Uphando kwimicu ye-basalt kwizicelo zobunjineli boluntu

1.Imiyalelo yesicelo engundoqo

• Izinto eziphathekayo zokuqinisa

I-Fiber Concrete (BFRC): I-Short-cut IFayibha yeBasaltI-s (6-24mm) ixutywe kwikhonkrithi (imali yokuxuba i-0.1% -0.5%), enokuphucula kakhulu ukuxhathisa ukuqhekeka (ukunciphisa ububanzi be-crack nge-30% -50%), ukuchasana kwempembelelo (ukwanda kwamaxesha angama-2-3), kunye nokuqina (i-freeze-nyibilika yokuxhathisa ibhayisekile yanda nge-40%).

Ukutshintshwa kwentsimbi yokuqiniswa kwentsimbi: Kwiindawo ezonakalisayo (umzekelo ubunjineli baselwandle), imivalo yokuqinisa ifayibha yebasalt (Imivalo ye-BFRP) inokutshintsha indawo yokuqiniswa kwentsimbi ukuphepha iingxaki ze-corrosion. Umzekelo, ukusetyenziswa kwe bfrp Ukomelezwa kwiipiers zebhulorho ewela ulwandle eQingdao kulindeleke ukuba yandise ubomi bayo ukuya kuthi ga kwiminyaka eli-100.

• Ukuqiniswa kwesakhiwo kunye nokulungiswa

Ilaphu leFayibha / iMesh Ukuqiniswa: Ilaphu le-basalt fiber (amandla e-tensile ≥2000MPa) igxininiswe ebusweni bemiqadi kunye neentsika, ezinokunyusa umthamo wokuthwala umthwalo nge-20% -30%. Umzekelo, emva kokuba ibhulorho endala eSichuan iqiniswe ngelaphu le-BF, umlinganiselo womthwalo uyanyuswa ukusuka kuNdlela we-II ukuya kwiKlasi yoku-I.

Ukomelezwa kwenyikima: imidibaniso eyomelezwe ngefayibha (BFRP) iintsika ezisongelweyo zekhonkrithi, ezinokuthi ziphucule i-ductility kunye namandla okusebenzisa amandla, kwaye zilungele izakhiwo ezikwiindawo ezithandwa ziinyikima.

• Izakhiwo ezitsha ezidibeneyo

I-Basalt fiber-polymer sandwich panels: isetyenziselwa uphahla olulula kunye neendonga zokwahlula, kunye namandla aphezulu kunye ne-thermal insulation (i-thermal conductivity ≤ 0.05 W / mK).

Izixhobo zokwakha ze-3D zokuprinta: i-basalt fiber-izixhobo zesamente ezomeleziweyo zinokuqonda ukuprintwa kwesakhiwo esinzima kunye nokunciphisa inkunkuma yokwakha.

2.Izinto eziluncedo zobuGcisa kunye neDatha engundoqo

3.Inkqubela phambili yoPhando kunye neemeko eziqhelekileyo

• Uphando lwasekhaya

IYunivesithi yaseTsinghua: iphuhliswe i-basalt fiber-nano-silica composite ikhonkrithi eguqulwayo kunye ne-25% yokunyusa amandla okunyamezela kunye ne-60% yokunciphisa i-ion ye-chloride.

IYunivesithi yaseMazantsi-mpuma: i-BF ecetywayo / i-epoxy resin laminate eyomeleziweyo yetekhnoloji yomqadi wekhonkrithi, ubomi bokudinwa bandiswe ngaphezu kwamaxesha e-3.

• Isicelo samazwe ngamazwe

EJapan: Emva kwenyikima yaseHanshin, isakhiwo esiphakamileyo e-Osaka samkela umnatha we-BF wokuqinisa udonga lokucheba, kwaye ukusebenza kwenyikima kwaphuculwa ngama-40%.

EYurophu: I-BF yasetyenziswa ikhonkrithi eyomeleziweyo kumasango okulawula izikhukhula eVenice, eItali, ubomi beminyaka engama-50 ngokuchasene nokukhukuliseka kwamanzi olwandle.

• Iimeko zobuNjineli

China-Hong Kong-Zhuhai-Macao Bridge: I-basalt fiber izinto ezihlanganisiweyo zisetyenziswa kwi-anti-corrosion layer yezinye ii-piers, ukunciphisa iindleko zokugcina nge-30%.

I-USA - iSan Francisco Bay Area Rapid Transit (BART): Indwangu ye-BF isetyenziselwa ukuqiniswa kwe-tunnel ye-tunnel, kunye nokuxhatshazwa kwe-deformation kwanda ngama-25%.

4.Imingeni kunye nezikhokelo zexesha elizayo

• Iingxaki ezikhoyo

Ukusebenza okungonelanga kokudibanisa okuphakathi kobuso: ujongano phakathi kwefayibha kunye nekhonkrithi/intlaka ithanda ukuhlutywa, ii-agent ezidibanisayo ezintsha (umz., izilungisi ze-silane) kufuneka ziphuhliswe.

Ukungabikho kwedatha yokusebenza kwexesha elide: iimpawu ze-creep zokuqinisa i-BF phantsi kobushushu obuphezulu kunye nokusingqongileyo komswakama ophezulu (ngaphezu kweminyaka eyi-10 yedatha ayikafezekanga).

Ukufana kwenkqubo eqhelekileyo: ukucaciswa koyilo lobunjineli bezinto ze-BF kumazwe ahlukeneyo ayikamiselwa ngokupheleleyo (i-China ikhuphe i-GB / T 38143-2019, kodwa iinkcukacha zesicelo kufuneka zicocwe).

• Isikhokelo sophando lwexesha elizayo

Imidibaniso yefiber ekrelekrele: izivamvo ezizinzisiweyo zokufikelela ekubekeni iliso kulwakhiwo lwempilo (umzekelo, ubunzima, ukuzazi ngokwakho).

Itekhnoloji yokulungiselela uhlaza: ukunciphisa ubushushu bokunyibilika kunye nokuzoba (okwangoku kufuneka i-1400-1500 ℃), kwaye uphuhlise inkqubo yekhabhoni ephantsi.

I-multi-scale synergistic reinforcement: ukudibanisa kunye ne-carbon fiber kunye ne-fiber fiber ukwakha i-gradient compotes.

5. Isishwankathelo

Ukusetyenziswa kwe i-basalt fiber kubunjineli boluntu iye yasuka kwilabhoratri ukuya kwisenzo sobunjineli, kunye neempawu zayo ezingabizi kakhulu kunye nezokusingqongileyo zihambelana nemfuno yezakhiwo eziluhlaza phantsi kwenjongo ye "dual-carbon". Kwixesha elizayo, kuyimfuneko ukutyhutyha i-interface optimization, ukuqinisekiswa kwexesha elide kunye nobunye ubuchwepheshe obuphambili, kwaye kwangaxeshanye ukukhuthaza ukuphuculwa kwenkcazo yoyilo kunye ne-synergies ye-industrial chain, ukwenzela ukukhawulezisa ukusetyenziswa kwayo okukhulu kwiziseko ezingundoqo, ubunjineli baselwandle, inyikima kunye nokuthintela intlekele kunye nezinye iimeko.
