HEDP 60% 1-Hydroxyethylidene-1,1-diphosphonic acid CAS 2809-21-4 Etidronic acid monohydrate

Nta:
HEDP yog organophosphoric acid corrosion inhibitor. Nws tuaj yeem chelate nrog Fe, Cu, thiab Zn thiab lwm yam.
hlau ions thiab tsim ruaj khov complex compound.
Nws tuaj yeem yaj cov ntaub ntawv oxidized ntawm cov hlau no. Nyob rau hauv 250 ℃ HEDP qhia tau hais tias zoo heev nplai thiab corrosion inhibition muaj peev xwm.
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 lub teeb 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.

Cov khoom ntawm HEDP yog cov khoom siv purity siab, haum rau siv rau lub caij ntuj no thiab khov hauv cheeb tsam.
nws yog qhov tsim nyog rau kev siv los ua tus neeg saib xyuas hauv hluav taws xob thiab ua cov tshuaj ntxiv hauv cov tshuaj txhua hnub.

Daim ntawv thov:
HEDP yog dav siv nyob rau hauv circulating dej txias system ntawm hluav taws xob fais fab, tshuaj kev lag luam, metallurgy, chiv, thiab lwm yam thiab dav siv raws li ib tug scale thiab corrosion inhibitor ntawm low-pressure boilers, teb dej nyab, roj pipeline.

Hauv kev lag luam teeb & textile, HEDP yog siv los ua tshuaj ntxuav tes rau hlau thiab nonmetal. Hauv kev lag luam dyeing, HEDP yog siv los ua peroxide stabilizer thiab dye-fixing tus neeg saib xyuas; Hauv non-cyanide electroplating, HEDP yog siv los ua tus neeg sawv cev chelate. Qhov ntau npaum li cas ntawm 1-10mg / L yog nyiam raws li nplai inhibitor, 10-50mg / L raws li corrosion inhibitor, thiab 1000-2000mg / L ua tshuaj ntxuav. Feem ntau, HEDP yog siv ua ke nrog polycarboxylic acid.
