Kev tshawb fawb txog basalt fibers hauv kev siv engineering engineering
1.Main daim ntawv qhia cov lus qhia
- Cov khoom siv ua vaj tse
Fiber Concrete (BFRC): luv luv Basalt Fiber ntaus (6-24mm) yog tov rau hauv pob zeb (sib tov ntau npaum li cas 0.1%-0.5%), uas tuaj yeem txhim kho kev ua kom tawg tau zoo (txo cov kab nrib pleb los ntawm 30% -50%), cuam tshuam tsis kam (nce 2-3 zaug), thiab durability (khov-thaw cycling resistance nce 40%).
Hloov cov hlau reinforcement: Nyob rau hauv corrosive ib puag ncig (xws li marine engineering), basalt fiber reinforcing tuav (BFRP tuav) tuaj yeem hloov kho steel kom tsis txhob muaj teeb meem corrosion. Piv txwv li, kev siv ntawm bfrp ua Kev txhawb nqa hauv cov piers ntawm tus choj hla hiav txwv hauv Qingdao xav tias yuav txuas ntxiv nws txoj sia mus rau ntau dua 100 xyoo.
- Kev tsim kho thiab kev txhim kho
Fiber Cloth / Mesh Reinforcement: Basalt fiber ntau daim ntaub (lub zog tensile ≥2000MPa) yog pasted rau saum npoo ntawm kab teeb thiab kab, uas tuaj yeem ua rau kom muaj peev xwm nqa tau 20% -30%. Piv txwv li, tom qab tus choj qub hauv Sichuan tau ntxiv dag zog nrog BF daim ntaub, qhov kev ntsuas kev thauj khoom tau hloov kho los ntawm Txoj Kev Loj-II mus rau Chav Kawm I.
Seismic reinforcement: fiber ntau-reinforced composites (BFRP) qhwv cov pob zeb ua ke, uas tuaj yeem txhim kho cov ductility thiab kev siv lub zog, thiab tsim nyog rau cov tsev nyob hauv thaj chaw av qeeg.
- Cov qauv sib xyaw tshiab
Basalt fiber-polymer sandwich panels: siv rau lub ru tsev sib sib zog nqus thiab muab faib phab ntsa, nrog rau ob qho tib si siab zog thiab thermal rwb thaiv tsev (thermal conductivity ≤ 0.05 W / mK).
3D printing tsev cov ntaub ntawv: basalt fiber ntau-cov khoom siv cementitious tuaj yeem paub cov qauv luam ntawv nyuaj thiab txo cov khoom siv pov tseg.
2.Technical Advantages thiab Core Data
| Performance Indicators | Basalt fiber ntau | Cov khoom sib piv (iav fiber ntau) |
| Tensile zog | 3000-4800 MPa | 2000-3500 MPa |
| Alkali tsis kam (pH = 13) | Kev tuav ruaj khov ≥90% | Cov iav fiber ntau: ruaj khov ≤ 50% |
| Ib puag ncig zoo: kev siv hluav taws xob ntau tsuas yog 30% ntawm iav fiber ntau, thiab tuaj yeem ua 100% rov ua dua. | ||
3. Kev Tshawb Fawb Kev Tshawb Fawb thiab cov xwm txheej zoo
- Kev tshawb fawb hauv tsev
Tsinghua University: tsim basalt fiber-nano-silica composite hloov ua vaj tse nrog 25% compressive zog nce thiab 60% chloride ion permeability txo.
Lub Tsev Kawm Ntawv Qib Siab Sab Hnub Tuaj: npaj siab BF / epoxy resin laminate reinforced pob zeb siv tshuab, qaug zog lub neej txuas ntxiv los ntawm ntau dua 3 zaug.
- Kev thov thoob ntiaj teb
Nyiv: Tom qab av qeeg Hanshin, ib lub tsev siab siab hauv Osaka tau txais BF mesh reinforced shear phab ntsa, thiab kev ua haujlwm seismic tau txhim kho los ntawm 40%.
Teb chaws Europe: BF reinforced pob zeb tau siv nyob rau hauv cov rooj vag tswj dej nyab hauv Venice, Ltalis, nrog lub neej ntev ntawm 50 xyoo tiv thaiv dej hiav txwv yaig.
- Engineering Cases
Tuam Tshoj - Hong Kong-Zhuhai-Macao Choj: Basalt fiber ntau Cov khoom siv sib xyaw yog siv rau hauv cov txheej txheem tiv thaiv corrosion ntawm qee qhov piers, txo tus nqi txij nkawm los ntawm 30%.
TEB CHAWS USA - San Francisco Bay Area Rapid Transit (BART): BF ntaub yog siv nyob rau hauv lub qhov hauv ob sab phlu, thiab deformation kuj yog nce los ntawm 25%.
4. Cov kev sib tw thiab cov kev taw qhia yav tom ntej
- Cov teeb meem uas twb muaj lawm
Kev sib txuas ntawm kev sib txuas tsis txaus: qhov kev sib txuas ntawm fiber ntau thiab pob zeb / cob yog feem ntau rau stripping, tshiab coupling agents (xws li, silane modifiers) yuav tsum tau tsim.
Tsis muaj cov ntaub ntawv kev ua tau zoo mus ntev: cov yam ntxwv ntawm BF kev txhawb nqa nyob rau hauv qhov kub thiab txias ib puag ncig (ntau tshaj 10 xyoo ntawm cov ntaub ntawv tseem tsis zoo).
Kev tsis sib xws ntawm cov txheej txheem: engineering tsim tshwj xeeb rau BF cov ntaub ntawv hauv ntau lub tebchaws tseem tsis tau tsim kom tiav (Tuam Tshoj tau tso tawm GB / T 38143-2019, tab sis cov ntaub ntawv thov yuav tsum tau ua kom zoo dua).
- Kev tshawb fawb yav tom ntej
Intelligent fiber composites: embedded sensors kom ua tiav kev saib xyuas kev noj qab haus huv (xws li, lim, tawg kev paub txog tus kheej).
Green npaj technology: txo qhov kub thiab txias (tam sim no xav tau 1400-1500 ℃), thiab tsim cov txheej txheem qis carbon.
Multi-scale synergistic reinforcement: blending nrog carbon fiber thiab steel fiber los tsim gradient composites.
5. Cov ntsiab lus
Daim ntawv thov ntawm basalt fiber ntau nyob rau hauv civil engineering tau tsiv tawm ntawm lub chaw soj nstuam mus rau engineering xyaum, thiab nws cov nqi-zoo thiab ib puag ncig tus phooj ywg tus cwj pwm haum rau qhov kev thov rau ntsuab vaj nyob rau hauv lub hom phiaj ntawm "dual-carbon". Yav tom ntej, nws yog ib qho tsim nyog yuav tsum tau tawg los ntawm kev ua kom zoo, nyob rau hauv tib lub sij hawm txhawb nqa cov kev txhim kho ntawm cov qauv tsim qauv, ua rau muaj kev tiv thaiv ntev, kev tiv thaiv av qeeg thiab lwm yam kev puas tsuaj loj thiab lwm yam kev puas tsuaj.
