Abstract

Det beskrives en fremgangsmåte og ect materiale for avsverting av returpapir. Fremgangsmåten omfatter å administrere en alkohol, vilkårlig alkosylert med en blanding av alkylenoksider for å danne en surfaktant, til en prøve av returpapir for hvilken behandling er ønskelig. Surfaktanten forbedrer aggregeringen og fortettingen av elektrostatiske tonerpartikler idet den frerrjuer skumming i den vandige oppslemming.
