Kev tsim khoom txheej txheem ntawm chrome raj

1. Kev npaj saum npoo

Thawj kauj ruam yog tu cov yeeb nkab hlau kom tshem tawm cov av, roj, thiab xeb. Qhov no yog ua tiavncab(siv cov kev daws teeb meem alkaline) thiabpickling(immersing hauv acid kom tshem tawm oxides). Ib qho kom huv paug yaug nrog dej ua raws li nruab nrab cov tshuaj uas tseem tshuav.

2. Electro-plating teeb

Cov yeeb nkab ntxuav yog raus rau hauv cov tshuaj electrolyte muaj cov hlau yaj hlau ions (feem ntau zinc lossis npib tsib). Nws ua raws li tustus kws uanhahode, thaum lub plating hlau ua haujlwm raws li tusnaj hoomCov. Kev ncaj qha tam sim no (DC) tau thov, pib cov tshuaj tiv thaiv hluav taws xob.

3. Electro-plating txheej txheem

Nyob rau hauv hluav taws xob tam sim no, hlau ions los ntawm kev daws teeb meem tso nyiaj rau cov yeeb nkab hlau, sib sau ua ke sib txawv ntawm cov txheej txheem hlau me me. Lub thickness ntawm plating yog nyob ntawm yam zoo liNtev tam sim no ceev, plating lub sijhawm, thiab daws cov pes tsawg leeg.

4. Tom qab kev kho mob

Tom qab plating, cov yeeb nkab undergoestso yaugkom tshem tawm cov tshuaj ntau dhau. Nws yuav yogpassivated(kho nrog cov kua roj chomate) kom txhim kho corrosion tsis kam. Thaum kawg, cov yeeb nkab yogziabTxhawm rau tiv thaiv cov dej me ntsis.

5. Kev Soj Ntsuam Zoo

Cov khoom tiav tau tshawb xyuas rau txheej txheej tuab, nplaum, thiab tsis xws luag uas siv cov qauv zoo liKev Tshuaj Ntsev NtsevlossisKev Saib Xyuas Kev Pom.

Tus txheej txheem no ua kom ntseeg tau tias cov kav dej hlau hluav taws xob electroplated sib ntsib kev lag luam cov qauv rau kev ua haujlwm ntev thiab ua tau zoo.
