Ucwaningo ngemicu ye-basalt kuzinhlelo zokusebenza zobunjiniyela bomphakathi

1. Izikhombisi-ndlela zohlelo lokusebenza oluyinhloko

• Izinto zokuqinisa ukhonkolo

I-Fiber Concrete (BFRC): I-Short-cut I-Basalt FiberAma-s (6-24mm) axutshwa kukhonkrithi (inani lokuxuba lingu-0.1%-0.5%), okungathuthukisa kakhulu ukumelana nokuqhekeka (ukunciphisa ububanzi bokuqhekeka ngo-30%-50%), ukumelana nokushayisana (ukwanda ngezikhathi ezingu-2-3), kanye nokuqina (ukumelana nokujikeleza kokuqandisa nokuncibilika kukhuphuke ngo-40%).

Ukufakwa esikhundleni kokuqinisa insimbi: Ezindaweni ezigqwalisayo (isb. ubunjiniyela basolwandle), imigoqo yokuqinisa i-basalt fiber (Amabha e-BFRP) ingathatha indawo yokuqinisa insimbi ukuze igweme izinkinga zokugqwala. Isibonelo, ukusetshenziswa i-bfrp Ukuqinisa izinsika zebhuloho eliwela ulwandle eQingdao kulindeleke ukuthi kwandise isikhathi sokuphila kwalo sibe ngaphezu kweminyaka eyi-100.

• Ukuqinisa nokulungisa isakhiwo

Ukuqinisa Indwangu Yefayibha/I-Mesh: Indwangu yefayibha ye-basalt (amandla okudonsa ≥2000MPa) inamatheliswa ebusweni bemishayo namakholomu, okungandisa amandla okuthwala umthwalo ngo-20%-30%. Isibonelo, ngemva kokuba ibhuloho elidala eSichuan liqiniswe ngendwangu ye-BF, isilinganiso somthwalo siyathuthukiswa kusukela ku-Highway-II kuya ku-Class I.

Ukuqinisa ukuzamazama komhlaba: izinhlanganisela eziqiniswe ngefayibha (I-BFRP) izinsika zekhonkrithi ezigoqiwe, ezingathuthukisa ukuguquguquka kanye namandla okusebenzisa amandla, futhi zifanele izakhiwo ezisezindaweni ezivame ukuzamazama komhlaba.

• Izakhiwo ezintsha ezihlanganisiwe

Amaphaneli esandwich e-basalt fiber-polymer: asetshenziselwa uphahla olulula kanye nezindonga zokuhlukanisa, anamandla aphezulu kanye nokushisa (ukushisa okuphezulu ≤ 0.05 W/mK).

Izinto zokwakha zokunyathelisa ze-3D: i-basalt fiberIzinto zokwakha eziqinisiwe zingenza ukuphrinta kwesakhiwo esiyinkimbinkimbi futhi zinciphise imfucuza yokwakha.

2. Izinzuzo Zobuchwepheshe kanye Nedatha Eyinhloko

3. Inqubekela phambili Yocwaningo kanye Namacala Ajwayelekile

• Ucwaningo lwasekhaya

IYunivesithi yaseTsinghua: yathuthukisa ikhonkrithi eguquliwe ye-basalt fiber-nano-silica ehlanganisiwe enokwenyuka kwamandla okucindezela angu-25% kanye nokunciphisa ukumuncwa kwe-chloride ion engu-60%.

I-Southeast University: ubuchwepheshe be-BF/epoxy resin laminate eqinisiwe eqinisiwe bekhonkrithi, isikhathi sokukhathala sandiswa izikhathi ezingaphezu kwezintathu.

• Isicelo samazwe ngamazwe

IJapan: Ngemva kokuzamazama komhlaba kwaseHanshin, isakhiwo esinde e-Osaka sasebenzisa udonga oluqiniswe nge-BF mesh, futhi ukusebenza kokuzamazama komhlaba kwathuthukiswa ngo-40%.

IYurophu: Ukhonkolo oluqinisiwe lwe-BF lwasetshenziswa emasangweni okulawula izikhukhula eVenice, e-Italy, oluphila iminyaka engama-50 ekulweni nokuguguleka kwamanzi olwandle.

• Amacala Obunjiniyela

Ibhuloho laseShayina - iHong Kong-Zhuhai-Macao: I-Basalt fiber Izinto ezihlanganisiwe zisetshenziswa engqimbeni yokulwa nokugqwala kwezinye izinsika, okunciphisa izindleko zokulungisa ngo-30%.

I-USA - I-San Francisco Bay Area Rapid Transit (BART): Indwangu ye-BF isetshenziswa ekuqiniseni ulwelwesi lwemihubhe, futhi ukumelana nokuguquguquka kwanda ngo-25%.

4. Izinselele kanye Neziqondiso Zesikhathi Esizayo

• Izinkinga ezikhona

Ukusebenza okwanele kokubopha okuphakathi: ukuxhumana phakathi kwefayibha nokhonkolo/i-resin kuthambekele ekuqhekekeni, kudingeka kuthuthukiswe izinto ezintsha zokuhlanganisa (isib., izilungisi ze-silane).

Ukuntuleka kwedatha yokusebenza kwesikhathi eside: izici zokukhukhuleka kokuqina kwe-BF ngaphansi kwezinga lokushisa eliphezulu kanye nendawo enomswakama ophezulu (idatha engaphezu kweminyaka eyi-10 ayikapheleli).

Ukufana kohlelo olujwayelekile: imininingwane yokuklama ubunjiniyela bezinto ze-BF emazweni ahlukahlukene ayikakaqinisekiswa ngokugcwele (iShayina ikhiphe i-GB/T 38143-2019, kodwa imininingwane yesicelo kufanele ilungiswe).

• Isiqondiso socwaningo lwesikhathi esizayo

Izinhlanganisela zefayibha ezihlakaniphile: izinzwa ezifakiwe ukuze kufezwe ukuqapha impilo yesakhiwo (isb., ukucindezeleka, ukuqwashisa ngokuqhekeka).

Ubuchwepheshe bokulungiselela okuluhlaza: nciphisa izinga lokushisa lokuncibilika nokudonsa (okwamanje kudinga i-1400-1500℃), bese uthuthukisa inqubo yokusebenzisa ikhabhoni ephansi.

Ukuqinisa okusebenzisana ngezinga elihlukahlukene: ukuxuba ne-carbon fiber kanye ne-steel fiber ukwakha ama-gradient composites.

5. Isifinyezo

Ukusetshenziswa kwe i-basalt fiber I-Civil Engineering isuke elabhorethri yaya ekusetshenzisweni kobunjiniyela, futhi izimfanelo zayo ezingabizi kakhulu nezinobungani nemvelo zifanelana nesidingo sezakhiwo eziluhlaza ngaphansi komgomo we-"dual-carbon". Esikhathini esizayo, kuyadingeka ukugqashula ekwenzeni ngcono i-interface, ukuqinisekiswa kokuqina kwesikhathi eside kanye nobunye ubuchwepheshe obubalulekile, futhi ngesikhathi esifanayo kukhuthazwe ukuthuthukiswa kwemininingwane yokuklama kanye nokusebenzisana kwe-industrial chain, ukuze kusheshiswe ukusetshenziswa kwayo okukhulu engqalasizinda enkulu, ubunjiniyela basolwandle, ukuvimbela ukuzamazama komhlaba kanye nezinhlekelele kanye nezinye izimo.
