Argon - mea he kūikawā hehee ai o ka papa'āweʻaweʻa kemika'ōnaehana

Mākou a pau i ike i argon ua hoʻohana 'ia no ka kuʻihao dissimilar ke hooheheeia, akā,ʻaʻole mea i manao ai, i mea no ka Nine Inch hehee ai. Akā, kona mōʻaukala mea waiwai i loko o hanana. Tellingly, argon - mea he loaʻa kekahi manawa o ka papa'āweʻaweʻa kemika papaʻaina, aʻaʻohe analogues. Ke nä känaka 'epekema iho kahaha aku la i ka manawa ana i kona hiki loa kiʻi' aneʻi.

Ka lewa he ma kahi o 0,9% o keia kinoea. Like naikokene, ia mea'ākilikai a me ka odorless. E mālama aku ai i ke ola, ka mea, aole i pono, akā, e mea wale irreplaceable i loko o kekahi mau mea o kanaka haʻawina.

A wahi moʻolelo

Ua Ua mua ike he Pelekāne a me ka physicist ma ka nooaai? G. Cavendish, ka poe i kaulana i ka alo i loko o ka lewa o ka mea hou, i mea hoʻopale i Nine Inch hoouka. Eia naʻe, i loaʻa mai Cavendish i ke ano o ka mea hou kinoea. A uuku oi ma mua o ka haneri makahiki ma hope, ka mea, ua ike a me kekahi nä känaka 'epekema - John William Strutt. He hiki i ka hopena i naikokene mai ka lewa he mea kekahi admixture o ke kinoea o ka hihipeʻa o ka molekumu o, akā, he mea argon ai kekahi mea'ē aʻe,ʻo ia hiki ole i ike.

A hiki i ke kinoea, aole ia i pane koke me nā mea hiki ke hooheheeia, chlorine, nāʻakika, alkalis. Ia mea, mai ka Nine Inch wahi o Hawaii i lawe i ka inert ano. Akā, i kekahi mea hou i ka loaʻa - ka hou kinoea lātoma kikowaena hoʻokahi wale'Ātoma. A i ia manawa, he like me ke kinoea haku mele 'ana ua nō IKE OLE IA.

Palapala i ka lehulehu e pili ana i ka mea hou kinoea i kūpono i ka kŰia i na mea he nuiʻepekema mai a puni ka honua - e like me ka mea i hiki ke kala i ka hou kinoea i loko o ka lewa no ka mea he nui ka noiʻi a me ka ho okolohua?! Akā, i ka loaʻa manaoio ole a pauʻepekema, a me Mendeleev. E like me ka'ātoma nuipa o ka hou kinoea (39.9), ka mea, e lohe ÿana ma waena o potasiuma (39.1) a me ka kalipuna (40.1), akā, i ke kulana i nei hana.

E like me ua oleloia, argon - he kinoea me ka waiwai, a me ka Makäkiu moʻolelo. No kekahi manawa ka mea, ua poina, akā, hou kinoea kauoha aku ike ma hope o ka loaʻa o ka helium. Ua Ua hooholoia e haalele i ka hookaawale Aʻohe oihana no ka mea, aia i loko o waena o nā halogens a me ka mekala 'åkilikai ke hooheheeia.

waiwai

I waena o nā inert kinoea i i hoʻolako 'ia e ka ikaika pae, argon ua noʻonoʻo i ka easiest. Kona nuipa aku i ke kaumaha o ka lewa i loko o 1,38 manawa. Ke kinowai kinoea i loaa mai i ka wela o ka -185,9 ° C, a ma -189,4 ° C a me ka maʻamau puʻe hoopaakiki hoi.

O ka helium a me ka Neon, argon, wehewehe aku i loko i ka mea i hiki ke hoike mai i loko o ka wai - i 20 degere ma ka nui o 3.3 ml no hoʻokahi haneri nā huna o ka wai. Akā, ma ka helu o ke aloha pāʻoihana kinoea hoike mai maikaʻi. Waiwai o ka uilaʻikena ke kumu no ia e glow, no laila, i ka mea i lohe nui ia i loko o ka ho'ā nā lako a pan.

Biologists ike kekahi mea pono keia mau waiwai, i mea argon. Kēiaʻano o ka papa kahi a ka mea kanu māhuahua, a ua hoao ia e ho okolohua. No laila, oiai i loko o ka lewa, kanu i ka anoano o ka laiki, kulina, kaʻukama a me ka rai i kā lākou mau kupu ma ka hopena. Ma kekahi 'ia ma 98% mea argon a me ka 2% - no o oxygen, maikai omaka ae ia nō hoʻi na hua e like me carrots, lettuce, a me onions.

He aha ka oi loa ano o ka maʻiʻo o keia kinoea i loko o ka honua ka pńpa mea nui nui ma mua o ka mea 'ē aʻe hehee wale i loko o kona pae. Kona He kokekau wale maʻiʻo - 0,04 g. No tonne. He 14 manawa i ka nui o ka helium a me 57 mau manawa - Neon. Me ka pili ana i ka ke ao holoʻokoʻa a puni mākou, ia ma laila i oi, loa i loko o keʻano like hoku a me nebulae. E like me ka hiki i kekahi koho, ma ka argon makahiki aouli oi aku ma mua o chlorine, phosphorus, kalipuna a me ka potasiuma, i mea hoakaka i loko o ke ao nei.

Kaniak kinoea

Ke argon nā paukūʻolokaʻa ma a mākou pinepine halawai, o ka inexhaustible kumu. No hoi, ma kekahi hihia, ua hoi aku la i ka lewa aie i ka mea i ka wā me ka hoʻohana 'ole hoʻololi i loko o ke kino ai' ole Nine Inch hua'ōlelo. Ke koe paha e hihia o ka hokii, a dala uuku o ka argon isotopes i loko o ka? Iecaianoaaiiie o hou isotopes a me nā kumumea i loko o ka papa o nukelea reactions.

I hana, ke kinoea hua mai ma ke kaawale ana i loko o o oxygen, a naikokene mea lewa. Ke kūpono kinoea Ua hānauʻia me he he hopena ia. No keia mea kūikawā hanalima lako a me nā papalua rectification kolamu kiʻekiʻe a me ka haahaa puʻe a me ka palapala condenser-evaporator. Eia hou kekahi, wao ammonia? Iecaianoaaiiie hiki ke hoʻohana i ka paka argon.

poepoe o ka palapala noi

Laulā o ka argon loaʻa paha kekahi mau wahi:

• ai ka hana;
• metallurgy;
• noiʻi a me ka ho okolohua;
• kuʻihao;
• uila no;
• ke kaʻa hana.

He He'ākilikai kinoea i loko o ka uila lapochek i ka lohi o ka omoāea o tungsten'ōwili hao oloko. No ka mea, o keia waiwai ua hoʻomano hoʻohana 'ia me ka nānā ma kēia kinoea kuʻihao mīkini. Argon mau hiʻohiʻona nō ike loea e pili ana i māhele o ka Aluminum a me ka duralumin.

He ākea loaa kinoea, e hana i kekahi aiiay a me ka inert lewa. He i hookuu pono no ka wela lapaʻau o ke hooheheeia, a i hoopuni ke'okesaside. ʻO nā pōaka ulu maikaʻi i loko o ka argon lewa, e loaa i kekahi mea uholo uila hehee ai aʻoi loa-maemae mea.

Pono a me keakea o ka palapala noi o argon i loko o ka kuʻihao

E pili ana i ka kuʻihao argon haawi i kekahi mau pono. Mua o nā mea a pau, i ka mea hiki ke hooheheeia wahi i kuʻihao mea ole pela wela. He hookaaokoa ae mai o deformation. No nā pono nā:

• ike loea hoomalu ana o ka weld;
• uku o ka argon kuʻihao mea nui kiekie ae;
• kaʻina mea oluolu no ka mana;
• kuʻihao hiki e mechanized paha maopopo huli 'akomi pololei ia;
• hiki i ka hui pu iho māhele o kekahi mea hiki ke hooheheeia.

I ka Ia manawa, argon kuʻihao, a komo i ka helu o ke keakea:

• kuʻihao ia lŘlŘ ultraviolet pāhawewe;
• no ka kiʻekiʻeʻikena piʻo e pono like ai ka huʻihuʻiʻana;
• apau i hana i loko o ka wehe ea a kikoo.

Aka hoi, i ke alo o laila, na pono ia mea paakiki e underestimate i ka waiwai o ka argon kuʻihao.

precautionary ana

I ka hoʻohana argon e e makaala lakou. Aka, kinoea meaʻawahia, akā, hiki i asphyxiation ma ke kūapoʻana i oxygen a liquefying ia. He Nolaila loa nui i ka pāʻana i ka nui o ka O ₂ ma ka lewa (ma ka liʻiliʻi loa 19%) ma ka mea o kūikawā manaʻo, e manual paha akomi.

Ka hana ana me ka wai a kinoea pono lōʻihi mālama nui like argon haʻahaʻa wela hiki i hanahana loa frostbite o ka ili a me ka poho i ka maka o ka iwi. He mea pono e hoʻohana goggles a me ka nohona ma. Mea pono e lawe mai hana ma lalo o ka argon lewa, pono e komo ea paha 'ole' ē aʻe hō'īpale ka oxygen na manao ona.
