Performance and use:

       HEDP·Na2 is a kind of organic phosphonic acid scale inhibitor and corrosion inhibitor, which can form stable complexes with iron, copper, zinc and other metal ions, and can dissolve oxides on the metal surface。HEDP·Na2 can still play a good corrosion and scale inhibition effect at 250℃, is still very stable at high pH value, is not easy to hydrolysis, and is not easy to decompose under general photothermal conditions。Acid and alkali resistance, chlorine oxidation resistance than other organic phosphoric acid (salt) better。It can form a six-ring chelate with metal ions in water, especially calcium ions, so it has a good scale inhibition effect and a significant solution-limiting effect, when and othersWater treatmentThe ideal synergistic effect was shown when the compound was used。

       HEDP·Na2 is widely used in power, chemical, metallurgy, fertilizer and other industrial circulating cooling water system, medium and low pressure boiler, oil field water injection and oil pipeline scale inhibition and corrosion inhibition;HEDP·Na2 in the textile industry，It can be used as a cleaning agent for metals and non-metals，Peroxide stabilizer and color fixing agent for bleaching and dyeing industry，Complexing agent for cyanide-free electroplating industry。

How to use:

       作为Antiscale agentThe general use concentration is 2~20mg/L, the general use concentration of corrosion inhibitor is 20-100mg /L, and the general use concentration of 1000~2000mg/L as a cleaning agent is usually used in combination with polycarboxylic acid scale inhibitor and dispersant。

Packing and storage:

       HEDP·Na2 liquids are packed in plastic drums, 30kg or 250kg per barrel, and HEDP·Na2 solids are packed in plastic woven bags lined with polyethylene bags, with a net weight of 25kg per bag, which can also be determined according to user needs。Store in a cool place indoors for 10 months。

Safety and Protection:

       HEDP·Na2 is weakly acidic, should avoid contact with eyes, skin, once splashed on the body, should immediately rinse with plenty of water。
