ffp2 imaski vs pm2.5 |KENJOY

Nokuba sijongene nobhubhane wehlabathi jikelele okanye imililo yasendle eyintlekele ebangela umsi orekhodiweyo kunye nongcoliseko lomoya, kuncinci okwaziwayo ngomahluko phakathiffp2 iimaskikunye ne-particulate filter pm2.5 imaski.Zombini iimaski zeFFP2 kunye neemaski ezinamasuntswana anezihluzi ze-pm2.5 zibonelela ngokhuseleko olugqwesileyo kumasuntswana amancinci emoyeni.Zombini iimaski ze-ffp2 kunye ne-PM2.5 zilungele ukulwa amasuntswana amakhulu ngokungonwabi kancinci.Kufuneka isetyenziswe nini enye yezi, ngakumbi xa umboneleli wezempilo efuna isixhobo sokuphefumla?

FFP2 imaski

Iimaski ze-FFP2 ziluncedo kwizibhedlele, ii-ofisi zoogqirha nakwezinye iindawo apho iintsholongwane ezihamba emoyeni zixhaphakile.Iimaski ze-FFP2 zifanelekile ekuthinteleni ulwelo lomzimba oluqulethe ibhaktheriya kunye neentsholongwane ukuba ziphume emzimbeni wakho, kodwa zingangeni emzimbeni wakho.Ngokubanzi, iimaski ze-ffp2 ziyilelwe ukukhusela abantu abakungqongileyo ngokunciphisa amasuntswana omoya emlonyeni wakho nasempumlweni, kubandakanya ii-virion ezibetha kulwelo lomzimba wakho.

Kuba iimaski ze-ffp2 ziyilelwe ukuvala amathontsi amanzi, zihlala zikhululekile kwaye zinokushiya umsantsa phakathi komphetho wemaski kunye nolusu lwakho.Nangona amathontsi anzima kakhulu kungenakwenzeka ukuba ahambe aye kumda wemaski, ezi zithuba zenza imaski ingasebenzi kakuhle ekuthinteleni uhlaselo lwamasuntswana amancinane, alula anokuthi atyibilike kwizikhewu ezininzi phakathi kwemaski yeffp2 kunye nobuso bakho.

Imaski yento ethile

Ikwaziwa njengeemaski ze-PM2.5, zingena ngcono kuneemaski ze-ffp2 kwaye zihlala ziphinda zisetyenziswe.Nangona kunjalo, ngokungafaniyo neemaski ze-ffp2, iimaski ze-"PM 2.5" ziyilelwe ukukhusela wena nabanye, ngoko zikholisa ukulingana ngcono, zinemibimbi embalwa, kwaye zinokuqulatha (ezihluziweyo) iivalvu eziphefumlayo.Ezi maski zidla ngokupakishwa ngezihluzo ezilahlwayo eziyi-2.5.Kuxhomekeka "kwibakala" lezi maski, zinokuyilwa ukuba zihluze i-65% ukuya kwi-90% yamasuntswana e-aerosol acocekileyo, angaphantsi nje kancinci kuneemaski ze-N95, kodwa ngoxinzelelo oluphantsi lokufunxa.

Iintlobo ezahlukeneyo zeemaski zeFFP2 zisebenzisa izixhobo zokucoca ezahlukeneyo.Ngakolunye uhlangothi, i-filtration effect ihambelana nobukhulu be-particle, kodwa iphinda ichaphazeleke nokuba iinqununu ziqukethe ioli okanye cha.Iimaski zeFFP2 zihlala zihlelwa ngokwendlela yokucoca kunye nokuba zikulungele na ukuhluza amasuntswana anamafutha.Amasuntswana angenawo ioyile afana nothuli, inkungu esekelwe emanzini, inkungu yepeyinti, umsi ongenawo ioli (umsi we-welding), ii-microorganisms, njl. , njengenkungu yeoli, i-oil fume, i-asphalt fume, umsi we-oven ye-coke kunye nokunye.Izinto zokucoca ezilungele iinqununu ezinamafutha zingasetyenziselwa iincinci ezingenayo i-oyile.

Zeziphi iimaski ze-ffp2 ezifanelekileyo

1. Iimveliso zokukhusela zomntu ezenzelwe ukukhusela okanye ukunciphisa ukungena kothuli oluvela emoyeni kwizitho zokuphefumla zomzimba womntu ukwenzela ukukhusela ukhuseleko lobomi.

2. Izinto eziphathekayo: iimaski ezichasene ne-particulate ubukhulu becala zenziwe ngezaleko zangaphakathi nangaphandle zelaphu elingalukwanga kunye nombindi welaphu lokucoca (ilaphu elivuthelweyo elinyibilikayo).

3. Umgaqo wokuhluza: ukuhluza uthuli olucolekileyo ikakhulu kuxhomekeke kwilaphu lokucoca phakathi.Ngenxa yokuba ilaphu elinyibilikayo lineempawu zalo zombane ongatshintshiyo, liyakwazi ukufunxa amasuntswana amancinane ngokusebenzayo.Ngenxa yokuba uthuli lufakwe kwisihluzo sokuqala, kwaye isihluzo sokuqala asikwazi ukuhlanjwa ngombane ongatshintshiyo, isihluzi sokuphefumla se-self-priming anti-particulate kufuneka sitshintshwe rhoqo.

4. Iinkcazo: ukusetyenziswa kweemaski ezichasene ne-particulate kungqongqo kakhulu kwihlabathi.Iimaski ze-anti-particulate zezenqanaba lokuqala kwizixhobo zokukhusela zomntu, eziphezulu kuneendlebe kunye neeglasi zokukhusela.Izatifikethi zovavanyo ezigunyazwe ngakumbi sisiqinisekiso se-CE eYurophu kunye nesatifikethi se-NIOSH e-United States, ngelixa umgangatho e-China ufana naleyo ye-NIOSH e-United States.

5. Izinto ezikhuselayo: izinto ezikhuselayo yi-KP kunye ne-KN.I-KP ebizwa ngokuba yi-KP inokukhusela i-oily and non-oily particles, ngelixa i-KN inokukhusela kuphela i-oily particles.

Oku kukwaziswa kwe-ffp2 imaski vs pm2.5.Ukuba ufuna ukwazi ngakumbi malunga neemaski zeFFP2, nceda uzive ukhululekile ukuqhagamshelana nathi.
