Mask Opaleshoni Kuti Mukwaniritse Miyezoyo Ndizofunikira Zizindikiro

1. Chigoba choteteza kuchipatala
Mogwirizana ndi gb19083-2003 zofunika paumisiri zothandizira kupumulira kwachipatala, zofunikira zaukadaulo zikuphatikiza kusefedwa kogwira ntchito komanso kukana kwa mafunde pazinthu zopanda mafuta:
(1) kusefedwa kolimba: pansi pa kayendedwe ka kayendedwe ka mpweya (85 ± 2) L / min, kusefa bwino kwa mlengalenga wa aerodynamics Median di (0,24 ± 0.06) m sodium chloride aerosol sikuchepera 95%, ndiye kuti, ikugwirizana. mpaka N95 (kapena FFP2) ndi pamwambapa.
(2) Kukana kolimbikitsira: pansi pazinthu zotumphukira pamwambapa, kukondoweza sikuyenera kupitirira 343.2pa (35mmH2O).
 
2. Ma mask opangira opaleshoni
Mogwirizana ndi YY 0469-2004 zofunikira paukadaulo zamasamba opangira opaleshoni, zofunikira zaukadaulo zikuphatikiza kusefedwa koyenera, kukhathamiritsa kwa bakiteriya komanso kukana kupuma:
(1) kusefukira kolimba: pansi pa kayendedwe ka kayendedwe ka mpweya (30 ± 2) L / min, kusefa bwino kwa mawonekedwe aerodynamics Median di (0,24 ± 0,06) m sodium chloride aerosol sikuchepera 30%;
(2) bakiteriya kusefera kabwino: pansi pa zochitika, kusefedwa kwa staphylococcus aureus aerosol ndi tinthu tating'onoting'ono ta (3) 0,3) mita sikotsika ndi 95%;
(3) kukana kupuma: pansi pa mawonekedwe a kusefera kwa kayendedwe kabwino, kukondoweza sikuyenera kupitirira 49Pa, ndipo kukana kwakunja sikuyenera kupitirira 29.4pa.
 
3. Chotupa chachikulu
Malinga ndi zoyenera zogulitsidwa zomwe zalembedwa (YZB), zofunikira pakuzosefera kwa tinthu tokhala ndi mabakiteriya sizikuchepa, kapena kufunika kwa kusefa kwa ma tinthu ndi mabakiteriya ndizotsika poyerekeza ndi zomwe zimapangitsa opaleshoni ndi opumira.
