Cov yam ntxwv cuam tshuam rau kev npaj ntawm basalt fibers
Raws li ib tug natural ore nyob rau hauv cov xwm, lub Tshuaj muaj pes tsawg leeg thiab internal crystallization ntawmbasalt raw khoomtxawv heev. Lub melting kub nce nrog cov ntsiab lus ntawm quartz thiab plagioclase feldspar (calcium feldspar thiab sodium feldspar) tab sis txo nrog cov ntsiab lus ntawm pyroxene (tremolite thiab ultramafic). Hauv kev npaj, cov pob zeb hauv av maj mam yaj, cov qauv siv lead ua rau hauv cov qauv iav amorphous, cov khoom siv tsis sib xws yuav ua rau tsis txaus melting, tsis sib xws, melting efficiency tsawg, tsis tag melted nyob rau hauv cov ntaub ntawv ntawm yooj yim nag lossis daus ntawm crystals, feem ntau tshwm sim ntawm tawg filaments, cuam tshuam lub tensile lub zog ntawm cov fibers, qhov zoo ntawm cov khoom thiab kev ua tau zoo. Ntawm cov nplais me me, tom qab crushing lub basalt ore yaj lub iav lub cev tsis xwm yeem ntawm qhov thaiv yog pom hauv daim duab A; Basalt Fiber ntau deg morphology yog cylindrical, thiab du, tsis muaj qhov pom tseeb tawg thiab txuas raws li qhia hauv daim duab B. Nyob rau hauv cov txheej txheem ntawm fiber ntau, qhov kub ntawm 1,350 ~ 1450 ℃, nrog rau qhov kub thiab txias, qhov fiber ntau txoj kab uas hla, nag lossis daus ntawm crystals kom txo cov fiber ntau zog thiab mus txog nws cov nqi siab tshaj plaws hauv 1390 ℃; basalt ore homogenization lub sij hawm ntawm 0 ~ 1450 ℃, qhov kub ntawm 1,350 ~ 1450 ℃, fiber ntau txoj kab uas hla nce, nag lossis daus ntawm crystals kom txo cov fiber ntau zog thiab mus txog nws cov nqi siab tshaj plaws nyob rau hauv 1390 ℃; basalt Ore homogenization lub sij hawm 0 ~ 25h, thaum homogenization ntawm 5h thaum lubbasalt fiber ntau lub zog tau mus txog lub xeev zoo tshaj plaws, nrog rau lub sijhawm homogenization thiab txuas ntxiv mus, cov qauv fiber ntau polymerization degree nce, fiber ntau txoj kab uas hla yuav me dua, txo qhov tshwm sim ntawm cov kab nrib pleb uas tsim los ntawm fiber ntau, lub zog fiber ntau yog ib qho kev nyiam tuaj.
Cov khoom siv tseem ceeb, lub qhov cub, lub cellar, thiab cov ntawv xau, kuj cuam tshuam rau kev npaj ntawm basalt fibers. Thaum rhuab, raws li nws melts, cov denser hlau oxides yog thauj mus rau hauv qab ntawm lub kiln thiab ua enriched nyob rau hauv cov ntaub ntawv to, uas nyob rau hauv lem erodes daim ntawv. Feem ntau, kev pab cuam lub neej ntawm ib daim ntawv me me yog 9 lub hlis thiab cov ntawv loj dua yog 11 lub hlis. Nws tau raug pom zoo tias txheej txheej ntawm cov ntawv xau nrog tus neeg saib xyuas tshwj xeeb tuaj yeem muaj txiaj ntsig zoo, tab sis hom kev kho tus neeg saib xyuas, ntau npaum li cas, thiab cov txheej txheem ntawm daim ntawv thov tseem yuav tsum tau sim thiab tsim.
Impregnating cov neeg sawv cev tuaj yeem siv rau kev kho deg ntawm basalt fibers, yog kom ua tiav qhov kev ua haujlwm tshwj xeeb ntawm basalt fibers, cov thev naus laus zis thev naus laus zis, qhov zoo ntawm fiber ntau nws tus kheej, thiab cov ntaub ntawv sib xyaw ua ke muaj qhov cuam tshuam tseem ceeb rau lub cev thiab tshuaj lom neeg. Kev siv tam sim no ntawm tus neeg saib xyuas infiltration, feem ntau ntawm kev siv cov iav fiber ntau infiltration tus neeg sawv cev formulations, feem ntau siv ntau yam ntawm epoxy resin emulsion chav kawm, thiab kev txhim kho yav tom ntej ntawm infiltration agent tshwj xeeb tshaj yog rau basalt fibers, yuav muaj lub luag haujlwm tseem ceeb hauv kev txhawb kev txhim kho thiab kev siv hauv kev lag luam.
