HL-105 Diethylenetriamine pentamethylene phosphonic acid DTPMPA
Properties:
DTPMPAis a cathode corrosion, which can form a stable complex with a variety ofmetals. DTPMPA can effectively control the precipitation of carbonate, sulfate,phosphate, hydroxyl phosphate, and hydrochloride iron oxide, and effectivelyprevent the production of hard dirt.
DTPMPAis used as a stald corinner, which has good synergistic ability withpolycarboxylic acid salt and nitrite, especially in alkaline solutions, calciumcarbonate is still good for stain resistance. DTPMPA can also form a stablebonus with the compound of lively oxygen to keep the activated oxygen stable.

Usage:
Itcan be used as a metal cleaning agent to remove the oil on the surface of themetal surface. It can also be used for additives, metal ion chews, cyanideelectroplating additives, and precious metal extracts.
DTPMPAis less than 3mg/L. DTPMPA generally does not add dispersant when used or re-use. The concentration of separate use is 10~15mg/L, and the effectiveconcentration is 5~7.5 mg/L.
Packaging and storage:
25ibc or 250ibc plastic drum packaging, placed in a cool and dry place, valid for twoyears.
Safety Protection:
Thisproduct is an acidic liquid, which has a certain corrosion and irritation forthe skin and eyes.
