Ntchito ndi chitetezo cha KN95 mask |KENJOY

Udindo waKN95 mask?Kodi Kn95 yotayika ndi chiyani?Ndi mtundu wanji wa chitetezo chomwe chingaseweredwe, chotsatiraKn95 mask yogulitsakuti ndikufotokozereni mophweka.

Ntchito ya kn95

Kusefera kwa tinthu tating'onoting'ono tokhala ndi aerodynamic ≥0.3m kumatha kufika kupitilira 95% mutavala chigoba cha kalasi ya KN95.Kutalika kwa aerodynamic kwa spores za bakiteriya ndi mafangasi zimasiyanasiyana pakati pa 0.7-10m, zomwe zilinso mkati mwazoteteza.

Chifukwa chake, chopumiracho chingagwiritsidwe ntchito poteteza kupuma kwa tinthu tina tating'ono, monga fumbi lopangidwa ndikupera, kuyeretsa ndi kukonza mchere, ufa ndi zinthu zina, komanso tinthu tating'onoting'ono tomwe timapangidwa ndi kupopera mbewu mankhwalawa. mpweya woipa wosakhazikika.

Kusefa kogwira mtima ndi kuyeretsa fungo lopumira (kupatulapo mpweya wapoizoni), kumathandizira kuchepetsa kukhudzana ndi tinthu tating'onoting'ono tating'ono tating'ono tating'onoting'ono (monga nkhungu, bacillus anthracis, chifuwa chachikulu, ndi zina), koma sikuchotsa chiopsezo chotenga kachilomboka, matenda kapena imfa.

Mulingo wa KN95 ndi umodzi mwamagawo omwe akufotokozedwa mu muyezo waku China GB2626-2006.

Kodi chigoba cha KN95 ndi chiyani

"Zotayidwa" ndi tanthauzo la chinthu chomwe chili mulingo wadziko lonse, zomwe zikutanthauza kuti katunduyo sangathe kutsukidwa ndipo chinthu chonsecho chiyenera kutayidwa nthawi yomweyo chigawo chilichonse chikalephera.Zopumira zimatha kugwiritsidwanso ntchito ndipo siziyenera kutayidwa zikagwiritsidwa ntchito.

Masks otayidwa omwe amatha kutayidwa kulikonse, nthawi iliyonse, monga momwe dzinalo likunenera

Popeza malo opangira makina opumira ndi malo ogwirira ntchito, nthawi zambiri zimanenedwa kuti zopumira zimatha kusinthidwa pambuyo pakusintha kamodzi kogwira ntchito, makamaka chifukwa zopumira sizingatsukidwe ndipo ogwira ntchito sayenera kufunidwa kugwiritsa ntchito masks osayenera.

Komabe, zikhoza kugwiritsidwanso ntchito ngati zakhala zikugwiritsidwa ntchito kwa nthawi yochepa, palibe vuto la thanzi, ndipo sizikhala zopanda mphamvu (monga zopunduka kapena zowonongeka), kapena kuwonjezeka kwa kukana kupuma kumakhala kwakukulu.

Chitetezo cha chigoba cha FFP2

Zinthu zomwe zimagwiritsidwa ntchito posefera tinthu tating'onoting'ono zimakhala ndi michere yamchere, CHIKWANGWANI chachilengedwe kapena CHIKWANGWANI chopangidwa, zosefera zakuthupi zimagawidwa m'mitundu isanu yazinthu zosefera mumlengalenga, zimatha kuchita nawo gawo lonse.

Sedimentation: tinthu tating'onoting'ono tomwe timatuluka mu mpweya umakhudzidwa ndi mphamvu yokoka kuzinthu zosefera, zolekanitsidwa ndi kutuluka kwa mpweya;

Mphamvu ya inertia: pamene tinthu tating'onoting'ono tomwe timatulutsa mpweya wodutsa kutsogolo kwa fiber fiber, mawonekedwe apamwamba a tinthu tating'onoting'ono timapatuka kuchokera kumayendedwe a mpweya ndi inertia, kugunda fiber fiber imasefedwa pansi;

Kuthamangitsidwa: tinthu tating'onoting'ono tomwe timatuluka mumlengalenga ndi pafupi kwambiri ndi mayendedwe azinthu zosefera, chifukwa utali wa tinthu tating'onoting'ono ndi wamkulu kuposa mtunda wapakati pa mtsinjewo ndi zinthu zosefera "zophwanyidwa" ndikulandidwa ndi zinthu zosefera;

Kufalikira kwamphamvu: kukhudzidwa ndi kayendedwe ka matenthedwe a mamolekyu a mpweya, tinthu tating'onoting'ono tomwe timakhudzidwa ndi mamolekyu a mpweya, kusintha komwe kumayendera, kusuntha kwa Brownian, kukhudzana mwachisawawa ndi fiber fiber kumasefedwa pansi;

Electrostatic effect: ngati fyuluta zakuthupi zokhala ndi magetsi ofooka osasunthika, mosasamala kanthu kuti particles mu airflow palokha ndi magetsi osasunthika, pamene ali pafupi ndi fyuluta zakuthupi zimakhala zosavuta kukopeka ndi magetsi osasunthika ndikusefedwa pansi, electrostatic effect ikhoza thandizirani zosefera kupititsa patsogolo kusefa popanda kuwonjezera kukana kwa mpweya

Zomwe zili pamwambazi ndi gawo la chigoba cha KN95 ndi mfundo zoteteza pakuyambitsa koyenera, mukufuna kudziwa zambiri za chigoba cha FFP2, talandilani kuti mulumikizane ndi athu.mask wholesale.
