Ingabe izinsika zomgwaqo zelanga kufanele zifakwe i-galvanized ebandayo noma zifakwe i-galvanized eshisayo?

Kulezi zinsuku, amakhoyili ensimbi e-Q235 asezingeni eliphezulu ayizinto ezithandwa kakhuluizinsika zomgwaqo zelangaNgenxa yokuthi izibani zasemgwaqweni zelanga zibhekana nomoya, ilanga nemvula, isikhathi sazo sokuphila isikhathi eside sincike ekhonweni lazo lokumelana nokugqwala. Insimbi ivame ukugaywa ukuze kuthuthukiswe lokhu.

Kunezinhlobo ezimbili ze-zinc plating: i-hot-dip kanye ne-cold-dip galvanizing.izinsika zensimbi ezifakwe ngogesi ezishisayoZimelana kakhulu nokugqwala, sivame ukweluleka ukuthi uzithenge. Yimuphi umehluko phakathi kwe-hot-dip kanye ne-cold-dip galvanizing, futhi kungani izingongolo ze-hot-dip galvanizing zinokumelana nokugqwala okuphezulu? Ake sibheke i-Tianxiang, ifektri edumile yaseShayina yezingongolo zasemgwaqweni.

1) Ukuhlanza Okubandayo (Okubizwa nangokuthi i-electro-galvanizing): Ngemva kokususa amafutha nokuwagaya, insimbi ifakwa esixazululweni sikasawoti we-zinc. Isixazululo sixhunywe ku-electrode engemihle yemishini ye-electrolysis, bese kubekwa ipuleti le-zinc eliphambene, elixhunywe ku-electrode engemihle. Lapho amandla evuliwe, njengoba ugesi uhamba ngokuqondile usuka ku-electrode engemihle uye ku-electrode engemihle, kwakheka ungqimba lwediphozithi ye-zinc olufana, oluqinile, noluboshwe kahle ebusweni bepayipi lensimbi.

2) Ukushisa nge-galvanizing: Ubuso bensimbi bucwiliswa ku-zinc encibilikisiwe ngemva kokuhlanza nokusebenza. Ingqimba ye-zinc yensimbi ikhula phezu kobuso bensimbi ngenxa yokusabela kwe-physicochemical phakathi kwensimbi ne-zinc endaweni ehlanganayo. Uma kuqhathaniswa nokushisa nge-galvanizing, le ndlela ikhiqiza isibopho esiqinile phakathi kokugqoka kanye ne-substrate, ithuthukisa ubuningi be-coating, ukuqina, ukusebenza ngaphandle kokugcinwa, kanye nokusebenza kahle kwezindleko.

1) Indlela Yokucubungula: Amagama abo enza umehluko ucace. I-Zinc etholakala ekushiseni kwegumbi isetshenziswa emapayipini ensimbi afakwe insimbi ebandayo, kanti i-zinc etholakala ku-450°C kuya ku-480°C isetshenziswa ekufakweni kwe-hot-dip galvanizing.

2) Ubukhulu Bokumboza: Nakuba ukumboza nge-cold-dip kuvame ukukhiqiza ubukhulu bokumboza obungu-3–5 μm kuphela, okwenza ukucubungula kube lula kakhulu, kunokumelana nokugqwala okubi. Ngokuphambene nalokho, ukumboza nge-hot-dip kuvame ukunikeza ubukhulu bokumboza obungu-10μm noma ngaphezulu, okuphindwe kaningi ukumelana nokugqwala kunezigxobo zokukhanya ze-galvanized ezimboza nge-cold-dip.

3) Isakhiwo Sokumboza: Ukumboza kanye ne-substrate kuhlukaniswa ungqimba lwe-compound oluqhekeka ngokuqhathaniswa ekubhodleni okushisayo. Kodwa-ke, ngenxa yokuthi ukumboza kwenziwe nge-zinc ngokuphelele, okuholela ekumbozeni okufanayo okunezimbobo ezimbalwa, okwenza kungabi lula ukubhodla, lokhu akunamthelela omkhulu ekumelaneni kwayo nokubhodla. Ngokuphambene nalokho, ukumboza okubandayo kusebenzisa ukumboza okwenziwe ngama-athomu e-zinc kanye nenqubo yokunamathela ngokomzimba enezimbobo eziningi, okwenza kube lula ukubhodla endaweni ezungezile.

4) Umehluko Wentengo: Ukukhiqizwa kwe-hot-dip galvanizing kunzima kakhulu futhi kuyinkimbinkimbi. Ngakho-ke, izinkampani ezincane ezinemishini emidala zivame ukusebenzisa i-cold-dip galvanizing, okuholela ezindleleni eziphansi kakhulu. Abakhiqizi be-hot-dip galvanizing abakhulu nabasunguliwe ngokuvamile banokulawula okungcono kwekhwalithi, okuholela ezindleleni eziphakeme.

Abanye abantu bangase bathi noma ngabe bayazi umehluko phakathi kokusebenzisa i-cold-dip galvanizing kanye ne-hot-dip galvanizing, abakakwazi ukubona umehluko. Lezi izindlela zokucubungula ezingabonakali ngeso lenyama. Kuthiwani uma umthengisi ongenalo iqiniso esebenzisa i-cold-dip galvanizing esikhundleni se-hot-dip galvanizing? Empeleni, asikho isidingo sokukhathazeka. Ukusebenzisa i-cold-dip galvanizing kanyeukucwilisa okushisayoKulula kakhulu ukuhlukanisa.

Izindawo ezifakwe i-cold-dip zibushelelezi, ikakhulukazi ziphuzi-luhlaza, kodwa ezinye zingase zibe nokucwebezela okukhanyayo, okumhlophe-blu, noma okumhlophe okunombala oluhlaza okotshani. Zingase zibonakale zifiphele noma zingcolile. Izindawo ezifakwe i-hot-dip galvanized, uma ziqhathaniswa, ziqinile kancane, futhi zingase zibe ne-zinc bloom, kodwa zibukeka zikhanya kakhulu futhi ngokuvamile zimhlophe-siliva. Naka lokhu kungafani.
