Kev Txhawb Nqa Basalt Fiber Hauv Kev Siv Engineering Thiab Kev Tshawb Fawb
1.Basalt Fiber kev txhawb zog hauv cov kev taug kev ua los ntawm cov pob zeb
Cov kev taug kev uas siv cov pob zeb ua kom ruaj khov tas mus li tswj tau qhov tawg vim yog qhov ntsws los ntawm kev muab cov pas nrig txhawb nqa txaus rau hauv qhov kev taw qhia ntev. Qhov kev tsim no tsis yog tsuas yog ua kom muaj peev xwm thauj khoom thiab ua kom ruaj khov ntawm txoj kev loj xwb tab sis kuj txhim kho qhov chaw tsav tsheb rau cov tsheb los ntawm kev tsis muab cov pob qij txha nthuav dav thiab sib cog lus thaum lub sijhawm. Kev Tsim KhoTxawm li cas los xij, vim tias txoj kev taug kev tsis tuaj yeem kaw tag nrho, tej yam xws li dej nag nkag thiab te tuaj yeem ua rau xeb ntawm cov hlau reinforcement, uas cuam tshuam loj heev rau lub neej kev pabcuam ntawm txoj kev loj.
Cov fiber basalt Cov khoom siv txhawb nqa tuaj yeem siv hloov cov hlau txhawb nqa ib txwm muaj rau cov kev taug kev uas txuas ntxiv txhawb nqa vim nws tiv taus xeb zoo heev thiab muaj zog tensile siab. Lwm txoj kev daws teeb meem no daws tau qhov teeb meem ntawm kev xeb hlau, yog li txhim kho qhov ruaj khov ntawm txoj kev taug kev ua los ntawm pob zeb. Tsis tas li ntawd, basalt fiber Kev txhawb zog yog cov khoom siv uas tsis muaj carbon thiab tsis ua rau ib puag ncig puas tsuaj, thiab nws qhov zoo dua tus nqi yuav nce ntxiv nrog rau kev siv cov hlau tsis muaj zog. Cov kev tshawb fawb uas twb muaj lawm tau qhia tias kev siv BF-RP txhawb zog hauv cov kev taug kev ua los ntawm cov pob zeb qhia tau tias muaj txiaj ntsig zoo hauv kev ruaj khov thiab kev tiv thaiv corrosion, thiab qhov nyuaj ntawm kev tsim kho thiab kev nce qib zoo ib yam li kev txhawb zog hlau. Txawm li cas los xij, vim yog qhov modulus ntawm elasticity ntawm BF-RP txhawb zog qis, nws yog qhov tsim nyog los nce nws qhov piv txhawb zog me ntsis, feem ntau ntawm 0.78% thiab 1.0%, thiab txais yuav lub tswv yim tsim ntawm "kev txhawb zog me me thiab qhov sib nrug ze".
2.Kev tshawb fawb txog kev txhawb nqa fiber basalt hauv kev txhawb nqa cov kem compression eccentric luv luv
Cov txheej txheem txhawb nqa ib txwm muaj feem ntau siv cov hlau sab nraud, tab sis txoj kev no nyuaj rau kev tsim kho thiab tsis muaj zog tiv taus qhov kub thiab txias. Cov khoom siv basalt fiber uas tsis hnyav, muaj zog, kub thiab tiv taus corrosion coj kev xaiv tshiab rau cov txheej txheem txhawb nqa. Tam sim no, cov thev naus laus zis txhawb nqa ntawm kev sib txuas basalt fiber cov ntawv yog laus lawm, tab sis kev tshawb fawb txog kev txhim kho lub peev xwm thauj khoom ntawm cov kem pob zeb los ntawm kev muab cov basalt fiber tendons tso rau hauv yog qhov me me. Cov ntaub ntawv cuam tshuam qhia tau tias basalt fiber kev txhawb nqa zoo heev txhim kho lub peev xwm khoov sab nraud ntawm cov kem pob zeb thiab tuaj yeem txhim kho lub peev xwm nqa khoom ntxiv los ntawm kev sib txuas cov txheej txheem ntawm kev xa tawm cov ntaub fiber basalt.
Cov txheej txheem tsim kho ntawm cov fiber basalt fiber ntxiv yog raws li nram no:
- Qhib lub qhov raws li qhov loj me ntawm tus qauv tsim
- Ntxuav lub qhov
- Siv cov tshuaj nplaum (epoxy resin adhesive)
- Kev muab cov kab BF-RP tso rau hauv
- Sau nrog cov ntawv binder kom sib npaug
- Tos kom cov nplaum khov thiab tom qab ntawd ua kev kho qhov chaw.
Los ntawm kev sib koom ua ke nrog cov ntaub basalt fiber sab nraud, qhov kev txhawb nqa BF-RP tuaj yeem zam qhov tshwm sim ntawm kev plam thiab spalling hauv cov txheej txheem ntawm kev ntxhov siab, kev tsim kho yooj yim thiab ua haujlwm tau zoo, thiab siv qhov chaw tsawg dua, uas muaj cov txiaj ntsig tsis muaj qhov sib piv.
3. Cov pob zeb ua los ntawm cov fiber basalt fiber
Cov khoom siv txhawb nqa BF-RP yog cov khoom siv txhawb nqa uas tsis yog hlau uas zoo rau ib puag ncig, muaj zog heev uas muaj cov yam ntxwv xws li kev tiv thaiv corrosion, electromagnetic rwb thaiv tsev, thiab kev tiv thaiv qaug zog, ua rau nws yog lwm txoj hauv kev zoo dua rau kev txhawb nqa hlau hauv qee qhov haujlwm tshwj xeeb. Txawm li cas los xij, tsis zoo li cov hlau ib txwm muaj, cov hlau BF-RP tsis muaj qhov taw qhia tseem ceeb thiab muaj qhov modulus qis ntawm elasticity, uas yuav ua rau muaj kev cuam tshuam ntau dua ntawm cov nqaj hlau uas raug rau tib lub nra hnyav. Txawm hais tias kev puas tsuaj ntawm cov pob zeb nrog BF-RP kev txhawb nqa yog brittle thiab tsis muaj kev kwv yees pom tseeb, nws tsim cov deformation loj ua ntej kev puas tsuaj, uas hloov chaw muab lus ceeb toom rau kev nyab xeeb ntawm cov qauv.
Yog tias lub tsev muaj cov kev cai nruj dua rau kev tawg pob zeb, nws yog ib qho tsim nyog los xav txog kev siv prestressing rau cov basalt fiber tendons, lossis nce lawv cov modulus ntawm elasticity, thiab sib xyaw thiab phim lawv nrog cov hlau reinforcement kom ntseeg tau tias lub tsev ruaj khov thiab muaj kev nyab xeeb.
