Umsebenzi kunye nomgaqo wokhuseleko we-mask ye-KN95 |KENJOY

Yintoni indimaImaski ye-KN95?Yintoni i-Kn95 elahlayo?Luhlobo luni lomgaqo wokukhusela onokudlalwa, ngokulandelayoI-kn95 imaski ethengisa yonke intoukukunika ingcaciso elula.

Indima ye-kn95

Ukusebenza kakuhle kokucoca amasuntswana anedayamitha ye-aerodynamic ≥0.3m inokufikelela ngaphezulu kwe-95% xa unxibe imaski yeklasi ye-KN95.Idayamitha ye-aerodynamic yebhaktiriya esemoyeni kunye ne-fungal spores ihluka kakhulu phakathi kwe-0.7-10m, ekwangaphakathi kuluhlu lokukhusela.

Ngoko ke, i-respirator ingasetyenziselwa ukukhusela ukuphefumla kwamasuntswana athile, njengothuli oluveliswa ngokusila, ukucocwa kunye nokulungiswa kweeminerali, umgubo kunye nezinye izinto, kunye nolwelo okanye amasuntswana angenawo ioyile aveliswa ngokutshiza angavelisi. iigesi eziyingozi eziguquguqukayo.

Ukuhluzwa okusebenzayo kunye nokucocwa kwamavumba aphefumulayo (ngaphandle kweegesi ezinetyhefu), kunceda ukunciphisa amanqanaba okuvezwa kumasuntswana e-microbial anokuphefumla (umzekelo, isikhunta, i-bacillus anthracis, isifo sephepha, njl.), kodwa ayiphelisi ingozi yokudluliselwa koqhagamshelwano, ukugula okanye ukufa.

Inqanaba le-KN95 lelinye lamanqanaba achazwe kumgangatho waseTshayina we-GB2626-2006.

Yintoni imaski ye-KN95 elahlayo

"Ukulahlwa" yinkcazelo yemveliso ngokomgangatho wesizwe, okuthetha ukuba imveliso ayinakucocwa kwaye yonke imveliso kufuneka ilahlwe ngoko nangoko xa naliphi na ilungu lingaphumeleli.Izinto zokuphefumla ziphinda zisetyenziswe kwaye akuyomfuneko ukuba zilahlwe xa sele zisetyenzisiwe.

Iimaski ezilahlwayo ezinokulahlwa naphi na, nanini na, njengoko igama licebisa

Kuba eyona ndawo iyiyo yezixhobo zokuphefumla iyindawo yokusebenzela, kudla ngokuchazwa ukuba izixhobo zokuphefumla zinokutshintshwa emva kweshifti enye yokusebenza, ikakhulu ngenxa yokuba izixhobo zokuphefumla azinakuhlanjwa kwaye abasebenzi akufuneki kufuneke basebenzise iimaski ezingacocekanga.

Nangona kunjalo, zinokuthi zisetyenziswe kwakhona ukuba zisetyenziswe ixesha elifutshane, azikho iingxaki zempilo, kwaye aziyi kusebenza (ezifana nokukhubazeka okanye ukonakala), okanye ukwanda kokumelana nokuphefumula kuphezulu kakhulu.

Umgaqo okhuselayo we-FFP2 imaski

Izinto ezisetyenziselwa ukuhluza i-particulate matter ine-fiber mineral, ifayibha yendalo okanye ifayibha yokwenziwa, ifayibha yezinto zokucoca yahlulwe yaba ziindidi ezintlanu zokucoca umbandela wesuntswana emoyeni, zinokudlala indima ebanzi.

I-Sedimentation: i-particle enkulu kwi-airflow ichaphazeleka yi-gravity sedimentation kwizinto zokucoca, zahlulwe kumoya;

Impembelelo ye-inertia: xa amasuntswana kwibhloko yokudlula komoya phambi kwefiber yezinto zokucoca, umgangatho ophezulu wamasuntswana uya kuphambuka kwicala lokuhamba komoya nge-inertia, ukubetha i-fiber yezinto zokucoca ihluzwe phantsi;

I-Interception: iincinci kwi-airflow isondele kwi-streamline ye-filter material, kuba i-radius ye-particle inkulu kunomgama phakathi kwe-streamline kunye ne-filter material "ikhutshiwe" kwaye ibanjwe yinto yokucoca;

I-Diffusion effect: ichaphazelekayo yintshukumo ye-thermal yee-molecule zomoya, iincinci ezincinci kakhulu ngefuthe leemolekyuli zomoya, zihlala zitshintsha indlela yokuhamba, i-Brownian motion, i-random contact kunye ne-fiber filter ihluzwa phantsi;

Impembelelo ye-Electrostatic: ukuba i-fiber yezinto zokucoca kunye nombane ongenamandla omileyo, nokuba amasuntswana emoyeni ngokwawo anombane omileyo, xa ekufutshane nefiber yezinto zokucoca kulula ukutsalwa ngumbane ongatshintshiyo kwaye ahluzwe ezantsi, isiphumo se-electrostatic nceda izixhobo zokucoca ziphucule ukusebenza kakuhle kokucoca ngaphandle kokunyusa ukumelana nokuhamba komoya

Oku ngasentla yindima ye-mask ye-KN95 kunye nomgaqo wokukhusela wentshayelelo efanelekileyo, ufuna ukwazi ngakumbi malunga nolwazi lwe-FFP2 yemaski, wamkelekile ukuba uqhagamshelane nathi.imaski ethengisa ngevenkile.
