2.Selection
AN923C is suitable for paper(wood pulp)(18g/m2 or less),Dissolved time (MIN) is one hour, linear speed of paddle 2£4m/s.
AN926C is suitable for paper (waste paper)(18g/m2£25g/ m2)Dissolved time (MIN) is 2 hours, linear speed of paddle 4£6m/s.
Retention and filtration aid
Polymer with large MW can help Retention and Polymer with small MW can help filtration
Reinforced agent
it can improve strength and Properties of pape
