Peev castings yog tsim nrog ib tug ze-net zoo, tab sis lawv yuav muaj ib tug me ntsis ntxhib nto tom qab dewaxing theem. Qhov roughness no yog tshwm sim los ntawm cov qauv uas tshuav los ntawm lub hauv paus tseem ceeb ntawm cov pwm ceramic. Feem ntau, qhov chaw tiav yog nyob ib ncig ntawm 125 Ra, uas yuav txawv me ntsis raws li cov khoom siv thiab pwm zoo.
Yuav kom ua tiav qhov chaw du, muaj ntau yam kev kho deg tiav, txhua lub hom phiaj kom ua tiav qhov zoo ntawm qhov chaw. Cov kev kho mob no tuaj yeem cuam tshuam cov khoom tshem tawm lossis siv cov txheej txheem kom zais thiab ua kom lub ntsej muag ntxhib.
Qhov kev xaiv ntawm cov txheej txheem nto tiav yog nyob ntawm cov yam ntxwv xws li qhov ntev ntev, qhov xav tau, thiab cov khoom siv kho tshuab. Cov hauv qab no yog qee qhov kev ua haujlwm saum npoo av uas tuaj yeem xaiv:
Anodizing: Anodizing yog txoj kev kho saum npoo feem ntau siv rau kev nqis peev castings ua los ntawm txhuas. Nws tsim cov txheej txheem oxide tiv thaiv ntawm qhov chaw, txhim kho corrosion kuj thiab muab ntau yam xim xaiv.
Polishing: Polishing yog ib txoj kev uas yuav tshem tawm imperfections thiab ua tiav ib tug du, reflective nto ntawm peev castings. Nws txhim kho cov tsos thiab kev zoo nkauj ntawm qhov chaw.
Kev pleev xim: Painting yog txheej txheej txheej txheej txheej txheej txheej txheej xim los yog txheej txheej yog siv rau kev nqis peev castings. Nws tso cai rau kev hloov kho ntawm cov xim, kev ntxhib los mos, thiab kev tiv thaiv ib puag ncig.
Hmoov Txheej: Hmoov txheej muab qhov ruaj khov thiab pom kev ua tiav. Nws suav nrog kev siv cov hmoov qhuav rau saum npoo ntawm cov castings, ua raws li kev kho hauv qab cua sov. Hmoov txheej muaj ntau yam xim, textures, thiab tiav.
Passivation: Passivation yog cov txheej txheem tshuaj uas pab tshem tawm cov kab mob ntawm qhov chaw thiab txhim kho corrosion kuj ntawm peev castings, tshwj xeeb tshaj yog rau cov hlau tsis muaj steel thiab lwm yam khoom siv corrosion.
Cov kev xaiv saum npoo tiav no tso cai rau kev ua tiav cov yam xav tau thiab kev ua haujlwm ntawm peev castings. Cov txheej txheem tsim nyog tuaj yeem xaiv raws li cov kev xav tau tshwj xeeb thiab kev txiav txim siab xws li qhov loj me, qhov xav tau zoo nkauj, thiab cov khoom siv ua haujlwm.
