Kupisa dip galvanizing yesimbi ndiro inonziwo hot dip galvanizing.Zinc ingots inonyungudutswa munzvimbo dzinopisa uye zvimwe zvekubatsira zvinowedzerwa mukupisa dip galvanizing.Nhengo dzegridi dzesimbi dzinobva dzanyudzwa mutangi rinoita kuti galvanizing layer isungirwe pandiro yesimbi.Kusimba kwekupisa dip galvanizing kunoenderana nekushomeka kwayo, uye kunamatira uye kuomarara kwepepa rine galvanized zviri nani.Huwandu hwendiro yesimbi yakabatiswa mushure mekuvheneka.Saka iyi ndiyo yakawanda yakawanda ye zinc.
Kuumbwa kweiyo inopisa dip galvanizing layer inoumbwa nekupisa dip galvanizing layer, iyo inoumbwa nesimbi zinc alloy pakati pesimbi matrix uye pamusoro yakachena zinc layer.Chimiro cheworkpiece chinoumbwa nesimbi zinc alloy layer mune inopisa dip, kuitira kuti simbi uye yakachena zinc layer inobata zvakatanhamara.Kana iyo iron workpiece yakanyudzwa mune yakanyungudutswa zinc mhinduro, iyo yekutanga zinc nesimbi (muviri) inoumbwa pane iyo interface.Iyi ikristaro yakaumbwa nemaatomu ezinc musimbi yakasimba.Kana maatomu maviri esimbi abatanidzwa pamwe chete, simba regiravhiti riri pakati peatomu rinenge diki.
Nokudaro, kana zingi yakwana mukunyunguduka kwakasimba, maatomu maviri ezingi nesimbi anoparadzana.Maatomu ezinc ari musimbi matrix anofambiswa mulatisi yematrix, uye zvinhu zvesimbi zvinoumbwa zvishoma nezvishoma kuita alloys.Iyo zinc inoumbwa nesimbi uye intermetallic musanganiswa FeZn13 mune yakanyungudutswa zinc mhinduro uye pasi pe inopisa galvanized sheet inogona kushandiswa se zinc slag.Iyo yakachena zinc layer inoumbwa ne zinc leaching solution ndeye hexagonal crystal.
Kana tembiricha iri kushanda patembiricha imwechete uye kupisa kwakafanana kunochengetwa, huwandu hwesimbi yakanyungudutswa haina kufanana.Panenge pa500, kurasikirwa kwesimbi kunowedzera zvakanyanya nekuwedzera kwekushisa uye kuvhara.Iyo yakaderera kana yakakwirira kupfuura 480 ~ 510c, uye kurasikirwa kwe epitaxial iron kunonoka, uye zvakaoma kubata nenguva.Naizvozvo, munhu wese achadaidza 480 ~ 510c iyo yakaipa yekunyungudika nzvimbo.
Mune ino tembiricha renji, iyo zinc mhinduro yakasvibiswa zvakanyanya kune workpiece uye zingi poto, uye simbi inorasika pa560 madhigirii Celsius kuwedzera zviri pachena, uye zingi ichava simbi substrate inopfuura 660 degrees Celsius, zinc slag ichawedzerwa. nekukurumidza, plating haigone kushandiswa.Nokudaro, electroplating inoitwa muhuwandu hwe430 ~ 450 degrees Celsius.
