Selelekela:
Ho roala ka rolara e se e le mokhoa o ratoang oa ho sebelisa litlolo holim'a likhoele tsa aluminium ka lebaka la ts'ebetso le ts'ebetso ea eona.Ka tlhokahalo e ntseng e eketseha ea lihlahisoa tsa aluminium tsa boleng bo phahameng le tse tšoarellang nako e telele, ho roala rolara ho fetohile mokhoa oa bohlokoa indastering ea aluminium.Leha ho le joalo, e le hore u finyelle liphello tse lakatsehang, ke habohlokoa ho utloisisa litlhoko tse khethehileng tsa tshebetso bakeng sa ho roala rolara.Ho blog ena, re tla hlahlobisisa litlhoko tsa bohlokoa tsa ts'ebetso tseo liaparo tsa rolara li tlamehang ho li phethahatsa, re shebane le viscosity le thepa ea boemo bo holimo, pheko e potlakileng, likarolo tsa mokhabiso le ho hanyetsa boemo ba leholimo.
1. Viscosity e nepahetseng le thepa e ntle ea boemo:
Mokhoa oa ho roala li-roller o kenyelletsa ho fepa ka lebanta ka potlako, ho roala li-roller, ho baka mocheso o phahameng, le ho pholisa ka potlako.E le ho etsa bonnete ba hore thepa e lekaneng ea ho lekana, ho bohlokoa hore rolara ea ho roala e sebelise pente e lekaneng holim'a thepa ea aluminium.Ka hona, liaparo tsa ho roala li tlameha ho ba le viscosity e nepahetseng le thepa e ntle ea boemo.Viscosity ea ho roala e lokela ho hlophisoa ka hloko ho lumella tšebeliso e bonolo ha e ntse e boloka bokhoni ba eona ba ho lekana ka holim'a aluminium.Ho fihlella tekano e nepahetseng ea viscosity ho bohlokoa ho thibela litaba tse joalo ka botenya bo sa lekanang, li-streaks le litlamorao tsa lekhapetla la lamunu.
2. Pheko e potlakileng:
Ka lebaka la tlhaho e potlakileng ea mela ea tlhahiso ea li-roller, ho phekola ka potlako ke tlhokahalo ea bohlokoa bakeng sa ho roala li-roller.Ha ho na tšehetso le bolelele bo fokolang ba ontong ea ho baka, nako e fumanehang ea ho penta e fokotsehile haholo.Lipente tse sebelisitsoeng ho roala li tlameha ho etsoa hore li fole ka nako e khuts'oane, haholo-holo ka tlase ho metsotsoana e 60.Ho feta moo, mokhoa oa ho folisa o lokela ho boloka pente e le ka tlase ho mocheso oa 260°C ho thibela thepa ho tloha deformation kapa karabelo e meng e sa thabiseng.Khetho e nepahetseng ea solvent ea hlokahala ho fumana pheko e potlakileng ntle le ho sekisetsa ho ts'epahalla ha lesela, ho qoba litaba tse tloaelehileng joalo ka ho phatloha, li-pinholes le boemo bo bobe.
3. Likarolo tsa mekhabiso:
Ntle le thepa e sebetsang, liaparo tsa ho roala li-roller li tlameha ho finyella litlhoko tsa mokhabiso.Hangata pente ea polyester e lekane ho finyella ponahalo e lakatsehang ka kopo e le 'ngoe.Leha ho le joalo, ha u sebelisa seaparo sa fluorocarbon, primer le topcoat lia hlokahala bakeng sa liphello tse ntle tsa mokhabiso.Primer e lokela ho ba le khanyetso e ntle ea kutu le ho khomarela substrate le topcoat, athe topcoat e lokela ho bonts'a matla a ho ipata le thepa ea mokhabiso.Seaparo se le seng sa primer se lateloang ke seaparo se le seng sa topcoat se ka fella ka ponahalo e ntle e finyellang litlhoko tse ntle le tse sebetsang.
4. Ho hanyetsa boemo ba leholimo:
Liaparo tsa rolara li tlameha ho bonts'a khanyetso e ikhethang ea boemo ba leholimo, haholo ha li sebelisoa lihlahisoa tsa aluminium tsa kantle.Liaparo tsa PVDF tsa fluorocarbon hangata li sebelisoa ho fana ka ts'ebetso e felletseng khahlano le lintlha tse kang ho tšoarella, pula ea asiti, tšilafalo ea moea, kutu, matheba a emeng, le hlobo.Ho ipapisitsoe le litlhoko tse ikhethileng tsa sebaka, ho ka sebelisoa lijase tse peli, tse tharo kapa tse nne tsa PVDF.Sena se tiisa tšireletso ea nako e telele le ho tiea ho hoholo, ho lumella khoele ea aluminium e koahetsoeng hore e mamelle esita le maemo a thata ka ho fetisisa a tikoloho.
Qetello:
Qetellong, ho finyella ts'ebetso e ikhethang ea ho roala li-roller bakeng sa li-coil tsa aluminium ho hloka ho nahanisisoa ka hloko ka viscosity ea ho roala le thepa ea ho lekanya, bokhoni ba ho phekola ka potlako, likarolo tsa ho khabisa le ho hanyetsa boemo ba leholimo.Ka ho utloisisa le ho khomarela litlhoko tsena tsa ts'ebetso, bahlahisi ba ka hlahisa lihlahisoa tsa aluminium tse koahetsoeng ka boleng bo phahameng tse finyellang litekanyetso tse boima tsa liindasteri tse sa tšoaneng.Ha tlhokahalo ea li-coil tsa aluminium tse ka tšeptjoang le tse bonahalang li ntse li hōla, ke habohlokoa ho beha pele khetho le tšebeliso ea liphahlo tsa rolara tse ka phethahatsang litlhoko tsena tsa bohlokoa tsa ts'ebetso.
