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 goodcorrosion inhibition.
ATMP is used inindustrial circulating cool water system andoilfield water pipeline in fields of thermal power plant andoil refinery plant.ATMP can decrease scale formation and inhibit corrosion of metal equipment and pipeline.ATMP can be used aschelating agent in woven and dyeing industries and asmetal surface treatment agent.
The solid state ofATMP 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 inwoven & dyeing industries and as metal surfacetreatment agent.
