Applications:
EDTMP芒鈧a5 is a neutral solid product. It is nitrogenous organic polyphosphonic acid, which is a part of cathodic corrosion inhibitor. EDTMP芒鈧a5 can be fully dissolved in water, innocuous and none pollution to environment, has good chemical stability and thermal tolerance. EDTMP芒鈧a5 has good scale inhibition property under temperature 200芒鈥炂? EDTMP芒鈧a5 can dissociate into 8 positive-negative ions, thus can chelate with more than two metal ions to form more than two polymer reticulation complex, the complex can be quickly dissolved in water to destroy the normal crystallization of calcium scale.
Usage:
EDTMP芒鈧a5 shows better scale inhibition effects to calcium sulfate and barium sulfate. Its can be used as scale and corrosion inhibitor for circulating water and boiler water system, chelating agent in non-cyanide electroplating, water-softening agent in dyeing industry, etc.
The solid state EDTMP芒鈧a5 is slightly easy to deliquescence, convenient in transportation and suitable for usage in winter and freezing districts.
Packing and Storage:
For liquid: Normally In 250kg net Plastic Drum, IBC drum can also be used as required. Storage for ten months in room shady and dry place.
For solid: inner liner polyethylene (PE) bag, outer plastic woven bag, or confirmed by clients. Storage for one year in room shady and dry place. |
