Yam dab tsi cuam tshuam rau qhov zoo ntawm electroplating zoo ntawm zinc alloy tuag castings?

Rau zinc alloy tuag castings los ua electroplated nto kho, qhov txuas no tseem ceeb heev. Yog tias qhov electroplating tsis ua tiav zoo, tag nrho cov haujlwm nyob rau theem pib yuav raug pov tseg. Yog li ntawd, peb yuav tsum xyuam xim rau cov txheej txheem electroplating ntawm cov khoom. Tom qab ntawd qhov zoo ntawm electroplating yog cuam tshuam los ntawm cov yam tseem ceeb. Huayin Tuag Casting cov ntsiab lus hauv qab no rau koj:

1. Rau kev xaiv cov khoom siv raw rau zinc alloy tuag-casting qhov chaw, cov khoom siv hauv lub tebchaws yuav tsum raug xaiv rau cov khoom tuag-casting.

 2. Kev tsim cov zinc alloy tuag-casting qhov chaw yuav tsum tsim nyog. Cov duab ntawm qhov tuag-casting yuav tsum xav txog qhov zais qhov muaj peev xwm ntawm electroplating, thiab sim txo qhov tsis yog los ntawm qhov, kom nws tsis yooj yim los nqa cov tshuaj hauv dej ntxuav. Txiav cov kaum ntse ntse thiab lwm qhov chaw kom cov kab hluav taws xob sib npaug sib npaug thaum lub sij hawm electroplating.

  3. Cov txheej txheem tuag-casting thiab tuag-casting pwm tsim yog tsim nyog, yog li ntawd cov tuag-casting qhov chaw yuav tsis raug kev txom nyem los ntawm cov shortcomings ntawm shrinkage, pinhole thiab looseness. Cov kev tsis txaus siab saum toj no yuav cuam tshuam ncaj qha rau adhesion ntawm txheej.

 4. Nyob rau hauv cov txheej txheem ntawm zinc alloy tuag castings, sim txo qhov tshwm sim ntawm segregation. Yog hais tias aluminium segregates nyob rau hauv qee qhov chaw, txhuas yuav ua ntej yaj thaum lub sij hawm degreasing, uas yuav ua rau pores thiab pinholes ntawm qhov tuag-casting thiab tsis tuaj yeem ntxuav, ua rau lub zog tsis zoo, ua rau tev thiab blistering ntawm txheej.

 5. Ua tib zoo saib cov nplai thaum lub sij hawm sib tsoo thiab polishing txheej txheem. Txheej zoo ntawm 0.05~0.1mm tsim thaum lub sij hawm txias txheej txheem ntawm tuag casting yog ib qho tseem ceeb heev rau electroplating. Kev poob ntawm cov txheej zoo yuav tsum raug txo kom ntau li ntau tau thaum lub sij hawm sib tsoo thiab polishing. Yog tias txheej txheej no yog hauv av thiab pov tseg, Dab tsi yuav tshwm sim yog cov qauv ntxeem tau, thiab tsis muaj txheej txheej electroplating zoo yuav tau txais ntawm cov txheej txheem no.

  6. Cov txheej txheej tooj liab-nickel-chromium electroplating txheej txheej muaj ntau hom plating yog txheej txheej tsis zoo plating txheeb ze rau substrate. Ntev npaum li kev kho tshuab zoo, zinc alloy qhov chaw yuav corrode nyob rau hauv cov huab cua ntub, yog li nws yog ib qho tsim nyog los xyuas kom meej tias cov txheej plating yog qhov dawb. Txwv tsis pub, cov khoom siv corrosion ntawm zinc alloy yuav ua rau blistering ntawm txheej. Piv nrog rau cov hlau qhov chaw, cov txheej txheej plating yuav tsum tuab dua kom haum rau zinc alloy tuag castings.

7. Cov seem ntawm qhov tuag-casting thaum lub sij hawm tuag-casting thiab machining yuav tsum tau muab ntxuav kom ntau li ntau tau tom qab ua. Vim tias qhov seem yog cov hlau tiag tiag, nyob rau hauv txhua txoj kev ntawm electroplating, nws yuav hnov ​​​​mob nrog cov tshuaj thiab ua rau cov tshuaj plating puas tsuaj, uas yuav cuam tshuam rau qhov zoo ntawm plating.
