Addition amount and usage method
Please test the optimal dosage for a total amount of 0.05-3.0%; After addition, it should be mixed under sufficiently high shear force. It is recommended to add before grinding.
The accurate amount and usage method may vary depending on the specific situation and should be determined through experiments.
