Yintoni iAnodizing

Emva kokuba iinjineli zoomatshini be-Chengshuo Hardware zigqibe ukuchaneka komatshini kunye novavanyo lobungakanani beprototype yeemveliso zetsimbi, isebe lethu lokulungisa imveliso liya kwenza ucociso oluthe kratya lwasemva kokulungiswa kweemveliso zetsimbi ngokwemekobume apho abathengi basebenzisa iimveliso zetsimbi.

Abantu abaninzi bacinga ngonyango olungaphezulu, kwaye banokulujonga kuphela njengento egqibekayo njengepeyinti kunye nomgubo wokugquma ukuze amalungu abonakale emhle ngakumbi kwaye atshintshe umbala.Enyanisweni, unyango olungaphezulu alukho nje i-aesthetics.Iindlela ezahlukeneyo zonyango lomphezulu ziphatha umphandle weemveliso zetsimbi ngokufaka umaleko obhityileyo owongezelelweyo kumphezulu.Unyango olufanelekileyo lomphezulu lunokunceda iintlobo ezahlukeneyo zeemveliso ezicwangcisiweyo ezichanekileyo zifumana ukhuseleko olungcono kwindawo yokusetyenziswa (njengokumelana nokugqwala, ukunciphisa ukugqwala), ukukhusela iimveliso zetsimbi, kunye nokufezekisa injongo yokwandisa ubomi benkonzo.

Namhlanje siza kukwazisa kuwe imveliso ye-aluminium yemveliso kunye nonyango oluphezulu, i-anodizing, apho i-Chengshuo Hardware inobuchule obukhethekileyo.

Yintoni anodizing?

I-Anodizing yinkqubo ye-electrochemical eguqula umphezulu wesinyithi ube yindawo yokuhombisa, ehlala ixesha elide, kunye ne-anode-resistant-resistant anode oxide surface.I-Aluminiyam ifaneleke kakhulu kwi-anodizing, nangona ezinye iintsimbi ezingenayo i-ferrous ezifana ne-magnesium kunye ne-titanium nazo zinokuthi zenziwe nge-anodized.

Ngo-1923, i-anodizing yaqala ukusetyenziswa kwinqanaba lemizi-mveliso ukukhusela amacandelo e-aluminiyam kwiinqwelomoya ekudlekeni.Ngeentsuku zokuqala, i-chromic acid anodizing (CAA) yayiyinkqubo ekhethiweyo, ngamanye amaxesha ebizwa ngokuba yinkqubo ye-Bengough Stuart, njengoko ichazwe kwiNkcazo yoKhuselo lwase-UK DEF STAN 03-24 / 3.

Uluhlu lwangoku oludumileyo lwe-anodizing

I-Anodizing isetyenziswe ngokubanzi kwishishini ixesha elide.Zininzi iindlela zokusebenzisa amagama ahlukeneyo, kwaye kukho iindlela ezininzi zokuhlela ezinokushwankathelwa ngolu hlobo lulandelayo:

Ihlelwa ngokohlobo lwangoku: DC anodizing;AC anodizing;Kwaye i-anodizing ye-pulse yangoku, enokunciphisa ixesha lokuvelisa ukufezekisa ubukhulu obufunekayo, yenza umaleko wefilimu ungqingqwa, ufanayo kwaye uxinene, kwaye uphucule kakhulu ukuxhathisa umhlwa.

Ngokutsho kwe-electrolyte, inokwahlulwa ibe yi-asidi ye-sulfuric, i-oxalic acid, i-chromic acid, i-asidi edibeneyo, kunye ne-anodic oxidation enemibala yendalo kunye ne-sulfonic organic acids njengesisombululo esiphambili.I-Oxalic acid anodizing yayinelungelo elilodwa lomenzi eJapan ngo-1923 kwaye kamva yasetyenziswa ngokubanzi eJamani, ngakumbi kwizicelo zokwakha.I-Anodized aluminium oxide extrusion yayisisixhobo sokwakha esaziwayo ngeminyaka yoo-1960 kunye noo-1970, kodwa kamva yatshintshwa ziiplastiki ezinexabiso eliphantsi kunye neengubo zomgubo.Iinkqubo ezahlukeneyo ze-asidi ye-phosphoric yenye yophuhliso lwamva nje kunyango lwangaphambili lwamalungu e-aluminium asetyenziselwa ukudibanisa okanye ukupeyinta.Iinguqu ezahlukeneyo eziyinkimbinkimbi kwinkqubo ye-anodic oxidation usebenzisa i-phosphoric acid zisavela.Umkhwa wemigangatho yemikhosi kunye nezoshishino kukuhlela iinkqubo ze-anodizing ngokusekelwe kwiimpawu zokugquma ngaphezu kokuchonga inkqubo ye-chemistry.

Ngokweepropati zoluhlu lwefilimu, lunokwahlulwa lube: ifilimu eqhelekileyo, ifilimu enzima (ifilimu engqingqwa), ifilimu ye-ceramic, i-brand modification layer, i-semiconductor barrier layer, njl. ukwenzela i-anodizing.

Ukuhlelwa kweeNkqubo zeAnodizing yeeMveliso zeAluminiyam

Inkqubo ye-Anodizing ngamanye amaxesha isetyenziselwa ukuvezwa (okungagqunywanga) i-aluminiyam eyenziwe ngoomatshini okanye iindawo ezigayiweyo zekhemikhali ezifuna ukhuseleko lokuchasana nomhlwa.Iingubo ze-Anodic ziquka i-chromic acid (CAA), i-asidi ye-sulfuric (SAA), i-phosphoric acid, kunye ne-boric acid sulfuric acid (BSAA) iinkqubo ze-anodizing.Inkqubo ye-anodizing ibandakanya unyango lwe-electrolytic yesinyithi, apho ifilimu ezinzileyo okanye i-coating yenziwe phezu kwesinyithi.Ukwaleka kwe-Anodic kunokwenziwa kwi-alloys ye-aluminiyam kwii-electrolytes ezahlukeneyo kusetyenziswa umsinga otshintshayo okanye othe ngqo.

I-Anodizing iphunyezwa ngokuntywiliselwa kwe-aluminiyam kwibhafu ye-electrolyte ene-acidic kunye nokudlula okwangoku ngokuphakathi.I-cathode ifakwe ngaphakathi kwetanki ye-anodizing;I-Aluminiyam isebenza njenge-anode, ikhupha i-oksijini ye-oksijini kwi-electrolyte kwaye ibophe kwii-athomu ze-aluminiyam kumphezulu wesahlulo se-anodized.Ke ngoko, i-anodizing yi-oxidation elawulekayo ephucula izinto zendalo.

Anodization ibandakanya Uhlobo I, Uhlobo II, kunye noHlobo III.I-Anodizing yinkqubo ye-electrolytic passivation process esetyenziselwa ukwandisa ubukhulu bomaleko we-oxide yendalo kumphezulu weendawo ze-aluminiyam.Amacandelo e-aluminiyam a-anodized (kungoko kuthiwa "i-anodizing"), kunye nokuhamba kwangoku phakathi kwabo kunye ne-cathode (ngokuqhelekileyo intonga ye-aluminiyam) ngokusebenzisa i-electrolyte ekhankanywe ngasentla (idla ngokuba yi-asidi ye-sulfuric).Umsebenzi ophambili we-anodizing kukunyusa ukuxhathisa kwe-corrosion, ukumelana nokunxiba, ukunamathela kwipeyinti kunye ne-primer, njl.

I-PIC nguCorlee:Uhlobo IIIiindawo zealuminiyam anodized

Isakhiwo se-anode oxide sivela kwi-aluminium substrate kwaye yenziwe ngokupheleleyo nge-aluminium oxide.Olu hlobo lwe-alumina alusetyenziswanga phezulu njengepeyinti okanye iingubo, kodwa luhlanganiswe ngokupheleleyo kunye ne-substrate ye-aluminium ephantsi, ngoko ayiyi kuqhekeza okanye ikhuphe.Inesakhiwo esine-porous esiodolwe kakhulu kwaye sinokuthi sifakwe kwi-secondary processing efana nombala kunye nokutywinwa.
