Ngwa Anwansi nke Steam Generator na Nhazi Ngwaahịa Aluminom

Aluminom oxide bụ n'ezie aluminom oxide ma ọ bụ aluminom alloy.Enwere ọtụtụ ụzọ iji oxidize aluminum, na ha niile bara uru.Aluminom oxidation nwere ụfọdụ nkọwa.Elu oxidized nke aluminom ga-enwe ike adsorption siri ike na porosity dị elu, nke ga-eme ka aluminom mebie ngwa ngwa mgbe oxidation gasịrị.Ya mere, mgbe anodic oxidation gasịrị, ọ dị mkpa ka a mechie ihe nkiri oxide ahụ, ka ọ na-emewanyewanye nkwụsị nke corrosion ma na-eyi nguzogide.Dịka ọmụmaatụ, mmiri na-esi ísì ụtọ na mkpuchi mkpuchi, hydrolytic salt seal, dichromate sealing, jupụta na akara.Ụzọ esi mmiri esi mmiri na uzuoku akara bụkwa ụzọ a na-ejikarị eme akara.
The esi mmiri vepo sealing usoro bụ kemịkalụ oxidation mmeghachi omume, tumadi na-ekwe ka alumina na-enweta anhydrous oxidation n'okpuru ọnọdụ okpomọkụ dị elu.Mgbe anhydrous oxidation, ọ na-aghọ monohydrate, na olu nke oxide na-abawanye na oxidized n'ime a trihydrate.Mgbe ejikọtara ya, oxides na-abawanye na olu ọbụna karịa.N'ime ha, usoro mmiri esi mmiri na-ekpo ọkụ bụ itinye aluminom oxidized n'ime mmiri ọkụ, na ihe nkiri oxide na mgbidi dị n'ime nke ihe mgbochi mgbochi na oyi akwa porous ga-ebu ụzọ kpoo mmiri, ma e nwere ọdịiche dị n'etiti abụọ ahụ, nke ga- mee ka ala nke oghere ahụ mechie ruo mgbe emechiri ya kpamkpam., okirikiri mmiri agaghị aga n'ihu, na oxidation mmiri na-esi na mmiri na-amalite site na elu nke akpụkpọ anụ ahụ ruo mgbe a na-egbochi oghere dị n'azụ.
