Masimong a mekhabiso ea meralo le tlhahiso ea indasteri, likhoele tsa aluminium tse mebala li se li fetoha mokhoa o khethiloeng oa ho khetha thepa ea setso ka lebaka la ts'ebetso ea tsona e ntle le mefuta e fapaneng. Mofuta ona oa khoele, o thehiloeng motsoakong oa aluminium 'me o phekoloa ka' mala le ho penta holim'a metsi, o boloka melemo ea aluminium.—e bobebe ebile e hanela mafome—ha ka nako e ts'oanang e filoe botle bo botle le ts'ebetso e ngata ka ho e sebetsana, e leng se etsang hore e sebelisoe haholo liindastering tse fapaneng.
Thepa ea motheo bakeng sa likhoele tsa aluminium tse mebala-bala haholo-holo ke li-alloy tsa aluminium tsa letoto le le leng, letoto la 3, le letoto la 5. Phapang litšobotsing tsa letoto le fapaneng la thepa ea motheo e ama ka kotloloho maemo a amehang:
Aluminium e hloekileng ea letoto le le leng (hangata e le 1060): Ts'ebetso e bonolo ea tlhahiso, theko e tlase, empa thepa e bonolo haholo, e loketse maemo a akaretsang a nang le litlhoko tse tlase tsa matla (joalo ka ho thibela liphaephe, liboto tsa papatso), e fanang ka katleho e phahameng ka ho fetisisa ea litšenyehelo.
Li-alloy tsa aluminium-manganese tsa letoto la 3 (hangata 3003/3004): 3003 e na le manganese ea 1.0-1.5%, e fanang ka khanyetso e ntle ea mafome. Ho thatafala ha eona le matla a eona a ho thaepa li phahametse li-alloy tsa letoto la 1, e leng se etsang hore e be thepa ea motheo e sebelisoang haholo. 3004 e na le magnesium e eketsehileng ea 0.8-1.3% (e tsejoang hape e le alloy ea aluminium-magnesium-manganese), e leng se fellang ka matla a holimo le ho tšoaneleha bakeng sa ho haha marulelo a nang le litlhoko tse phahameng tsa matla a sebopeho. Theko ea eona e phahame hanyane ho feta 3003.
Li-alloy tsa aluminium-magnesium tsa letoto la 5 (hangata 5052): Li na le magnesium ea 3-5%, li-alloy tsena li na le boima bo tlase, matla a ho thaepa a phahameng, 'me li bobebe. Li theko e boima haholo 'me ka linako tse ling li sebelisoa tlhahisong ea li-coil tsa aluminium tse koahetsoeng ka mebala e phahameng, tse neng li sebelisoa haholo-holo lefapheng la lifofane.
Ho koahela ke "moea oa mantlha" oa likhoele tsa aluminium tse koahetsoeng ka mebala. Meaho le lits'ebetso tse fapaneng tsa ho koahela li khetholla phello ea 'mala oa sehlahisoa, ho hanyetsa boemo ba leholimo, le litšobotsi tsa ts'ebetso. Hona joale, ts'ebetso e kholo ea ho koahela ke "likoahelo tse peli le ho baka tse peli," ka lihlahisoa tse ling tsa maemo a holimo tse sebelisang "likoahelo tse tharo le ho baka tse tharo." Sebopeho se ikhethileng se na le mekhahlelo e meraro ho tloha kahare ho ea holimo: Lera la pele ho kalafo: "Sethibelo se sireletsang ka tlase." Filimi e teteaneng ea oxide, e ka bang botenya ba 5-10 nm, e thehoa holim'a substrate ea aluminium ka ho sebelisa chromating kapa passivation e se nang chromium. Sena se ntlafatsa ho khomarela pakeng tsa substrate le ho koahela, se thibela ho petsoha ha ho koahela, 'me se ntlafatsa ho hanyetsa ho bola ka kakaretso, se beha motheo oa ho koahela ho latelang.
Lera la Primer: “Sehokelo se Mahareng le Lera le Sireletsang.” Epoxy kapa polyester resin e sebelisoa e le lera la primer, hoo e ka bang 5-10μbotenya ba m. Mosebetsi oa eona o ka sehloohong ke ho ntlafatsa ho khomarela le ho thibela mongobo o kantle le oksijene ho kopana le substrate, ho ntlafatsa ho hanyetsa mafome. 'Mala oa primer o ka fetoloa ho latela litlhoko tsa topcoat ho netefatsa 'mala oa ho qetela o ts'oanang le o khanyang.
Lera la Topcoat: “Lera la Core le Botle le Sebetsang.” Mefuta e fapaneng ea li-topcoat e khethoa ho latela litlhoko tsa ts'ebeliso, hoo e ka bang 15-25μBotenya ba m. Mefuta e tloaelehileng ea topcoat e kenyelletsa: Pente ea Fluorocarbon (PVDF): “Morena oa ho Tšoarella ha Kantle.” E entsoe ka resin ea polyvinylidene fluoride, e na le khanyetso e ntle ea UV le thepa ea ho thibela botsofali. Ka har'a mocheso oa -40℃ho isa ho 150℃, 'mala o hanela ho fela 'me lesela ha le peperane habonolo. Hape le na le thepa e matla ea ho itlhoekisa; metsi a pula a ka tlosa lerōle la bokaholimo habonolo, e leng se etsang hore le lokele lits'ebetso tsa ho pepesehela nako e telele joalo ka meaho ea kantle le mabota a kantle a likharetene. Nako ea bophelo ba lesela e ka fihla lilemo tse fetang 20.
Pente ea polyester (PE): “Khetho e theko e tlaase.” Theko e tlase ka 40%-50% ho feta pente ea fluorocarbon. Leha ts'ebetso ea eona ea ho thibela botsofali e se ntle joalo ka pente ea fluorocarbon, e ntse e ka netefatsa bophelo ba ts'ebeletso ea lilemo tse 10-15 libakeng tse seng tsa boemo ba leholimo bo feteletseng (joalo ka Bohareng le Boroa ba Chaena). E boetse e fana ka mefuta e mengata ea mebala, ho kenyeletsoa matte e ikhethileng, e benyang haholo, le liphetho tsa tšepe, tse loketseng kantle ho fektheri, likheo tsa lisebelisoa le siling ea kahare.
Pente ea polyester e fetotsoeng ka silicone (SMP): "Khetho ea ts'ebetso e leka-lekaneng hantle." Ha e kopanya tšebeliso e ntle ea pente ea polyester le ho hanyetsa boemo ba leholimo ba pente ea fluorocarbon, e fana ka khanyetso e phahameng ea UV ha e bapisoa le pente e tloaelehileng ea polyester, e na le nako ea bophelo ea lilemo tse 12-18, 'me e theko e tlase ho feta pente ea fluorocarbon. Sena se etsa hore e lokele merero e nang le litlhoko tse itseng tsa khanyetso ea boemo ba leholimo empa e na le tekanyetso e fokolang, joalo ka mathule a meaho ea khoebo le li-canopies tsa liteishene tsa peterole.
Ka tsoelo-pele e tsoelang pele theknolojing ea thepa, likhoele tsa aluminium tse koahetsoeng ka mebala li tla hola ho ba botsoalle bo boholo ba tikoloho, ts'ebetso e eketsehileng, le ho iketsetsa motho ka mong haholoanyane. Ka lehlakoreng le leng, likhoele tse sireletsang tikoloho (tse kang likhoele tse se nang chromium le lipente tse thehiloeng metsing) li tla nkela likhoele tsa setso sebaka butle-butle, li fokotsa tšusumetso ea tikoloho. Ka lehlakoreng le leng, likhoele tsa aluminium tse koahetsoeng ka mebala tse nang le mesebetsi e ikhethang, joalo ka likhoele tse thibelang likokoana-hloko, tse thibelang mollo le tse iphekolang, li tla tsoela pele ho hlaha, li khotsofatsa litlhoko tsa maemo a ikhethileng haholoanyane. Ka nako e le 'ngoe, lits'ebeletso tsa ho iketsetsa tse ikhethileng li tla ba tse pharaletseng haholoanyane, li lumelle mebala le libopeho tse ikhethileng ho latela litlhoko tsa basebelisi, li ntse li holisa boholo ba ts'ebeliso ea likhoele tsa aluminium tse koahetsoeng ka mebala.
