Tasirin Kayayyakin Ƙarfafa Fiber na Basalt akan Ayyukan Gine-gine na Seismic
1. Ingantattun Ƙarfi da Ƙarfi
Ƙarfin Ƙarfin Ƙarfin Ƙarfin Ƙarfin Ƙarfin Ƙarfin Ƙarfin Ƙarfin Ƙarfin Ƙarfin Ƙarfin Ƙarfi na basalt fibers iya isa 3000-4800 MPa, muhimmanci mafi girma fiye da na talakawa karfe (kimanin 400-600 MPa). Wannan yana ƙara haɓaka ƙarfi da ƙarfi na kayan karyewa kamar siminti da masonry, yana rage haɗarin fashewa ƙarƙashin nauyin girgizar ƙasa.
Modulus na roba Matsakaici: Matsakaicin na roba na basalt fibers (80-110 GPa) ya ta'allaka ne tsakanin na karfe (200 GPa) da carbon fiber (200-400 GPa). Wannan yana ba da ingantacciyar taurin kai ba tare da haifar da gazawa ba saboda tsauri da yawa.
2. Ingantattun Ƙwararren Ƙwararru
Ingantacciyar Ƙarfafawa: Tsarin kankare na gargajiya ba su da ƙarancin ductility kuma suna da saurin gazawa yayin girgizar ƙasa. Basalt Fibers, a matsayin ƙarfafawa, na iya tarwatsa tsatsauran ra'ayi da jinkirta yaɗuwar su, yana ba da damar sifofi su fuskanci nakasu kafin gazawar kuma su sami ƙarin ƙarfin girgizar ƙasa.
Ƙarfafa haɗin gwiwar Seismic: Ruɗewa ko haɗawa bfrp a wurare masu mahimmanci irin su katako-ginshiƙan katako da ganuwar shinge na iya haɓaka ƙarfin ƙarfi da iyawar lalacewa, hana gazawar saboda ƙaddamar da damuwa.
3. Ƙara Ƙarfin Ƙarfafa Ƙarfafa Ƙarfafawa
Ragewar Makamashi: Lokacin loading, Farashin BFRP kayan suna ɓatar da kuzari ta hanyar jujjuyawar fuska tsakanin zaruruwa da matrix, da nakasar fiber, yana rage ɓarnar tasirin makamashin girgizar ƙasa akan sifofi.
Halayen Damping: Basalt fiber abubuwan da aka haɗe suna da ƙayyadaddun rabo na damping, wanda zai iya rage girman girgizawar tsarin da kuma rage tasirin rawa.
4. Rage Nauyin Tsari
Kayayyakin Masu Sauƙaƙe: Basalt fibers suna da ƙarancin ƙima (kimanin 2.6-2.8 g/cm³), kashi ɗaya bisa uku na ƙarfe kawai. Sauya wani ɓangare na ƙarfafa ƙarfe tare da Farashin BFRP ko yin amfani da shi azaman kayan ƙarfafawa na iya rage nauyin gine-gine, rage ƙarfin girgizar ƙasa. Wannan yana da fa'ida musamman ga manyan gine-gine ko kuma sake fasalin tsoffin gine-gine.
5. Juriya na Lalata da Dorewa
Babban Juriya na Lalata: Basalt fibers suna da juriya ga acid, alkalis, yanayin zafi mai yawa, da danshi, yana sa su dace da yanayin lalata kamar yankunan bakin teku da tsire-tsire masu sinadarai. Tsawon aikinsu na dogon lokaci yana hana lalata aikin girgizar ƙasa saboda lalata kayan aiki.
Ƙananan Kuɗin Kulawa: Idan aka kwatanta da ƙarfafa ƙarfe na gargajiya, BFRP baya buƙatar kulawa da lalacewa akai-akai, yana haifar da ƙananan farashin rayuwa.
6. Forms Application and Scenarios
Ƙarfafa Ƙarfafawa: Ƙara yankakken zaruruwan basalt (misali, BFRC) zuwa kankare ko amfani da sandunan BFRP don maye gurbin ƙarfafa ƙarfe.
Ƙarfafa Ƙarfafawa: Ƙarfafa zanen gadon BFRP ko faranti don ƙarfafa katako, ginshiƙai, bango, da sauran abubuwan haɗin gwiwa, inganta wuraren raunin girgizar ƙasa.
Haɗin Haɓakawa: Haɗa BFRP tare da ƙarfe ko kankare don samar da tsarin tsarin matasan, daidaita ƙarfi da ductility.
7. Iyakance
Mafi Girma: A halin yanzu, farashin samarwa na Farashin BFRP ya fi na ƙarfe na yau da kullun amma ƙasa da carbon fiber (CFRP).
Ƙayyadaddun Bayanan Ayyuka na Tsawon Lokaci: Ana buƙatar ƙarin bincike game da dorewa da aikin gajiya na BFRP a tsawon lokaci mai tsawo (sama da shekaru 50).
Lambobin ƙira da ba su cika ba: Wasu ƙasashe har yanzu ba su gama shigar da BFRP gabaɗaya cikin lambobin ƙira na girgizar ƙasa ba, dogaro da gwaje-gwaje da ƙwarewar injiniya.
Abubuwan Injiniya da Bincike
Sake Girgizar Kasa ta Bayan Hanshin a Japan: Farashin BFRP an yi amfani da shi don sake gyara gadoji da gine-gine, yana nuna tasiri mai mahimmanci.
Sake Gina Girgizar Kasa Bayan Wenchuan a China: An sake gyara wasu makarantu da asibitoci da BFRP don inganta juriyar girgizar kasa.
Binciken Gwaji: Nazarin ya nuna cewa ginshiƙan da aka ƙarfafa BFRP na iya samun haɓakar 30% -50% a cikin ductility na ƙaura da haɓaka 20%-40% a cikin ƙarfin watsawar makamashi.
Kammalawa
Basalt fiber kayan da aka ƙarfafa suna haɓaka aikin girgizar ƙasa na gine-gine ta hanyar haɓaka ƙarfi, ductility, da ƙarfin tarwatsa makamashi. Sun dace musamman don manyan yankuna masu ƙarfi-seismic, gurɓatattun mahalli, ko yanayin yanayi masu buƙatar ƙira mara nauyi. Tare da raguwar farashi da haɓaka lambobin ƙira, aikace-aikacen BFRP a cikin injiniyan girgizar ƙasa yana da fa'ida mai fa'ida.
