Silica sol casting yog txheej txheem casting uas siv silica sol (silica tov) raws li cov ntaub ntawv binder los tsim cov pwm pwm. Cov hlau castings uas ua los ntawm silica sol casting muaj qhov zoo thiab qhov raug siab thiab qhov dav dav dav dav yog qib siab txog CT4 - CT6. Thiab cov txheej txheem no yog lub ntsiab peev txheej txheej txheem ntawm RMC rau stainless hlau castings thiab alloy steel castings. Peb tau tsim cov thev naus laus zis tshiab ntawm cov khoom siv nplaum kom ua tiav ntau dua kev lag luam thiab cov khoom siv nplaum zoo rau kev nqis peev casting kev lag luam.

Nws yog ib qho kev sib tw uas silica sol casting txheej txheem hloov cov txheej txheem dej iav tsis zoo nyob rau hauv tag nrho precision casting kev lag luam, tshwj xeeb tshaj yog rau stainless hlau casting thiab alloy hlau casting. Dhau li ntawm cov khoom siv molding tshiab, silica sol casting txheej txheem kuj tau tsim kho kom ruaj khov thiab tsis tshua muaj cua sov.
Kev nqis peev (poob ciab) casting yog ib txoj hauv kev ntawm precision casting uas ua rau cov ntsiab lus nyob ze-net-puab cov ntaub ntawv siv rov ua cov qauv siv quav ciab.Kev nqis peev castinglos yog poob ciab yog cov txheej txheem hlau uas feem ntau siv cov qauv siv quav ciab ncig los ntawm lub plhaub ceramic los ua cov pwm ceramic. Thaum lub plhaub dries, siv quav ciab yog melted tam sim ntawd, tawm tsuas yog cov pwm. Tom qab ntawd cov khoom siv casting yog tsim los ntawm cov hlau molten rau hauv cov pwm ceramic.
Raws li qhov sib txawv binders rau lub plhaub tsev, lub peev casting yuav muab faib ua silica sol binder peev casting, dej iav binder peev casting thiab peev casting nrog lawv cov khoom sib tov ua cov ntaub ntawv binder. Silica sol yog ib yam dej-raws li khi nrog ib tug silicic acid colloid qauv. Nws yog ib tug polymer colloidal tov nyob rau hauv uas heev dispersed silica hais yog soluble nyob rau hauv dej. Cov colloidal hais yog spherical thiab muaj ib txoj kab uas hla ntawm 6-100nm. Cov txheej txheem ntawm peev casting los ua lub plhaub yog txheej txheem ntawm gelling. Muaj ntau yam cuam tshuam rau gelation, feem ntau yog electrolyte, pH, sol concentration thiab kub. Muaj ntau hom kev lag luam silica sols, thiab feem ntau siv yog alkaline silica sol nrog cov ntsiab lus silica ntawm 30%. Txhawm rau kov yeej qhov tsis txaus ntawm lub plhaub ntev ua lub voj voog ntawm silica sol plhaub, ib qho kev ziab silica sol tau tsim nyob rau xyoo tas los no. Cov txheej txheem ntawm kev ua silica sol plhaub yog qhov yooj yim. Txhua txheej txheem muaj peb txheej txheem: txheej, xuab zeb, thiab ziab. Txhua tus txheej txheem yog rov ua ntau zaus kom tau txais lub plhaub multilayer ntawm qhov yuav tsum tau ua kom tuab.
Hauv silica sol plhaub ua txheej txheem, ziab yog txheej txheem tseem ceeb tshaj plaws. Los ntawm kev ziab, cov dej yog volatilized, silica sol gels, thiab cov khoom refractory yog ruaj khov ua ke, yog li tau txais lub plhaub muaj zog. Qhov no yog ib qho kev npaj zoo rau lub tom ntej casting.
Lub casting tau txais los ntawm silica sol plhaub ua cov txheej txheem muaj qis nto roughness, siab qhov tseeb thiab ntev lub plhaub ua voj voog. Cov txheej txheem no yog siv dav hauv casting high-temperature heat-resistant alloys, heat-resistant steels, stainless steels, carbon steels, low alloys, aluminium alloys and copper alloys.
Lub silica sol precision poob ciab peev casting txheej txheem yog tsim rau repeatable ntau lawm ntawmnet puab casting Cheebtsamlos ntawm ntau yam sib txawv hlau thiab kev ua haujlwm siab alloys. Txawm hais tias feem ntau yog siv rau cov me me castings, cov txheej txheem no tau siv los ua tiav qhov rooj dav hlau qhov rooj, nrog cov hlau castings txog li 500 kgs thiab aluminium castings txog li 50 kgs. Piv rau lwm cov txheej txheem casting xws li tuag casting lossisxuab zeb casting, nws tuaj yeem yog tus txheej txheem kim. Txawm li cas los xij, cov khoom uas tuaj yeem tsim tau siv peev casting tuaj yeem suav nrog cov duab sib txawv, thiab feem ntau cov khoom raug cam khwb cia nyob ze cov duab, yog li yuav tsum tau me me los yog tsis muaj rework ib zaug cam khwb cia.
