kānana ea
1. ʻO nā hale hana i hoʻohana nui ʻia no ka microbiology, biomedicine, biochemistry, hoʻokolohua holoholona, genetic recombination, a me nā huahana olaola i hui pū ʻia he hale hana maʻemaʻe-biosafety laboratories.
2. Aia ka hale hana biosafety me ka hale hana nui, nā hale hana ʻē aʻe a me nā lumi hana kōkua.
3. Pono ka hale hana biosafety e hōʻoiaʻiʻo i ka palekana pilikino, ka palekana o ke kaiapuni, ka palekana o ka ʻōpala a me ka palekana o ka laʻana, a hiki iā ia ke hana me ka palekana no ka manawa lōʻihi, ʻoiai e hāʻawi ana i kahi ʻano hana ʻoluʻolu a maikaʻi no nā limahana limahana.
Hoʻokaʻawale ʻia nā kānana ea lumi maʻemaʻe e like me ka hana kānana (ka maikaʻi, ke kūpaʻa, ka paʻa ʻana o ka lepo), ka mea maʻamau i māhele ʻia i nā kānana air coarse-efficiency, medium-efficiency air filters, high- and medium-efficiency air filters, and sub-high-efficiency nā kānana ea , High efficiency air filter (HEPA) a me ultra high efficiency air filter (ULPA) ʻeono ʻano kānana.
ʻO ka mīkini kānana ka nui o ka interception (screening), inertial collision, Brownian diffusion and static electricity.
① Hoʻopaʻa ʻia: nānā.Hoʻopili ʻia nā ʻāpana ʻoi aku ka nui ma mua o ka mesh a kānana ʻia, a ʻoi aku ka liʻiliʻi ma mua o ka mesh.ʻO ka maʻamau, he hopena ia i nā ʻāpana nui, a haʻahaʻa loa ka pono, ʻo ia ka mīkini kānana o nā kānana coarse-efficiency.
② Hoʻokuʻi inertial: nā ʻāpana, ʻoi aku ka nui o nā ʻāpana, e kahe me ka ea a neʻe wale.Ma muli o ka inertia o nā ʻāpana a i ʻole kekahi ikaika kahua, ua haʻalele lākou mai ka ʻaoʻao o ka ea, ʻaʻole e neʻe me ka ea, akā e hui pū me nā mea pale, pili iā lākou, a kānana ʻia.ʻO ka nui o ka ʻāpana, ʻoi aku ka nui o ka inertia a ʻoi aku ka kiʻekiʻe o ka pono.ʻO ka maʻamau, ʻo ia ka kānana kānana o nā kānana maikaʻi a me ke kala.
③ Brownian Diffusion: ʻO nā ʻāpana liʻiliʻi o ka ea e hana ʻole i ka neʻe ʻana o Brownian, e hui pū me nā mea pale, paʻa i nā makau, a kānana ʻia.ʻOi aku ka liʻiliʻi o ka ʻāpana, ʻoi aku ka ikaika o ka neʻe Brownian, ʻoi aku ka nui o ka manawa o ka hui ʻana me nā mea pale, a ʻoi aku ka kiʻekiʻe o ka pono.Kapa ʻia kēia ʻo ka diffusion mechanism.ʻO kēia ka mīkini kānana o nā kānana haʻahaʻa, kiʻekiʻe a me ka ultra-high efficiency.A ʻo ka pili kokoke ʻana i ke anawaena o ka fiber i ke anawaena particle, ʻoi aku ka maikaʻi o ka hopena.
