Kev kho mob folding nanofiber tiv thaiv daim npog qhov ncauj
Kev kho mob folding nanofiber tiv thaiv daim npog qhov ncauj
Main raw khoom, Cov qauv thiab muaj pes tsawg leeg:
Mask (sterility) Nws yog tsim los ntawm lub ntsej muag lub cev, qhov ntswg clip thiab daim npog ntsej muag.Lub ntsej muag lub cev tau muab faib ua: txheej txheej, pom txheej, nplua nano pom txheej, txheej hauv qab, txheej txheej tawv nqaij, tag nrho tsib txheej.
Qhov saum npoo, hauv qab txheej, thiab cov tawv nqaij zoo nkauj txheej ntawm daim npog ntsej muag yog Polypropylene spunbonded nonwoven npuag, pom txheej yog Polypropylene yaj-txhaj tshuaj tsis yog ntaub, zoo nano pom txheej yog nanofiber membrance, lub qhov ntswg clip yog ua los ntawm cov khoom yas, lub npog ntsej muag yog ua los ntawm polyester thiab spandex xov paj.
Daim ntawv thov:
Cov qauv no siv tau rau qhov chaw ua haujlwm kho mob, lim cov khoom me me hauv huab cua, thaiv cov tee dej, ntshav, cov kua hauv lub cev, cov kua dej tso tawm thiab lwm yam kev nqus tus kheej lub tshuab ua pa.
Main technical indicators, As cov khoom:
Filtration efficiency
Thaum cov roj ntws tawm yog 85L / min, qhov pom kev ua haujlwm ntawm lub npog ntsej muag rau cov khoom tsis yog roj yuav tsum ua kom tau raws li qhov yuav tsum tau ua hauv cov lus
| daim 1,Lim efficiency chav kawm% | |
| Ib | ≥95 |
| ob | ≥99 |
| Peb | ≥99.97 |
Airflow kuj
Rau cov roj ntws ntawm 85L / min, qhov inspiratory tsis kam ntawm lub npog ntsej muag yuav tsum tsis pub tshaj 343.2pa (35mmH2O)
hluavtaws ntshav nkag
Txau 2mL ntawm cov ntshav hluavtaws rau hauv lub npog ntsej muag ntawm qhov siab ntawm 10.7kpa (80mmHg).Tsis muaj infiltration yuav tsum tshwm sim hauv daim npog qhov ncauj
Deg noo noo tsis kam
Cov dej nyob rau sab nrauv ntawm lub npog ntsej muag yuav tsum tsis txhob qis dua qib 3 hauv GB / t4745-1997
Microbiological ntsuas
Lub npog ntsej muag yuav tsum ua tau raws li qhov yuav tsum tau ua ntawm cov ntsuas microbial hauv gb15979-2002, raws li qhia hauv cov lus 2
Daim ntawv 2 Microbiological Performance index ntawm daim npog qhov ncauj
| Tag nrho cov kab mob colony CFU/G | coli pab | pseudomonas aeruginosa yog ib yam kab mob | Staphylococcus aureus | hemolytic streptococcus | Tag nrho cov naj npawb ntawm cov kab mob fungal |

Residual ethylene oxide
Rau lub qhov ncauj qhov ntswg sterilized los ntawm ethylene oxide, qhov seem ntawm ethylene oxide yuav tsum tsis pub tshaj 10 g / g.
nplaim tsis kam
Cov ntaub ntawv uas siv yuav tsum tsis txhob o.Lub sijhawm tom qab hlawv yuav tsum tsis pub tshaj 5s
tawv nqaij khaus
Qhov qhab nia rau thawj qhov khaus ntawm daim npog qhov ncauj yuav tsum tsis txhob tshaj
Txoj kev Sterilization:ethylene oxide sterilization.Residual ethylene oxide (g / g) ≤10
