Nā hiʻohiʻona ʻenehana o KN95|KENJOY

I kēia manawa i ko mākou ola i kēlā me kēia lā, pono mākou e ʻaʻahu i ka mask ma nā wahi a mākou e hele ai, akā ʻaʻole paha mākou i ʻike nuiKN95 mau maka.I kēia lā,nā mea hoʻolako maka e hoʻolauna iā mākou i ka ʻike kumu o nā masks KN95.

Puna maʻamau

ʻO KN95 kahi mask maʻamau Kina, ʻo ia kahi ʻano mask me ka particulate matter filtering efficiency i ko mākou ʻāina.ʻO nā masks KN95 a me nā masks N95 he like maoli nō ia i nā ʻōlelo o ka pono kānana kānana.

ʻO KN95 kahi mask maʻamau Kina, e hele mai ana mai ke kūlana aupuni Kina GB 2626-2019 "Respiratory Protective equipment self-priming filter Anti-particulate respirator".ʻO kēia maʻamau he maʻamau maʻamau ma Kina, i waiho ʻia e ka State Administration of Work Safety a ma lalo o ka mana o ka National Technical Committee for the Standardization of individual Protective equipment (SAC/TC 112).

pae ʻenehana

Mai ka manaʻo o ke ʻano o ka noi, pili kēia maʻamau i ka hoʻomaʻamaʻa pilikino maʻamau a me ka hoʻomaʻemaʻe ʻana i nā lako pale hanu e pale ai i nā ʻano ʻāpana like ʻole, e like me nā masks, nā wahi kūikawā ʻē aʻe (e like me ka anoxic environment, underwater operation, etc. ) ʻaʻole pili.

Mai ka wehewehe ʻana i nā mea ʻāpana, wehewehe kēia maʻamau i nā ʻano like ʻole o nā mea ʻala, e like me ka lepo, ka uahi, ka noe a me nā microorganisms, akā ʻaʻole ia e wehewehe i ka nui o nā mea particulate.

E like me ka pae kānana, hiki ke hoʻokaʻawale ʻia i ʻelua mau ʻāpana: kānana non-oily particulate KN a kānana oily a me non-oily particulate KP, a hoʻohana i kēia ma ke ʻano he hōʻailona, ​​e like me ka N a me R _ lima. P i kuhikuhi ʻia ma nā alakaʻi wehewehe o CFR 42-84-1995.

Nā mea pono e nānā

He mea pono ke hoʻomaopopo ʻia ʻo GB 2626-2006 "Respiratory Protective mea hoʻohuʻu iho kānana Anti-particulate respirator" kokoke e invalidated, e pani ana i kona mana hou o GB 2626-2019 "Respiratory Protection self-priming filter Anti-particulate respirator", i hāʻawi ʻia i ka hui holoʻokoʻa e ka State Administration of Market Supervision and Administration ma Dekemaba 31, 2019, a e hoʻokō ʻia ma Iulai 1, 2020. Hoʻopuka ʻia ka maʻamau hou a waiho ʻia e ka Emergency Management Department.

I kēia manawa, ua paʻi ʻia ka kikokikona o ka maʻamau hou a hoʻolako ʻia i ka lehulehu holoʻokoʻa me ka uku ʻole ma ke ʻano he maʻamau koi.Hoʻopiha ka maʻamau hou i ʻehiku mau huaʻōlelo e like me ka "aerodynamic particle size" a hoʻololi i kekahi mau koi ʻenehana a me nā ʻano hoʻāʻo, akā ʻaʻole ia e hoʻololi i ka hoʻokaʻawale ʻana, ka hōʻailona a me ka pono kānana i helu ʻia ma kēia pepa.

ʻO N95 kahi kūlana ʻAmelika

ʻO ka mask N95 kekahi o nā ʻano masks pale 9 i hōʻoia ʻia e NIOSH (National Institute of Occupational Safety and Health, National Institute for Occupational Safety and Health).ʻAʻole ʻo N95 he inoa huahana kikoʻī, ʻoiai ʻo ia ka mea e kū ai i ka maʻamau N95 a ʻo ka huahana i hala i ka loiloi NIOSH hiki ke kapa ʻia ʻo N95 mask, hiki ke kānana i nā ʻāpana me ke anawaena aerodynamic o 0.075 μm ± 0.020 μm me kahi ʻoi aku ka maikaʻi o ka kānana ma mua o 95%.

ʻO ka mea i luna nei ka hoʻolauna ʻenehana o KN95.Pono mākou e ʻike hou aku e pili ana i nā masks FFP2.E ʻoluʻolu e kelepona mai i kā mākouhale hana makano ka ʻōlelo aʻo.
