Bincike akan filayen basalt a aikace-aikacen injiniyan farar hula
1.Main aikace-aikace kwatance
- Kankare kayan ƙarfafawa
Fiber Concrete (BFRC): Short-cut Basalt Fibers (6-24mm) suna gauraye a cikin kankare (yawan adadin 0.1% -0.5%), wanda zai iya inganta juriya mai mahimmanci (rage girman nisa da 30% -50%), juriya mai tasiri (ƙara ta sau 2-3), da karko (daskare-narke juriya na hawan keke ya karu da 40%).
Sauya ƙarfin ƙarfafa ƙarfe: A cikin mahalli masu lalacewa (misali injiniyan ruwa), sanduna ƙarfafa fiber na basalt (BFRP sanduna) zai iya maye gurbin ƙarfafa ƙarfin ƙarfe don kauce wa matsalolin lalata. Alal misali, amfani da bfrp Ana sa ran za a tsawaita tsawon rayuwarta zuwa fiye da shekaru 100 na gadar da ke kan tekun Qingdao.
- Ƙarfafawar tsari da gyarawa
Fiber Cloth/Mesh Reinforcement: Basalt fiber zane (ƙarfin ƙarfi ≥2000MPa) an manna a saman katako da ginshiƙai, wanda zai iya ƙara ƙarfin ɗaukar nauyi da 20% -30%. Alal misali, bayan da aka ƙarfafa tsohuwar gada a Sichuan da zanen BF, an haɓaka ƙimar lodi daga Babbar Hanya-II zuwa Class I.
Ƙarfafawar Seismic: Abubuwan da aka ƙarfafa fiber (Farashin BFRP) ginshiƙan da aka nannade, waɗanda za su iya haɓaka ductility da ƙarfin amfani da makamashi, kuma sun dace da gine-gine a wuraren da girgizar ƙasa ke da alaƙa.
- Sabbin tsarin haɗin kai
Basalt fiber-polymer sandwich panels: ana amfani da su don rufin rufin nauyi da bangon bangare, tare da duka ƙarfin ƙarfi da rufin thermal (ƙaddamarwar thermal ≤ 0.05 W / mK).
Kayan gini na bugu na 3D: basalt fiber-inarfafa kayan siminti na iya gane hadadden tsarin bugu da rage sharar gini.
2.Fa'idodin Fasaha da Bayanan Bayanai
| Manufofin Ayyuka | Basalt fiber | Kayan kwatance (fiber gilashi) |
| Ƙarfin ƙarfi | 3000-4800 MPa | 2000-3500 MPa |
| Juriya na Alkali (pH=13) | Riƙe ƙarfi ≥90% | Gilashin fiber: ƙarfin riƙewa ≤ 50% |
| Fa'idodin muhalli: samar da makamashin da ake amfani da shi shine kawai 30% na fiber gilashi, kuma ana iya sake yin fa'ida 100%. | ||
3.Bincike Ci gaba da Yawan Alkawura
- Binciken cikin gida
Jami'ar Tsinghua: ɓullo da basalt fiber-nano-silica composite modified kankare tare da 25% ƙarfin matsa lamba da 60% chloride ion rage permeability.
Jami'ar Kudu maso Gabas: BF/epoxy resin laminate da aka ba da shawarar ƙarfafa fasahar katako mai ƙarfi, rayuwar gajiya ta tsawaita fiye da sau 3.
- Aikace-aikacen ƙasa da ƙasa
Japan: Bayan girgizar kasa ta Hanshin, wani babban gini a Osaka ya karɓi ragamar BF ya ƙarfafa bango mai ƙarfi, kuma aikin girgizar ƙasa ya inganta da kashi 40%.
Turai: An yi amfani da simintin ƙarfafa BF a ƙofofin kula da ambaliya a Venice, Italiya, tare da tsawon rayuwa na shekaru 50 akan zaizayar ruwa.
- Abubuwan Injiniya
China - Gadar Hong Kong-Zhuhai-Macao: Basalt fiber Ana amfani da kayan haɗin gwiwa a cikin Layer anti-corrosion Layer na wasu piers, yana rage farashin kulawa da 30%.
Amurka - San Francisco Bay Area Rapid Transit (BART): Ana amfani da masana'anta BF a cikin ƙarfafa rufin rami, kuma juriya na lalacewa yana ƙaruwa da 25%.
4. Kalubale da Hanyoyi na gaba
- Matsalolin da suka wanzu
Rashin isassun ayyukan haɗin kai: mahaɗa tsakanin fiber da kankare / guduro yana da saurin cirewa, ana buƙatar haɓaka sabbin abubuwan haɗin gwiwa (misali, masu gyara silane).
Rashin bayanan aiki na dogon lokaci: halaye masu ban tsoro na ƙarfafa BF a ƙarƙashin yanayin zafi da zafi mai zafi (fiye da shekaru 10 na bayanai har yanzu basu cika ba).
Daidaita daidaitaccen tsarin: ƙayyadaddun ƙirar injiniya don kayan BF a cikin ƙasashe daban-daban ba a riga an kafa su ba (China ta fito da GB/T 38143-2019, amma za a tace bayanan aikace-aikacen).
- Jagoran bincike na gaba
Haɗin fiber na hankali: na'urori masu auna firikwensin don cimma nasarar sa ido kan lafiyar tsarin (misali, damuwa, faɗakar da kai).
Green shirye-shirye fasahar: rage narkewa da kuma zane zafin jiki (a halin yanzu bukatar 1400-1500 ℃), da kuma inganta low-carbon tsari.
Ƙarfafa haɗin kai na ma'auni mai yawa: haɗawa tare da fiber carbon da fiber fiber don gina abubuwan haɗin kai.
5.Taƙaice
Aikace-aikace na basalt fiber a cikin aikin injiniya na farar hula ya tashi daga dakin gwaje-gwaje zuwa aikin injiniya, kuma halayensa masu tsada da halayen muhalli sun dace da bukatun gine-ginen kore a karkashin manufar "dual-carbon". A nan gaba, ya zama dole a karya ta hanyar ingantawa da ke dubawa, tabbatar da dorewa na dogon lokaci da sauran fasahohi masu mahimmanci, kuma a lokaci guda inganta haɓaka ƙayyadaddun ƙira da haɗin gwiwar masana'antu, don haɓaka aikace-aikacensa mai girma a cikin manyan abubuwan more rayuwa, injiniyan ruwa, girgizar ƙasa da rigakafin bala'i da sauran al'amura.
