Cov qauv tshawb fawb daws teeb meem qis dua pib
Cov cim cim kev ntsib qhov kev sib tw me me: ua tiav qhov kev ua kom zoo thaum pib ua kom zoo thaum ua haujlwm hnav, UV kis, thiab huab cua. Advultient incientific cov qauv tsim nyog hais txog qhov no los ntawm kev txhim kho cov khoom ua haujlwm thiab kev ua lag luam.
1. High-tsev qiv nyiaj & iav bead anchoring
Cov txheej txheem ruaj khov (E.G., PMMA hauv ob-Txheej Txheem Ua kom nruj heev uas mechanically "thauj tog rau nkoj" iav hlaws "iav iav, tiv thaiv 脱落. Resin cov ntsiab lus ≥25% ua kom meej meej adhesion lub zog, txo cov hlaws tsis ploj mus <20% tom qab 2 xyoos ntawm kev tsheb.
2. Refunt index (RI) muab qhab nia
Sib txuas RI 1.5 hlaws dai (thawj zaug kev cuam tshuam: 150-200 MCD) nrog RI 1.7+ reads (ntev kev xav: 350-600 MCD) tsim kev kub ntxhov zuj zus. Ntau dua Ri hlaws dai tswj kev ua tau zoo raws li cov ntoo saum npoo.
3. Tio ectimization & UV stabilization
5-10% rutile tio₂ txhim kho whiteness (l * tus nqi ≥90) thiab UV tsis kam. Coupled nrog hindered amine lub teeb cigilizers (hales), nws txo cov yaig (≤1,5 tom qab 5 xyoos).
4. Embedded Qhov tob Tswj
Cov hlaws dai ntawm 55-67% qhov tob tob kom ua raws li cov txheej txheem ntawm lub focal nrog cov txheej txheej sib txawv txheej txheej. Caw kaw cov tshuaj tua kom ua kom muaj kev faib tawm cov khoom sib txuam thiab kev ua kom zoo dua.
5. Hybrid Bead Systems
Rispoof hlaws dai nrog RI 1.75-2.40 MCD reflectivity nyob rau hauv hnyav los nag, thaum lub sij hawm fluorescent addection) muab 8-10 teev ntawm tom qab lub teeb pom kev zoo.
Qhov tshwm sim: Cov Qauv Ua Niaj Hnub No Raug Rho Tawm ≥350 MCD nrog <10% Luv ntawm QU-2000 teev tom qab 2-8 xyoo- 2.3 × ntev dua li cov tshuaj sib xyaw. Los ntawm synings chemistry, optics, thiab daim ntawv thov raws li cov kev daws teeb meem ua rau pom zoo nyob hauv lawv txoj kev ua haujlwm.
