Ukonga Amandla kunye nokuNcitshiswa koKhuhlane: Iingenelo eziKhaphukhaphu zeCarbon Fiber Ziya Zibonakala Ngakumbi
Ifayibha yekhabhoniiplastiki eqinisiweyo(CFRP) yaziwa ngokuba ilula kwaye inamandla, kwaye ukusetyenziswa kwayo kwiindawo ezifana neenqwelo moya kunye neemoto kuye kwanegalelo ekunciphiseni ubunzima kunye nokuphucula ukonga amafutha. Ngokwe-Life Cycle Assessment (LCA) yempembelelo iyonke kwindalo esingqongileyo ukusuka ekuvelisweni kwezinto ukuya ekulahlweni okwenziwa yi-Japan Carbon Fiber Manufacturers Association, ukusetyenziswa kwe-CFRP kunegalelo elikhulu ekunciphiseni ukukhutshwa kwe-CO2.
Ibala leenqwelo-moya:xa ukusetyenziswa kwe-CFRP ye-carbon fiber composite kwinqwelo-moya yabakhweli ephakathi ifikelela kwi-50% (njengakwi-Boeing 787 kunye ne-Airbus A350 CFRP dosage idlule kwi-50%), isixa seifayibha yekhabhoniIsetyenziswa kwinqwelo-moya nganye malunga neetoni ezingama-20, xa kuthelekiswa nezixhobo zemveli zinokufikelela kwi-20% elula, ngokutsho kweenqwelo-moya ezingama-2,000 ngonyaka, udidi ngalunye lweemayile ezingama-500, iminyaka eli-10 yokusebenza, inqwelo-moya nganye inokunciphisa iitoni ezingama-27,000 zokukhutshwa kwe-CO2 ngenqwelo-moya nganye kwiminyaka eli-10 yokusebenza, ngokusekelwe kwiinqwelo-moya ezingama-2,000 ngonyaka kunye neemayile ezingama-500 ngenqwelo-moya nganye.
Icandelo leemoto:Xa i-CFRP isetyenziselwa i-17% yobunzima bomzimba wemoto, ukunciphisa ubunzima kuphucula ukonga amafutha kwaye kunciphisa ukukhutshwa kwe-CO2 ngenani elipheleleyo leetoni ezi-5 zokukhutshwa kwe-CO2 ngemoto nganye esebenzisa i-CFRP, ngokusekelwe kumgama wokuqhuba ubomi bonke weekhilomitha ezingama-94,000 kunye neminyaka eli-10 yokusebenza, xa kuthelekiswa neemoto eziqhelekileyo ezingasebenzisi i-CFRP.
Ukongeza koku, utshintsho kwezothutho, ukukhula kwamandla amatsha kunye neemfuno zokusingqongileyo kulindeleke ukuba zidale amathuba amatsha oshishino lwe-carbon fiber. Ngokutsho kweToray yaseJapan, imfuno yehlabathi ye-ifayibha yekhabhoniKuqikelelwa ukuba iza kukhula ngesantya sonyaka se-17% ngo-2025. Kwizicelo zeenqwelo-moya, iToray ilindele imfuno entsha yefayibha yekhabhoni "kwiimoto ezibhabhayo" ezifana neekhabhi zomoya kunye needrone ezinkulu, ukongeza kwiinqwelo-moya zorhwebo.
Amandla omoya: ukusetyenziswa kwefayibha yekhabhoni kuyanda
Kwicandelo lokuveliswa kwamandla omoya, ukufakelwa okukhulu kwenzeka kwihlabathi liphela. Ngenxa yemida yendawo, ukufakelwa kutshintshela kwiindawo ezikude nolwandle nakwiindawo ezinomoya omncinci, nto leyo ebangela imfuneko engxamisekileyo yokuphucula ukusebenza kakuhle kokuveliswa kwamandla ombane.
Iiblade ezinkulu ze-wind turbine ziyafuneka ukuze kwandiswe ukusebenza kakuhle kokuveliswa kombane, kodwa kusenziwa ngokusebenzisa indlela yendabuko.i-fiberglassIi-composites zenza zibe sesichengeni sokuwa, nto leyo ebeka iiblade ze-turbine emngciphekweni wokucinezela inqaba kwaye zenze umonakalo. Ngokusebenzisa izixhobo ze-CFRP ezisebenza ngcono, ukuwa kuya kuthintelwa kwaye ubunzima buya kuncitshiswa, okuvumela ukwenziwa kweeblade ze-turbine ezinkulu kunye negalelo ekusetyenzisweni ngakumbi kwamandla omoya.
Ngokufaka isiceloifayibha yekhabhoniIi-composites ukuya kwiiblades zeeturbines zomoya zamandla avuselelekayo, kunokwenzeka ukwenza iiturbines zomoya ezineeblades ezinde kunangaphambili. Ekubeni ukuveliswa kwamandla omoya ngokwethiyori kuhambelana nesikwere sobude beblade, ngokusebenzisa ii-composites ze-carbon fiber kunokwenzeka ukufikelela kubukhulu obukhulu kwaye ngaloo ndlela kwandiswe amandla okukhupha eturbine yomoya.
Ngokutsho kohlalutyo lwamva nje lwemarike olukhutshwe yiToray ngoMeyi kulo nyaka, intsimi ye-carbon fiber blade field ye-2022-2025 ifuna i-carbon fiber compound annual rate yokukhula ukuya kuthi ga kwi-23%; kwaye kulindeleke ukuba ngo-2030 imfuno ye-carbon fiber blade turbine blade yenze i-carbon fiber ibe yi-92,000 tons.
Amandla eHydrogen: Igalelo leCarbon Fiber Liya Libonakala Ngakumbi
I-hydrogen eluhlaza iveliswa ngamanzi asebenzisa umbane kusetyenziswa umbane oveliswa kwimithombo yamandla ahlaziyekayo njengelanga okanye umoya. Njengomthombo wamandla acocekileyo onegalelo ekungathathi cala kwekhabhoni, i-hydrogen eluhlaza ibisoloko itsala ingqalelo kwaye imfuno yayo kulindeleke ukuba ikhule kakhulu kwixesha elizayo. Ukongeza, ukusetyenziswa kwayo kwiiseli zamafutha e-hydrogen kuyanda ngokuthe ngcembe kwaye kulindeleke ukuba ikhule kakhulu kwixesha elizayo.
Iisilinda zokugcina ihydrogen ezinoxinzelelo oluphezulu ezenziwe ngeefayibha zekhabhoni ezinamandla aphezulu, iphepha lefayibha yekhabhoni elisetyenziswa njengezixhobo ze-electrode kunye neeleya zokusasazwa kwegesi, kunye nezinye iimveliso zinegalelo elihle kuthotho olupheleleyo lwemveliso ye-hydrogen, uthutho, ugcino, kunye nokusetyenziswa.
Ngokusebenzisaifayibha yekhabhoniKwimithambo yoxinzelelo, efana negesi yendalo ecinezelweyo (CNG) kunye neesilinda zehydrogen, kunokwenzeka ukunciphisa ubunzima ngempumelelo kunye nokunyusa uxinzelelo oluqhumayo. Imfuno yeesilinda zeCNG kwizithuthi zeCNG ezisetyenziswa kwiinkonzo zokuhambisa emakhaya kunye neetanki zothutho lwegesi yendalo ikhula ngokuthe chu.
Ukongeza, imfuno yefayibha yekhabhoni esetyenziswa kwimikhumbi yoxinzelelo kulindeleke ukuba inyuke kwixesha elizayo njengoko iisilinda zokugcina ihydrogen zisetyenziswa ngakumbi kwiimoto zabakhweli, iilori, oololiwe, kunye neenqanawa ezisebenzisa iiseli ze-hydrogen fuel.
