Isihluzo somoya
1. Iilabhoratri ezisetyenziswa ikakhulu kwi-microbiology, biomedicine, biochemistry, animal experiments, genetic recombination, kunye neemveliso zebhayoloji zibizwa ngokudibeneyo njengeelabhoratri ezicocekileyo-iilebhu zokhuseleko lwendalo.
2. Ilabhoratri ye-biosafety yenziwe yilabhoratri esebenzayo, ezinye iilabhoratri kunye namagumbi ancedisayo.
3. Ilabhoratri ye-biosafety kufuneka iqinisekise ukhuseleko lomntu, ukhuseleko lokusingqongileyo, ukhuseleko lwenkunkuma kunye nokhuseleko lwesampula, kwaye ikwazi ukusebenza ngokukhuselekileyo ixesha elide, ngelixa ibonelela ngendawo yokusebenza ekhululekile kunye nelungileyo kubasebenzi belabhoratri.
Izihluzi zomoya zegumbi ezicocekileyo zahlulwe ngokokusebenza kwesihluzi (ukusebenza, ukuxhathisa, ukubamba uthuli), zihlala zohlulwe ngokwezihluzi zomoya ezirhabaxa, izihluzi zomoya ezinomgangatho ophakathi, izihluzi zomoya eziphezulu kunye neziphakathi, kunye nomgangatho ophantsi. Izihluzi zomoya, Isihluzi somoya esisebenza kakuhle (HEPA) kunye ne-ultra high-effective filter air (ULPA) iintlobo ezintandathu zezihluzi.
Indlela yokucoca ikakhulu ibandakanya ukungenelela (ukuhlola), ukungqubana kwe-inertial, i-Brownian diffusion kunye nombane omileyo.
① Uthintelo: Uvavanyo.Amalungu amakhulu kunomnatha ayabanjwa kwaye ahluzwe ngaphandle, kwaye amasuntswana amancinane kunomnatha avuza.Ngokuqhelekileyo, inempembelelo kumasuntswana amakhulu, kwaye ukusebenza kakuhle kuphantsi kakhulu, okuyindlela yokucoca i-coarse-efficiency filters.
② Ungquzulwano lwe-inertial: amasuntswana, ngokukodwa amasuntswana amakhulu, ahamba kunye nokuhamba komoya kwaye ahamba ngokungaqhelekanga.Ngenxa ye-inertia yamasuntswana okanye amandla athile entsimi, ayaphambuka kwicala lokuhamba komoya, kwaye angahambi kunye nokuhamba komoya, kodwa angqubane nemiqobo, anamathele kuyo, kwaye ahluzwe ngaphandle.Inkulu i-particle, i-inertia enkulu kwaye iphezulu ukusebenza kakuhle.Ngokubanzi yindlela yokucoca yezihluzi ezirhabaxa neziphakathi.
③ I-Brownian Diffusion: Amasuntswana amancinane ekuhambeni komoya enza intshukumo yeBrownian engaqhelekanga, ingqubana nemiqobo, ibambeke ngamagwegwe, kwaye ihluzwe ngaphandle.Incinci i-particle, inamandla intshukumo ye-Brownian, amathuba amaninzi okungqubana nemiqobo, kunye nokusebenza kakuhle.Oku kukwabizwa ngokuba yi-diffusion mechanism.Le yindlela yokucoca ye-sub-, ephezulu-esebenzayo kunye nezihluzo eziphezulu eziphezulu.Kwaye i-fiber diameter isondele kwi-particle diameter, isiphumo esingcono.
