Chiyambi cha ukadaulo wa microporous ceramics

Fountyl Technologies PTE Ltd imatha kupanga chuck yaporous ceramic vacuum chuck yapamwamba kwambiri, zoumba zaporous, Ceramic chuck, nsalu zotsatsa ndi zowotcha za silicon, zowotcha, zowotcha za ceramic, zowonera zosinthika, zowonera magalasi, matabwa ozungulira ndi zida zosiyanasiyana zosakhala zitsulo.

Porous ceramics mwachidule

Ponena za zoumba zazing'onoting'ono, tiyenera kutchula zadothi zadothi poyamba.

Porous ceramics ndi mtundu watsopano wa zinthu zadothi, wotchedwanso pore ziwiya zadothi, pambuyo mkulu kutentha calcination ndi kuyenga, chifukwa mu kuwombera ndondomeko kupanga porous dongosolo, choncho amadziwikanso kuti porous ceramics, ndi chiwerengero chachikulu cha porous ceramics. zida za ceramic zomwe zimalumikizana kapena kutsekedwa pores m'thupi.

Kugawika kwa porous ceramics

Zoumba za porous zitha kugawidwa kuchokera ku kukula, mawonekedwe a gawo ndi kapangidwe ka pore (kukula kwa pore, morphology ndi kulumikizana).

Kutengera kukula kwa pore, imagawidwa kukhala: zoumba zolimba (pore kukula> 500μm), zoumba zazikulu za pore (kukula kwa pore 100 ~ 500μm), zoumba zapakatikati (pore kukula 10 ~ 100μm), zoumba zazing'ono zadothi ( pore kukula 1 ~ 50μm), zabwino porosity porous ceramics (pore kukula 0.1 ~ 1μm) ndi yaying'ono porosity porous ceramics. malinga ndi kapangidwe ka pore, zoumba za porous zitha kugawidwa m'magulu adothi adothi adothi ndi zoumba zosafanana.

Tanthauzo la microporous ceramics

Microporous ceramics ndi yunifolomu pore dongosolo yaying'ono-porosity porous ziwiya zadothi, ndi mtundu watsopano wa zinthu zadothi, ndi zinchito structural ziwiya zadothi, monga dzina likunenera, ali mu ceramic mkati kapena pamwamba munali ambiri kutsegula kapena kutseka yaying'ono- pores a thupi la ceramic, ma micropores a microporous ceramics ndi ochepa kwambiri, kabowo kake kamakhala kakang'ono kakang'ono kapena kakang'ono ka micron, kwenikweni sawoneka ndi maso. Komabe, zoumba zazing'ono zazing'ono zimawonekera m'moyo watsiku ndi tsiku, monga zosefera za ceramic zomwe zimagwiritsidwa ntchito mu chotsukira madzi ndi phata la atomization mu ndudu yamagetsi.

Mbiri ya microporous ceramics

M'malo mwake, kafukufuku wapadziko lonse lapansi pazadothi za microporous zidayamba m'ma 1940, ndipo atatha kulimbikitsa ntchito yake mumakampani a mkaka ndi zakumwa (vinyo, mowa, cider) ku France kumayambiriro kwa zaka za m'ma 1980, zidayamba kugwiritsidwa ntchito pochizira zimbudzi ndi zakumwa zoziziritsa kukhosi. magawo ena ofanana.

Mu 2004, dziko porous ziwiya zadothi msika malonda voliyumu ndi oposa 10 biliyoni US madola, chifukwa ntchito bwino zadothi microporous mu mwatsatanetsatane kusefera kulekana, malonda ake msika voliyumu pa chaka kukula mlingo wa 35%.

Kupanga ma microporous ceramics

Mfundo ndi njira za porous ceramics zikuphatikizapo particle stacking, pore add agent, low kutentha underfiring and mechanical processing. Malinga ndi njira yopangira pore ndi pore, zoumba za porous zitha kugawidwa m'magulu ang'onoang'ono a ceramic sintered body (microporous ceramics), thovu zadothi ndi zisa zadothi.

Micramics yophika ndi mtundu watsopano wa invoroganic zinthu zopanda zosefera, zopondera zophatikizika, nyemba, nulucn carbide (2), 3ssio2 ) ndi particles ceramic monga akaphatikiza, wothira kuchuluka kwa binder, ndipo pambuyo kutentha kuwombera ndi pore kupanga wothandizila, akaphatikiza particles, binders, pore-kupanga wothandizila ndi mikhalidwe yawo chomangira kudziwa makhalidwe chachikulu cha ceramic pore kukula, porosity, permeability. Aggregates, monga zomatira, amasankhidwa malinga ndi cholinga cha ntchito mankhwala. Nthawi zambiri pamafunika kuti aggregate ikhale ndi mphamvu zambiri, kukana kutentha, kukana dzimbiri, pafupi ndi mawonekedwe a mpira (osavuta kupanga muzosefera), granulation yosavuta mkati mwa kukula kwake, komanso kuyanjana bwino ndi chomangira. Ngati akaphatikiza gawo lapansi ndi tinthu kukula ofanana, zinthu zina ndi zofanana, mankhwala pore kukula, porosity, mpweya permeability zizindikiro angathe kukwaniritsa cholinga chabwino.
