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 i le sodium molybdate, silicate, zinc masima ma co-polymer e masani lava e pei inhibitor corrosion fua i le togafitiga o le vai malulu cyclic, moli fanua suauu ma vai vai .E mafai foi ona faaaoga e pei o sequestrant i detergent ma complexing sui ma sasa uamea i electroplating.
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.

Fa'aoga
E mafai ona faʻapipiʻiina le HEDP ma le hydroxylaectic acid, PAA, BTA, molybdate, copolymer, zinc masima, e faʻapipiʻi atoa-organic-alkali poʻo le maualalo-phosphor zinc-faʻavae suʻesuʻega vai e faʻaaogaina i ituaiga uma o vai malulu e ese mai le lelei o le vai. Ole fua ole masani ole 2 ~ 10mg / L aʻo faʻaaogaina naʻo le HEDP.
afifi ma teuina
250kg pa'u palasitika po'o le 1250kg IBC, ia teuina i totonu o le potu malulu ma fa'alili ma se fata taimi o le tausaga e tasi.
Pls faʻafesoʻotaʻi matou e maua COA ma MSDS. Fa'afetai.
