1.Dab tsi yog cov txheej txheem tiv thaiv corrosion ntawm galvanized coils thiab palladium-plated coils feem?
Zinc-plated coils: Sacrificial anode tiv thaiv: Zinc yog ntau reactive dua hlau, tiv thaiv steel substrate los ntawm nws tus kheej corrosion.
Palladium-plated coils: Inert lub cev barrier: Palladium nws tus kheej yog qhov ruaj khov heev, tsim cov txheej tiv thaiv ntom ntom uas cais cov substrate los ntawm corrosive media.
2.Dab tsi yog qhov sib txawv tseem ceeb ntawm kev xeb ntawm galvanized coils thiab palladium-plated coils?
Galvanized coils: Electrochemical corrosion, dawb xeb (basic zinc carbonate), liab xeb (corrosion ntawm lub hauv paus hlau).
Palladium-plated coils: Inert lub cev barrier: Palladium nws tus kheej yog qhov ruaj khov heev, tsim cov txheej tiv thaiv ntom ntom uas cais cov substrate los ntawm corrosive media.
3.Dab tsi yog qhov txawv ntawm corrosion kuj?
Atmospheric Ib puag ncig: Galvanized coils tuaj yeem muab kev tiv thaiv rau xyoo lossis ntau xyoo hauv qhov chaw sab nraum zoov. Palladium-plated coils, txawm li cas los xij, suav tias yog kev xeb mus tas li- tiv taus nyob rau hauv ib puag ncig zoo li no.
Ntsev Tsuag Ib puag ncig: Qhov no yog ib qho kev siv ceev nrawm rau kev ntsuas kev tiv thaiv corrosion.
Galvanized Coil: Ib qho yooj yim galvanized coils tuaj yeem tsim xeb dawb tom qab kaum teev thiab xeb liab ntawm lub substrate tom qab ntau pua teev.
Palladium-plated Chev: Yooj yim dhau 1000- teev nruab nrab ntsev tshuaj tsuag yam tsis muaj corrosion, ib qho yuav tsum tau ua rau high-end electronic connectors.
Chemical Ib puag ncig:
Galvanized Coil: Ua rau ob qho tib si acids thiab alkalis. Nws corrodes sai heev nyob rau hauv acid los nag thiab yaj nyob rau hauv muaj zog alkaline ib puag ncig.
Palladium{0}}plated Chev: Muaj cov kua qaub thiab alkali zoo heev; nws tsuas yog corrodes nyob rau hauv muaj zog oxidizing acids (xws li aqua regia) los yog nyob rau hauv tej yam kev mob.
4.Dab tsi ua rau palladium xeb tsim?
Ua rau: Palladium muaj peev xwm nqus tau hydrogen. Hauv hydrogen- muaj ib puag ncig (xws li thaum lub sij hawm electroplating los yog kev sib cuag nrog cov organic teeb meem decomposition thaum siv), hydrogen atoms tuaj yeem nkag mus rau hauv palladium lattice, ua rau palladium txheej ua nkig, tsim microcracks, thiab thaum mob hnyav, txawm tias pulverize.
Kev cuam tshuam: Qhov no ua rau qhov tsis ua haujlwm ntawm plating lub tshuab tiv thaiv thiab kev sib cuag hluav taws xob.
Kev daws: Feem ntau, txheej nyias nyias ntawm cov kub kub yog plated rau saum txheej palladium raws li txheej tiv thaiv, tiv thaiv "palladium lom" thiab muab kev tiv thaiv zoo dua thiab hnav tsis kam. Qhov no yog cov txheej txheem "palladium-nickel plating + flash kub plating".
5.Peb yuav tsum xaiv li cas raws li qhov sib txawv ntawm daim ntawv thov scenarios?
Rau kev tsim tsev, tsim lub tsheb lub cev, thiab ua cov khoom vaj tsev: galvanized coils yog qhov kev xaiv zoo tshaj plaws thiab kev lag luam.
Rau kev tsim khoom siab -kev ntseeg siab ntawm cov khoom siv hluav taws xob sib txuas, cov cuab yeej ntsuas kev sib cuag, thiab cov khoom siv dav hlau: palladium- plated coils yog qhov kev xaiv tseem ceeb. Txawm hais tias kim heev, lawv qhov kev ruaj ntseg tsis sib xws, kev tiv thaiv corrosion, thiab cov khoom hluav taws xob yog qhov tseem ceeb los ua kom lub sijhawm ntev - txhim khu kev qha ntawm cov khoom siv.
