Unyango lomphezulu wezinto ezixutyiweyo: i-chrome plating, i-nickel plating, i-zinc plating, yintoni umahluko?

Xa kufikwa kwi-electroplating, kufuneka siqale siqonde ukuba yintoni kanye kanye. Ngamafutshane, i-electroplating yinkqubo yokusebenzisa umgaqo we-electrolysis ukufaka umaleko omncinci wezinye izinyithi okanye ii-alloys kumphezulu wesinyithi.

Oku akungenxa yembonakalo, kodwa okubaluleke ngakumbi, kunokuthintela i-oxidation kunye nokugqwala, ngelixa kuphucula ukumelana nokuguguleka komphezulu, ukuhanjiswa komoya, kunye nokumelana nokugqwala. Kakade ke, imbonakalo inokuphuculwa.

Kukho iintlobo ezininzi ze-electroplating, kuquka i-copper plating, i-gold plating, i-silver plating, i-chrome plating, i-nickel plating, kunye ne-zinc plating. Kwishishini lokuvelisa, i-zinc plating, i-nickel plating, kunye ne-chrome plating zisetyenziswa kakhulu. Yintoni umahluko phakathi kwazo zontathu? Makhe sijonge nganye nganye.

Isigqubuthelo seZinc

Ukugquma i-zinc yinkqubo yokugquma umaleko we-zinc kumphezulu wesinyithi okanye ezinye izinto, ikakhulu ngenjongo yokuthintela ukugqwala kunye neenjongo zobuhle.

Iimpawu zazo zixabiso eliphantsi, ukumelana nokugqwala okufanelekileyo, kunye nombala omhlophe wesilivere.

Isetyenziswa kakhulu kwizinto ezithintela iindleko nezimelana nomhlwa ezifana nezikrufu, iziqhekezi zesekethe, kunye neemveliso zoshishino.

Isigqubuthelo seNickel

I-Nickel plating yinkqubo yokufaka umaleko we-nickel phezu komhlaba ngokusebenzisa i-electrolysis okanye iindlela zeekhemikhali.

Iimpawu zayo kukuba inenkangeleko entle, ingasetyenziselwa ukuhombisa, ubuchule bayo buyinkimbinkimbi kancinci, ixabiso layo liphezulu, kwaye umbala wayo umhlophe wesilivere kunye nencasa etyheli.

Uza kuyibona kwiintloko zezibane ezonga umbane, iingqekembe, kunye nezinye izixhobo.

Isigqubuthelo se-Chrome

I-Chrome plating yinkqubo yokufaka umaleko we-chromium phezu komphezulu. I-Chrome ngokwayo yintsimbi emhlophe eqaqambileyo enencasa yeblue.

I-Chrome plating yahlulwe kakhulu yaba ziintlobo ezimbini: enye ihombisa, inembonakalo eqaqambileyo, iyamelana nokuguguleka, kwaye ithintela ukugqwala imbi kancinci kune-zinc plating kodwa ingcono kune-oxidation eqhelekileyo; Enye iyasebenza, ngenjongo yokwandisa ubulukhuni kunye nokumelana nokuguguleka kwamalungu.

Imihombiso ekhazimlayo kwizixhobo zasekhaya nakwiimveliso ze-elektroniki, kunye nezixhobo kunye neempompo, zihlala zisebenzisa i-chrome plating.

Umahluko osisiseko phakathi kwaba bathathu

I-Chrome plating isetyenziselwa ikakhulu ukwandisa ubulukhuni, ubuhle, kunye nokuthintela umhlwa. Iipropati zeekhemikhali zomaleko we-chromium zizinzile kwaye azisabela kwi-alkali, i-nitric acid, kunye ne-organic acids ezininzi, kodwa zinovelwano kwi-hydrochloric acid kunye ne-sulfuric acid eshushu. Ayitshintshi umbala, inamandla okubonakalisa ixesha elide, kwaye inamandla kunesilivere kunye ne-nickel. Inkqubo idla ngokuba yi-electroplating.

I-Nickel plating igxile ekumelaneni nokuguguleka, ukumelana nokugqwala, kunye nokuthintela ukugqwala, kwaye i-coating ngokubanzi incinci. Kukho iintlobo ezimbini zeenkqubo: i-electroplating kunye ne-chemistry.

Ngoko ke ukuba uhlahlo lwabiwo-mali alukho semgangathweni, ukukhetha i-zinc plating ngokuqinisekileyo lukhetho olufanelekileyo; Ukuba ufuna ukusebenza ngcono kunye nenkangeleko, kuya kufuneka ucinge nge-nickel plating okanye i-chrome plating. Ngokufanayo, i-hanging plating idla ngokubiza kakhulu kune-rolling plating ngokwenkqubo.
