Gusobanukirwa byimbitse ihame ryakazi no gukoresha firime idahumeka

Amazi adahumeka ya firime nigicuruzwa gikomoka kuri tekinoroji yo gutandukanya membrane. Ni firime yakozwe hamwe nuburyo budasanzwe kandi ifite uburyo bwo guhitamo. Irashobora kwemerera imyuka imwe ntoya kurenza aperture ya firime ihumeka idafite amazi kunyura munsi yayo, kandi ntishobora kwemerera ibindi bintu nkibitonyanga byamazi binini kuruta aperture ya firime ihumeka amazi. Ni ukubera neza imiterere ya firime idahumeka amazi niho molekile ntoya ishobora kunyura, na molekile nini nini ntishobora kunyura muri firime ihumeka amazi, bityo kuva mu myaka ya za 1960 yikinyejana gishize, firime ihumeka idafite amazi. Kugeza ubu, hari cyane cyane PTFE, PES, PVDF, PP, PETE nibindi byungurura, kubera imiterere myiza yimiti yibikoresho bya ePTFE, imiterere ya hydrophobique naturel kandi ikoreshwa mubice byose byubuzima.

Ihame ryakazi ryamazi adahumeka neza

Muri reta yumuyaga wamazi, diameter ya molekile ziva mumazi ni microni 0.0004 gusa, naho diameter ntarengwa yibitonyanga byamazi ni microni 20. Kubaho kwa polymer ihumeka irimo micropores muri firime ihumeka idafite amazi ituma molekile ziva mumazi zurukuta zisohoka neza binyuze muri microporome membrane binyuze mumahame yo gukwirakwiza, bikagabanya neza ikibazo cya kondegene kurukuta rwinyuma. Kubera umurambararo munini wamazi yamazi cyangwa ibitonyanga byamazi hanze yurukuta, molekile zamazi ntizishobora kwinjira mumasaro yamazi kurundi ruhande, bigatuma firime ihumeka idafite amazi. ‍

Mubihe bisanzwe, ibikoresho byinshi nibisabwa bisaba ibidukikije bifunze cyane, bidashobora guterwa numukungugu wo hanze, amazi, na bagiteri. Niba igishushanyo gifunzwe cyane, mubihe byubushyuhe bwubushyuhe bwibidukikije hamwe n’imihindagurikire y’imihindagurikire, bizaganisha ku mpinduka z’umuvuduko imbere mu bikoresho, ubusanzwe iri hinduka ry’umuvuduko rizatanga ingaruka zifatika, zizasenya ibice byoroshye byibikoresho bya shell kandi imbere. Imikoreshereze ya ePTFE idafite amazi ihumeka neza irashobora gukomeza guhuza itandukaniro ryumuvuduko wibikoresho, kugabanya igiciro cyibishushanyo mbonera, no kwemeza ko ibicuruzwa byizewe.

ePTFE ibiranga firime ihumeka

Amashanyarazi: 0.1-10μm microhole, aperture iri munsi yinshuro 10,000 10,000 yamasaro yamazi, kugirango amazi adashobora kunyura, kurinda neza ibice byoroshye, kwirinda isuri yamazi, kuzamura ubuzima bwibicuruzwa.

Umwuka wo mu kirere: diameter ya micropore iruta inshuro 700 kurenza imyuka y'amazi, idafite amazi icyarimwe, ituma umwuka ugenda neza, birashobora gushyuha neza, bikarinda urukuta rw'imbere rw'igicu cy'ibicuruzwa, kuringaniza umuvuduko w'imbere mu gihugu no hanze.

Kwirinda umukungugu: Umuyoboro wa microporome ukora meshi yuburyo butatu muri firime, kandi gukwirakwiza hamwe no gukwirakwiza micropore bituma umukungugu uhura nimbogamizi, kugirango bigere ku ngaruka nziza zo gukumira ivumbi, kandi byibuze bishobora gufata 0.1 mm.
