Zvikonzero zviri kumashure kwemavara asina kuenzana ealuminium alloy oxide firimu

Zvitatu zvinogona kukonzera aluminium mbiri oxide firimu ruvara haina yunifomu:

(1) Kana iyo aluminiyamu profil inodized, pane zvakakosha mutsauko munzvimbo yeworkpiece, slot swing range, kumucheto uye nzvimbo yepakati, kugadzirisa kugadzirisa, kugadzirisa, uye kuchinjana, izvo zvinotungamira kune isina kuenzana ruvara firimu. Matanho ekudzivirira anosanganisira diki swing renji uchidzora iyo aluminiyamu mbiri uye pamwe static kurapwa, kunyangwe yakanyanya-yakadzika mhinduro tembiricha inogona kukonzera kuumbwa kwemepu kana mavara, izvo zvisiri izvo zvinotarisirwa.

(2) Kana zvikamu zvealuminium zvakavharwa zvaparadzwa, nekucheka, kunze kwealclad ndeyemhando yepamusoro yealuminium, yakavharwa mukati memukati yakasiyana-siyana yealuminiyamu, maviri aruminiyamu akasiyana, saka oxidation mushure me "benign vitiligo" semavara. Mutengi kazhinji haanyatso nzwisisa nezve chiitiko ichi, vagadziri vanofanira kuita zvakawanda kutsanangura basa, kutsanangura kuti sei uye sei, kuitira kudzivirira kusanzwisisa.

(3) Nyaya dzine chekuita nekushanda

Kwete tsvina yose yakabviswa nefirimu yepakutanga yemunharaunda uye workpiece's caustic treatment yakanga isina kukwana;

Iyo yepamusoro ichiri yakakosha mushure me alkali etching sezvo mwenje wekugadzirisa hausi kuiswa ipapo ipapo;

kupindirana kweiyo workpiece panguva yekufambisa nezvinhu zvekunze.

Kana vhidhiyo ikaratidza ruvara rusingawirirane, chiito chakakodzera chinofanira kuitwa kugadzirisa nyaya kubva kumakona akawanda.

Mhosva muverengi anodana achibvunza workpiece mushure me alkali etching conductive oxide firimu zvakaoma kuwana zvikonzero zvinokonzerwa nealkaline etching liquid aluminium ion accumulation yakawandisa, mushure mekuregererwa kwezvinhu zvakawanda uye zvakaoma kuumba conductive oxide film, tora mukati. account kana iyo yakakwira aruminiyamu ion alkali etching solution, imwe yacho yakati alkaline corrosion solution yakakora kwazvo. Asi iyo alkali corrosion speed haina kukurumidza. Ipapo munyori anoratidza kushandura alkaline corrosion solution, nekuti mushure me alkaline etching liquid yakashandiswa kwenguva yakareba ichaita aruminiyamu ion kuunganidza yakawandisa, aluminium ion pamusoro peiyo workpiece yakaoma kuburitsa, nekudaro inokanganisa iyo aluminium pamusoro uye conductive oxide mhinduro kusangana, nokudaro kukanganisa kuumbwa kwe oxide film. Imwe pfungwa ndeyokuti kana unconditional kutsiva alkaline etching mhinduro, workpiece pashure alkali etching pashure pemvura sukurudza pakarepo pashure kuyerera kwemvura sukurudza, uye ipapo chiedza ari hydrofluoric asidhi ine concentrated nitric acid, ipapo sukurudza kwazvo pashure kuitisa oxidation kurapwa. Mushure mekunge vaverengi vafonera vakati mushure me alkali etching nemvura inopisa uye mhedzisiro yacho yakanaka kwazvo. Munyori ndiye ruzivo, uye mumvura inopisa mushure memvura inopisa uye pakarepo kunyudzwa mumvura nokukurumidza kusiya, kudzivirira workpiece nekuoma nokuda oxidation uye kukanganisa paumbwe conductive oxide firimu.
