Nickel plating, Galvanizing plating, thiab chromium plating muaj qhov sib txawv tseem ceeb hauv cov haujlwm tseem ceeb, tsos pom zoo, thiab muaj cov xwm txheej muaj feem xyuam. Cov kev sib txawv tshwj xeeb yog raws li hauv qab no:
1. Zinc Plating
• Cov kev ua haujlwm tseem ceeb: ua tiav Cathodic kev tiv thaiv los ntawm kev txi lub anode, nrog muaj zog corrosion tsis kam. Nws yog kev lag luam anti tshaj plaws - xeb txheej.
• Tsos thiab Kev Ua Tau Zoo: Cov nplaim tshwm sim nyiaj {{mo} grey lossis bluish {}} mov dawb, nrog cov npub me me. Lub hardness yog tsawg (hais txog HV 70-110), thiab nws yog ib txwm khawb; Nws tuaj yeem txhim kho ntxiv hauv corrosion tsis kam los ntawm passivation (xws li xim zinc, dawb txaus.
• Muaj cov xwm txheej cuam tshuam: tsawg {{{{{0} Tus nqi, siab} Kev ua lag luam cheem taus, thiab kho kho kho kho kho kom zoo nkauj txhua hnub.
2. Npib Plating
• Cov kev ua haujlwm tseem ceeb: Muab ob qho tib si corrosion tsis kam thiab kho kom zoo nkauj. Cov txheej txheej ntov thiab tuaj yeem tiv thaiv kev sib cuag nrog huab cua thiab ya raws.
• Tsos thiab Kev Ua Tau Zoo: Cov nplaim tshwm sim nyiaj - dawb nrog lub ntsej muag ci (tuaj yeem ua rau hauv daim iav tiav); Lub hardness yog qhov nruab nrab (kwv yees HV 150-300), thiab nws cov coj coj tsis zoo yog qhov zoo dua li ntawm galvanizing; Feem ntau, tooj plating yog thov ua ib txheej puag ua ntej los txhim kho adhesion thiab corrosion tsis kam.
• Cov xwm txheej tso cai: haum rau cov khoom siv uas yuav tsum tau muaj ob qho tsos xeb, xws li cov khoom siv hauv tsev thiab cov khoom siv hluav taws xob.
3. Chrome plating
• Cov kev ua haujlwm tseem ceeb, kev tshwj xeeb hnav tsis kam, corrosion tsis kam thiab cov khoom zoo nkauj, nrog cov tawv tawv.
• Tsos thiab Kev Ua Tau Zoo: Lub saum npoo yog ci nyiaj - dawb, nrog kev ua kom muaj zog thiab kev siv zog; Tsis tshua muaj neeg tawv tawv (kwv yees HV 800 - 1200), tiv taus kev hnav, kub thiab oxidation; Cov txheej txheem yog cov nyom (feem ntau yog "tooj liab {}}}}} chrome" ntau txheej txheej), nrog tus nqi siab tshaj plaws), nrog tus nqi siab tshaj.
• Cov xwm txheej thov: Cheebtsam tseem ceeb nrog kev hnav siab loj, muaj kev ua kom zoo nkauj, xws li lub log tsheb, cov cuab yeej siv hluav taws xob hydraulic, thiab cov khoom siv hauv chav dej.
