Ukusuka Emhlabeni Ukuya Enyangeni Indlela Ubuchwepheshe beBasalt Fiber baseTshayina obuyichaza ngayo ngokutsha i-Aerospace Light-Weighting

Ngokuchasene nemeko yokwanda kwemfuno ye Ilula, izixhobo ezimelana nobushushu obuphezulu kwicandelo leenqwelo-moya, eTshayinaifayibha yebasaltIshishini liphumelele kwinkqubela phambili kubuchwepheshe bokuvelisa ngobuninzi beefayibha ezincinci kakhulu, kunye neempawu zokusebenza ezihambelana kakhulu neemfuno zeziseko zeenqwelo-moya. Oku kubonelela ngezisombululo eziphazamisayo zokuhlola isithuba esinzulu, ukukhuselwa kweenqwelo-moya, kunye nesiseko senyanga. Ulwakhiwo.

I. Uphuhliso lweTekhnoloji: Ukuveliswa ngobuninzi kunye nokutsiba kokusebenza kweeMicron-Scale Ultra-Fibers

Ifayibha yeBasalt yenziwe nge-basalt ore yendalo ngokunyibilika kubushushu obuphezulu kunye nokutsalwa kwi-1450-1500℃. Uphuhliso oluphambili lobuchwepheshe lubonakala kwiinkalo ezintathu:

1. Itekhnoloji yokuvelisa iMisa eZinzileyo yeeFibers eziLungileyo kakhulu
Uyilo lwe-spinneret oluyintsha: Ngokusebenzisa i-trapezoidal inner cavity ephuculweyo kunye nolawulo lobushushu oluchanekileyo olusasazwayo (impazamo ±2℃), imveliso ezinzileyo yeefayibha ezithambileyo kakhulu ezinobubanzi obuyi-Iteknoloji yokuguqula umphezulu: I-Hydroxyapatite (HA) coating kunye ne-micro-nano structure etching zisetyenziselwa ukunika iifayibha amandla okuhambelana kwezinto eziphilayo kunye nokukwazi ukuhlanganiswa kwe-biomimetic osteointegration. Kwangaxeshanye, i-silicone resin impregnation iphucula ukumelana nokugqwala, igcina izinga lokugcina amandla elingaphezulu kwe-90% kwizisombululo ze-pH 2-12.

2. Iingenelo Zokusebenza Kwiimeko Ezinzima Kakhulu
Ukumelana nobushushu obuphezulu nobuphantsi: Uluhlu lobushushu obusebenzayo bexesha elide lugubungela -269℃ ukuya kwi-700℃, kwaye lunokumelana nobushushu obuphezulu obukhawulezileyo be-1200℃ (njenge-composite felt eyenziwe nguChongqing Zhidu). Emva kweeyure ezili-1000 zokuvezwa kwi-700℃, amandla asagcina i-85% yexabiso lalo lokuqala. Umzekelo, ifayibha yebasalt Isetyenziswa kwiflegi yesizwe kumphezulu wenyanga yiChang'e-6 igcina uzinzo kwisakhiwo phantsi komahluko omkhulu wobushushu obuphakathi kwe -180℃ ne 150℃ kwicala elikude lenyanga. Amandla Aphezulu Nobunzima: Amandla okutsalwa afikelela kwi 3500-4800 MPa (adlula kakhulu i 250-800 MPa yentsimbi), kwaye uxinano luyi 2.6-2.8 g/cm³ kuphela (malunga ne 1/3 yentsimbi), ifikelela kwindibaniselwano yokusebenza "eyomeleleyo kune ntsimbi, ekhaphukhaphu kune aluminium." Emva kokusebenzisa izinto ezidityanisiweyo ze bhasalt fiber kuhlobo oluthile lwe spacecraft structure component, ubunzima bancitshiswa ngama 50%, kwaye ukumelana nempembelelo kwanda ngama 30%.

3. Ukwakhiwa kweNkqubo yoMveliso oBukrelekrele
Ukwenziwa ngcono kweDigital Twin kunye ne-AI: Ukubeka esweni iiparameters ngexesha langempela ezifana ne-melt viscosity kunye ne-fiber diameter ngokusebenzisa ii-fiber optic sensors, kunye ne-AI algorithms ukuqikelela ukusilela kwezixhobo (ukuchaneka >95%), kwandisa isivuno semveliso ukuya ngaphezulu kwe-98%. Umzekelo, isixhobo sokufumanisa esikwi-intanethi esenziwe yiHuierjie sifezekisa ulawulo lwangempela lwe-fiber diameter ye-ultra-fine, nto leyo ekhokelela ekuhambelaneni kwemveliso kufikelela kumanqanaba aphezulu aphesheya.
Inkqubo Yokuvelisa Indalo: Ngokusebenzisa ubuchwepheshe bokuhlela i-AI ore, umlinganiselo we-ore efanelekileyo unyuke ukusuka kwi-30% ukuya kwi-65%, iindleko zezinto eziluhlaza zehla nge-25%, kwaye ukusetyenziswa kwamandla kwiyunithi kwehle nge-40%, ngelixa kufezekiswa ukuphinda kusetyenziswe i-100% yeentsalela zenkunkuma.

II. Izicelo zeenqwelo-moya: Ukugubungela Zonke Iimeko ukusuka kwiNzulu yoPhando lweSithuba ukuya kwiZiseko zeNyanga

Ngenxa yeempawu zayo "zokumelana nobushushu obuphezulu, ukumelana nemitha, kunye nokuguquguquka okunamandla koyilo," i-basalt fiber ifikelele kwimpumelelo emininzi kwicandelo leenqwelo moya:

1. Inkqubo yoKhuseleko loBushushu beSiphekepheke
Ukhuseleko Lokungena Kwakhona Emoyeni: Ifayibha yeBasalt Ii-composites ze-ceramic matrix eziqinisiweyo (C/SiC) zisetyenziswa kwisikhuselo sobushushu se-capsule yokubuyisela, ezikwaziyo ukumelana namaqondo obushushu aphezulu e-1600℃, ukunciphisa ubunzima nge-20% kunye nokuqhuba kobushushu nge-30% xa kuthelekiswa nezinto zemveli ze-carbon-carbon. Emva kokusebenzisa le nto kuhlobo oluthile lwe-capsule yokubuyisela, ukutshintsha kobushushu ngaphakathi kwe-capsule kwalawulwa ngaphakathi kwe-±5℃.
Ukuthintela Okugqithisileyo Kwindalo: Umaleko wokuthintela ubushushu we-capsule ye-Chang'e 6 lander usebenzisa i-basalt fiber felt, ethintela ngempumelelo ukudluliselwa komahluko wobushushu phakathi kokukhanya kwelanga ngqo kumphezulu wenyanga (127℃) kunye necala elinomthunzi (-183℃), iphucula uzinzo lobushushu bezixhobo ezingaphakathi kwi-capsule ngama-40%.

2. Izakhiwo kunye neenxalenye zeenqwelo-moya
Izinto Ezilula Zesakhiwo: Ii-composites ze-basalt fiber/epoxy resin zisetyenziswa kwiibrakethi zesathelayithi nakwiifreyimu zephaneli yelanga. Ngoxinano lwe-1.8 g/cm³ kuphela, zinciphisa ubunzima ngama-40% xa kuthelekiswa nee-alloys ze-aluminium, ngelixa zandisa ubomi bokudinwa ngaphezu kwesibini. Umzekelo, isathelayithi ethile yonxibelelwano esebenzisa le nto inciphisa ubunzima bayo iyonke nge-120 kg, yanciphisa iindleko zokuqalisa nge-15%.
Izinto Ezimelana Nobushushu Obuphezulu: Ii-alloys ezisekelwe kwi-nickel eziqiniswe ngefayibha ye-basalt zisetyenziswa kwiiblade ze-turbofan zenjini, zinyusa ubushushu bokusebenza nge-150°C, ziphucula ukusebenza kakuhle kwepetroli nge-3%, kwaye zandisa ubomi beblade ngama-20%. Iqela lophando laseRashiya lenze iipayipi zeplastiki ze-basalt, ezibonisa ukufuduka kwe-axial okuphantsi kakhulu kunee-aluminium alloys kubukhulu obufanayo bodonga, nto leyo eyenza ukuba zifaneleke kwiinkqubo zokuhambisa amafutha erokhethi.

3. Ukuhlola Isithuba Esinzulu kunye noKwakhiwa kweSiseko seNyanga
Ukwenziwa Kwezinto Ezikwindawo Engaphezulu Kwenyanga: Amaqela ophando aseTshayina alinganise ukwakheka komhlaba wenyanga ukuvelisa iifayibha zebasalt kwaye aphuhlise izixhobo zokwenza iifayibha ezizenzekelayo. Oku kuvumela ukuveliswa kwezinto zokwakha (ezifana neepleyiti kunye neepayipi) kumphezulu wenyanga kusetyenziswa izixhobo zasekuhlaleni, kunciphisa iindleko zokuthutha nge-90% xa kuthelekiswa nokuthutha izinto ezivela eMhlabeni. Ifayibha yebasalt esetyenziswa kwiflegi yaseTshayina kwiChang'e 6 inokufana kwe-85% kokwakheka komhlaba wenyanga, okubonelela ngokuqinisekiswa kwezinto zokwakha zokwakha zenyanga ezizayo.
IiSuti zasesibhakabhakeni kunye neNkxaso yoBomi: Imikhono enithiweyo yefayibha yeBasalt Zisetyenziswa kumaleko wokhuseleko lobushushu lweesuti zasemkhathini, ezimelana ne--196°C kwindawo yeoksijini yolwelo kunye nokutshizwa kwesinyithi okunyibilikisiweyo. Ziphuculwe ngomaleko wefoyile ye-aluminium edityanisiweyo, zibonelela ngokhuseleko lwemitha, zithintela i-99% yemitha ye-cosmic. Isuti ethile yasemkhathini yovavanyo esebenzisa le nto inciphise ubunzima bayo iyonke nge-18 kg kwaye yaphucula ukuhambahamba kwayo nge-25%.

III. Ukusuka "ekuguquleni ilitye libe yigolide" ukuya "kwiinkwenkwezi nolwandle," izinto ezintsha zeBasalt zikhokela inguqu yeenqwelo-moya

Inkqubela phambili yeTshayina kubuchwepheshe bokuvelisa ngobuninzi beefayibha ze-basalt ezinobukhulu be-micron obuyi-1,000 zeetoni ayibonisi nje kuphela ukutsiba kwelizwe lam ukusuka "ekulandeleni" ukuya "ekukhokeleni" kwintsimi yefayibha esebenza kakhulu kwihlabathi liphela, kodwa ikwabonelela ngenkxaso esisiseko ebalulekileyo yokuhlola isithuba esinzulu, ukwakhiwa kwesiseko senyanga, kunye nokukhuselwa kweenqwelo-moya zesizukulwana esilandelayo. Eli "litye eliluhlaza," elivela nzulu ngaphakathi koMhlaba kwaye lenziwe kumaqondo obushushu aphezulu kakhulu, liphinda libhale ingqiqo yeendleko kunye nokusebenza kakuhle kokwenziwa kweenqwelo-moya ngeempawu zalo ezibalaseleyo: zinamandla kunentsimbi, zikhaphukhaphu kune-aluminium, kwaye ziyamelana notshintsho olukhulu lobushushu.
