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 aluminum 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 ụfọdụ ọdịiche dị n'etiti abụọ ahụ, nke ga-eme ka ala nke oghere ahụ mechie ruo mgbe ọ mechiri 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.
N'ezie, mkpuchi uzuoku ga-adị irè karị na nkwụsị nke oghere karịa ịcha mmiri mmiri. N'ihi nke a, ụfọdụ ụlọ ọrụ mmepụta ihe na-emepụta aluminum oxidation amalitela iji ndị na-emepụta ụgbọ mmiri anyị, nke nwere ike izere oghere ndị ahụ ka a ghara igbochi ya dị ka o kwere mee, nwere ike imeziwanye arụmọrụ nke ụlọ ọrụ mmepụta ihe, na imeziwanye usoro oxidation aluminum na mma nke àgwà ngwaahịa aluminom na-ekwughachi n'ahịa dị ezigbo mma.
Gịnị mere na ọ kasị mma iji a uzuoku generator maka aluminum oxidation? N'ezie, n'oge usoro oxidation nke aluminom, onye na-emepụta steam nwere ike rute ngwa ngwa okpomọkụ a chọrọ maka aluminum oxidation, ma ọ gaghị ebelata arụmọrụ oxidation aluminum ma ọ bụ mee ka nsogbu ndị ọzọ na-adịghị mma n'ihi nsogbu. Onye na-emepụta ihe na-ekpo ọkụ nwekwara ike ikpo ọkụ mmiri ọkụ, nke pụtara na ọ bụghị naanị usoro mkpuchi uzuoku nwere ike mezuo, kamakwa usoro ntinye mmiri na-esi esi mmiri nwere ike mezuo. Maka osisi oxidation nke aluminom, enwere ụzọ ntinye akara nke nwere ike ịhọrọ onwe ha, nke nwere ike ọ bụghị naanị ịchekwa ngwá ọrụ, kamakwa melite arụmọrụ nke aluminum oxidation ma melite ọkwa nke usoro oxidation aluminum.
