Yintoni i-electroplating?
I-Electroplating yinkqubo yokusebenzisa umgaqo we-electrolysis ukufaka umaleko obhityileyo wezinye isinyithi okanye i-alloys kwiindawo ezithile zetsimbi. Yinkqubo esebenzisa i-electrolysis ukuze ifake ifilimu yesinyithi kumphezulu wetsimbi okanye ezinye izinto eziphathekayo, ngaloo ndlela ikhusela i-oxidation yensimbi (efana ne-rust), ukuphucula ukuxhathisa ukunxiba, ukuhanjiswa, ukubonakaliswa, ukuxhathisa ukubola (njenge-sulfate yobhedu), kunye ukuphucula ubuhle.
I-Electroplating iphinda yahlulwe ngokweenkqubo ezithile ezinje ngobhedu, ukufakwa kwegolide, ukucwenga kwesilivere, ukucwenga kwechromium, ukufakwa kwe-nickel, kunye ne-zinc plating. Kwishishini lemveliso, i-zinc plating, i-nickel plating, kunye ne-chromium plating zisetyenziswa kakhulu. Yintoni umahluko phakathi kwezi zintathu?
01- Galvanization
Ingcaciso: I-zinc plating ibhekisa kubuchule bonyango obungaphezulu obubandakanya ukwaleka umaleko we-zinc kumphezulu wesinyithi, i-alloy, okanye enye imathiriyeli ngeenjongo zobuhle kunye nokuthintela umhlwa.
Iimpawu: Iindleko eziphantsi, ukuxhathisa ukubola okuphakathi, umbala omhlophe wesilivere.
Isicelo: Izikrufu, abaphuli beesekethe, iimveliso zoshishino, njl.
02-Nickel plating
Ingcaciso: Indlela yokwaleka umaleko wenikeli kwintsimbi okanye kwizinto ezingezizo iintsimbi ngokusebenzisa i-electrolysis okanye iindlela zeekhemikhali kuthiwa yi-nickel plating.
Iimpawu: Intle, inokusetyenziselwa ukuhombisa, ixabiso eliphezulu, ubugcisa obuntsonkothileyo, kunye nombala wesilivere omhlophe kunye notyheli.
Isicelo: Izibane zokugcina izibane zokulondoloza amandla, iingqekembe, izixhobo ze-hardware, njl.
03- Chromium plating
Ingcaciso: I-Chromium yintsimbi emhlophe eqaqambileyo enombala obhulowu kancinci. Indlela yokwaleka umaleko wechromium kwintsimbi okanye ezinye ezingezizo iintsimbi ngokusebenzisa i-electrolysis okanye iindlela zekhemikhali ibizwa ngokuba yichromium plating.
Iimpawu: Kukho iintlobo ezimbini ze-chrome plating. Eyokuqala yenzelwe iinjongo zokuhlobisa, kunye nenkangeleko eqaqambileyo kunye nokumelana nokunxiba kakuhle. Ikhono layo lokuthintela umhlwa alilunganga njengaleyo ye-zinc plating, kodwa ingcono kune-oxidation; Indlela yesibini kukwandisa ubunzima kunye nokuxhatshazwa kokugqoka kweengxenye zetsimbi, okuyiyo ukusebenza kwamacandelo.
Isicelo: Iindawo zokuhombisa eziqaqambileyo, izixhobo, iifaucets, njl njl kwizixhobo zendlu, i-electronics kunye nezinye iimveliso.
Yandisa ulwazi:
1. Ukuveliswa kwe-Electroplating kubangelwa ikakhulu kukungcola kwentsimbi enzima kugutyulo kunye nogutyulo. Ilizwe lilawule ngokungqongqo ukwandiswa kweshishini le-electroplating kwaye liye lanciphisa unyaka nonyaka.
E-China, ukufakwa kwe-electroplating ikakhulu kubandakanya i-galvanization, i-copper plating, i-nickel plating, kunye ne-chromium plating, kunye ne-galvanization accounting ye-50% kunye ne-copper plating, i-chromium plating, kunye ne-nickel plating accounting ye-30%.
Ukuba injongo kukuthintela umhlwa, igalvanizing okanye i-cadmium plating ingasetyenziswa; Ukuba kugxininiswa ekuthinteleni ukunxiba, i-nickel okanye i-chromium plating yeyona nto ingcono kakhulu.
