Cov qauv qauv:
Cov khoom
HEDP yog organophosphoric acid corrosion inhibitor. Nws tuaj yeem chelate nrog Fe, Cu, thiab Zn ions los tsim cov chelate ruaj khov. HEDP qhia tau hais tias zoo heev nplai thiab corrosion inhibition cuam tshuam nyob rau hauv kub 250 degree. HEDP muaj cov tshuaj lom neeg zoo nyob rau hauv tus nqi pH siab, nyuaj rau hydrolyzed, thiab nyuaj rau decomposed nyob rau hauv lub teeb pom kev zoo thiab cua sov.Lub xeev ntawm HEDP yog siv lead ua hmoov, haum rau siv nyob rau hauv lub caij ntuj no thiab khov cheeb tsam. Vim nws cov purity siab, nws tuaj yeem siv los ua tus neeg saib xyuas hauv hluav taws xob thiab ua cov tshuaj ntxiv hauv cov tshuaj niaj hnub.
Kev siv
HEDP yog siv los ua nplai thiab kev tiv thaiv corrosion hauv cov dej txias txias, roj teb thiab qis - siab boilers hauv teb xws li hluav taws xob fais fab, tshuaj lom neeg kev lag luam, metallurgy, chiv, thiab lwm yam. Hauv kev lag luam dyeing, HEDP yog siv los ua peroxide stabilizer thiab dye- kho tus neeg sawv cev; Hauv uas tsis yog -cyanide electroplating, HEDP yog siv los ua tus neeg sawv cev chelating.
Ntim thiab Cia
HEDP kua: Nquag Hauv 250kg net Yas Drum, IBC nruas kuj tuaj yeem siv raws li qhov xav tau
Cia rau kaum lub hlis hauv chav ntxoov ntxoo thiab qhuav qhov chaw.
Kev Tiv Thaiv Kev Nyab Xeeb
Acidity, Tsis txhob sib cuag nrog lub qhov muag thiab tawv nqaij, ib zaug tiv tauj, yaug nrog dej.
