Description
Technical field
The present invention relates to paper-making technology field more particularly to a kind of composite starch and its system for top sizing
Preparation Method.
Background technique
Wrapping paper is primarily used for the general designation of a kind of paper of packaging purpose, usually has high intensity and toughness, is resistant to
Pressure, folding, quality requirement are simpler than paper kinds such as cultural printings, need in wrapping paper manufacturing process using size-press starch pair
The coating of its surface, to increase its physical property, complies with requirement.
The surface sizing starch that factory uses at present substantially has a two major classes, one kind be conventional corn ative starch through peroxidating,
The forms such as enzymatic conversion dilute use after boiling, and cost is relatively low for this kind of sizing, but starch lot stability is poor, glue is easy always
Change, starch has been easy in Process of Applying Glue and has wadded a quilt with cotton poly- phenomenon to which sizing applicator glues rod, has caused shadow to paper machine operation and quality of finished paper
It rings, in addition a kind of oxidized starch for after traditional hypochlorite oxidation, this kind of starch causes to give birth to due to processing technology complexity
Higher cost is produced, in addition, the waste water that starch systems cleaning generates contains oxidant and can cause unfavorable shadow to later period sewage treatment
It rings, therefore, the composite starch and preparation method thereof that we have proposed a kind of for top sizing.

2) aluminium salt, emulsifier and dispersing agent, agitator speed are then added into blender and are adjusted to 500rpm, until forming sediment
After powder dispersion completely, scattered starch suspension is sent by the filter of 50-80 mesh to the storagetank storage of belt stirrer
It deposits, storagetank blender keeps the revolving speed of 50rpm；
3) delivery pump in scattered starch suspension by being delivered in continuous steamer in storagetank, in boiling vessel
It is passed through the steam of high temperature and pressure, starch fluid makes the rapid water swelling of starch, division, paste by transient heating, high temperature difference and pressure
Change, storagetank storage is sent into after the heated water on-line dilution to predetermined solid content of gelatinized corn starch after boiling, gelatinization point control exists
125 DEG C, the temperature of paste liquid storagetank is controlled at 60 DEG C or more, is led to steam insulation using collet slot, is kept stirring speed 30-
40rpm。
In conclusion compared with the prior art, the invention has the following beneficial effects:
