Properties and usage:
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.
