ATMP has excellent chelating, low-limit inhibition, and lattice distortion-preventing effects. It can prevent the formation of scale-forming salts in water, especially calcium carbonate scale. ATMP is chemically stable in water and does not easily hydrolyze. At higher concentrations in water, it has good corrosion inhibition effects.
ATMP is used in circulating cooling water systems of thermal power plants and oil refineries, as well as in oilfield reinjection water systems. It can reduce corrosion and scaling of metal equipment or pipelines. ATMP is used as a metal ion chelating agent in the textile printing and dyeing industry, and can also be used as a metal surface treatment agent.
DTPMPA is innocuous, easy to be dissolved in acid solution. DTPMPA has excellent scale and corrosion inhibition and good thermal tolerance ability. DTPMPA can inhibit the scale formation of carbonate, sulfate and phosphate. On situation of alkali environment and high temperature (above 210℃) DTPMPA has better scale and corrosion inhibition effect than other organophosphines.
EDTMPS is a nitrogen-containing organic polyphosphonic acid, belonging to the cathodic corrosion inhibitor category. Compared with inorganic polyphosphates, its corrosion inhibition rate is 3-5 times higher.EDTMPS has good scale inhibition effect on calcium sulfate and barium sulfate scale.
HDTMPA•K6 is soluble in water; it is a good scale inhibitor for calcium sulfate, suitable for use in situations of high pH and high alkalinity. HMDTMPA•K6 can be used for water treatment in boiler and RO membrane treatment. Appearance: Colorless to yellowish transparent liquid Active component (as acid): 21.2-24.6% Active component (as salt): 31.0-36.0% Chloride (as Cl-): 4.0% max Total phosphoric acid (as PO43-)%: 16.8 min Fe, mg/L: 35.0 max Density (20℃)g/cm3: 1.21-1.31 PH (1% water solution): 6.0-8.0
HEDP is an organophosphonic acid scale and corrosion inhibitor that can form stable complexes with various metal ions such as iron, copper, and zinc, and can dissolve oxides on metal surfaces. It maintains good scale and corrosion inhibition at 250℃, remains stable at high pH, is not easily hydrolyzed, and is generally not easily decomposed under light and heat conditions. Its acid and alkali resistance and chlorine oxidation resistance are better than other organophosphonic acids (salts). HEDP can form hexacyclic chelates with metal ions in water, especially calcium ions, thus exhibiting good scale inhibition and a significant solubility limit effect. When used in combination with other water treatment agents, it demonstrates an ideal synergistic effect.

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. HPAA is mainly used as cathode corrosion inhibitor in oilfield refill water system in fields such as steel & iron, petrochemical, power plant and medical industries.
PAPEMP can be used as a scale and corrosion inhibitor in circulating cool water systems and oilfield refill water systems in situations of high hardness, high alkali, and high pH values. CAS No.: 130668-24-5 Molecular weight: 600 Formula: C3H18O9NP3 Package: 250kg Net Plastic Drum, 1250 IBC Drum Origin: Shandong, China Hazard Information: Corrosive, Class 8, UN 3265
PBTC 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.
