Abstract

L'invention concerne une composition et un procédé pour inhiber les incrustations sur les surfaces en contact avec l'eau. Lorsqu'on ajoute à de l'eau de chaudière un copolymère d'acide styrènesulfonique et d'anhydride ou d'acide maléique et un acide organphosphonique en particulier l'acide hydroxy-1 éthylidène-diphosphonique- 1,1, cette combinaison d'additifs inhibe la formation des incrustations plus efficacement qu'une même concentration de l'un ou l'autre de ces additifs. L'invention peut être utilisée pour prolonger la durée de service des chaudières.The invention relates to a composition and a method for inhibiting encrustation on surfaces in contact with water. When a copolymer of styrenesulfonic acid and anhydride or maleic acid and an organphosphonic acid, in particular 1-hydroxyethylidene-diphosphonic acid-1,1, is added to boiler water, this combination of additives inhibit the formation of encrustation more effectively than the same concentration of either of these additives. The invention can be used to extend the service life of boilers.
