Alkyl Ketene Dimer Emulsion , AKD netural Emulsion for paper sizing
|Appearance||Milk white emulsion|
|viscosity, mPa.s, 25℃, max.||10||15||20|
AKD emulsion is one of the reactive neutral sizing agents, it can
be used in the process of neutral paper making in factories
Paper can not only be endowed with predominant capability of water
resistance, and soak capability of acid alkaline liquor, but also
with ability of brim soaking resistance.
By using it can improve physical properties of paper, it has been
widely used in producing various kind of paper, such as art base
paper, electrostatic autographic transfer paper, double colloid
paper, noncarbon paper, archival paper, photo base paper, yew base
paper, stamp base paper, napkin, etc.
The product can be directly add to the thick pulp, or add to the
mixing chest after diluted. And it can also be tub-sized after the
former paper dried. The added amount should be 0.1%-0.2% of
absolute dry pulp for normal sizing, 0.3%-0.4% for heavy sizing.
Double resident system of cation starch and polyacrylamide should
be coupled with at the same time. The cation starch should be
quaternary ammonium type, its substitute degree is more than 0.025%
and its usage should be 0.6%-1.2% of absolute dry pulp. The
molecular weight of polyacrylamide is 3,000,000-5,000,000, its
concentration is 0.05%-0.1% and its usage should be100ppm-300ppm.
The PH of pulp is 8.0-8.5.
Packed in plastic drum, 200 Kg or 1000Kg each, or 23tons/flexibag.
This product should be stored in a dry warehouse, protected from
frost and direct sunlight. Storage temperature should be 4- 30℃.
