Cheebtsam ntawm lub koob yees duab
Lub koob yees duab yog tsim los ntawm cov iav kho qhov muag.Cov iav kho qhov muag yog ua los ntawm high-purity silicon, boron, sodium, potassium, zinc, lead, magnesium, calcium, barium thiab lwm yam oxides sib xyaw ua ke raws li ib qho kev qhia tshwj xeeb, melted hauv platinum crucible ntawm qhov kub thiab txias, thiab ultrasonic sib tov sib xyaw thiab tshem tawm npuas;tom qab ntawd maj mam txias rau lub sijhawm ntev kom tsis txhob muaj kev ntxhov siab hauv lub khob thaiv.Cov iav txias yuav tsum tau ntsuas los ntawm cov cuab yeej kho qhov muag los xyuas seb qhov purity, transparency, uniformity, refractive index thiab dispersion npaum li cas raws li cov specifications.Qhov tsim nyog iav thaiv yog rhuab thiab forged los ua ib qho optical lens dawb paug.
Lub teeb-kho cov nplaum uas siv rau hauv kev sib dhos ntawm cov koob yees duab modules thiab cov lo ntsiab muag kho qhov muag yuav tsum tau tiv thaiv ib puag ncig hnyav ntawm cov av noo, kub thiab muaj zog cuam tshuam uas feem ntau pom hauv cov khoom siv hluav taws xob, thiab cov khoom feem ntau yuav tsum tau ua raws li cov hauv qab no:
1. Tsawg shrinkage: Kev taw qhia txog cov txheej txheem ua kom pom tseeb thaum lub sijhawm sib dhos ntawm lub koob yees duab module lens puag thiab lub rooj tsav xwm Circuit Court tuaj yeem daws qhov teeb meem ntawm cov khoom lag luam tawm los thiab ua kom lub lens ua kom pom tseeb zoo tshaj plaws ntawm tag nrho cov duab dav hlau.Ua ntej siv lub teeb-kho qhov chaw, ua ntej kho lub lens peb-dimensionally, ntsuas qhov zoo tshaj plaws txoj hauj lwm, thiab tom qab ntawd ua kom tiav qhov kawg kho los ntawm lub teeb thiab cua sov.Yog tias qhov shrinkage tus nqi ntawm cov nplaum siv tsawg dua 1%, nws tsis yooj yim ua rau lub lens txoj hauj lwm hloov.
2. Tsawg coefficient ntawm thermal expansion: Lub coefficient ntawm thermal expansion yog abbreviated li CTE, uas yog hais txog qhov tsis tu ncua coefficient tias cov yam ntxwv geometric ntawm cov khoom hloov pauv nrog kev hloov ntawm qhov kub thiab txias nyob rau hauv cov nyhuv ntawm thermal expansion thiab contraction.Lub koob yees duab siv rau kev ua haujlwm sab nraum zoov yuav ntsib qhov xwm txheej ntawm qhov nce / poob ntawm qhov kub thiab txias.Yog tias qhov thermal expansion coefficient ntawm cov nplaum yog siab dhau, lub lens yuav poob siab thiab cuam tshuam rau kev ua haujlwm.
3. Nws tuaj yeem kho tau ntawm qhov kub thiab txias: cov khoom siv raw ntawm lub koob yees duab module tsis tuaj yeem ci ntawm qhov kub thiab txias rau lub sijhawm ntev, txwv tsis pub qee cov khoom yuav raug puas los yog kev ua haujlwm yuav raug cuam tshuam.Yog tias cov nplaum tuaj yeem kho tau sai ntawm qhov kub qis ntawm 80 ° C, nws tuaj yeem zam cov khoom poob thiab txhim kho cov khoom tawm los.
4. LED curing: Piv nrog cov khoom siv kho mob, cov khoom siv hluav taws xob siab mercury thiab hlau halide teeb muaj lub neej kev pab tsuas yog 800 mus rau 3,000 teev, thaum lub teeb raj ntawm UV-LED ultraviolet curing khoom muaj lub neej kev pab ntawm 20,000- 30,000 teev, thiab tsis muaj ozone raug tsim thaum lub sijhawm ua haujlwm., uas tuaj yeem txo kev siv hluav taws xob los ntawm 70% mus rau 80%.Feem ntau lub teeb-kho cov nplaum siv LED kho cov cuab yeej kom ua tiav kev kho thawj zaug hauv 3 mus rau 5 vib nas this.
