TETHMP has strong properties of scale and corrosion inhibition and high thermal stability. 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. In addition, TETHMP can form stable adduct with active oxygen compound (e.g.H2O2, etc.) to keep stability of active oxygen. As water quality stabilizer, it can be used to prevent scale in industrial circulating cooling water, dyeing water, low-pressure boiler feed water. It also 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.
