Slip casting yog cov txheej txheem nrov thiab ntau yam hauv kev ua haujlwm ntawm ceramics, tso cai rau kev tsim cov khoom zoo nkauj thiab cov ncauj lus kom ntxaws. Cov txheej txheem no suav nrog kev tsim cov kua av nplaum sib xyaw, hu ua slurry, uas yog nchuav rau hauv plaster pwm. Raws li cov slurry solidifies, nws tsim cov duab uas xav tau ntawm cov khoom. Cov txheej txheem plam casting yog siv dav hauv kev tsim khoom ntawm ob qho tib si kos duab thiab ua haujlwm ceramic.
Kev npaj ntawm Slurry
Thawj kauj ruam hauv plam casting yog kev tsim cov slurry nws tus kheej. Kev ua slurry suav nrog kev sib xyaw dej nrog cov av nplaum zoo los tsim cov kua dej sib xyaw nrog cov nplaum zoo li sib xws. Qhov zoo ntawm cov slurry yog qhov tseem ceeb, vim nws ncaj qha cuam tshuam rau cov khoom kawg qhov kev ntxhib los mos, xim, thiab durability. Ntau yam additives, xws li deflocculants, feem ntau yog qhia rau cov slurry los txhim kho fluidity thiab txo qhov kev pheej hmoo ntawm tawg thaum ziab.
Tsim ntawm Plaster Pwm
Thaum cov slurry tau npaj, cov kauj ruam tom ntej yog tsim cov pwm plaster. Plaster pwm yog ntxeem tau thiab nqus dej, tso cai rau cov dej tawm ntawm cov slurry raws li nws teeb tsa, yooj yim tsim cov khoom siv ceramic. Cov pwm yog ua tib zoo crafted kom muaj kev cuam tshuam lub hom phiaj ntawm cov khoom kawg, thiab nws yog feem ntau tsim los ntawm ntau daim uas tuaj yeem sib sau ua ke thiab disassembled kom yooj yim siv.
Pouring Slurry rau hauv Mould
Cov txheej txheem casting pib nrog lub ncuav ntawm slurry rau hauv pwm. Cov pwm yog tig los yog swirled los xyuas kom meej ib qho txawm txheej ntawm nws sab hauv, tsim ib txheej ntawm solidified av nplaum hu ua cam khwb cia. Qhov ntev ntawm cov txheej txheem pouring tuaj yeem tswj lub thickness ntawm cov cam khwb cia no. Tom qab ib lub sijhawm tshwj xeeb, cov slurry ntau dhau yog nchuav tawm, tawm hauv qab ib daim ntawv hollow ntawm cov duab uas xav tau hauv pwm.
Txheej txheem txheej txheem
Raws li cov slurry txuas ntxiv mus, lub plaster pwm absorbs dej los ntawm cov av nplaum, ua rau nws solidify ntxiv. Cov slurry seem ntawm cov pwm sab hauv tuaj yeem rov qab siv tau rau cov casts tom ntej, txhawb kev ruaj ntseg hauv cov txheej txheem ntau lawm. Thaum cov cam khwb cia tau mus txog qhov xav tau tuab thiab sib xws, pwm qhib, thiab cov khoom siv ceramic tshiab tau ua tib zoo tshem tawm.
Demolding thiab ziab
Tom qab demolding, cov khoom ceramic tau dhau los ua cov txheej txheem ziab kom tshem tawm cov dej noo seem. Qhov no yog ib kauj ruam tseem ceeb, vim tias kev ziab tsis zoo tuaj yeem ua rau deformities lossis tawg. Thaum cov khoom qhuav tag, nws raug rho tawm haujlwm hauv qhov cub kom ua tiav nws qhov kawg hardness thiab durability. Cov txheej txheem tua hluav taws no tseem muab cov xim xav tau rau cov ceramic los ntawm kev sib cuam tshuam ntawm glazes thiab oxides.
Tag nrho cov nyob rau hauv tag nrho cov, plam casting tso cai rau lub efficiency ntawm cov ncauj lus kom ntxaws thiab complex ceramic daim ntawv uas tej zaum yuav nyuaj los yog tsis yooj yim sua los tsim los ntawm lwm txoj kev. Lub versatility thiab rov ua dua ntawm cov txheej txheem no ua rau nws yog lub hauv paus ntawm kev tsim cov khoom siv niaj hnub no, ua rau cov kws ua yeeb yam thiab cov tuam txhab tsim khoom coj lawv lub zeem muag mus rau lub neej hauv ntau yam kev siv.
