Umqondo we-corten steel

Insimbi ye-Corten iwuhlobo lwensimbi olungasetshenziswa emkhathini ngaphandle kokusetshenziswa kwanoma yimuphi upende noma ezinye izinto ezivikelayo. Insimbi inokumelana okuqinile nokuguguleka komkhathi, ukuqina okuhle, ukucutshungulwa okuhle nokuvumelana nezimo okuqinile. Ngaphansi kwezimo zemvelo, ngaphansi kwesimo sezulu, ukugeza kwemvula, imvula yeqhwa, iqhwa, isengakwazi ukugcina izakhiwo zayo zemishini futhi igcine isakhiwo siqinile isikhathi eside.
Njengamanje, izinsimbi ezivamile ze-corten ekhaya naphesheya zihlanganisa: insimbi ye-galvanized corten, insimbi ye-galvanized corten steel eshisayo, insimbi engena-chromium passivated corten kanye nensimbi efuthwe. Phakathi kwazo, ezintathu zokuqala zingamapuleti ensimbi ajwayelekile e-corten, kuyilapho insimbi efafaziwe ye-corten ingeyamapuleti ensimbi akhethekile futhi idinga ukucutshungulwa okukhethekile.

Ukuthuthukiswa kwe-corten steel

Insimbi ye-Corten yavela kuma-70s wekhulu lama-20, esetshenziselwa ikakhulukazi izindonga zangaphandle, uphahla nezinye izingxenye zokuhlobisa izakhiwo. Phakathi nenqubo yokukhiqiza i-corten steel, ifilimu ekhethekile yokugqwala izokhiqizwa ebusweni bayo, enezinga elithile lokumelana ne-oxidation nokumelana nesimo sezulu, futhi i-gloss yayo inhle kakhulu, okwandisa ubuhle besakhiwo.
IBrithani, i-United States, iSoviet Union yayifunda ekuqaleni kweminyaka engamashumi ayisithupha ekhulwini lama-20. Ngasekupheleni kweminyaka yama-70 yekhulu leminyaka elidlule, i-United States yakha insimbi engamelana nesimo sezulu. I-United States kanye ne-Soviet Union bathuthukise ngokulandelana izinsimbi ezingenasici ze-austenitic ezifana nokuqina okuphezulu, insimbi ye-corten eqinile, njengensimbi engagqwali ene-asidi, ngasekupheleni kwawo-80s nasekuqaleni kwawo-90s. Insimbi ephezulu ye-nickel-chromium corten iwuhlobo olusha lwezinto ezazisetshenziswa kakhulu ngeminyaka yawo-70s, ngakho-ke idonse ukunaka ekhaya naphesheya. Eminyakeni yamuva nje, iChina nayo yenze intuthuko enkulu kulo mkhakha. Kuye kwathuthukiswa uchungechunge lwezinhlobo ezahlukene kanye namabanga ensimbi.

Yini okufanele siyinake lapho siyisebenzisa?

Ezinsimbi ze-corten, ngokuvamile ziphathwa ngaphandle futhi azikwazi ukuthintana nezinto ezidliwayo ezine-asidi noma ezine-alkali. Ngaphezu kwalokho, ezindaweni ezonakalisayo, kufanele kuthathwe izinyathelo zokuzivikela ezihambisanayo ukuze kugwenywe ukugqwala. Ukuze uvimbele ukugqwala, ukungcola nokugqwala ongqimbeni lwe-anti-rust kumele kususwe. Ngesikhathi esifanayo, okuqukethwe kwekhabhoni ezintweni ezingavuthiwe kufanele kulawulwe ngokuqinile, futhi ukwakheka kwayo kwamakhemikhali kanye nezakhiwo zemishini kufanele kulawulwe. Ikakhulukazi ohlelweni lwe-welding, insimbi ephezulu, ukumelana nokugqwala kufanele kukhethwe. Ngezingxenye zensimbi ye-corten, ukushuba nesisindo sazo kufanele kuhlolwe njalo ukuze kuvinjelwe ukugqwala.

Isiphetho

Ukuvela nokuthuthukiswa kwe-corten steel kuphawula intuthuko enkulu yemboni yensimbi yaseShayina futhi isibe wuphawu olubalulekile lwemboni yensimbi yaseChina. Ukusetshenziswa kwensimbi ye-corten kugxilwe kakhulu emikhakheni yokwakha, izinsiza zasolwandle kanye neminye imikhakha, futhi nakuba insimbi ye-corten isetshenziswe kabanzi embonini yezokwakha, insimu yayo yokusetshenziswa ilinganiselwe kakhulu ngenxa yokumelana nokugqwala kwe-corten steel ngokwayo kanye nezinye. izici. Isibonelo: amapulatifomu angasogwini, izindawo zasolwandle ezinokugqwala okuqinile kolwandle. Ngakho-ke, izindlela zokuthuthukisa i-corten steel yilezi: i-zinc eshisayo, i-aluminiyamu eshisayo, njll., esikhundleni sensimbi yendabuko ye-corten. Ngokuthuthuka kwezimboni kanye nokwenza ngcono ukuqwashisa kwabantu ngokuvikelwa kwemvelo, i-corten steel iye yasetshenziswa kabanzi embonini, kwezokwakha nakwezinye izimboni, ukufeza isimo esiphumelelayo emphakathini nasemnothweni.
