Mbiri za aluminiyamu zimagwiritsidwa ntchito kwambiri pomanga, mayendedwe, ndi mafakitale ena chifukwa chakuchita bwino kwambiri potengera mphamvu, kulimba, komanso kutsika mtengo.Kupititsa patsogolo maonekedwe ndi kulimba kwa mbiri ya aluminiyamu, njira zosiyanasiyana zothandizira pamwamba zapangidwa.Nkhaniyi ifotokoza njira zinayi zochiritsira zodziwika bwino za aluminiyamu: kupopera mbewu mankhwalawa, oxidation, sandblasting, ndi electrophoresis.
Kupopera mbewu mankhwalawa
Kupopera mbewu mankhwalawa ndi njira yodziwika bwino yochizira ma profiles a aluminiyamu, yomwe imaphatikizapo kugwiritsa ntchito mfuti yopopera kuti agwiritse ntchito utoto kapena zokutira za ufa pamwamba pa mbiriyo.Utoto kapena zokutira za ufa sizingapereke mawonekedwe okongoletsera komanso chitetezo ku dzimbiri ndi kuvala.Ubwino wa zokutira umadalira mtundu wa utoto kapena ufa, njira yogwiritsira ntchito, ndi kukonzekera pamwamba.
Kuchuluka kwa okosijeni
Oxidation, yomwe imadziwikanso kuti anodizing, ndi njira yamankhwala yomwe gawo la aluminium oxide limapangidwa pamwamba pa mbiri kudzera mu electrolysis.Makulidwe ndi mtundu wa oxide wosanjikiza ukhoza kuwongoleredwa ndi nthawi ndi mphamvu ya njirayi.Wosanjikiza wa oxide amatha kukulitsa kukana kwa dzimbiri, kukana kuvala, komanso kulimba kwambiri kwambiri.Wosanjikiza wa oxide amathanso kusindikizidwa ndi organic kapena inorganic compounds kuti apititse patsogolo kulimba ndi mawonekedwe a mbiriyo.
Kuphulika kwa mchenga
Sandblasting ndi njira yamakina yomwe imaphatikizapo kugwiritsa ntchito ma abrasives kuyeretsa ndi kukwiyitsa pamwamba pa mbiri.Kuphulika kwa mchenga kumatha kuchotsa dothi, mafilimu a oxide, ndi zonyansa zina kuchokera pamwamba ndikupanga matte kapena mawonekedwe okhwima.Kuphulika kwa mchenga kumathandizanso kumamatira kwa zokutira ndikuwongolera kufalikira kwambiri.Mtundu ndi kukula kwa abrasives, kuthamanga ndi mtunda wa nozzle, ndi nthawi ya ndondomekoyi zingakhudze ubwino ndi kusasinthasintha kwa pamwamba.
Electrophoresis
Electrophoresis, yomwe imadziwikanso kuti electrocoating, ndi njira yogwiritsira ntchito penti kapena primer ku mbiri ya aluminiyamu pogwiritsa ntchito mphamvu yamagetsi kuyika zokutira pamwamba.Njirayi imaphatikizapo kumiza ma profailo posambira kwa utoto kapena koyambira ndikuyika kusiyana kwamagetsi pakati pa mbiri ndi ma electrode mukusamba.Chophimbacho chikhoza kupanga yunifolomu ndi yopyapyala pamwamba, ndi kumamatira bwino, kuphimba, ndi kukana dzimbiri.Electrophoresis imathanso kuchepetsa kuwonongeka kwa chilengedwe cha ntchito zokutira pochepetsa kuwonongeka kwa utoto ndi zosungunulira.
Mapeto
Pomaliza, chithandizo chapamwamba cha mbiri ya aluminiyamu chimatha kukhudza kwambiri mawonekedwe, magwiridwe antchito, komanso kulimba kwawo.Chisankho cha njira yochizira pamwamba chikuyenera kuganizira zofunikira pakugwiritsa ntchito, monga kukumana ndi nyengo, mankhwala, kapena kupsinjika kwamakina.Njira zosiyanasiyana zochizira pamwamba zimatha kuthandizirana kuti mukwaniritse zotsatira zomwe mukufuna.Makampani opanga chithandizo chapamwamba akupitiliza kupanga zatsopano ndikupita patsogolo kuti akwaniritse zosowa za makasitomala ndi chilengedwe.
