Kev sib piv kev tsom xam ntawm nruam basalt fiber ntau thiab iav fiber ntau

1 Nruam Basalt Fiber ntau hauv kev ua tau zoo ntawm qhov zoo

1) Lub zog thiab kub tsis kam: tsis tu ncua basalt fiber ntauimpregnated yarn tensile lub zog tuaj yeem ncav cuag ntau dua 2800 MPa, thaum lub iav Fiber Feem ntau yog nyob ib ncig ntawm 2000 MPa, yog li nyob rau hauv daim ntawv thov ntawm cov ntaub ntawv muaj zog yuav tsum tau basalt fibers qhia ib tug tej yam kom zoo dua nyob rau hauv daim ntawv thov ntawm scenarios Ntxiv rau, basalt fibers yog superior kub kuj yuav ua tau ntau tshaj 550 ℃ kom muaj ib tug ruaj khov high-temperature ib puag ncig, thaum lub iav fiber nyob rau hauv ib tug kub ntawm ntau tshaj 500 ℃ ntawm fiber ntau yuav txo tau. Ntxiv rau,basalt fibers Nws muaj peev xwm tiv taus qhov kub siab tshaj 550 ° C, thaum iav fibers tsis muaj zog ntawm qhov kub siab tshaj 500 ° C.

2) Mass thiab ntom: Qhov ntom ntawm iav fibers yog li 2.50 ~ 2.76 g / cm³ thaum qhov ceev ntawm basalt fibers yog me ntsis siab dua ntawm li 2.60 ~ 2.80 g / cm³Txawm hais tias basalt fibers yog me ntsis denser, lawv lub zog siab dua thiab ua haujlwm ntev ua rau lawv txaus nyiam rau cov ntawv thov uas tsis muaj qhov xav tau, xws li kev txhim kho hauv cov tsev, tab sis qhov zoo dua tsis pom tseeb.

2 Kev sib piv ntawm cov nqi thiab cov txheej txheem ntau lawm

1) Cov nqi ntawm cov 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 ntau txaus, whereas basalt, raw khoom rau basalt fibers, yog ib lub pob zeb volcanic ntuj uas muaj ntau, tab sis vim nws qhov kev faib tawm muaj cov mining siab thiab thauj cov nqi, thiab homogenization ntawm cov khoom siv raw, uas yog cov pob zeb ntuj muaj cov ntsiab lus sib txawv, kuj nce tus nqi.

2) complexity ntawm cov txheej txheem ntau lawm: Cov txheej txheem ntawm cov basalt fibers yog complex dua li cov iav fibers, uas yog twb tsim tau zoo thiab pheej yig dua los tsim nyob rau hauv loj teev. Nyob rau hauv sib piv, basalt fibers yog tsim nyob rau hauv siab melting kub thiab yuav tsum tau complex khoom thiab txheej txheem ntau tshaj li iav fibers, uas yog dav tsim nyob rau hauv loj kilns nrog ib tug me me kiln thiab ib tug monobloc crucible. Qhov no ua rau txo qis kev tsim khoom thiab kev ruaj ntseg ntawm cov khoom, cov neeg ua haujlwm ntau dua cov nqi thiab kev siv hluav taws xob ntau dua, thiab yog li cov nqi tsim khoom ntau dua.

3 Kev ua lag luam txais thiab daim ntawv thov teb

Nruam iav fiber ntau thiab tsis tu ncua basalt fiber ntau raws li cov ntaub ntawv txhawb zog muaj zog hloov pauv. Tom qab ntau tshaj 20 xyoo txoj kev loj hlob, nruam iav fiber ntau tau dav siv nyob rau hauv ntau yam kev sib xyaw ntawm ob qho tib si high-end (lub teb chaws tiv thaiv thiab tub rog kev lag luam) thiab qis kawg (cov ntaub ntawv tsim kho, cov khoom siv, thiab lwm yam). Txawm hais tias tsis tu ncua basalt fiber ntau kuj tseem siv rau hauv kev tiv thaiv thiab tub rog kev lag luam, cov khoom siv, kev lag luam petrochemical, khoom tsim, thiab lwm yam, tab sis vim yog cov nqi ntau lawm, qee qhov tseem ceeb thev naus laus zis tseem tsis tau kov yeej, cov khoom lag luam yog ib leeg thiab cov khoom faib tawm tsis zoo tag nrho, thiab lwm yam, nws cov txiaj ntsig thiab kev lag luam feem ntau qis dua li cov iav fiber ntau.
