Rau high-end cosmetic zaub, feem ntau lawv muaj hlau hniav nrog PVD nqus txheej. dab tsi yog PVD ??
PVD yog Physical Vapor Deposition .. Nws yog hais txog kev ua yeeb yaj kiab (technology preparation) uas lub cev siv cov khoom ua haujlwm hauv plhaub ua haujlwm hauv plhaub.
lub hauv paus ntsiab lus yog siv cov low-voltage, siab dua tam sim no hauv cov tshuab fais fab, siv roj tawm mus ua kom lub hom phiaj thiab ua rau cov khoom siv tsis ua pa tsis muaj dab tsi tshwm sim, thiab ceev ceev ntawm cov hluav taws xob siv los siv evaporated tshuaj thiab nws cov tshuaj tiv thaiv khoom ntawm lub workpiece.
PVD coating tshuab muaj kev kub nyhiab, kev ua haujlwm hnyav siab (tsis sib haum xeeb coefficient), zoo corrosion kuj thiab chemical stability, thiab lub neej ntawm zaj duab xis txheej. Ntev; nyob rau tib lub sij hawm, zaj duab xis txheej dhau los ua tau zoo heev rau kev pom ntawm lub workpiece.
Thickness of PVD txheej txheej-Lub thickness ntawm PVD txheej txheej yog micron-teev thiab thinner, feem ntau 0.3μm mus rau 5μm. Tus txheej txheem ntawm txheej txheej txheej feem ntau yog 0.3μm ~ 1μm, ces nws yuav muaj cuam tshuam los ntawm yuav luag Lub cev nqaij daim tawv thiab cov khoom siv ntawm qhov chaw ntawm lub workpiece tau zoo tuaj nrog tus thawj qhov ntev ntawm cov khoom ua haujlwm, tsis ua ntxiv yog yuav tsum tau tom qab plating.
Qhov sib thooj thiab sib txawv ntawm PVD txheej txheem thiab cov tshuaj electroless plating (dej plating) - PVD txheej tsis yog tib yam li cov xim electroless plating. Ob leeg yog nyob rau hauv cov uas ntawm kev kho mob deg, uas yuav tsum tau them ib cov khoom nyob rau hauv lwm los ntawm tej txhais tau tias. Qhov saum npoo ntawm cov khoom. Qhov zoo sib xws ntawm ob yog tias cov PVD txheej txheej tsis muaj kev sib zog ua kom muaj zog ntawm cov khoom ua haujlwm, cov hardness ntawm zaj duab xis txheej yog siab dua, kev coj hnyav thiab corrosion kuj zoo dua, thiab qhov ua tau zoo ntawm cov zaj duab xis txheej yog ruaj khov; tsis muaj ib yam tshuaj lom lossis tshuaj muaj kab mob thaum txheej txheem PVD txheej txheem
