Dab tsi yog quartz iav fiber?
Quartz iav fiberyog cov khoom siv inorganic fiber nrog silicon dioxide (SiO₂) ntawm ≥99.9% purity ua nws cov khoom tseem ceeb. Nws yog tsim los ntawm kev siv fused silica rod drawing process. Cov khoom siv fiber no ua ke ntau yam zoo heev thiab cov khoom ntawm cov khoom quartz khov kho, ua rau nws yog cov khoom siv tiv taus kub zoo heev. Nws kuj tseem tuaj yeem sib xyaw nrog ceramics, alumina, nitrides, thiab lwm yam khoom siv hauv ntau hom los tsim cov khoom sib xyaw nrog cov khoom tshwj xeeb. Quartz fiber yarn yog ua los ntawm kev sib ntswg thiab plying raw filaments.
Vim li cas cov fiber quartz thiaj muaj zog heev, thiab nws cov khoom zoo dua yog dab tsi?
1. Cov iav fiber quartz muaj kev tiv thaiv kub zoo heev. Nws qhov kub ua haujlwm ntev yog 1050-1200 ℃, thiab nws qhov kub tsis kam tam sim ntawd ncav cuag txog 1700 ℃. Nws tswj tau lub zog siab hauv qab qhov kub siab, tiv taus kev poob siab thermal thiab ablation, thiab tuaj yeem siv rau hauv kev tiv thaiv thermal aerospace, rocket engine nozzles, thiab cov ntaub ntawv rwb thaiv tsev kub.
2. Nws muaj cov khoom dielectric zoo heev thiab kev sib kis nthwv dej zoo. Nws qhov dielectric tas mus li yog qis li 3.7, thiab nws cov coefficient poob dielectric yog <0.001>. Nws muaj qhov poob qis ntawm kev xa cov teeb liab zaus siab thiab kev sib kis nthwv dej siab (txog li 99.3%), uas yog ib qho ntawm cov yam ntxwv tseem ceeb uas ua rau nws haum rau radar domes, antenna radomes, 5G kev sib txuas lus substrates, thiab cov khoom siv tiv thaiv foob pob hluav taws.
3. Cov fiber quartz muaj lub zog kho tshuab siab. Nws lub zog tensile tuaj yeem ncav cuag > 1500MPa, qhov ceev 2.29g / cm³, lub cev sib dua tab sis muaj zog, txo qhov hnyav ntawm cov khoom siv thaum tswj kev ruaj khov. Ntxiv mus, nws tuaj yeem ua ke nrog lwm cov ntaub ntawv los tsim cov khoom siv sib xyaw ua ke zoo, ua rau nws yog cov khoom siv tseem ceeb rau cov khoom siv hauv lub hnub qub.
4. nws qhov kev ruaj khov tshuaj zoo heev yog qhov tseem ceeb. Nrog rau SiO₂ cov ntsiab lus ≥99.9%, nws qhia txog kev tsis muaj zog tshuaj lom neeg thiab kev tiv thaiv corrosion, hloov kho rau cov chaw muaj tshuaj lom neeg hnyav. Qhov no ua rau nws yog qhov kev xaiv zoo tshaj plaws rau cov khoom siv ua semiconductor, cov ntaub ntawv lim dej kub, thiab cov neeg nqa tshuaj lom neeg.
Cov khoom ua los ntawm quartz iav fiber yog siv rau hauv ntau qhov chaw.
1. Cov ntaub plaub Quartz thiab cov ntaub plaub quartz yog cov ntaub uas paub zoo rau cov neeg uas ua qhov kev sim kub siab. Cov no yog cov xov luv luv fluffy ua los ntawm cov ntaub plaub quartz uas tau cua lossis kos, uas tuaj yeem siv ncaj qha lossis ua rau hauv cov ntaub. 1. Cov ntaub plaub Quartz yog tus yam ntxwv los ntawm nws lub teeb yuag, cov qauv porous thiab cov thermal conductivity qis, ua rau nws yog cov khoom siv rwb thaiv tsev kub siab zoo heev. Nws feem ntau siv rau hauv cov txheej rwb thaiv tsev ntawm lub dav hlau lossis hauv cov khoom siv kub siab hauv kev lag luam. Cov khoom rwb thaiv tsev dawb, fluffy, zoo li paj rwb thiab cov khoom rwb thaiv tsev zoo li pam vov ntawm cov platforms hauv cov cub tawg hauv chav kuaj thiab cov cub tawg annealing yog cov ntaub plaub quartz thiab cov ntaub plaub quartz.
2. Txiav txuas ntxiv muscov fibers quartzmus rau qhov ntev uas tau teem tseg yuav ua rau cov fibers quartz txiav ua tej daim me me. Cov no tuaj yeem sib xyaw ua cov resins uas tiv taus kub siab ua cov neeg sawv cev txhawb zog thiab cov neeg sawv cev xa nthwv dej, thiab pwm ua ke los tsim cov khoom siv ablative lossis cov khoom siv rwb thaiv cua sov rau kev tsim cov khoom xws li missile radomes.
3. Cov xov paj quartz fiber yog cov xov txuas ntxiv mus thiab ua haujlwm ua cov khoom siv rau kev xaws tom qab. Raws li ib qho ntawm cov xov paj inorganic uas tiv taus cua sov thiab dielectrically zoo tshaj plaws, nws feem ntau siv ua theem txhawb nqa los xaws ntau yam ntaub lossis ncaj qha rau winding thiab molding composite cov ntaub ntawv. Ntxiv mus, cov thev naus laus zis peb-seem siab heev tso cai rau cov xov paj sib xyaw ua ke hauv qhov chaw. Cov qauv no muaj kev ncaj ncees tag nrho, ua rau nws yog qhov chaw zoo tagnrho rau kev tsim cov khoom sib xyaw ua ke, cov khoom siv thauj khoom siab xws li lub cav foob pob hluav taws nozzles.
4. Quartz fiber ntaubyog xov los ntawm cov xov paj siv cov ntaub weave tiaj tus, twill weave, satin weave, thiab lwm yam txheej txheem. Ua ib yam khoom siv reinforcing, nws yog compounded nrog matrices xws li polyimide thiab epoxy resin los tsim cov khoom siv kub siab rau cov dav hlau, rockets, thiab missiles, nrog rau cov khoom siv cua sov-insulating lossis ablation-resistant rau satellite antennas thiab high-frequency printed circuit boards.
