XF-334(HEDP) |
|
1-Hydroxyethyldene-1,1-Diphosphonic Acid |
|
XF-334 is a multifunctional phosphonate providing all the properties of polyphosphates, phosphate esters, polymers and chelating agents. XF-334 is employed as a scale control agent for cooling water treatment. Besides, it can improve corrosion control, or inhibit iron fouling and assist dispersion of solids. XF-334 is with the following key functions: Threshold effect Hydrolytic stability, Sequestration Chlorine stability, Crystal growth modification Chlorine stability. *Applications: - Scale and corrosion control in cooling water and oilfield water. - Scale control in evaporative desalination and reverse osmosis. - Sludge modification in boiler water. - Stabilization of chemical compounds which are decomposed by trace metals(for example, hydrogen peroxide). - Surface treatment for dairy, metal finishing and industrial operations. - Regeneration and cleaning of ion exchange resins. |
