Nā kānana Molekule: E aʻo e pili ana i kā lākou mau noi a me nā hoʻohana

 

hoolauna

 Nā kānana molekula, ʻike ʻia hoʻi ʻo zeolite synthetic, he mau mea porous e koho koho i nā molekala ma muli o ko lākou nui a me ka polarity. ʻAe kēia waiwai kūʻokoʻakānana molekulae ʻimi i ka nui o nā noi ma nā ʻoihana like ʻole. Ma kēia ʻatikala, e ʻimi hohonu mākou i ka nīnau "He aha nā kānana molekala i hoʻohana ʻia no?" a e ʻimi ana i kekahi mau noi maʻamau i nā kikoʻī.

 

Nā noi ʻenehana

ʻO kekahi o nā noi nui loa o nā kānana molekala ma ka ʻoihana kinoea a me ka ʻaila. He kuleana koʻikoʻi nā kānana molekula i ka wehe ʻana i ka makū a me nā haumia mai ke kinoea maoli, i kūpono ia no ka lawe ʻana a me ka hoʻohana ʻana. Pēlā nō, hoʻohana ʻia nā kānana molekala i nā kaʻina dehydration ethanol a me ka hoʻomaʻemaʻe ʻana i nā hydrocarbons, e hiki ai ke hana i nā wahie kiʻekiʻe a me nā kemika.

Eia kekahi, ua hoʻohana nui ʻia nā kānana molecular i nā kaʻina hoʻokaʻawale ea, me ka hana ʻana o ka nitrogen, oxygen a me nā kinoea ʻoihana ʻē aʻe. ʻO ka hiki ʻana o ka adsorption o nā kānana molecular e kōkua i ka hoʻokaʻawale ʻana i ka oxygen mai ka lewa, e hana ana i ka oxygen maʻemaʻe kiʻekiʻe e kūpono ana i nā pono o nā ʻoihana he nui e pili ana i ka mālama olakino, welding a me ka ʻoki metala.

I ka ʻoihana petrochemical,kānana molekulahana ma ke ʻano he catalysts a i ʻole adsorbents i ka wā o ka hoʻololi ʻana a me ka hoʻomaʻemaʻe ʻana. Kōkua lākou i ka wehe ʻana i nā mea haumia e like me ka sulfur a me carbon dioxide a hoʻonui i ka hana o nā catalysts, e hoʻonui ana i ka hana ʻana o nā kemika a me nā wahie.

Hoʻohana kaiapuni

ʻO ka hiki i nā kānana molekole ke hoʻopili i nā molekole wai mai nā wai a me nā kinoea e waiwai ai lākou i nā ʻano hana kaiapuni. ʻo kahi laʻana,kānana molekulahoʻohana ʻia i loko o ka refrigeration a me nā ʻōnaehana ea e wehe i ka wai, pēlā e pale ai i ka corrosion a me ka hau.

 

Eia kekahi, hoʻohana nui ʻia nā kānana molekala e like me nā desiccants i nā mea hoʻopihapiha e mālama ai i nā huahana e like me nā lāʻau lapaʻau a me nā mea uila. ʻO nā waiwai hygroscopic o nā kānana molekula e hōʻoia i ka mālama maikaʻi ʻana a hoʻonui i ke ola o kēia mau waiwai koʻikoʻi.

 

nā noi lāʻau

Ma ke kahua lapaʻau,kānana molekulahe hana koʻikoʻi i ka hana ʻana i ka oxygen olakino a me ka wehe ʻana i ke kalapona mai ka ea exhaled i ka wā anesthesia. Kōkua lākou i ka mālama ʻana i nā kinoea lāʻau lapaʻau me ka palekana a me ka maikaʻi, hoʻomaikaʻi i ka mālama maʻi.

 

i ka hopena

I ka pōkole, loaʻa i nā kānana molecular ka nui o nā noi a he mau mea koʻikoʻi i loko o ke kinoea maoli, ka ʻaila, ka petrochemical, ka palekana o ke kaiapuni, ka lāʻau lapaʻau a me nā ʻoihana ʻē aʻe. ʻO kā lākou hiki ke koho i nā molekala e pili ana i ka nui a me ka polarity e pono ai lākou no nā kaʻina hana mai ka dehydration a me ka hoʻomaʻemaʻe ʻana i ka hoʻokaʻawale ʻana i ka ea a me nā hopena catalytic. Ke hoʻomau nei ka noi ʻana no ka hoʻomaʻemaʻe, ʻoi aku ka maikaʻi o nā ʻenehana, ʻoi aku ka nui o nā kānana molecular i mea nui i nā noi ʻoihana a me nā kaiapuni.
