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 apermaking industry.
It is in AKD neutral-alkaline sizing system,greatly limiting the AKD hydrolysis and migration tendencies.On the other hand,due to AKD sizing has curing time,so after add in this high cationic polymer product,AKD curing decrease to be about 8 hours,usually after rewinding,AKD sizing can realize 80% above.It is also called AKD promoter or AKD sizing enhancing agent.
AKD high polymer emulsifier (instead of traditional cationic starch based) is a kind of cationic polymer product developed by our technical department,which is the initiative developed product in the market.It can not only emulsify AKD wax,but also proteched the AKD colloid dispersion and aid retention,it also can increase AKD sizing efficiency(2%-8%).
According to C18 content, it has AKD WAX 1840, AKD WAX 1865, AKD WAX 1895.Based on our own phosgene project,using top grade stearic acid, auto production under DCS control, all these make sure our final AKD WAX quality is the top grade, purity can be 91%min.We not only consider on supplying AKD WAX,but also consider more on technology support and recipe improvement sharing.
Anionic surface sizing agent is a new type od surface sizing agent that synthesized by the copolymerization of styrene and ester.It can efficiently combinate with starch result good cross link intensity and hydrophobic properties.With lower dosage,low cost and easy use advantages,it has good film-forming property which can significantly improve the water-resistance and ring-crush strength of writing and printing paper,such as offset printing paper and electro-photographic paper.
