Yintoni umahluko phakathi kweemaski ezilahlayo kunye neemaski zonyango?


1. Iipropathi ezahlukileyo: iimaski ezilahlayo zenziwe ngamacangca amabini kwilaphu elingelilo elingu-28 g. Imaski yezonyango yenziwa ubukhulu becala enye okanye ezingaphezulu zeelaphu ezingalukwanga.

2. Iinkqubo ezahlukileyo: Iinkqubo eziphambili zemveliso yeemaski zonyango zibandakanya i-meltblown, spunbond, umoya oshushu okanye i-acupuncture, njl. Njl. Ezinokuphikisa ulwelo, ukuhluza iinkcukacha kunye neebacteria, kwaye ziindwangu zokhuselo zonyango. Imaski elahliweyo enomaleko emithathu yenziwa ngamacwecwe amabini eefayibha ezingalukanga, ezisetyenziselwa unyango, kunye nolongezo oluphakathi olucoca ngaphezu kwe-99% yengubo ye-bactericidal kunye ne-welding ye-ultrasonically.

3. Isiphumo sahlukile: phantsi kwemeko yokuhamba komoya (85 ± 2) L / min, imaski yezonyango inefilitha esebenza kakuhle engekho ngaphantsi kwe-95% kububanzi be-aerodynamics (0.24 ± 0.06) μm sodium chloride aerosol , ehambelana ne-N95 (okanye i-FFP2) nangaphezulu. Ngaba unokuthi uthintele ukosuleleka ngumoya ngenxa yomoya oyi-5mm ubukhulu okanye uqhagamshelo olusondeleyo kunye nezinto zokusuleleka okuthathwa ngamachaphaza. Imaski ezilahlayo azenzi.
