Ukusetyenziswa komlingo kweJenereyitha yoMphunga kwiiMveliso zeAluminiyam

I-aluminiyam oxide ngokwenene yi-aluminiyam oxide okanye ialloyi ye-aluminiyam. Zininzi iindlela zokukhupha ialuminiyam, kwaye zonke ziyasebenza. I-aluminiyam oxidation inezinto ezithile. Umphezulu we-aluminium oxidized uya kuba namandla adsorption anamandla kunye ne-porosity ephezulu, eya kubangela ukuba i-aluminiyam ingcoliseke ngokulula emva kwe-oxidation. Ngoko ke, emva kwe-oxidation ye-anodic, ifilimu ye-oxide idinga ukutywinwa, ukwenzela ukuba kuphuculwe ngakumbi ukuxhatshazwa kwe-corrosion kunye nokuxhatshazwa kokugqoka. Umzekelo, ukutywinwa kwamanzi abilayo kunye nomphunga, ukutywinwa kwetyuwa ye-hydrolytic, ukutywinwa kwe-dichromate, ukugcwalisa kunye nokutywinwa. Amanzi abilayo kunye neendlela zokutywinwa komphunga nazo zezona ndlela ziqhelekileyo zokutywina.
Indlela yokutywinwa komphunga wamanzi abilayo yi-chemical oxidation reaction, ikakhulu ukuvumela i-alumina ukuba ingene kwi-oxidation ye-anhydrous phantsi kweemeko eziphezulu zokushisa. Emva kwe-oxidation ye-anhydrous, iba yi-monohydrate, kwaye umthamo we-oxide uyanda kwaye i-oxidized ibe yi-trihydrate. Xa zidityanisiwe, iioksidi zonyusa umthamo ngakumbi. Phakathi kwabo, indlela yokutywinwa kwamanzi abilayo kukubeka i-aluminiyam ene-oxidized emanzini ashushu, kunye nefilimu ye-oxide kudonga lwangaphakathi lwe-barrier layer kunye ne-porous layer iya ku-hydrated kuqala, kodwa kukho ukungafani phakathi kwezi zimbini, eziya kuthi. yenza ukuba umzantsi womngxuma uvalwe de uvalwe ngokupheleleyo. , umjikelo wamanzi awuyi kuqhubeka, kwaye i-oxidation yamanzi abilayo iqala ukusuka kumphezulu we-membrane layer de i-gap ngasemva ivaliwe.
Ngokuqinisekileyo, ukutywinwa komphunga kuya kusebenza ngakumbi ekuvaleni izikhewu kunokutywinwa kwamanzi abilayo. Ngenxa yoko, ezinye izityalo zokuvelisa i-aluminium oxidation ziye zaqalisa ukusebenzisa iijenereyitha zethu zomphunga, ezinokunqanda izikhewu ukuba zingavalwa kangangoko kunokwenzeka, zinokuphucula kakhulu ukusebenza kakuhle kwefektri, kunye nokuphuculwa kwenkqubo ye-aluminium oxidation kunye nokuphucula. zomgangatho weemveliso ze-aluminiyam ziye zavumelana kwimarike Kuhle kakhulu.
Kutheni kungcono ukusebenzisa ijenereyitha yomphunga kwi-aluminiyam oxidation? Enyanisweni, ngexesha lenkqubo ye-aluminium oxidation, i-generator ye-steam inokufikelela ngokukhawuleza kwiqondo lokushisa elifunekayo kwi-aluminium oxidation, kwaye ayiyi kunciphisa ukusebenza kwe-aluminium oxidation okanye kubangele ezinye iingxaki ezingaqhelekanga ngenxa yeengxaki. Ijenereyitha yomphunga inokufudumeza amanzi ashushu, okuthetha ukuba ayiphelelanga nje indlela yokutywinwa komphunga, kodwa kunye nendlela yokutywinwa kwamanzi abilayo inokufezekiswa. Kwizityalo ze-aluminium oxidation, kukho iindlela zokutywina ezinokuthi zikhethwe ngokwazo, ezingenakugcina kuphela izixhobo, kodwa ziphucula ukusebenza kakuhle kwe-aluminium oxidation kunye nokuphucula umgangatho wenkqubo ye-aluminium oxidation.
