①Kupaka utoto wamtundu umodzi: Miwiritsani nthawi yomweyo zinthu za aluminiyamu mutatha kudzoza ndikusamba ndi madzi munjira yopaka utoto pa 40-60 ℃.Kuwuka nthawi: 30 masekondi-3 mphindi kuwala mitundu;Mphindi 3-10 kwa mitundu yakuda ndi yakuda.Mukataya utoto, itulutseni ndikusamba ndi madzi oyera.
②Kupaka utoto wamitundu yambiri: Ngati mitundu iwiri kapena kupitilira apo idayidwa pa aluminiyamu yomweyi, kapena malo, maluwa ndi mbalame, zithunzi, ndi zilembo zikasindikizidwa, njirazo ndizovuta kwambiri, monga njira yopaka utoto, kusindikiza mwachindunji ndi njira yopaka utoto, pulasitiki ya thovu Njira yopaka utoto, etc. Njira zomwe zili pamwambazi zimagwira ntchito mosiyana, koma mfundo zake ndi zofanana.Tsopano njira yopaka utoto imayambitsidwa motere: Njirayi makamaka ndiyo kugwiritsa ntchito vanishi wowuma mwachangu komanso wosavuta kuyeretsa pang'onopang'ono komanso wofanana pachikasu chomwe chikufunika kwambiri kuti chiphimbe.Pambuyo filimu ya penti yowuma, ikani zigawo za aluminiyamu mu njira yothetsera chromic acid kuti muchotse mtundu wachikasu wa gawo losapentidwa, mutulutse, mutsuka madzi a asidi ndi madzi, muwumitse kutentha pang'ono, ndiyeno mupaka utoto wofiira., Mitundu inayi imatha kuyendetsedwa molingana ndi njira yomwe ili pamwambapa.
Tsekani: Zigawo zotayidwa za aluminiyamu zitatsukidwa ndi madzi, zimayikidwa nthawi yomweyo m'madzi osungunuka a 90-100 ℃ ndikuphika kwa mphindi 30.Pambuyo pa mankhwalawa, pamwamba pamakhala yunifolomu komanso yopanda porous, ndikupanga filimu yowonjezereka ya okusayidi.Utoto wokutidwa ndi utotowo umayikidwa mufilimu ya oxide ndipo sungathenso kufufutidwa.Filimu ya oxide itatha kutsekedwa sikhalanso adsorbable, ndipo kukana kuvala, kukana kutentha ndi katundu wotsekemera kumawonjezeka.
Ziumitsa pamwamba pa mbali zotayidwa kuchitiridwa ndi kutseka, ndiyeno kupukuta ndi nsalu yofewa, mukhoza kupeza zokongola ndi zokongola zotayidwa zinthu, monga utoto Mipikisano mitundu, pambuyo kutseka mankhwala, woteteza ntchito pa mbali zotayidwa ayenera. kuchotsedwa.Madera ang'onoang'ono amatha kufafanizidwa ndi thonje woviikidwa mu acetone, ndipo madera akulu amatha kutsukidwa pomiza mbali zopaka utoto za aluminiyamu mu acetone.
