Pehea e koho ai i nā darts?

Nui nā ʻano pana pua ma ka mākeke, mai ke keleawe a i ka tungsten.I kēia manawa, ʻo ka mea kaulana loa ʻo tungsten nickel dart.ʻO Tungsten kahi metala kaumaha kūpono no nā pana.

Ua hoʻohana ʻia ʻo Tungsten ma Darts mai ka 1970s mua no ka mea ʻelua ʻoi kona kaumaha ma mua o ke keleawe, akā ʻo nā pana i hana ʻia me ka tungsten he hapalua wale nō ka nui o ke keleawe.ʻO ka hoʻokomo ʻana o nā pana tungsten i hoʻololi i ka pāʻani, ʻaʻole kēia he hoʻonui.Ua ʻae ʻo Tungsten darts i ʻelua mau mea pili like.I ka liʻiliʻi ʻana o nā ihe, ua ʻoi aku ke kaumaha, a ʻo nā ihe kaumaha i hoʻomaikaʻi nui i nā helu o ka mea pāʻani!

ʻO kahi pahu tungsten, ʻoi aku ke kaumaha ma mua o ke keleawe a i ʻole ka pahu plastik, e lele i ka lewa ma kahi laina pololei a me ka ikaika ʻoi aku;ʻo ia hoʻi, ʻoi aku ka liʻiliʻi o nā bounce out.No laila, ua hā'awi nā pū'ulu kaumaha i nā mea pā'ani me ka mana oi aku i ka wā o ka ho'olei 'ana a ho'oikaika i ka hui 'ana.'O ia ho'i, hiki i nā mea pā'ani dart ke ho'okō i ka hui pū 'ana o nā dart ma nā wahi li'ili'i a loa'a paha ka helu ki'eki'e loa o 180!

No ka mea he palupalu loa ka 100% tungsten, pono e hana nā mea hana i nā ʻāpana tungsten, e hui pū i ka tungsten me nā metala ʻē aʻe (ka nui o ka nickel) a me nā waiwai ʻē aʻe e like me ke keleawe a me ka zinc.Hoʻohui ʻia kēia mau mea a pau i loko o kahi ʻōpala, kaomi ʻia i kekahi mau tona o ke kaomi a hoʻomehana ʻia i loko o ka umu a ʻoi aku ma luna o 3000 ℃.A laila hana ʻia ka blank i loaʻa e hana i kahi koʻokoʻo i poni ʻia me ka ʻili maʻemaʻe.ʻO ka hope, ua hana ʻia ka pahu dart me ke ʻano makemake, ke kaumaha a me ka paʻa (knurling) me ke koʻokoʻo.

ʻO ka hapa nui o nā darts tungsten e hōʻike ana i ka pākēneka o ka ʻike tungsten, a ʻo ka laulā maʻamau ʻo 80-97%.ʻO ka mea maʻamau, ʻoi aku ka kiʻekiʻe o ka tungsten content, ʻoi aku ka lahilahi o ka dart e hiki ke hoʻohālikelike ʻia me ke keleawe dart like.ʻO ka paona, ke ʻano a me ka hoʻolālā ʻana o nā pana pua he mau koho pilikino a pau, ʻo ia ke kumu e hiki ai iā mākou ke ʻike i nā ʻano paona a me nā hoʻolālā i kēia manawa.ʻAʻohe mea ʻoi aku ka maikaʻi, no ka mea, ʻo kēlā me kēia mea hoʻolei i kona makemake ponoʻī.
