Dab tsi yog qhov cuam tshuam ntawm kev ntsuas porosity ntawm kev ua haujlwm ntawm ePTFE membrane?

1. Cua permeability:
Lub porosity ntawm ePTFE membrane ncaj qha cuam tshuam rau nws cov huab cua permeability. Qhov siab dua qhov porosity, qhov zoo dua cov huab cua permeability, uas ua rau ePTFE membrane tseem ceeb hauv kev siv xws li huab cua pom, tsis muaj dej thiab ua pa.
2. Pom tseeb:
Qhov pore loj thiab porosity sib koom ua ke txiav txim siab qhov tseeb ntawm ePTFE membrane. Kev ntsuas ntawm porosity tuaj yeem pab txiav txim siab cov qauv microporous ntawm daim nyias nyias thiab yog li ntsuas nws cov nyhuv pom.
3. Barrier kev ua tau zoo:
Lub porosity ntawm ePTFE daim nyias nyias kuj cuam tshuam rau nws txoj kev ua haujlwm tsis zoo. Hauv cov ntawv thov xws li kev lim dej, plua plav thiab dej tsis zoo, qhov porosity tsim nyog tuaj yeem thaiv cov khoom thiab cov kua dej kom zoo thaum tso cov pa nkag mus.
4. Mechanical zog:
Lub porosity ntawm ePTFE daim nyias nyias muaj qhov cuam tshuam loj rau nws lub zog txhua yam. Kev hloov pauv hauv porosity cuam tshuam rau kev taw qhia ntawm cov fibers thiab kev sib txuas ntawm cov nodes, yog li cuam tshuam rau lub zog tensile ntawm daim nyias nyias.
5. Tshuaj stability thiab kub tsis kam:
Kev ntsuas ntawm porosity pab kom nkag siab txog cov tshuaj lom neeg ruaj khov thiab kub tsis kam ntawm ePTFE membrane. Thaum tuav cov tshuaj zoo heev ruaj khov thiab kub tsis kam ntawm PTFE, lub pore qauv ntawm ePTFE membrane muab cov khoom siv ntxiv.
6. Nto khoom:
Qhov pore loj faib, qhov nruab nrab pore loj thiab qhov siab tshaj qhov pore loj ntawm ePTFE membrane, nrog rau cov khoom nto ntawm PTFE, yog cov khoom tseem ceeb tshaj plaws ntawm daim nyias nyias hauv daim ntawv thov. Kev ntsuas ntawm porosity yog qhov tseem ceeb heev rau kev ntsuas qhov ntsuas uas txhais tau tias lub membrane.
7. Tswj cov qauv microporous:
Kev ntsuas ntawm porosity tuaj yeem pab tswj cov qauv microporous ntawm ePTFE daim nyias nyias, uas yog qhov tseem ceeb rau kev ua tiav qhov kev xav tau hauv ib daim ntawv thov tshwj xeeb. Piv txwv li, nyob rau hauv kev siv roj-dej sib cais daim ntawv thov, siab sib cais efficiency thiab flux yuav tau los ntawm kev tswj porosity thiab pore loj.
8. Cov nyhuv ntawm kev kho cua sov:
Kev kho cua sov tuaj yeem cuam tshuam qhov porosity ntawm ePTFE membrane, yog li cuam tshuam rau nws qhov kev ua tau zoo. Cov kev tshawb fawb tau pom tias qhov siab tshaj qhov pore loj, qhov nruab nrab qhov pore loj thiab porosity ntawm cov cua sov kho ePTFE membrane raug txo, thiab tus nqi khaws cia ntawm nanoparticles raug tshem tawm hauv cov kuab tshuaj organic yog ze rau 100%.
