Kungani uchungechunge olungu-7 uchungechunge lwe-aluminium lunzima ku-oxidize?

I-7075 Aluminium Alloy, njenge-Aluminium Alloy e-Aluminium e-7 Kodwa-ke, kukhona ezinye izinselelo lapho wenza ukwelashwa komhlaba, ikakhulukazi lapho wenza anonizing ukuthuthukisa ukumelana kwawo kokugqwala nobulukhuni bendawo.

I-Anodizing inqubo ye-electrochemical lapho i-aluminium oxide ifilimu ingakhiwa khona entweni yensimbi ukuze ithuthukise ukumelana kwayo, ukumelana nokugqwala kanye nama-aesthetics. Kodwa-ke, ngenxa yokuqukethwe okuphezulu kwe-zinc ku-7075 aluminium alloy kanye nezici zokwakheka kwe-Al-Zn-Mg Alloy, ezinye izinkinga zithambekele ekwenzeni i-anodizing:

1. Umbala ongalingani:I-zinc element inomthelela omkhulu emphumeleni we-oxidation, okungaholela kalula emaphethelweni amhlophe, izindawo ezimnyama, nemibala engalingani emsebenzini we-workpiece ngemuva kwe-oxidation. Lezi zinkinga zibonakala ikakhulukazi lapho zizama ukukwenza i-oxidize zibe yimibala ekhanyayo (efana nebomvu, i-orange, njll.) Ngoba ukuqina kwale mibala kumpofu.

2. Ukunamathela okunganele kwefilimu ye-oxide:Lapho inqubo yendabuko ye-sulfuric acid anodizing isetshenziselwa ukwelapha ama-aluminium ama-aluminium angu-7, ngenxa yokusatshalaliswa okungalingani kanye nokuhlukaniswa kwezakhi ze-aluminium alloy, usayizi we-micropores ebusweni befilimu le-oxide azohluka kakhulu ngemuva kokufaka anodizing. Lokhu kuholela umehluko kwikhwalithi kanye nokunamathela kwefilimu exide ezindaweni ezahlukene, futhi ifilimu ye-oxide kwezinye izindawo inokunamathela okubuthakathaka futhi kungaze kwehle.

Ukuze uxazulule lezi zinkinga, kuyadingeka ukwamukela inqubo ekhethekile yokungenisa i-anodizing noma ukuthuthukisa inqubo ekhona, njengokushintsha ukwakheka, izinga lokushisa kanye nobuningi bamanje be-electrolyte, okuzothinta ikhwalithi nokusebenza kwefilimu le-oxide. Isibonelo, i-PH ye-electrolyte izokuthinta izinga lokukhula kanye nesakhiwo se-pore yefilimu ye-oxide; Ukuqina kwamanje kuhlobene ngqo nobunzima nobulukhuni befilimu ye-oxide. Ngokulawula ngokuqondile la mapharamitha, ifilimu ye-aluminium ehlangana nezidingo ezithile ingenziwa ngokwezifiso.

Izivivinyo zikhombisa ukuthi ngemuva kokufaka i-anodizing aluminium alluminium aluminium alloy, i-oxide ifilimu enobukhulu be-30um-50um ingatholwa. Le filimu ye-oxide ayikwazi ukuvikela kuphela i-aluminium alloy substrate futhi yandise impilo yayo yenkonzo, kodwa futhi ihlangabezana nezidingo ezithile zokusebenza ngokulungisa amapharamitha enqubo. Ingaphezulu le-Aluminium Alloy ngemuva kokufaka i-anodizing nayo ingadaywe ukuze idonse imibala ye-organic noma engahloli ukunikeza imibala ecebile ye-aluminium alloy ukuze ihlangabezane nezidingo ezahlukahlukene zobuhle.

Kafushane, Ukungenisa i-anoding kuyindlela ephumelelayo yokwenza ngcono ukusebenza kwama-alloys we-aluminium angu-7. Ngokushintsha amapharamitha enqubo, ifilimu evikelayo ehlangabezana nobulukhuni obuthile nezidingo zobukhulu zingalungiswa, okunwebeka kakhulu insimu yesicelo yama-aluminium alloys.
