1. Electroplating process control
Mamiriro ebasa uye hupenyu hwebasa regalvanized iron wirekana zvikamu zvakabatana zvakanyanya nehupamhi hwejasi.Kunyanya kuomarara kwemamiriro ekushandisa uye kureba kwehupenyu hwesevhisi, kukora kunodiwa kwewaya yesimbi kunofanirwa kuve.Zvigadzirwa zvakasiyana, zvinoenderana nemamiriro ekunze (tembiricha, humidity, kunaya kwemvura, kuumbwa kwemuchadenga, nezvimwewo) kuona hupenyu hunotarisirwa hwesevhisi yehukobvu hwekufukidzira, kukora kwemapofu kunokonzeresa marudzi ese emarara.Asi kana ukobvu husina kukwana, haungasviki pane zvinotarisirwa zvehupenyu hwesevhisi zvinodiwa.Vagadziri vakasiyana, zvinoenderana nemamiriro avo emidziyo, kana iri yekutarisa plating, yekutanga gadziriro yekuyerera kwakazara uye inonzwisisika kuyerera, yakajeka plating paramita, kudzora plating mhinduro yekuisa, yakajairwa kushanda.
2, inopisa plating waya plating mushure mekugadzirisa
Post-plating kurapwa (passivation, kupisa kunyunguduka, kuvhara uye kubvisa hydrogen, nezvimwewo) nechinangwa chekusimudzira zvinhu zvekudzivirira, kushongedza uye zvimwe zvinangwa zvakakosha.Mushure mekuputika, chromate passivation kana kumwe kutendeuka kurapwa kunowanzo kudikanwa kuti ugadzire inoenderana mhando yekushandura firimu, inova imwe yeakakosha maitiro ekuona kunaka kwepost-plating.
3, galvanized waya galvanized process
Kune zvakakosha uye zvakakosha zvikamu zvine simba rekusimba rakakura kupfuura 1034Mpa, kushushikana kunofanirwa kubviswa pa200±10 ℃ kweawa inodarika 1 isati yaputirwa, uye kune carburized kana nzvimbo dzakaomeswa, kushushikana kunofanirwa kubviswa pa140±10 ℃ kune zvimwe. kupfuura maawa mashanu.Iyo yekuchenesa inoshandiswa pakuchenesa haizove nemhedzisiro pane inosunga simba rejasi uye hapana corrosion pane substrate.Acid activation Acid activation solution inofanira kukwanisa kubvisa corrosion products uye oxide film (ganda) pamusoro pezvikamu pasina kuora kwakanyanyisa pamatrix.
Galvanizing inogona kuitwa ne zincate galvanizing kana chloride galvanizing.Zvinowedzerwa zvakakodzera zvinofanirwa kushandiswa kuwana jasi rinosangana nezvinodiwa nechiyero ichi.Kurapa kwechiedza kunofanira kuitwa mushure mekuisa chiedza.Zvikamu zvinoda kubviswa dehydrogenated kuitira passivation zvinofanirwa kupfuudzwa mushure me dehydrogenation.Pasati papfuura, 1% H2SO4 kana 1% hydrochloric acid inofanira kuiswa kuti ishandiswe kwe5 ~ 15s.Passivation ichabatwa neruvara chromate kunze kwekunge yatsanangurwa neimwe nzira mudhizaini yedhizaini.
Kushandiswa kwakafara kwewaya yemarara kwakaunza kurerukirwa kukuru mukugadzirwa kwevanhu nehupenyu, asi nzira yekugadzira waya yesimbi haifanirwe kurerutswa.Mukugadzirwa kwemaindasitiri, maitiro ekugadzira waya ane galvanized anofanira kunyatsodzorwa kuti ave nechokwadi chemhando yewaya.
