The best dosage of polymer dispersant in WDG by Zata potential method

摘要

Applied self-prepared GY dispersant into 75% thifensulfuron WDG formulation,only chang the dispersant and filler content, found out the optimal amount of dispersant using zata potential analyzer. The results show that when the dosage of dispersant is 6%, zeta potential to achieve the most negative,75% tribenuron water dispersible granule apparent suspension rate of more than 90%. Zata potentiometric method is a rapid method that decide anionic dispersant dosage.
