E noʻonoʻo i ka loaʻa ʻana o ke apo ʻaʻole e wī a e noho nani ana e like me ka lā āu i kūʻai mai ai.
ʻO ka tungsten maʻemaʻe kahi mea hao kila kila kila paʻa i hana i kahi hapa liʻiliʻi o ka honua honua (ma kahi o 1/20 auneke ma kēlā me kēia tona o ka pōhaku). ʻAʻole kū ʻo Tungsten ma ke ʻano he metala maʻemaʻe i ke kūlohelohe. Hoʻohui mau ʻia ma ke ʻano he hui pū me nā mea ʻē aʻe. ʻO ke kūpaʻa kūpikipiki kiʻekiʻe a paʻa ka mea kūpono loa ia no nā mea kāhiko. Hoʻohui ʻia ka hao me kahi mea hoʻopaʻa nickel kiʻekiʻe e hana i kahi ʻāpana paʻakikī, ikaika a ʻumeʻume.
Hiki i ka Platinum, palladium a i ʻole nā apo gula ke kaha maʻalahi, ʻūlū a pelu. ʻAʻole kūlou nā apo ʻo Tungsten a e nānā ke nānā aku i ka nani e like me ka lā āu i kūʻai mua ai. ʻO Tungsten kahi mea hao paʻa ʻoi aku ka paʻakikī. Hiki iā ʻoe ke ʻike i ka maikaʻi ma ke kaupaona kaumaha ma ka tungsten. Ke hoʻohui ʻoe i ke kaupaona paʻa a me ka polish mau o ka tungsten i hoʻokahi apo, hana ʻoe i kahi hōʻailona kūpono o kou aloha a me kou kūpaʻa.
Nā mea e pili ana iā Tungsten:
Hōʻailona Kemika: W
Helu ʻĀtoma: 74
Kuhi Melting: 10,220 kekelē Fahrenheit (5,660 kekelē Kelekia)
Ka nui: 11.1 auneke i kēlā me kēia iniha cubic (19.25 g / cm)
Isotopes: ʻElima mau Isotopes Kūlohelohe (ma kahi o iwakāluakūmākahi mau isotopes hana lima)
Inoa Kinohi: ʻO ka huaʻōlelo "tungsten" mai nā huaʻōlelo Suedena tung a sten, ʻo ia hoʻi "pōhaku kaumaha"
Ke Kaʻina Hana.
Hoʻokomo ʻia ʻo Tungsten pauma i loko o nā apo hao paʻa me ka hoʻohana ʻana i kahi hana i kapa ʻia he sinter. Hoʻopili paʻa kahi kaomi i ka pauka i loko o kahi hakahaka o ke apo. Hoʻonā ʻia ke apo i loko o ka lua ahi ma 2,200 kekelē Fahrenheit (1,200 kekelē Celsius). Mākaukau nā kāʻei male tungsten no ka hana hewa. Hoʻohana ʻia kahi hana hewa hewa pololei. Pili kēia i ka hele pololei ʻana o kahi au uila ma o kēlā me kēia apo. Ke piʻi nei ka manawa, hoʻomehana ke apo i 5,600 kekelē Fahrenheit (3,100 kekelē Celsius), e emi ana i loko o ke apo paʻa i ka paʻa ʻana o ka pauka.
Hoʻonohonoho ʻia ke apo a hoʻonani ʻia me ka hoʻohana ʻana i nā mea hana daimana. No nā apo me ke kālā, gula, palladium, platinum a mokume gane inlays, nā mea hana daimana e ʻeli i kahi kahawai i waenakonu o ke apo. Hoʻokomo ʻia ka mea hao maikaʻi i loko o ke apo ma lalo o ke kaomi a hoʻomaikaʻi hou ʻia.
ʻO Tungsten Rings Vs ʻO Tungsten Carbide Rings?
Aia kekahi ʻokoʻa nui ma waena o ke apo tungsten a me kahi apo ʻo karbst tungsten. ʻO Tungsten i kona ʻano maka kahi mea kila hina e palupalu a paʻakikī e hana pū. Kahi ʻia ka mea hao oho e ka wili ʻana i loko o ka pauka a hoʻohui ʻia me nā mea kalapona a me nā mea ʻē aʻe. Hoʻopili pū ʻia kēia mau mea āpau e hana i ka tungsten carbide. Seldom e ʻike ʻoe i kahi apo tungsten maʻemaʻe, akā aia nō lākou. ʻOi aku ka ikaika o ke apo ʻo Tungsten carbide a ʻoi aku ka pale ma mua o nā apo ʻē aʻe.
ʻO kekahi o nā hiʻohiʻona nui loa o kahi apo ʻo ka tungsten carbide ʻo ia ke kūpale kūpilikiʻi. Aia wale kekahi mau mea ma kēia honua e hiki ke wili i kahi apo tungsten e like me ke daimana a i ʻole kekahi mea o ka paʻakikī like.
Hele mai kēlā me kēia o kā mākou mau kūpeʻe tungsten me kahi palapala hoʻokō ola mua ʻole ʻia. Inā kū kekahi mea i kāu apo, e hoʻomaopopo wale iā mākou ae mālama mākou ia.
Loaʻa i kāu mau apo tungsten nā cobalt?
ʻAʻole loa! Nui a hewahewa nā kūpeʻe karbona tungsten i ka mākeke e loaʻa ana i ka cobalt. ʻAʻohe o mākou cobalt i loko o kā mākou mau apo. ʻO Cobalt kahi kumu kūʻai maʻalahi o nā mea kūʻai aku ʻē aʻe e hoʻohana ai e hana i nā apo tungsten. Hana ka cobalt i loko o kā lākou mau apo me nā huna kūlohelohe o ke kino a ʻino ia, e hoʻohuli i kāu apo i kahi hina hina a waiho i kahi kala a ʻeleʻele i kou manamana lima. Hiki iā ʻoe ke hōʻalo i kēia ma ke kūʻai ʻana i hoʻokahi o kā mākou apo ʻoihana tungsten carbide i loaʻa ʻole ka cobalt.
