Factory Supply HEDP los ntawm Tuam Tshoj CAS: 2809-21-4 nrog High Quality
Cov khoom
HEDP yog ib qho organophosphoric acid corrosion inhibitor. Nws tuaj yeem chelate nrog Fe, Cu, thiab Zn ions los tsim cov chelate ruaj khov. Nws tuaj yeem yaj cov ntaub ntawv oxidized ntawm cov hlau no.
HEDP qhia tau hais tias zoo heev nplai thiab corrosion inhibition cuam tshuam nyob rau hauv kub 250 ° C.
HEDP muaj cov tshuaj lom neeg ruaj khov zoo nyob rau hauv tus nqi PH siab, nyuaj rau hydrolyzed, thiab nyuaj rau decomposed nyob rau hauv cov teeb pom kev zoo thiab cua sov. Nws cov kua qaub / alkali thiab chlorine oxidation kam rau ua zoo dua li lwm cov organophosphoric acids (ntsev).
HEDP tuaj yeem hnov mob nrog cov hlau ions hauv dej los tsim hexa-element chelating complex, nrog calcium ion tshwj xeeb.
Yog li ntawd, HEDP muaj kev tiv thaiv zoo thiab pom qhov pib tshwm sim. Thaum tsim ua ke nrog lwm cov tshuaj kho dej, nws qhia tau hais tias muaj txiaj ntsig zoo.
