HEDP

Hydroxyethylidene diphosphonic acid (HEDP) yog cov organic phosphonic acid-based scale thiab corrosion inhibitor uas tsim cov complexes ruaj khov nrog ntau yam hlau ions, xws li hlau, tooj liab, thiab zinc, thiab yaj cov oxides ntawm cov hlau.

Nws tseem ua tau zoo hauv kev tiv thaiv kev xeb thiab kev tsim nplai txawm tias ntawm 250 ° C, tseem ruaj khov ntawm cov pH siab, thiab tiv taus hydrolysis. HEDP ua pov thawj zoo dua tiv taus cov kua qaub, alkalis, thiab chlorine oxidation dua li lwm cov organic phosphonic acids (thiab lawv cov ntsev).
