TETHMP

TETHMP has strong properties of scale and corrosion inhibition and high thermal stability, which decomposition temperature of dry product is 223 ~ 245 ℃. TETHMP is easy to be degraded and safe to use. 

TETHMP is a strong complexing agent with high dissociation degree in water, and can form a stable complex with Ca2+、Mg2+ and other metal ions. TETHMP can dissociate into twelve pairs of positive and negative ions in aqueous solution, chelate with two or more metal ions to form two or more complex of stereo macromolecule structure, loosely dispersed in water to destruct the normal crystalline of scale and prevent scale formation. TETHMP can effectively control the precipitation of carbonates, sulfates, phosphates, hydroxyl phosphates and ferric hydroxide and prevent the hard scale formation. In addition, TETHMP can form stable adduct with active oxygen compound (e.g.H2O2, etc.) to keep stability of active oxygen.

TETHMP can be used as scale inhibitor , efficient chelating agents, excellent barium sulfate scale inhibitor , which is widely used in cooling water treatment, peroxide bleaching stabilizer, detergent additives , municipal industrial clean water , geothermal water treatment and oilfield scale inhibitor.

As water quality stabilizer, it can be used to prevent scale in industrial circulating cooling water, dyeing water, low-pressure boiler feed water. TETHMP also can be used as precious metal extraction agent, metal ions equispaced agent in electroplating industry, scale inhibitor of metal surface phosphate treatment system, cleaning agent of metal surface.
