Iimaski zotyando ezilahlwayo ezifakwe i-ethylene oxide
Iimaski zotyando lwezonyango ziimaski ezilahlwayo ezinxitywa ngabasebenzi bezonyango ngexesha lemisebenzi ehlaselayo, enokuthi igqume umlomo kunye nempumlo yomsebenzisi kwaye ibonelele ngomqobo womzimba ukuthintela ukungena ngokuthe ngqo kwe-pathogens, i-microorganisms, ulwelo lomzimba kunye namasuntswana.
Iimaski zotyando lwezonyango zenziwe ikakhulu ngepolypropylene.Le micu egqwesileyo enesakhiwo esikhethekileyo se-capillary yonyusa inani kunye nommandla womphezulu wefiber kwindawo nganye yeyunithi, ngaloo ndlela yenza amalaphu anyibilikayo anokuhluzwa kakuhle kunye neempawu zokukhusela.

IiMaski zoBuso boNyango eziKhuselekileyo nezisebenzayo
Imaski yonyango yenziwe ngumzimba wobuso bemaski kunye nebhanti loxinzelelo.Umzimba wobuso bemaski wohlulwe ngokwemigangatho emithathu: umaleko wangaphakathi yimathiriyeli ehambelana nolusu (iyasuyasu eqhelekileyo okanye ilaphu elingalukwanga), umaleko ophakathi ngumaleko wokucoca wedwa (ifayibha ye-polypropylene enyibilikayo evuthelweyo. ), kwaye umaleko wangaphandle ngumaleko okhethekileyo we-antibacterial (ilaphu elingalukiweyo okanye i-ultra-thin polypropylene melt-blown material layer).

I-Facemask ye-4ply engalukwanga eLahliweyo ye-KF94 ye-Facemask enezirhintyela zendlebe ezihlengahlengiswayo
Imaski ye-KF94 ngumgangatho owenziwe yimveliso yaseKorea, kwaye yaziwa ngobuchule bayo obukhethekileyo bokucoca.Ngaphantsi kwalo mgangatho, imaski inereyithi yokucoca engaphezulu kwe-94% yamasuntswana anobubanzi be-0.4 μm.
Ngokunxiba imaski ye-KF94, unokunciphisa umngcipheko wokunxibelelana ngokuthe ngqo namathontsi anamasuntswana ayingozi.Imaski yenza umqobo womzimba othintela la mathontsi ukuba adibane nomgudu wakho wokuphefumla.Oku kunceda ekugqibeleni ekunciphiseni amathuba osulelo olunokwenzeka kunye nokusasazeka kweentsholongwane.
