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)
Nọmba CAS: 2809-21-4
Ụdị ihe omimi: C2H8O7P2
Jiri
HEDP bụ ụdị ihe mgbochi corrosion nke cathodic. E jiri ya tụnyere inorganic phosphates, ọ nwere ike na- compounded na sodium molybdate, silicate, zinc nnu na co-polymer tumadi dị ka ọnụ ọgụgụ corrosion inhibitor na ọgwụgwọ nke cyclic jụrụ mmiri, mmanụ ubi flash na ji esi mmiri ọkụ .It nwekwara ike na-eji dị ka sequestrant na detergent na complexing gị n'ụlọnga na metal scour na electroplating.
Njirimara
HEDP nwere ike kechie ya na ion ise dị mma ma ọ bụ nke na-adịghị mma ma chelate ion ọla-valent abụọ n'ime mmiri. N'ihi ya, ọ na-ewe ezigbo ọnụ ọgụgụ na-egbochi mmetụta. Ngwaahịa a bụ ihe akaebe megide oke okpomọkụ, oxidizing na uru pH dị elu. Ọ na-egosi mmetụta synergic zuru oke yana idozi nsonaazụ ọnụ ebe a na-ejikọta ya na ihe mgbochi corrosion ndị ọzọ na ihe mgbochi ọnụ ọgụgụ.
