    SM-3210F Diethylenetriaminepentakis(methylphosphonic acid)

    Chemical structure:



    ◎excellentscale inhibition for calcium carbonate,calcium sulfateand barium sulfate.Inhibiting efficiency is 2~3 times as high as ATMP.Also the corrosion-inhibition   effect issuperior toHEDP and ATMP.

    ◎well scale inhibition in high alkalinity and high hardness water.

    ◎strong chelation forcalcium ion,iron ion,cupric ion,zinc ionand aluminium ion.

    ◎better threshold value.

    ◎well thermostable performance and antioxygenic property.

    ◎efficientcorrosion inhibition for carbon steel equipment 

    ◎low-phosphorous and environmental.
