Cov iav fiber (Fiberglass) yog cov khoom siv inorganic tsis yog hlau ua tau zoo, ua los ntawm cov iav molten, nrog lub teeb yuag, lub zog siab, tiv taus corrosion, rwb thaiv tsev thiab lwm yam zoo heev. Lub txoj kab uas hla ntawm nws cov monofilament yog ob peb microns txog ntau dua 20 microns, sib npaug rau 1 / 20-1 / 5 ntawm cov plaub hau, thiab txhua pob ntawm cov fiber nyoos yog tsim los ntawm ntau pua lossis txawm tias ntau txhiab monofilaments.
Nws yog raws li chlorite, quartz xuab zeb, limestone, dolomite, boron calcium pob zeb, boron magnesium pob zeb thiab lwm yam minerals ua raw khoom los ntawm high-temperature melting, kos duab, winding, weaving thiab lwm yam txheej txheem rau hauv daim ntaub, yog ib qho kev ua tau zoo heev ntawm inorganic non-metallic cov ntaub ntawv, ntau yam zoo ntawm kev rwb thaiv tsev zoo, kub tsis kam, corrosion tsis kam, siab mechanical zog, tab sis qhov tsis zoo ntawm qhov xwm txheej ntawm brittle, hnav tsis kam yog pluag. Feem ntau nyob rau hauv daim ntawv ntawm monofilament,xov paj, ntaub, xav thiab lwm yam.
01, cov txheej txheem tsim khoom siv iav fiber
1. kev npaj cov khoom siv raw: sib tov cov xuab zeb quartz, limestone thiab lwm yam khoom siv raw hauv qhov sib piv.
2. Kev yaj kub siab: yaj rau hauv cov kua iav ntawm qhov kub siab tshaj 1500 ℃.
3. Kev kos duab thiab tsim: kos duab ntawm kev kub ceev los ntawm platinum-rhodium alloy leakage phaj los tsim cov fiber txuas ntxiv mus.
4. Kev kho qhov chaw: coated nrog wetting agent los txhim kho qhov yooj ntawm cov fiber thiab kev sib txuas nrog resin.
5. Kev ua tiav tom qab: ua rau hauv xov paj, ntaub,siv tawvthiab lwm yam khoom raws li daim ntawv thov.
02, Cov yam ntxwv ntawm cov iav fiber
Lub zog siab: lub zog tensile siab dua li cov hlau ib txwm, tab sis qhov ceev tsuas yog 1/4 ntawm cov hlau.
Kev tiv thaiv corrosion: zoo heev corrosion tsis kam rau acid, alkali, ntsev thiab lwm yam tshuaj lom neeg.
Rwb thaiv tsev: tsis yog-conductive, tsis yog thermal conductivity, yog ib qho khoom siv hluav taws xob zoo heev.
Lub teeb yuag: qhov ceev tsawg, tsim rau cov ntawv thov hnyav.
Kev kub siab ua haujlwm: siv tau ntev hauv -60 ℃ txog 450 ℃.
03. Cov teb tseem ceeb ntawm cov iav fiber
1. Kev tsim kho teb
GFRP bar: lwm txoj hauv kev rau cov hlau rau cov chaw ua haujlwm corrosive xws li kev tsim kho ntug dej hiav txwv thiab cov nroj tsuag tshuaj lom neeg.
Cov khoom siv rwb thaiv tsev phab ntsa sab nraud: lub teeb yuag, tiv taus hluav taws thiab rwb thaiv tsev kub.
Kev txhawb zog ntawm cov pob zeb: txhim kho kev tiv thaiv kab nrib pleb thiab kev ruaj khov.
2. Kev Thauj Mus Los
Lub tsheb sib dua: siv rau hauv cov vaj huam sib luag ntawm lub cev, lub bumpers, chassis thiab lwm yam khoom.
Kev thauj mus los ntawm tsheb ciav hlau: siv rau hauv cov tsheb ciav hlau ceev ceev, sab hauv subway, thiab lwm yam.
Aerospace: siv rau cov dav hlau fairings, radomes, thiab lwm yam.
3. Lub zog tshiab
Cov hniav cua turbine: siv ua cov khoom siv txhawb nqa los txhim kho lub zog ntawm cov hniav thiab kev ua haujlwm qaug zog.
Cov khoom siv photovoltaic: tiv taus corrosion, tsis hnyav, lub neej ntev.
4. Hluav taws xob thiab hluav taws xob
Lub rooj tsavxwm hauv Circuit Court: siv rau FR-4 tooj liab-clad board.
Cov khoom siv rwb thaiv tsev: Siv rau txheej rwb thaiv tsev ntawm lub cev muaj zog, transformer thiab lwm yam khoom siv.
5. Kev tiv thaiv ib puag ncig
Cov ntaub ntawv lim dej: siv rau kev lim roj kub siab, kev kho dej, thiab lwm yam.
Kev kho dej phwj tuaj: siv rau kev ua cov thoob dej thiab cov kav dej uas tiv taus xeb.
04, yav tom ntej kev loj hlob ntawm cov iav fiber
1. Kev ua tau zoo: tsim cov iav fiber nrog lub zog thiab modulus siab dua.
2. Kev tsim khoom ntsuab: txo kev siv zog ntau lawm thiab kev ua qias tuaj rau ib puag ncig.
3. Cov ntawv thov ntse: ua ke nrog cov sensors rau cov khoom sib xyaw ntse.
4. Kev koom ua ke hla ciam teb: sib xyaw nrogcov roj carbon fiber, cov fiber aramid, thiab lwm yam, kom nthuav dav qhov chaw thov.
