Bis(HexaMethylene Triamine Penta (Methylene Phosphonic Acid)) is a high-efficient chelating scale inhibitor. It has a good effect on the carbonate and sulfate scale.BHMTPMPA has good water-soluble properties and heat tolerance.
Diethylene Triamine Penta (Methylene Phosphonic Acid) DTPMPA is innocuous, easy to be dissolved in acid solution. DTPMPA has excellent scale and corrosion inhibition and good thermal tolerance ability.
Ethylene Diamine Tetra (Methylene Phosphonic Acid) Sodium is nitrogenous organic polyphosphoric acid, a part of a cathodic corrosion inhibitor. Its corrosion inhibition is 3~5 times better than that of inorganic polyphosphate. It can be fully dissolved in water, innocuous and no pollution to the environment has good chemical stability and thermal tolerance.
1-Hydroxy Ethylidene-1,1-Diphosphonic Acid is an organophosphorus 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.
Polyhydric alcohol phosphate ester is a new kind of water treatment chemicals. PAPE has a good scale and corrosion inhibition ability. Because more than one polyethylene glycol group is introduced into the molecular, the scale and corrosion inhibition for calcium scale are improved.
Polyamino Polyether Methylene Phosphonae is a new kind of water treatment agent. PAPEMP has high chelation and dispersion effects, a high value of calcium tolerance, and good scale inhibition effects.
