Sefa yemhepo
1. Marabhoritari anonyanya kushandiswa kuita microbiology, biomedicine, biochemistry, ongororo yemhuka, genetic recombination, uye zvigadzirwa zvebiology zvakabatanidzwa zvinonzi marabhoritari akachena-biosafety marabhoritari.
2. Iyo biosafety laboratory inoumbwa neiyo huru inoshanda laboratori, mamwe marabhoritari uye ebetsero makamuri anoshanda.
3. Iyo biosafety laboratory inofanirwa kuvimbisa kuchengetedzwa kwemunhu, kuchengetedzwa kwezvakatipoteredza, kuchengetedzwa kwemarara uye sampuli chengetedzo, uye kukwanisa kushanda zvakachengeteka kwenguva yakareba, ichipawo nzvimbo yakagadzikana uye yakanaka yekushanda kune vashandi verabhoritari.
Yakachena kamuri mafirita emhepo akakamurwa zvichienderana nekuita kwesefa (kushanda, kuramba, kubata guruva), kazhinji yakakamurwa kuita coarse-inoshanda mafirita emhepo, yepakati-inoshanda mafirita emhepo, yakakwirira- uye yepakati-inoshanda mafirita, uye sub-yakakwirira-kushanda. mafirita emhepo, High-effective air sefa (HEPA) uye emhando yepamusoro-soro yemhepo sefa (ULPA) marudzi matanhatu emafirita.
Iyo yekusefa nzira inonyanya kusanganisira kubata (kuvheneka), inertial kudhumhana, kupararira kweBrownian uye magetsi akamira.
① Kubata: kuongorora.Zvimedu zvakakura kupfuura mesh zvinopindirwa uye kusefa kunze, uye zvimedu zvidiki pane mesh zvinobuda.Kazhinji, ine mhedzisiro pazvimedu zvakakura, uye kushanda kwacho kwakadzikira, inova nzira yekusefa yemafirita akashata.
② Inertial kudhumhana: zvimedu, kunyanya zvimedu zvakakura, zvinoyerera nemhepo uye zvinofamba zvisina tsarukano.Nekuda kweiyo inertia yezvimedu kana rimwe simba remumunda, dzinotsauka kubva munzira yekuyerera kwemhepo, uye hadzifambi nemhepo, asi inodhumhana nezvipingamupinyi, inonamatira pazviri, uye inosefa kunze.Iyo yakakura iyo particle, iyo yakakura inertia uye yakakwirira kushanda zvakanaka.Kazhinji ndiyo nzira yekusefa yemafirita akakoshera uye ari pakati nepakati.
③ Brownian Diffusion: Zvidiki-diki zviri mumhepo zvinofamba zvisingaite, zvinoroverana nezvipingaidzo, zvinonamirwa nezvikokovonho, uye zvinopepetwa kunze.Iyo diki diki, iyo yakasimba yeBrownian motion, mikana yakawanda yekudhumhana nezvipingamupinyi, uye yakakwirira kugona.Izvi zvinonziwo diffusion mechanism.Iyi ndiyo nzira yekusefa ye-sub-, yepamusoro-inoshanda uye yakanyanya-yepamusoro-soro mafirita.Uye iyo iri pedyo iyo fiber dhayamita iri kune chidimbu dhayamita, zviri nani mhedzisiro.
