Zosefera mpweya
1. Malo opangira ma laboratories omwe amagwiritsidwa ntchito makamaka popanga tizilombo toyambitsa matenda, biomedicine, biochemistry, kuyesa kwa nyama, kuyanjananso kwa majini, ndi zinthu zamoyo zonse zimatchedwa ma laboratories oyera-biosafety laboratories.
2. Laboratory ya biosafety imapangidwa ndi labotale yayikulu yogwira ntchito, ma laboratories ena ndi zipinda zothandizira.
3. Laboratory ya biosafety iyenera kutsimikizira chitetezo chaumwini, chitetezo cha chilengedwe, chitetezo cha zinyalala ndi chitetezo cha zitsanzo, ndikutha kugwira ntchito motetezeka kwa nthawi yayitali, komanso kupereka malo abwino ndi abwino ogwira ntchito kwa ogwira ntchito za labotale.
Zosefera zapachipinda zoyera zimagawidwa molingana ndi magwiridwe antchito (kuchita bwino, kukana, kugwirizira fumbi), nthawi zambiri zimagawidwa kukhala zosefera zowoneka bwino, zosefera zapakatikati, zosefera zapamwamba komanso zapakatikati, komanso zosefera zazing'ono. Zosefera mpweya, Zosefera zapamwamba kwambiri (HEPA) ndi zosefera zapamwamba kwambiri (ULPA) mitundu isanu ndi umodzi ya zosefera.
Makina osefa makamaka amaphatikizapo kutsekereza (kuwunika), kugundana kwa inertial, kufalikira kwa Brownian ndi magetsi osasunthika.
① Kutsekereza: kuwunika.Tinthu tokulirapo kuposa maunawa timalowetsedwa ndikusefedwa, ndipo tinthu ting'onoting'ono kuposa mauna timadumphira.Nthawi zambiri, zimakhudza kwambiri tinthu tating'onoting'ono, ndipo magwiridwe ake ndi otsika kwambiri, omwe ndi njira yosefera ya zosefera zowoneka bwino.
② Kugunda kwa inertial: tinthu tating'onoting'ono, makamaka tinthu tating'onoting'ono, timayenda ndi mpweya ndikuyenda mwachisawawa.Chifukwa cha inertia ya tinthu tating'onoting'ono kapena mphamvu inayake ya m'munda, amapatuka kuchokera komwe amapitako, ndipo samasuntha ndi mpweya, koma amalimbana ndi zopinga, kumamatira kwa iwo, ndikusefedwa.Kukula kwa tinthu tating'onoting'ono, kumapangitsa kuti inertia ikhale yowonjezereka komanso yowonjezereka.Nthawi zambiri ndi kusefera kwa zosefera zowoneka bwino komanso zapakati.
③ Kufalikira kwa Brownian: Tizigawo ting'onoting'ono ta mpweya timapanga kuyenda kosasinthika, kugundana ndi zopinga, kumamatira ndi mbedza, ndipo kumasefedwa.Tinthu tating'onoting'ono, mphamvu ya Brownian imayenda bwino, mipata yambiri ya kugundana ndi zopinga, ndipamwamba kwambiri.Izi zimatchedwanso diffusion mechanism.Uku ndiye kusefa kwa zosefera zazing'ono, zogwira mtima kwambiri komanso zosefera kwambiri.Ndipo kuyandikira kwa ulusi wa m'mimba mwake ndi kukula kwa tinthu, zotsatira zake zimakhala bwino.
