Ucwaningo ngemicu ye-basalt kuzicelo zobunjiniyela bomphakathi

1.Izikhombisi-ndlela zohlelo lokusebenza

• Izinto zokuqinisa ukhonkolo

I-Fiber Concrete (BFRC): Isinqamuleli I-Basalt FiberI-s (6-24mm) ixubene nokhonkolo (inani lokuxuba 0.1% -0.5%), elingathuthukisa kakhulu ukumelana nokuqhekeka (ukunciphisa ububanzi bokuqhekeka ngo-30% -50%), ukumelana nomthelela (ukwandisa izikhathi ezingu-2-3), nokuqina (ukumelana nokuqhwala kwebhayisikili kukhuphuke ngo-40%).

Ukushintshwa kwezinsimbi zokuqinisa insimbi: Ezindaweni ezonakalisayo (isb. ezobunjiniyela basolwandle), imigoqo yokuqinisa i-basalt fiber (Amabha we-BFRP) ingafaka esikhundleni sokuqiniswa kwensimbi ukuze kugwenywe izinkinga zokugqwala. Ngokwesibonelo, ukusetshenziswa bfrp ukuqinisa ezinsikeni zebhuloho eliwela ulwandle e-Qingdao kulindeleke ukuthi kunwetshwe iminyaka yokuphila kwayo ibe ngaphezu kweminyaka eyi-100.

• Ukuqiniswa nokulungiswa kwesakhiwo

Indwangu ye-Fiber / Mesh Ukuqinisa: Indwangu ye-basalt fiber (amandla aqinile ≥2000MPa) inamathiselwe ebusweni bemishayo namakholomu, engakhuphula umthamo wokuthwala umthwalo ngo-20% -30%. Isibonelo, ngemva kokuba ibhuloho elidala e-Sichuan liqiniswe ngendwangu ye-BF, isilinganiso somthwalo siyathuthukiswa sisuka ku-Highway-II siye ku-Class I.

Ukuqiniswa kwe-Seismic: izinhlanganisela eziqiniswe yi-fiber (I-BFRP) amakholomu kakhonkolo asongiwe, angathuthukisa ukudumba namandla okusebenzisa amandla, futhi afanele izakhiwo ezisezindaweni ezithandwa ukuzamazama komhlaba.

• Izakhiwo ezintsha eziyinhlanganisela

Amaphaneli wesangweji le-basalt fiber-polymer: asetshenziselwa uphahla olungasindi nezindonga zokuhlukanisa, anamandla amakhulu kanye nokufakwa okushisayo (i-thermal conductivity ≤ 0.05 W/mK).

Izinto zokwakha zokuphrinta ze-3D: i-basalt fiber-Izinto zikasimende eziqinisiwe zingakwazi ukubona ukuphrinta kwesakhiwo esiyinkimbinkimbi futhi kunciphise imfucuza yokwakha.

2.Izinzuzo Zobuchwepheshe kanye Nedatha Eyinhloko

3.Inqubekelaphambili yocwaningo kanye nezimo ezijwayelekile

• Ucwaningo lwasekhaya

Inyuvesi yaseTsinghua: ithuthukise ukhonkolo oguquliwe we-basalt fiber-nano-silica ngokunyuka kwamandla okucindezela okungama-25% kanye nokunciphisa ukukwazi ukungena kwe-chloride ion ngama-60%.

Inyuvesi yase-Southeast: i-BF/epoxy resin laminate ehlongozwayo eqinisiwe yobuchwepheshe bensimbi obuqinisiwe, impilo yokukhathala enwetshwa izikhathi ezingaphezu kwezingu-3.

• Isicelo samazwe ngamazwe

E-Japan: Ngemva kokuzamazama komhlaba kwase-Hanshin, ibhilidi eliphakeme e-Osaka lamukela i-BF mesh eqinisiwe yodonga lokugunda, futhi ukusebenza kokuzamazama komhlaba kwaba ngcono ngo-40%.

EYurophu: Kwasetshenziswa ukhonkolo oqiniswe yi-BF emasangweni okulawula izikhukhula e-Venice, e-Italy, isikhathi sokuphila seminyaka engu-50 ngokumelene nokuguguleka kwamanzi olwandle.

• Amacala Obunjiniyela

I-China - Hong Kong-Zhuhai-Macao Bridge: I-basalt fiber impahla eyinhlanganisela isetshenziswa ongqimbeni anti-ukugqwala kwezinye izinsika, kwehlisa izindleko zokulungisa ngo-30%.

I-USA - I-San Francisco Bay Area Rapid Transit (BART): Indwangu ye-BF isetshenziswa ekuqinisweni komugqa womhubhe, futhi ukumelana nokuguquguquka kukhuphuka ngama-25%.

4.Izinselele kanye Neziqondiso Zesikhathi esizayo

• Izinkinga ezikhona

Ukusebenza okunganele kwesibopho esiphakathi kobuso: isixhumi esibonakalayo phakathi kwefayibha nokhonkolo/i-resin ijwayele ukuxetshulwa, ama-agent amasha ahlanganisayo (isb., izilungisi ze-silane) zidinga ukuthuthukiswa.

Ukuntuleka kwedatha yokusebenza yesikhathi eside: izici ezinyakazayo zokuqiniswa kwe-BF ngaphansi kwezinga lokushisa eliphezulu kanye nemvelo yomswakama ophezulu (iminyaka engaphezu kwengu-10 yedatha namanje ayiphelele).

Ukufana kwesistimu evamile: ukucaciswa komklamo wobunjiniyela bezinto ze-BF emazweni ahlukahlukene akukakasungulwa ngokugcwele (i-China ikhiphe i-GB/T 38143-2019, kodwa imininingwane yohlelo lokusebenza izocwengisiswa).

• Isiqondiso socwaningo lwesikhathi esizayo

Izinhlanganisela zefiber ezihlakaniphile: izinzwa ezishumekiwe ukuze kuzuzwe ukuqapha kwezempilo kwesakhiwo (isb., ubunzima, ukuzazi kahle).

Ubuchwepheshe bokulungiselela okuluhlaza: nciphisa izinga lokushisa lokuncibilika nokudweba (okwamanje lidinga i-1400-1500 ℃), futhi uthuthukise inqubo yekhabhoni ephansi.

I-multi-scale synergistic reinforcement: ukuhlanganisa ne-carbon fibre ne-steel fibre ukuze kwakhiwe izinhlanganisela ze-gradient.

5.Isifinyezo

Ukusetshenziswa kwe i-basalt fiber kwezobunjiniyela bomphakathi isuke elabhorethri yaya emsebenzini wobunjiniyela, futhi izici zayo ezingabizi kakhulu nezihambisana nemvelo zifanelana nesidingo sezakhiwo eziluhlaza ngaphansi komgomo “we-dual-carbon”. Ngokuzayo, kuyadingeka ukwephula ukusebenza kahle kwesixhumi esibonakalayo, ukuqinisekiswa kokuhlala isikhathi eside kanye nobunye ubuchwepheshe obubalulekile, futhi ngasikhathi sinye kugqugquzelwe ukuthuthukiswa kokucaciswa kokuklama kanye nama-synergies e-industrial chain, ukuze kusheshiswe ukusetshenziswa kwayo okukhulu kwingqalasizinda emikhulu, ubunjiniyela basolwandle, ukuzamazama komhlaba nokuvimbela izinhlekelele nezinye izimo.
