Cholinga cha ozizira galvanizing ndi otentha galvanizing wamizati ya nyale ya dzuwandikuletsa dzimbiri ndikutalikitsa moyo wautumiki wa nyali zamsewu za dzuwa, ndiye pali kusiyana kotani pakati pa ziwirizi?
1. Maonekedwe
Maonekedwe a galvanizing ozizira ndi osalala komanso owala.The electroplating wosanjikiza ndi mtundu passivation ndondomeko makamaka chikasu ndi wobiriwira, ndi mitundu isanu ndi iwiri.Electroplating wosanjikiza wokhala ndi njira yoyera yodutsamo ndi yoyera yoyera, komanso yowoneka bwino pang'ono pang'ono ya kuwala kwa dzuwa.N'zosavuta kupanga "kuwotcha magetsi" pamakona ndi m'mphepete mwa ndodo yovuta, zomwe zimapangitsa kuti zinki pa gawo ili likhale lolimba.N'zosavuta kupanga panopa pa ngodya yamkati ndi kupanga pansi-panopa imvi dera, zomwe zimapangitsa nthaka wosanjikiza m'dera lino woonda.Ndodoyo idzakhala yopanda zinc mtanda ndi agglomeration.
Maonekedwe a galvanizing otentha ndi ovuta pang'ono kusiyana ndi ozizira galvanizing, ndipo ndi silvery woyera.Maonekedwe ndi osavuta kutulutsa zizindikiro za madzi ndi madontho ochepa, makamaka kumapeto kwa ndodo.
Zinc wosanjikiza wa galvanizing wotentha pang'ono amakhala wokhuthala kambirimbiri kuposa kuzirala kozizira, ndipo kukana kwake kwa dzimbiri kumakhalanso kambirimbiri kuposa kutulutsa magetsi, ndipo mtengo wake mwachilengedwe ndi wokwera kwambiri kuposa wa malata ozizira.Komabe, m'kupita kwa nthawi, kutentha kwa galvanizing ndi kupewa dzimbiri kwa zaka zoposa 10 kudzakhala kodziwika kwambiri kuposa kuzizira kozizira ndi kupewa dzimbiri kwa zaka 1-2 zokha.
2. Njira
Cold galvanizing, amatchedwanso galvanization, ndi kugwiritsa ntchito zipangizo electrolytic kuika ndodo mu njira munali nthaka mchere pambuyo degreasing ndi pickling, ndi kulumikiza mzati zoipa za zipangizo electrolytic.Ikani mbale ya zinc mbali ina ya ndodo kuti mulumikizane ndi zida za electrolytic, ndikulumikizani magetsi, ndipo gwiritsani ntchito njira yoyendetsera zomwe zili mu mtengo wake kuti musungitse zinc pa workpiece;Hot galvanizing ndi kuchotsa mafuta, asidi kusamba, kuviika mankhwala ndi kuumitsa workpiece, ndiyeno kuviika mu njira yosungunuka zinki kwa nthawi inayake, ndiyeno kuchotsa izo.
3. Chophimba chophimba
Pali wosanjikiza wa brittle pawiri pakati ❖ kuyanika ndi gawo lapansi la galvanizing otentha, koma alibe mphamvu yaikulu kukana dzimbiri, chifukwa ❖ kuyanika kwake ndi koyera zinki ❖ kuyanika, ndi ❖ kuyanika ndi yunifolomu, popanda pores, ndipo si. zosavuta zimbiri;Komabe, ❖ kuyanika ozizira galvanizing wapangidwa ena maatomu nthaka, amene ali thupi adhesion.Pali pores ambiri pamwamba, ndipo n'zosavuta kukhudzidwa ndi chilengedwe ndi dzimbiri.
4. Kusiyana pakati pa ziwirizi
Kuchokera pa mayina a awiriwa, tiyenera kudziwa kusiyana kwake.Zinki mu mipope ozizira kanasonkhezereka zitsulo analandira kutentha firiji, pamene nthaka galvanizing otentha ndi analandira pa 450 ℃ ~ 480 ℃.
5. Kupaka makulidwe
Kukhuthala kwa zokutira zoziziritsa kuzizira nthawi zambiri kumakhala 3 ~ 5 μ m.Ndikosavuta kukonza, koma kukana kwake kwa dzimbiri sikwabwino kwambiri;Chophimba chotenthetsera chovimbidwa nthawi zambiri chimakhala ndi 10 μ Kukana kwa dzimbiri kwa makulidwe a m ndi pamwamba ndikwabwinoko, komwe kumakhala pafupifupi kangapo kuposa pamtengo woziziritsa.
6. Kusiyana kwamitengo
Kutentha kotentha kumakhala kovuta kwambiri komanso kovutirapo pakupanga, kotero mabizinesi ena okhala ndi zida zakale komanso zazing'ono nthawi zambiri amatengera njira yoziziritsa popanga, yomwe imakhala yotsika mtengo komanso mtengo wake;Komabe,otentha-kuviika galvanizing opanganthawi zambiri amakhala okhazikika komanso okulirapo.Iwo ali ndi ulamuliro wabwino pa khalidwe ndi mtengo wapamwamba.
Kusiyana komwe kuli pamwambapo pakati pa galvanizing otentha ndi ozizira galvanizing mizati dzuwa msewu nyale akugawidwa pano.Ngati mizati ya nyali ya dzuwa iyenera kugwiritsidwa ntchito m'madera a m'mphepete mwa nyanja, ayenera kuganizira za kukana kwa mphepo ndi kukana kwa dzimbiri, ndipo musapange ntchito ya zinyalala chifukwa cha umbombo wanthawi yochepa.
