Ubuchule bonyango lomphezulu obubandakanya ukwaleka umaleko we-zinc kumphezulu wezinto ezixutywe nentsimbi ngeenjongo zobuhle kunye nokuthintela umhlwa. I-zinc layer phezu komhlaba ngumaleko okhuselayo we-electrochemical onokuthintela ukubola kwesinyithi. Iindlela eziphambili ezisetyenziswayo yi-hot dip galvanizing kunye ne-electro galvanizing.
Imathiriyeli esebenzayo:
Ngenxa yokuxhomekeka kwenkqubo ye-galvanizing kwi-teknoloji ye-metallurgical bonding, ifanelekile kuphela kunyango oluphezulu lwentsimbi kunye nentsimbi.
Iindleko zenkqubo: Akukho xabiso lokungunda, umjikelo omfutshane /ixabiso eliphakathi labasebenzi, njengoko umgangatho womphezulu we-workpiece ubukhulu becala uxhomekeke kunyango lomphezulu owenziwe ngesandla phambi kokugalela.
Impembelelo yokusingqongileyo: Ngenxa yenkqubo ye-galvanized yokwandisa ubomi benkonzo yeentsimbi ze-40-100 iminyaka, ikhusela ngokufanelekileyo ukugqwala kunye nokubola kwe-workpiece, ngaloo ndlela ibe nefuthe elihle ekukhuseleni indalo. Ukongeza, ii-workpieces ze-galvanized zingabuyiselwa kwi-tank ye-galvanizing emva kokuba ubomi babo benkonzo buphelile, kwaye ukusetyenziswa ngokuphindaphindiweyo kwe-zinc engamanzi akuyi kuvelisa inkunkuma yekhemikhali okanye yomzimba.
Inkqubo yokusebenzisa i-electrolysis ukuncamathisela umaleko wefilimu yesinyithi kumphezulu wenxalenye, ngaloo ndlela ikhusela i-oxidation yesinyithi, iphucula ukumelana nokunxiba, ukuhanjiswa, ukubonakalisa, ukuxhathisa ukubola, kunye nokuphucula i-aesthetics. Iingqekembe ezininzi nazo zinemigangatho yazo yangaphandle i-electroplated.
Imathiriyeli esebenzayo:
1. Uninzi lwesinyithi lunokuthi lufakwe kwi-electroplated, kodwa isinyithi esihlukeneyo sinemigangatho eyahlukeneyo yobunyulu kunye nokusebenza kakuhle kwe-electroplating. Ezona zixhaphakileyo yitin, ichromium, nickel, isilivere, igolide, kunye nerhodium.
Iplastiki esetyenziswa kakhulu kwi-electroplating yi-ABS.
3. Isinyithi se-nickel akufanele sisetyenziswe kwiimveliso ze-electroplating ezidibana nolusu, njengoko i-nickel iyacaphukisa kwaye inetyhefu eluswini.
Iindleko zenkqubo: Akukho ndleko yokubumba, kodwa ukulungiswa kuyafuneka ukulungisa iindawo. Iindleko zexesha zixhomekeke kwiqondo lokushisa kunye nohlobo lwetsimbi / iindleko zabasebenzi (eziphakathi phezulu), kuxhomekeke kuhlobo oluthile lwamacandelo e-electroplated. Ngokomzekelo, i-electroplating yesilivere kunye nobucwebe ifuna abasebenzi abanezakhono eziphezulu ukuba basebenze, njengoko kufuna iimfuno eziphezulu zokubonakala kunye nokuqina.
Impembelelo yokusingqongileyo: Isixa esikhulu sezinto ezinobuthi ziya kusetyenziswa kwinkqubo ye-electroplating, ngoko ke ukuphambuka kobuchwephesha kunye nokukhutshwa kuyafuneka ukuze kuqinisekiswe impembelelo encinci yokusingqongileyo.
