Umhleli weprofayili yemaski ye-N95
Imaski e-N95 yenye ye-NIOSH eqinisekisiweyo yokuphefumla ngamasuntswana. ”N” imele ukunganyangeki kwi-oyile. kwinani elichaziweyo lamasuntswana ovavanyo olukhethekileyo. I-95% yala maxabiso ayiyo i-avareji, kodwa i-minimum.I-N95 ayilona igama elithile lemveliso, ukuba nje idibana nomgangatho we-N95 kwaye ivunyiwe yi-NIOSH.Ibakala lokukhusela le-N95 lithetha ukuba ukuhluzwa kakuhle kwezinto zokucoca imaski kwizinto ezingenayo i-oyile (ezifana nothuli, inkungu ye-asidi, inkungu yepeyinti, i-microorganism, njl.) yi-95% phantsi kweemeko zokuvavanya ezichazwe ngumgangatho we-NIOSH.
Umsebenzi nenjongo yokuhlela
Ukusebenza kakuhle kokucoca imaski ye-N95 kumasuntswana anedayamitha ye-aerodynamic ye-0.075 m±0.02 m ngaphezu kwe-95%.I-aerodynamic diameters ye-bacterial and fungal spores esemoyeni yahluka kakhulu phakathi kwe-0.7 kunye ne-10 m kwaye ikwangaphakathi kuluhlu lwemaski ye-N95. Ke ngoko, imaski ye-N95 inokusetyenziselwa ukhuseleko lokuphefumla lwamasuntswana athile, njengokupolisha, ukucocwa kunye nokusetyenzwa kothuli olusuka kwiminerali, umgubo kunye nezinye izinto, njl. ukutshiza, okungavelisi ukuguquguquka okuyingozi
I-gases.Inokucoca ngokufanelekileyo kwaye ihlambulule ivumba elingaqhelekanga eliphefumlelweyo (ngaphandle kweegesi ezinobuthi), kunceda ukunciphisa izinga lokuvezwa kwezinye iincinci ezincinci ze-microbial (ezifana nesikhunta, i-anthrax bacillus, i-bacillus ye-tuberculosis, njl.), kodwa ayisusi umngcipheko wosulelo loqhagamshelwano, ukugula okanye ukufa [1].
Isebe lezabasebenzi lase-US licebise iimaski ezi-N95 kubasebenzi bezempilo ukukhusela kusulelo oluvela emoyeni olufana nomkhuhlane kunye nesifo sephepha.
Umhleli wemigangatho yokhuseleko
Ezinye ii-respirators eziqinisekisiweyo ze-NIOSH ziquka i-N95, i-N99, i-N100, i-R95, i-R99, i-R100, i-P95, i-P99, kunye ne-P100. La manqanaba okukhusela angabandakanya uluhlu lokukhusela lwe-N95.
"N" imele ukunganyangeki kwioli, ifanelekile kwiincinci ezingenayo ioli.
"R" imele i-oyile echasene neoli, ifanele i-oil or non-oily particles. Ukuba isetyenziselwa ukukhusela i-oily particles, ixesha lokusetyenziswa akufanele lidlule iiyure ze-8.
"P" imele ubungqina be-oyile, ilungele i-oily or non-oily particles, ukuba isetyenziselwa i-oily particles, ixesha lokusetyenziswa kufuneka lilandele iingcebiso zomenzi.
"95", "99" kunye "100" zibhekisa kwinqanaba lokuhluza xa uvavanywa nge-0.3 micron.
Ukufaneleka kokujonga umhleli
Ukongeza ekusebenzeni kakuhle kwe-mask, ukuqina phakathi kwe-mask kunye nobuso yenye yezinto ezibalulekileyo ezibonisa ukusebenza kwe-mask. Ngoko ke, ukufaneleka kwe-mask kufuneka kuhlolwe ngaphambi kokusetyenziswa. ubuso bomntu osinxibileyo, qinisekisa ukuba umoya unokudlula ngaphakathi nangaphandle kwesigqubuthelo sobuso phantsi kwemeko yokuvala ngokusondeleyo kumda wobuso.
Uthuli kunye nomhleli wezonyango
UCao xuejun, usekela-mlawuli jikelele wesebe lemveliso yempahla yabathengi kwisebe lezoshishino kunye neteknoloji yolwazi, uthe kwinkomfa yabezindaba ngoLwesibini,
Iimaski ze-N95 ziimaski ezinobuchule bokuhluza ukuya kuthi ga kwi-95%. Zahlulwe zaba ngamacandelo amabini: ukhuseleko lothuli lweshishini kunye nokhuseleko lwezonyango.[2]
"Abasebenzi bapakisha iimaski ezikhuselayo ze-N95 (ifoto ethathwe ngoFebruwari 8) .Kwiintsuku zamva nje, i-shenyang shengshi iteknoloji yezonyango co., LTD., Ukuphela komvelisi weemaski ezikhuselayo ze-N95 kwiphondo elidibeneyo, ubesoloko evelisa ngaphezulu iiyure ezingama-20 ngosuku ukuqinisekisa umthamo wemveliso yemihla ngemihla ngaphezu kwama-20,000 imaski kwiphondo laseHubei kunye nephondo elidibeneyo.[3]
I-Industrial dustproof i-N95 kunye ne-KN95 yi-anti-non-oil particles, kwaye i-N95 yonyango sisiphefumlo sonyango (kungekhona kuphela i-anti - particles, nayo kufuneka ithintele ulwelo, njl. njl.) (umfanekiso okwisihlomelo se
xinhuanet.com yi "N95" kwaye oku kulandelayo "yimaski yokhuseleko lwezonyango")
