Kwivuza kwa nanofiber kurinda mask
Kwivuza kwa nanofiber kurinda mask
Ibikoresho nyamukuru, Imiterere nibigize:
Mask (sterility) Igizwe numubiri wa mask, clip yizuru n'umukandara wa mask.Umubiri wa mask wagabanijwe: urwego rwo hejuru, urwego rwo kuyungurura, urwego rwiza rwa nano rwungurura, urwego rwo hasi, urwego rwinshuti rwuruhu, ibice bitanu byose.
Ubuso, igice cyo hasi, hamwe nuruhu rwinshuti rwa mask ni Polypropilene yazungurutswe imyenda idoda, urwego rwo kuyungurura ni Polypropylene yashonga-yatewe imyenda idoda, icyuma cyiza cya nano ni filozofiya ya nanofiber, clip yizuru ikozwe mubintu bya plastiki, Umukandara wa mask ni bikozwe muri polyester na spandex.
Gusaba:
Ibipimo ngenderwaho birakoreshwa mubikorwa byubuvuzi, gushungura ibintu byumuyaga mukirere, guhagarika ibitonyanga, amaraso, amazi yumubiri, ururenda nubundi buryo bwo kwishira muyungurura ubuhumekero bwubuvuzi.
Ibipimo byingenzi bya tekiniki byibicuruzwa:
Gukora neza
Iyo umuvuduko wa gazi ari 85L / min, uburyo bwo kuyungurura mask kubice bitarimo amavuta bigomba kuba byujuje ibisabwa mumeza
| urupapuro 1，Icyiciro cyo gukora neza | |
| Imwe | ≥95 |
| bibiri | ≥99 |
| Bitatu | ≥99.97 |
Kurwanya umwuka
Kuri gazi ya 85L / min, imbaraga zo guhumeka za mask ntizigomba kurenga 343.2pa (35mmH2O)
amaraso yinjira
Shira 2mL yamaraso yubukorikori muri mask kumuvuduko wa 10.7kpa (80mmHg).Nta gucengeza bigomba kubaho imbere ya mask
Kurwanya ubushuhe bwo hejuru
Urwego rwamazi hejuru yinyuma ya mask ntirugomba kuba munsi yurwego rwa 3 muri GB / t4745-1997
Ikimenyetso cya Microbiologiya
Mask igomba kuba yujuje ibisabwa byerekana ibipimo bya mikorobe muri gb15979-2002, nkuko bigaragara mu mbonerahamwe ya 2
Urupapuro 2 Microbiologiya yerekana mask
| Umubare wuzuye wa koloni CFU / G. | itsinda rya coli | pseudomonas aeruginosa | staphylococcus aureus | hemolytic streptococcus | Umubare wuzuye wa koloni |
| ≤200 | kutamenyekana | kutamenyekana | kutamenyekana | kutamenyekana | ≤100 |
Okiside ya Ethylene isigaye
Kuri masike yatewe na okiside ya Ethylene, ibisigisigi bya okiside ya Ethylene ntibigomba kurenza 10 g / g
Kurwanya umuriro
Ibikoresho byakoreshejwe ntibigomba gutwikwa.Igihe cyo gutwika ntigomba kurenza 5s
Kurwara uruhu
Amanota yo kurakara yibanze yibikoresho bya mask ntagomba kurenza
Uburyo bwo kuboneza urubyaro:Ethilene oxyde sterilisation.Okiside ya Ethylene isigaye (g / g) ≤10
Bisanzwe：GB19083-2010
