Kev Sawv ntawm Basalt Fiber
Cov fiber basalt, luv luv li CBF, yog cov fiber txuas ntxiv uas tsis yog hlau uas tsim los ntawm cov basalt ore los ntawm kev yaj thiab kos duab kub siab. Nws tsis tsuas yog muaj cov khoom siv kho tshuab zoo heev, xws li lub zog siab thiab modulus siab, tab sis kuj ua rau pom zoo Tshuaj lom neeg kev ruaj khov, kev tiv taus kub siab, thiab qhov zoo ntawm tus nqi. Raws li cov khoom siv tseem ceeb ntawm cov khoom siv kho tshuab thiab cov khoom siv ntsuab, basalt fiber tau koom nrog plaub lub teb chaws cov khoom siv fiber tseem ceeb rau kev txhim kho (nrog rau carbon fiber, aramid fiber, thiab ultra-high molecular weight polyethylene fiber).
Cov txheej txheem npaj ntawm basalt fiber muaj ntau theem tseem ceeb, suav nrog kev xaiv cov khoom siv, kev sib tsoo, kev yaj, thiab kev kos duab. Theem xaiv cov khoom siv yuav tsum muaj cov khoom siv raw ore txaus thiab cov ntsuas kev ua tau zoo raws li cov qauv; theem sib tsoo suav nrog cov khoom siv raw crushing, kev sib cais sib nqus, thiab kev sib xyaw ua ke; thaum lub sijhawm yaj, cov khoom siv yuav tsum tau preheated rau kwv yees li 900 ℃, thiab tom qab ntawd cua sov rau 1300–1400 ℃ hauv lub cub hluav taws xob; thaum kawg, cov yaj raug rub mus rau hauv cov fibers los ntawm cov txheej txheem kos duab, thiab tom qab ntawd qhwv rau hauv cov khoom cylindrical los ntawm cov khoom siv xws li tus neeg sawv cev sizing, lub bundler, lub fiber tensioner, thiab lub tshuab winding tsis siv neeg. Nws yog ib qho tsim nyog sau cia tias cov tshuaj lom neeg sib xyaw ntawm basalt ore muaj kev cuam tshuam txiav txim siab rau cov ntsuas kev ua tau zoo ntawm fiber. Cov ntsiab lus hlau ntau dhau yuav ua rau tsis zoo thermal permeability thiab tsis tiav yaj ntawm basalt yaj, yog li txo cov txiaj ntsig yaj. Ntxiv mus, cov yam ntuj tsim xws li kev hloov pauv hauv cov khoom siv basalt deposit thiab tsis sib xws sab hauv crystallization kuj tuaj yeem cuam tshuam rau qhov zoo ntawm fiber. Thaum lub sijhawm cua sov, cov hlau oxides denser sib sau ua ke hauv platinum-rhodium alloy perforator ntawm qab ntawm lub kiln, ua rau muaj teeb meem erosion. Tib lub sijhawm, basalt muaj qhov kub thiab txias ntawm cov fiber, nrog rau qhov kub thiab txias ntawm crystallization yeej sib xws nrog qhov kub thiab txias ntawm daim duab kos; qhov xwm txheej crystallization no cuam tshuam tsis zoo rau lub zog tensile ntawm cov fiber.
Basalt Fiber Qhov Kev Ua Tau Zoo Tshaj Plaws Sib Piv Nrog Lwm Cov Fibers
Cov fiber basalt, nrog nws cov khoom tshwj xeeb, tau tshwm sim los ua tus thawj coj hauv Sib dua, cov ntaub ntawv sib xyaw ua ke muaj zog heev. Nws tsis tsuas yog muaj lub zog tensile zoo heev thiab elastic modulus tab sis kuj muaj lub neej ua haujlwm ntev, cov yam ntxwv tsis muaj kuab paug, ntau qhov kub thiab txias, thiab kev nqus dej tsawg. Ntawm ntau cov ntaub ntawv fiber, basalt fiber sawv tawm vim nws tsuas yog siv cov khoom siv raw li ntuj, thiab nws cov txheej txheem tsim khoom yog tus phooj ywg ib puag ncig, tsis tas yuav ntxiv cov khoom ntxiv.
Tom ntej no, peb yuav tshawb nrhiav txog cov yam ntxwv ntawm cov qauv, qhov zoo ntawm kev ua tau zoo, thiab kev siv tau ntawm cov fiber basalt hauv ntau qhov chaw.
(1) Cov Txheej Txheem Hloov Kho Tus Neeg Sawv Cev Coupling
Kev hloov kho cov neeg sawv cev txuas yog siv dav los txhim kho kev sib cuam tshuam ntawm cov khoom sib xyaw, yog li ua kom lawv cov khoom siv kho tshuab, thermal, thiab hluav taws xob zoo dua. Cov txheej txheem no siv cov nyhuv "bridging" ntawm cov neeg sawv cev txuas los txuas cov khoom sib txawv, ua kom lawv sib xws.
(2) Kev Sib Xyaws Ua Ke Nano-Modification thiab Coupling Agent Modification Txheej Txheem
Cov khoom sib xyaw ua ke ntawm basalt fiber tuaj yeem ua kom zoo dua los ntawm kev sib xyaw ua ke ntawm nano-modification thiab coupling agent modification. Cov txheej txheem hloov kho ua ke no tuaj yeem siv cov khoom zoo heev ntawm basalt fiber thiab nthuav dav nws cov cheeb tsam siv.
Basalt fiber muaj peev xwm siv dav hauv ntau qhov chaw.
Piv txwv li, hauv kev lag luam tshuaj lom neeg, nws tuaj yeem siv ua cov khoom siv tiv taus xeb; hauv kev lag luam tsheb, nws tuaj yeem siv ua cov khoom siv tiv taus hnav thiab tiv taus kev sib txhuam, nrog rau thaj chaw uas tiv taus kev cuam tshuam qis; hauv kev tsim kho, basalt fiber tuaj yeem txhim kho lub zog thiab kev ruaj khov ntawm cov pob zeb thiab cov cement mortar. Ntxiv mus, basalt fiber kuj muaj kev tiv taus kub zoo heev, ua rau nws tsim nyog rau kev rwb thaiv tsev kub, tiv taus hluav taws, thiab tiv taus kub hauv kev lag luam tsheb. Tom ntej no, peb yuav tshawb nrhiav kom meej txog kev siv basalt fiber hauv cov teb ntawm cov ntaub ntawv tsim kho thiab kev tsim kho vaj tse. Hauv kev tsim kho, basalt fiber tuaj yeem siv los tsim cov ntaub ntawv pultruded lossis cov hlau txhawb nqa rau kev txhawb nqa pob zeb. Nws muaj zog dua thiab sib dua li hlau, thaum muaj kev tiv taus ntuj rau alkalis, xeb, thiab acids. Ntxiv mus, basalt fiber muaj tib lub coefficient ntawm thermal expansion li pob zeb, ua rau nws yooj yim txiav rau hauv qhov ntev tshwj xeeb, zoo tagnrho rau kev siv hauv kev tsim kho.
Ib yam li ntawd, cov fiber basalt ua lub luag haujlwm tseem ceeb hauv kev tsim txoj kev. Nws tuaj yeem siv ua cov khoom siv txhawb nqa rau asphalt concrete, ua kom zoo dua lub zog tensile, toughness, thiab tiv taus rutting deformation ntawm txoj kev.
Ntxiv mus, cov fiber basalt ua tau zoo heev hauv kev lag luam petrochemical. Nws tuaj yeem tiv taus kev yaig ntawm cov pa roj organic, muab cov khoom siv tshiab rau kev tsim roj thiab roj av. Piv txwv li, cov khoom tshiab thiab cov txheej txheem rau cov khoom siv fiber basalt uas sib dua, muaj zog thiab cov khoom sib xyaw tuaj yeem tsim rau kev thauj mus los ntawm cov roj thiab roj av, cov kua kub thiab txias, thiab cov khoom siv loj, nrog rau kev tsim cov kav dej hydrogen uas ntev thiab siab.
Xaus lus, basalt fiber, nrog nws cov yam ntxwv tshwj xeeb thiab muaj peev xwm siv dav, tab tom ua lub luag haujlwm tseem ceeb hauv ntau qhov chaw. Nrog rau kev nce qib ntawm thev naus laus zis, kev cia siab ntawm kev siv basalt fiber yuav dav dua.
