Electroplated Galvanized Chromium Zaj duab xis ntawm Hluav Taws Xob Hluav Taws Xob: Ib Lub Tshuab Kho Nto Tshiab los hloov Electroplating

Electroplated Galvanized Chromium Zaj duab xis ntawm Hluav Taws Xob Hluav Taws Xob: Ib Lub Tshuab Kho Nto Tshiab los hloov Electroplating

Electroplating yog hais txog nyob rau hauv cov ntsev tov uas muaj cov hlau yuav plated. Ib txoj kev ua txheej txheem saum npoo uas siv cov hlau substrate tau plated ua cov anode thiab tso cov cations ntawm cov hlau xav tau hauv cov txheej txheem plating rau ntawm qhov chaw ntawm lub substrate los ntawm electrolysis, tsim ib txheej. Ob qhov teeb meem tseem ceeb hauv cov txheej txheem electroplating yog hydrogen embrittlement thiab hnyav ib puag ncig.

Muaj ob txoj kev pom ntawm txoj kev hydrogen invades lub substrate thaum lub sij hawm electroplating txheej txheem. Ib qho kev pom qhia tias oxygen feem ntau nkag mus rau hauv lub substrate thaum ntxov ntawm electroplating, thaum lub sij hawm thib ob pom pom tias hydrogen yog thawj zaug muaj nyob rau hauv hydrogen ntxiab ntawm txheej thaum lub sij hawm electrodeposition txheej txheem, thiab ces maj diffuses mus rau hauv lub substrate. Lub xub ntiag ntawm hydrogen nyob rau hauv cov hlau substrates tuaj yeem ua rau muaj kev ntxhov siab, thiab kev ntxhov siab corrosion feem ntau ua rau muaj kev puas tsuaj loj, ua rau muaj kev phom sij rau tus kheej thiab kev nyab xeeb.

Thaum lub sij hawm tag nrho cov txheej txheem electroplating, cov pa khib nyiab, dej khib nyiab, thiab slag generated muaj feem cuam tshuam rau ib puag ncig. Nws tau kwv yees tias kwv yees li ntawm 600 lab tons ntawm cov hlau tsis huv hauv dej, 50000 tons ntawm cov khib nyiab pov tseg, thiab 50 lab m3 ntawm cov kua qaub yog tawm ntawm electroplating txhua xyoo. Ntawm lawv, electroplating pov tseg kua thiab dej khib nyiab muaj kev cuam tshuam loj rau ib puag ncig.

Nrog rau kev txhim kho txuas ntxiv ntawm tib neeg kev paub txog ib puag ncig, nws pom tau tias qhov teeb meem ntawm cov pa phem loj hauv cov tsoos electroplating tau nce zuj zus. Cov neeg cia siab tias yuav muaj cov txheej txheem tshiab uas tuaj yeem txuag tau cov peev txheej ntau dua, muaj kev ua haujlwm zoo tshaj plaws los tiv thaiv corrosion piv rau cov txheej txheem galvanized, thiab tsis ua rau ib puag ncig.

2. Txog Zinc Chromium Zaj duab xis

Zinc chromium zaj duab xis, tseem hu ua Dacromet (Lus Askiv lub npe), yog flake zinc aluminium chromate tiv thaiv txheej, txheej txheem tshiab rau kev tiv thaiv kev xeb hlau, thiab kev siv tshuab siab thiab tshiab rau kev kho saum npoo hauv ntiaj teb niaj hnub no. Vim lub fact tias nws tag nrho cov txheej txheem txais ib tug kaw voj txheej txheej txheem, nws muaj tus yam ntxwv ntawm tag nrho cov tswj cov pa phem generated nyob rau hauv cov txheej txheem ntau lawm. Yog li ntawd, zinc chromium zaj duab xis tau lees paub tias yog ib puag ncig tus phooj ywg thiab cov khoom ntsuab.
