Tsvagiridzo yebasalt fibers mune civil engineering application
1.Main application mirayiridzo
- Concrete kusimbisa zvinhu
Fiber Concrete (BFRC): Short-cut Basalt Fibers (6-24mm) inosanganiswa mukongiri (kuvhenganisa chiyero 0.1% -0.5%), iyo inogona zvakanyanya kunatsiridza mutswe kuramba (kuderedza mutswe upamhi ne 30% -50%), kukanganisa kuramba (kuwedzera ne 2-3 nguva), uye kusimba (chando-thaw cycling resistance yakawedzera ne40%).
Kutsiviwa kwesimbi yekusimbisa: Munzvimbo dzinoparadza (semuenzaniso marine engineering), basalt fiber reinforcing bars (BFRP mbariro) inogona kutsiva simbi yekusimbisa kudzivirira matambudziko ekuora. Somuenzaniso, kushandisa bfrp kusimbiswa mumapiji ebhiriji rekuyambuka-gungwa muQingdao inotarisirwa kuwedzera hupenyu hwayo kusvika kumakore anopfuura zana.
- Kusimbisa kwemaitiro uye kugadzirisa
Fiber Mucheka / Mesh Reinforcement: Basalt fiber jira (tensile simba ≥2000MPa) inonamirwa pamusoro pematanda nemakoramu, ayo anogona kuwedzera mutoro wekutakura ne20% -30%. Semuenzaniso, mushure mekunge bhiriji rekare muSichuan rasimbiswa nejira reBF, kuyerwa kwemutoro kunokwidziridzwa kubva kuHighway-II kuenda kuKirasi I.
Kusimbisa seismic: fiber-reinforced composites (BFRP) akaputirwa kongiri mbiru, izvo zvinogona kusimudzira ductility uye simba rinopedza simba, uye akakodzera zvivako munzvimbo kudengenyeka kwenyika.
- Zvimiro zvitsva zvinosanganiswa
Basalt fiber-polymer sandwich panels: inoshandiswa kumatenga akareruka uye madziro ekuparadzanisa, ane simba rose uye kupisa kwemafuta (thermal conductivity ≤ 0.05 W/mK).
3D kudhinda zvinhu zvekuvaka: basalt fiber-yakasimbiswa cementitious zvinhu zvinogona kuona yakaoma chimiro kudhinda uye kuderedza marara ekuvaka.
2.Technical Advantages uye Core Data
| Performance Indicators | Basalt fiber | Kuenzanisa zvinhu (girazi fiber) |
| Kusimba simba | 3000-4800 MPa | 2000-3500 MPa |
| Alkali kuramba (pH=13) | Kuchengetedza simba ≥90% | Girazi faibha: kuchengetedza simba ≤ 50% |
| Mabhenefiti ezvakatipoteredza: kugadzirwa kwesimba rekushandisa ingori 30% yegirazi fiber, uye inogona kudzokororwa 100%. | ||
3.Research Progress uye Typical Cases
- Tsvakurudzo yemumba
Tsinghua University: yakagadzira basalt fiber-nano-silica composite yakagadziridzwa kongiri ine 25% compressive simba kuwedzera uye 60% chloride ion permeability kuderedza.
Yunivhesiti yeSoutheast: yakarongwa BF/epoxy resin laminate yakasimbisa yakasimbiswa kongiri tekinoroji tekinoroji, kuneta hupenyu hwakawedzerwa nekanopfuura ka3.
- International application
Japan: Mushure mekudengenyeka kwenyika kweHanshin, chivakwa chepamusoro-soro muOsaka chakagamuchira BF mesh yakasimbisa shear madziro, uye kuita kwekudengenyeka kwakavandudzwa ne40%.
Europe: BF yakasimbiswa kongiri yakashandiswa mumasuwo ekudzora mafashamo muVenice, Italy, nehupenyu hwemakore 50 pakurwisana nekukukurwa kwemvura yegungwa.
- Injiniya Nyaya
China - Hong Kong-Zhuhai-Macao Bridge: Basalt fiber composite zvinhu zvinoshandiswa mu-anti-corrosion layer yemamwe pier, ichidzikisa mutengo wekugadzirisa ne30%.
USA - San Francisco Bay Area Rapid Transit (BART): BF jira rinoshandiswa mukusimbisa tunnel lining, uye deformation kuramba inowedzerwa ne25%.
4.Matambudziko uye Remangwana Nhungamiro
- Matambudziko aripo
Kusakwana kwekubatana kwekubatana kwemaitiro: iyo interface pakati pefayibha nekongiri / resin inogara ichikurura, mitsva yekubatanidza maajenti (semuenzaniso, silane modifiers) inoda kuvandudzwa.
Kushaikwa kwedata rekuita kwenguva refu: zvinokambaira hunhu hweBF kusimbiswa pasi pekushisa kwepamusoro uye hunyoro hwakanyanya nharaunda (anopfuura makore gumi e data achiri asina kukwana).
Uniformity yeyakajairwa system: engineering dhizaini yezvigadzirwa zveBF munyika dzakasiyana haisati yanyatsogadziriswa (China yakaburitsa GB/T 38143-2019, asi ruzivo rwekushandisa runofanira kunatswa).
- Nhungamiro yekutsvakurudza yeramangwana
Intelligent fiber composites: yakadzamirirwa ma sensors kuti uwane hutano hwekutarisa hutano (semuenzaniso, kunetsa, kupaza kuzviziva).
Green kugadzirira tekinoroji: kuderedza kunyunguduka uye kudhirowa tembiricha (ikozvino inoda 1400-1500 ℃), uye gadzira yakaderera-kabhoni maitiro.
Multi-scale synergistic reinforcement: kusanganisa nekabhoni faibha uye simbi faibha kugadzira gradient macomposites.
5.Summary
Kushandiswa kwe basalt fiber muCivil engineering yatama kubva murabhoritari kuenda kuenjiniya maitiro, uye hunhu hwayo husingadhuri uye hune hushamwari hwezvakatipoteredza hunoenderana nekudiwa kwezvivakwa zvakasvibirira pasi pechinangwa che "dual-carbon". Mune ramangwana, zvinofanirwa kupaza kuburikidza neiyo interface optimization, yenguva refu durability verification uye mamwe akakosha matekinoroji, uye panguva imwechete kusimudzira kuvandudzwa kwemaitiro ekugadzira uye maindasitiri echeni synergies, kuitira kuti ikurumidze kushanda kwayo kwakakura muhukuru-hukuru, engineering yegungwa, kudengenyeka kwenyika uye kudzivirira njodzi uye zvimwe zviitiko.
