Kwadalwa ngo Ngokwamukisa
Izinhlobo zamathangi amanzi okuvikela umlilo ziqhathaniswa: GFS, i-Epoxy, i-Galvanized kanye ne-Welded
Ukukhetha ithangi lamanzi okuvimbela umlilo akuvamisile ukuba kube umbuzo wokuthi "yiliphi elingcono kakhulu" — kuwumbuzo wokuthi isakhiwo sini esifanele isimo sezulu sendawo, indlela yokugunyazwa, iphethini yokuhlala lingasebenzi kanye nesabelomali somjikelezo wokuphila. Imindeni emine yezakhiwo ibusa izinqolobane zomlilo ezilethwayo: amathangi e-glass-fused-to-steel (GFS) aboshiwe, amathangi aboshiwe ane-epoxy-coated, amathangi ensimbi e-galvanized, kanye namathangi ensimbi ashiselwe endaweni. Wonke agcina amanzi, kodwa ahluka kakhulu endleleni uqweqwe olumelana ngayo nokugqwala, ukuthi angakhiwa ngokushesha kangakanani, indlela aziphatha ngayo ngesikhathi sezikhathi ezinde zokungasebenzi, kanye nokuthi yiluphi uhambo lwesitifiketi alulandelayo ngaphansi kwe-NFPA 22 kanye ne-FM Global DS 1021.
Le ndatshana ibeka lezi zinhlobo ezine ndawonye njengematriki yokuqhathanisa yezobunjiniyela. Ibhalwe njengesiqondiso sokugcinwa kwamanzi okuvikela umlilo, hhayi njengokucaphuna kwephrojekthi, futhi ayincomi oyedwa ophumelelayo jikelele. Umgomo uwukuthi unikeze onjiniyela abacacisayo uhlaka lwesinqumo abangalivikela ekubhidini, ekubuyekezweni kwe-AHJ, noma ekuthunyelweni kwe-inshorensi.
Imindeni Emine Yokwakha Ihlala Ezindaweni Ezihlukile Emakethe Yokugcina Umlilo
Izinhlobo ezine zamathangi azikho imikhiqizo eshintshisanayo enomehluko wangaphandle; zimelela ukuhwebelana okuhlukile phakathi kokulawulwa kwekhwalithi kwefektri, umsebenzi wasensimini, ukuqina kwekhodi nokubiza kwemali. I-GFS ne-epoxy zombili izinhlelo ezihlanganisiwe eziboshiwe ezihlanganiswa ngamapuleti aqedwe efektri; i-galvanized ngokuvamile iwumkhiqizo olula oboshiwe noma ohlanganiswe esitolo; insimbi ewelidiwe yenziwa futhi igcotshwe kakhulu ensimini.
Amasistimu e-modular aboshiwe asusa ikhwalithi yokumboza endaweni ayisa efektri. I-GFS ihlanganisa ungqimba lwengilazi nensimbi ku-820–930 °C, okudala ukumboza okungenazimbobo, okungeyona i-organic okungeke kuxebuke noma kugawulwe ngaphansi. I-Epoxy isebenzisa ifilimu ye-organic ezingeni lokushisa eliphansi. Zombili zithunyelwa njengamapuleti futhi ziboshwa ndawonye esizeni, okunciphisa indlela ebucayi yohlelo lwephrojekthi yomlilo.
