HEDP Cas 2809-21-4 Etidronic Acid Monohydrate
1-Hydroxyethylidene-1,1-diphosphonic acid HEDP CAS 2809-21-4
1-Hydroxyethylidene-1,1-Diphosphonic Acid (HEDP)
CAS Nr .: 2809-21-4
Cov mis mos molecular: C2H8O7P2
Siv
HEDP yog ib hom cathodic corrosion inhibitor. Piv nrog inorganic phosphates, nws tuaj yeem sib xyaw nrog sodium molybdate, silicate, zinc ntsev thiab co-polymer feem ntau yog cov nplai corrosion inhibitor hauv kev kho cov dej txias cyclic, roj teb flash thiab boiler dej.
Yam ntxwv
HEDP yuav debond rau tsib ions zoo los yog tsis zoo thiab chelate ob-valent hlau ion nyob rau hauv dej. Yog li nws yuav siv sij hawm zoo scale inhibiting nyhuv. Cov khoom no yog pov thawj tiv thaiv kub, oxidizing thiab siab pH nqi. Nws qhia tau hais tias zoo meej synergic nyhuv thiab daws qhov pib tshwm sim thaum yuav compounded nrog rau lwm yam corrosion inhibitors thiab scale inhibitors.

Kev siv
HEDP tuaj yeem sib xyaw nrog hydroxylaectic acid, PAA, BTA, molybdate, copolymer, zinc ntsev, ua kom tag nrho-organic-alkali lossis qis-phosphor zinc-raws li tus neeg sawv cev ntawm kev kho dej kom siv tau rau txhua yam ntawm cov dej txias cyclic sib txawv ntawm cov dej zoo. Qhov koob tshuaj feem ntau yog 2 ~ 10mg / L thaum HEDP siv ib leeg.
Pob thiab Cia
250kg yas nruas los yog 1250kg IBC, yuav tsum tau muab cia rau hauv txias thiab ventilated chav tsev nrog ib tug txee lub sij hawm ntawm ib xyoos.
