Izici zobuchwepheshe ze-KN95|KENJOY

Manje ekuphileni kwethu kwansuku zonke, kufanele sigqoke imaski nomaphi lapho siya khona, kodwa cishe asazi okuningi ngayoKN95 imaski.Namuhla,abahlinzeki bemaski singenise ulwazi oluyisisekelo lwamamaski e-KN95.

Umthombo ojwayelekile

I-KN95 imaskhi ejwayelekile yaseShayina, okuwuhlobo lwemaski esebenza kahle ngokuhlunga izinto ezithile ezweni lethu.Imaski ye-KN95 kanye ne-N95 masks empeleni ziyefana ngokuya ngokusebenza kahle kokuhlunga kwezinhlayiyana.

I-KN95 iyimaski ejwayelekile yaseShayina, evela ku-GB 2626-2019 kazwelonke ejwayelekile ye-GB 2626-2019 "Imishini Yokuphefumula Yokuzivikela Ephefumulayo Isihlungi Se-Anti-particulate Respirator".Leli zinga liyindinganiso likazwelonke eliyimpoqo e-China, elibekwe phambili Ukuphathwa Kwezwe Lokuvikeleka Kwasemsebenzini futhi ngaphansi kwamandla eKomiti Likazwelonke Lobuchwepheshe Lokujwayela Kwemishini Yokuzivikela Ngayodwa (SAC/TC 112).

Izinga lobuchwepheshe

Ngokombono wobubanzi bokusebenza, leli zinga lisebenza ezintweni ezijwayelekile zokuzilungiselela nokuzihluza ukuze kuvikelwe zonke izinhlobo zezinhlayiya, njengamamaski, ezinye izindawo ezikhethekile (ezifana nemvelo ene-anoxic, ukusebenza ngaphansi kwamanzi, njll. ) akusebenzi.

Kusukela encazelweni ye-particle matter, leli zinga lichaza izinhlobo ezihlukahlukene ze-particle, okuhlanganisa uthuli, intuthu, inkungu nama-microorganisms, kodwa alichazi usayizi we-particle.

Ngokweleveli yesici sokuhlunga, ingahlukaniswa izigaba ezimbili: isihlungi sezinhlayiya ezinganamafutha i-KN nokuhlunga izinto ezinamafutha nezingenayo amafutha i-KP, futhi usebenzise lokhu njengophawu, olufana nesandla esingu-N kanye ne-R _ P ecaciswe kumhlahlandlela wokuhumusha we-CFR 42-84-1995.

Izindaba ezidinga ukunakwa

Kuyaphawuleka ukuthi i-GB 2626-2006 "Isihlungi Sokuphefumula Esivikela Ukuphefumula esiziphefumulelayo I-Anti-particulate respirator" isizosebenza, ithathela indawo inguqulo yayo entsha ye-GB 2626-2019 "Isihlungi Sokuvikela Ukuphefumula esizibambayo" esikhishelwe umphakathi wonke uMnyango Wezokuphatha Wemakethe Nokuphatha ngomhla ka-31 Disemba 2019, futhi sizosetshenziswa ngokusemthethweni ngoJulayi 1, 2020. Izinga elisha libekwa phambili futhi labekwa phambili Umnyango Wokuphathwa Kwezimo Eziphuthumayo.

Njengamanje, umbhalo wezinga elisha ushicilelwe futhi wenziwa watholakala kuwo wonke umphakathi mahhala njengendinganiso eyisibopho.Izinga elisha lihambisana namatemu ayisikhombisa njengokuthi "usayizi wezinhlayiyana ze-aerodynamic" futhi lilungisa ezinye izidingo zobuchwepheshe nezindlela zokuhlola, kodwa aliguquli ukuhlelwa, ukumaka nokusebenza kahle kokuhlunga okubalwe kuleli phepha.

I-N95 iyindinganiso yaseMelika

Imaski engu-N95 ingenye yezinhlobo ezingu-9 zamamaski okuzivikela aqinisekiswe yi-NIOSH (Isikhungo Sikazwelonke Sokuphepha Nezempilo Emsebenzini, Isikhungo Sikazwelonke Sokuphepha Nezempilo Emsebenzini).I-N95 akulona igama elithile lomkhiqizo, inqobo nje uma ihlangabezana nezinga le-N95 futhi umkhiqizo ophumelele ukubuyekezwa kwe-NIOSH ungabizwa ngokuthi imaski ye-N95, engakwazi ukuhlunga izinhlayiya ezinobubanzi be-aerodynamic obungu-0.075 μ m ±0.020 μ m nge ukusebenza kahle kokuhlunga okungaphezu kwama-95%.

Okungenhla isingeniso sobuchwepheshe se-KN95.Sidinga ukwazi okwengeziwe ngamamaski e-FFP2.Sicela ukhululeke ukuxhumana nathiimaski factoryukuze uthole iseluleko.
