Imaski yokuhlunga ingxenye yengxenye (6003-2 FFP2)
Ukwakheka kwezinto
Ungqimba lwangaphezulu yindwangu engalukiwe engu-50g.Isendlalelo sesithathu ngu-45g womoya kakotini oshisayo.Isendlalelo sesithathu siyisihlungi se-50g FFP2.Ungqimba lwangaphakathi yindwangu engalukiwe engu-50g.
Imaski ehluza izinhlayiyana ingxenye yesisetshenziswa sokuzivikela esiklanyelwe ukuthi silingane ngokuqinile ebusweni futhi sinqande ukungcola okuphuma emoyeni ekuhogeleni umuntu oyifakile.Lawa madivaysi angabizwa ngokuthi ama-respirator noma ama-FFRs.
Ukusebenza kahle kokuhlunga kungenye yezindlela zokuhlola zokuhlola imaski.
Indlela yokuhlola- Ukusebenza kahle kokuhlunga (FE)
I-FE yinani lezinhlayiya ezitholwa yi-filtration material.Ikalwa ngokuphonsela inselelo okokusebenza ngezinhlayiya zosayizi owaziwayo, ezithwalwa ngezinga lokugeleza elaziwayo noma isivinini, kanye nokulinganisa ukugxiliswa kwezinhlayiyana phezulu nomfula wento, indebe, kanye nomfula ongezansi kokokusebenza, i-Cdown.Ukungena kwe-particle ngokusebenzisa okokuhlunga, i-Pfilter, isilinganiso sokugxiliswa komfula ongezansi kuya ekugxilweni komfula okhuphukayo, ophindwe ngo-100%.I-FE ihambisana nokungena kwezinhlayiyana: FE = 100% - Pfilter.Into yokuhlunga lapho u-5% wezinhlayiya zingena khona (i-Pfilter = 5%) ino-95% FE.I-FE ithonywa yizici eziningi, okuhlanganisa okokuhlunga;usayizi, umumo, kanye nokushajwa kwezinhlayiya zenselele, izinga lokugeleza komoya, izinga lokushisa nomswakama, ukulayisha, nezinye izici.
Kwaziwa kahle ukuthi i-FE yezinto zokuhlunga ingase yehluke ngezinhlayiya ezinosayizi abahlukene kanye nokuma.Lokhu kungenxa yokuthi ukuhlunga kwenzeka ngezinqubo eziningi zomzimba - ukucindezelwa noma ukusefa, ukushayisana kwe-inertial, ukunqamula, ukusabalalisa, ukuhlalisa amandla adonsela phansi, kanye nokukhangwa kwe-electrostatic, futhi ukusebenza kahle kwalezi zinqubo kuyahlukahluka ngosayizi wezinhlayiyana.Usayizi wezinhlayiyana into yokuhlunga ene-FE ephansi kakhulu ubizwa ngokuthi usayizi wezinhlayiyana ongenela kakhulu (MPPS).Ngokufanelekile, i-MPPS isetshenziselwa ukuhlola ukusebenza kokuhlunga, njengoba ukusebenza kahle kwesihlungi kuzo zonke ezinye izinhlayiya kuzoba ngcono kunaleyo etholwe nge-MPPS.I-MPPS iyahlukahluka ngempahla yokuhlunga kanye nesivinini somoya ngesihlungi.Ucwaningo lwangaphambili lubike i-MPPS yama-respirators angu-0.3 μm, kodwa ucwaningo lwakamuva lubonise ukuthi i-MPPS ikububanzi obungu-0.04–0.06 μm.
