HEDP?Na2 can form six-ring chelating compounds with metal ions in water system, Ca2+ in particular. HEDP Na2 has good scale inhibition effects and obvious dissolution threshold effects. When used with other Water Treatment Chemicals, the synergistic effects is better. Specification:Appearance:Colorless to light yellow transparent liquid;White powderActive component(HEDP)%:16.5 min;74.0-79.0Active component(HEDP Na2)%:20.0 min;89.8 mindensity(20 centigrade degrees)g/cm3:1.12-1.22;Fe ppm:;35 maxPhosphorous acid(PO33-)%:;3 maxDry weight loss，%:;3-6PH (1% water solution):4.0-6.0;4.0-6.0Usage:HEDP Na2 is widely used in circulating cool water system, medium and low pressure boiler, oil field water pipelines as scale and corrosion inhibitor in fields such as electric power, chemical industry, metallurgy, fertilizer, In light woven industry, HEDP?Na2 is used as detergent for metal and nonmetal. In dyeing industry, HEDP Na2 is used as peroxide stabilizer and dye-fixing agent; In non-cyanide electroplating, HEDP?Na2 is used as chelating agent. Package and Storage:For liquid: Normally In 250kg net Plastic Drum, IBC drum can also be used as required. Storage for ten months in room shady and dry place. For solid: inner liner polyethylene (PE) bag, outer plastic woven bag, or confirmed by clients. Storage for ten months in room shady and dry place. . Safety Protection:Weak acidity, Avoid contact with eye and skin, once contacted, flush with water.Sell 2-Phosphonobutane -1, 2, 4-Tricarboxylic Acid(PBTCA)CAS No. 37971-36-1Dequest:7000Molecular Formula:C7H11O9PMolecular weight: 270.13 Properties:PBTCA has low content of phosphoric, has structural features of both phosphoric acid and carboxylic acid group, which enable its excellent scale and corrosion inhibition properties. Its antiscale property under high temperature is far better than that of organophosphines. It can improve zinc salt solubility, has good chlorine oxidation tolerance and good composite synergy. Specification:Appearance:Colorless or light yellow transparent liquidActive acid %:50.0 minPhosphorous acid(as PO33-)%:0.8 maxPhosphorous acid(as PO43-)%:0.5 maxDensity(20 centigrade degrees)g/cm3:1.27 minpH(1% solution):1.5-2.0Usage:PBTCA is a high efficient agent as scale and corrosion inhibitor. It is the excellent stabilizer for zinc salt. It is widely used in circulating cool water system and oilfield refill water system as scale and corrosion inhibitor, suitable to composite with zinc salt and copolymer. It can be used in situations of high temperature, high hardness, high alkali and high concentration index. In lavation fields, it is used as chelating agent and metal detergent. PBTCA is usually used together with zinc salt, copolymer, organophosphine, imidazole and other Water Treatment Chemicals. When used alone, the dosage of 5-15mg/L is preferred.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. Safety Protection:Acidity, Avoid contact with eye and skin, once contacted, flush with water.Thank you for taking the time to go through our business profile.
