Product Details

HEDP Na

Mono-sodium of 1-Hydroxy Ethylidene-1,1-Diphosphonic Acid (HEDPNa)

CAS29329-71-3

Alias: Second-ethylene alendronateDequest2016A

C2H7O7P2 Na

First, product performance
HEDP Na is a kind of organic phosphonic acid corrosion inhibitor and scale, with iron, copper, zinc and other metal ions to form a stable complex, to dissolve the surface of metal oxide. In the next 250still play a good role in corrosion and scale inhibitors in high pH stability is still under difficult to hydrolysis, light and heat conditions in general difficult to break down. Acid, oxidation-resistant than other organic acid (salt) good. With metal ions in the water, in particular the formation of six calcium chelate ring, and thus be better and have the effect of scale soluble obvious effects are limited, and other water treatment agent using the compound has shown the desired synergy .
HEDP Na acid formula best suited to the scale agents and detergents, HEDP Na is the second cross-B single-acid sodium salt, applied to clean metal, metal processing and metal ions such as control of the application.
