Ngokuthambekela kokubukeka kwemboni, kunentshisekelo evuselelwe kunsimbi yesimo sezulu. Insimbi yesimo sezulu, eyaziwa nangokuthi insimbi yesimo sezulu, inokubukeka kwesimo sezulu esingokwemvelo nokugqwala. Idala intshisekelo nokuthungwa ngenkathi ihambisana nokubukeka kwemboni noma kobunjiniyela.

Njenganoma iyiphi enye impahla yokwakha, insimbi yesimo sezulu inezinzuzo nezinkinga. Kubaluleke kakhulu ukwazi ukuthi iyini insimbi yesimo sezulu kanye nezakhiwo zayo.

Iyini insimbi yesimo sezulu?

Insimbi yesimo sezulu, ngezinye izikhathi ebizwa ngokuthi i-weathering steel, iwuhlobo lwensimbi yesimo sezulu esimelana nokugqwala. Ngenxa yekhono layo lokwenza uqweqwe oluvikelayo lokugqwala, insimbi yesimo sezulu iyinketho ethandwayo yokuqoshwa kwangaphandle, ukwakheka kwezwe, ama-facade esakhiwo nezinye izinhlelo zokusebenza zangaphandle. Ungqimba oluvikelayo, olubizwa ngokuthi i-verdigris, lwakha phakathi nezinyanga eziyisithupha nje zokuchayeka kumoya-mpilo nomswakama.
I-Verdigris, ekhiqiza uqweqwe olunsundu ngokumnyama, ivikela insimbi ekugqwaleni okwengeziwe emvuleni, iqhwa, inkungu, iqhwa, iqhwa nezinye izimo zezulu. Ngamafuphi, ukugqwala kwensimbi, nokugqwala kwakha uqweqwe oluyisivikelo. Lesi sendlalelo sisebenza kakhulu uma sivunyelwe ukuzinza nokwakha ngokuhamba kwesikhathi.

Ukuze ukhiqize i-patina evikelayo, insimbi kufanele ivezwe emanzini nomoya-mpilo. Lapho insimbi ichayeke ezakhini, lokhu kugqwala okuyisivikelo kuthatha izinyanga ezimbalwa kuphela ukwakha. I-coating inamandla futhi iyaqhubeka nokuvuselela ngaphansi kwezimo zezulu ezahlukene.

I-Cor-ten igama lezohwebo eliphethwe yi-US Steel elichaza izinzuzo ezimbili ezikhangayo eziyinhloko ze-Steel: ukumelana nokugqwala namandla aqinile. Yasungulwa ngeminyaka yawo-1930 ukusiza ukwakha izinqola zamalahle zikaloliwe.

I-adventure yenqola yamalahle yaba yimpumelelo, futhi i-Cor-Ten steel yaba into ethandwayo yokukhethwa kwezithombe eziqoshiwe zobuciko zangaphandle ngawo-1960.

Ngaphezu kokumelana nokugqwala, insimbi ye-weathering iqeda isidingo sikapende noma isimo sezulu esingeziwe.

Kungani i-weathering steel ivikela?


I-patina eyakhiwe ngensimbi yesimo sezulu inesendlalelo sangaphakathi nangaphandle. Isendlalelo sangaphandle sihlala sishintsha futhi sakhiwa kabusha ngemikhiqizo emisha yokuvimbela ukugqwala okunganamatheli. Ungqimba lwangaphakathi lwakhiwe ikakhulukazi izinhlayiya ezinhle eziminyene.

Ekugcineni, ungqimba lwangaphandle luyancipha ukusebenza futhi ungqimba lwangaphakathi luqala ukugqama kakhulu. Yilokhu okunikeza i-weathering steel ukubukeka kwayo okuyingqayizivele nokuthungwa kwayo. Izingqimba zangaphandle zaqina, futhi izingqimba zangaphakathi zaba minyene.


Isendlalelo sangaphakathi ngokuyinhloko sakhiwe i-goethite engeyona yesigaba, yingakho insimbi yesimo sezulu inezindawo zokuzivikela. Kungani kunjalo? Ngoba umkhiqizo ogqwalile uba uminyene kangangokuthi amanzi awasakwazi ukugqwala isakhiwo sensimbi sangaphakathi.

Uma isithuthukisiwe kahle, ungqimba lwangaphandle lwensimbi yesimo sezulu kufanele lube bushelelezi futhi luzizwe njengengubo evikelayo.
