Molecular formula C3H7NO9P3Na5
Relative molecular mass: 409
Structural formula
Ⅰ. Performance and use:
ATMP·Na5 is the sodium salt solution of ATMP, which can prevent scaling salts from forming scale in water, especially the formation of calcium carbonate scale. ATMP·Na5 is used for metal corrosion inhibition in boiler water treatment, oilfield water injection system, industrial and municipal clean water treatment and cooling water treatment. As a universal low-cost scale inhibitor, ATMP·Na5 has a good corrosion inhibition effect on zinc salts and phosphates, and a good chelating performance.
