Atmpòna5

Usage of HEDP:

Hedp is used as scale and corrosion inhibition in circulating cool water system, oil field and low-pressure boilers in fields such as electric power, chemical industry, metallurgy, fertilizer, etc.. In light woven industry, hedp is used as detergent for metal and nonmetal. In dyeing industry, hedp is used as peroxide stabilizer and dye-fixing agent; in non-cyanide electroplating, hedp is used as chelating agent. The dosage of 1-10mg/l is preferred as scale inhibitor, 10-50mg/l as corrosion inhibitor, and 1000-2000mg/l as detergent. Usually, hedp is used together with polycarboxylic acid.

Package and storage of HEDP:

Hedp liquid: normally in 250kg net plastic drum, ibc drum can also be used as required hedp solid: 25kg inner liner polyethylene (pe) bag, outer plastic woven bag, or confirmed by clients.
Storage for ten months in room shady and dry place.

Usage of ma/aa:
Ma/aa is used in circulating cool water system, medium or lower pressure boiler and distillation system in which high temperature is usually encountered. Ma/aa can be used alone or together with other organic phosphates. When used together, the dosage of 2-10mg/l is preferred. The dosage for use as woven & dyeing and accessory detergent should be determined by experiments.

CAS No.: 15827-60-8.
Molecular Formula: C9H28O15N3P5
Molecular weight: 573.2
Properties:
DTPMPA is innocuous, easy to be dissolved in acid solution. DTPMPA has excellent scale and corrosion inhibition and good thermal tolerance ability. DTPMPA can inhibit the scale formation of carbonate, sulfate and phosphate. On situation of alkali environment and high temperature (above 210íµ) DTPMPA has better scale and corrosion inhibition effect than other organophosphines.

Properties of ATMP:
ATMP has excellent chelation, low threshold inhibition and lattice distortion ability. ATMP 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, ATMP 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, ATMP can be used in woven & dyeing industries and as metal surface treatment agent.
