Product Parameters
Product Description:
EDDHA-Na is a kind of efficient dispersant, embrace strong anionic charge. It's stable in chemical performace when under water conditions of heat, pressure and strong acid & alkali. It has good compatability with other components in the formula.
Main indexes:
Index | Standard |
Appearance | Red-brown Liquid |
Content by wt % | 40 min |
pH Value (1% solution) | 6 - 8 |
Chelating Ca+ | 179mg CaCO3/g |
Chelating Mg+ | 150mg MgCO3/g |
Chelating Fe3+ | 230mg Fe3+/g |
Chelating Mn2+ | 102mg Mn2+/g |
Chelating Cu2+ | 125mg Cu2+/g |
Chelating Zn2+ | 138mg Zn2+/g |
Main Application
1. Used as anti-caking agent: a small amount of antisludging agent can make large scale deposits disperse in aqueous solution. EDDHA-Na destroy the growth of scale, and reduce the speed of scale subsidence. In this way, it reach the inhibition effect.
2. Used as chelating agent: The role of chelation is refers to that the chelating agent can generate stable water-soluble complexes with metal ions.
3. Used as dispersant: Dispersion effect makes the coalescence crystals and other particle becoming more difficult.
