Wopanga ma profile a aluminiyamu a ku Chongqing amakuuzani njira yopangira oxidation ya anodic.

Makampani opanga aluminiyamu m'mafakitale ku Chongqing apita patsogolo mofulumira m'zaka zaposachedwa, ndipo pang'onopang'ono akukumana ndi dziko lonselo. Ukadaulo wa anodizing ndi njira imodzi yomwe imagwiritsidwa ntchito kwambiri mumakampani opanga aluminiyamu m'mafakitale ku Chongqing. Ogwiritsa ntchito ambiri atsopano sadziwa zambiri za njira yopangira anodizing, choncho tiyeni tikupatseni chiyambi chatsatanetsatane.
Kuyenda kwa njira yochiritsira okosijeni pa ma profiles a aluminiyamu a mafakitale ku Chongqing;
1. Chithandizo cha pamwamba.
Kuchiza pamwamba, komwe kumadziwikanso kuti kukonzekera pamwamba, ndiko kuchotsa dothi pamwamba pa mbiri ya aluminiyamu pogwiritsa ntchito zinthu zakuthupi ndi zamankhwala, kuti liwonekere ku thupi la mbiri ya aluminiyamu, zomwe ndizosavuta kuchiza ndi okosijeni pamwamba pa mbiri ya aluminiyamu mtsogolo.
2. Njira yochotsera mafuta pamwamba.
Cholinga cha njira yochotsera mafuta ndikuchotsa mafuta odzola m'mafakitale, mafuta oletsa kuwononga ndi zinyalala zomwe zili pamwamba pa aluminiyamu, kuonetsetsa kuti aluminiyamu ikuwonongeka mofanana komanso kuti thanki ya aluminiyamu ikuyera. Kupititsa patsogolo ubwino wa pamwamba pa aluminiyamu.
3. Njira yocheka asidi.
Njira yochotsera asidi pamwamba ndikuchita chithandizo cha kuchotsera asidi pamwamba pambuyo pochotsa mafuta pa aluminiyamu, ndipo cholinga chachikulu chochotsera ndikuchotsa oxide yomwe imapangidwa ndi okosijeni wa zinthu zina zachitsulo pamwamba pa aluminiyamu ndi filimu ya oxide yomwe imapangidwa mwachilengedwe ndi mbiriyo; Pambuyo pochotsa asidi, ndikofunikira kuitsuka nthawi yomweyo, ndipo kutentha kwa kutsuka kuyenera kuyendetsedwa ndi 50℃ koyambirira kuti tipewe zizindikiro zoyenda pamwamba pa mbiriyo, kenako nkuiyeretsa ndi madzi othamanga. Chifukwa chakuti mbiri ya aluminiyamu ili ndi mkuwa, pamwamba pake pamakhala mdima pambuyo poyesa kuwononga asidi, ndipo pamafunika kunyowa mu nitric acid solution kwa mphindi 3-5 kuti pamwamba pake pakhale siliva wowala.
4. Njira yocheka zinthu za alkaline.
Cholinga chachikulu cha njira yopangira aluminiyamu ndi kuchotsa zinthu zotsalira ndi zigawo zomwe zasintha mawonekedwe ake pamwamba pa aluminiyamu panthawi ya okosijeni, komanso kuchotsa zolakwika zomwe zimatsala pamwamba pa aluminiyamu panthawi yokanda. Kukonza pamwamba pa aluminiyamu pogwiritsa ntchito alkaline kumachita gawo lofunikira kwambiri pa ubwino wonse wa pamwamba pa aluminiyamu.
5. Njira yochepetsera kufalikira kwa zinthu.
Cholinga cha njira yochepetsera zinthu ndikuchotsa zinthu zodetsedwa monga mkuwa, manganese, chitsulo, silicon, ndi zina zotero zomwe sizisungunuka mu yankho la alkaline lomwe latsala pamwamba pa mbiri ya aluminiyamu pambuyo pochotsa asidi ndi kupukuta alkali. Kawirikawiri, njira yochepetsera yankho la alkaline lomwe latsala pamwamba pa mbiri ya aluminiyamu pambuyo pochotsa asidi ndikugwiritsa ntchito yankho la nitric acid la 30%-50%. Pa aloyi ya aluminiyamu yokhala ndi silicon yambiri, asidi wosakaniza wa nitric acid ndi hydrogen fluoride wokhala ndi chiŵerengero cha voliyumu cha 1: 3 amasankhidwa. Silicon imayanjana ndi hydrogen ndi hydrofluoric acid kuti ipange fluosilicic acid, yomwe imachoka pamwamba pa aluminiyamu.
6. Chithandizo cha anodizing.
Njira yochizira anodic oxidation ndi yakuti yankho limagwiritsidwa ntchito ngati njira yolumikizira, ndipo kutuluka kwa nsonga kumasankhidwa kuti apange filimu ya oxide pamwamba pa aluminiyamu, kotero kuti aluminiyamuyo ikhale ndi kukana kwambiri dzimbiri. Chifukwa chakuti gawo loteteza lomwe limapezeka ndi anodic oxidation ya aluminiyamu lili ndi kuuma kwakukulu komanso kukana dzimbiri, makulidwe wamba ndi 10-12μ m, zomwe zingathandize bwino kukana kwa oxidation ya aluminiyamu komanso kukongola kwa aluminiyamu.
Njira yothira mafuta m'thupi imagwira ntchito yofunika kwambiri pakukongola ndi kulimba kwa ma profiles a aluminiyamu amakampani a Chongqing.
