1. Kusefa kwakadzama
Rudzi urwu rwemasefa zvinhu haruregereki, uye mukaha uripo pakati pefiber nefiber wakakura.Semuenzaniso, yakajairika polyester inoshongedzwa yakanzwa ine gap ye20-100 μm.Kana avhareji saizi yeguruva iri 1 μm, panguva yekusefa, chikamu chemasefa chinopinda musefa zvinhu uye chosara kumashure, uye chimwe chikamu chinopukunyuka kuburikidza nesefa zvinhu.Huru zhinji inonamatira pamusoro pesefa zvinhu kuti iite sefa layer, iyo inosefa guruva mumhepo ine guruva.Zvimedu zvidiki zvinopinda musefa zvinhu zvichawedzera kuramba uye kuomesa sefa zvinhu kusvika zvaraswa.Rudzi urwu rwekusefa runowanzo kunzi deep filtration.
2. Kusefa pamusoro
Padivi peyakasununguka sefa zvinhu zvinosangana neguruva-ine gasi, chidimbu cheiyo microporous firimu inosungirirwa, uye gaka riri pakati pemafibhi rinongova 0.1-0.2 μm.Kana avhareji yehukuru hwehupfu huchiri 1 μm, inenge yose poda Ichavharwa pamusoro pe microporous membrane, guruva rakanaka harigoni kupinda mukati mesefa zvinhu, iyi nzira yekusefa inowanzonzi surface filtration.Surface filtration ndiyo yakanakira kusefa tekinoroji, inogona kuenderera mberi nekuvandudza kushanda kwekubvisa guruva, kuderedza kurasikirwa kwekumanikidza kwesefa zvinhu, uye kuchengetedza zvakanyanya mashandisirwo emagetsi eiyo guruva rekubvisa system.Kana iyo fiber yefayiri yezvinhu yakaonda kwazvo, mushure mekuita kwakakosha, haingogone kuchengetedza imwe dhigirii yemhepo, asi zvakare kuderedza mukaha pakati pemafibhi.Kunyangwe iyi sefa zvinhu zvisina kuputirwa pamusoro, zvakaoma kuti zvimedu zvakanaka muguruva zvipinde musefa zvinhu.Iri rudzi rwesefa zvinhu zvisina akawanda membranes zvinogona zvakare kushandiswa kusefa pamusoro.Iyo sefa zvinhu zvinoshandiswa kugadzira iyo sefa katuriji, kune akawanda-membrane sefa midhiya uye isiri-yakawanda-membrane sefa midhiya, kuti kusefa kwepamusoro kunogona kuitwa kunoenderana neakasarudzwa sefa zvinhu.
