EDTMPS EDTMPS (Ethylene Diamine Tetra (Methylene Phosphonic Acid) Sodium) ((EDTMPA, EDTMP, EDTMPS) CAS No. 1429-50-1 EDTMPS is nitrogenous organic polyphosphonic acid, a part of cathodic corrosion corrosion inhibition is 3~5 times better than that of inorganic polyphosphate. It can be fully dissolved in water, innocuous and none pollution to environment, has good chemical stability and thermal tolerance. It shows excellent scale inhibition ability under temperature 200centigrade. It can dissociate into 8 positive-negative ions, thus can chelate with many metal ions to form polymer reticulation complex, to destroy the normal crystallization of calcium scale. EDTMPS shows better antiscale effects to calcium sulfate and barium sulfate. Specification: Appearance : Clear yellow to umber transparent liquid Active component (EDTMPS): 30.0 % min Organic phosphonic acid (asPO43- ): 10.0% min Phosphorous acid (as PO33-): 5.0% max Phosphoric acid (asPO43- ): 1.0% max pH (1% water solution): 9.5-10.5 Density (20centigrade): 1.25 g/cm3 min Chloride (as Cl-): 3.0% max Usage: EDTMPS can be used as corrosion inhibitor in circulating cool water system and boiler water. It is a chelating agent in non-cyanogen electroplating industry and a water-softening agent in printing & dyeing industry. When used alone, 2~10mg/L is preferred. When built with HPMA by ratio ETDMP:HPMA=1:3, it can be used for low pressure boiler. It can also be built with BTA, PAAS and zinc salt. Package and Storage: Normally In 250kg net Plastic Drum, IBC drum can also be used as required. Storage for ten months in room shady and dry place. HEDP HEDP (1-Hydroxy Ethylidene-1, 1-Diphosphonic Acid) (HEDP, , *****2, *****4, HEDP.Kx) CAS No. 2809-21-4 HEDP is an organophosphoric acid corrosion inhibitor. It can chelate with Fe, Cu, and Zn ions to form stable chelating ***** can dissolve the oxidized materials on these metalsâ�¯�¿�½�¯�¿�½ surfaces. HEDP shows excellent scale and corrosion inhibition effects under temperature 250centigrade. HEDP has good chemical stability under high pH value, hard to be hydrolyzed, and hard to be decomposed under ordinary light and heat conditions. Its acid/alkali and chlorine oxidation tolerance are better than that of other organophosphoric acids (salt). HEDP can react with metal ions in water system to form hexa-element chelating complex, with calcium ion in particular. Therefore, HEDP has good antiscale and visible threshold effects. When built together with other water treatment chemicals, it shows good synergistic effects. The solid state of HEDP is crystal powder, suitable for usage in winter and freezing districts. Because of its high purity, it can be used as cleaning agent in electronic fields and as additives in daily chemicals. Specification: Appearance: Colorless or light yellow transparent liquid White crystal powder Active content (HEDP): 58.0-62.0% 89.0 % min Phosphorous acid (as PO33-): 2.0 % max 0.5 % max Phosphoric acid (asPO43- ): 0.8 % max 0.5% max Chloride (as Cl-): 0.01 % max 0.01 % max pH (1ï¼�¯�¿�½ solution): 2 max 2 max Density (20centigrade): 1.40 g/cm3 - Fe ion ppm: 10 max 20 max Colour APHA (Hazen): 40 max - Usage: HEDP is used as scale and corrosion inhibition in circulating cool water system, oil field and low-pressure boilers in fields such as electric power, chemical industry, metallurgy, fertilizer, In light woven industry, HEDP is used as detergent for metal and nonmetal. In dyeing industry, HEDP is used as peroxide stabilizer and dye-fixing agent; In non-cyanide electroplatin HPAA HPAA (2-Hydroxyphosphonocarboxylic Acid) ( HPAA, HPMA, HEDP) CAS No 23783-26-8 Properties: HPAA is chemically stable, hard to be hydrolyzed, hard to be destroyed by acid or alkali, safety in use, no toxicity, no pollution. HPAA can improve zinc solubility. Its corrosion inhibition ability is 5-8 times better than that of HEDP and EDTMP. When built with low molecular polymers, its corrosion inhibition effect is even better. Specification: Appearance: Dark umber transparent viscous liquid Solid content : 47.0-50.0% Phosphorous acid(as PO33-): 4.0 % max Density (20centigrade): 1.30 g/cm3 min pH(1% solution) : 1.0-3.0 Usage: HPAA is mainly used as cathode corrosion inhibitor in oilfield refill water system in fields such as steel & iron, petrochemcal, power plant and medical industries. When built with zinc salt, the effect is even better. Package and Storage: Normally In 250kg net Plastic Drum, IBC drum can also be used as required. Storage for one year in room shady and dry place.
