Ndeupi musiyano uripo pakati pechrome plating, nickel plating, uye zinc plating?

Chii chinonzi electroplating?
Electroplating inzira yekushandisa musimboti we electrolysis kuisa chidimbu chitete chemamwe masimbi kana alloys pane mamwe masimbi. Inzira inoshandisa electrolysis kubatanidza firimu resimbi pamusoro pesimbi kana zvimwe zvinhu, nokudaro kudzivirira simbi oxidation (yakadai se ngura), kunatsiridza kusapfeka, conductivity, reflectivity, corrosion resistance (yakadai semhangura sulfate), uye kuwedzera aesthetics.
Electroplating inopatsanurwa kuita mamwe maitiro akadai semhangura plating, goridhe plating, sirivheri plating, chromium plating, nickel plating, uye zinc plating. Muindasitiri yekugadzira, zinc plating, nickel plating, uye chromium plating inonyanya kushandiswa zvakanyanya. Ndeupi musiyano uripo pakati pevatatu ava?
01- Galvanization
Tsanangudzo: Zinc plating inoreva nzira yekurapa pamusoro inosanganisira kupfekedza zingi pamusoro pesimbi, alloy, kana zvimwe zvinhu zvekunakisa nekudzivirira ngura.
Zvimiro: Mutengo wakaderera, avhareji yekudzivirira corrosion, sirivha chena ruvara.
Chishandiso: Screws, macircuit breakers, zvigadzirwa zvemaindasitiri, nezvimwe.
02- Nickel plating
Tsanangudzo: Nzira yekuisa chidimbu chenickel pasimbi kana zvimwe zvisiri-simbi kuburikidza ne electrolysis kana kemikari nzira inonzi nickel plating.
Zvimiro: Yakanaka, inogona kushandiswa pakushongedza, mutengo wepamusoro, hunyanzvi hwakaoma, uye ruvara rwesirivha chena uye yero.
Chishandiso: Mabatiro emwenje ekuchengetedza magetsi, mari, zvinhu zvehardware, nezvimwe.
03- Chromium plating
Tsanangudzo: Chromium isimbi chena inopenya ine ruvara rwebhuruu zvishoma. Nzira yekuisa chidimbu chechromium pasimbi kana zvimwe zvisiri-simbi kuburikidza ne electrolysis kana kemikari nzira inonzi chromium plating.
Zvimiro: Kune marudzi maviri echrome plating. Yokutanga ndeyezvinangwa zvekushongedza, nechitarisiko chakajeka uye chakanaka kupfeka kuramba. Kugona kwayo kudzivirira ngura haina kunaka seye zinc plating, asi iri nani pane oxidation; Nzira yechipiri ndeyekuwedzera kuoma uye kupfeka kusagadzikana kwezvikamu zvesimbi, iyo inoshanda yezvikamu.
Chishandiso: Zvikamu zvekushongedza zvinopenya, zvishandiso, faucets, nezvimwe pamidziyo yemumba, zvemagetsi uye zvimwe zvigadzirwa.
Wedzera ruzivo:
1. Electroplating kugadzirwa kunonyanya kukonzerwa neheavy metal kusvibiswa mutsvina uye tsvina. Nyika yakanyatso kudzora kuwedzera kweindasitiri yemagetsi uye yave ichideredza gore negore.
MuChina, electroplating processing inonyanya kusanganisira galvanization, copper plating, nickel plating, uye chromium plating, ine galvanization accounting ye50% uye copper plating, chromium plating, uye nickel plating accounting ye30%.
Kana chinangwa chiri chekudzivirira ngura, galvanizing kana cadmium plating inogona kushandiswa; Kana chinangwa chiri pakudzivirira kusapfeka, nickel kana chromium plating ndiyo yakanakisa sarudzo.
