Los ntawm Cov Khoom Siv Raw mus rau Daim Ntawv Thov: Basalt Fiber
Cov fiber basaltcov khoom lag luam qhia meej meej qhov zoo dua li iav fiber hauv Cov Khoom Siv Sib XyawsNyob rau hauv cov ntaub ntawv ntawm chopped lev, roving, thiab unidirectional ntaub,basalt fiber qhia tau tias muaj kev tawg ntau dua thiab Young's modulus (kev ntsuas ntawm qhov tawv rau ib yam khoom) piv rau cov iav fiber.
Hauv kev tshawb fawb uas tau ua los ntawm Xibfwb Ignaas Verpoest ntawm Lub Tsev Haujlwm Saib Xyuas Cov Khoom Siv Sib Xyaws ntawm Luvin University hauv Belgium, kev tshawb fawb tau ua tiav rau Basalt fiber thiab E-iav fiber. Cov khoom siv ua ntej ib txoj kev tau npaj los ntawm kev muab cov iav thiab basalt nrog epoxy resin impregnation, qhwv lawv rau ntawm lub mandrel, thiab tom qab ntawd nias cov laminates kom txog thaum kho tag nrho. Cov qauv ntsuas 135 hli × 15 hli (5.3 nti × 0.6 nti) tau txiav thiab ntsuas lawv cov tuab. Cov qauv tom qab ntawd tau raug rau peb-taw tes khoov kev sim (ISO 178) thiab ILSS kev sim (ISO 14130) los ntsuas lub zog thiab kev tawv.
Verpoest tau tshaj tawm tias thaum txhua tus qauv muaj cov fiber ntau ntawm 40%, lub zog ntawm cov qauv basalt / epoxy yog 13.7% siab dua li ntawm cov qauv E-iav, thiab lawv qhov kev tawv yog 17.5% siab dua, txawm hais tias cov qauv basalt yog 3.6% hnyav dua li cov qauv E-iav.
Tsis tas li ntawd xwb, cov fiber basalt yog ib txwm tiv taus ultraviolet (UV) thiab lub zog siab electromagnetic hluav taws xob, tswj nws cov khoom ntawm qhov kub qis, thiab muaj kev tiv thaiv acid zoo dua. Basalt kuj tau tshaj tawm tias muaj qhov zoo dua hauv kev nyab xeeb ntawm cov neeg ua haujlwm thiab huab cua zoo. Vim tias basalt yog cov khoom ntawm volcanic kev ua ub no, cov txheej txheem fiberization yog tus phooj ywg ib puag ncig ntau dua li cov iav fiber. Tsis tas li ntawd, basalt yog 100% inert, txhais tau tias nws tsis muaj tshuaj lom nrog huab cua lossis dej, thiab tsis kub hnyiab thiab tawg-pov thawj.
Cov ntawv thov hauv kev tiv thaiv hluav taws thiab kev rwb thaiv tsev thermal
Basalt fiber ntaub Cov ntaub uas tiv taus hluav taws kub muaj qhov kub thiab txias siab, rwb thaiv cua sov zoo heev, tsis yaj lossis ntws, tsis muaj pa roj lom, thiab tsis ntsws. Nws yog cov khoom siv zoo heev rau cov khaub ncaws tua hluav taws, cov pam tua hluav taws, thiab cov ntaub thaiv hluav taws, nrog rau qhov kub thiab txias txog li 650∘C thiab cov pa oxygen txwv ntau dua 68, zoo dua li aramid thiab lwm cov organic fibers.
Cov ntawv thov hauv Infrastructure
Cov fiber basalt muaj lub zog tensile siab, tiv taus acid thiab alkali, thiab cov khoom siv tshuaj ruaj khov. Nws tuaj yeem hloov cov ntawv carbon fiber ib nrab rau kev kho, kho dua tshiab, thiab txhawb nqa cov khoom siv hauv paus. Nws kuj tseem tuaj yeem hloov cov polyester fiber, polypropylene fiber, thiab polyacrylonitrile fiber rau kev txhawb nqa cov pob zeb mortar thiab asphalt concrete, muab cov khoom tsis muaj zog thiab tawg tsis kam. Nws tuaj yeem siv dav hauv cov teb hauv paus xws li txoj kev loj, txoj kev khiav dav hlau, chaw nres nkoj thiab chaw nres nkoj, thiab kev tsim kho hydropower.
Cov ntawv thov hauv kev tiv thaiv ib puag ncig
Basalt fiber yog ib hom tshiab ntawm cov khoom siv ntsuab thiab ib puag ncig uas tuaj yeem siv rau hauv kev tiv thaiv ib puag ncig rau kev lim, kev nqus, thiab kev ntxuav cov xov xwm thiab cov pa phem. Tshwj xeeb tshaj yog nyob rau hauv kev lim dej kub siab, qhov kub thiab txias siv ntev ntawm basalt fiber yog 650∘C, zoo dua li cov ntaub ntawv lim dej ib txwm muaj, ua rau nws yog cov khoom siv zoo tshaj plaws rau cov khoom siv lim dej, cov ntaub ntawv lim dej, thiab cov ntaub ntawv kub siab.
Cov ntawv thov ntawm Basalt Fiber Reinforced Plastics
Cov ntaub ntawv sib xyaw ua ke txhawb nqa nrog basalt fiber siv tau rau hauv kev tiv thaiv lub tebchaws xws li cov cuab yeej tiv thaiv mos txwv, radomes, kev tiv thaiv cua sov ntawm lub qhov phom, thiab cov ntaub ntawv zais cia rau kev nqus thiab xa radar. Lawv kuj tseem siv tau rau hauv kev siv pej xeem xws li cov qauv tsheb thiab nkoj, cov kav dej uas tiv taus siab thiab tiv taus xeb, cov thooj voos kheej kheej, thiab cov laug cam luam tawm.
