Kev kho ua ntej ntawm electroplated hlau nto rau hluav taws xob cua sov raj

Kev kho ua ntej ntawm electroplated hlau nto rau hluav taws xob cua sov raj

Hlau nto pre-kev kho mob inevitably undergoes oxidation thaum lub sij hawm ntau yam kev kho cua sov, mechanical processing, tsheb thauj mus los, thiab cia txheej txheem, uas ua rau ib tug uneven txheej ntawm oxide. Nyob rau tib lub sijhawm, nws tseem raug rau ntau yam roj paug thiab adsorption ntawm lwm yam impurities.

Cov roj stains thiab qee cov adsorbents, nrog rau cov txheej txheem oxide nyias, tuaj yeem ntxuav nrog cov kuab tshuaj, tshuaj kho, kho kho tshuab, lossis kho ncaj qha nrog tshuaj. Rau cov hlau oxidized hnyav heev nrog cov txheej oxide tuab, cov kuab tshuaj ntxuav thiab tshuaj tsis tuaj yeem siv ncaj qha, thiab nws yog qhov zoo tshaj rau kev kho tshuab ua ntej.

Feem ntau, cov khoom siv hlau kho tau muaj kev ua haujlwm siab thiab ua rau muaj kev cuam tshuam ntau dua los ntawm cov plua plav, noo noo, thiab lwm yam. Vim li no, cov hlau kho tau zoo yuav tsum tau sib txuas kom sai li sai tau.

Lub sij hawm cia ntawm hlau tom qab kev kho mob sib txawv yog raws li nram no:

Aluminium alloy kho nrog ntub sandblasting rau 72 teev;

Aluminium alloy kho nrog chromic acid sulfuric acid rau 6 teev;

Anodized aluminium alloy, 30 hnub;

Stainless hlau kho nrog sulfuric acid, 20 hnub;

Steel sandblasted rau 4 teev;

Brass kho nrog ntub sandblasting rau 8 teev.

GREENTECH molecular conversion technology yog ib puag ncig tus phooj ywg. Tom qab kev kho mob, cov khoom muaj qhov zoo xws li hnav tsis kam, kub tsis kam, corrosion kuj, tsis tev ntawm vuam nto, thiab txhim kho conductivity. Qhov kev ua tau zoo ua rau kev ua lag luam muaj peev xwm ntau dua li cov electroplating zoo tib yam lossis tshuaj electroplating. Cov cuab yeej siv tau rau txhua yam hlau thiab tau dhau SGS daim ntawv tshaj tawm.

Yuav kom txuag tau lub zog thiab cov peev txheej, cam khwb cia hlau cov khoom siv hauv tsheb kuj tseem niaj hnub ua nyias thiab sib dua. Raws li qhov txhais tau tias, ntau thiab ntau lub tuam txhab tau txais kev siv zog ntau dua cov hlau nplaum (cov hlau nplaum) los hloov cov qub qub cam khwb cia hlau (vermicular graphite hlau). Txawm li cas los xij, qhov nyuaj ntawm cov hlau cam khwb cia hlau yog qhov siab, thiab thaum siv cov khoom siv hlau cam khwb cia, suav nrog vermicular graphite cam khwb cia hlau, cov tuam txhab xav tau los txhim kho lawv txoj kev nrawm thiab kev ua haujlwm, txhawm rau txo lub sijhawm xa khoom thiab txo kev ua haujlwm. tus nqi. Yog li ntawd, rau cov cuab yeej txiav, nws tseem tsim nyog los tsim cov khoom lag luam uas tuaj yeem ua tiav lub neej ua haujlwm ntev thiab ua haujlwm ruaj khov.

AC410K tau tsim los ua kom tau raws li qhov xav tau saum toj no. CVD (tshuaj vapor deposition) txheej yog siv los txhim kho hnav tsis kam thiab tev tawm los ntawm txheej txheej zoo thiab du titanium carbide (TiCN) thiab txhuas oxide (Al2O3) films. Lub thickness ntawm Al2O3 zaj duab xis yog ob npaug ntawm cov khoom qub. Los ntawm optimizing cov zaj duab xis-forming tej yam kev mob, lub thickness tau nce thaum tuav lub tib particle loj thiab ceev. Nyob rau hauv txoj kev no, kev ua haujlwm siab thiab ua haujlwm tau zoo tuaj yeem ua tiav ntau dua 1.5 npaug ntawm cov khoom qub.

Tsis tas li ntawd, los ntawm kev ua kom lub ntsej muag ntawm cov txheej txheem thiab cov kev sib tshuam ntawm cov txheej txheem uas ua rau cov txheej txheem du, lub zog adhesion thiab melting tsis kam ntawm cov txheej yog txhim kho. Nrog rau qhov kev ua haujlwm no, cov teeb meem hauv kev ua tiav tuaj yeem raug tshem tawm - zaj duab xis rupture thaum lub sij hawm cov tawv nqaij dub (oxide zaj duab xis ntawm cov hlau nto) kev ua thiab kev ua haujlwm tsis zoo ntawm cov cuab yeej, ua tiav kev ua haujlwm ruaj khov.
