* Makhalidwe ochotsa fumbi a cartridge ya fyuluta

1. Kusefera mozama

Zosefera zamtunduwu zimakhala zotayirira, ndipo kusiyana pakati pa ulusi ndi ulusi ndi waukulu.Mwachitsanzo, wamba poliyesitala singano anamva ndi kusiyana 20-100 μm.Pamene pafupifupi tinthu kukula fumbi ndi 1 μm, pa ntchito kusefa, mbali ya particles zabwino adzalowa m'zinthu fyuluta ndi kukhala m'mbuyo, ndi mbali ina adzathawa mwa zinthu fyuluta.Fumbi lochuluka limamatira pamwamba pa zinthu zosefera kuti lipange chigawo cha fyuluta, chomwe chidzasefa fumbi mu mpweya wodzaza fumbi.Tizigawo tating'ono tomwe timalowa muzosefera timawonjezera kukana ndikuumitsa zinthu zosefera mpaka zitachotsedwa.Sefa yamtunduwu nthawi zambiri imatchedwa kusefera kwakuya.

2. Kusefa pamwamba

Kumbali ya zinthu zotayirira zosefera zomwe zimalumikizana ndi mpweya wokhala ndi fumbi, filimu ya microporous imamangiriridwa, ndipo kusiyana pakati pa ulusi ndi 0.1-0.2 μm yokha.Ngati pafupifupi tinthu kukula fumbi akadali 1 μm, pafupifupi onse ufa adzakhala otsekedwa padziko nembanemba microporous, fumbi chabwino sungalowe mkati mwa zinthu fyuluta, njira kusefa nthawi zambiri amatchedwa padziko kusefera.Kusefedwa kwapamwamba ndiukadaulo wabwino wosefera, kumatha kupititsa patsogolo mphamvu yakuchotsa fumbi, kuchepetsa kutayika kwa zinthu zosefera, ndikupulumutsa kwambiri mphamvu yochotsa fumbi.Ngati ulusi wa zinthu zosefera ndi woonda kwambiri, pambuyo pa ndondomeko yapadera, sungathe kukhalabe ndi mpweya wokwanira, komanso kuchepetsa kusiyana pakati pa ulusi.Ngakhale zinthu zoseferazi sizinakutidwe pamwamba, zimakhala zovuta kuti tinthu tating'onoting'ono tafumbi tilowe muzosefera.Zosefera zamtunduwu popanda nembanemba zingapo zitha kugwiritsidwanso ntchito kusefera pamwamba.Zosefera zomwe zimagwiritsidwa ntchito popanga katiriji ya fyuluta, pali zosefera zamitundu yambiri komanso zosefera zopanda ma membrane ambiri, kaya kusefera kwapamtunda kungachitike kutengera zomwe zasankhidwa.
