2-hydroxy-2-phosphate acetic acid HPAA

Good chemical stability, not easy to hydrolysis, not easy to be destroyed by acid and alkali, safe and reliable, non-toxic and non-polluting, can improve the solubility of zinc, has a strong corrosion inhibition, corrosion inhibition performance is higher than HEDP, EDTMP. Mainly used as a metal cathode corrosion inhibitor, widely used in steel, petrochemical, electric power, pharmaceutical and other industries of the circulating cooling water system corrosion and scale inhibition, suitable for use as a low hardness in southern China, easy to corrode water corrosion inhibitor.

Ethyl carboxylic acid dimethylidene phosphonic acid GDMP

It belongs to nitrogen-containing organic phosphonic acid and is a cathode-type corrosion inhibitor. Compared with inorganic polyphosphate, the sustained release rate is 3~5 times higher. It is miscible with water, non-toxic and non-polluting, has good chemical stability and temperature resistance, and still has good scale inhibition effect at 200 ℃.

Amino trimethylene phosphate ATMP

It has good chelation, low limit inhibition and lattice distortion. It can prevent the formation of scale from scale-forming salts in water, especially the formation of calcium carbonate scale. Chemical stability in water, not easy to hydrolysis. When the concentration of water is high, it has a good corrosion inhibition effect.

Ethylenediamine tetramethylene phosphonic acid (sodium) EDTMPS

It is a nitrogen-containing organic polyphosphonic acid, a cathodic corrosion inhibitor, compared with inorganic polyphosphate, the corrosion rate is 3 to 5 times higher. It is miscible with water, non-toxic and non-polluting, has good chemical stability and temperature resistance, and still has good scale inhibition effect at 200 ℃.

Diethylenetriamine pentamethylenephosphonic acid (sodium) DTPMPA

Non-toxic, soluble in acidic solution, good scale and corrosion inhibition effect and good temperature resistance, can inhibit the formation of carbonate and sulfate scale, in alkaline environment and high temperature (above 210 ℃) scale and corrosion inhibition performance is better than other organic phosphine.

Polyol Phosphate PAPE

Is a new type of water treatment agent, with good scale and corrosion inhibition properties and polycarboxylate, organic phosphonate, inorganic phosphate, zinc salt and other water stabilizers miscible well. Is an excellent calcium carbonate scale inhibitor, commonly used in oil refineries, chemical plants, fertilizer plant circulating water, high chloride seawater circulating water system to do corrosion inhibitor.

Polyamino Polyether Methylene Phosphonic Acid PAPEMP

As a new generation of water treatment agent, it has high chelating dispersion performance, high calcium tolerance and excellent scale inhibition performance. The agent can be used as a scale and corrosion inhibitor in circulating cooling water system, especially suitable for high hardness, high alkalinity, high pH circulating cooling water system and oil field water treatment. Calcium carbonate, calcium phosphate, calcium sulfate scale inhibition performance is excellent, at the same time can effectively inhibit the formation of silica scale, and has a good stability of metal ions such as zinc, manganese, iron.
