GFRP, cov yas ua los ntawm iav fiber, yog cov khoom siv tsis yog hlau nrog qhov chaw du thiab lub cheeb sab nraud sib npaug tau los ntawm kev txheej cov nplaim ntawm ntau txoj hlua iav fiber nrog cov tshuaj kho lub teeb. GFRP feem ntau siv ua lub hauv paus muaj zog rau cov xov hluav taws xob sab nraum zoov, thiab tam sim no ntau thiab ntau dua cov xov hlau tawv siv.
Ntxiv rau kev siv GFRP ua tus tswv cuab muaj zog, cov xov hlau tawv kuj tseem siv tau KFRP ua tus tswv cuab muaj zog. Qhov txawv ntawm ob qho no yog dab tsi?
Txog GFRP
1. Tsawg qhov ceev, muaj zog siab
Qhov sib piv ntawm GFRP yog nruab nrab ntawm 1.5 thiab 2.0, uas tsuas yog 1/4 txog 1/5 ntawm cov hlau carbon, tab sis lub zog tensile ntawm GFRP yog ze rau lossis txawm tias ntau dua li cov hlau carbon, thiab lub zog ntawm GFRP tuaj yeem piv rau cov hlau alloy qib siab.
2. Kev tiv thaiv xeb zoo
GFRP yog cov khoom siv tiv taus corrosion zoo, thiab muaj kev tiv taus zoo rau huab cua, dej thiab cov concentration ntawm cov kua qaub, alkalis, ntsev, thiab ntau yam roj thiab cov kuab tshuaj.
3. Kev ua haujlwm hluav taws xob zoo
GFRP yog cov khoom siv rwb thaiv tsev zoo dua thiab tseem tuaj yeem tswj tau cov khoom dielectric zoo ntawm cov zaus siab.
4. Kev ua haujlwm zoo thermal
GFRP muaj cov thermal conductivity tsawg, tsuas yog 1/100 ~ 1/1000 ntawm cov hlau ntawm chav tsev kub.
5. Kev ua haujlwm zoo dua
Cov txheej txheem molding tuaj yeem xaiv tau yooj yim raws li cov duab, qhov yuav tsum tau ua, kev siv thiab qhov ntau ntawm cov khoom.
Cov txheej txheem yooj yim thiab cov txiaj ntsig kev lag luam zoo heev, tshwj xeeb tshaj yog rau cov khoom uas muaj cov duab nyuaj uas tsis yooj yim rau kev tsim, nws cov khoom siv tes ua haujlwm zoo dua.
Txog KFRP
KFRP yog lub npe luv ntawm cov yas aramid fiber reinforced. Nws yog cov khoom siv tsis yog hlau nrog qhov chaw du thiab lub cheeb sab nraud sib npaug, uas tau los ntawm kev txheej cov xov paj aramid nrog cov tshuaj kho lub teeb. Nws yog siv dav hauv kev nkag mus rau hauv network.
1. Tsawg qhov ceev, muaj zog siab
KFRP muaj qhov ceev tsawg thiab muaj zog siab, thiab nws lub zog thiab cov modulus tshwj xeeb ntau dua li cov hlau hlau thiab GFRP.
2. Kev nthuav dav tsawg
Tus coefficient ntawm kev nthuav dav ntawm KFRP yog me dua li ntawm cov hlau hlau thiab GFRP hauv qhov kub thiab txias dav.
3. Kev cuam tshuam tsis kam, tawg tsis kam
KFRP tsis yooj yim rau kev cuam tshuam thiab tsis yooj yim tawg, thiab tseem tuaj yeem tswj tau lub zog tensile ntawm li 1300MPa txawm tias muaj kev tawg.
4. Kev ywj pheej zoo
KFRP yog mos thiab yooj yim khoov, ua rau cov xov hluav taws xob sab hauv tsev muaj cov qauv me me, zoo nkauj thiab kev ua tau zoo heev, thiab tshwj xeeb tshaj yog tsim rau kev txuas hluav taws xob hauv ib puag ncig sab hauv tsev nyuaj.
Los ntawm kev tshuaj xyuas tus nqi, tus nqi ntawm GFRP muaj txiaj ntsig zoo dua.
Tus neeg yuav khoom tuaj yeem txiav txim siab seb yuav siv cov khoom siv twg raws li qhov xav tau tshwj xeeb thiab kev txiav txim siab txog tus nqi.
