Isihlungi somoya
1. Amalabhorethri asetshenziselwa ikakhulukazi i-microbiology, i-biomedicine, i-biochemistry, ukuhlolwa kwezilwane, ukuhlanganiswa kabusha kwezakhi zofuzo, kanye nemikhiqizo yebhayoloji ngokuhlangene kubizwa ngokuthi amalabhorethri ahlanzekile-ama-biosafety laboratories.
2. Ilabhorethri ye-biosafety yakhiwe ilabhorethri esebenzayo eyinhloko, amanye amalabhorethri kanye namakamelo asebenzayo.
3. Ilabhorethri ye-biosafety kufanele iqinisekise ukuphepha komuntu siqu, ukuphepha kwemvelo, ukuphepha kukadoti kanye nokuphepha kwesampula, futhi ikwazi ukusebenza ngokuphepha isikhathi eside, kuyilapho ihlinzeka ngendawo yokusebenza enethezekile nenhle kubasebenzi baselabhorethri.
Izihlungi zomoya zegumbi elihlanzekile zihlukaniswa ngokuya ngokusebenza kwesihlungi (ukusebenza kahle, ukumelana, amandla okubamba uthuli), ngokuvamile zihlukaniswa zibe izihlungi zomoya ezisebenza kahle, izihlungi zomoya ezisebenza kahle kakhulu, izihlungi zomoya ezisebenza kahle kakhulu naphakathi, kanye nokusebenza kahle kakhulu. izihlungi zomoya, Isihlungi somoya esisebenza kahle kakhulu (HEPA) kanye nesihlungi somoya esisebenza kahle kakhulu (ULPA) izinhlobo eziyisithupha zezihlungi.
Indlela yokuhlunga ikakhulukazi ihlanganisa ukucabela (ukuhlola), ukushayisana kwe-inertial, ukusabalalisa kwe-Brownian kanye nogesi omile.
① Ukungena: ukuhlola.Izinhlayiya ezinkulu kunemeshi ziyaxhunywa futhi zihlungwe, futhi izinhlayiya ezincane kunemeshi ziyavuza.Ngokuvamile, inomthelela ezinhlayiyeni ezinkulu, futhi ukusebenza kahle kuphansi kakhulu, okuyindlela yokuhlunga yezihlungi ezisebenza kahle.
② Ukungqubuzana kwangaphakathi: izinhlayiya, ikakhulukazi izinhlayiya ezinkulu, zigeleza nokugeleza komoya futhi zinyakaze ngokungahleliwe.Ngenxa ye-inertia yezinhlayiya noma amandla athile asensimini, ziyachezuka endleleni yokuhamba komoya, futhi azinyakazi nokugeleza komoya, kodwa zingqubuzana nezithiyo, zinamathele kuzo, futhi zihlungwe.I-particle enkulu, i-inertia enkulu futhi iphakamisa ukusebenza kahle.Ngokuvamile kuyindlela yokuhlunga yezihlungi ezisebenza kahle nezimaphakathi.
③ I-Brownian Diffusion: Izinhlayiya ezincane ekugelezeni komoya zenza ukunyakaza okungajwayelekile kwe-Brownian, zingqubuzane nezithiyo, zibhajwe amahhuku, futhi ziyahlungwa.Uma uhlamvu luncane, ukunyakaza kwe-Brownian kunamandla, amathuba amaningi okushayisana nezithiyo, kanye nokusebenza kahle kakhulu.Lokhu kubizwa nangokuthi i-diffusion mechanism.Lena indlela yokuhlunga yezihlungi ezingaphansi, ezisebenza kahle kakhulu nezisezingeni eliphezulu kakhulu.Futhi lapho i-diameter ye-fiber isondela kububanzi bezinhlayiyana, umphumela uba ngcono.
