Mamiriro ebasa uye hupenyu hwebasa reelectrogalvanized iron wirekana chikamu chakanyatsoenderana neukobvu hwe electroplating layer.Kunyanya kuomarara kwemamiriro ekushandisa uye kureba kwehupenyu hwesevhisi hwewaya inopisa, ndiko kuwedzera kwewaya ye electrogalvanizing inodiwa.Zvigadzirwa zvakasiyana, zvinoenderana nemamiriro ekunze kuti uone hupenyu hunotarisirwa hwesevhisi ye electroplating ukobvu, kukora kwemapofu kunokonzeresa marudzi ese emarara, asi kana ukobvu husina kukwana, uye hausvike kune inotarisirwa hupenyu hwesevhisi zvinodiwa.
Vagadziri vakasiyana zvinoenderana nemamiriro avo emidziyo, kana iri yekuona rudzi rweplating, kugadzirira imwe yakazara uye inonzwisisika maitiro, yakajeka electroplating paramita, kudzora kusungwa kwe electroplating mhinduro, yakajairwa kushanda.Plating post kurapwa kwekusimudzira kuchengetedza, kushongedza uye zvimwe zvakakosha zvinangwa.Mushuregalvanizing, chromate passivation kana kumwe kutendeuka kurapwa kunowanzoitwa kuumba inoenderana mhando yekushandura firimu, inova imwe yeakakosha maitiro ekuona kunaka kweplating.
Galvanized wiregalvanizing process: stress kubviswa usati waputira uko simba rekusimba rakakura kupfuura 1034Mpa kiyi, zvakakosha zvikamu zvisati zvaiswa pa200±10 ℃ kubvisa kushushikana kweawa inopfuura 1, carburizing kana kuomeswa kwepasi kunofanira kunge kuri 140±10℃ kubvisa. kushushikana kweanopfuura maawa mashanu.Mushandi wekuchenesa anoshandiswa pakuchenesa haafaniri kuva nemigumisiro pane simba rinosungirirwa rekuputira uye pasina kuora kune matrix.Acid activation Acid activation liquid inofanira kukwanisa kubvisa zvigadzirwa zvengura pamusoro pezvikamu, oxide film (ganda), kwete pamusoro pekuora kune matrix.
Zinc plating inogona kuve zinc yakaputirwa ne zincate kana chloride, zvakakodzera zvekuwedzera zvinofanirwa kushandiswa kuwana coating inosangana nezvinodiwa zvechiyero ichi.Mushure mekuisa chiedza, kurapwa kwakareruka kunofanira kuitwa.Zvikamu zvekupfuura zvinoda kuve dehydrogenated zvinofanirwa kupfuudzwa mushure me dehydrogenation.Isati yapfuura, 1% H2SO4 kana 1% hydrochloric acid inofanira kushandiswa kwe5 ~ 15s.Passivation ichaitwa ne chromate color kunze kwekunge yatsanangurwa neimwe nzira padhizaini yedhizaini.
Kushandiswa kwakafara kwewaya yemarara kwakaunza kurerukirwa kukuru mukugadzirwa kwevanhu uye hupenyu, asi maitiro ekugadzirawaya yesimbihaifaniri kurerutswa.Mukugadzirwa kwemaindasitiri, maitiro ekugadzira waya ane galvanized anofanira kunyatsodzorwa kuti ave nechokwadi chemhando yewaya.
