Ukugqwala noma ukuguquguquka kwemibalaucingo lwensimbiemkhathini obangelwa umoya-mpilo, umswakama nokunye ukungcola okungcolile kubizwa ngokuthi ukugqwala noma ukugqwala.Ngemuva kokugqwala kwensimbi yensimbi, kuzothinta ikhwalithi yokubukeka, kuthinte kabi ukusetshenziswa, futhi kubangele nezicucu, ngakho-ke ucingo lwensimbi oluvunyiwe kufanele lugcinwe kahle futhi lunake ukuvimbela ukugqwala.
Ukunamathela kweZinc kuvuliweucingo lukathayelaubuso nobukhulu be-zinc layer
A. Uma ubukhulu be-plating bungu-3-4 mm, ukunamathela kwe-zinc kufanele kube ngaphansi kuka-460g/m, okungukuthi, ubukhulu obujwayelekile bongqimba lwe-zinc abukho ngaphansi kwama-microns angu-65.
B. Uma ubukhulu be-plating bukhulu kuno-4 mm, ukunamathela kwe-zinc akufanele kube ngaphansi kuka-610g/m, okungukuthi, ubukhulu obuphakathi kwesendlalelo se-zinc akufanele kube ngaphansi kwama-microns angu-86.
C, ukufana kwe-coating: ungqimba lukathayela lufana ngokuyisisekelo nokuhlolwa kwesisombululo se-copper sulfate esiqoshwe izikhathi ezinhlanu ngaphandle kokudalula insimbi.
D, ukunamathela kokunamathela;Isendlalelo se-zinc sezingxenye zokucwenga kufanele sihlanganiswe ngokuqinile nesisekelo sensimbi esinamandla okwanele okunamathela, futhi ngeke siwe noma siqhume ngemva kokuhlolwa kwesando.
