  1. Performance des produits<\/li>\n<\/ol>\n

    Ce produit est un inhibiteur de calcaire et de corrosion de type phosphonate organique. Il peut former des complexes stables avec divers ions m\u00e9talliques tels que le fer, le cuivre et le zinc. C'est un agent ch\u00e9lateur stable qui peut dissoudre les oxydes \u00e0 la surface du m\u00e9tal et qui n'est pas sujet \u00e0 l'hydrolyse. Il n'est g\u00e9n\u00e9ralement pas d\u00e9compos\u00e9 \u00e0 la lumi\u00e8re et \u00e0 la chaleur. Sa r\u00e9sistance aux acides et aux alcalis et sa r\u00e9sistance \u00e0 l'oxydation du chlore sont meilleures que celles des autres phosphonates (sels) organiques.<\/p>\n

    1. Champ d'application et m\u00e9thode d'utilisation<\/li>\n<\/ol>\n

      Il est largement utilis\u00e9 dans les syst\u00e8mes industriels de circulation d'eau de refroidissement d'industries telles que l'\u00e9nergie, l'ing\u00e9nierie chimique, la m\u00e9tallurgie et la production d'engrais, ainsi que dans les chaudi\u00e8res \u00e0 moyenne et basse pression et dans l'eau d'injection des champs p\u00e9trolif\u00e8res pour l'inhibition de l'entartrage et la pr\u00e9vention de la corrosion. Dans l'industrie du textile l\u00e9ger et de l'impression et de la teinture, il est utilis\u00e9 comme dispersant \u00e0 complexe ionique. Il peut \u00e9galement \u00eatre utilis\u00e9 comme agent de nettoyage pour les m\u00e9taux et les non-m\u00e9taux, comme stabilisateur de peroxyde et fixateur de couleur dans l'industrie de la teinture, et comme agent d'eau douce dans l'industrie cosm\u00e9tique. Il est \u00e9galement utilis\u00e9 comme agent complexant dans l'industrie de la galvanoplastie sans cyanure.<\/p>\n

      1. Emballage et stockage<\/li>\n<\/ol>\n

        Le HEDP-Na2 liquide est conditionn\u00e9 dans des f\u00fbts en plastique, chaque f\u00fbt contenant 30 kg ou 250 kg. Le HEDP-Na2 solide est conditionn\u00e9 dans des sacs en plastique tiss\u00e9s, doubl\u00e9s de sacs en poly\u00e9thyl\u00e8ne, chaque sac pesant 25 kg. L'emballage exact peut \u00eatre d\u00e9termin\u00e9 en fonction des besoins de l'utilisateur. Le produit doit \u00eatre stock\u00e9 dans un endroit frais, \u00e0 l'int\u00e9rieur. La dur\u00e9e de conservation est de dix mois.<\/p>\n
