Emikhakheni yokuhlobisa izakhiwo kanye nokukhiqiza izimboni, amakhoyili e-aluminium anemibala aseba yindlela ekhethwayo kunezinto zendabuko ngenxa yokusebenza kwawo okuhle kakhulu kanye nezinhlobo ezahlukahlukene. Lolu hlobo lwekhoyili, olusekelwe ku-aluminium alloy futhi luphathwe ngombala wobuso kanye nopende, lugcina izinzuzo ezingokwemvelo ze-aluminium.—elula futhi evikela ukugqwala—ngenkathi futhi inikwe ubuhle obuhle kanye nokusebenza ngokucutshungulwa, okwenza isetshenziswe kabanzi emikhakheni eyahlukahlukene.
Izinto eziyisisekelo zamakhoyili e-aluminium anemibala ikakhulukazi ama-alloy e-aluminium anochungechunge olu-1, uchungechunge olu-3, kanye nochungechunge olu-5. Umehluko ezicini zochungechunge oluhlukene lwezinto eziyisisekelo uthinta ngqo izimo ezifanele:
I-aluminium emsulwa yochungechunge olulodwa (ngokuvamile i-1060): Inqubo yokukhiqiza elula, intengo ephansi, kodwa izinto zithambile, zifanele izimo ezijwayelekile ezinezidingo zamandla aphansi (njengokugquma amapayipi, amabhodi okukhangisa), okunikeza ukusebenza kahle kakhulu kwezindleko.
Ama-alloy e-aluminium-manganese anguchungechunge olu-3 (ngokuvamile angu-3003/3004): I-3003 iqukethe i-manganese engu-1.0-1.5%, enikeza ukumelana okuhle nokugqwala. Ubulukhuni bayo kanye namandla ayo okunamathela kuphakeme kune-alloy yochungechunge olu-1, okwenza kube yinto eyisisekelo esetshenziswa kakhulu. I-3004 iqukethe i-magnesium eyengeziwe engu-0.8-1.3% (eyaziwa nangokuthi i-aluminium-magnesium-manganese alloy), okuholela ekuqineni okuphezulu kanye nokufaneleka kokwakha uphahla olunezidingo eziphezulu zamandla esakhiwo. Intengo yayo iphakeme kancane kune-3003.
Ama-alloy e-aluminium-magnesium anguchungechunge olu-5 (ngokuvamile angu-5052): Aqukethe i-magnesium engu-3-5%, lawa ma-alloy anobunzima obuphansi, amandla aphezulu okuthambekela, futhi alula. Abiza kakhulu futhi ngezinye izikhathi asetshenziswa ekukhiqizweni kwekhoyili ye-aluminium enemibala ephezulu, ekuqaleni ayesetshenziswa kakhulu emkhakheni wezindiza.
Ukumboza “umphefumulo oyinhloko” wama-coil e-aluminium ambozwe ngombala. Izakhiwo nezinqubo ezahlukene zokumboza zinquma umphumela wombala womkhiqizo, ukumelana nesimo sezulu, kanye nezici zokusebenza. Njengamanje, inqubo yokumboza eyinhloko “ukumboza okubili kanye nokubhaka okubili,” kanye neminye imikhiqizo ephezulu esebenzisa “ukumboza okuthathu kanye nokubhaka okuthathu.” Isakhiwo esithile siqukethe izendlalelo ezintathu kusukela ngaphakathi kuya ngaphandle: Isendlalelo sangaphambi kokwelashwa: “Isithiyo esivikelayo esingaphansi.” Ifilimu ye-oxide ejiyile, cishe ubukhulu obungu-5-10 nm, yakhiwa ebusweni be-substrate ye-aluminium ngokusebenzisa i-chromating noma i-chromium-free passivation. Lokhu kuthuthukisa ukunamathelana phakathi kwe-substrate kanye nokumboza, kuvimbela ukuqhekeka kokumboza, futhi kuthuthukisa ukumelana nokugqwala okuphelele, kubeka isisekelo sokumboza okulandelayo.
Isendlalelo Sesihlomelo: “Isixhumi Esiphakathi kanye Nesendlalelo Esivikelayo.” I-Epoxy noma i-polyester resin isetshenziswa njengesendlalelo, cishe amasentimitha angu-5-10.μubukhulu bayo obuyi-m. Umsebenzi wayo oyinhloko ukuthuthukisa ukunamathela nokuvimba umswakama wangaphandle nomoya-mpilo ukuthi ungathintani ne-substrate, okuthuthukisa ukumelana nokugqwala. Umbala we-primer ungalungiswa ngokuya ngezidingo ze-topcoat ukuqinisekisa umbala wokugcina ofanayo nogqamile.
Isendlalelo Se-Topcoat: “Isendlalelo Esiyinhloko Esinobuhle Nesisebenzayo.” Izinhlobo ezahlukene zama-topcoat zikhethwa ngokwezidingo zokusetshenziswa, cishe ama-15-25μubukhulu bayo buyi-m. Izinhlobo ezivamile ze-topcoat zifaka: Upende we-Fluorocarbon (PVDF): “INkosi Yokuqina Kwangaphandle.” Yenziwe nge-polyvinylidene fluoride resin, inezimpawu ezinhle kakhulu zokumelana ne-UV kanye nezakhiwo zokulwa nokuguga. Ngaphakathi kwezinga lokushisa elingu--40℃kuya ku-150℃, umbala uyamelana nokufiphala futhi uqweqwe alukwazi ukuqhekeka. Futhi lunezici eziqinile zokuzihlanza; amanzi emvula angasusa kalula uthuli olungaphezulu, okwenza lufanelekele ukusetshenziswa kwesikhathi eside njengokwakhiwa kwangaphandle kanye nezindonga zamakhethini angaphandle. Isikhathi sokuphila soqweqwe singafinyelela eminyakeni engaphezu kwengu-20.
Upende we-polyester (PE): “Ukukhetha okungabizi kakhulu.” Izindleko ziphansi ngo-40%-50% kunopende we-fluorocarbon. Nakuba ukusebenza kwawo kokuvimbela ukuguga kungekuhle njengopende we-fluorocarbon, usengaqinisekisa impilo yesevisi yeminyaka eyi-10-15 ezindaweni ezingezona ezezulu kakhulu (njengeCentral kanye neSouthern China). Iphinde inikeze imibala ehlukahlukene ecebile, kufaka phakathi i-matte eyenziwe ngokwezifiso, i-high-gloss, kanye ne-metallic finishes, efanelekile ngaphandle kwefektri, ezimbozweni zemishini, kanye nophahla lwangaphakathi.
Upende we-polyester oguquliwe nge-silicone (SMP): “Inketho yokusebenza elinganiselayo.” Ukuhlanganisa ukusebenza kahle kwepende ye-polyester nokumelana nesimo sezulu kwepende ye-fluorocarbon, inikeza ukumelana okuphezulu kwe-UV uma kuqhathaniswa nopende we-polyester ojwayelekile, inesikhathi sokuphila seminyaka eyi-12-18, futhi ishibhile kunopende we-fluorocarbon. Lokhu kuyenza ifaneleke kumaphrojekthi anezidingo ezithile zokumelana nesimo sezulu kodwa anesabelomali esilinganiselwe, njengezindawo zokungena zezakhiwo zezentengiselwano kanye nama-canopy eziteshi zephethiloli.
Ngokuthuthuka okuqhubekayo kwezobuchwepheshe bezinto zokwakha, amakhoyili e-aluminium ambozwe ngombala azothuthukela ekubeni nobungane obukhulu bemvelo, ukusebenza okwengeziwe, kanye nokwenza kube ngokwakho okukhulu. Ngakolunye uhlangothi, izembozo ezinobungane nemvelo (njengezembozo ezingenayo i-chromium kanye nopende olusekelwe emanzini) zizothatha indawo yezembozo zendabuko kancane kancane, zinciphise umthelela wemvelo. Ngakolunye uhlangothi, amakhoyili e-aluminium ambozwe ngombala anemisebenzi ekhethekile, njengezembozo ezilwa namagciwane, ezivimbela umlilo, kanye nezokuziphilisa, zizoqhubeka nokuvela, zihlangabezane nezidingo zezimo ezikhethekile kakhulu. Ngesikhathi esifanayo, izinsizakalo zokwenza ngokwezifiso ezenziwe ngokwezifiso zizoba zibanzi kakhulu, zivumele imibala kanye nokuthungwa okwenziwe ngokwezifiso ngokusekelwe ezidingweni zomsebenzisi, zandise kakhulu ububanzi bokusetshenziswa kwamakhoyili e-aluminium ambozwe ngombala.
