Pansi pa electrolyte yofanana ndi momwe zinthu zilili, aluminiyamu ndi zitsulo zake zimapanga filimu ya oxide pa chinthu cha aluminiyamu (anode) chifukwa cha mphamvu yamagetsi yomwe imagwiritsidwa ntchito. Cholinga chake ndikuthana ndi zolakwika za kuuma kwa pamwamba ndi kukana kwa aloyi ya aluminiyamu, kukulitsa kuchuluka kwa ntchito ndikuwonjezera moyo wa ntchito.
Kodi anode ndi chiyani?
Mu batire ya mankhwala, electrode yomwe imatha kupangitsa kuti electrolyte ikhale yosungunuka imatchedwa anode.
Pali mitundu yambiri ya mayankho omwe amagwiritsidwa ntchito popaka mafuta. Pakadali pano omwe amagwiritsidwa ntchito kwambiri ndi sulfuric acid, oxalic acid, malonic acid, sulfonic acid ndi zina zotero. Chodziwika kwambiri mwa izi ndi kugwiritsa ntchito sulfuric acid ngati njira yothetsera oxidative. Ubwino wake ndi wakuti filimu yokhuthala ya oxide ingapezeke, porosity ya filimu ya oxide nayonso ndi yayikulu, chodzaza chikhoza kunyowa bwino, pali mitundu yambiri ndi mafotokozedwe a zinthu zogwiritsidwa ntchito za aluminiyamu, ukadaulo wogwirira ntchito si wovuta, ndipo mphamvu yogwiritsidwa ntchito ndi yochepa.
Chifukwa chiyani zida za aluminiyamu zimasinthidwa kukhala anodized?
1. Chivundikiro cha njira yopangira makina.
Pambuyo pa CNC machining, nthawi zambiri pamakhala mizere ya zida pamwamba pa zida za aluminiyamu. Ngati makasitomala akufuna kukonza "mawonekedwe" a zida za aluminiyamu, ambiri a iwo amasankha kugwiritsa ntchito sandblasting + anode pokonza pamwamba.
2. Kuwongolera kukana dzimbiri.
Ndipotu, aluminiyamu yopangidwa ndi aluminiyamu ndi chitsulo chosagwira dzimbiri chifukwa aluminiyamu imagwira ntchito kwambiri ndipo imakonda kuchita zinthu zosiyanasiyana ndi mpweya womwe uli mumlengalenga kuti ipange aluminiyamu oxide. Filimu yowonekera bwino ya aluminiyamu oxide siioneka ndi maso a munthu. Filimu yopyapyala ya aluminiyamu oxide iyi imangolekanitsa mpweya kuti chinthu chopangidwa ndi aluminiyamu chisawonongeke. Filimu ya oxide yomwe imapezeka mwachilengedwe imagwira ntchito ngati anti-oxidant.
3. Kulimbitsa kukana kuvala.
Aluminiyamu imakonda kukanda ndi kutha, ndipo kuuma kwa aluminiyamu sikungafanane ndi chitsulo. Pamwamba pa aluminiyamu yopangidwa ndi mafakitale ndi yolimba kwambiri, ndipo kuuma kwa filimu ya oxide kumafika pa 300HV. Chifukwa chake, ndi yolimba kwambiri ndipo siivuta kukanda.
4. Kupaka utoto pamwamba pa zinthu zokongoletsera za aluminiyamu.
Asanalowetse ndi kutseka aluminiyamu, pamakhala ma pores ambiri okhuthala pamwamba, omwe ndi osavuta kuyamwa mchere ndi utoto wachitsulo, ndipo pamwamba pa zinthu zopangidwa ndi aluminiyamu pamapanga mitundu yosiyanasiyana.
5. Konzani kutchinjiriza.
Aluminiyamu imagwira ntchito bwino kwambiri ndi magetsi, koma aluminiyamu imafuna kutenthetsa nthawi zina. Filimu ya aluminiyamu yosakanizidwa siigwira ntchito.
6. Ikani utoto pamwamba.
Malo ena a aluminiyamu amafunika kupakidwa utoto. Pamwamba pa aluminiyamu yodzozedwayo pali madzi amphamvu, ndipo utoto wake ndi wofanana komanso wokongola.
Kukhuthala kwa filimu yonse ya anodizing ya dziko lonse ndi ma microns 10-20.
Chifukwa chiyani anodizing ndi yofunika?
Kumbali imodzi, chifukwa cha filimu yosafanana ya oxide yomwe imapangidwa mwachilengedwe, mtundu wa pamwamba pa aluminiyamu ndi wosiyana komanso wosakongola.
Kumbali inayi, filimu ya oxide yopangidwa mwachilengedwe ndi yopyapyala, yosavuta kuwonongeka, komanso yofooka chifukwa cha kukana dzimbiri. Filimu ya oxide yopangidwa ndi anodic oxidation ndi yofanana, yokhuthala komanso yolimba ku mafuta a dzimbiri.
