Ukusetyenziswa kweeLayered Basalt Ultra-Fine Yarns kunye neeFabric zazo kwiLunar Exploration

Iphepha lophando elinesihloko esithi "Hierarchical basalt metayarn yeendwangu zokukhusela isithuba ezisemgangathweni" lipapashwe kwijenali iMatter liqela likaNjingalwazi uXia Zhigang kunye ne-Academician uXu Weilin ovela kwiNational Key Laboratory of New Textile Materials and Advanced Processing kwiYunivesithi yaseWuhan Textile, ngokubambisana noNjingalwazi uTao Guangming. Eli qela lophando lwezixhobo ezintsha zelaphu kunye nokucubungula okuphucukileyo liqale lacebisa ubuchwepheshe bokusonta obuphambili "coaxial spiral wrap spinning," obujongana nemingeni yokusonta, ukuluka, kunye nokusetyenziswa kwefayibha ye-basalt engatshabalalisiyo, ene-torque ephantsi, esemgangathweni ophezulu, kunye nenkulu kakhulu. Oku kuvula indlela entsha yokucubungula ilaphu elikhulu, elinobuhlobo nolusu, kunye nokuguquguquka kwezinto zefayibha ezingaphiliyo ezinobunkunkqele, ezivumela ukuba imveliso enkulu ihlangabezane nesidingo esingxamisekileyo sezixhobo zokukhusela eziphezulu ukumelana neemeko ezinzima nezinzima kakhulu kwi Inqwelo-moya intsimi. Umbhali wokuqala weli phepha nguNjingalwazi uXia Zhigang, kwaye ababhali abahambelana nalo nguNjingalwazi uXu Weilin kunye noNjingalwazi uTao Guangming. Eli phepha likhethwe njengenqaku elikwiphepha lejenali.

Ukusetyenziswa koluhlu lwezikhundla intambo ye-basalt ultrafine kwaye amalaphu ayo ekuhlolweni kwenyanga yimeko ebalulekileyo yokufuduka kwabantu kwixesha elizayo. Le ntambo ye-basalt ultrafine enemigangatho ibonakalisa ukuguquguquka, amandla aphezulu, kunye nozinzo oluhle kakhulu, kwaye inokulukwa ibe ngamalaphu athambileyo amelana ngempumelelo nemitha yelanga enamandla kunye nokuguquguquka okukhulu kobushushu esibhakabhakeni. Olu phando luqalise indlela entsha yokuguqula i-basalt fiber engabonakaliyo ibe yimpahla yesithuba esebenzayo, ekhuselayo ngokwe-ergonomic.

Kwiminyaka yakutshanje, ngenxa yophuhliso olukhawulezileyo lokuhlola isithuba esinzulu kwihlabathi jikelele kunye neenqwelo-moya zorhwebo, imfuno yoshishino lwe- Ilula, izinto ezimelana nokusingqongileyo kakhulu zinyuke kakhulu.Ifayibha yeBasalt, ephuma kwilitye lentaba-mlilo, ineenzuzo ezibalaseleyo ezifana neendleko eziphantsi, ukumelana nobushushu obuphezulu, ubushushu obuphezulu, ukumelana nemisebe, ukumelana nokugqwala, kunye nokungatsha ngaphandle komsi, okutsala ukhuphiswano lokusasazwa kwiindawo ezininzi kubandakanya uthutho lukaloliwe, ukhuseleko olukhethekileyo, kunye nobunjineli bokwakha. Nangona kunjalo, ukuqina kwayo okuphezulu kunye ne-modulus ephezulu kuyenza ibe sesichengeni kakhulu sokuqhekeka okubuthathaka kwinqanaba eliphezulu; ukujikeleza kwayo okune-torque ephezulu kukwabangela umonakalo wefayibha kunye nokwehla okukhulu kwamandla, okubangela ukuba intambo "engonakalisiyo, ene-torque ephantsi, egqunywe ngokupheleleyo, enobuhlobo nolusu, kwaye eguquguqukayo" ibe yingxaki yexesha elide "yebhotolo" ethintela i-basalt fiber ukuba ingene kwinkqubo yokufaka impahla.

Ixesha loPhuhliso lweTekhnoloji

Ukusombulula le ngxaki yobugcisa kunye nokuhlangabezana neemfuno zezicelo zokhuseleko olugqithisileyo, inkampani yasekhaya isebenzisene neqela likaNjingalwazi uXia Zhigang kwiYunivesithi yaseWuhan Textile. Bajongana nayo yonke inkqubo yemizi-mveliso, ukusuka ekusonteni, ekwenzeni intambo, ekulukeni, ukuya ekudayini:

• 2019: Ukuqala kokucetywa kokusonta okungonakalisiyo.

• 2020: Ndayiphuhlisa ngempumelelo eyokuqala enobuhlobo nolusu ilaphu lokukhusela ubushushu le-basalt fiber.

• 2021: Ifezekisile iteknoloji yokuzoba elawulwa ngokuchanekileyo kwifayibha ye-basalt ecolekileyo kakhulu esetyenziswa kwimpahla.

• 2022: Ilebhu iyile kwaye yajikeleza ngempumelelo umgangatho ophezulu, i-torque ephantsi, ayitshabalalisi, igqunywe ngokupheleleyo, inomlinganiselo ophezulu intambo entle yefayibha yebasalt.

• 2023: Ukusebenza okuzinzileyo kweseti epheleleyo yeenkqubo kunye nezixhobo ezifanelekileyo zokujikeleza i-basalt fiber engatshabalalisiyo, egubungela ngokupheleleyo.

• 2023 ukuza kuthi ga ngoku: Ukuphuculwa okuqhubekayo kunye nokuphuculwa kweenkqubo kunye nezixhobo, ukwamkela iiodolo zemveliso, kunye nokuphuhlisa amalaphu okukhusela i-basalt fiber aphezulu kwiimeko zokhuseleko olugqithisileyo.

• 2024: Iflegi yesizwe saseTshayina eyenziwe ngefayibha yebasalt, eyaphuhliswa yiYunivesithi yaseWuhan Textile, yavulwa ngempumelelo kwicala elikude leNyanga ngumsebenzi weChang'e-6, nto leyo eyakhuthaza ngakumbi ingqalelo kunye nokwandiswa kwempahla yokukhusela ibasalt.

• 2025: Iqela lokuvelisa izinto ezintsha elithi "Basalt Fiber Era" lasekwa ngokudibeneyo yi-Aero-Engine Corporation yaseChina Hangyu Life Support Equipment Co., Ltd. kunye neqela le-Academician Xu Weilin elijikeleza kwiYunivesithi yaseWuhan Textile. Eli qela lizinikele kuphando olunzulu kunye nokukhuthaza ukwandiswa kwe-basalt fiber kwi-aerospace, ukusuka kwizixhobo eziluhlaza ukuya kwiimveliso zelaphu, ukujongana nemida yesayensi yesithuba yamazwe ngamazwe kunye neemfuno eziphambili zesicwangciso selizwe.

Uyilo kunye nokusebenza

Bekhokelwa ngooNjingalwazi uXu Weilin, uXia Zhigang, kunye noTao Guangming, kunye nabafundi abaphumelele izidanga abanjengoShang Lulu, uXu Ao, kunye noZhang Shiliang, iqela liqhubeke nokuvelisa izinto ezintsha nokuphucula iteknoloji yangoku. Baye baba ngabaqalisi betekhnoloji "yokusonta i-coaxial spiral wrap", boyisa izinto ezintsha zobugcisa nezixhobo ezinje ngokwakhiwa kwentambo engatshabalalisiyo, engaphantsi kwe-torque kunye nokugubungela okuzinzileyo kwamanqanaba amaninzi.

Baphumelele ukuveliswa rhoqo kwe-multilevel, organic-inorganic composite, elungele ulusu, neguquguqukayo ye-basalt meta-structural yarn (Metayarn) ngokwezinga lemizi-mveliso.

• Amandla eMetayarn eveliswayo anyuke ngama-27.76% xa kuthelekiswa ne-basalt filament yokuqala.

• I-torque eseleyo yentambo incitshiswe kakhulu xa ithelekiswa nezinye iintambo zorhwebo, nto leyo evumela ukuluka ngokuthe ngqo okanye ukuluka kwiimveliso zeMetayarn ezinobuhlobo nolusu neziguquguqukayo.

Ijongene neendawo ezintsonkothileyo nezinzima zeenqwelo-moya, iimveliso zeMetayarn zibonisa ukuzinza okubalaseleyo kokusingqongileyo kunye nozinzo lwesakhiwo:

• Amandla emveliso eguquguqukayo awazange aphele, kodwa anda kakhulu, emva kokuhlamba rhoqo nge-nitrogen engamanzi kwi-200°C, umoya oshushu kwi-300°C, kunye nokuvezwa ixesha elide kwimitha enamandla yelanga.

• Yagcina isakhiwo sayo siqinile emva kokuba itshiswe lilangatye elishushu kakhulu kwi-1300°C.

• Iimveliso ezilukiweyo zeMetayarn zinobude obude xa ziqhekeka ukuya kuthi ga 421%.

• Zigcina ubushushu obugqwesileyo bomlilo kunye nokumelana nomlilo nokuba zingaphantsi kwama-30 degrees%, ukufezekisa umsebenzi odibeneyo "wokuthuthuzela nokukhusela."
