BFRP muaj ntau qhov zoo ntawm kev ua tau zoo, tab sis nws txoj kev loj hlob tseem ntsib ntau yam teeb meem ntawm tus nqi, thev naus laus zis, daim ntawv thov, cov qauv thiab kev kawm txog kev ua lag luam. Kev lag luam yuav tsum txhawb nqa kev tshawb fawb thiab kev txhim kho txuj ci, txo cov nqi tsim khoom, tsim cov qauv tsim nyog, thiab txhim kho kev paub ntawm cov neeg siv BFRP los ntawm kev txhawb nqa kev ua lag luam los txhawb nws daim ntawv thov hauv ntau thaj chaw.

Raws li qhov kev thov rau cov khoom siv zoo rau ib puag ncig nce ntxiv, cov fibers basalt maj mam yeej kev saib xyuas hauv ntau qhov chaw vim lawv cov khoom siv lub cev thiab tshuaj lom neeg zoo heev. Txawm hais tias daim ntawv thov tau ua tiav hauv cov teb xws li kev tsim kho txoj kev thiab cov ntaub ntawv lim dej, tseem muaj ntau chav rau kev tshawb fawb yav tom ntej. Cov hauv qab no yog kev xav txog kev tshawb fawb ntawm cov khoom fiber basalt.

Raws li ib qho kev hloov kho inorganic, basalt fiber tau raug kawm dav dav thiab siv rau cov ntaub ntawv asphalt. Nws cov khoom tshwj xeeb tsis yog tsuas yog txhim kho qhov tsis zoo ntawm asphalt nws tus kheej tab sis kuj txhim kho kev ua haujlwm ntawm txoj kev ntawm asphalt concrete. Kev nkag siab tob txog cov txheej txheem ntawm kev ua haujlwm ntawm basalt fibers yog qhov tseem ceeb heev rau kev ua kom zoo dua ntawm kev tsim qauv thiab kev siv cov khoom sib xyaw asphalt.

Hauv cov txheej txheem ntev ntawm lub ntiaj teb, basalt, ua ib qho khoom siv tseem ceeb ntawm ntuj tsim, nws qhov keeb kwm tshwj xeeb thiab kev faib tawm dav dav ua rau nws yog cov khoom siv raw zoo tshaj plaws rau kev tsim cov fibers basalt ua tau zoo. Hauv tsab ntawv no, peb yuav tham txog cov yam ntxwv, cov qauv xaiv thiab cov txheej txheem kho ntawm basalt.

Ib txoj cai lij choj European kom tshem tawm cov se rau cov khoom lag luam basalt xa tuaj tau tshaj tawm thiab tau txais hnub no ntawm 2024 World Green Design Organization Annual Conference thiab Brussels Summit hauv Brussels, Belgium.

Basalt fiber reinforcement yog cov khoom siv raw basalt fiber thiab cov khoom siv organic resin matrix raws li qee qhov kev sib xyaw ua ke thiab ntxiv cov khoom pabcuam kom tsim nyog thiab tsim cov khoom siv sib xyaw ua ke tshiab, hauv kev tsim kho vaj tse muaj kev cia siab zoo rau kev siv.

Basalt fiber yog ib qho inorganic modifier ib txwm muaj, cov kws tshawb fawb pom tias cov modifier yuav raug ntxiv rau cov khoom siv asphalt, tsis yog tsuas yog tuaj yeem daws cov yam ntxwv tsis zoo ntawm asphalt, tab sis kuj txhim kho kev ua tau zoo ntawm txoj kev asphalt concrete. Nws tau pom tias cov fiber tuaj yeem txhim kho kev ua tau zoo ntawm asphalt sib xyaw, cov fibers hauv asphalt sib xyaw rau peb-dimensional dispersed theem xeev muaj, kev tsim ntawm kev ruaj khov ntawm qhov chaw mesh qauv txiav txim siab qhov zoo ntawm txoj kev ua tau zoo ntawm asphalt sib xyaw. Yog li ntawd, kev nkag siab txog lub luag haujlwm ntawm basalt fiber mechanism, rau kev kawm txog asphalt sib xyaw yog qhov tseem ceeb heev.

Hauv cov txheej txheem tsim cov fiber ntau basalt tas mus li, txhawm rau txhim kho qhov zoo ntawm cov fiber, yuav tsum sim kom tsis txhob hnav thiab tsim kua muag ntawm cov fiber hauv cov txheej txheem tsim khoom, tib lub sijhawm rau ntau daim ntawv thov xav tau cov fibers nrog cov khoom sib txawv ntawm qhov chaw, yog li hauv cov txheej txheem tsim khoom feem ntau yuav tsum tau coated nrog roj ntawm qhov chaw ntawm cov fiber, kev lag luam hu ua infiltration agent. Kev siv cov neeg sawv cev infiltrating ntawm ib sab tes tuaj yeem ua lub luag haujlwm tiv thaiv hauv lubrication kom tsis txhob muaj kev puas tsuaj rau qhov chaw ntawm cov fiber, qhov thib ob kuj tuaj yeem txhim kho kev sib cuam tshuam ntawm cov monofilaments fiber, los muab lub luag haujlwm hauv pawg, thiab qhov thib peb tuaj yeem tsim los ntawm cov qauv ntawm tus neeg sawv cev infiltrating nws tus kheej los txhim kho cov khoom nto ntawm cov fiber kom tau raws li qhov xav tau sib txawv ntawm daim ntawv thov.

Cov khoom siv kho tshuab ntawm cov fibers basalt (piv txwv li, lub zog tensile, modulus ntawm elasticity, tawg toughness, thiab lwm yam) yog cov cim qhia tseem ceeb rau lawv daim ntawv thov hauv composites thiab engineering. Kev hloov kho nto tsis yog tsuas yog txhim kho cov khoom sib txuas ntawm cov fibers thiab cov ntaub ntawv matrix tab sis kuj tseem yuav cuam tshuam rau cov khoom siv kho tshuab ntawm cov fibers lawv tus kheej. Cov teebmeem no sib txawv nyob ntawm lub tshuab ntawm txoj kev hloov kho thiab cov txheej txheem kho. Cov hauv qab no yog kev sib piv kev tshuaj xyuas ntawm qhov cuam tshuam ntawm ntau txoj kev hloov kho rau cov khoom siv kho tshuab ntawm cov fibers basalt.

Basalt fiber yog ib qho fiber inorganic ua tau zoo uas siv dav hauv kev tsim kho vaj tse, cov ntaub ntawv sib xyaw thiab kev tiv thaiv ib puag ncig vim nws cov khoom siv kho tshuab zoo heev, tshuaj lom neeg tsis kam thiab kub siab ruaj khov. Txawm li cas los xij, vim nws qhov chaw du thiab tsis muaj cov pab pawg ua haujlwm nquag, kev sib txuas ntawm cov khoom siv matrix tsis zoo. Los ntawm kev hloov kho qhov chaw, cov khoom sib txuas ntawm cov fiber basalt tuaj yeem txhim kho tau zoo, yog li txhim kho lawv daim ntawv thov hauv cov ntaub ntawv sib xyaw thiab kev tiv thaiv ib puag ncig.
