Ngemva kokuba onjiniyela bemishini ye-Chengshuo Hardware beqede ukunemba komshini kanye nokuhlola usayizi we-prototype wemikhiqizo yensimbi, umnyango wethu wokucutshungulwa komkhiqizo uzokwenza okucwengisiswe kakhudlwana kokucutshungulwa kwemikhiqizo yensimbi ngokwendawo lapho amakhasimende asebenzisa khona imikhiqizo yensimbi.
Abantu abaningi bacabanga ngokwelashwa okungaphezulu, futhi bangase bakubheke njengokuqedwa kobuhle njengopende nokufakwa kwempushana ukuze benze izingxenye zibukeke zizinhle kakhulu futhi zishintshe umbala.Eqinisweni, ukwelashwa okungaphezulu akukona nje okobuhle.Ukwelashwa okuhlukile okungaphezulu kuphatha ingaphandle lemikhiqizo yensimbi ngokufaka ungqimba omncane ongeziwe ongaphezulu.Ukwelashwa kwendawo efanele kungasiza izinhlobo ezihlukene zemikhiqizo ecutshungulwe ngokunemba kwensimbi ukuthola ukuvikeleka okungcono endaweni yokusetshenziswa (njengokumelana nokugqwala, ukunciphisa ukugqwala), ukuvikela imikhiqizo yensimbi, kanye nokufeza umgomo wokwelula impilo yesevisi.
Namuhla sizokwethula ukukhiqizwa komkhiqizo we-aluminium kanye nokwelashwa kwendawo, i-anodizing, i-Chengshuo Hardware enekhono layo ngokukhethekile.
Yini i-anodizing?
I-Anodizing inqubo ye-electrochemical eguqula indawo yensimbi ibe indawo ehlobisayo, ehlala isikhathi eside, futhi ekwazi ukumelana nokugqwala kwe-anode oxide.I-Aluminium ifaneleka kakhulu ekufakweni kwe-anodizing, nakuba ezinye izinsimbi ezingenayo insimbi njenge-magnesium ne-titanium nazo zingagcotshwa.
Ngo-1923, i-anodizing yaqala ukusetshenziswa esikalini sezimboni ukuze kuvikelwe izingxenye ze-aluminium zezindiza zasolwandle ekugqwaleni.Ezinsukwini zokuqala, i-chromic acid anodizing (CAA) kwakuyinqubo ekhethwayo, ngezinye izikhathi ebizwa ngokuthi inqubo ye-Bengough Stuart, njengoba kuchazwe ku-UK Defence Specification DEF STAN 03-24/3.
Isigaba samanje esidumile se-anodizing
I-Anodizing isetshenziswe kabanzi embonini isikhathi eside.Kunezindlela eziningi zokusebenzisa amagama ahlukene, futhi kunezindlela ezimbalwa zokuhlukanisa ezingafingqwa ngale ndlela elandelayo:
Kuhlukaniswa ngohlobo lwamanje: I-DC anodizing;I-AC anodizing;Futhi i-pulse current anodizing, enganciphisa isikhathi sokukhiqiza ukuze kuzuzwe ukushuba okudingekayo, yenze ungqimba lwefilimu lube lukhuni, lufane futhi luminyene, futhi luthuthukise kakhulu ukumelana nokugqwala.
Ngokusho kwe-electrolyte, ingahlukaniswa ibe yi-sulfuric acid, i-oxalic acid, i-chromic acid, i-asidi exutshwe, kanye ne-anodic oxidation enombala ngokwemvelo ene-sulfonic organic acids njengesixazululo esiyinhloko.I-Oxalic acid anodizing yayinelungelo lobunikazi e-Japan ngo-1923 futhi kamuva yasetshenziswa kabanzi eJalimane, ikakhulukazi ezicelweni zokwakha.I-anodized aluminium oxide extrusion kwakuyimpahla yokwakha edumile ngeminyaka yawo-1960s kanye nawo-1970, kodwa kamuva yathathelwa indawo amapulasitiki ashibhile kanye nama-powder coatings.Izinqubo ezahlukahlukene ze-phosphoric acid zingenye yentuthuko yakamuva ekwelapheni kwangaphambili kwezingxenye ze-aluminium ezisetshenziselwa ukubopha noma ukudweba.Izinguquko eziyinkimbinkimbi ezinhlobonhlobo zenqubo ye-anodic oxidation usebenzisa i-phosphoric acid zisavela.Ukuthambekela kwamazinga ezempi nawemboni ukuhlukanisa izinqubo ze-anodizing ngokusekelwe kuzici zokumboza ngaphezu kokuhlonza inqubo yekhemistri.
Ngokusho kwezakhiwo zesendlalelo sefilimu, ingahlukaniswa: ifilimu evamile, ifilimu eqinile (ifilimu ewugqinsi), ifilimu ye-ceramic, ungqimba olukhanyayo lokuguqulwa, ungqimba we-semiconductor barrier, njll. ye-anodizing.
Ukuhlukaniswa Kwezinqubo Ze-Anodizing Yemikhiqizo Ye-Aluminium
Inqubo ye-anodizing kwesinye isikhathi isetshenziselwa i-aluminium eveziwe (engavaliwe) eyenziwe ngomshini noma izingxenye ezigaywe ngamakhemikhali ezidinga ukuvikeleka kokubola.Izembatho ze-Anodic zihlanganisa i-chromic acid (CAA), i-sulfuric acid (SAA), i-phosphoric acid, ne-boric acid sulfuric acid (BSAA) izinqubo ze-anodizing.Inqubo ye-anodizing ihilela ukwelashwa kwe-electrolytic yezinsimbi, lapho ifilimu ezinzile noma ukunamathela kwakhiwa endaweni yensimbi.Ama-anodic coatings angakhiwa kuma-alloys e-aluminium kuma-electrolyte ahlukahlukene kusetshenziswa amandla ashintshayo noma amanje aqondile.
I-anodizing ifinyelelwa ngokucwilisa i-aluminium kubhavu we-electrolyte ene-asidi kanye nokudlulisa umthamo phakathi nendawo.I-cathode ifakwe ngaphakathi kwe-anodizing tank;I-Aluminium isebenza njenge-anode, ikhipha ama-ion omoya-mpilo ku-electrolyte futhi ibophezele kuma-athomu e-aluminium ebusweni bengxenye ye-anodized.Ngakho-ke, i-anodizing iyi-oxidation elawuleka kakhulu ethuthukisa izenzakalo zemvelo.
I-anodization ihlanganisa Uhlobo I, Uhlobo II, kanye Nohlobo III.I-Anodizing iyinqubo yokudlulisa i-electrolytic esetshenziselwa ukukhulisa ukushuba kongqimba lwe-oxide yemvelo ebusweni bezingxenye ze-aluminium.Izingxenye ze-Aluminium zi-anodized (yingakho kubizwa ngokuthi "i-anodizing"), futhi kugeleza kwamanje phakathi kwazo kanye ne-cathode (imvamisa iyinduku ye-aluminium eyisicaba) ngokusebenzisa i-electrolyte eshiwo ngenhla (imvamisa i-sulfuric acid).Umsebenzi oyinhloko we-anodizing ukwandisa ukumelana nokugqwala, ukumelana nokugqoka, ukunamathela kupende kanye ne-primer, njll.
I-PIC ngo-Corlee:Uhlobo IIIizingxenye ze-aluminium anodized
Isakhiwo se-anode oxide sisuka ku-aluminium substrate futhi sakhiwe ngokuphelele nge-aluminium oxide.Lolu hlobo lwe-alumina alusetshenziswa phezulu njengopende noma okokunamathela, kodwa luhlanganiswe ngokuphelele ne-substrate ye-aluminium engaphansi, ngakho-ke ngeke iphahlazeke noma ixebuke.Inesakhiwo esinezimbotshana ezi-ode kakhulu futhi singafakwa ngaphansi kokucutshungulwa kwesibili njengokufaka imibala nokuvala.
