Cov cuab yeej tiv thaiv kab mob dab tsi yog siv rau electroplating chromium ntawm tus pas nrig piston ntawm lub tshuab hluav taws xob cua sov?

Tau ntev, cov txheej txheem kho saum npoo ntawm piston rods hauv Suav teb tau ua raws li cov txheej txheem chromium plating. Chromium plating tsis tuaj yeem kho qhov loj ntawm qhov sib txhuam ntawm qhov piston pas nrig, tab sis kuj tseem txhim kho qhov zoo ntawm qhov chaw, tshwj xeeb tshaj yog qhov hnav tsis kam. Txawm li cas los xij, electroplating chromium ntawm tus pas nrig piston tuaj yeem tsim cov chromic acid, uas yog cov khoom siv corrosive heev uas ua rau khaus thiab corrosive. Kev cuam tshuam rau chromic acid thaum cov neeg ua haujlwm ua pa tuaj yeem ua rau khaus rau lawv cov tawv nqaij, qhov muag, thiab ua pa sab sauv. Yog li kev tiv thaiv yuav tsum tau ua rau chrome plating.

Dab tsi yog cov cuab yeej tiv thaiv ua pa siv rau electroplating chromium ntawm tus pas nrig piston? Changzhou chrome plating qhia rau koj:

1. Cov phom sij ntawm cov hlau electroplating feem ntau suav nrog kev ua pa ntawm lub cev thiab kev phom sij ntawm daim tawv nqaij. Vim tias qhov ua tau zoo tam sim no tsis tshua muaj nyob rau hauv cov txheej txheem electroplating, ntau cov pa roj thiab cov pa khib nyiab yuav raug tsim tawm. Yog tias tsis muaj kev tswj xyuas thiab kev tswj xyuas kom zoo, cov pa roj yuav nqa cov chromium acid tee thiab tawg mus rau hauv qhov chaw ua haujlwm, ua rau muaj kev phom sij rau kev ua pa; Tsis tas li ntawd, thaum plating qhov chaw nce thiab nqis, lawv tuaj yeem nkag mus rau hauv cov tshuaj chromic acid plating, uas tuaj yeem ua rau muaj kev phom sij ntawm daim tawv nqaij vim yog corrosiveness ntawm chromic acid. Yog li ntawd, yog tias kev siv cov cuab yeej tiv thaiv raug txiav txim siab raws li kev phom sij, cov ntsiab lus tseem ceeb yog cov cuab yeej tiv thaiv ua pa thiab cov hnab looj tes tiv thaiv.

2. Los ntawm qhov kev xav ntawm nws cov khoom, chromic acid muaj lub siab kub kub thiab feem ntau tsis muaj nyob rau hauv daim ntawv gaseous. Txawm li cas los xij, vim tias cov roj tau dhau los ntawm cov tshuaj uas tsim cov huab cua, cov cuab yeej tiv thaiv ua pa yuav tsum tuaj yeem tiv thaiv huab cua ntau dua li cov roj acid. 3M tswv yim: Hauv kaum zaus TLV, plua plav npog tuaj yeem siv los tiv thaiv chromic acid droplets.
