Hedp CAS 2809-21-4 etidronic acid monohydrate
1-hydroxyethylidene-1,1-diphosphoronic acid / hedp CAS 2809-21-4
1-hydroxyethylidene-1,1-diphosphonics acid (Hedp)
CAS TSIS: 2809-21-4
Molecular cov mis: c2h8o7p2
Kev siv
Hedp yog ib hom Cathodic corrosion inhibitor. Piv nrog inorganic phosphatic, nws tuaj yeem sib txuas nrog sodium molybdate, silicate, roj flawrosion hauv cov dej txias, roj boiler. Cov neeg sawv cev thiab cov hlau nrov hauv cov electroplating.
Tus yam ntxwv
Hedp kuj yuav tshem tawm mus rau tsib ions zoo lossis tsis zoo thiab khi ob-valent hlau ion hauv dej. Yog li nws tau siv lub teeb tsa zoo inhibiting effect. Cov khoom no yog pov thawj tiv thaiv qhov kub siab, oxidizing thiab PH nqi siab. Nws qhia tau zoo tshaj plaws cov txiaj ntsig zoo tshaj plaws thiab daws cov nyhuv pib thaum lub corrosion inhibitors thiab teev inibitors.
