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 ahụ 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.
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 ihe ọkụkụ anyị, nke nwere ike izere oghere ndị ahụ ka a ghara igbochi ya dị ka o kwere mee, nwere ike ime ka arụmọrụ nke ụlọ ọrụ ahụ dịkwuo mma, na mmelite nke usoro oxidation aluminum na mma. nke àgwà ngwaahịa aluminom ekwupụtala 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 mkpuchi ọzọ nke nwere ike ịhọrọ onwe ha, nke nwere ike ọ bụghị naanị ịchekwa akụrụngwa, kamakwa melite arụmọrụ nke oxidation aluminum ma melite ọkwa nke usoro oxidation aluminum.
