Hluav taws xob cua sov raj 6. Vim li cas cov khoom plated yuav tsum tau muab ntxuav nrog dej huv los ntawm cov roj chemical tshem tawm kom tsis muaj zog acid corrosion?

Hluav taws xob cua sov raj 6. Vim li cas cov khoom plated yuav tsum tau muab ntxuav nrog dej huv los ntawm cov roj chemical tshem tawm kom tsis muaj zog acid corrosion?

Teb: Vim hais tias cov tshuaj degreasing ib txwm yog alkaline, yog tias cov tshuaj degreasing ncaj qha coj mus rau hauv cov kua qaub corrosion, nws yuav pib cov tshuaj tiv thaiv nruab nrab ntawm cov kua qaub thiab alkali, txo cov concentration thiab cov nyhuv ntawm cov kua qaub. Cov khoom ntawm neutralization cov tshuaj tiv thaiv adheres rau lub workpiece, uas yuav cuam tshuam rau qhov zoo ntawm txheej. Yog li ntawd, tom qab tshuaj degreasing, lub workpiece yuav tsum tau ntxuav nrog dej huv ua ntej nkag mus rau cov kua qaub corrosive.

7. Dab tsi yog qhov ua rau burrs thiab coarse hais nyob rau hauv txheej electroplating? Peb yuav daws tau lawv li cas?

Teb: Burrs thiab coarse hais tshwm rau ntawm txheej, feem ntau tshwm sim los ntawm kev sib kis ntawm tshem tawm impurities hauv cov tshuaj plating. Nws qhov chaw yog: hmoov av hauv huab cua, sludge los ntawm anode, thiab hydrolysis khoom ntawm hlau impurities. Tsis tas li ntawd, kuj tseem muaj qhov txawv txav ntawm cov tshuaj plating thiab kev ua haujlwm tsis zoo. Qhov kev daws teeb meem yog los kho qhov muaj pes tsawg leeg ntawm cov tshuaj plating thiab kev ua haujlwm. Yog tias nws tshwm sim los ntawm kev tshem tawm impurities, cov tshuaj plating yuav tsum tau lim.

8. Dab tsi yog cov txheej txheem yooj yim rau kev npaj cov tshuaj electroplating

Teb: Cov txheej txheem yooj yim rau kev npaj cov tshuaj electroplating yog raws li hauv qab no:

(1) Muab cov tshuaj electroplating uas yuav tsum tau ua nrog cov kua txiv hmab txiv ntoo zoo rau hauv qhov qhib (groove me) ua ntej, thiab tom qab ntawd ntxiv cov dej uas tsim nyog rau yaj. Ceev faj tsis txhob muab cov tshuaj ncaj qha mus rau hauv lub plating zawj.

(2) Cov impurities uas muaj nyob rau hauv cov tshuaj yuav raug tshem tawm los ntawm ntau yam tshuaj thiab kho nrog activated carbon.

(3) Cov tshuaj uas tau kho thiab sab laug yog lim mus rau hauv lub plating huv da dej, thiab dej ntxiv rau tus qauv.

(4) Kho cov txheej txheem plating specifications (pH nqi, kub, additives, thiab lwm yam).

(5) Thaum kawg, siv qhov ceev tam sim no rau electrolytic deposition kom tshem tawm lwm yam hlau ion impurities kom txog rau thaum cov tshuaj tsim nyog rau kev ua haujlwm.
