Kev cuam tshuam ntawm qhov tsis ruaj khov basalt raw khoom muaj pes tsawg leeg ntawm cov khoom tsim thiab kev txhim kho tiag tiag

2025-06-20

Zoo ib yam li carbon fiber thiab iav Fiber, zus tau tej cov basalt fiber ntau yuav tsum raw khoom standardization. Muaj qhov sib txawv tseem ceeb hauv qhov zoo thiab daim ntawv thov cuam tshuam ntawm basalt fiber ntau los ntawm ntau cheeb tsam. Txawm nyob rau hauv tib cheeb tsam, variations muaj nyob rau hauv basalt los ntawm ntau qhov chaw ntawm tib mine.

Hauv kev xyaum, peb qhov teeb meem tseem ceeb tau raug txheeb xyuas:

(1) Qee cov basalt ore raw cov ntaub ntawv muaj qhov nqaim qhov ntsuas kub, uas yog ze rau qhov kub ntawm crystallization. Cov ntaub ntawv nyoos zoo li crystallize tam sim ntawd thaum kos duab, rhuav tshem fiber ntau txuas ntxiv thiab txo lub zog tensile.

(2) Qee cov khoom siv basalt ore raw cov ntaub ntawv muaj ntau qhov kub-kub resistant crystalline hais, xws li olivine thiab corundum, ua rau nws nyuaj kom tau ib homogeneous yaj.

(3) Cov Tshuaj muaj pes tsawg leeg ntawm cov khoom sib txawv ntawm basalt ore raw cov ntaub ntawv sib txawv, uas cuam tshuam rau kev ruaj ntseg ntawm kev ua tau zoo ntawm cov basalt fibers txuas ntxiv tsim.

Txhawm rau daws qhov tsis ruaj khov ntawm cov khoom siv raw, raws li cov lus hais saum toj no, cov kev ntsuas hauv qab no tuaj yeem raug coj los txhim kho:

Xaiv cov khoom zoo basalt ore raw khoom. Basalt ore yuav tsum yog homogeneous, muaj qib qis ntawm crystallization, tsis muaj phenocrysts loj, ob peb fissures, tsis tshua muaj huab cua, thiab tsis muaj lwm impurities xws li quartz thiab chert. Cov tshuaj muaj pes tsawg leeg ntawm basalt ore yuav tsum nyob rau hauv ib qho kev tsim nyog. Tsis tas li ntawd, nws yuav tsum muaj qhov tsim nyog acidity coefficient ( $M_{a}$ ) nyob rau hauv ntau yam ntawm $3.5 \sim 5.8$ , thiab viscosity ( $l g los yog$ ) ntawm $0.5 \sim 1.4 Zoo \cdot s$ . Lub viscosity ( $los yog$ ) ntawm silicate melts yog qhov ua haujlwm ntawm qhov kub, siab, thiab muaj pes tsawg leeg, thiab tuaj yeem sawv cev los ntawm Arrhenius kab zauv: $l g los yog = l g los yog_{0} + THIAB_{los yog} / RT$ , qhov twg $los yog_{0}$ yog qhov tsis tu ncua (pre-exponential factor) thiab $THIAB_{los yog}$ yog lub zog ua kom muaj kuab paug rau cov yaj. Basalt ore yuav tsum muaj ntau qhov kub thiab txias thaum lub sij hawm tsim cov txheej txheem, uas ua rau melting thiab kos duab kuj yooj yim, thiab nws yuav tsum muaj zoo tsis muaj kub-resistant crystalline hais xws li olivine thiab corundum.
Ntxiv dag zog rau raw khoom homogenization. Cov ntaub ntawv raw uas tsim nyog tau raug crushed, tshuaj ntsuam, thiab homogenized siv cov cuab yeej tshwj xeeb ua ntej xa mus rau pre-kiln silo. Txhawm rau kom ntseeg tau qhov zoo ntawm cov khoom siv ore raw, qhov loj me yuav tsum tau khaws cia kom zoo ib yam. Cov khoom loj dhau tuaj yeem ua rau muaj teeb meem melting, thaum cov khoom me me tuaj yeem txo qhov zoo ntawm cov yaj.
Muab cov khoom zoo basalt ore raw khoom. Vim lub complex muaj pes tsawg leeg ntawm tej yam ntuj tso basalt ore, nrog ntau yam minerals txuam thiab coexisting, thiab cov minerals sib txawv muaj txawv cov ntsiab lus melting, seb cov khoom raw yog homogeneous tag nrho yog ib qho kev txiav txim siab cuam tshuam rau cov txiaj ntsig ntawm kev kos duab. Yuav kom yaj cov khoom zoo dua qub thiab txhim kho kev ruaj ntseg ntawm cov fiber ntau qhov kev ua tau zoo, qee lub tuam txhab tsim khoom tau siv txoj kev "artificial batching", qiv los ntawm iav fiber ntau. Qhov no suav nrog kev npaj cov khoom siv raw raws li cov qauv, xaiv cov khoom zoo siab ntshiab ntuj basalt, thiab kho nws raws li tus qauv tsim nyog siv "siv dab tsi uas ploj lawm" thiab "ntshiab rau ntshiab" mus kom ze - piv txwv li, ntxiv calcium yog tias nws tsis txaus. Tsis tas li ntawd, rau cov khoom uas muaj kev ua tau zoo tshwj xeeb, kev hloov kho doping tuaj yeem ua kom ntseeg tau tias txhua qhov kev ua tau zoo raws li cov qauv tsim, xws li alkali-resistant fibers, high-temperature resistant fibers, thiab high-strength, high-modulus fibers. Qhov no yuav tsum tau xaiv cov khoom siv ib leeg ib leeg lossis lwm yam basalt ores kom tsim nyog "doping modification" ntawm cov khoom siv raw basalt.
