Tuag casting yog ib qho kev paub technology thiab kev lag luam nrov. Nov yog qee qhov kev ceev faj rau ua ntej-plating kev kho mob ntawm zinc alloy tuag castings:
1. Nkag siab txog cov yam ntxwv ntawm zinc alloy tuag castings:
Qhov saum npoo ntawm zinc alloy tuag castings feem ntau zoo li lub npoo ntawm steamed buns, nrog ib tug du thiab ntom hlau txheej 0.02-0.10 hli tuab. Hauv qab no txheej yog ib tug kuj xoob thiab ntxeem tau qauv. Yog li ntawd, thaum lub sij hawm kho tshuab polishing, nws yog ib qho tseem ceeb kom tsis txhob polishing los ntawm cov txheej du thiab ntom. Qhov no tiv thaiv qhov raug ntawm cov khoom ntxeem tau, uas tuaj yeem ua rau blistering, tev, thiab lwm yam tsis xws luag hauv plating.
2. Nkag siab txog cov khoom siv ntawm zinc alloy tuag castings: Thaum lub sij hawm tuag casting txheej txheem, ntau yam txheej txheem tuaj yeem ua rau zinc- nplua nuj thiab txhuas- nplua nuj nyob hauv tib lub zinc alloy tuag casting qhov chaw. Txawm li cas los xij, muaj zog alkalis nyiam yaj nyob rau hauv cov txhuas- nplua nuj theem, thiab cov acids muaj zog nyiam yaj hauv zinc- theem nplua nuj. Yog hais tias muaj zog alkalis los yog acids yog siv nyob rau hauv degreasing los yog etching txheej txheem, nws feem ntau ua rau blistering thiab tev ntawm lub plating thaum lub sij hawm electroplating, heev cuam tshuam cov yield. Yog li ntawd, zinc alloy tuag castings yuav tsum tsis txhob degreased los yog etched nyob rau hauv muaj zog acids los yog alkalis.
