I ka pa apŘ o ke tungsten. Ka waiwai a me ka noi o ka tungsten

He aha ka i ka pa apŘ o ke tungsten? He aha ka ke kumu o kona palapala noi? E imi mākou pane i kēia mau nīnau a pau.

Ke kahua ma ka SS

He He Nine Inch hehee ai i loko o ka ono o ka pūʻulu o ka papa'āweʻaweʻa kemika nenoaiu. Kona pūkaʻina helu 74, o ka nui o na hoahanau'ātoma nui o 183,85. Ke kūikawā waiwai o ka tungsten e hooponoponoia ia mea, ma kona kiʻekiʻe heheʻe wahi. He ua manaoia kekahi o ka loa refractory ke hooheheeia. Ma ka tungsten maoli he elima ka pilina paʻa isotopes, a i like nuipa a nui mai ka 180 a hiki i 186.

Opening hehee ai

Kēia Nine Inch hehee ai i loaa i loko o ka hopena o 18th kenekulia. Scheele K. pomaikai i kaʻawale ia, mai ka mea pōhaku, kahi o ka mea hiki ke hooheheeia ua kakauiaʻi maluna me ka'okesaside. Tungsten lōʻihi manawa i kokoke ole hanalima noi, ka mea, i ole, ua koi. Wale nō i loko o ka hapalua like-19th kenekulia, hoomaka ae la ka mea hiki ke hooheheeia e ke hoʻohana 'me ka mea hoʻonui i loko o ka hana o ka kiʻekiʻe ikaika kila.

Contents ma ke ano maoli

Ma ka pńpaʻeleu lālā mea i loko o ka nīnūnē nui. Ua noa palapala uaʻaʻole i loaʻa, ka mea, ua aia i loko o ka palapala o nā minelala hao wale. Ma hanalima me ka unahiʻole e hoʻohana kona oxides.

physical waiwai

19300 - he tungsten nuʻa Kg / m3 ma maʻamau ana. Ka mea hiki ke hooheheeia 'ano apau loa i ke kino-e pili ana cubic puka olu oia i concentric. He He He anakahi maikai o ka wela 'auhau. High wela kaʻi lau waiwai tungsten wehewehe kona refractoriness. Ka mahele heheʻe i ka mehana o 3380 kekelē Kelekia. Ke ÿano waiwai o ololi kona pretreatment. Ua haawiia tungsten nuʻa me 19 3 g. / Cm3 i 20, e hiki ke lawe i ka moku'āina o ka mea hookahi aniani puluniu. Keia waiwai ua hoʻohana 'ia i loko o ka hana o ka uea mea. Ma na kumu o ka mehana o ka tungsten mai he uuku ductility.

tungsten Hiʻona

Lula 'nuʻa tungsten attaches i kēia mea hiki ke hooheheeia wahi waiwai. He mea nō i ka haahaa ana o ke omoāea, kiʻekiʻe baila aʻela i wahi. Ma hua'ōlelo o ka uila conductivity haʻahaʻa ma mua ia o ka tungsten keleawe ekolu mau manawa. He He pa apŘ nui o ka tungsten, e kali i ka laulā o kona hoʻohana. Eia hou, kona hoʻohana loli loa fragility ma haʻahaʻa mahana, instability e'okesaside ma ka lewa i oxygen ma haʻahaʻa mahana.

By mawaho ano tungsten Ua like ke kila. Ua ua hoʻohana 'ia no ka hana o ka oka a me ka mahuahua ikaika. tungsten aaioee ua hana i ka ke kiekie ana wela wale.

tungsten A hehi ihola au

'Aʻole wale i ka pa apŘ o ke tungsten, akā, me ka mea hoʻonui i hoʻohana ma ka metallurgy, e ike i ka hoailona o ka metala. No ka laʻana, IA kuhi i ka läÿau, o ka tungsten me ka Aluminum a me ka silikone. I ka mea kūpono papa kuni typical loiloi mua recrystallization, i ka ikaika ma hope annealing.

Ua komo ai pepa lolo e tungsten me ka mea hoʻonui i lanthanum'okesaside i maoli ka ea puka waiwai o ka mea hiki ke hooheheeia.

CF - he oka a pau o ka tungsten a me ka molybdenum. Oia haku mele 'ana hoonui ae i ka ikaika, ductility metala i hoopaa mai ai ma hope o annealing.

Kahua o ka tungsten ka hoʻohana 'ana

Ke kūlana waiwai o ka mea hiki ke hooheheeia predetermine kona palapala noi. Ma ka hanalima me ka unahiʻole, ka mea, ua hoʻohana 'ia i loko o ka palapala maemae, a me oka a pau.

Tungsten i loko o ka hale hoʻohanaʻano nui ma ka pou noi.

I ka ka mea, ua i ka? Iecaianoaaiiie o kiʻekiʻe mämä holo steels hoʻohana like me ka papa kuhikuhiE ke keʻena (alloying hehee ai). Ma awelika, me ka tungsten maʻiʻo mea mai ka eiwa a hiki i ka iwakalua pakeneka. Eia hou kekahi, oia ka hapa o ka mea paahana kila.

Oia o io steels i hoʻohana ai no ka hana o ka mīkini wili pōhaku kālai,? Eou, punches, make. No ka laʻana, kiʻekiʻe-ka māmā holo kila R6M5 ka hōʻike i ua oka a ke kila me ka cobalt a me ka molybdenum. Eia kekahi, tungsten ua iloko o loko o kaʻume mākenēki steels e māheleʻia i loko o volframokobaltovye a me ka tungsten? Ueo.

Tungsten ma maʻamau o ke ola kūpono kou i koi i loko o ke gula palapala. Tungsten carbide mea he huina lakou o ka mea hiki ke hooheheeia me ka kalapona. Ka hui Ua wehewehe aku ma kiʻekiʻe paakiki, refractoriness, e mae wale ia'ku like hoʻi. Ma ke kumu o ka tungsten carbide mea paahana i i hoʻomāhuahua ai paa oka a pau i loaʻa ma kahi o 90 pakeneka tungsten, a ma kahi o 10 pakeneka cobalt. Hard metala ana i kauwahi ho okumuʻeli, a okioki i na mea paahana.

ʻano likeʻole o nā steels ka nānā 'ana ma luna o tungsten

Lei-hoʻopale a me ka wela-hoʻopale oka a me ka nānā 'ana ma tungsten infusibility. I hana i huiʻia, he pono ole tungsten me ka cobalt a me ka chromium, i ka poe i kaheaia stellite. Lākou ma ka kuʻihao noi ma luna o ka Wear hapa o nā māhele o ka hanalima machines.

"Kaumaha" a me ka hui 'oka a - he läÿau, o ka tungsten me ka kala, a me ke keleawe. Ka mea, i manaoia lawa i nolaila, hoʻohana 'ia ka hoʻokō hui' mea no ka? Iecaianoaaiiie o ka hana mau māhele o ka hui '-nā uila aʻa lolo no ke kina ole kuʻihao, a me ka Ioi o ka huakai kaapuni nalu.

Ma ka palapala o ka uea, forged 'atikala, tungsten lipine hoʻohana i ka uila no, i loko o ka hana o ka uila kukui, e like me ka pono me ka' enehana X-Ray. He kēia mea hiki ke hooheheeia ua noʻonoʻo i ka pono mea e ho okumu spirals a me filament nā huakaʻi.

Tungsten ua mau laau la a me nā kaula i pono ai no ka hana o ka uila heaters no kiʻekiʻe ana wela umu. e hiki ke hana ma lalo o ka inert kinoea lewa o ka hydrogen, a ma vacuo Heaters ka nānā 'ana ma luna o tungsten.

Kekahi o ka mea nui loa nāʻoihana o ka pono o ka tungsten ua kuʻihao. Mau mea e ho okumu i nā uila aʻa lolo i mea hoʻohana no ka piʻo kuʻihao. Ua kūpono nā uila aʻa lolo i manaoia nonconsumable.

Makaukau o refractory metala

Pehea ka nui o ka tungsten? Price no kg mea i loko o ka laulā mai ka 900 a hiki i 1200 rubles. Ka mea, no a hiki i ka pae ana o ke nānā metala hehee wale. Nō hoʻi 'aneʻi ka ia ano like tungsten rubidium, molybdenum. Pohihihi keia mea hiki ke hooheheeia e nīnūnē ka unahiʻole, i no ka mea, o ko lakou mailuilu haalele lehulehu i loko o ka honua o ka pńpa. None o kēia mau mea hiki ke hooheheeia hiki ole ke loaa ma ka pololei ka ho'ēmiʻana o ka maka mea. E hoʻomaka me ka maka hoʻokō 'ia no kela Nine Inch. E noke i lawe mai, a hana hou aaioee o ke hooheheeia no ko lakou piha aaioee.

Ma ka aaioee ke kaula gula e loaa ana pohihihi tungsten i ekolu kahua o ka hoʻonaʻauao. Mua o ka mea e hoohehee ai decomposition ua lawe mai ma ka hookaawale ana i ka loaʻa hou metala ma ke kaupaonaʻana o ka maka mea, e like me kona lehulehu i loko o ka precipitate a me ka pāʻoihana. Hou ke loaʻa nā chemically maʻemaʻe i huiʻia, koho ua haliia mai la mawaho, a me ka, i ka hoʻomaʻemaʻe Nine Inch. Ke kolu o ke kahua me ua kaʻawale mai ka maloko metala mai ka'okesaside impurities.

E like me ka maka mea i loko o ka hana o ka tungsten hana wolframite. He mea e hoohehee ai kekahi mau ma kahi o elua pakeneka, he mea hiki ke hooheheeia. Mea i eliia, ua lawe mai ma ka flotation, umekaumaha, electromagnetic a pahaʻume mākenēki kaawale ana. Ma hope o enrichment tungsten kiaʻana i kāna ua hana, a iloko ona i kakauia ma kahi o 65 pakeneka tungsten'okesaside (6). Ma waho aʻeo i ka mea hiki ke hooheheeia, ua noʻonoʻo iloko impurities o ka luaipele, keleawe, phosphorous, arsenic, bismuth, antimony. Pehea ka nui o ka tungsten? Ke kumukuai no kilogram mea e pili ana i ke tausani rubles. E paka tungsten ka pauka, ka mea, ua pono i ka loaa ana o ke kalapona'okikene lua a me hydrogen.

ʻano nui hoʻohana hydrogenation hana, mai kalapona ua hou metala embrittlement mai i ka hopena maikaʻi ma luna o kona processability. Special ki ina hana like i hoʻohana ai no ka hana o ka tungsten ka pauka, a ae e kālailai i ka haku mele, ai ka nui a me ka haku mele 'ana o nā granules hana.

Olelo hoopomaikai hydrogenʻano nui i loko o ka palapala o nā lāʻau kī, a ingots i hoʻohana like preforms i loko o ka hana o ke kalaka nui-pau huahana e like me lipine, uea.

Ka mau Ke hoʻohana ki ina hana like o ka pili ana olelo hoopomaikai tungsten. Ka papa hana mua komo ai i ka hoʻohana 'ana o ka pauka metallurgy. E like me ka lua o ke kaʻina hana no Ke aeia'ku nei ia i ka hoʻohana 'ana o ka uila piʻo umu ahi ke komo pū i ka hana o consumable nā uila aʻa lolo.

Ka loa e like me ka ano o nā huahana i lawe mai tungsten mea hiki ke hooheheeia, a mai ka kūikawā manaʻo nui, e tungsten mau laau la. I hoomakaukau e forging o forging o nā lāʻau kī, ma luna o ke kupaianaha mīkini. Pau huahana hoʻohana 'ia i loko o kekahi mau nāʻoihana o kēia hana. No ka laʻana, no ka mea, o ko lākou non-consumable'ūholo uila kuʻihao ua loaa. Eia hou, e hoʻohana i ka tungsten mau laau la, i ka wa e pili ana heaters. Ka mea, i loko o ke koi ma ke kinoea hookuuia manaʻo, ka pila pu u kukui.
