Detailed Product Description: | Hydroxy-1 ,1-diphosphonic acid disodium HEDP? Na2 Changzhou hydroxy-1 ,1-diphosphonic acid disodium HEDP? Na2 First, the performance and use HEDP · Na2 is an organic phosphonic acid scale inhibitor, with iron, copper, zinc and other metal ions form stable complexes, can dissolve the metal oxide surface. HEDP · Na2 at 250 ℃ can still play a good scale and corrosion inhibition effect at high pH remains stable, not easily hydrolyzed, usually difficult to decompose under the conditions of light and heat. Acid, and chlorine oxidation tolerance than other organic acid (salt). With water, metal ions, especially calcium ions to form six chelate ring, thus a good scale inhibition and a visible threshold effects, when combined with other water treatment chemicals used, showing the good synergies . HEDP · Na2 is widely used in electric power, chemical industry, metallurgy, fertilizers and other industrial cooling water systems and in low-pressure boiler, oil field water pipelines as scale and corrosion inhibition; HEDP · Na2 in the textile industry, can be used for metal and non- metal cleaning agent, bleaching and dyeing industry as peroxide stabilizer and dye-fixing agent, complexing agent cyanide-free electroplating industry. Second, the technical indicators Third, the use of Generally used for the concentration of inhibitor 2 ~ 20mg / L, for the general use of inhibitor concentrations 20-100mg / L, for general use cleaning agent concentration 1000 ~ 2000mg / L, often with polycarboxylate type scale with the use of dispersants . Fourth, packaging and storage HEDP · Na2 liquid plastic barrel, 30kg or 250kg, HEDP · Na2 solid polyethylene bags lined plastic woven bag, net weight 25kg, can also be used as required. Stored in a cool room, storage for 12 months solid, liquid storage period of ten months. Fifth, security HEDP · Na2 as a weak acid, when attention to labor protection and should avoid contact with skin, eyes and other contact, flush with plenty of water after contact.
