1. Dulani tinthu ting'onoting'ono ta fumbi mumlengalenga, yendani ndikuyenda mopanda mphamvu kapena kusuntha kwa Brownian mwachisawawa kapena kusuntha ndi mphamvu yakumunda. Kusuntha kwa particle kukagunda zinthu zina, mphamvu ya van der Waals imakhalapo pakati pa zinthu (mamolekyu ndi mamolekyu, Mphamvu pakati pa gulu la molekyulu ndi gulu la molekyulu imapangitsa kuti tinthu tizikhala pamwamba pa ulusi. mpweya umakhala wosasunthika.
2. Inertia ndi Diffusion Fumbi la tinthu ting'onoting'ono limayenda mu inertia mu mpweya. Mukakumana ndi ulusi wosalongosoka, kutuluka kwa mpweya kumasintha njira, ndipo tinthu tating'onoting'ono timamangidwa ndi inertia, yomwe imagunda ulusi ndikumangika. Kukula kwa tinthu, ndikosavuta kukhudza, komanso zotsatira zake zabwino. Fumbi laling'ono laling'ono limagwiritsidwa ntchito poyenda mwachisawawa. Tizigawo tating'onoting'ono tating'onoting'ono, kusuntha kosasinthika kwambiri, kumakhala ndi mwayi wogunda zopingazo komanso zotsatira zosefera. Tinthu ting'onoting'ono ting'onoting'ono 0,1 micron mumlengalenga amagwiritsidwa ntchito makamaka pakuyenda kwa Brownian, ndipo tinthu tating'onoting'ono tating'ono komanso kusefa ndikwabwino. Tinthu tating'onoting'ono topitilira 0,3 ma microns amagwiritsidwa ntchito kwambiri poyenda mopanda mphamvu, ndipo tinthu tating'onoting'ono timakhala tambiri. Sizodziwikiratu kuti kufalikira ndi inertia ndizovuta kwambiri kusefa. Poyezera magwiridwe antchito a zosefera zapamwamba kwambiri, nthawi zambiri zimatchulidwa kuti ziwerengedwe zafumbi zomwe zimakhala zovuta kuyeza.
3. Electrostatic action Pazifukwa zina, ulusi ndi tinthu tating'onoting'ono titha kuyimbidwa ndi mphamvu yamagetsi. Kusefera kwa zinthu zosefera zoyendetsedwa ndi electrostatic kumatha kuwongolera kwambiri. Chifukwa: Magetsi osasunthika amapangitsa fumbi kusintha njira yake ndikugunda chopinga. Magetsi osasunthika amapangitsa fumbi kumamatira kwambiri pa sing'anga. Zida zomwe zimatha kunyamula magetsi osasunthika kwa nthawi yayitali zimatchedwanso zida za "electret". Kukaniza kwa zinthu pambuyo pa magetsi osasunthika sikunasinthe, ndipo zotsatira zosefera zikuwonekera bwino. Magetsi osasunthika sakhala ndi gawo lalikulu pakusefera, koma amangogwira ntchito yothandiza.
4. Kusefera kwa Chemical Zosefera za mankhwala makamaka zimatengera mamolekyu owopsa a mpweya. Pali ma micropores ambiri osawoneka m'zinthu za carbon activated, zomwe zimakhala ndi malo akuluakulu adsorption. Mu adamulowetsa mpweya wa mpunga tirigu kukula, dera mkati micropores ndi oposa khumi lalikulu mamita. Pambuyo pa mamolekyu aulere akhudzana ndi mpweya wopangidwa ndi mpweya, amasungunuka kukhala madzi mu micropores ndikukhalabe mu micropores chifukwa cha mfundo ya capillary, ndipo ena amaphatikizidwa ndi zinthuzo. Adsorption popanda kuchitapo kanthu kwambiri kwamankhwala kumatchedwa thupi adsorption. Zina mwa carbon activated zimathandizidwa, ndipo tinthu tating'onoting'ono ta adsorbed timachita ndi zinthuzo kupanga chinthu cholimba kapena mpweya wopanda vuto, womwe umatchedwa Huai adsorption. Kuthekera kwa ma adsorption a carbon activated pakugwiritsa ntchito zinthu kumafowoka mosalekeza, ndipo ikafooketsedwa pamlingo wina, fyulutayo imachotsedwa. Ngati ndi kutengeka kwa thupi kokha, mpweya woyendetsedwa ukhoza kupangidwanso ndi kutentha kapena kutentha kuti muchotse mpweya woipa mu carbon activated.
