Inkampani yethu igxile ekuthumeleni ipayipi lensimbi engenamthungoipayipi likathayela, Ipayipi Elivunyiwe Elingenamthungo, Ipayipi likathayela le-SMLS, Ipayipi likathayela elishiselwe.
Uyini umehluko phakathi kwamagalvanized ashisayo namakhaza?
I-Hot-dip galvanizing kanye nokubanda kwanika amandla umehluko:
1. Galvanizing, eyaziwa nangokuthi idiphu hot lashukumisa, nguye ingot elincibilikisiwe emazingeni okushisa aphezulu, inani lempahla eyengeziwe endaweni, ke wacwiliswa lashukumisa metal isakhiwo slot, ingxenye metal on ungqimba zinc enamathela . Izinzuzo ze-hot-dip galvanizing corrosion yekhono lakhe, ukunamathela kanye nobulukhuni be-zinc coating kungcono
"Cold plated" noma "plating", okungukuthi isixazululo zinc usawoti by electrolysis, ukuze Plating on enamathela, ngokuvamile abanalo Ukushisa, inani elincane zinc, imvelo emanzi kulula kakhulu ukuwa.
2. Idiphu elishisayo lifakwe ama-galvanized (galvanizing)
I-Hot-dip galvanizing iwukwelapha ngamakhemikhali, ukusabela kwe-electrochemical.
Cold galvanizing ikheli ngokomzimba, nje ukuxubha ungqimba ebusweni zinc, ungqimba zinc kulula ukuwa off. Ukwakhiwa ekusetshenzisweni kwe-hot dip galvanizing.
Inqubo eqhubekayo yokufaka amadiphu ashisayo: insimbi → ukufudumeza → ukupholisa izinga lokushisa ngama-galvanized → ukupholisa →
I-zinc ebandayo yama-galvanized ingu-10-50g/m2 kuphela, ukumelana nokugqwala kwayo kunediphu elishisayo elipheceleza umehluko omkhulu. Kukhanyiswe ngentengo eshibhe uma kuqhathaniswa.
I-hot dip galvanized steel body iyindawo eshisayo yediphu ngaphansi kwesimo sokunamathela kwayo eqinile, akulula ukuwa, nakuba kukhona idiphu elishisayo.ipayipi likathayelaukugqwala, kodwa esikhathini eside kakhulu ukuhlangabezana nezobuchwepheshe, izidingo zezempilo.
3. Ukwehluka kwezobuchwepheshe
Okokuqala, umehluko phakathi inqubo: hot-dip galvanizing iyona workpiece degreasing, pickling, ukucwilisa, omiswe ukucwiliswa liquid in ezincibilikisiwe zinc isikhathi esithile, ingavuswa.
Eyaziwa nangokuthi i-electro-galvanized cold galvanizing, iwukusebenzisa amadivaysi e-electrolysis workpiece ngokusebenzisa i-degreasing, izithako zokukhetha okuthunyelwe kusixazululo sikasawoti zinc, futhi uxhume imishini ye-anode electrolysis; endaweni yonkana izingxenye zepuleti le-zinc elixhunywe emshinini we-electrolysis omuhle, amandla avuliwe, ukusetshenziswa kwamandla kusukela ku-cathode kuya ku-anode yokunyakaza okuqondisayo kwe-workpiece kuzofakwa ungqimba lwe-zinc.
UZinc uqede umehluko: akukho okubandayo okucwebezelayo okucwebezelayo okucwebezelayo okucwebezelayo, kodwa ukujiya kocwecwe lwezinki lwezici ezibandayo zokucwebezelisa amadiphu ashisayo izikhathi ezimbalwa. Ukumelana nokugqwala kwe-galvanized nakho kuyizikhathi eziningana.
