ʻO ka pā tungsten 99.95 maʻemaʻe wolfram pā
ʻO ka pā Tungsten me ka maʻemaʻe o 99.95% he mea kiʻekiʻe kiʻekiʻe a ua kapa pinepine ʻia ʻo tungsten plate. ʻO Tungsten, ka mea i kapa ʻia ʻo tungsten, he metala paʻa a paʻakikī me kahi helu hoʻoheheʻe kiʻekiʻe a me ke kūpaʻa corrosion maikaʻi loa. Hoʻohana maʻamau ia i nā ʻano hana ʻoihana like ʻole, me ka hana ʻana i nā pilina uila, nā mea wela a me ka pale radiation.

ʻO ka hoʻohana ʻana i nā papa tungsten he ākea loa, ʻo ia hoʻi akā ʻaʻole i kaupalena ʻia i ke kino nui o nā ʻoihana ʻoihana, nā paona yacht, nā mokulele ballast, kinetic energy armor piercing pōkā no nā mea kaua kaumaha, pale radiation, nā pōkā, nā pōkā / poʻo pōlele golf, Bob / mobile kelepona, vibrator uaki, etc
Hoʻopili ka hoʻohana ʻana i nā papa tungsten i nā kahua he nui, mai nā mea haʻuki a i nā mea kaua. Ma ke kahua o ka haʻuki, hoʻohana ʻia nā papa tungsten ma ke ʻano he kino nui o nā darts, a ʻo kā lākou kiʻekiʻe kiʻekiʻe a me nā waiwai kino maikaʻi e hoʻomaʻamaʻa pololei i nā darts. Ma nā kahua o nā moku a me nā mokulele, hoʻohana ʻia nā papa tungsten e like me nā mea kaupaona no nā yachts, ballasts no nā mokulele, a me nā mea kaupaona no nā kaʻa heihei F1, ʻo ia mau mea a pau e hōʻike ana i ke kuleana o nā pā tungsten i ka hoʻonui ʻana i ka paʻa a me ke kaulike. Eia kekahi, ua hoʻohana pū ʻia nā papa tungsten e hana i nā pūʻali koa kinetic ikehu no nā mea kaua koʻikoʻi, a ma ke ʻano he mea pale radiation no ka nuklea U-like mana lako, X-ray, a me nā mea lapaʻau ʻē aʻe, e hōʻike ana i kā lākou kuleana kūikawā i ka pale a me ka pale. ?
ʻO ka hoʻomaʻamaʻa wela o ka pā tungsten he ʻekolu mau pae: ka hoʻomehana, ka insulation, a me ka hoʻomaha. ʻO nā ʻanuʻu kikoʻī penei:
Hoʻomaʻamaʻa: E kau i ka pā tungsten i loko o ka umu wela a hoʻokiʻekiʻe i ka mahana i ka pae i makemake ʻia ma o ka hoʻomehana uila, ka hoʻomehana kinoea, a me nā ʻano hana ʻē aʻe. I ka wā o ka hoʻomehana ʻana, he mea nui ia e hoʻomalu i ka mahana a me ka wikiwiki o ka hoʻomehana ʻana e pale i ka overheating a i ʻole ka overheating localized.
Insulation: Ma hope o ka pau ʻana o ka pae hoʻomehana, pono e mālama ʻia ka pā tungsten i loko o kahi pae wela mau e hoʻopau ai i ke kaʻina hana hoʻololi a me ke kaʻina diffusion element alloy. Pono e hoʻoholo ʻia ka manawa insulation e like me nā koi kikoʻī, a maʻamau pono e mālama i ka paʻa o ka mahana no kekahi manawa.
Hoʻoluʻu: Ma hope o ka pau ʻana o ka hoʻomehana ʻana a me ka insulation, pono e hoʻomaha ʻia ka pā tungsten. E like me nā koi kikoʻī, hiki ke koho ʻia ka hoʻoluʻu kūlohelohe, ka hoʻoheheʻe ʻana o ka ea, a i ʻole ka hoʻoheheʻe wai. I ka wā o ke kaʻina hoʻoluʻu, pono e uku ʻia i ka mālama ʻana i ka nui o ka hoʻoluʻu e pale aku i nā hemahema e like me nā māwae a me nā deformations.
Ka nānā ʻana i ke ʻano: ʻike ʻia ka ʻili o ka pā tungsten e nā mea ʻike a i ʻole nā mea hana e nānā ai i nā hemahema e like me nā māwae, pores, inclusions, etc.
Nānā Manaʻo: E hoʻohana i nā mea hana e ana i nā ana o nā papa tungsten, me ka mānoanoa, ka laulā, ka lōʻihi, a me nā mea ʻē aʻe, e hōʻoia i ka hoʻokō ʻana o nā ana i nā koi.
Ka ho'āʻo hana: E hana i nā hoʻokolohua hana mechanical ma nā papa tungsten, e like me ka paʻakikī, ka ikaika tensile, ka ikaika hua, a me nā mea'ē aʻe, e hōʻoia i ka pono o kā lākou mau mea hana i nā koi.
Ka ʻike ʻana i ka haku mele: Ma ka hoʻohana ʻana i ka loiloi kemika a i ʻole nā ʻano loiloi spectral, ʻike ʻia ka ʻike o nā mea like ʻole i nā pā tungsten e hōʻoia i ka hoʻokō ʻana i nā koi.
Ka mana kaʻina hana: E hoʻomalu pono i ka hoʻoheheʻe ʻana, ka ʻōwili ʻana, annealing a me nā kaʻina hana hana ʻē aʻe o nā papa tungsten e hōʻoia i ka maikaʻi o nā papa tungsten i hana ʻia.
Pūnaehana hoʻokele maikaʻi: E hoʻokumu i kahi ʻōnaehana hoʻokele maikaʻi e nānā pono i nā ʻano āpau o ka hana ʻana o ka pā tungsten, ka hana ʻana, ka nānā ʻana, a me nā mea ʻē aʻe.
Ma o nā ʻano i luna aʻe, hiki ke hoʻokō ʻia ka nānā ʻana i ka maikaʻi a me ka mālama ʻana i nā papa tungsten e hōʻoia i ko lākou maikaʻi a me ka hana e hoʻokō i nā koi, a me ka hoʻomaikaʻi ʻana i ka hilinaʻi a me ka paʻa o nā huahana.
