Qhov yooj yim tshaj plaws rau cov khoom siv hluav taws xob sib txuas yog hauv kab hluav taws xob. Cov khoom sib txuas tau muaj txiaj ntsig zoo rau pawg thawj coj-rau-board txuas ntawm cov laug cam. Cov khoom sib txuas muaj txiaj ntsig zoo rau xaim-rau-xaim lossis xaim-rau-board txuas ntawm txoj hlua hluav taws xob ntawm txhua lub tsheb. Nws kuj tseem siv nyob rau lwm qhov chaw, xws li cov cuab yeej tsim khoom, tsheb, cov dav hlau thiab lwm qhov chaw uas xav tau kev sib txuas.
Qhov tseem ceeb tshaj plaws ntawm qhov txuas hluav taws xob yog qhov kawg ntawm lub dav hlau thaiv ntawm qhov sib cuag. Lub davhlau ya nyob twg thaiv yog sib npaug rau qhov txuas me me thiab nruab nrab. Nws txuas qee cov khoom siv nrog cov yam ntxwv zoo ib yam lossis sib txawv los xyuas kom meej tias qee cov khoom tuaj yeem txuas tau yooj yim. Khiav lossis ua kom ntseeg tau tias qhov tam sim no tuaj yeem ntws tau zoo, yog li txhua lub cuab yeej tuaj yeem ua haujlwm. Feem ntau ntawm cov ntaub ntawv raw ntawm hom dav hlau no tsis zoo ib yam. Vim tias qhov chaw siv feem ntau muaj kev ua haujlwm sib txawv thiab cuam tshuam ib puag ncig, cov khoom siv yuav txawv. Qee qhov yuav tsum yog cov khoom siv hlau, qee qhov yuav tsum yog yas, thiab qee qhov yuav tsum tau ua kua, thiab qee qhov yuav tsum tau khov. Hauv ntej, xaiv cov ntaub ntawv nyob ntawm cov ntsiab lus.
Cov txheej txheem txheej txheej txuas yog tus yuam sij kom ntseeg tau tias siv tau cov khoom siv txuas hluav taws xob
Thaum xaiv txheej txheej rau lub tshuab hluav taws xob txuas hluav taws xob, qhov kev txiav txim siab tseem ceeb yog ib puag ncig ib puag ncig ntawm daim ntawv thov. Cov khoom sib txuas tau muab faib ua peb yam: rau kev siv dav, electroplating tin yog qhov feem ntau, vim tias tin yog tus nqi ntau dua, tab sis cov khoom ntawm tin yog qhov muag muag, txhawm rau kom ntseeg tau zoo rau kev sib cuag, muaj zog tiv tauj siab ( tsawg kawg 100g) xav tau. Qhov zaus ntawm kev tso thiab tshem tawm feem ntau yog qis. Nws tsuas muaj qhov yooj yim tiv thaiv kev txhim kho corrosion. Kev ua haujlwm kub yog qhov tsawg. Kev ua haujlwm kub ntawm tooj dag lossis tooj liab electroplating tuaj yeem ncav cuag 110 ° C. Tin plating tuaj yeem ncav cuag 190 ° C. Rau kev tso ntau zaus, kub plating feem ntau xav tau. Rau kev ua haujlwm siab dua, yuav tsum muaj lwm txheej txheej, xws li tooj liab electroplating npib tsib xee mus txog 340 ° C, tooj liab lossis tooj dag tooj liab electroplating nickel txog 250 ° C.
Rau kev siv cov ntaub ntawv me me teeb tsa nrog kev ntseeg siab ntawm cov dav sib txuas thiab siv kev sib tiv tauj me me, kub plating feem ntau siv, thiab kev tiv thaiv xeb ntawm kub kuj tseem ceeb heev. Nickel feem ntau yog siv ua txheej txheej hauv qab ntawm cov xim kub, thiab feem ntau ntawm cov hlau tiv tauj yog npib tsib xee plated (tooj liab yuav tsum tau plated ua ntej). Kev ua haujlwm ntawm palladium tsis zoo dua li cov kub, thiab nws tau siv ntau zaus los hloov cov xim kub hauv qee qhov txwv. Tam sim no, tus nqi kub tseem nce ntxiv, thiab ntau thiab ntau cov khoom lag luam tau plated nrog palladium nickel-based alloys. Cov ntsiab lus tiv tauj nyiaj muaj cov coj ua tau zoo, tab sis nyiaj yog yooj yim heev rau oxidize hauv huab cua, yog li nws tsuas tuaj yeem siv hauv qhov xwm txheej tshwj xeeb.
