Umhleli wephrofayela yemaski ye-N95
Imaski i-N95 ingesinye seziphefumula eziyisishiyagalolunye eziqinisekisiwe ze-NIOSH.” I-N” imele ukungamelani nowoyela.” enombolweni ethile yezinhlayiya zokuhlola ezikhethekile.95% kulawa manani awawona ama-avareji, kodwa ubuncane.I-N95 ayilona igama elithile lomkhiqizo, inqobo nje uma ihlangabezana nezinga le-N95 futhi igunyazwe yi-NIOSH.Ibanga lokuvikela le-N95 lisho ukuthi ukusebenza kahle kokuhlunga kwesihlungi semaski kuzinhlayiya ezingenawo amafutha (njengothuli, inkungu ye-asidi, inkungu kapende, i-microorganism, njll.) kungu-95% ngaphansi kwezimo zokuhlola ezishiwo izinga le-NIOSH.
Umsebenzi nenjongo ukuhlela
Ukusebenza kahle kokuhlunga kwemaski ye-N95 ezinhlayiyeni ezinobubanzi be-aerodynamic obungu-0.075 m±0.02 m kungaphezu kuka-95%.Ububanzi be-aerodynamic bezinhlamvu zebhaktheriya ezihamba emoyeni kanye nesikhunta ziyahlukahluka kakhulu phakathi kuka-0.7 no-10 m futhi zingaphakathi kwebanga lemaski engu-N95. Ngakho-ke, imaskhi ye-N95 ingasetshenziselwa ukuvikela ukuphefumula kwezinhlayiya ezithile, njengokupholisha, ukuhlanza nokucubungula uthuli oluvela kumaminerali, ufulawa nezinye izinto, njll. ukufafaza, okungakhiqizi i-volative eyingozi
Ingakwazi ukuhlunga futhi ihlanze iphunga elingavamile elihogeliwe (ngaphandle kwamagesi anobuthi), isize ekunciphiseni izinga lokuchayeka kwezinye izinhlayiya ezincane eziphefumulayo (njengesikhunta, i-anthrax bacillus, isifo sofuba, njll.), kodwa ayiqedi ingozi yokutheleleka, ukugula noma ukufa [1].
Umnyango wezabasebenzi waseMelika uncome imaski engu-N95 yabasebenzi bezokunakekelwa kwempilo ukuvikela ezifweni ezitholakala emoyeni ezinjengomkhuhlane nesifo sofuba.
Umhleli wamazinga okuphepha
Ezinye iziphefumulo eziqinisekisiwe ze-NIOSH zifaka i-N95, i-N99, i-N100, i-R95, i-R99, i-R100, i-P95, i-P99, ne-P100. Lawa mazinga okuvikela angamboza ibanga lokuvikela le-N95.
“N” imele ukungamelani nowoyela, ifanele izinhlayiya ezingezona amafutha.
"R" imele amafutha amelana nowoyela, afanele izinhlayiya ezinamafutha noma ezingenawo amafutha. Uma isetshenziselwa ukuvikela izinhlayiya ezinamafutha, isikhathi sokusebenzisa akufanele sidlule amahora angu-8.
“P” imele ubufakazi bamafutha, ifanele izinhlayiya ezinamafutha noma ezingenawo amafutha, uma isetshenziselwa izinhlayiya ezinamafutha, isikhathi sokusebenzisa kufanele silandele izincomo zomenzi.
I-“95″, ”99″ kanye ne-”100″ ibhekisela ezingeni elisebenza kahle lokuhlunga lapho ihlolwa nge-micron engu-0.3
Isihleli sokuhlola ukufaneleka
Ngaphezu kokuphumelela kokuhlunga kwe-mask, ukuqina phakathi kwe-mask nobuso kungenye yezinto ezibalulekile ezinquma ukusebenza kwe-mask. Ngakho-ke, ukufaneleka kwe-mask kufanele kuhlolwe ngaphambi kokusetshenziswa.Lapho kuhlolwa ukuqina kwe-mask. ebusweni bomuntu ogqokile, qinisekisa ukuthi umoya ungangena uphinde uphume kumaski ngaphansi kwesimo sokusondela eduze konqenqema lobuso.
Uthuli nomhleli wezokwelapha
UCao xuejun, iphini likamqondisi jikelele womnyango wemboni yezimpahla zabathengi womnyango wezezimboni nobuchwepheshe bolwazi, uthe esithangamini nabezindaba ngoLwesibili,
Amamaski ama-N95 angamamaski asebenza kahle ngokuhlunga afinyelela ku-95%. Ahlukaniswe abe izigaba ezimbili: ukuvikelwa kothuli lwezimboni kanye nokuvikelwa kwezokwelapha.[2]
"Abasebenzi bapakisha imaski ye-N95 yokuvikela impilo (isithombe esithathwe ngoFebhuwari 8). Ezinsukwini zamuva nje, i-shenyang shengshi medical technology co., LTD., okuwukuphela komkhiqizi womamaski be-Medical-Profection N95 esifundazweni sase-liaoning, ubelokhu ekhiqiza ngaphezu kwalokho. amahora angu-20 ngosuku ukuqinisekisa umthamo wokukhiqiza wansuku zonke wamamaski angaphezu kuka-20,000 wesifundazwe saseHubei kanye nesifundazwe sase-liaoning.[3]
I-Industrialproof N95 kanye ne-KN95 ziyizinhlayiya ezingafaki amafutha, kanti i-N95 yezokwelapha iyisikhuthazi sezokwelapha (hhayi kuphela izinhlayiya ezilwa nothuli, futhi ezidinga ukuvimbela uketshezi, njll.).(isithombe esisesithasiselweni se-
