Cov yas fiberglass reinforced yog dab tsi?
Cov yas fiberglass uas muaj zog duayog ib yam khoom sib xyaw ua ke nrog ntau yam, ntau yam khoom sib txawv, thiab ntau yam kev siv. Nws yog ib yam khoom siv tshiab ua los ntawm cov khoom siv hluavtaws thiab fiberglass los ntawm cov txheej txheem sib xyaw.

Cov yam ntxwv ntawm cov yas fiberglass reinforced:
(1) kev tiv thaiv corrosion zoo: FRPyog cov khoom siv tiv taus xeb zoo, rau huab cua; dej thiab feem ntau cov kua qaub thiab alkalis; ntsev thiab ntau yam roj thiab cov kuab tshuaj muaj kev tiv thaiv zoo, tau siv dav hauv txhua yam ntawm kev xeb tshuaj lom neeg. Nws hloov cov hlau carbon; hlau tsis xeb; ntoo; cov hlau tsis yog ferrous thiab lwm yam khoom siv.
(2) Lub teeb yuag thiab lub zog siab:FRP qhov sib piv ntawm qhov ceev yog nruab nrab ntawm 1.5 ~ 2.0, tsuas yog 1/4 ~ 1/5 ntawm cov hlau carbon, tab sis lub zog tensile yog ze rau lossis txawm tias tshaj qhov ntawm cov hlau carbon, thiab lub zog tuaj yeem piv nrog cov hlau alloy qib siab, uas yog siv dav hauv aerospace; cov thawv siab siab nrog rau lwm yam khoom uas xav tau txo qhov hnyav.
(3) cov khoom siv hluav taws xob zoo:FRP yog cov khoom siv rwb thaiv tsev zoo heev rau kev tsim cov insulators, cov zaus siab tseem tuaj yeem tswj tau zoo.
(4) cov khoom siv thermal zoo:FRPKev ua hluav taws xob tsawg, chav sov li ntawm 1.25 ~ 1.67KJ tsuas yog hlau 1/100 ~ 1/1000 yog cov khoom siv rwb thaiv tsev zoo heev. Thaum muaj cua sov sai, nws yog cov khoom siv tiv thaiv thermal zoo tshaj plaws thiab tiv taus corrosion.
(5) kev ua tau zoo heev:raws li cov duab ntawm cov khoom xaiv cov txheej txheem molding thiab cov txheej txheem yooj yim tuaj yeem ua molding.
(6) Tsim tau zoo:cov khoom siv tuaj yeem xaiv tau raws li qhov xav tau kom ua tau raws li qhov xav tau ntawm kev ua tau zoo ntawm cov khoom thiab cov qauv.
(7) qis modulus ntawm elasticity:Qhov modulus ntawm elasticity ntawm FRP yog 2 npaug loj dua li ntoo, tab sis 10 npaug me dua li hlau, yog li nws feem ntau xav tias qhov rigidity tsis txaus hauv cov qauv ntawm cov khoom, thiab nws yooj yim rau deform. Kev daws teeb meem, tuaj yeem ua rau hauv cov qauv plhaub nyias; cov qauv sandwich kuj tuaj yeem ua los ntawm cov fiber ntau modulus lossis cov qauv reinforcing rib.
(8) Kev tiv taus kub tsis zoo mus sij hawm ntev:dav davFRPtsis tuaj yeem siv ntev ntawm qhov kub siab, cov khoom siv dav dav polyester resin FRP ntawm 50 degrees saum toj no lub zog yuav raug txo qis heev.
(9) Kev laus zuj zus:nyob rau hauv lub teeb ultraviolet; cua, xuab zeb, nag thiab daus; tshuaj lom neeg xov xwm; kev ntxhov siab ntawm lub tshuab thiab lwm yam teebmeem yooj yim ua rau kev ua haujlwm poob qis.
(10) Lub zog txiav ntawm cov txheej txheem qis:Lub zog shear ntawm cov txheej txheem yog los ntawm cov resin, yog li nws qis. Nws muaj peev xwm txhim kho lub zog sib txuas ntawm cov txheej txheem los ntawm kev xaiv cov txheej txheem, siv cov neeg sawv cev sib txuas thiab lwm txoj hauv kev, thiab zam kev shear ntawm cov txheej txheem ntau li ntau tau thaum tsim cov khoom.
