Sonke siyazi ukuthi insimbi evamile izogqwala uma ivezwa emoyeni wangaphandle isikhathi eside, ngakho-ke ungakugwema kanjani ukugqwala? Ngaphambi kokuphuma efektri, izigxobo zokukhanyisa emgwaqweni kudingeka zicwiliswe ngokushisa bese zifafazwa ngepulasitiki, ngakho-ke iyini inqubo yokufaka i-galvanizing ye-izinsika zokukhanyisa emgwaqweniNamuhla, ifektri yezigxobo zezibani zasemgwaqweni i-TIANXIANG izothatha wonke umuntu ukuba ayiqonde.
Ingxenye ebalulekile yenqubo yokukhiqiza izigxobo zokukhanya zasemgwaqweni i-hot-galvanizing. I-hot-dip galvanizing, eyaziwa nangokuthi i-hot-dip galvanizing kanye ne-hot-dip galvanizing, iyindlela ephumelelayo yokulwa nokugqwala kwensimbi futhi isetshenziswa kakhulu emishinini yokwakha yensimbi ezimbonini ezahlukahlukene. Ngemva kokuba imishini isihlanze ukugqwala, ifakwa engxubeni ye-zinc encibilikisiwe cishe ku-500°C, bese ungqimba lwe-zinc lunamathela ebusweni bengxenye yensimbi, ngaleyo ndlela kuvinjelwe insimbi ukuthi ingagqwali.
Isikhathi sokulwa nokugqwala sokucwilisa ngokushisa side kakhulu, kodwa ukusebenza kokulwa nokugqwala kuhlobene kakhulu nendawo lapho imishini isetshenziswa khona. Isikhathi sokulwa nokugqwala semishini ezindaweni ezahlukene naso sihlukile: izindawo zezimboni ezisindayo zingcoliswa kakhulu iminyaka eyi-13, izilwandle ngokuvamile ziyiminyaka engama-50 yokugqwala kwamanzi olwandle, Izindawo ezingaphansi komhlaba zingaba yiminyaka eyi-104, kanti amadolobha ngokuvamile aneminyaka engama-30.
Ukuze kuqinisekiswe ikhwalithi, ukuthembeka kanye nokuqina kwezinsika zokukhanya zasemgwaqweni zelanga, insimbi ekhethiwe ikakhulukazi yinsimbi ye-Q235. Ukuqina okuhle kanye nokuqina kwensimbi ye-Q235 kungcono kakhulu ezidingweni zokukhiqizwa kwezinsika zokukhanya. Nakuba insimbi ye-Q235 inokuqina okuhle kanye nokuqina, isadinga ukuphathwa ngokwelashwa kokulwa nokugqwala okufakwe nge-hot-dip kanye ne-plastic-sprayed. Insika yokukhanya yasemgwaqweni ehlanganisiwe inokumelana okuhle nokugqwala, akulula ukuyigqwala, futhi impilo yayo yenkonzo ingafinyelela eminyakeni eyi-15. I-hot-dip galvanized spray ifutha ngokulinganayo i-plastic powder esigxotsheni sokukhanya, futhi inamathisele ngokulinganayo i-plastic powder esigxotsheni sokukhanya ekushiseni okuphezulu ukuqinisekisa ukuthi umbala wensika yokukhanya ngeke uphele isikhathi eside.
Ubuso beisibani somgwaqo esihlanganisiweikhanya futhi iyinhle, futhi inomsebenzi wokuhlanganisa ungqimba lwensimbi i-Q235 kanye ne-zinc alloy ngokuqinile, futhi ikhombisa ukumelana okuhlukile kokugqwala, ukulwa nokugqwala kanye nokumelana nokuguguleka emoyeni wokufutha usawoti wasolwandle kanye nomoya wezimboni. I-Zinc iyaguquguquka, futhi ungqimba lwayo lwe-alloy lunamathela ngokuqinile emzimbeni wensimbi, ngakho-ke izigxobo zokukhanya zasemgwaqweni ezihlanganisiwe zingabhajwa kubanda, zigoqwe, zidonswe, zigotshwe, njll. ngaphandle kokulimaza ungqimba. Isibani sasemgwaqweni esihlanganisiwe sinongqimba oluncane noluqinile lwe-zinc oxide ebusweni bongqimba lwe-zinc, okunzima ukuncibilika emanzini. Ngakho-ke, ngisho nasezinsukwini zemvula, ungqimba lwe-zinc lunomphumela othile wokuvikela esibanini sasemgwaqweni, okwandisa isikhathi sokuphila kwesibani sasemgwaqweni.
Uma unesifiso sokuthola isibani somgwaqo esenziwe nge-galvanized, wamukelekile ukuxhumana nathiifektri yezibani zomgwaqo ezihlanganisiweTIANXIANG kuFunda kabanzi.
