Kev Tshawb Fawb Txog Kev Siv Cov Fiber Basalt Uas Tau Muab Tso Rau Hauv Cov Pob Zeb Ua Vaj Tse
Ntxiv rau cov fiber basalt, cov roj carbon fiber, Iav Fibers, thiab cov fiber aramid kuj tau siv los ua cov khoom siv txhawb zog hauv cov pob zeb ua vaj tse. Txawm li cas los xij, kev xyaum mus sij hawm ntev tau qhia tias cov ntaub ntawv no muaj qee yam teeb meem thaum siv rau cov pob zeb ua vaj tse, ua rau nws nyuaj rau ua kom tau raws li kev xav tau ntawm kev ua lag luam rau cov pob zeb ua vaj tse ua tau zoo. Kev tshwm sim ntawm cov fiber basalt txiav tau ua tiav qhov sib txawv no hauv ob qho tib si cov ntaub ntawv thiab cov txheej txheem, txhawb nqa kev txhim kho ntawm cov pob zeb ua vaj tse txhawb nqa thiab cov thev naus laus zis txhawb nqa. Nws lub luag haujlwm hauv kev txhawb nqa cov pob zeb ua vaj tse feem ntau pom tseeb hauv cov hauv qab no:
1.Kev Tiv Thaiv Kev Nchuav Zoo: Cov fibers basalt txiav, siv lawv qhov ntau thiab qhov zoo ntawm thaj chaw, tuaj yeem tiv thaiv cov kab nrib pleb me me thiab tiv thaiv lawv txoj kev nthuav dav thiab kev sib txuas. Tib lub sijhawm, lawv kov yeej qhov tsis zoo ntawm lwm cov fibers hluavtaws, xws li qhov ceev qis, lub zog tensile qis, thiab cov qauv elastic qis. Lawv tsis yooj yim rub tawm thaum lub sijhawm tawg, cuam tshuam loj heev rau kev tsim cov kab nrib pleb me me thiab ncua kev tsim cov kab nrib pleb tshiab, uas cuam tshuam zoo rau kev tsis nkag mus ntawm cov pob zeb thiab kev tiv thaiv khov-thaw.
2.Modulus siab thiab Kev Tsim Kho Kev yooj yim: Cov fibers basalt txiav tsis yog tsuas yog muab cov txiaj ntsig ntawm cov modulus siab thiab lub zog tensile ib leeg, zoo ib yam li cov hlau fibers, los tiv thaiv kev tawg, tab sis lawv kuj kov yeej cov teeb meem ntawm cov hlau fibers, xws li lawv nyiam sib sau ua ke thaum sib tov, uas cuam tshuam kev twj thiab kev tsim kho.
3.Kev tawg zoo thiab kev sib raug zooUa ib hom fiber inorganic uas muaj silicate, cov fiber basalt no muaj qhov sib xws nrog cov khoom siv cement. Nws qhov ceev (kwv yees li 2.63-2.80 g/cm³) zoo ib yam li cov cement concrete thiab mortar, ua kom nws ua haujlwm tau zoo, thiab nws tuaj yeem tawg ua ke hauv cov qauv concrete tom qab sib xyaw ua ke.
4.Kev Ruaj Khov Zoo Kawg Nkaus: Hloov kho qhov chaw cov fiber basalt uas raug txiav ua tej daim me me qhia txog cov yam ntxwv ntawm "inert fiber", qhia txog kev tiv taus kub siab, tiv taus xeb, thiab tiv taus kev cuam tshuam. Lawv tswj tau qhov ruaj khov txawm tias nyob rau hauv qhov kub siab thiab qhov chaw xeb heev thiab tuaj yeem txhim kho qhov kev tiv taus deformation ntawm cov cementitious matrix. Yog li ntawd, lawv tuaj yeem hloov kho rau qhov chaw nyuaj ntawm kev sib tov pob zeb, nchuav, teeb tsa, thiab siv cov theem, ua rau cov pob zeb ruaj khov dua.
Hauv kev xaus, cov fiber basalt uas raug txiav Nws tuaj yeem ua kom cov pob zeb ua vaj tse tsis yooj yim tawg, txo nws qhov brittleness, thiab txhim kho nws cov khoom siv kho tshuab. Tshwj xeeb, nws tuaj yeem ua lub luag haujlwm hauv kev tiv thaiv kev tawg, kev tsis nkag, kev ruaj khov dua, kev cuam tshuam zoo dua thiab kev tiv thaiv tensile, thiab pab txhawb kom zoo nkauj dua hauv cov qauv pob zeb.
