We are offering amino trimethylene phosphonic acid. molecular formula: n(ch2po3h2)3 molecular weight: 299.05structural formula: property:atmp has excellent chelation, low threshold inhibition and lattice distortion ability. It can prevent scale formation, calcium carbonate in particular, in water system. Atmp has good chemical stability and is hard to be hydrolyzed in water system. At high concentration, it has good corrosion inhibition. atmp is used in industrial circulating cool water system and oilfield water pipeline in fields of thermal power plant and oil refinery plant. Atmp can decrease scale formation and inhibit corrosion of metal equipment and pipeline. Atmp can be used as chelating agent in woven and dyeing industries and as metal surface treatment agent. the solid state of atmp is crystal powder, soluble in water, easily deliquescence, suitable for usage in winter and freezing districts. Because of its high purity, it can be used in woven & dyeing industries and as metal surface treatment agent. specifications:items indexappearance colorless or light yellow transparent liquid white crystal powderactive acid % 48.0-52.0 95 minchloride (as cl-)% 2.0(or1.0) min 1.0 minph value1 solution 2.0 max 2.0 maxfe (as fe3+) (ppm) 20 20density 20g/cm3 1.33 min colour apha (hazen) 40 max use:atmp is usually used together with organophosphoric acid, polycarboxylic acid and salt to built all organic alkaline water treatment agent. Atmp can be used in many different circulating cool water system. The dosage of 1-20mg/l is recommended. As corrosion inhibitor, the dosage of 20-60mg/l is preferred. package and storage::atmp liquid: normally in 250kg net plastic drum, ibc drum can also be used as required atmp solid: 25kg 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:acidity, avoid contact with eye and skin, once contacted, flush with water.

We are offering diphosphonic acidmolecular formula: c2h8o7p2 molecular weight: 206.02structural formula: properties:hedp is an organophosphoric acid corrosion inhibitor. It can chelate with fe, cu, and zn ions to form stable chelating compounds.it can dissolve the oxidized materials on these metals surfaces. Hedp shows excellent scale and corrosion inhibition effects under temperature 250. 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:items indexappearance colorless or light yellow transparent liquid white crystal powderactive contenthedp 58.0-62.0 89.0 minphosphorous acidas po33-% 2.0 max 0.5 maxphosphoric acid aspo43- % 0.8 max 0.5 maxchloride (as cl-)% 0.01 max 0.01 maxph1 solution 2 max 2 maxdensity 20g/cm3 1.40 fe ion ppm 10 max 20 maxcolour 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, etc. 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 electroplating, hedp is used as chelating agent. The dosage of 1-10mg/l is preferred as scale inhibitor, 10-50mg/l as corrosion inhibitor, and 1000-2000mg/l as detergent. Usually, hedp is used together with polycarboxylic acid. Package and storage:hedp liquid: normally in 250kg net plastic drum, ibc drum can also be used as required hedp solid: 25kg inner liner polyethylene (pe) bag, outer plastic woven bag, or confirmed by clients.
