior art, through purifying alternative few fibers raw material for production of fluting base paper.Papermaking second pond mud oven-dry weight is generally 0.5% ~ 1% of product gross mass, mainly containing protein, polysaccharide, fiber fines and inorganic matter, in light brown, there is not yet the report to its resource efficiency utilization before the present invention.Sludge treatment from the past as just sewage disposal unit develop into Designing Sewage Treatment Plant, run to have to top-priority important step.At present, sludge pollution is a primary pollution source during paper industry pollutes.Paper mill sludge must be disposed, and the mud comprising primary sludge mainly adopts land-fill method to dispose at present; Because environmental requirement is more and more higher, Sludge landfill easily causes secondary pollution to environment, and land occupation, start to be restricted.Increasing researcher carries out comprehensive utilization of resources to mud, to reduce the pollution to environment in exploration.Such as:
CN101949105A discloses a kind of papermaking sludge paperboard and preparation thereof, is fully mixed by the mud from intermediate pool, prepare papermaking sludge paperboard in hydrabrusher with textile waste staple fibre.
CN103102053A discloses a kind of Resourceful treatment method of paper-making sludge, through precipitation concentration, dewater, break up and utilize with coal mixing after-combustion, and remaining waste residue is used for the raw material of cement or brick after Thorough combustion.Achieve making full use of paper mill sludge organic matter and inorganic matter, accomplish the minimizing of paper mill sludge process, stabilisation and innoxious.
Other disposal options is mainly burned, mix mud of heating up water, mix Beijing enamel brick and brick, prepare agricultural fertilizer etc., and the disposing sludge of these modes costly, and does not have efficiency utilization sludge resource.
Summary of the invention
In order to overcome the defect that prior art exists, the object of the invention is to, provide a kind of use the mud of regenerated papermaking to produce fluting medium and production method, reduce wastepaper as raw material consumption, the discharge capacity of minimizing solid waste.
In order to solve the problem, the invention provides a kind of fluting medium using regenerated papermaking mud to produce on the one hand, be that raw material is produced in the process of fluting medium with waste paper, in paper machine stock tank, adding the primary sludge of paper pulp fiber quality 0.5% ~ 2%; The biochemical sludge of paper pulp fiber quality 0.5% ~ 1%; The cationic starch of paper pulp fiber quality 0.1% ~ 1%; The cationic polyacrylamide of paper pulp fiber quality 0.01% ~ 0.08%; Mix; Through online manufacture paper with pulp, front drying, carry out top sizing, rear drying with surface sizing starch after obtain; The consumption of surface sizing starch be primary sludge, 0.2 ~ 1 times of biochemical sludge total amount.
On the other hand, the invention provides a kind of production method using regenerated papermaking mud to produce fluting medium, comprise the following steps:
Be in the process of raw material production fluting medium with waste paper, in paper machine stock tank, add the primary sludge of paper pulp fiber quality 0.5% ~ 2%; The biochemical sludge of paper pulp fiber quality 0.5% ~ 1%; The cationic starch of paper pulp fiber quality 0.1% ~ 1%; The cationic polyacrylamide of paper pulp fiber quality 0.01% ~ 0.08%; Mix;
Online is manufactured paper with pulp, and front drying, carries out top sizing, rear drying with surface sizing starch; The consumption of surface sizing starch be primary sludge, 0.2 ~ 1 times of biochemical sludge total amount.
As optimal technical scheme, use regenerated papermaking mud provided by the invention produces the production method of fluting medium, and described surface sizing starch is cornstarch or wood administration starch.
As further improvement opportunity scheme, use regenerated papermaking mud provided by the invention produces the production method of fluting medium, also adds the bentonite of cationic polyacrylamide 3.6wt% in paper machine stock tank.Adopt binary retention aid system, both combinations have more excellent technique effect, and the retention of regenerated papermaking mud is improved.
In the present invention, primary sludge refers to be the production line of raw material Production and Packaging paper and paperboard with waste paper, the mud that in sewage disposal process, preliminary sedimentation tank produces, biochemical sludge is in this sewage disposal process after Aerobic Process for Treatment, the system spare mud that secondary sedimentation tank and advanced treating precipitate.Paper pulp fiber, proportioning between primary sludge and biochemical sludge calculate by their absolute dry mass.
Technical scheme provided by the invention, carries out top sizing with surface sizing starch and can overcome the weak defect of the adhesion of inorganic matter because regenerated papermaking mud contains and fiber, thus improve into paper physical strength; Add cationic starch in the slurry, can in and regenerated papermaking Sludge Surface with higher negative electrical charge, and trapping negative ions rubbish, eliminates the interference that mud is used for wet end of machine in paper-making process; Add cationic polyacrylamide in slurry, the retention of mud and the mixed slurry water filtering performance at wet end of machine can be improved; High temperature when utilizing dry in Drying Process completes bactericidal action.Regenerated papermaking mud is used for production of fluting base paper, can reduce wastepaper as raw material consumption, reduces production cost, has good economic benefit; The generation of solid waste can be greatly reduced simultaneously, reduce pollutant end processing cost, there is significant environmental benefit.
Regenerated papermaking mud is usually containing a large amount of inorganic matters, and the adhesion of inorganic particulate and fiber is weak, and hinders the combination between fiber, and therefore, mud can affect into paper physical strength for the production of fluting medium.Add the mud of different amount as shown in Figure 1, mud reuse ratio is to the experimental result becoming paper fracture length: along with mud reuse ratio increases, the fracture length of fluting medium linearly declines, and mud reuse amount often increases by 1%, becomes paper fracture length to decline about 1%.
For keeping the quality of product to reach requirement, inventor, after test failure many times, selects and adopts starch to carry out top sizing.Top sizing amount is on becoming the impact of paper fracture length as shown in Figure 2.
Result of the test shows, adds the primary sludge of paper pulp fiber quality 0.5% ~ 2% in paper machine stock tank; The biochemical sludge of paper pulp fiber quality 0.5% ~ 1%; The cationic starch of paper pulp fiber quality 0.1% ~ 1%; The cationic polyacrylamide of paper pulp fiber quality 0.01% ~ 0.08%; Have and preferably become paper physical strength, have preferably mud retention simultaneously, the anion avoiding mud too much is manufactured paper with pulp on paper machine the impact of system.Carry out top sizing with the surface sizing starch of 0.2 ~ 1 times of mud total amount, the paper strength brought because adding mud can be made up and decline.
