Properties:
ATMP has excellentchelation, low threshold inhibition and lattice
distortion ability. It canprevent scale formation, calcium
carbonate in particular, in water system. ATMPhas good chemical
stability and is hard to be hydrolyzed in water system. Athigh
concentration, it has good corrosion inhibition.
ATMP is used inindustrial circulating cool water system and
oilfield water pipeline in fieldsof thermal power plant and oil
refinery plant. ATMP can decrease scale formationand inhibit
corrosion of metal equipment and pipeline. ATMP can be used
aschelating agent in woven and dyeing industries and as metal
surface treatmentagent.
The solid state ofATMP is crystal powder, soluble in water, easily
deliquescence, suitable forusage in winter and freezing districts.
Because of its high purity, it can beused in woven & dyeing
industries and as metal surface treatmentagent.

Usage:
ATMP is usually usedtogether with organophosphoric acid,
polycarboxylic acid and salt to built allorganic alkaline water
treatment agent. ATMP can be used in many differentcirculating cool
water system. The dosage of 1-20mg/L is recommended. Ascorrosion
inhibitor, the dosage of 20-60mg/L is preferred.
