Ntau yam khoom siv fiberglass
Fiberglass yog ib qho zoo heev inorganic non-metallic khoom.iav fiber ntauyog ib hom ntuj inorganic non-metallic ore xws li leucolite, pyrophyllite, kaolin, quartz xuab zeb, limestone, thiab lwm yam. High-grade inorganic fibers muaj ib txoj kab uas hla ntawm ob peb microns mus rau ntau tshaj 20 microns, uas yog sib npaug rau 1. /20-1/5 ntawm cov plaub hau.
Muaj ntau hom iav fiber ntau, uas yog tsim rau cov xwm txheej sib txawv.Cov iav fiber ntau tuaj yeem muab faib ua ntau hom raws li qhov muaj pes tsawg leeg, xws li tsis-alkali, nruab nrab-alkali, siab-alkali, siab-lub zog, boron-dawb thiab tsis-alkali, thiab lwm yam. nyob rau hauv txawv teb raws li nws cov kev ua tau zoo yam ntxwv.Piv txwv li, iav fibers nrog alkali hlau oxide cov ntsiab lus tsawg dua 0.8% yogalkali-dawb iav fibers, uas muaj cov khoom siv hluav taws xob zoo thiab cov khoom siv kho tshuab, tab sis cov kua qaub tsis zoo, yog li lawv tau siv dav hauv cov xwm txheej uas yuav tsum tau muaj hluav taws xob rwb thaiv tsev lossis hauv FRP;Cov ntsiab lus ntawm 11.9% -16.4% belongs rau nruab nrab-alkali iav fiber, uas muaj zog acid kuj tab sis tsis zoo hluav taws xob kev ua tau zoo, thiab nws lub zog txhua yam yog qis dua li cov iav fiber ntau uas tsis yog alkali.Nws yog siv nyob rau txawv teb chaws rau cov khoom siv ntxiv asphalt vov tsev nrog cov khoom siv zog qis dua;High-strength iav fiber ntau muaj qee qhov nyiaj ntawm zirconia, uas muaj cov yam ntxwv ntawm lub zog tensile siab, cov zis qis thiab cov nqi siab, yog li nws yog siv hauv cov khoom siv tub rog;Tsis tas li ntawd, high-alkali fiber ntau muaj kev ua haujlwm tsis zoo thiab tau pib tshem tawm.
Fiberglass Composite
Cov iav fiber ntau kuj tuaj yeem ua ke nrog lwm cov ntaub ntawv los ua iav fiber ntau cov ntaub ntawv, uas FRP yog cov khoom tseem ceeb.Cov iav fiber ntau tuaj yeem ua ke nrog cov resin los ua iav fiber reinforced yas (FRP), los yog ntxiv asphalt los ua iav fiber reinforced asphalt.Vim muaj ntau yam khoom siv uas tuaj yeem sib xyaw ua ke, tam sim no tsis muaj kev qhia meej meej ntawm cov khoom siv iav fiber ntau.Raws li cov ntaub ntawv ntawm Qianzhan Kev Lag Luam Kev Tshawb Fawb Lub Tsev Haujlwm, FRP suav txog li 75% ntawm kev ua lag luam rau iav fiber ntau cov ntaub ntawv thiab cov khoom lag luam, tuav txoj haujlwm tseem ceeb.Yog li ntawd, peb coj FRP ua piv txwv los txheeb xyuas qhov ua tau zoo ntawm cov iav fiber ntau.
FRP yog lwm cov khoom siv nrog kev ua haujlwm zoo.FRP yog cov khoom sib xyaw nrog cov khoom siv hluavtaws ua cov matrix thiab iav fiber ntau thiabcov khoom siv fiberglass(mats, ntaub, siv, thiab lwm yam) raws li cov khoom siv reinforcing.FRP tau txais nws lub npe los ntawm nws cov iav zoo li lub ntsej muag thiab lub zog zoo li lub zog tensile.Piv nrog rau cov hlau ntau tshaj plaws hauv kev tsim kho, qhov ntom ntawm cov hlau yog 7.85 × 103kg / m3, thiab qhov ntom ntawm FRP yog 1.9 × 103kg / m3, uas yog sib zog dua hlau, thiab nws lub zog tshwj xeeb thiab kev tiv thaiv corrosion nyob deb tshaj hlau;piv nrog aluminium alloy, thermal conductivity ntawm aluminium alloy yog 203.5W / m. ℃, thiab thermal conductivity ntawm FRP yog 0.3W / m. ℃.Lub thermal rwb thaiv tsev kev ua tau zoo ntawm FRP yog zoo dua, thiab kev pab cuam lub neej ntawm FRP yog 50 xyoo, uas yog ob zaug ntawm txhuas alloy.Vim nws txoj kev ua tau zoo heev, FRP, ua ib qho kev hloov rau cov khoom siv ib txwm siv, yog siv dav hauv kev tsim kho, kev tsheb ciav hlau, aerospace, yacht berthing thiab lwm yam lag luam.
iav fiber ntau kev lag luam saw
Cov khoom siv raw ntawm cov iav fiber ntau yog qhov yooj yim kom tau, thiab cov ntawv thov hauv qab yog qhov dav.Cov khoom siv raw rau iav fiber ntau yog cov khoom siv raw khoom thiab cov khoom siv tshuaj lom neeg, suav nrog pyrophyllite, kaolin, quartz xuab zeb, limestone, thiab lwm yam, uas yog cov ntxhia pob zeb nrog loj reserves hauv Suav teb, thiab nws yog ib qho nyuaj kom tau txais;lub zog siv yog tsuas yog hluav taws xob thiab cov nkev roj;Cov kev siv downstream Nws yog qhov dav, feem ntau suav nrog cov khoom siv hauv tsev, kev thauj mus los, cov khoom siv hluav taws xob, cov khoom siv hauv tsev, lub zog thiab kev tiv thaiv ib puag ncig thiab lwm yam.
