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)
Numera CAS: 2809-21-4
Fuafuaga mole: C2H8O7P2
Fa'aoga
O le HEDP o se ituaiga o fa'agata fa'a'au'au cathodic.Pe a faatusatusa i phosphates inorganic, e mafai ona tuufaatasia ma sodium molybdate, silicate, zinc masima ma co-polymer e masani lava e pei o le inhibitor corrosion fua i le togafitiga o le vai malulu cyclic, moli fanua suauu ma vai vai .E mafai foi ona faaaoga e sequestrant i detergent ma fa'alavelave fa'alavelave ma sausau u'amea i le fa'aeletise.
Uiga
E mafai e le HEDP ona fa'amuta i le lima ion lelei po'o le leaga ma fa'afefete le lua-valent ion i le vai.O le mea lea e mana'omia ai se fua lelei e fa'alavelave ai.O lenei oloa o se faʻamaoniga e faasaga i le maualuga o le vevela, faʻamaʻiina ma le maualuga o le pH.O lo'o fa'aalia ai le lelei atoatoa o le a'afiaga ma le fofoina o le fa'ai'uga a'o fa'apipi'iina ma isi fa'ama'i fa'ama'i ma fa'ama'i fua.
