Ka lebaka la melemo ea ho phekola ka potlako, ho boloka matla le ho sireletsa tikoloho, lihlahisoa tsa phekolo ea UV li sebelisoa haholo libakeng tse ngata, 'me li ne li sebelisoa haholo-holo tšimong ea ho roala lehong.Lilemong tsa morao tjena, ka nts'etsopele ea li-initiators tse ncha, li-diluents tse sebetsang le li-oligomers tse nang le li-photosensitive, ts'ebeliso ea liphahlo tse phekolehang tsa UV e ntse e eketseha butle-butle ho ea masimong a pampiri, polasetiki, tšepe, masela, likarolo tsa likoloi joalo-joalo.Se latelang se tla hlahisa ka bokhuts'oane ts'ebeliso ea Mahlale a 'maloa a Pholiso ea UV mafapheng a fapaneng.
UV e phekola khatiso ea 3D
Khatiso ea 3D e phekolehang ea UV ke e 'ngoe ea mahlale a potlakileng a prototyping a nang le khatiso e phahameng ka ho fetesisa le khoebo.E na le melemo e mengata, joalo ka tšebeliso e tlase ea matla, theko e tlase, ho nepahala ho phahameng, bokaholimo bo boreleli le ho pheta-pheta hantle.E 'nile ea sebelisoa haholo sebakeng sa lifofane, likoloi, tlhahiso ea hlobo, moralo oa mabenyane, bongaka le masimo a mang.
Mohlala, ka ho hatisa prototype ea enjine ea rocket e nang le sebopeho se rarahaneng le ho sekaseka mokhoa oa phallo ea khase, hoa thusa ho rala enjene ea rocket e nang le sebopeho se kopaneng le ts'ebetso e phahameng ea ho chesa, e ka ntlafatsang katleho ea R&D ea likarolo tse rarahaneng le ho sebetsa hantle. khutsufatsa potoloho ea koloi ea R & D;U ka boela ua hatisa hlobo kapa u khutlisetsa hlobo ka ho toba, e le ho etsa hore hlobo ka potlako joalo-joalo.

Lihlahisoa tsa elektroniki tsa ho paka tsa UV
Boqapi ba theknoloji ea ho paka bo khothalletsa phetoho ea thepa ea ho paka ho tloha ho liphutheloana tsa tšepe le liphutheloana tsa ceramic ho ea ho polasetiki ea polasetiki.Epoxy resin ke eona e sebelisoang haholo ho paka polasetiki.Lintho tse ntle haholo tsa mochini, ho hanyetsa mocheso le mongobo ke motheo oa liphutheloana tsa boleng bo holimo.Bothata ba mantlha bo khethollang ts'ebetso ea epoxy resin ha se feela sebopeho sa 'mele o ka sehloohong oa epoxy resin, empa hape le tšusumetso ea moemeli oa pheko.
Ha ho bapisoa le mokhoa oa ho folisa ka mocheso o amohetsoeng ke resin e tloaelehileng ea epoxy, pholiso ea cationic UV ha e na feela botsitso bo betere ba polokelo ea lik'hemik'hale ea photoinitiator, empa hape le lebelo la ho folisa ka potlako la sistimi.Pheko e ka phethoa nakong ea metsotsoana e mashome ka katleho e phahameng haholo.Ha ho na oksijene polymerization inhibition, 'me e ka phekoloa ka botebo.Melemo ena e ntse e totobatsa bohlokoa ba theknoloji ea pholiso ea cationic UV lefapheng la liphutheloana tsa elektroniki.
Ka nts'etsopele e potlakileng ea thekenoloji ea semiconductor, likarolo tsa elektronike li atisa ho kopanngoa haholo le ho fokotseha haholo.Boima bo bobebe, matla a phahameng, ho hanyetsa mocheso o motle le thepa e ntle ea dielectric e tla ba mokhoa oa nts'etsopele ea lisebelisoa tse ncha tse sebetsang hantle tsa epoxy.Theknoloji ea kalafo ea UV e tla bapala karolo ea bohlokoa ho nts'etsopele ea indasteri ea liphutheloana tsa elektroniki.
Enke ea ho hatisa
Lefapheng la ho paka le ho hatisa, theknoloji ea khatiso ea flexographic e sebelisoa haholoanyane, e ikarabellang bakeng sa karolo e ntseng e eketseha.E fetohile theknoloji e ka sehloohong ea ho hatisa le ho paka, 'me ke mokhoa o ke keng oa qojoa oa tsoelo-pele ea nako e tlang.
Ho na le mefuta e mengata ea li-inks tsa khatiso tsa flexo, haholo-holo tse kenyelletsang lihlopha tse latelang: li-inks tse thehiloeng metsing, li-inks tse thehiloeng ho solvent le UV curing (UV).Li-inks tse thehiloeng ho solvent li sebelisoa haholo bakeng sa khatiso ea filimi ea polasetiki e sa monyeng;Enke e thehiloeng metsing e sebelisoa haholo koranteng, boto ea masenke, khateboto le lisebelisoa tse ling tsa khatiso;Enke ea UV e na le mefuta e mengata ea tšebeliso.E na le phello e ntle ea khatiso filiming ea polasetiki, pampiri, foil ea tšepe le lisebelisoa tse ling.
Enke ea UV e na le litšobotsi tsa botsoalle ba tikoloho, bokhoni bo phahameng, boleng bo botle ba khatiso le ho ikamahanya le maemo ho matla.Ke enke e ncha e tsebahalang haholo le e amehileng haholo ea tšireletso ea tikoloho hajoale, 'me e na le tebello e ntle haholo ea nts'etsopele.
Flexographic UV inki e sebelisoa haholo ho paka le ho hatisa.Flexo UV inki e na le melemo e latelang:
(1) Flexographic UV inki ha e na ho qhaqholla ha solvent, ts'ebeliso e bolokehileng le e tšepahalang, sebaka se phahameng sa ho qhibiliha 'me ha se na tšilafalo, ka hona e loketse ho etsa lijo, meriana, seno le liphutheloana tse ling tse nang le litlhoko tse phahameng tsa lisebelisoa tsa ho paka tse sireletsehileng, tse se nang chefo.
(2) Nakong ea khatiso, thepa ea 'mele ea enke e lula e sa fetohe, ha ho na solvent e sa tsitsang, viscosity e lula e sa fetohe,' me poleiti ea khatiso e ke ke ea senyeha, e leng se etsang hore ho be le poleiti ea ho pata, ho pata lipoleiti le liketsahalo tse ling.Ha u hatisa ka enke e phahameng ea viscosity, phello ea khatiso e ntse e le ntle.
(3) Lebelo la ho omisa enke le potlakile mme katleho ea khatiso ea sehlahisoa e phahame.E ka sebelisoa haholo mekhoeng e fapaneng ea khatiso, joalo ka polasetiki, pampiri, filimi le likaroloana tse ling.
Ka nts'etsopele ea sebopeho se secha sa oligomer, diluent e sebetsang le e qalang, boholo ba ts'ebeliso ea nako e tlang ea lihlahisoa tsa UV bo ke keng ba lekanngoa, 'me sebaka sa nts'etsopele ea mmaraka ha se na moeli.
Microspectrum e na le tlhahlobo e ngata le boiphihlelo ba lipatlisiso lefapheng la lihlahisoa tsa pheko ea UV.E hahile pokello ea lintlha tse matla tsa spectrogram mme e na le lisebelisoa tse felletseng tsa tlhahlobo e kholo.Ka mekhoa ea proprietary ea pretreatment le mekhoa ea tlhahlobo ea lisebelisoa, e ka tseba hore na li-monomer tsa maiketsetso le libopeho tsa li-oligomers tse fapaneng, mefuta e fapaneng ea li-diluents tse sebetsang, li-photoinitiators le li-trace additives, joalo-joalo. Ka nako e ts'oanang, microspectrum e latela haufi-ufi ntlafatso ea lihlahisoa tse ncha 'marakeng, mme e etsa lipatlisiso tsa projeke mabapi le lihlahisoa tse ncha tse folisitsoeng tsa UV mafapheng a mangata.E ka bapisa le ho sekaseka bokhabane ba lihlahisoa, ea thusa likhoebo ho rarolla mathata le libaka tse foufetseng tse kopaneng le ts'ebetso ea nts'etsopele ea sehlahisoa, ho khutsufatsa potoloho ea R&D le ho ntlafatsa ts'ebetso ea sehlahisoa.
