Lub Allure ntawm Basalt Fiber
Lub tswv yim ntawm kev tsim cov fibers los ntawm basalt tsis yog tshiab. Thawj patent rau basalt fiber ntau raug tsim tawm hauv xyoo 1923, thiab thaum xyoo 1950 thiab 1960s, kev tshawb fawb dav dav tsom rau nws cov ntawv siv tub rog. Txawm coj iav Fiber Cov neeg tsim khoom tshawb nrhiav basalt lub peev xwm thaum lub sijhawm, txawm hais tias lawv tau hloov lawv qhov R & D tsom rau xyoo 1970s mus rau kev ua tau zoo dua iav fibers zoo li S-2. Tau ntau xyoo lawm, kev txaus siab rau basalt fiber ntau tau hloov pauv, tab sis nyob rau xyoo tas los no, nws tau nce tsis tu ncua.
Muab hais tias basalt originates los ntawm magnesium- thiab hlau-nplua nuj lava sai txias rau hauv pob zeb, nws tsis yog surprise tias basalt fibers muaj tshwj xeeb thermal rwb thaiv tsev, hluav taws kub tsis kam, thiab high-temperature stability. Cov khoom no ua rau lawv yog cov khoom siv rau cov rwb thaiv tsev kub. Piv txwv li, Lavxias teb sab basalt fiber ntau tsim Kamenny Vek muab US automotive kev lag luam nrog cov khoom siv rau cov pa hluav taws xob rwb thaiv tsev thiab muab cov ntaub ntawv kub-resistant rau kev siv.
Tshaj li kev ua haujlwm thermal, basalt fiber ntau's ua ke ntawm lub zog, nruj, cuam tshuam tsis kam, thiab Tshuaj inertness ua rau nws yog ib qho kev txhawb nqa txaus nyiam rau cov khoom sib xyaw. Hauv daim ntawv thov fiber-reinforced yas (FRP), nws cov txheej txheem molding zoo li cov iav fiber ntau. Yuav luag txhua cov iav fiber ntau molding txheej txheem tuaj yeem hloov kho rau basalt fiber nrog kev hloov me me rau qhov tseem ceeb. Basalt fiber kuj tau sib xws nrog txhua tus qauv resin systems.
Txawm hais tias basalt qhov ntom ntom (2.63 g / cm³) yog siab dua li iav fiber ntau, nws qhov kev ua tau zoo ua kom sib dua thiab ntau qhov sib xyaw ua ke.
Basalt fiber ntau thermal zog tau txais kev saib xyuas tshaj li rwb thaiv tsev. Nws cov composites tau nce siv hauv cov ntawv thov uas xav tau qhov kub thiab txias ntau dua. Nws cov kev cuam tshuam kuj ua tau zoo dua iav thiab carbon fibers. Cov kev tshawb fawb ua ntej los ntawm Lub Tebchaws Yelemees Lub Chaw Sib Koom Tes Sib Koom Tes thiab Lub Tsev Kawm Ntawv Textile Technology ntawm RWTH Aachen University tau pom tias basalt hybrid yarn fabric (HYWF)-reinforced polyamide 6 absorbs 35% ntau zog dua iav fiber ntau HYWF thiab 17% ntau dua carbon fiber HYWF.
Hlau thiab txhuas oxides nyob rau hauv basalt pab txhawb ntxiv qhov zoo. Piv txwv li, basalt fiber ntau pom zoo corrosion kuj thiab hluav taws kub retardancy dua E-iav. Ib txoj kev tshawb fawb los ntawm Ireland's Mafic thiab Canada's Fraunhofer Project Center tau lees paub tias basalt fiber ntau / epoxy test panels ua tiav 40% siab dua tensile modulus, tensile zog, thiab interlaminar shear lub zog, nrog rau 20% ntau dua qhov nruj, piv rau E-iav / epoxy panels ua nrog tib resin thiab txheej txheem. Kamenny Vek tau tshaj tawm cov txiaj ntsig zoo sib xws.
Basalt fiber ntauKev nqus dej tsawg yog qhov tseem ceeb rau kev tsim kho thiab kev siv kav dej. Nws yog non-conductive thiab, raws li ib txwm tshwm sim cov khoom, yooj yim rau recycle dua hluavtaws fibers - ib tug tseem ceeb kev xav rau automotive thiab lwm yam lag luam. Gencarelle piav qhia txog basalt fiber ntau li "leaner, greener, thiab tougher" dua li lwm txoj hauv kev, muab nws cov khoom sib xyaw ua tus choj ua haujlwm ntawm E-iav thiab carbon fiber. Raws li Thompson sau tseg, "Peb tab tom sau qhov sib txawv ntawm carbon thiab iav fibers-kev ua lag luam ntev txaus siab rau qhov kev daws teeb meem no."
Kev hloov ntawm cov pa roj carbon mus rau basalt fiber ntau tau tshaj tawm tias yooj yim dua li hloov los ntawm E-iav, txawm tias ob qho tib si ua tau. Rau cov neeg siv cov pa roj carbon fiber ntau, kev txuag nqi tsav tsheb ua haujlwm, thaum basalt qhov sib npaug ntawm kev ua tau zoo-rau-tus nqi piv rau cov ntawv thov uas carbon cov kev ua haujlwm siab tsis tsim nyog. Lawv cov hom kev ua tsis tiav kuj txawv: carbon fiber zoo li ua tsis tau zoo (xws li, tawg), thaum basalt fiber nthuav tawm maj mam, kev nyab xeeb dua. Streetman illustrates: "Ib tug carbon composite prosthetic ceg ua tsis tau tejyam, ua rau poob; ib tug basalt composite ceg tso cai rau tus neeg siv zaum."
Thaum kev txhim kho ntau lawm yog txo cov nqi, basalt fiber tseem tseem kim dua li E-iav hauv cov ntawv ntim siab. Txhawm rau ua kom pom tseeb tus nqi, nws cov khoom zoo tshaj plaws - siab zog, lub zog, kev cuam tshuam tsis zoo, tshuaj lom neeg / dej tsis kam, thiab kev nyab xeeb tsis ua haujlwm - yuav tsum xa cov nqi tseem ceeb. Raws li kev siv thev naus laus zis, pob zeb pob zeb volcanic no yog qhov tshwj xeeb hauv lub ntiaj teb ntawm cov khoom siv siab heev.
