Methods for inhibiting barium sulfate deposition using a poly(amine)compound or its salts in papermaking systems |
摘要 |
The present invention provides for methods of inhibiting the formation and deposition of barium sulfate on the surfaces of papermaking systems. The inventive treatments comprise adding an effective amount of a poly(amine) compound to the papermaking systems. Representative polymers include polyallylamine, polytrimethylallylammonium chloride and polyvinylamine.
