Application

RXSOL-81-8160-250 chemically having wide range of applications including scale prevention and corrosion inhibition in water treatment. 

Hydroxy Ethylidene -1,1-Diphosphonic acid is organophosphonate with multifunctional properties like sequestration, deflocculation, threshold inhibition and hydrolytic stability, as a single active ingredient. Because of the combination of these properties Hydroxy Ethylidene -1,1-Diphosphonic acid has a wide range of applications. One of the most important applications is in scale prevention and corrosion inhibition in water treatment. 

Using Procedure

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. It is used as a strong chelating agent for metal ions like Ca, Mg & Fe in water treatment, textile applications. Its efficient inhibition for CaCO3 & CaSO4 alone or in combination with low molecular weight polymers. Very effective in protecting metal corrosion. HEDP also having very strong chlorine stability.

Remarks

<div id="cke_pastebin" style="text-align: justify;">
At high temperature of 250 Deg C HEDP also resulting good corrosion and antiscaling effect. <br />
<br />
It's good resistance towards High and Low pH value makes it unique and better than that of other organophosphoric acids (salt). HEDP also resulting high chlorine oxidation tolerance properties.<br />
<br />
HEDP can react with metal ions in water system to form hexa-element chelating complex, with calcium ion in particular. Therefore, HEDP has good antiscale and visible threshold effects. When built together with other water treatment chemicals, it shows good synergistic effects. </div>

Note

<p style="text-align: justify;">
