Plaub yam yam ntxwv uas qhia lub pore qauv ntawm sintered hlau porous cov ntaub ntawv

Sintered hlau ntxeem tau cov ntaub ntawv yog dav siv nyob rau hauv ntau yam kev siv xws li pom, sib cais, thiab catalysis. Lub pore qauv ntawm sintered hlau porous cov ntaub ntawv plays lub luag haujlwm tseem ceeb hauv kev txiav txim siab lawv cov kev ua tau zoo.

 

 

Lub pore qauv ntawm sintered hlau ntxeem tau cov ntaub ntawv tuaj yeem ua tau los ntawm ntau yam tsis xws li porosity, pore loj faib, pore zoo, thiab kev sib txuas.

◆ Cov porosity

Porosity txhais tau tias yog ib feem ntawm qhov ntim ntawm cov khoom ntxeem tau uas yog nyob ntawm voids lossis pores. Nws feem ntau yog qhia raws li feem pua. Lub porosity ntawm sintered hlau ntxeem tau cov ntaub ntawv tuaj yeem tswj tau los ntawm kev kho qhov loj, zoo, thiab tus nqi ntawm cov khoom siv hlau siv thaum lub sij hawm sintering.

◆ Pore loj faib

Pore ​​loj faib yog hais txog qhov ntau ntawm qhov pore loj nyob rau hauv cov khoom. Qhov pore loj faib tuaj yeem txiav txim siab siv ntau yam txuj ci xws li mercury porosimetry, gas adsorption, lossis electron microscopy.

◆ Pore puab

Pore ​​zoo kuj tuaj yeem cuam tshuam kev ua haujlwm ntawm sintered hlau porous cov ntaub ntawv. Cov pores tuaj yeem yog kheej kheej, cylindrical, lossis tsis xwm yeem hauv cov duab. Cov duab ntawm qhov pores tuaj yeem cuam tshuam cov dej ntws los ntawm cov khoom siv.

◆ Kev sib txuas

Kev sib txuas yog hais txog qib uas qhov pores sib cuam tshuam. Ib qho kev sib txuas zoo pore qauv tso cai rau cov kua dej zoo dua thiab tuaj yeem txhim kho kev ua haujlwm ntawm cov khoom.
