  • Particle sefa theka la chigoba ndi chidutswa cha zida zodzitetezera zomwe zimapangidwira kuti zigwirizane bwino ndi nkhope ndikuletsa zowononga zoyendetsedwa ndi mpweya kuti zisakokedwe ndi wovalayo.Zipangizozi zitha kutchedwa respirator kapena filtering facepiece respirators (FFRs).

    Kuchita bwino kwa kusefera ndi imodzi mwa njira zoyesera zowunikira chigoba.

    Njira yoyesera- Kusefera bwino (FE)
    FE ndi gawo la tinthu tating'onoting'ono tomwe timalandidwa ndi zinthu zosefera.Imayesedwa ndi kutsutsa zakuthupi ndi tinthu tating'onoting'ono todziwika bwino, timanyamula pamlingo wodziwika bwino kapena liwiro, ndikuyesa tinthu tating'onoting'ono tomwe timatulutsa, Cup, ndi kunsi kwa zinthuzo, Cdown.Kulowa kwa tinthu kudzera muzosefera, Pfilter, ndiye chiŵerengero cha ndende ya kunsi kwa mtsinje mpaka kumtunda kwa mtsinje, kuchulukitsa ndi 100%.FE ndiye chothandizira kulowa kwa tinthu: FE = 100% - Pfilter.Zosefera zomwe 5% ya tinthu tating'onoting'ono timalowera (Pfilter = 5%) ili ndi 95% FE.FE imakhudzidwa ndi zinthu zingapo, kuphatikiza zosefera;kukula, mawonekedwe, ndi kuchuluka kwa tinthu zovuta, kuchuluka kwa mpweya, kutentha ndi chinyezi, kutsitsa, ndi zina.

    Ndizodziwika bwino kuti FE ya zinthu zosefera imatha kusiyanasiyana pamagulu amitundu yosiyanasiyana komanso mawonekedwe.Izi ndichifukwa choti kusefera kumachitika kudzera m'njira zingapo zakuthupi - kusefa kapena kusefa, kugunda kwa inertial, kutsekereza, kufalikira, kukhazikika kwamphamvu yokoka, ndi kukopa kwamagetsi, ndipo mphamvu ya njirazi imasiyana ndi kukula kwa tinthu.Kukula kwa tinthu komwe fyulutayo ili ndi FE yotsika kwambiri imatchedwa kukula kolowera kwambiri (MPPS).Momwemo, MPPS imagwiritsidwa ntchito kuyesa magwiridwe antchito, popeza kusefa kwa tinthu tating'onoting'ono tating'onoting'ono kudzakhala bwinoko kuposa komwe kumapezeka ndi MPPS.MPPS imasiyanasiyana ndi zinthu zosefera komanso kuthamanga kwa mpweya kudzera pa fyuluta.Kafukufuku wakale adanenanso kuti MPPS yopumira ya 0.3 μm, koma kafukufuku waposachedwa wasonyeza kuti MPPS ili mu 0.04-0.06 μm.
