Kev soj ntsuam ntawm Basalt Fiber Technology
Raw Materials thiab Production Process
Cov khoom siv raw rau basalt fiber ntau yog volcanic basalt pob zeb. Nws Tshuaj Muaj pes tsawg leeg yog feem ntau silicon dioxide thiab txhuas oxide, ntxiv los ntawm oxides ntawm hlau, calcium, thiab lwm yam. Tom qab crushing thiab tu, cov ore yog pub rau hauv ib tug melting rauv, qhov twg nws yog melted mus rau hauv ib tug homogeneous magma nyob rau hauv ib tug kub ntawm ib puag ncig. 1500 ° C, thiab ces kos rau hauv cov fibers tas li los ntawm platinum-rhodium alloy spinneret.
Piv rau iav Fiber,basalt fiber ntau tshem tawm cov txheej txheem batching thiab siv ntau cov khoom siv raw. Piv rau cov txheej txheem carbonization nyuaj ntawm carbon fiber, uas yuav tsum tau muaj cov organic precursor, nws cov txheej txheem ntau lawm yog ncaj qha. Txawm li cas los xij, kev hloov pauv hauv cov khoom sib xyaw ntawm basalt ore tuaj yeem cuam tshuam rau fiber ntau stability, yuav tsum tau soj ntsuam nruj raw khoom.
Cov yam ntxwv ntawm lub cev thiab tshuaj lom neeg ua haujlwm
(1) Mechanical Properties: Lub zog tensile ntawm basalt fiber ntau yog nruab nrab ntawm cov iav fiber ntau thiab carbon fiber, feem ntau yog li ntawm 3000 txog 4800 MPa, nrog rau elastic modulus ntawm kwv yees li 90-110 GPa. Qhov no yog superior rau E-iav fiber ntau tab sis qis dua high-modulus carbon fiber. Nws elongation ntawm so yog hais txog 3%, qhia ib theem ntawm toughness.
(2) Kub Resistance: Lub sijhawm ua haujlwm kub ntev yog -260 ° C txog 700 ° C, nrog rau qhov kub thiab txias tsis kam mus txog 1000 ° C. Qhov no yog superior rau feem ntau cov organic fibers thiab cov iav fibers zoo tib yam, mus txog ceramic fibers tab sis ntawm tus nqi qis.
(3) Corrosion Resistance: Nws ruaj khov nyob rau hauv cov kua qaub thiab alkali ib puag ncig zoo dua iav fiber ntau, tshwj xeeb tshaj yog qhia tias yuav luag tsis muaj corrosion nyob rau hauv pH 2-11 ntau yam, ua rau nws haum rau hnyav tej yam kev mob xws li dampness thiab ntsev tsuag.
(4) Lwm yam khoom: Nws muaj ib Tsawg thermal conductivity (kwv yees. ), zoo hluav taws xob rwb thaiv tsev kev ua tau zoo, thiab ib tug noo noo nqus tus nqi ntawm tsawg dua .
Kev sib piv ntawm daim ntawv thov teb
(1) Txhim kho kev tsim kho: Piv rau cov tsoos steel rebar, basalt fiber ntau yog lub teeb yuag thiab corrosion-resistant, uas zam qhov teeb meem ntawm cov pob zeb carbonation, txawm tias nws cov nqi pib yog siab dua. Piv rau carbon fiber rebar, nws muaj tus nqi zoo dua.
(2) Automotive Lightweighting: Nyob rau hauv cov khoom xws li nres pads thiab tso cua sov shields, nws yog ib puag ncig tus phooj ywg ntau tshaj li asbestos thiab ua tiav qhov hnyav ntawm dua. piv rau cov khoom siv hlau.
(3) Cov khoom siv hluav taws xob: Siv los ua cov khoom siv txhawb zog rau cov laug cam, nws qhov kev ua tau zoo dielectric zoo dua rau iav fiber ntau, thiab nws tsis txhob cuam tshuam cov teeb meem tiv thaiv.
(4) Cov khoom siv lim: Nws qhov kub-kub kuj ua rau nws muaj txiaj ntsig zoo dua cov tshuaj fiber ntau lim hauv thaj chaw ntawm qhov kub-kub flue roj pom.
Kev txwv
(1) Tus nqi tsim khoom: Tus nqi tam sim no ntawm basalt fiber ntau yog kwv yees li 2-3 npaug ntawm E-iav fiber ntau, feem ntau yog vim kev siv hluav taws xob siab melting thiab tseem ceeb spinneret hnav. Kev tsim khoom loj tuaj yeem txo qhov no mus txog 1.5 npaug ntawm cov iav fiber ntau.
(2) Txheej txheem tswj: Lub uniformity ntawm lub yaj ho cuam tshuam rau lub fiber inch, yuav tsum tau meej tswj ntawm qhov kub thiab txias qhov chaw ntawm daim duab.
(3) Deep Processing Adaptability: Kev xaiv ntawm cov neeg ua haujlwm sib txuas rau kev sib txuas nrog cov matrices resin yog nruj dua li cov iav fiber ntau, xav tau kev ua kom zoo dua qub.
Kev Tsim Kho Kev Lag Luam
(1) Raw Material Purification Technology: Siv txoj hauv kev xws li sib nqus sib nqus thiab flotation los txo cov ntsiab lus hlau hauv cov ore, yog li txhim kho yaj stability.
(2) Melting txheej txheem txhim kho: Tsim tshiab electrode-rhuab kilns kom txo tau lub zog noj los ntawm txog piv rau cov tsoos roj tua hluav taws.
(3) Product Diversification: Tshwj xeeb ntau yam xws li ultra-fine fibers (ib txoj kab uas hla filament ) thiab cov fibers uas tsis yog lub voj voog hla ntu tau tsim.
(4) Recycling: Cov khib nyiab fibers tuaj yeem crushed thiab siv raws li admixtures nyob rau hauv pob zeb, ua tiav cov peev txheej ncig.
Xaus
Piv nrog rau lwm cov fibers ua haujlwm siab, qhov tseem ceeb ntawm qhov zoo basalt fiber ntau nyob rau hauv nws tag nrho-natural raw khoom system thiab sib npaug kev ua tau zoo. Txawm hais tias nws lub zog paub tsis yog siab npaum li cov pa roj carbon fiber ntau, thiab nws qhov ntsuas kub qis dua li ceramic fiber, nws cov phooj ywg ib puag ncig thiab tus nqi-zoo ua rau nws hloov tsis tau hauv ntau yam kev lag luam. Nrog kev txhim kho txuas ntxiv ntawm cov txheej txheem ntau lawm, nws cov kev siv ntau yam yuav tsum tau nthuav dav ntxiv.
