Properties:ATMP has excellent chelation, low threshold inhibition
distortion ability. It can prevent scale formation, calcium
particular, in water system. ATMP has good chemical stability and
is hard to
be hydrolyzed in water system. At high concentration, it has good
ATMP is used in industrial circulating cool water system and
pipeline in fields of thermal power plant and oil refinery plant.
decrease scale formation and inhibit corrosion of metal equipment
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.
its high purity, it can be used in woven & dyeing industries
and as metal
surface treatment agent.
