Phantsi kwe-electrolyte ehambelanayo kunye neemeko ezithile zenkqubo, i-aluminium kunye nee-alloys zayo zenza ifilimu ye-oxide kwimveliso ye-aluminium (i-anode) ngenxa yesenzo sombane osetyenziswayo. Injongo kukunqoba iziphene zobunzima bomphezulu kunye nokumelana nokuguguleka kwe-aluminium alloy, ukwandisa ububanzi bokusetyenziswa kunye nokwandisa ubomi benkonzo.
Yintoni i-anode?
Kwibhetri yamakhemikhali, i-electrode enokuxovula i-electrolyte ibizwa ngokuba yi-anode.
Kukho iintlobo ezininzi zezisombululo ezisetyenziswa kwi-anodizing. Okwangoku ezisetyenziswa kakhulu yi-sulfuric acid, i-oxalic acid, i-malonic acid, i-sulfonic acid njalo njalo. Eyona ixhaphakileyo kwezi kukusetyenziswa kwe-sulfuric acid njengesisombululo sonyango lwe-oxidative. Iingenelo zezokuba ifilimu ye-oxide exineneyo inokufunyanwa, ubunzulu befilimu ye-oxide nayo inkulu, isizalisi sinokumanziswa ngcono, kukho iintlobo ezininzi kunye neenkcukacha zezinto ze-aluminium ezifanelekileyo, iteknoloji yokusebenza ayinzima, kwaye ukusetyenziswa kwamandla kuphantsi.
Kutheni iindawo ze-aluminium zi-anodized?
1. Ithrekhi yomatshini wokugquma.
Emva komatshini wokugaya we-CNC, kuhlala kukho imigca yezixhobo kumphezulu weendawo ze-aluminiyam. Ukuba abathengi bafuna ukuphucula "inkangeleko" yeendawo ze-aluminiyam, uninzi lwabo lukhetha ukusebenzisa i-sandblasting + anode yokulungisa umphezulu.
2. Ukuphucula ukumelana nokugqwala.
Enyanisweni, i-aluminium alloy yintsimbi ekwaziyo ukumelana nokugqwala kuba i-aluminium iyasebenza kakhulu kwaye ithambekele kakhulu kwiimpendulo zeekhemikhali kunye neoksijini emoyeni ukuze yenze i-aluminium oxide. Ifilimu ye-aluminium oxide ebonakalayo ayibonakali emehlweni omntu. Le filimu incinci ye-aluminium oxide iyawuhlukanisa umoya ukuze i-substrate ye-aluminium ingangcoliswa. Ifilimu ye-oxide yendalo isebenza njenge-anti-oxidant.
3. Phucula ukumelana nokuguguleka.
I-aluminium ithanda kakhulu ukukrweleka nokuguguleka, kwaye ubunzima bee-alloys ze-aluminium abunakuthelekiswa nentsimbi emva kwayo yonke loo nto. Umphezulu weprofayili ye-aluminium yemizi-mveliso eyosiweyo uqinile kakhulu, kwaye ubunzima befilimu ye-oxide bufikelela kwi-300HV. Ke ngoko, ayigugi kakhulu kwaye akulula ukuyikrwela.
4. Umbala womphezulu weemveliso ze-aluminium zokuhombisa.
Ngaphambi kokufakwa kwe-aluminium anodization kunye nokuvalwa, kukho imingxuma emininzi exineneyo kumphezulu, okulula ukuyifunxa ityuwa yesinyithi kunye needayi, kwaye umphezulu weemveliso ze-aluminium wenza imibala enemibala.
5. Phucula ubushushu.
I-Aluminium iqhuba umbane kakuhle kakhulu, kodwa i-aluminium ifuna ubushushu kwezinye iimeko. Ifilimu ye-aluminium oxide ene-anodized ayihambisani nombane.
6. Faka ipeyinti kwi-primer.
Ezinye iindawo ze-aluminiyam kufuneka zipeyintwe. Umphezulu we-aluminiyam e-anodized une-adsorption enamandla, kwaye uphahla lufana ngakumbi kwaye luhle.
Ubukhulu befilimu ngokubanzi ye-anodizing esemgangathweni kazwelonke yi-10-20 microns.
Kutheni i-anodizing iyimfuneko?
Kwelinye icala, ngenxa yefilimu ye-oxide engalinganiyo eyenziwe ngokwendalo, umbala womphezulu we-aluminium alloy wahlukile kwaye awubukeki kakuhle.
Kwelinye icala, ifilimu ye-oxide eyenziwe ngokwemvelo ibhityile, yonakala lula, kwaye ibuthathaka ekumelaneni nokugqwala. Ifilimu ye-oxide yokwenziwa eveliswa yi-anodic oxidation iyafana, ixinene kwaye imelana neoyile yokugqwala.
