ʻO ka Power Tools graphite Carbon brush ka mea i haku ʻia me ke kalapona, he mea pale wela kiʻekiʻe, a hiki i kona helu hoʻoheheʻe ʻana i 3652°C. Me kēia kiʻekiʻe wela kū'ē hiʻona, graphite hiki ke kaʻina hana i loko o ka kiʻekiʻe wela kū'ē i kemika ipu crucible.The conductivity o graphite mea maikai loa, oi aku ma mua o ka nui metala, haneri o na manawa o ka mea ole-metala, no laila, ua hana ia i conductive wahi e like me. e like me nā electrodes a me nā pulupulu kalapona.

Hoʻohana nui ʻia nā pulupulu kalapona graphite i nā lako uila uila. Hoʻohana ʻia lākou e hoʻouna i nā hōʻailona a i ʻole ka ikehu i nā ʻāpana paʻa a me nā ʻāpana o kekahi mau kaʻa a i ʻole nā mea hana. He ʻehā ke ʻano, a hoʻokomo ʻia ka uea metala i ka pūnāwai. ʻO ka pulupulu kalapona ʻO kahi ʻano hoʻopili hoʻoheheʻe, no laila maʻalahi ke ʻaʻahu a pono e hoʻololi a hoʻomaʻemaʻe mau.
ʻO ke ʻano o loko o ka graphite e kōkua i nā pulupulu kalapona i ka lubricity maikaʻi.
