Amalungu e-aluminiyam anodized anemibala eyahlukeneyo

Ngenxa yobunzima babo kunye namandla aphezulu,ialuminiyam kunye nemigangatho yayo eyahlukeneyo yealloyizisetyenziswa rhoqo izinto zokwakha kumashishini ahlukeneyo, kubandakanya ezonyango, ezemoto, kunye ne-aerospace.Akukhathaliseki ukuba yeyiphi inkqubo yokuvelisa esetyenziselwa ukwenza ezi nxalenye.Ukugqitywa komphezuluKubalulekile ukunyusa iimpawu zomatshini kunye nobuhle bobuhle.

Ngenxa yokuba uluhlu olubanzi lwemibala lunokufakwa phezu komhlabai-anodizing, yeyona ndlela idumileyo yokugqiba umphezulu esetyenziswa kwimveliso yehlabathi.Amalungu e-aluminiyam ayenziwa ukuba aqine kwaye axhathise ngokugqwesileyo ekuvezweni kwendalo esingqongileyo, ngenxa yombala we-anodizing.Ukongeza, ukukwazi ukumelana ne-abrasion kunokufezekiswa ngombala we-anodizing.Eli nqaku liza kushwankathelaInkqubo yeAluminiyam anodizing, iindlela ezahlukeneyo zokufaka imibala, ukuhambelana kombala, kunye neenkqubo ezinxulumeneyo.

Inkqubo yeAluminiyam Anodizing

Ukucoca iindawo ezenziweyo yinyathelo lokuqala kwi-anodizing aluminium, kunye ne-alkaline yokukrola i-alkaline yeyona nto ingcono yokucoca umsebenzi.Zonke iioyile ezikhanyayo kunye nezinye izinto ezinokuphazamisa inkqubo ye-anodizing ziyasuswa ngexesha lenkqubo yokucoca.Ukufakwa kwealkaline kufuneka kwenziwe emva kokucoca ukuphelisa naziphi na iioksidi zendalo eziseleyo kumphezulu.Eyona ndlela ilungileyo kuyo yi-sodium hydroxides.

Isinyathelo esilandelayo kukukhupha iinxalenye ze-aluminiyam eziCociweyo kunye ne-aluminiyam kwisisombululo se-nitric acid ukwenza umphezulu ogudileyo kwaye ulungiselele i-anodizing.

Izigaba ezahlukeneyo zombala we-aluminiyam anodized

Okokugqibela, amacandelo e-Aluminiyam afakwe kwi-electrolyte ye-asidi ye-sulfuric ukwenzela i-anodizing.I-Cathode ifumaneka ngaphandle kwetanki ye-electrolyte.Amacandelo e-aluminiyam adinga ukugqunywa asebenza njenge-anode.Emva koko umbane wombane usetyenziswa kwi-electrode ("+" i-terminal ukuya kwi-anode kunye "-" i-terminal ukuya kwi-Cathode).Ngoku, umsinga wombane uhamba ngesisombululo se-electrolytic kwaye ukhulula ii-ion ze-oxide, eziya kwi-aluminium substrate ukwenza umaleko odibeneyo we-oxide phezu komhlaba.

Imibala kuMalungu eAluminiyam anodized

Ngokubanzi, iinxalenye zeAluminiyam eAnodized zifakwa umbala kusetyenziswa ezi ndlela zine zilandelayo: ukuphazamisa umbala, umbala wedayi, umbala we-electro, kunye nombala odibeneyo.Makhe sihlolisise nganye kuzo ngoku.

Umbala we-Electro

Imibala eyahlukeneyo ifikeleleka ngokulula kwiindawo zealuminiyam enodizekisiweyo kunye neumbala we-electrolytic.Umbala we-Electrolytic usebenzisa iityuwa zetsimbi ezahlukeneyo njenge-agent ye-colorants, apho ii-ion zesinyithi zetyuwa esetyenzisiweyo zifakwe kwimibhobho ye-anodized aluminiyam.Ngoko ke, umbala uxhomekeke kwisinyithi esisetyenziswe kwisisombululo setyuwa.

Inkqubo yombala we-Electro

Njengenxalenye yenkqubo ye-electrolysis, i-anodized surface ifakwe kwiisombululo ezigxininisiweyo zeetyuwa zetsimbi kude kube yilapho i-pigment eyaneleyo iyancipha ukudala umbala ofunekayo.Ngoko, umbala uxhomekeke kwintsimbi esetyenziswe kwityuwa, kwaye ukuqina kombala kuxhomekeke kwixesha lokunyanga (imizuzwana engama-30 ukuya kwimizuzu engama-20).

Ezinye iityuwa zentsimbi eziqhelekileyo kunye nemibala esetyenziswa kumbala we-anodized aluminiyam 

Umbala wedayi

Enye indlela yokwenza umbala we-anodized aluminiyam inxalenye yombala wedayi.Le nkqubo ibandakanya ukudipha nje amacandelo ukuba abe nombala kwitanki equlethe isisombululo sedayi.Ubukhulu bombala kule ndlela buxhomekeke kwizinto ezahlukeneyo ezifana nokugxininiswa kwedayi, ixesha lonyango, kunye nobushushu.

Iinkcukacha zombala wedayi:

Iingcebiso zombala ogqibeleleyo wedayi

·        Ukucoca iinxalenye ze-aluminiyam ye-anodized kubalulekile kuba i-asidi ehlala phezu komhlaba inokuphazamisa inkqubo yokufa.Kwezinye iimeko, ubukho be-asidi buthintela i-aluminium ekudayeni.Ngoko ke, ngaphambi kokuba uqalise ukuhlamba idayi, sebenzisa i-sodium bicarbonate ukuze udibanise.

·        Amanyathelo okuhlamba i-anodizing kunye nedayi kufuneka agqitywe ngaxeshanye, kunye namalungu afakwe kwi-tank edayiweyo ngokukhawuleza ukuba asuswe kwi-anodizing tank.

·        Ukongeza, gcina nayiphi na i-asidi okanye enye into engcolileyo kude netanki yedayi.

Umbala odibeneyo

Iinkqubo ezidibeneyo zombala zidibanisa iindlela ezimbini ezahlukeneyo.Okokuqala, iinqununu ze-aluminium zi-anodized, kwaye iinqununu ze-anodized zinemibala kunye ne-alloys.Ngoko ke, umsebenzi we-alloy ethile kule nkqubo yindlela umbala ophuhliswa ngayo.Ngokusekelwe ekubunjweni kweengxenye ze-aluminium kunye neemeko zokusebenza, uluhlu lombala lunokuvela kwi-bronze yegolide ngokusebenzisa ubhedu obunzulu ukuya kumnyama.

Ukuphazamiseka kombala

Le ndlela ibandakanya ukwandiswa kwesakhiwo sepore kunye nokubekwa kwesinyithi esifanelekileyo ngokusekelwe kwimibala efunekayo kumphezulu wokufumana indawo enemibala.Njengokungathi uya kufumana umbala ozuba-ngwevu ukuba ufake i-nickel.Ngokusisiseko, imibala yokuphazamiseka iveliswa xa ukukhanya kubetha umphezulu we-aluminiyamu anodized kwaye iphinde yahluzwa, ibonakaliswe, okanye ifunxe.

Ukutywinwa-Inkqubo

Inkqubo yokutywinwa

Injongo ephambili yenkqubo yokutywinwa kukumisa iimolekyuli ezingafunekiyo ekufunxeni kwiipores.Ngenxa yokuba izinto zokuthambisa okanye ezinye iimolekyuli ezingamkelwanga ngamanye amaxesha zigcinwa kwi pores, ekugqibeleni zibe negalelo kukonakala komhlaba.Ezinye izinto eziqhelekileyo zokutywina ziyi-nickel acetate, i-potassium dichromate, kunye namanzi abilayo.

1.          Indlela yamanzi ashushu

Insimbi engenasici okanye enye into engasebenziyo idla ngokusetyenziselwa ukwenza itanki yokutywina.Amacandelo e-aluminium enemibala aqala ukucwiliswa emanzini ashushu (200 0F), apho i-aluminium i-monohydrate ifom phezu komhlaba, kunye nokunyuka okuhambelana nomthamo.Ngenxa yoko, iimolekyuli ezingafunekiyo ziyakhutshwa kwi pore.

2.           Indlela ye-Nickel Fluoride

Le nkqubo ithambisa amalungu e-aluminiyam anodized.Ngale ndlela, i-nickel ye-fluoride ifakwe kwi-anodized aluminium.I-fluoride ion ngoku iya kwi-pores, apho i-nickel ion idlula phezu komhlaba kwaye yenza i-nickel hydroxide ngokudibanisa nama-molecule amanzi, ekugqibeleni ivimbele ii-pores.

3.          Indlela yePotassium Dichromate

Obu buchule busebenzisa isisombululo se-potassium dichromate (5 % w/V) ukutywina amacandelo e-aluminiyam anodized.Okokuqala, amacandelo antywiliselwa malunga nemizuzu eyi-15 kwitanki enesisombululo esibilisayo se-potassium dichromate.Emva koko, umphezulu wamalungu ufunxa ii-ion zechromate, kwaye ukugquma kwenzeka xa ezi ion ziba hydrated.Ngaphandle kokunganyangeki kancinci kunezinye iindlela zokutywina, le ngubo isabonelela ngendlela ethe ngqo yokutywinwa.

Ukudibanisa Umbala

Umbala ohambelanayo unokwahluka ngokwebhetshi ezahlukeneyo;kunjalo, Ukuba ulandela ngqo inkqubo yombala kwiindawo anodized aluminiyam.Ngenxa yoku, inkqubo kunye nezinye izinto ezifana nebakala le-aluminiyam esetyenzisiweyo, uhlobo lokugqiba, uxinaniso lokufa, kunye nolwakhiwo lwekristale lomphezulu kufuneka luphantse lufane kwiibhetshi ukufumana umbala ohambelanayo.

Ukuqukumbela

Emva kokuphonononga i-anodizing kunye nemibala yamacandelo e-aluminium, kucacile ukuba inzuzo engcono ye-aluminiyam anodizing kukukwazi ukufaka imibala eyahlukileyo kumphezulu, engaphuculi nje iipropati zoomatshini kunye nobuhle bobuhle kodwa ihlangabezana neemfuno zemarike.Ngaphaya koko, indlela ye-electro-coloring yeyona igqwesileyo kwiindlela ezine zokufaka imibala kuba ibeka umbala ngokwe-electrochemically kwaye ivumela ukudala uluhlu olubanzi lwemibala ngokulula ngokukhetha isisombululo esifanelekileyo setyuwa.

Ngaphandle kwamathandabuzo, inkqubo ye-aluminiyam anodizing intsonkothile kuba ibandakanya uninzi lwekhemistri, isayensi yezinto eziphathekayo, kunye nokuveliswa kwezobunjineli.Nangona kunjalo, akuyi kubakho nakuphi na ukubhideka ukuba ukhetha yethuinkonzo ye-anodizing. Inzululwazi yethu yezinto eziphathekayo kunye nobunjineli boomatshiniIingcali ziya kukubonelela nge-aluminiyam anodizing yowona mgangatho uphezulu, kwaye unokukhetha umbala ofanele iprojekthi yakho.
