Intsimbi enokuphinda isetyenziswe kwaye igcineke
Ukususela ekuqalisweni kwayo okokuqala ngo-1915, insimbi engenasici iye yakhethwa ngokubanzi ukuba isetyenziswe kumashishini ahlukeneyo ngenxa yeempawu zayo ezibalaseleyo zoomatshini kunye ne-corrosion. Ngoku, njengoko kugxininiswa ngakumbi nangakumbi ekukhetheni izinto ezizinzileyo, insimbi engenasici ifumana ukuqatshelwa okubalulekileyo ngenxa yeempawu zayo ezintle zokusingqongileyo. Insimbi engenasici i-100% inokuphinda isetyenziswe kwaye ihlangabezana neemfuno zobomi beprojekthi enamazinga abalaseleyo okubuyisela ubomi. Ukongezelela, kubalulekile ukuqaphela ukuba ngelixa ngokuqhelekileyo kukho ukhetho olunzima phakathi kokuphunyezwa kwesisombululo esiluhlaza kunye nokuphumeza isisombululo esineendleko, izisombululo zensimbi ezingenasici zihlala zibonelela ngokunethezeka kokubini.
Intsimbi enokuphinda isetyenziswe
Insimbi engenasici i-100% iphinda isetyenziswe kwaye ayiyi kuthotywa. Inkqubo yokurisayikilisha intsimbi engatyiwayo iyafana nokuyivelisa. Ukongeza, insimbi engenasici yenziwe ngezinto ezininzi eziluhlaza, kubandakanya isinyithi, i-nickel, i-chromium kunye ne-molybdenum, kwaye ezi zinto zifunwa kakhulu. Zonke ezi zinto ziyadibana zenze ukurisayikilishwa kwentsimbi estainless ukonga kakhulu kwaye kukhokelela kumazinga aphezulu kakhulu okurisayikilisha. Uphononongo lwakutsha nje olwenziwa yi-International Stainless Steel Forum (ISSF) lubonisa ukuba malunga nama-92% entsimbi engatyiwayo esetyenziswa kwisakhiwo, ulwakhiwo kunye nolwakhiwo lwezicelo kwihlabathi jikelele iphinda ithathwe kwaye isetyenziswe kwakhona ekupheleni kwenkonzo. [1]
Ngo-2002, i-International Stainless Steel Forum yaqikelela ukuba umxholo ohlaziyiweyo wensimbi engenasici umalunga nama-60%. Kwezinye iimeko, oku kuphezulu. I-Specialty Steel Industries yaseNyakatho Melika (SSINA) ithi i-300 series steel stainless eveliswa eNyakatho Melika inomxholo ohlaziyiweyo we-post-consumer we-75% ukuya kwi-85%. [2] Ngelixa la manani ebalaseleyo, kubalulekile ukuqaphela ukuba ayisiso isizathu sokuba phezulu. Insimbi engenasici ithande ukuba nobomi obude kwizicelo ezininzi. Ukongezelela, imfuno yensimbi engenasici iphezulu namhlanje kunangaphambili. Ngoko ke, nangona izinga eliphezulu lokuphinda lisetyenziswe kwinsimbi engenasici, ubomi bangoku bensimbi engenasici kwimibhobho akwanelanga ukuhlangabezana neemfuno zanamhlanje zokuvelisa. Lo ngumbuzo omhle kakhulu.
Intsimbi ezinzileyo
Ukongezelela ekubeni nerekhodi eqinisekisiweyo yokuphinda isetyenziswe kwakhona kunye namazinga okubuyisela ekupheleni kobomi, insimbi engenasici idibana nenye inqobo ebalulekileyo yezinto ezizinzileyo. Ukuba insimbi efanelekileyo engenasici ikhethiweyo ukuze ihambelane neemeko ezinobungozi zokusingqongileyo, isinyithi esingenasici sinokusoloko sihlangabezana neemfuno zobomi beprojekthi. Nangona ezinye izinto ezinokuthi ziphulukane nokusebenza kwazo ngokuhamba kwexesha, insimbi engenasici inokugcina ukusebenza kunye nokubonakala ixesha elide. I-Empire State Building (1931) ngumzekelo omhle womsebenzi ophezulu wexesha elide kunye neendleko ezifanelekileyo zokwakha insimbi engenasici. Isakhiwo siye safumana ukungcoliseka okunzima kwiimeko ezininzi, kunye neziphumo zokucoca eziphantsi kakhulu, kodwa insimbi engenasici isabhekwa njengeyona meko ilungileyo[iii].
Insimbi engenasici - ukhetho oluzinzileyo kunye noqoqosho
Eyona nto ichulumancisayo kukuba ukuqwalasela ezinye zezinto ezifanayo ezenza intsimbi engatyiwayo ibe lukhetho lokusingqongileyo inokwenza ukuba ibe lolona khetho lubalaseleyo kwezoqoqosho, ngakumbi xa kujongwa ixabiso lobomi beprojekthi. Njengoko kukhankanyiwe ngaphambili, i-stainless steel designs inokwandisa ubomi beprojekthi nje ukuba insimbi efanelekileyo ekhethiweyo ikhethwe ukuhlangabezana neemeko zokubola kwesicelo esithile. Oku, kwakhona, kwandisa ixabiso lokuphunyezwa ngokuthelekiswa nezinto ezingenabo ubomi obude. Ukongeza, insimbi engenasici kwiiprojekthi zoshishino inokunciphisa ukugcinwa komjikelezo wobomi kunye neendleko zokuhlola ngelixa ukunciphisa iindleko zokunciphisa imveliso. Kwimeko yeeprojekthi zokwakha, insimbi engenasici efanelekileyo inokumelana neendawo ezithile ezinzima kwaye igcine ubuhle bayo ngokuhamba kwexesha. Oku kunokunciphisa ukupeyinta ubomi kunye neendleko zokucoca ezinokufuneka xa kuthelekiswa nezinye izinto. Ukongezelela, ukusetyenziswa kwensimbi engenasici kunegalelo kwi-certification ye-LEED kwaye inceda ukwandisa ixabiso leprojekthi. Ekugqibeleni, ekupheleni kobomi beprojekthi, intsimbi eseleyo engenasici inexabiso eliphezulu le-scrap.
