Namhlanje, imalunga nokucwangciswa kwentloko yeshawari.
I-Electroplating yinkqubo yokwenza umphezulu wesinyithi unamathisele umaleko wefilimu yesinyithi nge-electrolysis.Emva kwe-electroplating, umaleko okhuselayo wenziwa kumphezulu we-substrate, ophucula ukuxhathisa ukubola kunye nokumelana nokunxiba kwishawa, kwaye iphucula imbonakalo yeglosi kunye nesidanga sobuhle.I-Electroplating inokwahlulwa ibe yi-nickel, i-chromium plating, i-zinc plating, njl njl ngokumalunga nokubunjwa kwengubo, enokuthi ibe yi-electroplating enye okanye i-multi-layer plating.
Xa abathengi bekhethaishawa, banokufumanisa ukuba umphezulu weshawari uqaqambile njengesipili, kwaye omnye umphezulu ngumzobo we-matte.Imbonakalo eyahlukileyo inxulumene nenkqubo yonyango yomphezulu ishawa. Okwangoku, unyango olungaphezulu lweshawa kwishishini lubandakanya i-electroplating, umzobo kunye nepeyinti yokubhaka, ngakumbi i-electroplating.
Siyabona ukuba isitshizi esiphezulu sihlala sikhanya njengesibuko, esisekelwe kwi-substrate yonyango lwe-electroplating.
Intloko yeshawaifakwe kwigumbi lokuhlambela.Ngenxa yokunxibelelana kwexesha elide kunye nomphunga wamanzi, ukuba i-coating ayilungile, iya kuba yi-oxidized kwaye ibole ngokukhawuleza, kwaye yonke i-coating iya kukhupha.Ichaphazela kakhulu ukusetyenziswa kwabasebenzisi.Ngoko ke, xa sikhetha ishawari, kufuneka sinikele ingqalelo ekugqumeni kweshawari.Ukwaleka okulungileyo kunokumelana ne-oxidation, ukuxhathisa ukunxiba, kwaye kuya kuqaqamba kwaye kutsha iminyaka emininzi.
Isitshizi sesilivere, ngenxa yomphezulu wenkqubo, ukuze kwandiswe ukuxhathisa umhlwa, kwaye akukho lula ukulinganisa amanzi.
Intloko yeshawa yobhedu esulungekileyo iya kwamkela i-electroplating ukuphucula ukuguda komphezulu kunye nokumelana nomhlwa.Umgangatho wesizwe ufuna ukuba iimveliso zeshawari zinokufikelela kwibakala lesi-9 loplating emva kweeyure ezingama-24 zovavanyo lokutshiza ngetyuwa.Ngokubanzi, isitshizi sobhedu siya kwamkela inkqubo yokufakwa kwe-electroplating, ekukutyalwa kobhedu ezantsi, ukucakwa kwe-nickel embindini kunye nokufakwa kwechromium kumphezulu, ubuncinci imigangatho emithathu.Kufuneka igcinwe iiyure ezingama-24 kuvavanyo lwesitshizi setyuwa.Ukuba umphezulu womhlaba ungaphantsi kwe-0.1%, uya kuthathwa njengofanelekileyo kwaye ufikelele kumgangatho weBakala 9.Okukhona uvavanyo lwesitshizi setyuwa lwenziwa ixesha elide kwimveliso ephezulu, kokukhona inqanaba elihambelanayo liphezulu.
Iishawari ezenziwe nge304 intsimbi engenasici iphathwa ngokubanzi ngomzobo womphezulu okanye i-electroplating, ekwakukonyusa ukumelana nomhlwa.
Qwalasela ukwambathisa kweeshawa ukusuka kwinkangeleko, kunye neendawo zokwaleka zeiishawa, zibandakanya isitshizi esiphezulu, isigqubuthelo sangaphambili nasemva seshawa ebanjwe ngesandla, intonga yokunyusa, itephu, intloko yebhola kwishawari ephezulu, indawo yokungena yamanzi, isigqubuthelo sokuhlobisa, njl.
1. phantsi kokukhanya kwendalo, iimveliso ze-electroplating zibekwe malunga ne-45 degrees ye-angle ebonakalayo yomntu ukubona ukuba umbala uphela ufana kwaye uhambelana, ngakumbi kwiikona ze-concave kunye nemingxuma, akukho mahluko wombala.Kufuneka kungabikho mikrwelo, imikrwelo kunye nezinye iziganeko.Makungabikho mkhondo wamagruzuka.
2. umphezulu wokugquma awuyi kugqabhuka okanye uwe.Ukuba kukho nayiphi na ibala phezu komhlaba, zama ukusula icocekile.Ukuba ibala elingasuliyo, okanye ibala elicacileyo lamanzi, i-watermark, ayinakukhethwa.Enye imeko kukuba ikona yomphetho iya kubonakala kumbala weplating umnyama kwaye uyakhazimla, kukho inkungu engwevu okanye inkungu emhlophe njengamabala, imvakalelo yesandla ayigudi, kwaye ayinakunyulwa.
3. khangela ukuba umphezulu wamanqaku e-electroplating agudileyo kwaye ukuba kukho into ecacileyo ye-convex ye-concave, efana nomphezulu wamaza ongalinganiyo.Uhlolo olukhethekileyo luyafuneka kwiindonga zemveliso ezityebileyo kunye neemilo zomphezulu ezintsonkothileyo.Ukuba isiphumo esipheleleyo silungile, akukho nto icacileyo ye-convex concave, imveliso efanelekileyo.
4. jonga ukuba ukunamathela komphezulu we-electroplated coating kuqinile.Umphezulu wokwambathisa unokuncamathiselwa ngephepha elincamathelayo, kwaye emva koko ukrazulwe kwi-angle ye-45 degree, kwaye akufuneki kubekho i-coating ewayo.
5 Khangela umphezulu womgangatho ongaphakathi, kwaye akuyi kubakho zimpawu zokuhlwa.I-Burr ayifumaneki, i-burr kulula ukuvela kwindawo ene-angle ebukhali kunye nomgca wokufa.
6. ukuba i-coating ayikwazi ukuphumelela uvavanyo lwe-salt spray yeeyure ezingama-24, ayinakuthengwa.
Ezi ndlela zingentla ngamanqaku aphambili okuhlolwa kweengcali ezihambelanayo.
