Prod­uct performance

ASA has a high­er reac­tiv­i­ty than AKD and is very easy to form ester bonds with the hydrox­yl groups on the fiber sur­face. Of course, ASA is also very easy to hydrolyze to form diba­sic acids when it encoun­ters water. If ASA is used improp­er­ly, a large amount of hydrol­y­sis prod­ucts will seri­ous­ly affect the oper­a­tion of the paper machine. The cost of ASA siz­ing is low­er than that of tra­di­tion­al AKD siz­ing, but the use require­ments are rel­a­tive­ly harsh. How to use ASA well has always been a dif­fi­cult prob­lem for cur­rent paper­mak­ers. The above data is expect­ed to pro­vide a cer­tain ref­er­ence for the major­i­ty of papermakers.

Known Appli­ca­tion

As a siz­ing agent, it is com­mon­ly used in the paper­mak­ing industry.
