He aha ka metala Barium?

ʻO ka Barium kahi mea metala lepo alkaline, ʻo ke ono o ka manawa o ka hui IIA ma ka papaʻaina manawa, a me ka mea ikaika i ka metala honua alkaline.

1、 Hoʻolaha maʻiʻo

ʻO ka Barium, e like me nā metala honua alkaline ʻē aʻe, ua puʻunaue ʻia ma nā wahi āpau o ka honua: ʻo ka mea i loko o ka ʻōpala o luna he 0.026%, aʻo ka awelika waiwai o ka ʻōpala he 0.022%. Aia ka Barium ma ke ʻano o ka barite, sulfate a i ʻole carbonate.

ʻO nā minerala nui o ka barium ma ke ʻano he barite (BaSO4) a me witherite (BaCO3). Hoʻolaha nui ʻia nā waihona Barite, me nā waihona nui ma Hunan, Guangxi, Shandong a me nā wahi ʻē aʻe ma Kina.

2、 kahua noi

1. Hoʻohana ʻoihana

Hoʻohana ʻia ia no ka hana ʻana i nā paʻakai barium, nā alloys, nā mea ahi, nā reactors nuklea, a me nā mea ʻē aʻe.

Hoʻohana nui ʻia ia i nā mea hoʻohui, e like me ke alakaʻi, calcium, magnesium, sodium, lithium, aluminika a me ka nickel.

Metala Bariumhiki ke hoʻohana ʻia ma ke ʻano he degassing agent no ka wehe ʻana i nā ʻano kinoea i loko o nā ʻōpala a me nā paipu kiʻi, a me ka mea hoʻopau degassing no ka hoʻomaʻemaʻe ʻana i nā metala.

Hiki ke hoʻohana ʻia ka Barium nitrate i hui pū ʻia me ka potassium chlorate, ka pauka magnesium a me ka rosin e hana i nā pōkā hōʻailona a me nā mea ahi.

Hoʻohana pinepine ʻia nā pūhui barium hiki ke hoʻoheheʻe ʻia e like me nā pesticides, e like me ka barium chloride, e hoʻomalu i nā ʻano mea kanu.

Hiki ke hoʻohana ʻia no ka hoʻomaʻemaʻe ʻana i ka brine a me ka wai paila no ka hana electrolytic caustic soda.

Hoʻohana ʻia ia e hoʻomākaukau i nā pigments. Hoʻohana ʻia nā ʻoihana lole a me ka ʻili e like me ka mordant a me ka rayon matting agent.

2. Hoʻohana lāʻau

ʻO ka Barium sulfate kahi lāʻau kōkua no ka hoʻokolokolo X-ray. He pauka keʻokeʻo me ka ʻala ʻole a me ka ʻala, hiki ke hāʻawi i ka ʻokoʻa maikaʻi i ke kino i ka wā o ka hoʻokolokolo X-ray. ʻAʻole komo ʻia ka lāʻau barium sulfate i ka ʻōpū o ka ʻōpū a ʻaʻohe hopena maʻi. ʻAʻole i loko o nā pūhui barium hiki ke hoʻoheheʻe ʻia e like me ka barium chloride, ka barium sulfide a me ka barium carbonate. Hoʻohana nui ʻia no ka radiograph gastrointestinal a i kekahi manawa no nā kumu ʻē aʻe.

3 、Kaʻina hoʻomākaukau

I ka ʻoihana, ua māhele ʻia ka hoʻomākaukau ʻana o ka metala barium i ʻelua mau ʻanuʻu: ka hoʻomākaukau ʻana i ka barium oxide a me ka hoʻohaʻahaʻa thermal metala (aluminothermic reduction).

Ma 1000 ~ 1200 ℃, hiki i kēia mau hopena ʻelua ke hana i kahi liʻiliʻi o ka barium. No laila, pono e hoʻohana ʻia ka ʻumeke e hoʻoneʻe mau i ka mahu barium mai ka wahi pane i ka condensation zone i hiki ai i ka pane ke hoʻomau i ka ʻākau. ʻO ke koena ma hope o ka hopena he mea ʻawaʻawa a hiki ke hoʻolei wale ʻia ma hope o ka mālama ʻana.

4 、Nā hana palekana

1. Nā pōʻino olakino

ʻAʻole ʻo Barium kahi mea koʻikoʻi no ke kanaka, akā he mea ʻawaʻawa. ʻO ka ʻai ʻana i nā pūhui barium hiki ke hoʻoheheʻe ʻia ke kumu o ka make ʻana o ka barium. Ke manaʻo nei ʻo ka awelika kaumaha o ke kanaka makua he 70kg, ʻo ka nui o ka barium i loko o kona kino ma kahi o 16mg. Ma hope o ka lawe hewa ʻana i ka paʻakai barium, e hoʻoheheʻe ʻia e ka wai a me ka waika o ka ʻōpū, kahi i alakaʻi ai i nā mea make a me kekahi mau make.

Nā hōʻailona o ka ʻawaʻawa paʻakai barium: ʻike nui ʻia ka paʻakai barium e like me ka huhū o ka ʻōpū a me ka maʻi hypokalemia, e like me ka nausea, luaʻi, ʻeha o ka ʻōpū, ka ʻōpū, quadriplegia, ke komo ʻana o ka myocardial, ka ʻōpū hanu, a pēlā aku. nā hōʻailona o ka ʻōpū e like me ka luaʻi ʻana, ka ʻeha o ka ʻōpū, ka ʻōpū, a me nā mea ʻē aʻe. ʻona i ka hihia o ka maʻi hui, a me ka gastroenteritis acute i ka hihia o ka maʻi hoʻokahi.

2. Kāohi pōʻino

Leakage lapaʻau pilikia

E hoʻokaʻawale i kahi i haumia a hoʻopaʻa i ke komo ʻana. E ʻoki i ke kumu hoʻā. Manaʻo ʻia e ʻaʻahu nā limahana mālama ulia pōpilikia i ka pale huna huna huna huna a me nā lole pale ahi. Mai hoʻopili pololei i ka leakage. Ka liʻiliʻi o ka leakage: pale i ka hoʻoulu ʻana i ka lepo a hōʻiliʻili iā ia i loko o kahi pahu maloʻo, maʻemaʻe a uhi ʻia me kahi ʻōpala maʻemaʻe. Hoʻololi hana hou. Ka nui o ka leakage: uhi ʻia me ka lole plastik a me ke kāwele e hōʻemi i ka lele. E hoʻohana i nā mea hana ʻole e hoʻololi a hana hou.

3. Nā hana pale

Ka pale ʻana i ka ʻōnaehana hanu: ʻO ka maʻamau, ʻaʻohe mea e pono ai kahi pale kūikawā, akā ʻōlelo ʻia e hoʻohana i kahi huna lepo kānana ponoʻī ma lalo o nā kūlana kūikawā.

Pale maka: e hoʻohana i nā maka aniani palekana.

Palekana kino: komo i ka lole pale kemika.

Pale lima: e hoʻohana i nā mīkina lima.

ʻO nā mea ʻē aʻe: ʻAʻole pāpā ʻia ka puhi ʻana ma ke kahua hana. E nānā pono i ka hoʻomaʻemaʻe pilikino.

5、 Ka waiho ʻana a me ka lawe ʻana

E kūʻai i loko o kahi hale kūʻai anuanu a me ka makani. E mālama i nā kumu ahi a me ka wela. Mālama ʻia ka haʻahaʻa haʻahaʻa ma lalo o 75%. E hoʻopaʻa ʻia ka pūʻolo a ʻaʻole e pili me ka ea. Pono e hoʻokaʻawale ʻia mai nā oxidants, acids, alkalis, etc., a ʻaʻole pono e hui ʻia. Pono e hoʻohana ʻia nā kukui pahū a me nā ʻoihana ea. ʻAʻole ʻae ʻia ka hoʻohana ʻana i nā mea hana mechanical a me nā mea hana maʻalahi e hana i nā huna huna. E hoʻolako ʻia ka wahi mālama me nā mea kūpono e loaʻa ai ka leakage.
