Paper Making Additive Alkyl Ketene Dimer AKD Emulsion Soak
Capability Of Acid Alkaline Liquor
Description:
1.AKD emulsion is one of the reactive neutral sizing agents, it can
be used in the process of neutral paper making in factories
directly. 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.
2.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.
3.This product is obtained from higher fatty acids (C>12) which is via acylation and dehydrochlorination.Liquid AKD emulsion is emulsified from solid AKD wax together with
the cationic auxiliaries,widely used as the neutral sizing agent in papermaking industry.

Features:
1.It can effectively increase the surface strength and improve the
printability of paper.
2. It can reduce the phenomenon of dropping fiber and powder.
3. It could be used to adjust the sizing degree quickly and improve
the water resistance of the paper
4. It does not have negative effect on people's health in the
process of shipping, storing and using.
5. It can reduce the pressure of water treatment, and reduce cost
of production.
6. Well compatibility, it is compatible with CMC, PVA, starch and
so on.
7. Curing speed is high.
8. Suitable for all kinds of surface sizing equipment.
Usage method:
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.
