Imboni yephrofayili ye-aluminium yezimboni yaseChongqing ithuthuke ngokushesha eminyakeni yamuva nje, futhi kancane kancane ibhekane nezwe lonke. Ubuchwepheshe be-anodizing bungenye yezindlela ezisetshenziswa kakhulu embonini yephrofayili ye-aluminium yezimboni yaseChongqing. Abasebenzisi abaningi abasha abazi okuningi ngenqubo ye-anodizing, ngakho-ke ake sikunikeze isingeniso esinemininingwane.
Ukugeleza kwenqubo yokwelashwa kwe-oxidation kwamaphrofayili e-aluminium ezimbonini eChongqing;
1. Ukwelashwa kwendawo.
Ukwelashwa kwendawo, okwaziwa nangokuthi ukwelashwa kwangaphambili kwendawo, ukususa ukungcola ebusweni bephrofayili ye-aluminium ngokusebenzisa izinto ezibonakalayo nezamakhemikhali, ukuze kuvezwe emzimbeni wephrofayili ye-aluminium, okulula ukwelashwa nge-oxidation ebusweni bephrofayili ye-aluminium esigabeni esilandelayo.
2. Inqubo yokususa amafutha ebusweni.
Inhloso yenqubo yokususa amafutha ukususa izinto zokugcoba zezimboni, uwoyela ovimbela ukugqwala kanye nokungcola okunamathiselwe ebusweni bephrofayili ye-aluminium, ukuqinisekisa ukugqwala okufanayo kwephrofayili ye-aluminium kanye nokuhlanzeka kwethangi lokugqwala kwe-alkali. Thuthukisa ikhwalithi yokwelashwa kwendawo yephrofayili ye-aluminium.
3. Inqubo yokuqopha i-asidi.
Inqubo yokuqopha i-surface acid iwukwenza ukwelashwa kokuqopha i-surface acid ngemva kokususa amafutha kuphrofayili ye-aluminium, futhi inhloso eyinhloko yokususa ukususa i-oxide eyakhiwe yi-oxidation yezinye izakhi zensimbi ebusweni bephrofayili ye-aluminium kanye nefilimu ye-oxide eyakhiwe ngokwemvelo yiphrofayili; Ngemva kokwelashwa kokuqopha i-acid, kuyadingeka ukuyigeza ngokushesha, futhi izinga lokushisa lokuwasha kufanele lilawulwe ngaphambi kuka-50℃ ukuze kugwenywe amamaki okugeleza ebusweni bephrofayili, bese uyihlanza ngamanzi agobhozayo. Ngenxa yokuthi iphrofayili ye-aluminium iqukethe ithusi, ubuso buba mnyama ngemva kokuhlolwa kokuqopha i-acid, futhi kudingeka bufakwe emanzini esisombululo se-nitric acid imizuzu emi-3-5 ukuze ubuso bube yisiliva elikhanyayo.
4. Inqubo yokuqopha i-alkaline.
Inhloso eyinhloko yenqubo yokuqopha i-alkali ukususa izinto ezisele kanye nezendlalelo eziguqukile ebusweni bephrofayili ye-aluminiyamu ngesikhathi sokushiswa kwe-oxidation, kanye nokususa amaphutha okuklwebheka asele ebusweni bephrofayili ye-aluminiyamu ngesikhathi sokuxova. Ukwelashwa kokuqopha i-alkaline ebusweni bephrofayili ye-aluminiyamu kudlala indima ebalulekile ekhwalithini iyonke yobuso bephrofayili ye-aluminiyamu.
5. Inqubo yokungathathi hlangothi.
Inhloso yenqubo yokungaguquguquki ukususa izinto ezixubile noma ukungcola okufana nethusi, i-manganese, insimbi, i-silicon, njll. okungancibiliki kwisisombululo se-alkaline esisele ebusweni bephrofayili ye-aluminium ngemva kokuchoboza i-asidi kanye nokuchoboza i-alkali. Ngokuvamile, indlela yokungaguquguquki kwesisombululo se-alkaline esisele kuphrofayili ye-aluminium ngemva kokuchoboza i-alkali ukusebenzisa isisombululo se-nitric acid esingu-30%-50%. Ukuze uthole i-aluminium alloy ene-silicon ephezulu, kukhethwa i-asidi exubile ye-nitric acid kanye ne-hydrogen fluoride enesilinganiso sevolumu esingu-1: 3. I-Silicon isabela ne-hydrogen kanye ne-hydrofluoric acid ukuze ikhiqize i-fluosilicic acid, eshiya ubuso be-aluminium.
6. Ukwelashwa kokufaka i-anodizing.
Indlela yokwelashwa kwe-anodic oxidation ukuthi ikhambi lisetshenziswa njengendlela yokuxhumana, bese kukhethwa ukukhishwa kwe-tip ukuze kwakheke ifilimu ye-oxide ebusweni bephrofayili ye-aluminium, ukuze iphrofayili ye-aluminium ibe nokumelana okukhulu kokugqwala. Ngenxa yokuthi ungqimba oluvikelayo olutholakala nge-anodic oxidation yephrofayili ye-aluminium lunobunzima obuphezulu kanye nokumelana nokugqwala, ubukhulu obujwayelekile bungu-10-12μ m, okungathuthukisa kangcono ukumelana kwe-oxidation yephrofayili ye-aluminium kanye nobuhle bephrofayili ye-aluminium.
Inqubo yokushiswa kwe-anodic idlala indima ebalulekile ebuhleni nasekuqineni kwamaphrofayili e-aluminium ezimbonini zaseChongqing.
