  1. 1.Product Performance<\/li>\n<\/ol>\n

    EDTMP\u2022Na5 is a nitrogen-containing organic polyphosphate. It is a cathodic type corrosion inhibitor and can be mixed with water. It is non-toxic and pollution-free, has good chemical stability and heat resistance. It still has a good scale inhibition effect at 200\u2103. This product has good scale inhibition effects on calcium sulfate and barium sulfate scales and can be used as a scale inhibitor for oilfield injection water.<\/p>\n

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

      EDTMP\u2022Na5 is used as a scale inhibitor and corrosion inhibitor for circulating water and boiler water, a complexing agent for cyanide-free electroplating, a chelating agent in the textile printing and dyeing industry, and an oxygen bleaching stabilizer. When added alone in the circulating cooling water, the general dosage is 5-10 mg\/L. When compounded with HPMA in a ratio of 1:3, it can be used for water treatment in low-pressure boilers. This product can also be used in combination with BTA, PAAS, zinc salts, etc.<\/p>\n

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

        EDTMP\u2022Na5 is packaged in plastic drums. Each drum contains 25 kg or as determined by the user. It should be stored in a cool, indoor place. The shelf life is ten months.<\/p>\n

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

          EDTMP\u2022Na5 is weakly alkaline. When using, labor protection equipment must be worn. Contact with skin and eyes should be avoided. Rinse with plenty of water immediately after contact.<\/p>","protected":false},"excerpt":{"rendered":"
