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

    Le HEDP-Na4 est le sel de sodium du HEDP. C'est un excellent inhibiteur de tartre et de corrosion pour le carbonate de calcium. Le HEDP-Na4 est principalement utilis\u00e9 dans le traitement de l'eau des chaudi\u00e8res \u00e0 basse pression, le traitement de l'eau de circulation, l'eau propre industrielle et municipale et la d\u00e9sinfection des piscines pour la pr\u00e9vention de la corrosion des m\u00e9taux.<\/p>\n

    Le HEDP-Na4 est une poudre blanche facilement soluble dans l'eau. Il est facile \u00e0 transporter et convient \u00e0 une utilisation dans des conditions de froid extr\u00eame. Il peut former des complexes stables avec divers ions m\u00e9talliques tels que le fer, le cuivre et le zinc, et peut dissoudre les oxydes \u00e0 la surface des m\u00e9taux. C'est un stabilisateur de la qualit\u00e9 de l'eau alcaline.<\/p>\n

    1. Champ d'application et m\u00e9thodes d'utilisation<\/li>\n<\/ol>\n

      L'inhibiteur de tartre HEDP-Na4 est largement utilis\u00e9 dans l'eau de refroidissement industrielle circulant dans les industries de l'\u00e9nergie, de la chimie, de la m\u00e9tallurgie et des engrais, ainsi que dans les chaudi\u00e8res \u00e0 basse pression et dans l'eau de r\u00e9injection des champs p\u00e9trolif\u00e8res pour l'inhibition du tartre et la pr\u00e9vention de la corrosion. Dans l'industrie textile, il peut \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 l'impression et de la teinture, comme agent complexant sans cyanure pour la galvanoplastie et comme additif pour les produits chimiques quotidiens.<\/p>\n

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

        L'inhibiteur de tartre liquide HEDP-Na4 est conditionn\u00e9 dans des f\u00fbts en plastique, chaque f\u00fbt contenant 30 kg ou 250 kg. Le HEDP-Na4 solide est emball\u00e9 dans des sacs en plastique tiss\u00e9s doubl\u00e9s de sacs en poly\u00e9thyl\u00e8ne, chaque sac pesant 25 kg net. La quantit\u00e9 peut \u00eatre d\u00e9termin\u00e9e en fonction des besoins de l'utilisateur. Le produit doit \u00eatre stock\u00e9 \u00e0 l'int\u00e9rieur, dans un endroit frais et sec. La dur\u00e9e de conservation est de dix mois.<\/p>\n

        1. Protection de la s\u00e9curit\u00e9<\/li>\n<\/ol>\n

          Le HEDP-Na4 est alcalin. Il faut \u00e9viter tout contact avec la peau, les yeux, etc. En cas de contact, rincer abondamment \u00e0 l'eau.<\/p>","protected":false},"excerpt":{"rendered":"
