Umahluko phakathi kweCopper kunye neAluminiyam yeRadiator

Okwangoku, iijeneretha ezininzi kwiimarike zihambelana neeradiyetha ze-aluminium.Sonke siyazi ukuba iiradiyetha ze-aluminium azikho njenge-thermal conductive njengobhedu.Ngoko ke yeyiphi ixesha elide kubomi benkonzo?Ngaba indawo ephantsi yokunyibilika kwe-aluminium ichaphazela ubomi benkonzo?Indawo yokunyibilika kobhedu yi-1084.4°C, kwaye eye-aluminiyam yi-660.4°C.Nangona kunjalo, ngenxa yokuba i-diesel generator iqulethe izixhobo zokukhusela ukushisa, ayiyi kufikelela kweli qondo lokushisa.Ngokuchasene noko, amanzi obushushu obuphezulu amisela ubomi beradiyetha.Amanzi kubomi bethu bemihla ngemihla ayingomanzi acocekileyo.Iqulethe i-ion ezahlukeneyo, ngakumbi i-concentration ye-chloride ion.Xa i-copper idibana nee-ion ezisebenzayo ezifana ne-Cl- kunye ne-SO42- emanzini, iya kuvelisa ii-ion ezisebenzayo eziqulethe ezi ion ezisebenzayo.Imveliso yokusabela kunye namanzi avelisa iasidi.I-SO2, i-CO2, kunye ne-H2S emoyeni echithwe emanzini iya kunciphisa ixabiso le-PH yendawo.Ukungena kobhedu kuya kukhawulezisa ukubola kobhedu kwaye kubangele ukubola kwemigodi kwiradiyetha yobhedu kunye nombhobho wamanzi ashushu wobhedu.

Iradiyetha yealuminiyam ye ijenereyitha ayikwazi ukuphepha ukukhukuliseka kwamanzi, kwaye i-Cl- iya kutshabalalisa ifilimu ekhuselayo ye-aluminium.I-Cl- ingena kwifilimu ekhuselayo ngokusebenzisa iipores okanye iziphene kwi-aluminium surface, ukwenzela ukuba ifilimu yokukhusela kwi-aluminium surface i-colloidal kwaye ihlakazeke.Ifilimu ekhuselayo ye-Al2O3 idlula i-hydration kwaye ibe yi-hydrated oxide, eyanciphisa umphumo wokukhusela.Ngaphezu koko, i-Cu2 + eyenziwe emva kokuba iindawo zobhedu zigxunyekwe ziya kukhawulezisa ukubola kwe-aluminium.Ukongezelela, i-SO2 emoyeni ibhengezwa yifilimu yamanzi kwi-aluminium surface, ukuchithwa ukuvelisa i-H2SO3 (i-asidi ye-sulfurous) kunye nokusabela nge-oksijini ukuvelisa i-H2SO4 ukugqwesa umphezulu we-aluminium.Xa i-Cl-enokusasazwa okunamandla kunye namandla angenayo itshabalalisa ifilimu ekhuselayo ye-aluminium, i-SO2-i-contacts kunye ne-aluminium matrix kwakhona, kwaye i-corrosion iyenzeka.Lo mjikelo wonyusa ukubola kwealuminiyam.Njengoko ulandelelwano lwe-aluminiyam olunokonakala luphezulu kakhulu kunobhedu, phantsi kwesenzo se-electrolytes efana namanzi, xa i-aluminium idibanisa ezi zinyithi, isibini se-galvanic senziwe.I-Aluminiyam yi-anode.I-galvanic corrosion iya kwandisa ukubola kwe-aluminium ngokukhawuleza.Ke ngoko, ubomi beradiyetha ye-aluminiyam abukade bubude njengobo beradiyetha yobhedu.

Umahluko phakathi kwayo yonke i-copper kunye nazo zonke ii-radiator zetanki zamanzi ze-aluminiyam zezi: impembelelo eyahlukileyo yokutshatyalaliswa kobushushu, ukuqina okwahlukileyo kunye ne-antifreeze eyahlukileyo.

1.Iziphumo ezahlukeneyo zokutshatyalaliswa kobushushu

1.1.Yonke irediyetha yetanki yamanzi yobhedu: isiphumo sokuphelisa ubushushu sayo yonke ireyitha yetanki yamanzi yobhedu ingcono kunayo yonke iradiyetha yetanki yamanzi e-aluminiyam.Impembelelo yokushisa ubhedu ingcono kune-aluminium, ekulula ukukhupha ukushisa.

1.2.Yonke i-radiator yetanki yamanzi ye-aluminium: impembelelo yokutshatyalaliswa kobushushu bayo yonke i-radiator yetanki yamanzi i-aluminiyam imbi kakhulu kunayo yonke i-radiator yetanki yamanzi yobhedu, kunye nefuthe lokuqhuba ubushushu be-aluminiyam libi kakhulu kunobhedu, ngoko akulula ukulahla. ubushushu.

2.Ukuqina okungafaniyo

2.1.Yonke irediyetha yetanki yamanzi yobhedu: ukuqina kwayo yonke iradiyetha yetanki yamanzi yobhedu kungcono kunayo yonke iradiyetha yetanki yamanzi ye-aluminiyam.Umaleko wecopper oxide uxinene kakhulu kwaye unokumelana ne-corrosion ephezulu.

2.2 Yonke iradiyetha ye-aluminiyam yetanki yamanzi: ukuqina kwayo yonke iradiyetha yetanki yamanzi ye-aluminiyam kubi kakhulu kunoko kwereyetha yetanki yamanzi yobhedu.Umaleko we-aluminiyam oxide ukhululekile kakhulu kwaye ukuxhathisa umhlwa kuphantsi.

3.I-antifreeze yahlukile

3.1.Yonke i-radiator yetanki yamanzi yobhedu: yonke i-radiator yetanki yamanzi yobhedu inokusebenzisa amanzi njenge-antifreeze ngaphandle kokuthintela itanki yamanzi.

3.2.Yonke i-radiyetha ye-aluminiyam yetanki yamanzi: yonke i-radiyetha ye-aluminiyam yetanki yamanzi ayinakusebenzisa amanzi njenge-antifreeze, kodwa kufuneka isebenzise isinqandisi esifanelekileyo.Ukongeza amanzi kuya kubangela ukuvaleka kwetanki yamanzi.

Ngokokuhlelwa kwezinto: iradiyetha yenkqubo yokupholisa injini yahlulwe ibe yitanki yamanzi yobhedu kunye netanki yamanzi e-aluminiyam.

Ngokohlelo lwesakhiwo seradiyetha, iradiyetha yenkqubo yokupholisa injini yahlulwe ibe luhlobo lwebhanti yetyhubhu kunye nodidi lweplate fin.Idityaniswe nezinto, iradiyetha eqhelekileyo yenkqubo yokupholisa injini kwimarike ikakhulu ibhanti lombhobho wobhedu, ibhanti lombhobho we-aluminiyam kunye nefin yepleyiti ye-aluminium.

Izinto eziluncedo kwirediyetha yetanki yamanzi yobhedu:

Umbhobho wobhedu onetanki yamanzi, ukuhanjiswa kobushushu okukhawulezayo kunye nokusebenza kakuhle kokutshabalalisa ubushushu.Amanzi anokusetyenziswa njenge-antifreeze

Ngoku akukho phantse ubhedu olucocekileyo kunye ne-aluminium iitanki zamanzi iiradiyetha , zonke zongezwa kunye namanye amacandelo.

Ixabiso xa lilonke letanki yamanzi e-aluminiyam liphantsi kunelo letanki yamanzi yobhedu.Ifanelekile kwi-radiator yendawo enkulu.I-aluminiyam ipleyiti ye-fin yamanzi itanki inokuthembeka okulungileyo kunye nokuqina.

Akungabazeki ukuba iiradiyetha zobhedu zibiza kakhulu kuneeradiyetha ze-aluminium.Ngenkqubela phambili yetekhnoloji ye-aluminiyam yetanki yamanzi, ezinye iinkampani eziqwalasela iindleko zokusebenza ziye zaqala ukwamkela ngokubanzi i-radiator ye-aluminiyam yamanzi.

Ukuqina kobhedu kungcono kunoko kwe-aluminiyam.Isizathu esona sizathu kukuba i-oxide layer ye-aluminium ikhululekile kakhulu, i-oxide layer yobhedu ixinene kakhulu, kwaye ukuxhathisa kwe-corrosion ye-copper substrate kuphezulu kakhulu kune-aluminium.Ngoko ke, kwindawo enomhlwa kancinane, njengamanzi endalo, iasidi ebuthathaka, isisombululo sealkali esibuthathaka kunye nokusingqongileyo kwetyuwa, i-aluminiyam iya kuqhubeka igqwala de ibe ngumhlwa, ngelixa umaleko we-oxide wobhedu akukho lula ukonakala, i-substrate. Iyakwazi ukumelana nomhlwa kwaye inokuqina okufanelekileyo kwendalo.

Ngoko ke, xa ucinga ukusebenzisa uhlobo lweradiyetha, ungenza isigqibo ngokweemfuno zakho, ezifana nemeko yofakelo kwisiza, indawo yokusebenza njalo njalo. .com, siya kukukhokela ukuba ukhethe imveliso efanelekileyo.
