izinga okusezingeni eliphezulu anodizing umshini semi auto aluminium anodizing umugqa
①Ukwelashwa kwephrofayili ye-aluminium:
Ukwelashwa okungaphezulu kwamaphrofayili e-aluminium, okubuye kwaziwe ngokuthi i-surface pretreatment, ukusebenzisa izinto ezibonakalayo namakhemikhali ukususa ukungcola okungaphezulu kwamaphrofayili e-aluminium, ukuze kuvele umzimba wephrofayili ye-aluminium, olungele ukwelashwa kamuva kwe-oxidation ye-aluminium. indawo yephrofayili.
②Inqubo yokwehlisa iphrofayili ye-aluminium:
Inhloso yenqubo yokwehlisa amafutha kumaphrofayili e-aluminium ukususa uwoyela wokugcoba wezimboni kanye namafutha alwa nokugqwala ebusweni bamaphrofayili e-aluminium, kanye nokungcola nokungcola okunamathela ebusweni bamaphrofayili, ukuqinisekisa ukugqwala kwe-alkali okufanayo kwamaphrofayili e-aluminium, kanye ukuqinisekisa ukuhlanzeka kwamathangi e-alkali etching;kanye nokuthuthukisa ikhwalithi yokwelashwa okungaphezulu kwamaphrofayili e-aluminium.
③Inqubo yokufaka i-asidi yephrofayili ye-aluminium:
Inqubo yokufaka i-asidi ebusweni bamaphrofayili e-aluminium iwukwenza ukwelashwa kokugqwala kwe-asidi engaphezulu ngemuva kokugcoba amaphrofayili e-aluminium.Inhloso eyinhloko ukususa ama-oxide akhiwe ngemva kokufakwa kwe-oxidation yezinye izakhi zensimbi ebusweni bamaphrofayili e-aluminium kanye namafilimu e-oxide akhiwe ngokwemvelo ngamaphrofayili;kufanele kube ngokushesha ngemva kokwelashwa kokugqwala kwe-asidi.Hlanza amanzi, futhi izinga lokushisa lokugeza amanzi lilawulwa ngaphambi kuka-50 °C ukugwema izimpawu zokugeleza ebusweni bephrofayili, bese uhlanza ngamanzi agelezayo.Njengoba iphrofayili ye-aluminium iqukethe i-copper element, indawo engaphezulu iba mnyama ngemva kokugqwala kwe-asidi, futhi idinga ukucwiliswa kusisombululo se-nitric acid imizuzu engu-3-5 ukuze wenze ubuso besiliva obukhanyayo.
④Inqubo yokufaka i-alkaline yamaphrofayela e-aluminium:
Inhloso eyinhloko yenqubo yokuhlanganisa i-alkali yamaphrofayili e-aluminium icishe ifane nenqubo yokuhlanganisa i-asidi, ukususa izinto ezisele kanye nezingqimba ze-metamorphic ebusweni bamaphrofayili e-aluminium ngesikhathi senqubo ye-oxidation, kanye nokuqeda ukukhubazeka kokubhala okusele ingaphezulu lamaphrofayili e-aluminium ngesikhathi senqubo yokukhipha;Ukwelashwa kwe-alkali etching surface kudlala indima ebalulekile kwikhwalithi iyonke yephrofayili ye-aluminium.
⑤Inqubo yokwenza iphrofayili ye-Aluminum ingathathi hlangothi:
Inhloso yenqubo yokungathathi hlangothi kwephrofayili ye-aluminium ukususa ithusi, i-manganese, insimbi, i-silicon nezinye izakhi ze-alloy noma ukungcola okuhlala phezu kwephrofayili ye-aluminium ngemva kokucwiliswa kwe-asidi kanye nokwelashwa kwe-alkali etching, okungancibiliki kusisombululo se-alkali, futhi nciphisa iphrofayili ye-aluminium.I-lye esele ngemva kokwelashwa kwe-alkaline etching ngokuvamile isetshenziselwa ukusebenzisa isisombululo se-nitric acid engu-30-50%.Ukuze uthole ama-alloys e-silicon ephezulu e-aluminium, phonsa kuma-alloys, usebenzisa ingxube ye-nitric acid ne-hydrogen fluoride ngesilinganiso sevolumu esingu-1:3.I-silicon ihlangana ne-hydrogen ne-hydrofluoric acid yakhe i-fluorosilicic acid futhi ishiye indawo ye-aluminium.
⑥Ukwelashwa kwe-anodizing kwamaphrofayili e-aluminium:
Indlela ye-anodizing iphrofayili ye-aluminium iwukusebenzisa isixazululo njenge-medium, futhi usebenzise ukukhishwa kwephuzu ukuze wenze ifilimu ye-oxide ebusweni bephrofayili ye-aluminium, ukuze iphrofayili ye-aluminium ibe nokumelana nokugqwala okukhulu, ngenxa yongqimba oluvikelayo olutholiwe. ngephrofayili ye-aluminium anodized Inokuqina okuphezulu nokumelana nokugqwala, futhi ukushuba okujwayelekile kungu-10-12μ, okungathuthukisa kangcono ukumelana ne-oxidation yamaphrofayili e-aluminium futhi kuthuthukise ubuhle bamaphrofayili.
I-Sulfuric acid anodization ivamise ukusebenzisa i-10-20% H2SO4 njenge-electrolyte, izinga lokushisa elisebenzayo lingu-15-20 ℃, ukuminyana kwamanje ngu-1-2.5A/dm2, futhi isikhathi se-electrolysis sincike ezidingweni zokujiya ifilimu, ngokuvamile ngu-20-60min.Umthombo wamandla ovame kakhulu ugesi oqondile.I-voltage esetshenzisiwe iyahlukahluka kuye ngokuthi i-conductivity, izinga lokushisa kanye nokuqukethwe kwe-aluminium ye-electrolyte.Ngokuvamile, i-15-20V.Imingcele yenqubo inomthelela omkhulu ekusebenzeni kwe-membrane.
⑦ Ukwelashwa kokuvala indawo yephrofayela ye-aluminium:
Ngemuva kokuthi iphrofayili ye-aluminium i-anodized, ama-micropores azokwakhiwa phezulu, okulula uku-oxidized futhi agqwaliswe ngesikhathi sokusetshenziswa.Ukwelashwa kokubeka uphawu kufanele kwenziwe ngemuva kokwelashwa kwe-anodizing.Inqubo yembobo isuka eYurophu), i-sulfuric acid anodizing ngokuvamile isebenzisa i-10-20% H2SO4 njenge-electrolyte, izinga lokushisa elisebenzayo liyi-15-20 ℃, ukuminyana kwamanje ngu-1-2.5A/dm2, isikhathi se-electrolysis sincike ekugqineni kwefilimu. izidingo, ngokuvamile ku-20- 60min.Umthombo wamandla ovame kakhulu ugesi oqondile.I-voltage esetshenzisiwe iyahlukahluka kuye ngokuthi i-conductivity, izinga lokushisa kanye nokuqukethwe kwe-aluminium ye-electrolyte.Ngokuvamile, i-15-20V.Imingcele yenqubo inomthelela omkhulu ekusebenzeni kwe-membrane.
