Kev sib piv ntawm cov fiber ntau basalt thiab iav fiber txuas ntxiv
1 Txuas ntxiv mus Basalt Fiber hauv kev ua tau zoo ntawm cov txiaj ntsig
1) Lub zog thiab kub tsis kam: tas mus li basalt fiberlub zog tensile ntawm cov xov paj impregnated tuaj yeem ncav cuag ntau dua 2800 MPa, thaum lub Iav Fiber Feem ntau yog nyob ib ncig ntawm 2000 MPa, yog li ntawd, thaum siv cov khoom siv muaj zog siab, cov fiber basalt yuav tsum muaj qee qhov zoo dua hauv kev siv cov xwm txheej. Ntxiv rau, cov fiber basalt muaj qhov kub thiab txias zoo dua tuaj yeem tiv taus ntau dua 550 ℃ kom tswj tau qhov chaw kub thiab txias ruaj khov, thaum cov iav fiber ntawm qhov kub thiab txias ntau dua 500 ℃ yuav txo qhov ua tau zoo ntawm cov fiber. Tsis tas li ntawd,cov fiber basalt Lawv tiv taus kub tshaj 550 ° C, thaum cov iav fibers tsis muaj zog ntau ntawm qhov kub tshaj 500 ° C.
2) Qhov hnyav thiab qhov ceev: Qhov ceev ntawm cov iav fibers yog li 2.50 ~ 2.76 g / cm3 thaum lub zog ntawm cov fibers basalt yog me ntsis siab dua ntawm li 2.60 ~ 2.80 g / cm3Txawm hais tias cov fibers basalt muaj qhov ntom dua me ntsis, lawv lub zog siab dua thiab kev ua haujlwm ntev ua rau lawv zoo nkauj dua rau cov ntawv thov uas tsis muaj kev cuam tshuam rau pawg, xws li kev txhawb nqa cov qauv hauv cov tsev, tab sis qhov zoo tsis pom tseeb.
2 Kev sib piv ntawm tus nqi thiab cov txheej txheem tsim khoom
1) Tus nqi khoom siv raw: Cov khoom siv tseem ceeb rau cov iav fibers yog quartz xuab zeb, feldspar thiab limestone, uas pheej yig thiab muaj nyob rau hauv qhov ntau txaus, thaum basalt, cov khoom siv raw rau cov fiber basalt, yog pob zeb tawg ntuj uas muaj ntau heev, tab sis vim nws qhov kev faib tawm tau tawg ua ntau tus nqi khawb av thiab kev thauj mus los, thiab kev sib xyaw ua ke ntawm cov khoom siv raw, uas yog pob zeb ntuj muaj cov ntsiab lus sib txawv, kuj ua rau cov nqi nce ntxiv.
2) Qhov nyuaj ntawm cov txheej txheem tsim khoom: Cov txheej txheem tsim khoom ntawm cov fibers basalt nyuaj dua li cov iav fibers, uas twb tau tsim zoo thiab pheej yig dua los tsim ntawm qhov loj. Qhov sib piv, cov fibers basalt raug tsim ntawm qhov kub siab dua thiab xav tau cov khoom siv thiab cov txheej txheem nyuaj dua li cov iav fibers, uas tau tsim dav hauv cov kilns loj nrog lub kiln me me thiab lub monobloc crucible. Qhov no ua rau kev tsim khoom qis dua thiab kev ruaj khov qis dua ntawm cov khoom, cov nqi neeg ua haujlwm siab dua thiab kev siv zog ntau dua, thiab yog li cov nqi tsim khoom siab dua.
3 Kev lees txais thiab daim ntawv thov kev lag luam
Cov iav fiber txuas ntxiv thiab txuas ntxiv mus basalt fiber Raws li cov ntaub ntawv txhawb nqa muaj zog hloov tau. Tom qab ntau tshaj 20 xyoo kev txhim kho, cov iav fiber txuas ntxiv tau siv dav hauv ntau qhov chaw ntawm cov khoom sib xyaw ntawm ob qho tib si qib siab (kev tiv thaiv lub teb chaws thiab kev lag luam tub rog) thiab qib qis (cov ntaub ntawv tsim kho, cov khoom siv, thiab lwm yam). Txawm hais tias cov fiber basalt txuas ntxiv kuj tseem siv rau hauv kev lag luam kev tiv thaiv thiab tub rog, cov ntaub ntawv tsim kho, kev lag luam petrochemical, kev tsim khoom siv, thiab lwm yam, tab sis vim yog tus nqi tsim khoom siab dua, qee cov thev naus laus zis tseem ceeb tseem tsis tau kov yeej, hom khoom yog ib leeg thiab cov txheej txheem kev faib khoom tsis zoo tag nrho, thiab lwm yam, nws cov zis thiab feem ntawm kev ua lag luam qis dua li cov iav fiber.
