Uma i-corten steel igqwala, izohlala isikhathi esingakanani?

Umsuka we-corten.

I-Corten steel iyinsimbi ye-alloy. Ngemuva kweminyaka eminingana yokuchayeka ngaphandle, ungqimba lokugqwala oluminyene kakhulu lungakhiwa phezulu, ngakho-ke aludingi ukupendwa ukuze luvikeleke. Igama elaziwa kakhulu lensimbi yesimo sezulu yi-"cor-ten", okuyisifinyezo se-"corrosion resistance" kanye "nokuqina kwamandla", ngakho-ke ngokuvamile ibizwa ngokuthi "Corten steel" ngesiNgisi. Ngokungafani nensimbi engagqwali, engakwazi ukugqwala ngokuphelele, insimbi yesimo sezulu i-oxidize kuphela ebusweni futhi ingangeni ngaphakathi, ngakho-ke inezindawo eziphakeme zokulwa nokugqwala.

I-Corten steel ihambisana nemvelo.

Insimbi ye-Corten ibhekwa “njengento ephilayo” ngenxa yenqubo yayo yokuvuthwa okungajwayelekile/yokwenza i-oxidation. Umthunzi kanye nethoni kuzoshintsha ngokuhamba kwesikhathi, kuye ngesimo sento, lapho ifakwe khona, kanye nomjikelezo wesimo sezulu umkhiqizo odlula kuwo. Isikhathi esizinzile ukusuka ekufakweni kwe-oxid kuya ekuvuthweni ngokuvamile siyizinyanga eziyi-12-18. Umthelela wokugqwala wendawo awungeni ezintweni, ukuze insimbi ngokwemvelo yakhe isendlalelo esivikelayo ukuze igweme ukugqwala.

Ingabe i-corten steel izogqwala?

Corten steel ngeke ukugqwala. Ngenxa yokwakheka kwamakhemikhali, ikhombisa ukumelana okuphezulu nokugqwala komkhathi kunensimbi ethambile. Ubuso bensimbi buzogqwala, bube ungqimba oluvikelayo esilubiza ngokuthi "i-patina."

Umthelela wokuvimbela ukugqwala we-verdigris ukhiqizwa ukusatshalaliswa okukhethekile kanye nokugxila kwezinto zayo ze-alloying. Lesi sendlalelo esivikelayo siyagcinwa njengoba i-patina iqhubeka nokukhula futhi ivuselela lapho ibhekene nesimo sezulu. Ngakho ingasetshenziswa isikhathi eside ngaphandle kokulimala kalula.
