Los ntawm Raw Khoom rau Daim Ntawv Thov: Basalt Fiber
Basalt fiber ntaucov khoom nthuav qhia meej qhov zoo dua iav fiber ntau hauv Cov khoom siv sib xyaw. Nyob rau hauv cov ntaub ntawv ntawm tws lev, roving, thiab unidirectional ntaub,basalt fiber ntau Ua kom pom kev tawg ntau dua thiab Young's modulus (ib qho kev ntsuas nruj rau cov khoom muab) piv rau iav fiber.
Hauv kev tshawb fawb los ntawm Xib Fwb Ignaas Verpoest ntawm Lub Tsev Haujlwm Saib Xyuas Cov Khoom Siv Khoom ntawm Luvin University hauv Belgium, kev tshawb fawb tau ua tiav ntawm Basalt fiber ntau thiab E-iav fiber ntau. Unidirectional prepregs tau npaj los ntawm impregnating ob lub iav thiab basalt nrog epoxy resin, winding lawv mus rau ib tug mandrel, thiab ces nias lub laminates kom txog thaum tag nrho curing tiav. Cov qauv ntsuas 135 mm × 15 mm (5.3 nti × 0.6 ntiv tes) raug txiav thiab lawv cov thickness ntsuas. Cov qauv no tau raug kuaj peb-point dabtsi yog khoov (ISO 178) thiab ILSS xeem (ISO 14130) txhawm rau ntsuas lub zog thiab nruj.
Verpoest tau tshaj tawm tias thaum txhua tus qauv muaj fiber ntau feem ntawm 40%, lub zog ntawm cov qauv basalt / epoxy yog 13.7% siab dua li cov qauv E-iav, thiab lawv qhov tawv nqaij yog 17.5% siab dua, txawm tias cov qauv basalt yog 3.6% hnyav dua li cov qauv E-iav.
Tsis tas li ntawd, basalt fiber ntau yog ib txwm tiv taus ultraviolet (UV) thiab hluav taws xob hluav taws xob hluav taws xob siab, tswj nws cov khoom ntawm qhov kub thiab txias, thiab muaj cov kua qaub zoo dua. Basalt kuj tau tshaj tawm tias muaj qhov zoo tshaj plaws ntawm cov neeg ua haujlwm kev nyab xeeb thiab huab cua zoo. Txij li thaum basalt yog ib yam khoom ntawm volcanic kev ua si, cov txheej txheem fiber ntau yog ib puag ncig zoo dua li cov iav fiber ntau. Tsis tas li ntawd, basalt yog 100% inert, txhais tau tias nws tsis muaj tshuaj lom nrog huab cua lossis dej, thiab tsis yog-combustible thiab tawg-pov thawj.
Daim ntawv thov hauv Kev Tiv Thaiv Hluav Taws Xob thiab Thermal Rwb thaiv tsev
Basalt fiber ntau woven rau hauv fireproof ntaub muaj kub kuj, zoo heev thermal rwb thaiv tsev, tsis melting los yog dripping, tsis muaj tshuaj lom emissions, thiab tsis thermal shrinkage. Nws yog ib qho khoom siv zoo heev rau cov hluav taws kub hnyiab, cov pam hluav taws, thiab cov ntaub thaiv hluav taws, nrog rau qhov kub thiab txias txog li 650∘C thiab qhov txwv tsis pub muaj cov pa oxygen ntau dua 68, zoo dua rau aramid thiab lwm cov organic fibers.
Kev siv hauv Infrastructure
Basalt fiber ntau muaj lub zog tensile siab, acid thiab alkali tsis kam, thiab cov khoom siv tshuaj ruaj khov. Nws tuaj yeem hloov pauv cov nplooj ntawv carbon fiber ntau rau kev kho, kho dua tshiab, thiab txhim kho cov txheej txheem. Nws tuaj yeem hloov pauv polyester fiber, polypropylene fiber ntau, thiab polyacrylonitrile fiber ntau rau kev txhawb nqa mortar pob zeb thiab asphalt pob zeb, uas muaj zog impermeability thiab tawg tsis kam. Nws tuaj yeem siv dav hauv kev tsim kho vaj tse xws li kev loj, tshav dav hlau khiav, seaports thiab wharves, thiab hydropower engineering kev tsim kho.
Daim ntawv thov hauv Environmental Protection
Basalt fiber yog ib yam tshiab ntawm ntsuab thiab ib puag ncig tus phooj ywg cov ntaub ntawv uas yuav siv tau nyob rau hauv kev tiv thaiv ib puag ncig rau kev pom, adsorption, thiab purification ntawm teeb meem tawm thiab gases. Tshwj xeeb tshaj yog nyob rau hauv high-temperature pom, lub sij hawm ntev siv kub ntawm basalt fiber ntau yog 650∘C, deb tshaj li cov khoom siv lim dej ib txwm siv, ua rau nws nyiam cov khoom siv lim dej, lim cov ntaub ntawv, thiab cov ntaub ntawv kub siab.
Daim ntawv thov ntawm Basalt Fiber Reinforced Plastics
Composite cov ntaub ntawv txhawb zog nrog basalt fiber ntau tuaj yeem siv rau hauv daim ntawv thov kev tiv thaiv hauv tebchaws xws li cov phom tsis muaj phom, radomes, phom phom thermal tiv thaiv, thiab cov ntaub ntawv stealth rau radar nqus thiab kis tau tus mob. Lawv kuj tuaj yeem siv rau hauv kev siv pej xeem xws li tsheb thiab nkoj cov qauv, cov kav dej siab-resistant thiab corrosion-resistant, lub tog raj kheej qhov txhab, thiab cov ntawv luam tawm.
