Abstract
Pour blanchir des pâtes de cellulose et d'autres substances fibreuses dans le cadre de la fabrication de papier, on introduit du peroxyde d'hydrogène ou des composés séparant le peroxyde dans des solutions alcalines. Les peroxydes sont décomposés de manière homolytique par les ions de métal de transition contenus en faibles concentrations dans les substances fibreuses cellulosiques, ce qui entraîne des pertes considérables en peroxyde, ainsi que la dissociation de chaînes d'hydrates de carbone, due à la réactivité des radicaux d'oxygène. Selon ce procédé, pour stabiliser des solutions de blanchiment alcalines contenant de l'oxygène, du peroxyde d'hydrogène et/ou des composés séparant le peroxyde, sans pression ou sous pression hydrostatique pour blanchir des suspensions aqueuses de substances fibreuses, dans le cadre de la fabrication de papier ou dans le traitement ultérieur de substances fibreuses utilisées dans l'industrie chimique (pâtes dissolvantes), on utilise comme agent de stabilisation, isolément ou sous forme de mélange, une combinaison de l'agent complexant de type 1, comprenant du phosphonate et/ou de l'acide poly-α-hydroxyacrylique et/ou de l'acide aminopolycarboxylique, conjointement avec l'agent complexant de type 2, comprenant des composés oxy ou polyoxy ayant entre 2 et 7 atomes de C dans la chaîne de carbone et/ou des dérivés protéiques. Le mélange de stabilisation permet d'obtenir d'excellents degrés de blanc avec une consommation considérable de peroxyde d'hydrogène. Par ailleurs, pendant le processus de blanchiment, les fibres sont nettement moins altérées et le mélange de stabilisation présente une meilleure biodégradabilité que l'agent complexant de type 1.
