Titaniyamu plating ndondomeko golide kwa mbiri aluminiyamu ndi ❖ kuyanika ukadaulo, zomwe zachokera ochiritsira titaniyamu plating ndondomeko ndi Kuwonjezera masitepe chisanadze plating ndi electroplating ndondomeko, ndi ndondomeko aluminiyamu mbiri ndi kuika adamulowetsa yokutidwa mbali mu njira amadzimadzi. mchere ndi hydrochloric acid mankhwala mankhwala;The plating njira zikuchokera plating ndondomeko plating zikuphatikizapo faifi tambala sulphate, faifi tambala kolorayidi, asidi boric, sodium dodecyl sulfate, saccharin, ndi brightener, etc. Njira imeneyi ali ndi ubwino yosavuta, zothandiza ndi zotsatira zabwino.Kuuma kwa filimu ya titaniyamu mbiri ya aluminiyamu yopangidwa ndi njirayi ndi HV≈1500, nthawi 150 yosamva kuvala kuposa 22K plating ya golide pansi pazikhalidwe zomwezo, ndipo imatha kusinthidwa kukhala mitundu yosiyanasiyana ya golide, mtundu, wakuda ndi zina zowala za aluminiyamu. mbiri malonda.
Aluminiyamu imagawidwa mu aluminiyumu yaiwisi ndi aluminium yophika, aluminium yaiwisi ili pansi pa 98% ya aluminiyamu, chikhalidwe cha brittle ndi cholimba, chikhoza kutembenuza mchenga kuponya katundu;zotayidwa yophika ndi pamwamba 98% ya zotayidwa, chikhalidwe zofewa, akhoza calendered kapena adagulung'undisa ziwiya zosiyanasiyana.Mbiri ya aluminiyamu yotsika kwambiri imachepetsa kwambiri nthawi yotseka komanso kutaya kwa reagent yamankhwala, ngakhale kuti mtengowo umachepetsedwa, koma kukana kwa dzimbiri kwa mbiriyo kumachepetsedwa kwambiri.Ndiye poyitanitsa mbiri ya aluminiyamu, mungadziwe bwanji ngati ili yotsika?
Zowonongeka za Extrusion.The extrusion ndondomeko aluminiyamu mbiri adzabala zilema monga thovu, inclusions, wosanjikiza mapangidwe, kusiyana mtundu, kupotoza ndi zina zotero, zomwe zingakhudze khalidwe la aluminiyamu mbiri chifukwa cha kukwanira kwa zida extrusion, kukhwima kwa ndondomeko extrusion ndi ntchito yolakwika.
Chikoka cha kupanga mapangidwe pa khalidwe la aluminiyamu mbiri n'zofika patali kwambiri, amene makamaka zimaonekera mu zipangizo kupanga, nkhungu, zikhalidwe ntchito ndi ukalamba;kuti tidziwe ngati kutulutsa kwambiri kumakwaniritsa zofunikira, titha kuyambira pakuwoneka bwino, kulondola komanso mphamvu, ndikugwiritsa ntchito zida zamaluso kuti tiwone ngati mawonekedwe amtunduwo ndi athyathyathya, ngati pali peel lalanje kapena ming'alu, kaya kuwongoka kwa mbiri ndi oyenerera, etc.;za mphamvu ya mbiri, tiyenera kuyesa iwo mothandizidwa ndi zipangizo akatswiri.Mphamvu ndi kulimba kwa mbiri imodzi.
Makulidwe a filimu ya okusayidi ndi yoonda.Muyezo wa dziko la China ukunena kuti makulidwe a filimu ya oxide ya mbiri ya aluminiyamu yomanga sayenera kuchepera 10um (micron).Makulidwe sikokwanira, pamwamba pa zotayidwa mbiri n'zosavuta dzimbiri ndi dzimbiri.Zina mwambiri za aluminiyamu popanda dzina lopanga, adilesi ya fakitale, chilolezo chopanga ndi satifiketi yovomerezeka pakuwunika mwachisawawa, makulidwe a filimu ya oxide ndi 2 mpaka 4um, ndipo ena alibe filimu ya okusayidi.Malinga ndi kuyerekezera kwa akatswiri, kuchepetsa makulidwe a filimu ya 1um oxide iliyonse, mbiri iliyonse imatha kuchepetsa mtengo wogwiritsa ntchito magetsi ndi yuan yopitilira 150.
Zida za 6063 mndandanda wa aluminiyumu zimakhala ndi aluminiyamu-magnesium aloyi, koma pofuna kupititsa patsogolo mphamvu ya mbiri, zinthu zina zachitsulo zimawonjezeredwa ku aloyi kuti apange chiŵerengero chabwino cha zinthu zachitsulo, zomwe timazitcha kuti chiŵerengero chokhazikika;zopangira zosungunuka ndi kuponyedwa molingana ndi chiŵerengero chokhazikika zimatchedwa ndodo zoyamba za aluminiyamu, ndipo zolemba zowonjezera zimakhala ndi mphamvu zambiri komanso zokhazikika;komabe, pofuna kuchepetsa mtengo, mabizinesi ambiri amagwiritsa ntchito zida zachiwiri kapena zosinthidwa mobwerezabwereza.Komabe, pofuna kuchepetsa mtengo, mabizinesi ambiri amagwiritsa ntchito yachiwiri kapena mobwerezabwereza zobwezerezedwanso zotayidwa ndodo zotayidwa extrude zitsulo zotayidwa ndodo, ndi aloyi zikuchokera chiŵerengero cha mbiri opangidwa si yunifolomu, ndipo ambiri waikamo zonyansa ndi osakaniza, kotero khalidwe la mbiri sizotsimikizika.
Kapangidwe ka mankhwala si koyenera.Aluminiyamu mbiri wothira kuchuluka kwa zotayidwa zosiyanasiyana, zotayidwa zotayidwa akhoza kwambiri kuchepetsa mtengo, koma zidzatsogolera osayenera mankhwala zikuchokera mbiri aluminiyamu yomanga, amene adzaika pangozi chitetezo cha ntchito yomanga.Osayenerera mbiri zotayidwa, ntchito mpweya, mvula, kuwala kwa dzuwa ndi zina, chifukwa mapindikidwe mbiri aluminiyamu, ndipo ngakhale mapangidwe galasi akulimbana, kugwa ndi maonekedwe ena.
Kuchokera kuzinthu zakuthupi, mtundu wamtundu wa aluminiyumu wotulutsidwa ndi galasi loyambirira la aluminiyamu ndi loyera, ndipo pamwamba pazithunzi zomwe zili ndizitsulo zotsika kwambiri za aluminiyamu zimakhala zakuda, kotero kuti zopangirazo zikhoza kuweruzidwa ngati zabwino kapena zoipa.
Pamawonekedwe, mawonekedwe a aluminiyamu wamba amangokhala oyera-oxidized oxidized, ndipo mizere yotambasuka yomwe imapangidwa pamwamba pa ma profayilo panthawi ya extrusion ndiyowoneka bwino;pomwe ma profiles okhazikika amayenera kupakidwa mchenga pamaso pa oxidation kuti achotse mizere yotambasula pamwamba pa mbiriyo ndikuwonjezera kuchulukana kwambiri, zomwe zitha kukulitsa kukana kwa dzimbiri pamwamba pa mbiriyo, ndipo zotsatira zake zimakhala zokongola.
Anthu ambiri nthawi zambiri amatenga mtengo ngati chitsimikiziro pogula mbiri ya aluminiyamu, njira yogulitsira yotereyi imakhala ya mbali imodzi, chifukwa mbiri zambiri zimakhala ndi mawonekedwe omwewo, koma zinthu zomwe zimapangidwa, njira ndi kulemera kwake ndizosiyana kwambiri, ngati tingoyang'ana mtengo, ndiye kuti n'zosavuta kusokeretsedwa, kotero posankha mankhwala tiyenera kuganizira zakuthupi, ndondomeko ndi maonekedwe, etc. Kuti mudziwe zambiri, funsani Yutwin kasitomala kuti mudziwe zambiri, ndife okondwa kuyankha mafunso anu okhudza aluminiyamu.
