Mafotokozedwe Akatundu
Wopukutidwa mbiri zotayidwa, pamwamba kupukuta mbiri zotayidwa ndi yofunika processing luso mu zotayidwa mbiri processing, amene akhoza kusintha durability ndi aesthetics a zotayidwa mbiri mankhwala, potero kuonjezera mtengo ndi kukopa kwa zotayidwa mbiri mankhwala.
Kupukuta kwa mankhwala ndi electrochemical polishing ndi njira yomaliza yomaliza yomwe imatha kuchotsa mildew yaing'ono ndi zokopa pamwamba pa zinthu za aluminiyumu;onse angathe kuchotsa mikangano magulu, zigawo thermally olumala ndi anodizing kuti akhoza kupanga mu makina kupukuta filimu wosanjikiza.Pambuyo pa mankhwala kapena electrochemical kupukuta, pamwamba pa aluminiyamu workpieces akhakula amakhala yosalala ndi chonyezimira ngati galasi, amene bwino kukongoletsa zotsatira za zotayidwa katundu (monga kusinkhasinkha katundu, kuwala, etc.).Itha kuperekanso zinthu zamalonda zamtengo wapatali kwambiri kuti zikwaniritse kufunikira kwa zinthu za aluminiyamu zokhala ndi malo owala.Choncho, mankhwala kupukuta kapena electrochemical kupukuta chithandizo chofunika kukwaniritsa zofunika pamwamba pamwamba yosalala, yunifolomu ndi yowala.
Kupukuta kwa mankhwala ndi kupukuta kwa electrochemical kungapangitse pamwamba pa aluminiyamu kukhala yowala kwambiri, koma ponena za kupukuta, kupukuta kwa mankhwala (kapena electrochemical polishing) ndikosiyana kwambiri ndi kupukuta kwamakina:
Kupukuta kwamakina ndiko kugwiritsa ntchito zida zakuthupi kuti ziwononge aluminiyamu pamwamba podula ndikupera mwachangu, kukakamiza mbali zowoneka bwino zapamtunda kuti zidzaze mbali zopindika, potero kuchepetsa ndi kusalaza kuuma kwa mbiri ya aluminiyamu.Komabe, kupukuta kwamakina kumatha kuwononga chitsulo pamwamba pa crystallization, komanso kupanga zigawo za pulasitiki zopindika ndi kusintha kwa microstructure chifukwa cha kutentha komweko.
Chemical kupukuta ndi mtundu wa dzimbiri mankhwala pamikhalidwe yapadera.Njirayi ndikuwongolera kusungunuka kosankha, kotero kuti gawo lotukuka la pamwamba pa aluminiyumu limasungunuka pamaso pa malo opindika, ndipo pamapeto pake pamwamba pake ndi yosalala komanso yowala.
Njira ya electrochemical polishing, yomwe imadziwikanso kuti electropolishing, ndi yofanana ndi kupukuta kwa mankhwala chifukwa imatha kupanga malo osalala komanso owala poyang'anira kusungunuka kosankha.Malinga ndi mfundo ya electrochemical nsonga kumaliseche, mbiri zotayidwa kumizidwa mu electrolyte okonzeka monga anode, ndi zinthu dzimbiri zosagwira ndi madutsidwe wabwino kumizidwa mu cathode.
Mu kupanga mafakitale, cholinga chachikulu cha mankhwala kupukuta kapena electrochemical kupukuta ndi m'malo makina kupukuta kupeza yosalala ndi yowala pamwamba.Chachiwiri ndikugwiritsa ntchito kupukuta kwamankhwala kapena kupukuta kwa electrochemical kuti mupeze mawonekedwe apamwamba kwambiri komanso ochititsa chidwi a aluminiyamu ndi zida za aluminiyamu.
