Basalt Fiber
Basalt Fiber yog qhov kev sib tw tas mus li ntawm ntuj hauv qab. Nws yog basalt pob zeb nyob rau hauv 1450 ℃ ~ yaj, los ntawm platinum-lidium alloy hlau-ceev rub tawm ua los ntawm fiber ntau. Cov xim ntawm cov ntshiab ntuj ntuj basalt fiber ntau yog ntau xim av. Basalt Fiber yog ib hom tshiab ntawm inorganic ib puag ncig ntsuab siab-caluminide fiber ntau, alumium oxide, hlau oxide, hlau oxide, hlau oxide thiab titanium dioxide thiab lwm yam oxide.Basalt Nraum NruamTsis tsuas yog muaj lub zog siab, tab sis kuj muaj ntau yam khoom muaj ntau yam xws li cov rwb thaiv tsev hluav taws xob, xeb tsis kam, kub tsis kam thiab. Tsis tas li ntawd, cov txheej txheem ntau lawm ntawm basalt fiber txiav txim siab los tsim cov khoom pov tseg, tsis muaj kev phom sij, yog li cov khoom lag luam zoo tiag tiag. Basalt cov fiber ntau tau siv nyob rau hauv fiber ntau siv cov khoom siv, cov ntaub ntawv sib tw, cov khoom lag luam roj hmab, cov chaw tiv thaiv thiab tiv thaiv kub.
Cov yam ntxwv
① Cov Khoom Siv Raw Txaus
Basalt Fiberyog ua los ntawm basalt melted thiab kos, thiab basalt ore nyob rau lub ntiaj teb thiab lub hli yog cov nqi khoom siv yog tsawg.
② Ib puag ncig cov khoom uas phooj ywg zoo
Basalal ore yog cov khoom siv ntuj, tsis muaj boron lossis lwm cov tshuaj alkali uas muaj kev phom sij, yog li tsis muaj cov pa luam yeeb, cov cua yuav tsis ua rau muaj kuab paug. Ntxiv mus, cov khoom muaj lub neej ntev, yog li nws yog hom tshiab ntsuab nquag muaj kev tiv thaiv cov khoom siv tsawg, kev ua tau zoo thiab kev nyiam huv zoo.
③ Kub thiab Dej Kuj
Nruam booction fiber ntau ntau yog feem ntau yog feem ntau 269 ~ 700 ℃ (softing qhov kub ntawm carbon fiber ntau tuaj yeem tsuas ncav 500 ℃. Tshwj xeeb, basalt fiber ntau nyob rau hauv 600 ℃ ua haujlwm, nws lub zog tom qab kev so kuj tseem tuaj yeem tswj 80% ntawm lub zog qub; Ua haujlwm ntawm 860 ℃ yam tsis muaj shrinkage, txawm hais tias kub tsis kam muaj cov ntxhia cov ntaub plaub me ntsis nyob rau lub sijhawm 50% -60%, iav wool yog tag nrho. Carbon fiber ntawm txog 300 ℃ ntawm Co thiab CO2 ntau lawm. Basalt fiber ntawm 70 ℃ nyob rau hauv kev txiav txim ntawm dej kub tuaj yeem tswj lub zog siab, basalt fiber ntau hauv 1200 h yuav plam ib feem ntawm lub zog.
④ Cov tshuaj zoo ruaj khov thiab corrosion tsis kam
Nruam booction fiber muaj K2O, Mgo) thiab lwm yam) thiab lwm yam los txhim kho cov tshuaj lom neeg thiab dej ua ke tau txais txiaj ntsig zoo, ua si ncaj ncees txoj haujlwm ncaj ncees. Nws yog qhov zoo dua piv nrog cov tshuaj ruaj khov ntawm cov iav fibers, tshwj xeeb tshaj yog nyob rau hauv alkaline xov xwm kuj tseem tuaj yeem tswj hwm qhov kev ua tau zoo rau alkali corrosion.

⑤ modulus ntawm elasticity thiab tensile lub zog
Cov modulus ntawm elasticity ntawm basebal fiber yog 9100 kg / mm-mm, asbidso giber, aramid fiber ntau thiab silica fiber. Lub zog tensile ntawm basalt fiber ntau yog 3800-4800 MPA, uas yog siab dua li ntawm cov roj loj, roj av, roj alumina, thiab sib piv nrog cov fiber ntau. Basalt Fiber muaj qhov ntom ntom ntawm 2.65-3.00 g /9 degrees ntawm 5-9 degrees ntawm mohs haroction nplai, yog li nws muaj tensile requement properties. Nws cov neeg kho tshuab muaj zog tshaj li ntawm cov khoom ntuj thiab cov khoom siv hluavtaws zoo nkauj, thiab nws yog qhov ua ntej ntawm plaub qhov kev ua tau zoo siab.
Suab Zoo Tshaj Rwb Thaiv Tsev
Nruam basalt fiber ntau muaj suab zoo nkauj rwb thaiv tsev, kev ua kom haum lub suab sib nqus, nrog qhov nce hauv ntau lub suab sib txawv, nws tau nqus cov coefficient nce ntau. Xws li kev xaiv ntawm txoj kab uas hla 1-3μm bionalt fiber ntau ua los ntawm (ntom khoom siv tau, hauv lub suab rau 100-32,5, 0.22 ~ 0.25 thiab 0.93, feem.
⑦ Zoo Hnub Dielectric cov yam ntxwv
Lub ntim resistivity ntawm nruam basalt fiber ntau yog ib qho kev txiav txim ntawm qhov ntau dua li ntawd ntawmE iav fiber, uas muaj cov khoom Dielectric zoo heev. Txawm hais tias cov basalt ore muaj feem ntau feem ntawm 0.2 ntawm kev coj ua tshwj xeeb deligent ntawm cov fiber ntau dua li cov fiber ntau dua li cov fiber ntau

Ntuj Cua Sov
Zoo dispersion nrog cov cement thiab pob zeb ua, sib raug zoo, sib xws li coefficient ntawm thermal expansion thiab condaction, huab cua zoo tsis kam.
⑨ Kev nqus tau qis dua
Kev nqus dej noo ntawm cov hauv paus basalt yog tsawg dua 0.1%, qis dua li aramid fiber, pob zeb tsiaj thiab asbestos.
⑩ qis dua thermal conductivity
The thermal conductivity of basalt fiber is 0.031 W/mK – 0.038 W/mK, which is lower than that of aramid fiber, alumino-silicate fiber, alkali-free glass fiber, rockwool, silicon fiber, carbon fiber and stainless steel.

Iav yas
Cov ntaub ntawv fiberglass, ib qho khoom siv tsis zoo nkauj nrog cov kev ua tau zoo, muaj zog kho cua sov, tab sis qhov tsis zoo yog nkig ua kom tsis kam. Nws yog raws li chlorite, quartz xuab zeb, limestone, boron calcium pob zeb rau ntau dua 20 / 20-1 / 5, txhua ntu ntawm fiber ntau filaments yog ntau pua lossis txawm tias ntau txhiab tus monofilament muaj pes tsawg.Iav yasFeem ntau yog siv los ua cov khoom siv uas txhawb ntxiv hauv cov khoom siv sib xyaw, cov hluav taws xob cov ntaub ntawv hluav taws xob thiab cov rooj tsav tsheb hluav taws xob thiab lwm yam ntawm kev lag luam hauv tebchaws.

Khoom Siv Khoom
Melting taw tes: iav yog hom tsis-crystalline, tsis muaj qhov tseeb melting point, nws yog feem ntau ntseeg hais tias qhov muag muag muag ntawm 500 ~ 750 ℃.
Boint Taw tes: Txog 1000 ℃
Qeeb: 2.4 ~ 2.76 g / cm3
Thaum cov iav fiber ntau yog siv los ua cov khoom siv kom txhawb kom muaj kev txhawb nqa, qhov tseem ceeb tshaj plaws yog nws lub zog siab. Tensile lub zog hauv lub xeev txheem yog 6.3 ~ 6. 6. 6. 6. 6. 6. 6. Thaum tshav kub ua tau yog qhov zoo, qhov kub thiab txias txog 300 ℃ ntawm lub zog ntawm tsis muaj txiaj ntsig. Nws muaj rwb thaiv hluav taws xob zoo, yog cov ntaub ntawv hluav taws xob siab ntawm hluav taws xob, tseem siv rau cov ntaub ntawv rwb thaiv tsev thiab cov ntaub thaiv hluav taws. Feem ntau tsuas yog corroded los ntawm concentrated alkali, hydroflofluoric acid thiab concentrated phosphoric acid.
