Cov qauv tshuaj fluorinated ua rau kev tiv thaiv kev ua tau zoo: kev sib tsoo thiab kev lag luam daim ntawv thov kev coj ua ntawm Parylene F Dev Tshuab
1. Tshuaj lom neeg thiab cov yeeb yaj kiab-ua qauv
Parylene F is a fluorinated poly (p-xylene) derivative with a chemical structure of octafluoroparaxylene dimer, where 8 hydrogen atoms on two benzene rings are replaced by fluorine atoms (molecular formula C88F88H44). The introduction of fluorine atoms significantly improves the material's high temperature resistance (up to 200 ℃ for long-term operation) and UV resistance, while retaining the density, transparency (transparency>95%), thiab rwb thaiv tsev cov khoom ntawm cov khoom siv Parylene.
Nws cov kev npaj cov tshuaj pleev vapor tso nyiaj (CVD) thev naus laus zis, uas tau muab faib ua peb qib:
Sublimation thiab kev tawg: Lub nplhaib nplhaib binary raw cov ntaub ntawv sublime rau hauv cov roj kub (2,5-didethylene benzene) ntawm kwv yees li 680 degree;
Vapor Tso Npe: Cov Monomers Cov Txheej Txheem Polymerize Los ntawm txheej ntawm lub substrate los ua ib zaj yeeb yaj kiab nyias nyias (0.1-100 μ m);
Post Ua Zog: Txhim kho cov nplaum ntawm zaj duab xis txheej los ntawm plasma grafting los yog hais tias kev sib txuas ua ke.
2. Kev ua tau zoo thiab cov ntaub ntawv tseem ceeb txhawb nqa
Cov kev ua tau zoo ntawm cov peregine f yog feem ntau los cuam tshuam hauv cov hauv qab no, uas tau txais kev txhawb nqa los ntawm kev sim cov ntaub ntawv:
Cov kev kub siab dhau: Tom qab ua haujlwm txuas ntxiv ntawm 200℃rau 3000 teev zoo dua li ib txwm muaj dua, uas muaj qhov kub tsis kam 80 degree).
Anti UV Kev Laus: Tom qab 2000 teev ntawm Tshav Ntuj Kev Kawm Tua Tsiaj (Raws li kev hloov pauv JIS tsawg dua 3%, ua kom haum rau sab nraum zoov LED teeb pom kev zoo thiab kev sib txuas lus hauv paus chaw nres tsheb ciav hlau LED
Tshuaj Tiv Thaiv Tshuaj: Nws tsis muaj xeb hauv 5% ntawm cov tshuaj pleev ib puag ncig rau 248 teev, deb tshaj cov khaubncaws tus txheej txheem 2-teev.
Kev Rwb Hluav Taws Xob: Lub zog Dielectric yog ntau dua 7500 v / 25 μ m, uas yog 3.75 zaug ntawm epoxy cob qhia (kwv yees li 2000 v / 25 μ m).
Kev ya raws noo kev ua tsis taus thiab cov pa roj ntsha: Cov pa oxygen permeability yog li 0.00 mm nem), uas tuaj yeem ua kom muaj txiaj ntsig vapor thiab cov pa oxygen.
3. Cov chaw thov lossis cov neeg raug
Ua tsaug rau nws cov kev ua tau zoo, cov Peregrine f tau ua tiav cov ntawv thov tawg hauv cov teb hauv qab no:
1) Automotive Electronics
ECU (hluav taws xob tswj hwm) Kev Tiv Thaiv: Siv rau lub cav hluav taws xob ntawm cov tuam txhab xws li -40 kev hloov pauv, txo qhov tsis ua haujlwm ntawm 82%.
Sensor Kev Tiv Thaiv: Siv cov ntsuas pa oxygen, tiv taus cov roj av vapor thiab acidic corrosion, nrog kev pabcuam lub neej txuas ntxiv 10 xyoo.
2) semiconductor thiab coj teeb pom kev zoo
LED chip packaging: transmittance>95%, suppresses teeb lwj thiab muaj xim muaj xim teeb pom kev zoo, thiab nce nyiaj ntawm 30000 teev (OSRAM Technology dawb).
Cov thawv photovoltaic: Huawei cov thawv sib tshuam sib xyaw nrog Parylene F tau dhau t ü v ntawv pov thawj, nthuav tas lub sijhawm ntawm cov qauv rau 25 xyoos.
3) Aerospace thiab Tub Rog Kev Lag Luam
AirBorne radar thiab phased array kav hlau kav hlau txais xov: Siv rau kev tiv thaiv ferrite, nrog rau huab cua sov thiab hluav taws xob ib puag ncig ntawm huab cua siab.
Spacecraft Electronic Module: tswj rwb thaiv tsev stabulity nyob rau hauv lub tshuab nqus tsev thiab muaj peev xwm ultraviolet ib puag ncig, thiab muaj cov Nasa siv cov tshuab hluav taws xob ntawm Mars sojntsuam.
4) Cov Khoom Siv Kho Mob
Cov khoom siv hluav taws xob: cov pa hluav taws xob sib xyaw siv Parylene F txheej thiab tau dhau ISO 10993 biocompatibility, nrog ion permeability<0.1 ppm (accelerated aging data for 10 years).
Ultrasonic transducer: Txheej tiv thaiv cov precision hluav taws xob Cheebtsam los ntawm cov dej hauv lub cev thiab txhim kho kev ntseeg tau ntawm cov cuab yeej kuaj mob.
