Hauv cov yam ntxwv tshwj xeeb twg yog cov yam ntxwv ntawm "kev tiv taus kub siab" ntawm cov fiber basalt?

1. Kev Pab Cuam Kub Ntev thiab Qhov Chaw Mos.

Qhov kub thiab txias uas muaj kev nyab xeeb rau kev siv mus sij hawm ntev rau tus qauv basalt fiber feem ntau poob ntawm -260 ° C thiab + 650 ° C. Txawm li cas los xij, rau cov qib kub-resistant-kub-tsim los ntawm kev ua kom zoo dua qub thiab kev hloov kho cov txheej txheem-qhov txwv sab saud ntawm qhov kub thiab txias mus sij hawm ntev tuaj yeem nce ntxiv. Nws qhov softening point-qhov kub uas lub fiber pib deform-tuaj yeem mus txog lossis tshaj 900 ° C. Qhov no txhais tau tias, hauv qab qhov kub thiab txias no, lub fiber tuaj yeem tswj tau qhov ruaj khov ntawm nws lub cev thiab cov khoom siv kho tshuab.

2. Lub zog khaws cia ntawm qhov kub siab.

Ib qho tseem ceeb rau kev ntsuam xyuas qhov kub ntawm cov fiber yog qhov uas nws khaws nws lub zog hauv qhov chaw kub siab. Zoo, cov fibers basalt uas tiv taus kub heev feem ntau qhia txog lub zog tensile siab txawm tias tom qab raug rau qhov chaw ib puag ncig ntev txog ntau pua degrees Celsius, yog li qhia tau tias muaj kev tiv thaiv zoo rau kev laus thermal. Qhov sib piv, ntau cov organic fibers yuav tau ntev txij li thaum decomposed lossis yaj ntawm qhov kub zoo li no.

3. Kev Ruaj Ntseg Thermal thiab Kev Ua Haujlwm Thermal Qis.

Cov fiber basaltyog ib qho zoo heev ntawm Kev rwb thaiv tsev kub cov khoom siv, uas muaj cov thermal conductivity tsawg. Thaum kub siab, nws tsis hlawv lossis tso cov pa lom, thiab nws tswj tau cov tshuaj lom neeg ruaj khov. Qhov kev ruaj khov thermal no ua rau nws muaj qhov zoo hauv kev rwb thaiv tsev kub.

Tej zaum ib tug neeg yuav nug tias: Muab hais tias muaj ntau yam khoom siv uas tiv taus kub thiab txias muaj nyob rau hauv xwm thiab kev lag luam—xws li cov fibers ceramic thiab cov fibers iav—yuav ua li cas thiaj ua tau li ntawd? Basalt Cov fiber txawv ntawm lwm cov? Qhov no yog ib lo lus nug zoo heev, thiab kev tshuaj xyuas sib piv pab kom meej meej txog cov yam ntxwv tshwj xeeb ntawm cov fiber basalt uas tiv taus kub siab.

Piv rau cov E-iav fiber ntau, cov basalt fiber qhia tau tias nws tiv taus kub zoo dua. Qhov kub thiab txias ntev ntawm E-iav fiber feem ntau tsis tshaj 350 ° C, thaum lub peev xwm tiv taus kub ntawm basalt fiber yuav luag ob npaug ntawm tus lej ntawd. Thaum piv rau cov khoom siv ua los ntawm cov khoom siv aluminium silicate ceramic, cov basalt fiber uas tiv taus kub siab yuav muaj qhov kub thiab txias qis dua me ntsis; txawm li cas los xij, nws muaj lub zog zoo dua, nqus dej noo tsawg dua, thiab tiv taus tshuaj lom neeg xeb - tshwj xeeb tshaj yog nyob rau hauv cov chaw alkaline. Ntxiv mus, vim tias basalt fiber yog los ntawm cov pob zeb ntuj, nws cov txheej txheem tsim khoom siv hluav taws xob tsawg thiab vam khom cov khoom siv raw khoom ntau heev, yog li ua rau nws muaj txiaj ntsig zoo hauv kev siv nyiaj thiab kev ruaj khov. Nws yog vim muaj cov yam ntxwv no uas cov basalt fiber uas tiv taus kub siab tau pom ntau daim ntawv thov thoob plaws ntau lub lag luam. Lawv qhov kev siv tsis yog tsuas yog ua tau zoo hauv ib qho kev ua tau zoo xwb, tab sis ua lub luag haujlwm tseem ceeb hauv cov xwm txheej uas ntau yam kev xav tau - xws li kev tiv taus kub siab, kev rwb thaiv tsev thermal, kev tiv thaiv hluav taws, thiab kev txhawb nqa cov qauv - yog sib xyaw ua ke.
