6 Yam Koj Yuav Tsum Paub Txog Platinized Titanium Anodes (5)
(Txuas ntxiv)
Kev tsim cov platinized titanium anodes tau hloov zuj zus thiab txhim kho nyob rau hauv ob lub xyoo dhau los. Txawm hais tias cov txheej txheem electrodeposition rau txheej platinum tseem nrov, qhov nyuaj ntawm kev ua tiav txheej txheej ntawm titanium tau kov yeej los ntawm pre-roughening titanium nto thiab pre-coating lub etched substrate nrog ib tug nyias nyias zaj duab xis ntawm ib tug conductive primer.
Raws li qee qhov kev tshawb fawb, platinum coat thickness feem ntau txawv ntawm ib mus rau tsib microns, thiab hauv kev siv tshwj xeeb ntawm kev tiv thaiv cathodic, (lub thickness) tuaj yeem mus txog 20 microns. Rau kev tiv thaiv cathodic ntawm onshore choj decks, tooj liab-cored titanium nrog 2.5-micron platinum sheath tau tsim. Cov kev tshawb fawb tau xaus lus ntxiv tias nyob rau hauv ib qho kev daws teeb meem NaCl, platinum noj yuav tsawg dua 0.1 micrograms ib ampere-teev, thaum nyob rau hauv dej hiav txwv ( kaum feem pua saturation) nws tuaj yeem mus txog ib microgram ib ampere-teev.
Rau cov cathodic tiv thaiv systems ntawm lub hwj chim chaw nres tsheb condensers siv ib tug sib tov ntawm dej thiab seawater, lub platinum noj npaum li cas tshwm sim vim lub simultaneous evolution ntawm oxygen nrog rau cov tshuaj chlorine, thiab nrog dej qab ntsev, vim hais tias muaj cov yaj nyob rau hauv cov khoom, kev noj ntawm ib txhij. platinum nce mus rau kaum ntawm micrograms ib ampere-teev.
Nyob rau hauv cov ntaub ntawv ntawm nickel electroplating, lub xub ntiag ntawm brightening agents yuav cuam tshuam rau platinum noj cov nqi, whereas qab zib cov ntsiab lus nyob rau hauv lub brine feedstock nyob rau hauv steel hlab ntsha accentuated tus nqi ntawm platinum noj.
