Yintoni FFP2 imaski |KENJOY

Awunakuphuma ngaphandle kokunxiba imaski, kodwa yintoni abantu abaninzi abayaziyo ngabo?Oku kulandelayo yinkcazo yeIimaski zeFFP2ngomthengisi weemaski.

Enyanisweni, i-European standard FFP2 imaski, enye ye-EN149: imigangatho ye-2001, sisixhobo sokukhusela esilahlwayo sonyango esinobuncinci bokucoca ukusebenza kakuhle kwe-94% okanye ngaphezulu kwaye sinokuvala i-aerosols eyingozi ngaphandle kokuphefumlelwa.Imaski ye-FFP2 yeza kwindawo yesibini, kunye nenqanaba eliphezulu yiFFP3 (ngaphantsi kwe-97 yepesenti yokuhluza) kwaye ibakala eliphantsi libe yi-FFP1 (ukuhluzwa okuncinci).

Isetyenziselwa ntoni iFFP2

1. Amanqaku okhuseleko lomntu enzelwe ukukhusela okanye ukunciphisa uthuli emoyeni ekungeneni kwizitho zokuphefumula zomntu, ukwenzela ukukhusela ukhuseleko lobomi;

2, imathiriyeli: imaski echasene nesuntswana ubukhulu becala isebenzisa iileya ezimbini zelaphu elingalukwanga ngaphakathi nangaphandle, umaleko ophakathi welaphu lokucoca (ilaphu elivuthelweyo) isakhiwo;

3, umgaqo wokuhluza: ukuhluzwa kothuli olucolekileyo ikakhulu kuxhomekeke kumbindi welaphu lokucoca, kuba ilaphu elinyibilikayo lineempawu ze-electrostatic, linokufunxa amasuntswana alungileyo.Ngenxa yokubhengezwa kothuli kwinto yokucoca, into yokucoca ayinakucocwa ngombane ongatshintshiyo, kwaye into yokucoca kufuneka itshintshwe rhoqo.

4. Qaphela: Ukusetyenziswa kweemaski zothuli ekhaya nakwamanye amazwe kungqongqo kakhulu, phakathi kwayo i-anti-particle mask ikwinqanaba lokuqala, eliphakamileyo kuneendlebe kunye neeglasi zokukhusela.Isiqinisekiso sovavanyo esigunyazisiweyo sinesiqinisekiso se-CE yaseYurophu kunye ne-United States yesatifikethi se-NIOSH, kunye nomgangatho we-NIOSH wase-United States uyafana.

5. Izinto zokukhusela: Izinto zokukhusela zihlulwe zibe yi-KP kunye ne-KN, i-KP iyakwazi ukukhusela i-oily kunye ne-oily particles, ngelixa i-KN ikwazi ukukhusela kuphela iincinci ezingenayo i-oily.

I-6, ibakala lokukhusela: Ibakala lokukhusela laseChina lahlulwe kwi-KP100, KP95, KP90 kunye ne-KN100, KN95, KN90.Phakathi kwabo, i-KP100 kunye ne-KN100 inokusebenza okuphezulu kokucoca okungaphezulu kwe-99.97% ngokomgangatho wesizwe, ngoko banokhuseleko oluphezulu lokusetyenziswa.

Khetha indlela

1. isiphumo sokugquma uthuli silungile.Ukusebenza kokuthintela uthuli lwemaski kusekwe kwimpumelelo yokuthintela ngokuchasene nothuli olucolekileyo, ngakumbi uthuli oluphefumla phantsi kwe-5μm.Umgaqo wokuthintela uthuli lwemaski ye-gauze yi-filtration yomatshini, oko kukuthi, xa uthuli kunye ne-gauze zingqubana, ezinye iinqununu ezinkulu zothuli ziya kuvala umaleko ngomqolo.Kodwa uthuli oluhle, ngakumbi uthuli olungaphantsi kwe-5μm, ludlula kwi-mesh ye-gauze kwaye lungene kwinkqubo yokuphefumula.Kwimarike yokuthengisa, kukho izinto ezininzi zokucoca ezinombane ongatshintshiyo osisigxina, izinto zokucoca yifayibha equlethe umbane ongatshintshiyo osisigxina, uthuli oluphefumlayo olungaphantsi kwe-5 microns ngale nto yokucoca, itsalwa ngumbane ongatshintshiyo, i-adsorption kwizinto zokucoca, ngenene ukudlala indima ekuthinteleni uthuli.

2. imaski kunye nokumila kobuso kufutshane nenqanaba lokulungileyo.Kuba imaski ayinxibelelani ngokusondeleyo nobuso, uthuli oluqhutywa ngumoya luya kungena kwindlela yomoya ngezithuba ezijikeleze imaski.Ke ngoko, abantu kufuneka bakhethe imaski echasene nesuntswana ngokuhambelana nobume babo, kwaye banxibe imaski yothuli ngokufanelekileyo.

3. ukunxiba ngokukhululekileyo, kubandakanywa ukuchasana nokuphefumla okuncinci, ubunzima obulula, ukunxiba impilo, ukugcinwa okufanelekileyo, njengokunxiba i-arch anti-particulate mask.

Oku ngasentla kukwazisa ngokufutshane kweemaski zeFFP2.Ukuba ufuna ukwazi ngakumbi malunga nemaski, nceda uqhagamshelane nathiumthengisi wemaski zonyango.Sikholelwa ukuba uya kufumana impendulo eyanelisayo.
