Ikhwalithi ye-hot-dip efakwe ama-galvanizedUcingo olunamevainhle kuphela ebusweni bocingo olunamathiselwe ungqimba lwama-galvanized, futhi ngokuphendula kwamakhemikhali, ubuso be-zinc layer buzolahlekelwa kancane kancane umphumela ngenxa yokusabela kwe-oxidation, lesi simo sivelele kakhulu endaweni enomswakama wemvelo.Futhi ngenxa yokuthi phela, iwucingo lwensimbi olugqwalile, ngakho ikhwalithi yezintambo ezihlabayo ezishisayo-diphu ngokuqinisekile ayifinyeleli ezingeni lentambo ehlabayo yensimbi engagqwali.
Intambo enameva yensimbi engagqwali ngendlela yokugqwala ayikho kakhulu, ngoba indawo engaphezulu ayelashwa kodwa incike ezintweni zayo ezingavuthiwe ukumelana nokugqwala, ngakho-ke ngeke kube khona ukusabela kwamakhemikhali.
Ngemva kwesikhathi eside isetshenziswa, ngeke igqwale njengongqimba olunokugqwala ebusweni bentambo ehlabayo ediphu eshisayo, ngoba impahla yangaphakathi yentambo enameva yensimbi engagqwali iyafana nento engaphezulu.
Umehluko osobala kakhulu ngesikhathi esifushane ingxenye ephambanayo yalesi siqeshana, idiphu eshisayo yocingo oluhlabayo oluhlabayo ngenxa yokwelashwa kwe-anticorrosion ebusweni, ngakho-ke kuzoba nokugqwala engxenyeni ephambanayo yalesi siqeshana, nocingo oluhlabayo lwensimbi engagqwali ngoba izinto zokusetshenziswa zangaphakathi. kanye nezinto zokusetshenziswa ezingaphezulu ziyahambisana, ngakho asikho isimo esinjalo.
