Porous ceramics Txheej txheem cej luam

Thaum nws los txog rau microporous ceramics, peb yuav tsum hais txog porous ceramics ua ntej.

Porous ceramics yog ib yam tshiab ntawm cov khoom siv ceramic, tseem hu ua pore functional ceramics, tom qab kub kub calcination thiab refining, vim hais tias nyob rau hauv lub firing txheej txheem yuav tsim ib tug heev ntxeem tau qauv, yog li nws tseem hu ua ntxeem tau ceramics, yog ib tug loj tus naj npawb ntawm cov khoom. cov ntaub ntawv ceramic nrog kev sib txuas lus los yog kaw qhov pores hauv lub cev.

Classification ntawm porous ceramics

Porous ceramics tuaj yeem raug cais los ntawm qhov loj me, theem muaj pes tsawg leeg thiab pore qauv (pore loj, morphology thiab kev sib txuas).

Raws li qhov pore loj, nws tau muab faib ua: ntxhib porosity ntxeem tau ceramics (pore loj> 500μm), porosity loj porous ceramics (pore loj 100 ~ 500μm), nruab nrab porosity ntxeem tau ceramics (pore loj 10 ~ 100μm), me porosity ntxeem tau ceramics ( pore loj 1 ~ 50μm), nplua porosity ntxeem tau ceramics (pore loj 0.1 ~ 1μm) thiab micro-porosity ntxeem tau ceramics. Raws li tus qauv pore, porous ceramics tuaj yeem muab faib ua cov porous ceramics thiab non-uniform porous ceramics.

Txhais ntawm microporous ceramics

Microporous ceramics yog ib qho pore qauv micro-porosity ntxeem tau ceramics, yog ib hom tshiab ntawm cov khoom siv ceramic, kuj yog ib qho kev ua haujlwm zoo ntawm ceramics, raws li lub npe qhia, yog nyob rau hauv ceramic sab hauv los yog nto uas muaj ntau qhov qhib lossis kaw micro- pores ntawm lub cev ceramic, lub micropores ntawm microporous ceramics yog me me heev, nws qhov aperture feem ntau yog micron lossis sub-micron qib, yog qhov yooj yim pom ntawm qhov muag liab qab. Txawm li cas los xij, microporous ceramics tau pom tseeb hauv lub neej niaj hnub, xws li cov lim dej ceramic siv hauv cov dej lim dej thiab cov tub ntxhais atomization hauv cov luam yeeb hauv hluav taws xob.

Keeb kwm ntawm microporous ceramics

Qhov tseeb, kev tshawb fawb thoob ntiaj teb ntawm microporous ceramics tau pib hauv xyoo 1940s, thiab tom qab ua tiav kev txhawb nqa nws daim ntawv thov hauv kev lag luam mis nyuj thiab dej haus (wine, npias, cider) kev lag luam hauv Fabkis thaum xyoo 1980s, nws pib siv rau kev kho dej phwj thiab. lwm yam teb.

Nyob rau hauv 2004, lub ntiaj teb no ntxeem tau ceramics kev lag luam muag ntim yog ntau tshaj 10 billion US dollars, vim hais tias ntawm kev vam meej daim ntawv thov ntawm microporous ceramics nyob rau hauv precision filtration cais, nws cov lag luam muag ntim ntawm ib xyoos ib zaug kev loj hlob ntawm 35%.

Kev tsim cov microporous ceramics

Cov hauv paus ntsiab lus thiab cov txheej txheem ntawm ntxeem tau ceramics muaj xws li particle stacking, pore ntxiv tus neeg sawv cev, qis kub underfiring thiab mechanical processing. Raws li cov txheej txheem ntawm pore tsim thiab pore qauv, porous ceramics yuav muab faib ua granular ceramic sintered lub cev (microporous ceramics), ua npuas ncauj ceramics thiab honeycomb ceramics.

Microporous ceramics yog ib yam tshiab ntawm inorganic non-metallic lim khoom, microporous ceramics yog tsim los ntawm aggregate particles, binder, pore ntawm 3 qhov chaw, quartz xuab zeb, corundum, alumina (Al2O3), silicon carbide (SiC), mullite (2Al2O3-3SiO2). ) thiab ceramic hais raws li aggregate, tov nrog ib tug npaum li cas ntawm binder, thiab tom qab kub kub firing nrog pore-forming tus neeg sawv cev, aggregate hais, binders, pore-forming agents thiab lawv cov kev sib raug zoo tej yam kev mob txiav txim lub ntsiab yam ntxwv ntawm ceramic pore loj, porosity, permeability. Aggregates, zoo li adhesives, raug xaiv raws li lub hom phiaj ntawm kev siv cov khoom. Nws yog feem ntau yuav tsum tau hais tias lub aggregate muaj lub zog siab, kub tsis kam, corrosion kuj, nyob ze rau lub pob zoo (yooj yim tsim rau hauv cov lim dej), yooj yim granulation nyob rau hauv qhov muab ntau yam, thiab zoo affinity nrog lub binder. Yog hais tias lub substrate aggregate thiab particle loj yog tib yam, lwm yam kev mob yog tib yam, cov khoom lub pore loj, porosity, huab cua permeability qhia tau lub hom phiaj zoo tagnrho.
