Abstract:Polyvinylamine is a new chemical in paper industry. It can be cationic or amphoteric depending on the synthetical process. This paper mainly introduced the application of amphoteric polyvinylamine in non-wood paper production. Production results indicated that it could improve the wet web dryness therefore increase initial wet web strength. Polyvinylamine could improve machine efficiency, optimize raw material and save energy and so on. Finally, it could reduce the total cost of operation.
