Abstract

Det er beskrevet en fremgangsmåte for fremstilling av mekanisk eller kjemimekanisk masse som råmateriale for papir og papp. l henhold til denne fremgangsmåten blir massen fibrillert og den fibrillerte massen blir bleket under alkaliske betingelser. I henhold til foreliggende oppfinnelse blir massen silt for å separere rejektet fra akseptet, og maksimalt 60 % av den totale mengden masse blir separert som rejekt. Rejektet blir bleket adskilt fra akseptet og deretter blir det blekede rejektet blandet igjen med akseptet. Ved å operere i henhold til foreliggende oppfinnelse, øker styrken til massen og energien som brukes for raffinering blir redusert, noe som sees både ved raffineringen og i etterraffineringen av den endelige mekaniske massen.
