Imaski ekhuselayo ye-nanofiber yonyango
Imaski ekhuselayo ye-nanofiber yonyango
Imathiriyeli ekrwada engundoqo , Ulwakhiwo kunye nokwakheka:
Imaski (ubuzali) Yenziwe ngumzimba wemaski, ikliphu yempumlo kunye nebhanti lemaski.Umzimba wemaski wahlulwe: umaleko womphezulu, umaleko wokuhluza, umaleko ocolekileyo wokucoca i-nano, umaleko ongezantsi, umaleko onobubele bolusu, umaleko opheleleyo amahlanu.
Umphezulu, umaleko osezantsi, kunye nolusu olunobuhlobo bemaski yilaphu yePolypropylene espunbonded nonwoven, umaleko wokuhluza lilaphu elingalukwanga lePolypropylene elinyibilikisiweyo, i-nano filtration layer yi-nanofiber membrance, ikliphu yempumlo yenziwe ngezinto zeplastiki, ibhanti yemaski yenziwe nge-polyester kunye ne-spandex yarn.
Isicelo:
Lo mgangatho usebenza kwindawo yokusebenzela yonyango, ukucoca umba we-particle emoyeni, amaconsi ebloko, igazi, ulwelo lomzimba, i-secretions kunye nezinye i-self-absorption filter respirator yonyango.
Iimpawu eziphambili zobugcisa zeemveliso:
Ukusebenza kakuhle kohluzo
Xa izinga lokuhamba kwerhasi liyi-85L/min, ukusebenza kakuhle kokucoca imaski yamasuntswana angeyooli kufuneka kufezekise iimfuno kwitafile.
| Iphepha loku-1,Udidi lohluzo lwempumelelo% | |
| Nye | ≥95 |
| Mbini | ≥99 |
| Ntathu | ≥99.97 |
Ukumelana nokuhamba komoya
Ukuhamba kwegesi ye-85L / min, ukuchasana okuphefumlelweyo kwemaski akufanele kudlule i-343.2pa (35mmH2O)
ukungena kwegazi lokwenziwa
Tshiza i-2mL yegazi lokwenziwa kwimaski ngoxinzelelo lwe-10.7kpa (80mmHg).Akukho kungena kufuneka kwenzeke ngaphakathi kwesigqubuthelo
Ukumelana nokufuma komhlaba
Umgangatho wamanzi kumphezulu wangaphandle wemaski akufanele ube ngaphantsi kwinqanaba le-3 kwi-GB/ t4745-1997
Isalathisi seMicrobiological
Imaski kufuneka ihlangabezane neemfuno zezalathi ze-microbial kwi-gb15979-2002, njengoko kubonisiwe kwitheyibhile 2.
Iphepha lesi-2 Isalathiso seMicrobiological yemaski
| Lilonke inani lee-bacterial colonies CFU/G | coli iqela | pseudomonas aeruginosa | staphylococcus aureus | hemolytic streptococcus | Lilonke inani leekoloni zokungunda |
| ≤200 | ayibonakali | ayibonakali | ayibonakali | ayibonakali | ≤100 |
Intsalela ye-ethylene oxide
Kwiimaski ezihlambulukileyo nge-ethylene oxide, intsalela ye-ethylene oxide akufanele idlule i-10 g / g.
ukumelana nomlilo
Izinto ezisetyenzisiweyo akufanele zitshise.Ixesha lokutshisa emva kokutshisa akufuneki lidlule kwi-5s
Ukucaphuka kwesikhumba
Amanqaku okucaphuka okuphambili kwesixhobo semaski akufuneki adlule
Indlela yokuvala inzala:i-ethylene oxide sterilization.Intsalela ye-ethylene oxide (g/g) ≤10
Umgangatho:GB19083-2010
