Alakaʻi Uila Graphite

Nā ʻElekoda Graphite

Hoʻohana nui ʻia nā electrodes graphite i ka hana kila o ka umu arc uila no ka mea he waiwai ko lākou o ka conductivity uila kiʻekiʻe.

Wehewehena

ʻO nā electrodes graphite wale nō nā huahana i loaʻa i kēia manawa me nā pae kiʻekiʻe o ka conductivity uila a me ka hiki ke hoʻomau i nā pae kiʻekiʻe loa o ka wela i hana ʻia i kēia ʻano koi. Hoʻohana ʻia lākou e hoʻomaʻemaʻe i ke kila i loko o nā umu ladle a me nā kaʻina hana hoʻoheheʻe ʻē aʻe. Hana kēia mau mea ma ke ʻano he alakaʻi uila i loko o ka umu, e hana ana i ka wela lawa e hoʻoheheʻe i ka metala ʻōpala, ka hao hao a i ʻole nā mea maka ʻē aʻe i hoʻohana ʻia e hana i ke kila a i ʻole nā metala ʻē aʻe. I loko o kahi umu maʻamau e hoʻohana ana i ke au alternating a hana ma kahi helu maʻamau o nā pōʻaiapuni hana i kēlā me kēia lā, hoʻopau piha ʻia kekahi o nā electrodes ʻeiwa (e koi ana i ka hoʻohui ʻana o kahi electrode hou), ma ka awelika, i kēlā me kēia ʻewalu a ʻumi mau hola hana. ʻO ka nui maoli o ka hoʻohana ʻana a me ka hoʻohui ʻana o nā electrodes no kahi umu kikoʻī e pili nui ana i ka pono a me ka huahua o ka umu.
