Kev Siv Thiab Cov Khoom Ntawm Hlau Ua Npuas Ncauj
Mar 06, 2022
Nws muaj huab cua permeability siab, yuav luag tag nrho cov pores txuas nrog, qhov loj tshwj xeeb ntawm qhov pores, thiab cov khoom siv me me.
Hlau ua npuas ncauj yog siv rau hauv kev tsim cov purification, pom, catalytic txhawb, electrodes thiab lwm yam khoom siv hauv petrochemical, aerospace, thiab kev tiv thaiv ib puag ncig.
Piv nrog rau cov hlau sintered ntxeem tau dav, cov khoom siv hlau uas muaj npuas pores muaj qhov porosity ntau dua thiab qhov pore loj dua, txog li 7 hli. Txij li cov hlau ua npuas ncauj yog ob-theem sib xyaw cov khoom tsim los ntawm cov hlau matrix pob txha pob txha txuas ntxiv mus thiab lub pore dispersed theem lossis ntu ntu, nws cov khoom nyob ntawm cov hlau matrix siv, porosity thiab pore qauv, thiab cuam tshuam los ntawm cov txheej txheem kev npaj. Feem ntau, cov khoom siv hluav taws xob ntawm cov hlau ua npuas dej txo nrog qhov nce ntawm porosity, thiab nws cov hluav taws xob conductivity thiab thermal conductivity kuj txo exponentially. Thaum cov hlau ua npuas dej yog nyob rau hauv siab, vim muaj zog ntau zog cheeb tsam thiab cov khoom strain hardening nyhuv tshwm sim los ntawm lub cev qhuav dej ntawm lub pores, cov hlau ua npuas ncauj muaj zoo heev cuam tshuam lub zog nqus cov yam ntxwv.
Hlau ua npuas ncauj yog siv rau hauv kev tsim cov purification, pom, catalytic txhawb, electrodes thiab lwm yam khoom siv hauv petrochemical, aerospace, thiab kev tiv thaiv ib puag ncig.
