hóa chất amino trimethylene phosphonic acid (ATMP)

hóa chất amino trimethylene phosphonic acid (ATMP)
CAS No. 6419-19-8
Molecular Formula: N(CH2PO3H2)3
MolecularWeight: 299.05
ATMP has excellent chelation, low threshold inhibition and lattice distortion ability. It can prevent
scale formation, ... calcium carbonate in particular, in water system. ATMP has good chemical
stability and is hard to be hydrolyzed in water system. At high concentration, it has good corrosion
inhibition.
ATMP is used in industrial circulating cool water system and oilfield water pipeline in fields of
thermal power plant and oil refinery plant. ATMP can decrease scale formation and inhibit
corrosion of metal equipment and pipeline. ATMP can be used as chelating agent in woven and
dyeing industries and as metal surface treatment agent.
The solid state of ATMP is crystal powder, soluble in water, easily deliquescence, suitable for
usage in winter and freezing districts. Because of its high purity, it can be used in woven & dyeing
industries and as metal surface treatment agent.

Usage:
ATMP is usually used together with organophosphoric acid, polycarboxylic acid and salt to built all
organic alkaline water treatment agent. ATMP can be used in many different circulating cool water
system. The dosage of 1-20mg/L is recommended. As corrosion inhibitor, the dosage of 20-
60mg/L is preferred.
