Nts'etsopele ea Resin e Folisang Leseli Indastering ea Liphutheloana tsa Likhoele tsa LED

Mafapheng a mabone a bohlale le likhoele tsa mabone a khabisitsoeng, phetoho ea theknoloji e etelletsoeng pele ke li-resin tse folisang mabone e ntse e hlalosa bocha sephutheloana sa li-chip tsa LED. Thepa ena e ncha ha e eketse feela katleho ea tlhahiso, empa e boetse e bontša melemo e ikhethang ea ho boloka matla le tšireletso ea tikoloho.

Ha likhoele tsa LED li ntse li ata haholo mabone a khabisitsoeng, mabone a naha le litsamaisong tsa mabone a bohlale, 'maraka o hloka mahlale a mangata a ho paka a sejoale-joale. Lisebelisoa tsa setso tsa thermosetting li pepesitse butle-butle mefokolo e kang lebelo le liehang la ho fola, tšebeliso e ngata ea matla le katleho e tlase.

Jwale, katleho ya moraorao theknolojing ya resin e phekolang lesedi—haholoholo, tshebediso ya UV le metswako e bonahalang ya ho thibela dipitsa, e tlisa ditharollo tse ikgethang indastering yohle.

Katleho ea Tekheniki: Ho tloha Khopolo-taba ho ea Tšebelisong

Li-resin tse folisang khanya li ka tiea ka metsotsoana tlas'a khanya ea ultraviolet kapa e bonahalang. Likarolo tsa tsona tse ka sehloohong li kenyelletsa li-resin tsa acrylate, li-monomer tse arabelang, li-photoinitiator, le lintho tse ling tse tlatsetsang. Ha li pepesetsoa khanya ea maqhubu a itseng a maqhubu, li-photoinitiator li hlahisa li-free radical tse mafolofolo kapa li-cation tse bakang karabelo e hokahanyang pakeng tsa li-monomer le li-resin, e leng se etsang lera le tiileng le sireletsang.

Mokhoa ona oa ho phekola o loketse haholo ho kenngoa ha likhoele tsa LED—kaha li-chip tsa LED ka botsona li ka sebetsa e le mohloli oa leseli bakeng sa ho ipholisa, e leng se nolofalletsang ho iponahatsa.

Ho Sebetsana le Liphephetso tsa Indasteri

Tikoloho e ikhethang ea tšebeliso ea lithapo tsa LED e tlisa liphephetso tse ngata tsa ho paka: lits'ebetso tsa kantle li hloka ho hanela mongobo, liphetoho tsa mocheso le botsofali ba UV; terata e rarahaneng e hloka thepa e nang le phallo e ntle le ho kenella ha metsi; 'me mokhoa oa ho etsa hore likhoele tsa LED li be nyane o hloka thepa e tlatsang likheo tse nyane ka botlalo ntle le ho beha tšebetso ea mahlo kotsing.

Ho paka resin ea epoxy ea setso, ka mathata a kang ho fola butle, tšebeliso e phahameng ea matla, le tšekamelo ea ho ba mosehla, ha ho sa khona ho fihlela litlhoko tsa likhoele tsa LED tsa sejoale-joale bakeng sa tlhahiso e sebetsang hantle le ho tšepahala ha nako e telele.

Bohlokoa bo Sebetsang ba Metswako ea Lipitsa e Folisang Leseli

Metswako e tsoetseng pele ya ho etsa dipitsa e phekolang lesedi hangata e na le acrylate resin (dikarolo tse 40-80), reactive monomer (dikarolo tse 20-40), photoinitiator (dikarolo tse 1-8), le di-additives (dikarolo tse 1-3). Sebopeho se ntlafaditsweng se dumella thepa ho fola ka botlalo ka metsotswana e 2-10 feela tlasa lesedi la LED le nang le matla a mangata, e leng se eketsang bokgoni ba tlhahiso haholo.

Mohlala, epoxy acrylate 61003A e fetotsoeng, e ntshetsweng pele ke Ever Ray. Sehlahiswa sena se fana ka mefuta e fapaneng ya viscosity ya 8,000–18,000 (e leng se etsang hore e lokele ho thehwa ha dome), lebelo la karabelo le potlakileng, ho tiea ho hoholo, le thepa e ikgethang ya ho thibela ho ba mosehla.

Melemo e ikhethang ea Tekheniki

Li-resin tse folisang leseli li fana ka matla a mangata lits'ebetsong tsa ho etsa lipitsa tsa likhoele tsa LED:

Bokgoni ba eneji: Ts'ebetso ea ho tima khanya e ka fokotsa tšebeliso ea motlakase ka 20-80%, e leng se nolofalletsang ho tima ka lebelo le phahameng le ho eketsa bokhoni ba tlhahiso haholo bakeng sa bahlahisi.

Ho ba mosa tikolohong: Metswako e mengata ya sejwalejwale ya dipitsa tse fodisang lesedi ha e na di-solvent le di-isocyanate, tse nang le dikahare tse fokolang haholo tsa organic compound (VOC).

Tshebetso: Lera la encapsulation le phekotsweng le fana ka kgaso e phahameng ya lesedi (>99% ho spectrum e bonahalang), kganyetso ya UV ya nako e telele, le tshireletso e ntle ya mechini le phomolo ya kgatello. Hona jwale, mefuta ya ho pitsa e arotsoe haholo ka tse bonaletsang, tse bonaletsang hanyane, le tse sa bonahaleng.

Litebello tsa 'Maraka o Moholo

Tšebeliso ea li-resin tse folisang leseli tšimong ea LED e ntse e tsoela pele ho atoloha. Ho tloha mabone a bonolo a ponts'o ho ea ho mahlale a kajeno a Mini LED le Micro LED ponts'o, litlhoko tsa thepa ea ho koahela li ntse li eketseha khafetsa.

Lefapheng la likhoele tsa LED, li-resin tse folisang leseli ha li fane ka tšireletso e sebetsang ea chip empa hape li ntlafatsa katleho ea ho ntša leseli, li ntlafatsa tlhahiso ea LED, le ho eketsa bophelo ba tšebeletso. Ka katoloso e tsoelang pele ea 'maraka oa mabone a bohlale le likhoele tsa mabone a khabisitsoeng, menyetla ea theknoloji ea encapsulation e folisang leseli e shebahala e tšepisa haholo.
