Cov fiber basalt uas raug txiav yog ib qho inorganic mineral fiber nrog qhov ntev tsawg dua 50 hli uas raug txiav los ntawm cov khoom siv basalt fiber sib xws thiab tuaj yeem sib xyaw ua ke hauv cov pob zeb ua vaj tse. Raws li nws siv, nws tuaj yeem faib ua cov pob zeb ua vaj tse. fiber uas tsis tawg (BF), cov fiber reinforcing fiber (BZ) thiab cov fiber mortar crack-resistant (BSF).
Cov pob zeb basalt fiber ntau uas raug txiav yog feem ntau yog ntxiv cov fibers basalt uas raug txiav tas mus li lossis tsis txuas ntxiv rau hauv cov pob zeb hauv qhov ntau thiab tsawg, thiab hauv txoj hauv kev tsim nyog, los txhim kho lub zog thiab lub zog tensile ntawm cov pob zeb, thaum khaws cia lub zog compressive qub ntawm cov qauv pob zeb. lub zog, yog li ntawd kom txhawb nqa cov pob zeb thiab ua kom lub neej ua haujlwm ntev dua.
Qhov tshwm sim ntawm cov fiber basalt txiav ua kom tiav qhov sib txawv ntawm cov ntaub ntawv thiab cov txheej txheem, thiab ua lub luag haujlwm tseem ceeb hauv kev txhawb nqa kev txhawb nqa thiab kev txhawb nqa ntawm cov pob zeb ua vaj tseNws lub luag haujlwm hauv kev txhawb nqa pob zeb thiab kev txhawb nqa yog pom tseeb hauv cov hauv qab no:
(1) Cov xov basalt txiav tuaj yeem siv tag nrho lawv qhov chaw thiab qhov ntau ntawm cov txiaj ntsig, yog li txwv tsis pub cov kab nrib pleb me me ua rau lawv tsis sib txuas, thiab cov txiaj ntsig zoo kawg nkaus. Tib lub sijhawm, nws kov yeej qhov tsis zoo ntawm lwm cov xov hluavtaws xws li qhov ceev qis, lub zog tensile qis thiab elastic modulus, xws li yooj yim rub tawm thaum cov kab nrib pleb nthuav dav, uas tuaj yeem tiv thaiv kev nthuav dav ntawm cov kab nrib pleb me me uas twb muaj lawm thiab cov tsos ntawm cov kab nrib pleb tshiab. Kev yaj thiab kev tsis nkag tau ua si ib qho txiaj ntsig.
(2) Ntxiv rau qhov zoo ib yam li cov hlau fiber, cov fiber basalt txiav tuaj yeem siv nws cov modulus siab thiab ib qho siab tensile zog kom tsis txhob nthuav dav ntawm cov kab nrib pleb, thiab nws kuj tseem tuaj yeem tiv thaiv cov hlau fibers kom yooj yim knotted thaum lub sijhawm do, uas tsis zoo rau lub twj tso kua mis. Kev xa khoom, cov txheej txheem tsim kho yog qhov nyuaj.
(3) Cov fiber basalt uas raug txiav yog cov nitrocellulose ib txwm muaj, uas muaj kev sib raug zoo ntuj, thiab vim tias nws zoo sib xws hauv qhov ceev rau cov cement concrete thiab mortar, qhov ceev yog ntawm 2.63-2.8g / m³; ua haujlwm tau zoo, cov fiber basalt uas raug txiav tuaj yeem faib sib npaug tom qab tau koom ua ke rau hauv cov qauv pob zeb.
(4) Qhov saum npoo ntawm cov fiber basalt txiav tau hloov kho, thiab nws yog ib hom "inert fiber", uas muaj kev tiv thaiv kub zoo heev, tiv thaiv corrosion thiab cuam tshuam. Nws tuaj yeem tswj tau qhov ruaj khov hauv qhov kub thiab txias thiab qhov chaw corrosive siab, thiab tuaj yeem txhim kho qhov tsis kam deformation ntawm cov cement matrix. Yog li ntawd, cov fiber basalt txiav tuaj yeem hloov kho rau qhov chaw ib puag ncig hnyav hauv txhua theem ntawm kev sib tov pob zeb, nchuav, coagulation thiab siv, thiab txhim kho qhov ruaj khov ntawm cov pob zeb.
