Iyo electroplating processinzira yekuputira kondakita nesimbi yesimbi uchishandisa musimboti we electrolysis.Electroplating inoreva nzira yekugadzira pamusoro apo simbi yepasi ichaputirwa inoshandiswa se cathode mune munyu munyu une simbi yakagara yakanamirwa, uye macations esimbi yakagara yakanamirwa mumushonga weplating anoiswa pamusoro pemvura. hwaro simbi kuburikidza electrolysis kuumba unhani.
Zvinhu zvekuputira zvakasiyana kubva kune zvesimbi yepasi uye zvine maitiro matsva.Maererano nebasa rekuvhara, rakakamurwa kuva chidziviriro chekudzivirira, chifukidzo chekushongedza uye mamwe maitiro anoshanda.
Munguva ye electroplating, simbi yakanyungudutswa kana zvimwe zvisinganyunguriki zvinoshandiswa seanode, iyo workpiece inofanira kuiswa inoshandiswa se cathode, uye cations yesimbi yakaputirwa inoderedzwa pamusoro pebasa rekushanda kuti riputirwe kuti rive rakaputirwa. .Inogona kukwidziridza kusimba kwesimbi yesimbi (iyo yekubikira simbi inowanzoita ngura-inodzivirira simbi), kuwedzera kuomarara, kudzivirira kupera, kunatsiridza conductivity, kutsvedzerera, kupisa kupisa uye kunaka kwepasi.
Fundamental
Electroplatinginonzi electrochemical process pamwe chete neredox process.Iyo yakakosha maitiro e electroplating ndeyekunyudza chikamu mumhinduro yesimbi munyu se cathode, ndiro yesimbi seanode,amushure mekunge simba reDC ravhurwa, iyo yaidiwa coating inoiswa pane chikamu.
CraftingProcess
Kazhinji, inosanganisira matanho matatu e pre-plating pretreatment, electroplating uye post-plating kurapwa.
Kuzadza maitiro: 1. Kunhonga → yakazara ndiro electroplating
Mhangura → kuchinjisa patani → kucheneruka kweasidhi → kugezesa kwechipiri → kucheneruka zvishoma → yechipiri → kunhonga → kunyura → tin kupfava → kugezeswa kwechipiri, kusukurudza kwechipiri → pickling → peteni yemhangura → kugezesa kwechipiri → nickel plating → Level 2 washing citric acid → kuisa goridhe → kudzokorodza → mwero 2-3 kugeza mvura yakachena → kuomesa.
