N95 mask profile edhita
Iyo N95 mask ndeimwe yemapfumbamwe eNIOSH akasimbiswa particle respirators. "N" inomiririra isingamirire mafuta. kunhamba yakatarwa yezvimedu zvebvunzo.95% yezviyero izvi hazvisi zvepakati, asi zvishoma.N95 harisi zita rechigadzirwa chairo, chero bedzi richisangana neN95 chiyero uye rinotenderwa neNIOSH.Giredhi rekudzivirira reN95 rinoreva. kuti kusefa kwemasiki sefa zvinhu pazvinhu zvisina mafuta (senge guruva, mhute yeasidhi, mhute yependi, microorganism, nezvimwewo) i95% pasi pemamiriro ekuyedzwa akataurwa neNIOSH standard.
Basa uye chinangwa kugadzirisa
Iko kusefa kweN95 mask pazvimedu zvine aerodynamic dhayamita ye0.075 m±0.02 m inodarika 95%.Madhayamita aerodynamic emhepo mabhakitiriya uye fungal spores anosiyana zvakanyanya pakati pe0.7 ne10 m uye zvakare ari mukati meiyo N95 mask. Naizvozvo, N95 mask inogona kushandiswa kudzivirira kufema kwezvimwe zvimedu, senge kukwenenzvera, kuchenesa uye kugadzirisa guruva kubva mumaminerari, hupfu uye zvimwe zvinhu, nezvimwewo, yakakodzerawo kune iyo mvura kana isiri-mafuta zvidimbu zvinogadzirwa ne. kupfapfaidza, izvo zvisingabudisi zvinokuvadza zvinoputika
Inogona kusefa uye kuchenesa kunhuhwirira kusingawanzo kufemerwa (kunze kwemagasi ane muchetura), kubatsira kuderedza kuratidzwa kwemamwe ma microbial particles anofema (senge mold, anthrax bacillus, tuberculosis bacillus, etc.), asi haibvisi iyo njodzi yekubata utachiona, kurwara kana kufa [1].

Zvimwe zveNIOSH certified respirators zvinosanganisira N95, N99, N100, R95, R99, R100, P95, P99, uye P100. Aya mazinga ekudzivirira anogona kuvhara nzvimbo yekudzivirira yeN95.
"N" inomiririra isingamiri kumafuta, inokodzera zvimedu zvisina mafuta.
"R" inomirira oiri isingaenderane neoiri, inokodzera mafuta kana asina mafuta. Kana yakashandiswa kudzivirira zvidimbu zvemafuta, nguva yekushandisa haifanirwe kudarika maawa masere.
"P" inomiririra humbowo hwemafuta, inokodzera mafuta kana asina mafuta, kana yakashandiswa kune zvidimbu zveoiri, nguva yekushandisa inofanirwa kutevedzera zvinokurudzirwa nemugadziri.
"95" , "99" uye "100" inoreva chiyero chekusefa kana yakaedzwa ne 0.3 micron.
Kukodzera kutarisa mupepeti
Pamusoro pekushanda kwefiltration yemasikisi, kusimba pakati pemasiki uye chiso ndechimwe chezvinhu zvakakosha zvinogadzirisa kushanda kwemasikisi.Saka, kukodzera kwemasiki kunofanira kuongororwa kusati kwashandiswa. Kumeso kwemupfeki, ita shuwa kuti mweya unogona kupinda nekubuda kunze kwemasiki pasi pemamiriro epedyo kumucheto kwechiso.
