Tooj liab muab faib ua: tooj dag, tooj liab, liab tooj liab, dawb tooj liab. Vim muaj kev cuam tshuam ntawm ib puag ncig, tooj liab saum npoo yuav raug oxidized rau qhov sib txawv, yog li nws kuj xav tau kev tiv thaiv saum npoo kom nws ci zoo li tshiab thiab corrosion kuj thiab oxidation tsis kam rau lub sij hawm ntev. Qhov ntawd yuav tsum tau ua ntau yam txheej txheem ntawm tooj liab nto.
Cov txheej txheem kev kho tooj liab feem ntau suav nrog cov hauv qab no:
1. Kev tu zoo ntawm tooj liab: nws yog tsuas yog los kho cov xim ci ntawm tooj liab nws tus kheej tom qab ntxuav cov stains, impurities, me ntsis, roj stains thiab lwm yam av ntawm tooj liab. Nws kuj yog ib qho tsim nyog txheej txheem ua ntej tooj liab passivation.
2. tooj liab passivation: raws li peb txhua tus paub, lub luag haujlwm tseem ceeb ntawm passivation yog tiv thaiv oxidation thiab corrosion. Raws li tooj liab yog cov hlau nquag, nws yog qhov tshwj xeeb tshaj yog yooj yim rau oxidize thiab loj hlob me ntsis nyob rau hauv cov av ntub los yog tshwj xeeb ib puag ncig, thiab txawm pom verdigris. Yog li ntawd, tooj liab passivation yog ib qho ntawm cov txheej txheem tsim nyog tshaj plaws. Nws tuaj yeem tiv thaiv qhov chaw ntawm tooj liab zoo.
3. Anodic oxidation: siv tooj liab ua anode thiab tsim oxide zaj duab xis ntawm nws qhov chaw los ntawm electrolysis. Oxide films hloov lub xeev ntawm lub xeev thiab cov khoom, xws li nto xim, txhim kho corrosion kuj, txhim kho hnav tsis kam thiab hardness, tiv thaiv nto ntawm tooj liab qhov chaw, thiab lwm yam.
4. Electroplating: lub hom phiaj ntawm electroplating yog los coated tooj liab substrate nrog hlau txheej thiab hloov cov khoom nto los yog qhov ntev ntawm cov tooj liab substrate. Electroplating tuaj yeem txhim kho corrosion kuj ntawm tooj liab, nce hardness, tiv thaiv kev puas tsuaj, txhim kho conductivity, smoothness, kub tsis kam thiab nto zoo nkauj.
5. Copper tshuaj polishing: raus cov tooj liab ncaj qha rau hauv cov tshuaj tooj liab tshuaj polishing kua, kom lawv tuaj yeem ncav cuag cov xim zoo nkauj li ci li tshiab, thiab tshem tawm cov oxide nto sai sai. Qhov loj me ntawm qhov chaw yuav hloov raws li, tab sis nws tuaj yeem tswj tau manually. Cov tooj liab qhov chaw tom qab tshuaj polishing yuav tsum tau passivated sai li sai tau los tiv thaiv lawv los ntawm oxidized thiab discolored dua.
