Imaski evikela i-nanofiber yezokwelapha
Imaski evikela i-nanofiber yezokwelapha
Impahla eluhlaza eyinhloko, Isakhiwo kanye nokwakheka:
Imaski (ubunyumba) Yakhiwe ngomzimba wemaski, isiqeshana sekhala kanye nebhande lemaski.Umzimba wemaski uhlukene: ungqimba olungaphezulu, ungqimba lokuhlunga, ungqimba oluhle lokuhlunga lwe-nano, ungqimba olungezansi,Isendlalelo esinobungani besikhumba, isamba sezingqimba ezinhlanu.
Ingaphezulu, ungqimba olungezansi, kanye nongqimba lwemaski oluhambisana nesikhumba luyindwangu engalukiwe ye-Polypropylene ephothiwe, ungqimba lokuhlunga yindwangu engalukiwe encibilikisiwe ye-Polypropylene, ungqimba oluhle lokuhlunga lwe-nano luyi-nanofiber membrance, isiqeshana sekhala senziwe ngezinto zepulasitiki,Ibhande lemaski eyenziwe nge-polyester nentambo ye-spandex.
Isicelo:
Leli zinga lisebenza endaweni yokusebenza yezokwelapha, hlunga i-particle emoyeni, amaconsi e-block, igazi, uketshezi lomzimba, uketshezi kanye nezinye izihlungi zokuphefumula ezizibambayo.
Izinkomba zobuchwepheshe eziyinhloko zemikhiqizo:
Ukusebenza kahle kokuhlunga
Lapho izinga lokugeleza kwegesi lingu-85L/min, ukusebenza kahle kokuhlunga kwemaski yezinhlayiya ezingezona amafutha kufanele kuhlangabezane nezidingo ezikuthebula.
| ishidi 1,Isigaba sokuphumelela kokuhlunga % | |
| Eyodwa | ≥95 |
| ezimbili | ≥99 |
| Ezintathu | ≥99.97 |
Ukumelana nokugeleza komoya
Ngokugeleza kwegesi okungu-85L/min, ukumelana nokuphefumula kwemaski akufanele kudlule ku-343.2pa (35mmH2O)
ukungena kwegazi okokwenziwa
Fafaza u-2mL wegazi lokwenziwa kumaski ngengcindezi engu-10.7kpa (80mmHg).Akukho ukungena okufanele kwenzeke ngaphakathi kwemaski
Ukumelana nomswakama ongaphezulu
Izinga lamanzi endaweni engaphandle yemaski akufanele libe ngaphansi kwezinga 3 ku-GB/t4745-1997
Inkomba ye-Microbiological
Imaski kufanele ihlangabezane nezidingo zezinkomba ze-microbial ku-gb15979-2002, njengoba kukhonjisiwe kuthebula 2.
Ishidi 2 Inkomba ye-Microbiological yemaski
| Isamba senani lamakoloni amagciwane I-CFU/G | coli iqembu | i-pseudomonas aeruginosa | i-staphylococcus aureus | i-hemolytic streptococcus | Isamba senani lamakoloni fungal |
| ≤200 | akubonakali | akubonakali | akubonakali | akubonakali | ≤100 |
I-ethylene oxide esele
Kumaski afakwe inzalo nge-ethylene oxide, insalela ye-ethylene oxide akufanele ibe ngaphezu kuka-10 g/g.
ukumelana nelangabi
Izinto ezisetshenziswayo akufanele zishise.Isikhathi se-afterburn akufanele sidlule ama-5
Ukucasuka kwesikhumba
Isikolo sokucasuka okuyinhloko kwempahla yemaski akufanele seqe
Indlela yokuvala inzalo:ukukhishwa kwe-ethylene oxide.I-ethylene oxide esele (g/g) ≤10
Okujwayelekile:I-GB19083-2010
