Description
Technical field
The present invention relates to pulping and paper-making production technical field, substitute OCC slurry particularly to a kind of brush wood wood chip defibrator process slurry
Join the production method copying high-grade cardboard.
Background technology
In recent years, it is with waste and old boxboard as raw material that grey board produces conventional art, prepares OCC slurry through OCC Pulping Line
As grey board lining, sandwich layer, base pastes；With old newspaper as raw material, prepare ONP slurry through ONP line and starch as grey board fine dried noodles.
Its leading indicator thickness of grey board that this technique produces is on the low side, and when the reason such as fluctuation of raw material causes thickness fluctuation, does not has
Effective means carries out thickness adjusted in time, and product quality does not often reach requirement, limits the use of product.Some production lines in
Being mixed into sawmilling powder in OCC Pulping Line wastepaper as raw material, sawdust purifies online in company with OCC line manufacture paper with pulp, to reaching through size degradation, screening
The thickness indication required, in actual production, sawdust runs off big, and the improvement to thickness is limited, and the grey board deflection manufactured paper with pulp is low, with
Sample limits the use of product.
During realizing the present invention, inventor finds that in prior art, there are the following problems:
1, the grey board thickness that conventional art is manufactured paper with pulp is low, does not often reach thickness indication requirement.
2, thickness fluctuation is done adjustment in time by conventional art shortage effective means, and produced grey board thickness fluctuation is big, limit
The use of product processed.
3, the grey board deflection that conventional art is manufactured paper with pulp is relatively low, and product specification is low, limits the use of product.
4, conventional art is because the restriction of thickness, and wastepaper as raw material prescription is high, and OCC waste paper unit consumption is big, and production cost is high.
5, conventional art is because thickness, the restriction of deflection, and the ash of body paper controls relatively low, and production cost is high.
Summary of the invention
For this reason, it may be necessary to provide a kind of brush wood wood chip defibrator process slurry to substitute OCC slurry join the production method copying high-grade cardboard, it is used for
Solve the problem that grey board thickness is low, thickness is unstable, deflection is low.
For achieving the above object, inventor provide a kind of brush wood wood chip defibrator process slurry to substitute OCC slurry and join and copy high-grade cardboard
Production method, comprise the following steps:
