Qhov cuam tshuam ntawm cov khoom siv raw basalt tsis ruaj khov rau kev tsim khoom tiag tiag thiab kev ntsuas kev txhim kho

2025-06-20

Zoo ib yam li cov carbon fiber thiab Iav Fiber, kev tsim cov fiber basalt txuas ntxiv mus yuav tsum tau ua raws li cov khoom siv raw. Muaj qhov sib txawv tseem ceeb hauv qhov zoo thiab cov txiaj ntsig ntawm cov khoom siv fiber basalt los ntawm thaj chaw sib txawv. Txawm tias nyob hauv tib cheeb tsam, muaj kev hloov pauv hauv basalt los ntawm ntau qhov chaw ntawm tib lub mine.

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

(1) Qee cov khoom siv raw ntawm basalt ore muaj qhov kub thiab txias nqaim, uas ze heev rau qhov kub ntawm crystallization. Cov khoom siv raw no feem ntau yuav crystallize tam sim ntawd thaum kos, ua rau puas tsuaj rau cov fiber continuity thiab txo qhov muaj zog tensile.

(2) Qee cov khoom siv raw ntawm basalt ore muaj cov khoom siv crystalline uas tiv taus kub ntau, xws li olivine thiab corundum, ua rau nws nyuaj rau kom tau txais cov khoom sib xyaw ua ke.

(3) Lub Tshuaj lom neeg Cov khoom sib txawv ntawm cov khoom siv basalt ore raw sib txawv, uas cuam tshuam rau kev ruaj khov ntawm kev ua tau zoo ntawm cov fibers basalt tas mus li.

Yuav kom daws tau qhov tsis ruaj khov ntawm cov khoom siv raw, raws li cov ntsiab lus tau hais los saum toj no, cov kev ntsuas hauv qab no tuaj yeem ua rau kev txhim kho:

Xaiv cov khoom siv basalt ore zoo. Cov pob zeb basalt yuav tsum yog homogeneous, muaj qib qis ntawm crystallization, tsis muaj phenocrysts loj, ob peb qhov tawg, tsis tshua muaj huab cua, thiab tsis muaj cov khoom tsis huv sab nraud zoo li quartz thiab chert. Cov tshuaj lom neeg ntawm cov pob zeb basalt yuav tsum nyob hauv qhov ntau thiab tsawg tsim nyog. Tsis tas li ntawd, nws yuav tsum muaj cov coefficient acidity tsim nyog ( $M_{ib}$ ) nyob rau hauv qhov ntau ntawm $3.5 \sim 5.8$ , thiab viscosity ( $l g los yog$ ) ntawm $0.5 \sim 1.4 Zoo \cdot s$ Qhov viscosity ( $los yog$ ) ntawm silicate melts yog ib qho kev ua haujlwm ntawm qhov kub, siab, thiab cov khoom sib xyaw, thiab tuaj yeem sawv cev los ntawm Arrhenius equation: $l g los yog = l g los yog_{0} + THIAB_{los yog} / RT$ , qhov twg $los yog_{0}$ yog ib qho tsis hloov pauv (pre-exponential factor) thiab $THIAB_{los yog}$ yog lub zog ua kom muaj zog ntawm cov dej ntws viscous rau cov yaj. Basalt ore yuav tsum tswj tau qhov kub thiab txias ntau thaum lub sijhawm kos duab, uas ua rau yaj thiab kos duab yooj yim heev, thiab nws yuav tsum tsis muaj cov khoom siv crystalline uas tiv taus kub siab xws li olivine thiab corundum.
Txhawb kom cov khoom siv raw homogenization. Cov khoom siv raw uas tsim nyog raug tsoo, tshuaj xyuas, thiab sib xyaw ua ke siv cov cuab yeej tshwj xeeb ua ntej xa mus rau lub silo ua ntej kiln. Yuav kom ntseeg tau tias cov khoom siv raw ore zoo, qhov loj ntawm cov khoom me me yuav tsum tau khaws cia kom sib xws. Cov khoom me me loj dhau tuaj yeem ua rau muaj teeb meem yaj, thaum cov khoom me me dhau tuaj yeem txo qhov zoo ntawm cov khoom yaj.
Sib tov cov khoom siv zoo basalt ore raw. Vim yog cov khoom sib xyaw ua ke ntawm cov pob zeb basalt ntuj, nrog rau ntau yam minerals sib txuas thiab sib koom ua ke, thiab cov minerals sib txawv muaj cov ntsiab lus yaj sib txawv, seb cov khoom siv raw puas sib xws yog ib qho ntawm cov yam tseem ceeb uas cuam tshuam rau qhov tshwm sim ntawm kev kos duab. Txhawm rau kom yaj cov khoom zoo dua thiab txhim kho qhov ruaj khov ntawm cov fiber ua tau zoo, qee lub tuam txhab tsim khoom tau siv txoj kev "ua kom sib xyaw ua ke", qiv los ntawm kev tsim cov iav fiber. Qhov no suav nrog kev npaj cov khoom siv raw raws li cov qauv, xaiv cov basalt ntuj zoo, thiab kho nws raws li cov nqi txheem siv txoj hauv kev "muab cov khoom uas ploj lawm" thiab "ntshiab rau ntshiab" - piv txwv li, ntxiv calcium yog tias nws tsis txaus. Tsis tas li ntawd, rau cov khoom lag luam uas muaj cov kev cai ua tau zoo tshwj xeeb, kev hloov kho doping xaiv tuaj yeem ua tiav kom ntseeg tau tias txhua qhov ntsuas kev ua tau zoo ua tau raws li cov qauv tsim, xws li cov fibers alkali-resistant, cov fibers kub-resistant, thiab cov fibers muaj zog, high-modulus. Qhov no yuav tsum tau xaiv cov khoom siv minerals ib leeg lossis lwm cov pob zeb basalt rau "doping hloov kho" ntawm cov khoom siv basalt ntshiab.
