Umhlali waseDeltona uMhlophe uyazibuza ukuba kutheni isixeko singakhange sibe neengxoxo zoluntu ngaphambi kokuba sithathe isigqibo sokuyeka ukurisayikilisha. Kuye, kwakubonakala ngathi isixeko “sikulungele ukuyiyeka, ngokukhawuleza kwaye kungekho ncoko ingako.”

Abakhi abaninzi baye baphucula oomatshini babo bokuwelda be-TIG kule minyaka imbalwa idlulileyo, kwaye abantu abaninzi abazi ukuba baqale phi na ukwenza useto koomatshini babo abatsha be-inverter bemeko-of-art. Esi sifundo sifutshane kufuneka sinyuse isantya ngokukhawuleza kwaye kulula.

Sixelele ukuba yeyantoni imveliso kwaye ijolise kubani. Bathini abavelisi ngayo? Oku kuthelekiseka njani neemvakalelo zakho ngayo?

IHazaribagh ilikhaya phakathi kwama-90 kunye nama-95 epesenti yazo zonke ii-tanneries e-Bangladesh kwaye, ngenxa yoko, ibambe indawo ebalulekileyo kushishino lwesikhumba oluya lunengeniso engakumbi. Ukususela ngoJuni 2011 ukuya kutsho kuJulayi 2012, abashicileli besikhumba eBangladesh bathengisela kumazwe angaphandle impahla yesikhumba nesikhumba ephantse ibe zizigidi ezingama-R663—ezifana nezihlangu, iibhegi, iisutikheyisi namabhanti kumazwe ayi-70 ehlabathini lonke, kuquka iTshayina, uMzantsi Korea, iJapan, iItali, iJamani, iSpeyin. , kunye neUnited States. Kwiminyaka elishumi edlulileyo, ukuthunyelwa kwesikhumba kumazwe angaphandle kuye kwanda ngomyinge wezigidi ezingama-41 zeerandi nyaka ngamnye.

"Ingqokelela ifanekisela ngokugqibeleleyo umbono womhlaba ukuya esibhakabhakeni," yatsho isitudiyo. "Umhlaba ngobugcisa bezandla, ihamile phezu kwesinyithi, ubunzima bezinto. Isibhakabhaka esinomoya, umgangatho we-ethereal wemifanekiso eqingqiweyo, njengezidalwa ezixabisekileyo ezixhonywe emoyeni."

Kutshanje i-SciAps iye yazisa i-Z, i-analyzer ephathwayo enetekhnoloji ye-LIBS. I-Z, njengoko kubonisiwe kuMfanekiso 1, inikezela ngenani eliphantsi leathom yokusebenza kwe-OES ehambayo, ngelixa igcina ukuphatheka kwe-XRF ephathwayo.

Kwi-RDG yerhasi eqinileyo, indawo yokuvelisa kwangaphambili eyayenziwe ngaphambili inyuswa ukuya kuthi ga kwi-90 yezigidi ze-scfs, ezilingana ne-15,000 imiphanda. Ukongeza, ukugqitywa kweetheminali zegesi ekupheleni konyaka-mali kuya kongeza enye i-90 yezigidi ze-scfs, ezimalunga ne-15,000 imiphanda.

Ikholamu elandelayo yimenyu yeGas Dig. Isetingi ephezulu yeyokugeleza kwangaphambili, okanye ubungakanani bexesha ofuna ukuba irhasi ekhuselayo ihambe phambi kokuba i-arc iqale. Isinye okanye ezibini zesishumi sesibini kufuneka zilungile kuninzi lwezicelo. Ukusetwa okuPhakathi kukwiPost Flow, okanye ubungakanani bexesha irhasi iqhubeka nokuhamba emva kokuba i-arc imisiwe. Isekondi enye kuzo zonke ii-amps ezili-10 sisilungiselelo esicetyiswayo. Isetingi esezantsi isetyenziselwa ukunceda ukukhusela i-electrode ukuba ingancamathiseli okanye imfutshane xa i-welding stick.

Indawo yolwakhiwo lweSikolo saMabanga aPhakamileyo esitsha sibekwe kwa-142 Murray Drive eTroutville. Isikolo siya kuvulwa ekwindla ka-2020 kwangoko.

I-Novelis, ikomkhulu lase-US, ngumenzi wehlabathi weemveliso ze-aluminiyam ezigqityiweyo kunye ne-recycler ye-aluminiyam. Isebenza kwiindawo ezininzi zokuvelisa kuMntla Melika, eMzantsi Melika, eYurophu naseAsia. I-Novelis yinkxaso-mali ye-Hindalco Industries Limited, umthengisi ose-Indiya we-aluminiyam nobhedu.

Imithombo yesekondari-kubandakanya uphando lwezifundo, iingxelo zeprojekthi, kunye nosasazo lweendaba-yaphononongwa kwaye yabandakanywa ukuxhasa ulwazi oluvela kubahlali okanye abasebenzi be-tannery. Le ngxelo ibandakanya inani lemithombo yesibini ukusuka kwi-1990s: ezi zikhethwe ngamabomu ukubonisa ubude bexesha apho le miba ixoxwe esidlangalaleni. Uphando lwakutsha nje luxhasa iziphumo zolu phando lwangaphambili kwaye lukwaqukiwe kule ngxelo. Imithetho kunye nemigaqo-nkqubo yase-Bangladeshi nayo yaphononongwa.
