Cov qauv qauv:

Khoom:

HEDP•Na₂ yog ib qho 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 ℃, nws yog ruaj khov nyob rau hauv high pH nqi, tsis yooj yim rau. yuav hydrolyzed, tsis yooj yim rau decomposed nyob rau hauv ib txwm lub teeb thiab kub kub, nws cov acid / alkaline thiab chloride oxidation kam rau ua yog zoo dua li ntawm lwm yam organophosph-onic acids. HEDP•Na₂ tuaj yeem tsim rau lub nplhaib chelating sib txuas nrog cov hlau ions hauv dej, Ca2+ tshwj xeeb. HEDP•Na₂ muaj qhov zoo scale inhibition cuam tshuam thiab pom meej dissolution pib cuam tshuam. Thaum siv nrog lwm cov tshuaj kho dej, cov teebmeem kev sib koom ua ke zoo dua.
