Description
Technical field
The invention belongs to paper products processing technique field, specifically, a kind of papermaking process for improving paper quality.
Background technology
Paper products ash content is the inorganic matter in paper products, generally comprised added in paper industry production process can not
The compound of combustion（Such as papermaking filler）And the noncombustible matter in paper pulp.Ash content in paper products（Especially papermaking filler）Than
The increase of weight can substantially reduce the cost of papermaking.
CN101736656A provides a kind of papermaking process with increased filer content, and methods described includes following step
Suddenly：The blend composition of filler particles, at least one strength additive and cellulose fibre raw material is provided, institute is handled with material compositions
Filler particles are stated, the filler particles is mixed with the cellulose fibre raw material, handle mixed with least one strength additive
Compound, and cardboard is formed by the mixture, wherein at least the 10% of the filler particles is winnofil and described fills out
It is grinding calcium carbonate to expect at least the 10% of particle, and the cellulose fibre raw material includes multiple fiber cellulose fiber and water, and described
Material compositions enhance the performance of the strength additive in the cardboard.
If pursuing the increase of paper products ash content simply to reduce papermaking cost, the quality of gained paper products can be influenceed.
For example：Papermaking dry-strengthening agent has the tendency of coating papermaking filler particle, thus the more fillers of addition can reduce the effect of drying strengthening agent
Rate.The filler particles existed are more, just have more drying strengthening agent coating filler particles, and therefore just have fewer drying strengthening agent
It can be used to combine cellulose fibre.
Therefore, market needs a kind of quality that can increase paper products ash content and not lose gained paper products, reduces simultaneously
A kind of papermaking process and its paper products of the production cost of gained paper products.
The content of the invention
, should it is an object of the invention to provide a kind of papermaking process for improving paper quality for defect of the prior art
Method can increase paper products ash content and not lose the quality of gained paper products, while reducing the production cost of gained paper products.
A kind of papermaking process of the raising paper quality provided according to an aspect of the present invention, the raising paper quality is made
Paper method is specially：
Step one：The interior starch addition mill disposed slurry that adds is sent into the pipeline of slurry tower, is being 45%- into slurry tower slurry liquid level
When 50%, using into the agitator in slurry tower by it is interior add starch and mill disposed slurry be thoroughly mixed it is uniform, then into
Starch and flocculant is added in tower, above-mentioned compound stirs using into the agitator in slurry tower, the first mixed slurry, institute is formed
The first mixed slurry granularity is stated in the range of 10-150 μm；
Step 2：Filling modifier is added in the packing pump porch in filler working tank exit, the filling modifier includes
