Abstract

L'invention concerne des inhibiteurs de corrosion et agents anti-tartre pour le traitement d'eaux. Il s'agit de mélanges d'additifs comprenant un acide phosphonocarboxylique, un polyphosphate hydrosoluble et un inhibiteur de corrosion non ferreux, avec en plus de l'anhydride polymaléique hydrolysé destiné à faciliter la dispersion du phosphate de calcium afin d'éviter la formation de boues de phosphate qui encrassent les échangeurs de chaleur, colmatent les filtres et crépines, diminuent l'efficacité des tours de refroidissement et reduisent l'action de l'inhibiteur de corrosion.
