Inqubo yokudaya ye-anodic oxidation yezingxenye ze-aluminium yethulwa

1. Indlela yokudaya i-monochrome: ngehora lesi-4, imikhiqizo ye-aluminium eye yagcotshwa futhi yagezwa ngamanzi ifakwa ngokushesha kusixazululo sombala. 40-60 ℃. Isikhathi sokucwiliswa emanzini: ukukhanya kwemizuzwana engama-30 ukuya kwengama-3; Kumnyama, kumnyama imizuzu engu-3-10. Ngemva kokudaya, susa futhi ugeze ngamanzi. 2, ukudaya indlela ye-multicolor: uma imibala emibili noma ngaphezulu idayiwe eshidini elifanayo le-aluminium, noma lapho uphrinta indawo, izimbali nezinyoni, umbhalo nombhalo, inqubo izoba yinkimbinkimbi kakhulu, okuhlanganisa indlela yokumboza, ukuphrinta okuqondile kanye nendlela yokudaya. , indlela yokudaya igwebu, njll. Izindlela ezingenhla zisebenza ngokuhlukile, kodwa isimiso siyefana. Manje, indlela yokufihla i-coating ichazwa kanje: Le ndlela ngokuyinhloko iqukethe i-coating encane futhi efana ne-varnish eyomisa ngokushesha futhi kulula ukuyihlanza ephuzi edingekayo ngempela ukuyifihla. Ngemuva kokuthi ifilimu yepende isomile, cwilisa zonke izingxenye ze-aluminium ku-dilute chromic acid solution, susa umbala ophuzi wezingxenye ezingagcotshiwe, hlambulula isisombululo se-asidi ngamanzi, womile ekushiseni okuphansi, bese udaya obomvu. Uma ufuna ukudaya umbala wesithathu nowesine, ungalandela le ndlela. 3. Ukubekwa uphawu: Ngemuva kokuthi ishidi le-aluminium elinebala ligezwe ngamanzi, libiliswa ngokushesha emanzini acwecwe ku-90-100 ℃ imizuzu engu-30. Ngemuva kwalokhu kwelashwa, ingaphezulu liba lifanayo futhi lingenalo i-porous, lenze ifilimu ye-dense oxide. Udayi osetshenziswa ngokufaka umbala ufakwa kufilimu ye-oxide futhi awusakwazi ukusulwa. Ifilimu ye-oxide evala uphawu ayisakhangisi, futhi ukumelana kwayo nokugqoka, ukumelana nokushisa kanye nezakhiwo zokushisa kuyathuthukiswa. Ngemuva kokufakwa uphawu, ingaphezulu lezingxenye ze-aluminium zomiswa futhi ziphuculwe ngendwangu ethambile ukuze kutholwe umkhiqizo we-aluminium omuhle futhi okhanyayo, njengokudaya ngemibala eminingi. Ngemuva kokufakwa uphawu, i-ejenti evikelayo esetshenziswa ezingxenyeni ze-aluminium kufanele isuswe, izindawo ezincane kufanele zisulwe nge-acetone efakwe ukotini, futhi izindawo ezinkulu zingacwiliswa ku-acetone ukuze zigezwe upende. I-1, izingxenye ze-aluminium ngemuva kokwelashwa kwamafutha okugeza, kufanele zifakwe i-oxidized ngokushesha, futhi akufanele zibekwe isikhathi eside kakhulu. Lapho izingxenye ze-aluminium zenziwa amafilimu e-oxide, kufanele zonke zicwiliswe ku-electrolyte, amandla ogesi ebhethri kufanele azinze futhi angaguquki kusukela ekuqaleni kuye ekugcineni, futhi iqoqo elifanayo lemikhiqizo kufanele lilingane ngokuphelele, ngisho noma lidayiwe. 2, phakathi nenqubo ye-anodizing, i-aluminium, ithusi, insimbi, njll. ku-electrolyte iyaqhubeka nokwanda, okuthinta ukucwebezela kwe-aluminium. Uma okuqukethwe kwe-aluminium kukhulu kuno-24g/l, okuqukethwe kwethusi kukhulu kuno-0.02g/l, futhi okuqukethwe kwensimbi kungaphezu kwewashi elingu-2.5 o. I-3, lapho uthenga izinto zokusetshenziswa namadayi, kufanele ukhethe imikhiqizo ehlanzekile kakhulu, ngoba lapho ukungcola okujwayelekile kuthe xaxa noma kuxutshwe ne-anhydrous sodium sulfate ne-dextrin, umphumela wokudaya awumuhle. 4, lapho inani elikhulu lokudaya, isixazululo sokudaya sizoba lula ngemuva kokugxila kokuqala, futhi umbala ngemuva kokudaya uzokhombisa amathoni ahlukene. Ngakho-ke, ukunakwa kufanele kukhokhwe ekuxubeni udayi ogxilile kancane ngesikhathi ukuze kugcinwe ukuhambisana kokugxila kodayi ngangokunokwenzeka. 5. Lapho udaywa ngemibala ehlukahlukene, umbala okhanyayo kufanele udaywe kuqala, bese umbala omnyama udaywe ngophuzi, obomvu, oluhlaza okwesibhakabhaka, onsundu kanye nomnyama ngokushintshana. Ngaphambi kokudaya umbala wesibili, upende kufanele wome ukuze upende usondele endaweni ye-aluminium, ngaphandle kwalokho udayi uzocwiliswa futhi umngcele we-burr ngeke ucace. 6, ukungcola kwe-aluminium kuthinta ukudaya: okuqukethwe kwe-silicon kungaphezu kuka-2.5%, ifilimu engezansi impunga, kufanele idayiwe ibe mnyama. Okuqukethwe kwe-magnesium kukhulu kuno-2%, futhi ibhande lebala alilufifi. Iphansi nge-manganese, kodwa ayikhanyi. Umbala wethusi awulungi, futhi uma uqukethe i-iron eningi, i-nickel, ne-chromium, umbala nawo uba buthuntu.
