Cov yam tseem ceeb uas cuam tshuam rau kev npaj cov fibers basalt
Raws li ib tug natural mineral, nws yog ib qho tseem ceeb hauv kev kho mob. Tshuaj lom neeg kev sib xyaw thiab kev sib xyaw ua ke sab hauv ntawmCov khoom siv basalttxawv heev. Qhov kub yaj nce nrog cov ntsiab lus ntawm quartz thiab plagioclase feldspar (calcium feldspar thiab sodium feldspar) tab sis txo qis nrog cov ntsiab lus ntawm pyroxene (tremolite thiab ultramafic). Hauv kev npaj, cov khoom siv hauv av maj mam yaj, cov qauv siv lead ua kom raug rau hauv cov qauv iav amorphous, cov khoom siv ore tsis sib xws yuav ua rau tsis txaus yaj, tsis sib xws yaj, kev ua haujlwm yaj qis, tsis yaj tag nrho hauv cov xwm txheej ntawm cov dej nag yooj yim ntawm cov siv lead ua, feem ntau yog qhov tshwm sim ntawm cov filaments tawg, cuam tshuam rau lub zog tensile ntawm cov fibers, qhov zoo ntawm cov khoom thiab kev ua tau zoo. Ntawm qhov ntsuas me me, tom qab tsoo cov basalt ore yaj iav lub cev tsis sib xws ntawm lub thaiv tau pom hauv Daim Duab A; Basalt Fiber Qhov morphology ntawm qhov chaw yog cylindrical, thiab du, tsis muaj qhov tawg thiab cov khoom txuas raws li pom hauv Daim Duab B. Hauv cov txheej txheem ntawm cov fiber fibers, qhov kub ntawm 1,350 ~ 1450 ℃, nrog rau qhov nce ntawm qhov kub, lub fiber txoj kab uas hla, nag lossis daus ntawm cov siv lead ua kom txo qhov ntau ntawm cov fiber zog nce thiab mus txog nws qhov siab tshaj plaws hauv 1390 ℃; basalt ore homogenization lub sijhawm ntawm 0 ~ 1450 ℃, qhov kub ntawm 1,350 ~ 1450 ℃, lub fiber txoj kab uas hla nce, nag lossis daus ntawm cov siv lead ua kom txo qhov ntau ntawm cov fiber zog nce thiab mus txog nws qhov siab tshaj plaws hauv 1390 ℃; basalt Ore homogenization lub sijhawm 0 ~ 25h, thaum homogenization ntawm 5h thaum lubbasalt fiber Lub zog tau mus txog qhov zoo tshaj plaws, nrog lub sijhawm homogenization thiab tom qab ntawd nthuav dav, qib polymerization ntawm cov qauv fiber nce siab, lub cheeb ntawm fiber me dua, txo qhov tshwm sim ntawm cov kab nrib pleb tsim los ntawm cov fiber, thiab lub zog fiber ntau zuj zus.
Cov khoom siv tseem ceeb, lub cub tawg, lub qhov av qis, thiab daim ntawv xau, kuj cuam tshuam rau kev npaj cov fibers basalt. Thaum cua sov, thaum nws yaj, cov hlau oxides denser raug thauj mus rau hauv qab ntawm lub cub tawg thiab ua rau cov ntawv xau nplua nuj, uas ua rau daim ntawv xeb. Feem ntau, lub neej ua haujlwm ntawm daim ntawv me me yog 9 lub hlis thiab daim ntawv loj dua yog 11 lub hlis. Nws tau hais tias kev pleev xim rau saum npoo ntawm daim ntawv xau nrog cov neeg sawv cev kho tshwj xeeb yuav muaj txiaj ntsig zoo dua, tab sis hom neeg sawv cev kho, koob tshuaj, thiab txoj kev siv tseem yuav tsum tau sim thiab tsim.
Cov neeg sawv cev impregnating tuaj yeem siv rau kev kho qhov chaw ntawm basalt fibers, yog kom ua tiav qhov kev ua tau zoo tshwj xeeb ntawm cov fiber basalt, cov thev naus laus zis tseem ceeb, qhov zoo ntawm cov fiber nws tus kheej, thiab cov ntaub ntawv sib xyaw ua ke tom qab ntawd muaj qhov cuam tshuam tseem ceeb rau cov khoom siv lub cev thiab tshuaj lom neeg. Kev siv tam sim no ntawm tus neeg sawv cev infiltration, feem ntau ntawm kev siv rau cov iav fiber infiltration agent formulations, feem ntau siv ntau yam ntawm epoxy resin emulsion chav kawm, thiab yav tom ntej kev txhim kho ntawm tus neeg sawv cev infiltration tshwj xeeb rau basalt fibers, yuav muaj lub luag haujlwm tseem ceeb hauv kev txhawb nqa kev txhim kho thiab daim ntawv thov ntawm kev lag luam.
