polymeric membrane rau kev sib cais
Polymeric membrane rau kev sib cais yog daim nyias nyias uas ua los ntawm cov ntawv polymer lossis cov polymer sib xyaw nrog cov kev ua haujlwm ntawm kev sib cais cov kua dej sib xyaw. Membrane sib cais yog nyob ntawm kev xaiv permeability ntawm daim nyias nyias. Qhov sib cais membrane tau siv raws li txheej txheej ntau. Raws li lub zog tsav ntawm qhov sib txawv ntawm qhov siab, qhov txawv ntawm qhov sib txawv, lossis lub peev xwm sib txawv, cov khoom sib xyaw hauv cov dej sib xyaw ua ke nkag rau daim nyias nyias ntawm cov nqi sib txawv kom nws ob tog sib xyaw kom ua tiav lub hom phiaj ntawm kev sib cais, kev ua kom huv, siab thiab rov ua dua tshiab. Tus nqi ntawm cov kua dej mus dhau ntawm daim nyias nyias ib ntu sijhawm (permeation tus nqi), qhov sib piv ntawm permeability coefficient ntawm cov tshuaj sib txawv (sib cais coefficient), lossis qhov tsis lees txais ntawm qee yam khoom yog qhov ntsuas tseem ceeb rau kev ntsuas kev ua haujlwm ntawm daim nyias nyias.
