Sefepi sa moea
1. Lilaboratori tse sebelisoang haholo-holo bakeng sa microbiology, biomedicine, biochemistry, liteko tsa liphoofolo, gene recombination, le lihlahisoa tsa baeloji ka kakaretso li bitsoa laboratories tse hloekileng-biosafety laboratories.
2. Laboratori ea ts'ireletso ea likokoana-hloko e entsoe ka laboratori e ka sehloohong e sebetsang, lilaboratori tse ling le likamore tse thusang.
3. Laeborari ea biosafety e tlameha ho netefatsa polokeho ea motho, polokeho ea tikoloho, polokeho ea litšila le sampole polokeho, 'me e tsebe ho sebetsa ka polokeho nako e telele, ha e ntse e fana ka tikoloho e ntle le e ntle ea ho sebetsa bakeng sa basebetsi ba laboratori.
Lisefe tsa moea tse hloekileng li arotsoe ho latela ts'ebetso ea sefa (ho sebetsa hantle, ho hanyetsa, matla a ho ts'oara lerōle), hangata li arotsoe ka li-filters tse sebetsang hantle tsa moea, li-sefe tsa moea tse sebetsang hantle, tse sebetsang hantle haholo le tse mahareng le tse sebetsang hantle haholo. Lisebelisoa tsa moea, Sefefo sa moea se sebetsang hantle haholo (HEPA) le mefuta e tšeletseng ea lihloela tse phahameng haholo (ULPA).
Mochini oa ho sefa o kenyelletsa haholo-holo ho thiba (ts'ebetso), ho thulana ho sa feleng, ho hasana ha Brownian le motlakase o sa fetoheng.
① Thibelo: tlhahlobo.Likarolo tse kholo ho feta letlooeng lia kenngoa ebe lia tlhotloa, 'me likaroloana tse nyane ho feta letlooeng lia lutla.Ka kakaretso, e na le phello ho likaroloana tse kholo, 'me katleho e tlaase haholo, e leng mokhoa oa ho hloekisa oa li-filters tse sebetsang hantle.
② Ho thulana ho sa bonahaleng: likaroloana, haholo-holo likaroloana tse kholoanyane, li phalla ka phallo ea moea 'me li tsamaea ka tšohanyetso.Ka lebaka la inertia ea likaroloana kapa matla a itseng a tšimo, a kheloha tsela ea ho phalla ha moea, 'me ha a tsamaee le moea, empa a thulana le litšitiso, a li khomarele,' me a sefshoe.Ha karoloana e kholoanyane, ho na le inertia e kholoanyane le e phahameng ea katleho.Ka kakaretso ke mokhoa oa ho sefa oa lihloela tse mahoashe le tse mahareng tse sebetsang hantle.
③ Brownian Diffusion: Likaroloana tse nyane moeeng li etsa motsamao o sa tloaelehang oa Brownian, li thulana le litšitiso, li ts'oareloa ke lihakisi, 'me lia tlhotloa.Ha karoloana e nyane, motsamao oa Brownian o matla haholoanyane, menyetla e mengata ea ho thulana le litšitiso, 'me e phahamisa katleho.Sena se boetse se bitsoa "diffusion mechanism".Ona ke mokhoa oa ho sefa oa li-filters tse tlase, tse sebetsang hantle haholo le tse sebetsang hantle haholo.'Me ha bophara ba fiber bo le haufi le bophara ba likaroloana, phello e ba betere.
