Medical kupindana nanofiber chitetezo chigoba
Main zopangira, Kapangidwe ndi kapangidwe:
Chigoba (kubereka) Chimapangidwa ndi chigoba thupi, mphuno kopanira ndi chigoba lamba.Thupi la chigoba limagawika: pamwamba, kusefera, kusanjikiza bwino nano, pansi, wosanjikiza khungu, magawo asanu.
Pamwamba, wosanjikiza pansi, ndi wosanjikiza khungu wokonda chigoba ndi Polypropylene spunbonded nonwoven nsalu, kusefera wosanjikiza ndi Polypropylene kusungunula-opopera nonwoven nsalu, chabwino nano kusefera wosanjikiza ndi nanofiber membrance, kopanira mphuno yopangidwa ndi zinthu pulasitiki, Chigoba lamba ndi zopangidwa ndi polyester ndi spandex thonje.
Ntchito:
Muyezo uwu umagwira ntchito kumalo ogwirira ntchito zachipatala, zosefera zomwe zili mumlengalenga, madontho a block, magazi, madzi am'thupi, zotulutsa ndi zina zopumira zodziyimira pawokha.
Zizindikiro zazikulu zaukadaulo wazogulitsa:
Kusefera bwino
Kuthamanga kwa gasi kukakhala 85L/mphindi, kusefa kwa chigoba kwa tinthu tating'ono ting'onoting'ono kuyenera kukwaniritsa zofunikira patebulo.
| pepala 1,Gulu la kusefera % | |
| Mmodzi | ≥95 |
| awiri | ≥99 |
| Atatu | ≥99.97 |
Kukana kwa mpweya
Pakuyenda kwa mpweya wa 85L / min, kukana kolimbikitsa kwa chigoba sikuyenera kupitirira 343.2pa (35mmH2O)
kupanga magazi kulowa
Uza 2mL ya magazi opangidwa mu chigoba ndi kuthamanga kwa 10.7kpa (80mmHg).Palibe kulowetsedwa kuyenera kuchitika mkati mwa chigoba
Pamwamba kukana chinyezi
Madzi akunja kwa chigoba sayenera kukhala otsika kuposa 3 mu GB/t4745-1997
Chizindikiro cha Microbiological
Chigobachi chiyenera kukwaniritsa zofunikira za zizindikiro za tizilombo toyambitsa matenda mu gb15979-2002, monga momwe tawonetsera pa tebulo 2.

Zotsalira ethylene oxide
Kwa masks osawilitsidwa ndi ethylene oxide, zotsalira za ethylene oxide siziyenera kupitirira 10 g/g.
kukana moto
Zida zomwe zimagwiritsidwa ntchito zisapse.Nthawi yowotcha siyenera kupitirira 5s
Kukwiya pakhungu
Kuchuluka kwa kuyabwa koyambirira kwa zinthu za chigoba kuyenera kupitilira
Njira yotsekera:ethylene oxide sterilization.Ethylene oxide yotsalira (g/g) ≤10
Standard:GB19083-2010
