Superiority

1, the optimum ph of akd wax sizing is 7.5-8.5 - a neutral condition, which is more environmental friendly than rosin (acidic sizing agent). so akd wax has been gradually replacing rosin.

2, akd sizing can improve the strength and whiteness of paper, and can keep the good effect for a long time.

3, alkaline filler can be added for paper making, such as: calcium carbonate.

4, as neutral sizing, it is has less corrosion to machine and alkaline filler can be added for paper making, such as: calcium carbonate.

product name: alkyl ketene dimer 1840

synonyms: akd wax 1840; alkylketene dimer 1840; akd 1840

cas no: 144245-85-2

chemical formula: c_nh_2n-4o₂

structural formula:

r –ch=c–o

¦ ¦

r–hc–c=o

(r= alkyl chain)

appearance: pale yellow tablet.

akd wax is obtained from higher fatty acids (c>12) which is via acylation and dehydrochlorination.

so this product has excellent water resistance performance as the alkyl chain of higher fatty acids.

as a basic sizing agent, akd was has been widely used in paper-making industry as emulsion.

by now, akd wax can be used as pulp sizing and surface sizing to many kinds of paper, such as cultural paper, paperboard, newsprint paper, board, fruit bag paper and wrapping paper.
