METHOD AND USE FOR ADJUSTING OF ZETA POTENTIAL OF FIBRE STOCK

The invention relates to a use and a method for adjusting of zeta potential of an aqueous fibre stock in manufacture of paper, board, tissue of the like, where an anionic lignin-carbohydrate complex, where lignin and carbohydrate are covalently bound with each other, is introduced to the fibre stock...

Zusammenfassung:	The invention relates to a use and a method for adjusting of zeta potential of an aqueous fibre stock in manufacture of paper, board, tissue of the like, where an anionic lignin-carbohydrate complex, where lignin and carbohydrate are covalently bound with each other, is introduced to the fibre stock. L'invention concerne une utilisation et un procédé de réglage du potentiel zêta d'une composition à base de fibres non aqueuses dans la fabrication de papier, de carton, de tissu ou similaire, un complexe lignine-glucide anionique, dans lequel la lignine et le glucide sont liés de manière covalente l'un à l'autre, étant introduit dans la composition à base de fibres.
