Izikhaya Zokugcina Zinakha Ngamathuba Okusebenzisa Izingxenye Ezisemthwakathini?

Ngani we-Steel Owathunywa Kabusha Yilokho Okhethwe Ngokuvamile Ngokwesikhundla Sokubeka Isikhundla Esitsha

Ukuhlanzwa, ukudura, nokuvikela kwezilwanyana: ukufikiswa kwezimfundo zokusebenza kwe-hangar zokusebenza kwe-aviation

Kukusakaza kwehangari ezingeni lezintandokazi, isitayile esisuse kwezinto ezisemthwakathini sibonakala ngokuthi sinezindawo zokubamba ngokuphelele. Lokhu kuchaza ukuthi isitayile sinezindawo zokubamba ngokuphelele kodwa kungafani nesikhundla esingaphansi, futhi sibhekise izinkinga zokuphuma kwamafire ngokulingana nokunye okufanayo. Abasakazi be hangari bafuna ukuthi isitayile sibone amaspace amakhulu angaphansi ngaphandle kokuthi amacolumns asibeke impilo yabo. Amashini amaningi ayisikwele esikhundleni esingaphezu kwe-200 feet, okuyabiza indawo enkulu kakhulu kubazali ukuthi baphinde baphinde kumashini kusakaza kwezinto noma kugcina izinto zokusebenza. Lokhu kubalulekile kakhulu ngoba akukho muntu ofuna izinto ezizimela ukufinyelela kwezinto zokusebenza ezinengqondo. Isitayile sibonakala ngokuphelele ngokulingana nokubhakisha noma isidlali uma kubhakisha kakhulu. Kuzo zizinkinga zokuphuma kwamafire wezithelo zokuhamba, isidlali sibhakisha futhi isidlali sibhakisha, kodwa isitayile sibhakisha ngokuphelele emhlabeni wokuphuma kwamafire. Lokhu kuyisibonelo sokuthi amadola amaningi ayisicela isitayile esisuse kwezinto ezisemthwakathini esifanayo nezindlela zokubhakisha zokuphuma kwamafire zokuthi ziyasebenza ngokuphelele kwi-ASTM E119. Lokhu kuchaza ukuthi lezinto ziyasebenza ngokuphelele kusukela emhlabeni wokuphuma kwamafire kusukela emva kwezinsuku ezimbili, okuyabiza indawo kubazali ukuthi baphume futhi bakholise izinto ezinengqondo. Futhi, ngokusebenzisa izinkampani ezihlukahlukene nezinkampani zokubhakisha, isitayile asibhakishi ngokuphelele nakwezindawo zokubhakisha kwezilwane zokubhakisha. Izinhlangano zokubhakisha ezisakaza kulezi zinto ziyasebenza ngokuphelele kusukela emva kwezinsuku eziningi, futhi ziyasebenza ngokuphelele kusukela emva kwezinsuku eziningi.

Isibonelo sokusebenza kuzo zonke izinsuku: Ukubuyiselwa kuzo zonke ngokuphelele ngaphandle kokuguqula kwezinkundla zabo

Yini okwenza indawo yokusebenzisa isitayile esisuswanga kakhulu? Ukuthi kungasebenziswa kabusha ngokuphinda ngokuphinda ngaphandle kokukhupha ukuthi kuyisibonelelo noma ukuthi kuyisifunda. Ngasinye isikhathi esisuswangwa, kuyabeka konke ukuthi kuyisibonelelo sokubamba nokuthi kuyisifunda, kodwa kufuneka kuphela umbhalo wemithambo yezinkulungwane ezingama-4 yokusebenzisa imisebenzi yokwenza isitayile esisha ngokuphathwa kwakho. Amanani ayabona le mbono futhi — ngokwesibonelo, amazinkulungwane e-80 ayasuswangwa ngonyaka ngaso sonke emerika ngokwesibonelo sikaSteel Recycling Institute. Khumbula lezinhlangano zomkhumbi ozimele ezihlala emaphoyinteni noma emizini yezindawo zokusebenza. Akahleli kulezo zindawo zokugcina umsebenzi wazo ngokuzimela njengoba kuyadlula. Uma lezi zinhlangano zifika ekupheleni kwemisebenzi yabo, konke okubiliwe kungasuswa futhi kubuyiselwa ku-isitayile esihle kakhulu sokwakha. Le ndlela yoku-suswa iyanciphisa amakhemikhali okugqibela ngokuphinda-phinda kusukela kumithambo yezinkulungwane ezingama-2 kusukela kuma-3 uma kuchazwa nezindlela zokwakha zokusebenzisa izinto zokwakha. Futhi lapho kukhona umphumela: sizifuna ukuthi sibe nesibonelelo esihle kakhulu sokusebenza esifunekayo kumasevisi okwemvelo, futhi inkulumo yethu ibuyela kuvutha ngaphandle kokuthi sibuyela kususa izinto zokwakha zokudala.

Izinkulungwane Zokuthuthukisa Ezisetyenziswa Kwe-Envelopes Yehangar Nezinkampani Zokubhala

Izinkampani Zokuthuthukisa Zokubhala Zokuphinda Ziyasebenza Ngokuphelele Nezinkampani Zokubhala Zokuphinda Ziyasebenza Ngokuphelele Nokubambisana Kwabantu

Amapaneli enziwe nge-aluminium-bamboo anikeza okuthile okukhethekile ezintweni zokwakha namuhla. Lezi zinhlaka zihlanganisa amandla asezingeni lezindiza nezinzuzo ezinkulu ezingokwemvelo. Zenziwe okungenani nge-aluminium esetshenziswe kabusha engu-85% exutshwe nezintambo zikamabhambo ezikhula ngokushesha, zisinda cishe isigamu sesakhiwo sensimbi. Lokhu kwenza kube lula kakhulu ukuwafaka endaweni futhi kunciphisa kakhulu isidingo sama-crane abizayo phakathi nemisebenzi yokwakha. Zidlula kuzo zonke lezo zivivinyo ezinzima zemithwalo yomoya nemiphumela njengoba kuchazwe yizindinganiso ze-ASTM E330 ne-E1886. Ngaphezu kwalokho, la maphaneli ahlala eqinile ngisho nalapho izinga lokushisa lishintsha phakathi kuka-40°C no-120°C. Nokho, okuphawuleka ngempela yizitifiketi zabo eziluhlaza. Ukukhiqiza i-aluminium esetshenziswe kabusha kukhiqiza amathani angu-0.8 kuphela e-CO2 ngethani ngalinye ngokusho kocwaningo lwe-International Aluminium Institute kusukela ngo-2023. Lokho kungukunciphisa okukhulu okungama-95% uma kuqhathaniswa nokwenza i-aluminium entsha kusuka ekuqaleni. Futhi ungakhohlwa nengxenye yensimbi. Empeleni, insimu yensimbi imunca cishe u-70% ngaphezulu we-carbon dioxide emoyeni ngehektare ngalinye kunamahlathi avuthiwe avuthiwe. Ngakho-ke lokho esikutholayo lapha akuyona nje impahla yokwakha eqinile kodwa into esiza ngempela ukuphulukisa iplanethi yethu ngenkathi simelana nakho konke imvelo ekujikijela kukho.

Izinhlelo Zokubhala Zokugcina Ezinamandla Okungabi Nge-Carbon

Isizukulwane sakamuva sezakhiwo ezakhiwe ngaphandle asisekho nje ngokunciphisa ukukhishwa kwe-carbon. Lezi zinhlelo ezintsha empeleni zikhipha i-CO2 ngqo emoyeni esiwuphefumulayo. Ngokwesibonelo, cabanga ngamapaneli aqiniswe nge-mycelium. Ngokuyisisekelo zikhulisa isakhiwo sazo kusuka emfucumfucwini yezolimo esele, zibamba ikhabhoni ngaphakathi kwazo kuyo yonke impilo yesakhiwo esiyingxenye yaso. Kukhona nezinhlelo ze-resin ezenziwe ngezindwangu ezindala nezinsalela ze-pulp yezingodo eziqhubeka zithatha i-carbon ngenxa yezinqubo ezikhethekile zamakhemikhali ezakhelwe ngaphakathi. Uma kuqhathaniswa nezinto ezivamile zokumboza ezivame ukukhipha cishe amakhilogremu angu-800 we-CO2 okulingana nemitha eyisikwele, lezi zinto ezintsha empeleni zisusa amakhilogremu angu-120 we-CO2 okulingana nemitha eyisikwele eminyakeni engamashumi amathathu ngokusho kokuhlolwa kwemvelo okuzimele. Ngaphezu kwalokho, zonke lezi zinto zidlula emithethweni eqinile yokuphepha emlilweni futhi ziyowohloka ngokuphelele lapho isikhathi sazo sokusebenza siphela. Cabanga ukuthi kwenzekani lapho othile efaka lezi zinhlelo ehhanjini elikhulu elihlanganisa amamitha-skwele angu-10.000. Umphumela wokunciphisa i-carbon uyofana nokususa izimoto ezingu-350 emigwaqweni yethu unyaka ngamunye ngokwezibalo zamuva ze-EPA. Ngokungazelelwe, lezo zakhiwo ezinkulu zezindiza azisabi zimbi nje kuphela emvelweni kodwa esikhundleni salokho ziba izixazululo zangempela zokubamba i-carbon.

Ukulinganisa Imiphumela Yokuqinisekisa Ukuthula: I-Carbon Ekhululekile Nezidingo Zokuphila Kwamaphoyisa Okusebenzisa Amathuba Okuzokwa

Uma kuziwa emikhubeni yokwakha eluhlaza, ama-hangar enziwe ngezinto ezisetshenziswa kabusha ayavelela ngempela lapho sibheka ithrekhi yawo yekhabhoni kulo lonke umjikelezo wokuphila. Lokhu kuhlanganisa wonke amazinga okukhishwa kwe-CO2 kusukela ekumbeni izinto zokusetshenziswa kuze kube yilapho sekwakhiwa. Lapho abakhi beshintsha insimbi entsha ne-aluminium bayisebenzise izinguqulo ezivuselelwe eziqinisekiswe kahle, banganciphisa lokhu kukhipha i-carbon cishe ngesigamu kuya kwezintathu kwezine ngensimbi, ngisho nangaphezu kuka-80% nge-aluminium. Kungani? Ngoba asisekho isidingo salezo zinqubo ezinamandla ezifana nokumbiwa kwemayini, ukucutshungulwa kwezimbiwa, noma ukuncibilikiswa kokuqala. Ngokwesibonelo, cabanga ngendawo evamile yokugcina izimpahla engaba amamitha-skwele angu-15,000. Uma yakhiwe isebenzisa insimbi ne-aluminium okuphindwe kwavuselelwa okungaphezu kuka-90%, igcina amathani angu-300 kuya kwangu-500 e-CO2 ngaphandle komkhathi. Ukuze sikubeke kahle, yilokhu okwenzekayo lapho izimoto ezivamile ezingu-65-110 ziyeka ukushayela unyaka wonke ngokusho kwedatha yakamuva ye-EPA kusukela ngo-2023.

Iziphumo zokusebenza kwezinsuku zokuphila zihlanganisa lezi zokwakha kwanasekunquleni:

• Ukuhlanzwa kabusha ngokugcwele : Isteeli ne-aluminum zibuyela kuzo zonke iziqu zokuhlanzwa kabusha ngaphandle kokuguqula ukuthi ziyisikhundla sokusebenza, kubhekwa indawo yokugcina emhlabathini
• Ukubambisana kwesebenza : I-cladding ephumelelayo yekhophi yenhlangano yokuqinisa isikhundla sokusebenza kwezindawo, ibeka ubukhulu bekho bokusebenza kwe-HVAC ngokuphelele ngo-15–25%
• Ukubaluleka kokuhlanzwa : Izilungiselelo zokuhlanganisa ngokwezimodu nezincwadi ezifanayo zisiza ukubuyela kuzo izinto ezingu-90% noma kude—kubeka ukuhlanzwa kwezinsuku zokuphila njengendawo yokubhukuda imali kwezinhlangano zokubuyela

Le miphumela akuyona nje imibono ephepheni. Lapho abathuthukisi besebenzisa izinto ezivuselelwe eziye zaqinisekiswa nge-Environmental Product Declarations, empeleni bafinyelela imigomo yokuzinza ebekwe izinhlangano ezinjenge-FAA ne-ICAO. Ngaphezu kwalokho, le ndlela iyabasiza ukuba bahlale bephambi kwemithetho eqinile engase ivele, njengohlelo lwe-EU lwe-Carbon Border Adjustment Mechanism nezimfuneko ezintsha zikahulumeni e-United States. Uma sibheka ngenye indlela, ama-hangar akhiwe ngezinto ezisetshenziswe kabusha ahlanganisa izici eziningana ezibalulekile. Izindinganiso zokuphepha ezindizeni zisasebenza, imisebenzi ihamba kahle, futhi ukukhathalela umhlaba ngobuqotho kuhlanganiswe ngqo nomklamo. Lokhu akukhona nje ukuqondanisa phakathi kwezinhloso ezahlukene, kodwa ukuhlanganiswa kwangempela okudala okuthile okuhlala njalo futhi okuguquguqukayo kulokho okuzayo.
