Kev Tshawb Fawb Txog Basalt Fiber Cov Kev Xav Tau Rau Daim Ntawv Thov
Txhim Kho Cov Qauv Pob Zeb
Piv txwv li, thaum txiav cov fiber basaltYog sib xyaw ua ke rau hauv cov cement matrix, lawv tsim ib lub cev "micro-skeleton" uas sib xws, peb-seem uas tuaj yeem tiv taus kev ntxhov siab ntawm kev hloov pauv shrinkage. Qhov no ua rau cov khoom siv ruaj khov dua, txhim kho kev ua haujlwm ntawm cov khoom, thiab tiv thaiv kev tawg, ua rau nws yog cov khoom siv txhawb nqa uas pheej yig heev. Basalt Fiber ua kom cov pob zeb ua tau zoo dua hauv peb txoj hauv kev no:
- Lub Zog Nce Siab: Cov pob zeb basalt fiber-reinforced qhia txog qhov kwv yees li 2.6% nce ntxiv hauv lub zog compressive, uas pab txhim kho qhov kev tiv thaiv khov-yaj ntawm cov pob zeb ua vaj tse.
- Txhim Kho Lub Zog Tensile thiab Flexural, thiab Ductility: Lub zog tensile sib cais ntawm basalt fiber-reinforced concrete nce ntxiv los ntawm kwv yees li 9.8%, nws lub zog flexural los ntawm kwv yees li 15.3%, thiab nws qhov kawg flexural tensile ntev los ntawm kwv yees li 19.1%Cov kev txhim kho no ncua qhov kev tsim cov kab nrib pleb thawj zaug thiab txo cov kab nrib pleb me me uas tshwm sim los ntawm kev ntsws ntawm cov pob zeb.
- Kev Tiv Thaiv Kev Xeb thiab Kev Ruaj Khov: Cov hlau basalt fiber-reinforced rebars tuaj yeem hloov cov hlau tau zoo, daws cov teeb meem engineering xws li xeb hlau thiab kev saib xyuas. Qhov no ua rau cov qauv concrete ruaj khov thiab muaj kev nyab xeeb dua.
Cov ntawv thov hauv Txoj Kev Asphalt Overlays
Hauv cov ntsiab lus ntawm txoj kev asphalt overlays, kev siv cov basalt fiber filaments anchored tuaj yeem tiv thaiv kev tawg transverse hauv txoj kev. Thaum basalt fiber filaments raug muab tso rau hauv txheej sab saud ntawm txoj kev, lawv tuaj yeem tiv thaiv kev tawg transverse ntawm qhov chaw. Yog tias muab tso rau hauv txheej qis dua, lawv tuaj yeem tiv thaiv kev tsim cov kab nrib pleb los ntawm cov txheej semi-rigid.
Kev nthuav dav ntawm Cov Ntawv Thov Kev Tsim Kho Vaj Tse
Hauv kev siv cov ntaub ntawv tsim kho vaj tse, cov fibers basalt txiav thiab cov khoom sib xyaw ua ke uas muaj fiber ntau (xws li rebars / connectors, cables, grids, thiab profiles) tau nce ntxiv thiab siv ua cov ntaub ntawv tsim kho thiab cov ntaub ntawv ua haujlwm (xws li cov vaj huam sib luag cua sov hauv pem teb thiab cov vaj huam sib luag nqus suab). Lawv siv tam sim no dhau ntawm cov carbon fiber nyob rau hauv thaj chaw no.
Lwm Cov Kev Siv Ua Haujlwm
Tsis tas li ntawd xwb, basalt fibertus coefficient nqus suab siab thiab qhov kub ua haujlwm siab tau ua rau nws siv rau hauv kev tsim cov khoom siv kho cua sov, fcov khoom siv rwb thaiv tsev uas tsis kub hnyiab, thiab cov khoom siv txo suab nrov.
