Cov khoom

HEDP•Na2 yog organophosphonic acid corrosion inhibitor, nws muaj peev xwm chelate nrog Fe, Cu, thiab Zn ions, nws muaj peev xwm yaj cov oxidized cov ntaub ntawv, nws muaj zoo scale thiab corrosion inhibition cuam tshuam txawm nyob rau hauv 250 degree, nws yog ruaj khov nyob rau hauv siab pH tus nqi, tsis yooj yim rau hydrolyzed, tsis yooj yim rau decomposed nyob rau hauv lub teeb thiab chloride cua sov li qub, tsis yooj yim rau decomposed nyob rau hauv ib txwm lub teeb thiab chloride cua sov. uas ntawm lwm cov organophosph-onic acids. HEDP•Na2 tuaj yeem tsim rau -ntiv nplhaib chelating compounds nrog hlau ions hauv dej, Ca2+ tshwj xeeb. HEDP•Na2 muaj qhov cuam tshuam zoo ntawm qhov cuam tshuam thiab pom tseeb qhov cuam tshuam qhov pib. Thaum siv nrog lwm cov tshuaj kho dej, cov teebmeem kev sib koom ua ke zoo dua.
