  • Particle kusefa hafu yemasiki chidimbu chemudziyo wekudzivirira wakagadzirirwa kunyatsokwana kumeso uye kudzivirira zvinosvibisa zvinofambiswa nemhepo kubva mukufemerwa nemunhu akapfeka.Midziyo iyi inogona kudaidzwa kunzi respirator kana kusefa facepiece respirators (FFRs).

    Kushanda kwesefa ndiyo imwe yenzira dzekuyedza yekuongorora mask.

    Kuedza nzira- Kusefa kunyatsoita (FE)
    FE chikamu chezvikamu zvinobatwa nefiltration material.Inoyerwa nekupikisa zvinhu nezvimedu zvesaizi inozivikanwa, inotakurwa pamwero unozivikanwa wekuyerera kana kukurumidza, uye kuyera chiyero chechikamu kumusoro kwechinyorwa, Mukombe, uye zasi kwechinyorwa, Cdown.Particle kupinda mukati mesefa zvinhu, Pfilter, ndiyo chiyero cheiyo yakadzika rwizi yekudzika kusvika kune yakakwira yekumisikidza, yakapetwa ne100%.FE ndiyo mubatsiri we particle kupinda: FE = 100% - Pfilter.Sefa zvinhu izvo 5% yezvimedu zvinopinda (Pfilter = 5%) ine 95% FE.FE inopesvedzerwa nezvakawanda zvinhu, kusanganisira iyo sefa zvinhu;saizi, chimiro, uye kubhadharisa kwezvimedu zvinonetsa, mwero wekuyerera kwemhepo, tembiricha uye hunyoro, kurodha, uye zvimwe zvinhu.

    Zvinonyatsozivikanwa kuti iyo FE yemasefa zvinhu inogona kusiana kune zvimedu zvehukuru hwakasiyana uye maumbirwo.Izvi zvinodaro nekuti kusefa kunoitika kuburikidza nemaitiro akawanda emuviri - kudzvanya kana kusefa, inertial kupindira, kupindira, kupararira, kugadzirisa kwegiravhiti, uye kukwezva kwemagetsi, uye kushanda kwemaitiro aya kunosiyana nekukura kwechikamu.Saizi yechidimbu ine sefa ine yakaderera FE inonzi yakanyanya kupinza particle size (MPPS).Sezvineiwo, iyo MPPS inoshandiswa kuyedza kusefa kuita, sezvo kusefa kwesefa kwezvimwe zvimedu kunenge kuri nani pane kunowanikwa neMPPS.MPPS inosiyana nekusefa zvinhu uye kumhanya kwemhepo kuburikidza nesefa.Zvidzidzo zvepakutanga zvakashuma MPPS yemafemu e0.3 μm, asi ongororo dzichangobva kuitika dzakaratidza kuti MPPS iri muchikamu che 0.04-0.06 μm.
