Structural Formula:
Tetra Sodium Salt of Amino Trimethylene Phosphonic Acid(ATMP•Na4) is the salt of ATMP,
it can inhibit the scale formation, calcium carbonate in
particular, in water system.
Tetra Sodium Salt of Amino Trimethylene Phosphonic Acid
can be used in circulating cool system in power plant, oil
refinery plant and oilfield refill water system. ATMP•Na4 has good synergistic
effects with other additives, in neutral to acidic
condition, no ammonia smell is let off.
