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 No: 2809-21-4
Cov mis molecular: C2H8O7P2
Siv
HEDP yog ib hom tshuaj cathodic corrosion inhibitor. Piv nrog rau inorganic phosphates, nws tuaj yeem sib xyaw nrog sodium molybdate, silicate, zinc ntsev thiab co-polymer feem ntau yog cov tshuaj scale corrosion inhibitor hauv kev kho dej txias cyclic, roj teb flash thiab boiler dej. Nws kuj tseem siv tau ua sequestrant hauv detergent thiab complexing agent thiab hlau scour hauv electroplating.
Yam ntxwv
HEDP tej zaum yuav debond rau tsib ions zoo lossis tsis zoo thiab chelate ob-valent hlau ion hauv dej. Yog li nws muaj qhov zoo ntawm kev tiv thaiv nplai. Cov khoom no yog pov thawj tiv thaiv qhov kub siab, oxidizing thiab pH siab. Nws qhia tau zoo meej synergic nyhuv thiab daws qhov teeb meem thaum sib xyaw nrog lwm cov tshuaj tiv thaiv xeb thiab cov tshuaj tiv thaiv nplai.
