Kev Txhim Kho Cov Khoom Siv Kho Lub Teeb Hauv Kev Lag Luam Ntim Khoom LED String

Hauv kev lag luam ntawm lub teeb pom kev zoo thiab cov hlua teeb pom kev zoo nkauj, kev hloov pauv thev naus laus zis coj los ntawm cov resins kho lub teeb tau txhais dua lub pob khoom LED chips. Cov khoom siv tshiab no tsis yog tsuas yog ua kom muaj txiaj ntsig zoo dua xwb, tab sis kuj qhia txog cov txiaj ntsig zoo hauv kev txuag hluav taws xob thiab kev tiv thaiv ib puag ncig.

Thaum cov hlua LED dhau los ua ntau dua hauv cov teeb pom kev zoo nkauj, teeb pom kev zoo hauv toj roob hauv pes, thiab cov tshuab teeb pom kev zoo ntse, kev ua lag luam xav tau ntau cov thev naus laus zis ntim khoom zoo tshaj plaws. Cov ntaub ntawv thermosetting ib txwm muaj maj mam nthuav tawm cov kev txwv xws li kev kho qeeb qeeb, kev siv hluav taws xob ntau, thiab kev ua haujlwm qis.

Tam sim no, qhov kev ua tiav tshiab tshaj plaws hauv kev siv tshuab ua kom cov khoom siv kho kom zoo nkauj - tshwj xeeb tshaj yog, kev siv UV thiab cov khoom siv kho kom zoo nkauj uas pom tau, tab tom coj cov kev daws teeb meem tshiab rau tag nrho kev lag luam.

Kev Txhim Kho Txuj Ci: Los Ntawm Kev Xav Mus Rau Kev Siv

Cov tshuaj pleev xim uas siv lub teeb ci tuaj yeem khov tau hauv ob peb feeb xwb thaum nyob hauv lub teeb ultraviolet lossis lub teeb pom kev. Lawv cov khoom tseem ceeb suav nrog acrylate resins, reactive monomers, photoinitiators, thiab ntau yam khoom ntxiv. Thaum raug lub teeb ntawm cov wavelengths tshwj xeeb, cov photoinitiators tsim cov free radicals lossis cations uas ua rau muaj kev sib txuas ntawm cov monomers thiab cov resins, tsim ib txheej tiv thaiv khov kho.

Lub tshuab kho no yog qhov tshwj xeeb tshaj yog rau LED txoj hlua encapsulation - txij li thaum cov LED chips lawv tus kheej tuaj yeem ua lub teeb rau kev kho, ua rau nws tus kheej-encapsulation.

Kev daws teeb meem kev lag luam

Cov chaw siv tshwj xeeb ntawm cov hlua LED coj ntau yam teeb meem ntim khoom: kev siv sab nraum zoov xav tau kev tiv thaiv dej noo, qhov kub thiab txias hloov pauv, thiab UV laus; cov xov hlau nyuaj xav tau cov ntaub ntawv uas muaj kev ywj pheej zoo thiab permeability; thiab qhov sib txawv ntawm miniaturization xav tau cov ntaub ntawv uas sau tag nrho cov qhov me me yam tsis muaj kev cuam tshuam rau kev ua haujlwm ntawm lub teeb.

Cov khoom ntim epoxy resin ib txwm muaj, nrog rau cov teeb meem xws li kev kho qeeb, kev siv hluav taws xob ntau, thiab kev nyiam daj, tsis tuaj yeem ua tau raws li qhov xav tau ntawm cov hlua LED niaj hnub rau kev tsim khoom zoo thiab kev ntseeg siab mus sij hawm ntev.

Tus Nqi Siv Tau ntawm Cov Tshuaj Sib Xyaws Uas Kho Tau Lub Teeb

Cov tshuaj cog qoob loo uas siv lub teeb ci ntsa iab feem ntau muaj cov acrylate resin (40-80 feem), reactive monomer (20-40 feem), photoinitiator (1-8 feem), thiab cov tshuaj ntxiv (1-3 feem). Cov mis tshuaj zoo tshaj plaws no ua rau cov khoom siv no kho tau tag nrho hauv 2-10 vib nas this xwb hauv qab lub teeb LED muaj zog heev, ua rau kev tsim khoom zoo dua qub.

Piv txwv li, hloov kho epoxy acrylate 61003A, tsim los ntawm Ever Ray. Cov khoom no muaj qhov viscosity ntawm 8,000–18,000 (ua rau nws tsim nyog rau kev tsim lub dome), kev teb ceev ceev, kev tawv zoo heev, thiab cov yam ntxwv tiv thaiv kev daj zoo heev.

Cov Kev Zoo Tshaj Plaws ntawm Kev Siv Tshuab

Cov tshuaj kho lub teeb muaj ntau lub zog hauv cov ntawv thov LED hlua potting:

Kev siv hluav taws xob zoo: Cov txheej txheem kho lub teeb tuaj yeem txo qhov kev siv hluav taws xob los ntawm 20–80%, ua rau kev kho sai sai thiab ua rau muaj peev xwm tsim khoom ntau ntxiv rau cov chaw tsim khoom.

Kev phooj ywg ib puag ncig: Feem ntau cov tshuaj cog paj uas siv lub teeb kho niaj hnub no tsis muaj cov kuab tshuaj thiab isocyanates, nrog rau cov organic compound volatile (VOC) tsawg heev.

Kev Ua Tau Zoo: Cov txheej encapsulation kho tau muab kev xa lub teeb siab (> 99% hauv qhov pom kev), tiv taus UV ntev, thiab kev tiv thaiv zoo heev thiab kev txo kev ntxhov siab. Tam sim no, cov hom lauj kaub feem ntau yog muab faib ua pob tshab, ib nrab pob tshab, thiab tsis pom kev.

Kev Lag Luam Dav Dav

Kev siv cov tshuaj kho lub teeb hauv thaj chaw LED txuas ntxiv nthuav dav. Txij li cov teeb qhia yooj yim mus rau Mini LED thiab Micro LED cov thev naus laus zis niaj hnub no, qhov yuav tsum tau ua rau cov ntaub ntawv encapsulation pheej nce ntxiv.

Hauv kev lag luam LED hlua, cov tshuaj kho lub teeb tsis muab kev tiv thaiv zoo rau cov chips tab sis kuj txhim kho kev ua haujlwm ntawm lub teeb, txhim kho cov zis LED, thiab ntev lub neej kev pabcuam. Nrog rau kev nthuav dav ntawm kev lag luam teeb pom kev zoo ntse thiab cov hlua teeb kho kom zoo nkauj, kev cia siab rau cov thev naus laus zis kho lub teeb zoo li muaj kev cia siab heev.

Cov ntaub ntawv kev lag luam qhia tau hais tias kev lag luam ntim khoom siv LED loj hlob ntawm qhov nruab nrab txhua xyoo li ntawm 10%, nrog rau kev siv tshuab kho lub teeb yog ib qho ntawm cov ntu loj hlob sai tshaj plaws. Cov thev naus laus zis no tsis yog tsuas yog ua kom muaj txiaj ntsig zoo xwb tab sis kuj tseem ua rau cov khoom zoo thiab kev ntseeg siab dua, muab kev txhawb nqa zoo rau kev txhim kho kev lag luam teeb pom kev zoo LED.
