Kutheni le nto isatifikethi se-ffp2 kunzima kangaka ukusifumana|KENJOY

Ukongeza kwimirhumo ephezulu yovavanyo, iindawo zovavanyo eYurophu, ixesha elide lenkqubo kunye nezinye izinto, imigangatho yovavanyo engqongqo ithintele abavelisi bemaski abaninzi.EzilandelayoFFP2 imaski uvavanyo lwempumelelo yokuhluza kunye novavanyo lokumelana nokuphefumla njengemizekelo ukubonisa umgangatho ophezulu wovavanyo.

Inkcazo esemgangathweni ye-FFP2 yokukhusela iziphefumlo zokukhusela

Zombini iimaski ezikhuselayo zaseYurophu naseMelika zonyulwe ukuba zivavanywe yiAmerican TSI-8130Automated Filter Testers izixhobo.I-American standard class N isebenzisa indlela ye-NaCl, iklasi R isebenzisa indlela ye-DOP, kwaye umgangatho waseYurophu usebenzisa indlela ye-DOP.Uvavanyo lwaseYurophu lusebenzisa ioli ye-DOP ukuvelisa uthuli.Ububanzi be-oyile ye-DOP yi-0.33 μ m, i-avareji ye-avareji yokulinganisa i-0.20 μ m, kunye nokusebenza kakuhle kokucoca kufuneka kungabi ngaphantsi kwe-94%.Ngakolunye uhlangothi, i-filtration effect ihambelana nobukhulu be-particle, ngaphezu koko, iphinda ichaphazeleke nokuba iinqununu ziqukethe ioli okanye cha.

Ukongeza, imigangatho yovavanyo lokuphefumla ye-EU ye-FFP2 iziphefumli nayo ingqongqo kakhulu.Uvavanyo lokumelana nokuphefumula lusebenzisa izinga lokuhamba kwe-95L / min kunye novavanyo lokumelana nokuphelelwa yisikhathi lisebenzisa izinga lokuhamba kwe-160L / min.Ubuchule obunjalo bokuhluza obungqongqo kunye nemigangatho yokumelana nokuphefumla yenza abavelisi abaninzi babuyele phantsi ngokuthe ngqo.

Izinto ezintsha ze-nano-end-high-end

Imigangatho yovavanyo engqongqo yokusebenza kakuhle kokucoca kunye nokumelana nokuphefumla kwenza iimaski zeFFP2 zineemfuno eziphezulu zezixhobo zokucoca.Ukusebenza kokucoca kuye kwavavanywa yi-DEKRA ukuba idlule i-96%.Ikhusela impilo yabantu ngokucoca kunye nokuthintela ukungena kwezinto ezinobungozi ezifana namasuntswana othuli, iibhaktheriya, iintsholongwane kunye namasuntswana anamafutha emoyeni.I-surface morphology ye-nano-material entsha yi-spider-web-like microporous structure, into eguquguqukayo kunye ne-elastic microporous ene-porosity ephezulu, ukusabalalisa ubungakanani bepore efanayo, ukungena komoya kunye nokungena kwamanzi.Ngelo xesha, nayo inomsebenzi wokuphefumula ukuqinisekisa ukukhululeka kokugqoka.Isixhobo sisixhobo sokusebenza okuphezulu kunye nokumelana nobushushu obuphezulu, ukumelana nokugqwala, ukuqina okuphezulu kunye namandla, kunye nokuhambelana kakuhle kwe-biocompatibility.I-fiber kunye nobukhulu be-pore ye-nano-material ikwinqanaba le-nanometer, kwaye inokuthintela ngokuthe ngqo ibhaktheriya, iintsholongwane kunye nothuli ngesenzo somqobo womzimba.

Kungenxa yoko le nto isatifikethi se-ffp2 kunzima ukusifumana.Ukuba ufuna ukwazi ngakumbi malunga neemaski zeffp2, nceda uzive ukhululekile ukuqhagamshelana nathi.
