Njengoba imakethe yengqalasizinda yomhlaba wonke izobuswa “ukusetshenziswa kwezinsimbi ezilula” kanye “nokusetshenziswa kwe-carbonization ephansi” ngo-2026, abaklami bezakhiwo kanye nabaphathi bokuthengwa kwempahla babhekene nesinqumo esibucayi kumaphrojekthi esakhiwo sensimbi: i-C-purlins nomaIziteshi ze-C?
Naphezu kokubonakala kwazo okufanayo, inqubo yokukhiqiza, izakhiwo zemishini, kanye nezimo zokusetshenziswa kwalezi zindlela ezimbili kuthinta ngqo ukuphepha kanye nomnotho wanoma yimuphi umsebenzi. Nasi ukuqhathaniswa kobuchwepheshe obuyisisekelo umkhakha wokwakha okudingeka ubufunde ngo-2026.
1. Inqubo Yokukhiqiza: Ebunjiwe Ngokubandayo vs. Egoqwe Ngokushisayo
Lona umehluko oyisisekelo phakathi kwalezi ziphrofayili ezimbili:
- I-C Purlin: Yenziwe kusetshenziswa imichilo yensimbi ekhandiwe esezingeni eliphezulu ngenqubo yokwakha ubanda ngokunembile. Ngokuvamile inezindonga ezincane (1.6mm kuya ku-3.2mm) futhi ifaka “izindebe” zokuthuthukisa ukuqina kwesakhiwo ngenkathi ihlala ilula.
- Isiteshi se-C: Insimbi eyakhiwe ngomshini egoqwe ngomshini. Inobukhulu bodonga obuvame ukwedlula u-5mm, okwenza kube yiphrofayili enzima engenazindebe. Yinto eyinhloko "yokuhlela okuyinhloko" enamandla amakhulu ezimboni.
2. Amandla Okuthwala Imithwalo kanye Nokusebenza Kwesikhala
Esikhathini somklamo wezakhiwo wedijithali ka-2026, izibalo ezithwala umthwalo ziye zaba nembaba kakhulu:
- I-C Purlin: Yenzelwe ngqo imithwalo esabalele. Ilungele ukudlulisa ingcindezi yophahla kanye nephaneli yodonga ohlakeni oluyinhloko lwensimbi. Kodwa-ke, ngaphansi kwemithwalo emikhulu yamaphuzu, ukuqina kwayo okugobayo kuphansi.
- Isiteshi se-C: Inikeza amandla amakhulu emithwalo emide kanye nokuqina kokuguquguquka. Ivame ukusetshenziswa njengenduku noma ikholomu yezikhala ezimfushane kuya kweziphakathi, ezikwazi ukuthwala imithwalo emikhulu yamandla adonsela phansi ngaphandle kokugoba kwendawo.
3. Ukumapha Kwesicelo Sokwakha sika-2026
| Isimo Sesicelo | Umkhiqizo Onconyiwe | Isizathu |
|---|---|---|
| Izindawo Zokugcina Izinto Ezinkulu | C Purlin | Umklamo olula unciphisa ukusetshenziswa kwensimbi iyonke; ukugqoka okwenziwe nge-galvanized kunikeza isivikelo seminyaka engaphezu kwengu-20. |
| Izisekelo Zephansi Ezinezitezi Eziningi | Isiteshi se-C | Ubukhulu obukhulu buhlinzeka ngokusekelwa okuqinile okuqondile kwezinhlelo zephansi ezisindayo. |
| Ukushintshwa kwe-PV yelanga | C Purlin | Ukucubungula okuguquguqukayo; imigodi ebhobozwe kusengaphambili ifinyeza kakhulu isikhathi sokufakwa endaweni. |
| Amafreyimu Emishini Yezimboni | Isiteshi se-C | Isakhiwo esizinzile esinokusebenza okuhle kakhulu kokushisela kanye nokumelana nokudlidliza okuphezulu. |
4. Ukuhlaziywa Kokusebenza Kahle Kwezindleko Nokwakha
Idatha yemakethe ka-2026 ikhombisa ukuthi izindleko zabasebenzi ezikhuphukayo zenze ukulula kokufakwa kwaba yisici esibalulekile.
- Isivinini Sokufaka: Ama-C Purlins avame ukubhobozwa futhi ahlanganiswe ngamabhawodi, okwenza ukwakhiwa kube ngokushesha okungaphezu kuka-30% kune-C Channels, okuvame ukudinga ukushiselwa okunzima.
- Izindleko Zokuthutha: Njengoba ama-C Purlins ayisisindo esingu-1/3 kuya ku-1/2 kuphela se-C Channels, anikeza inzuzo enkulu yokuthutha impahla kwezohwebo lwamazwe ngamazwe, okuvumela amakhasimende ukuthi andise isikhala sama-container.
Kumaphrojekthi ka-2026 abeka phambili isivinini kanye nokunciphisa isisindo (njengamapulazi elanga kanye nezindawo zokugcina impahla), i-C Purlin iyisinqumo esingcono kakhulu. Kodwa-ke, ngokusekelwa kwezakhiwo zezimboni ezisindayo kanye nezitezi eziningi, i-C Channel yendabuko isalokhu iyindinganiso yemboni yokuqina nokuqina.
