E like me kā kākou e ʻike nei, he kiʻekiʻe nā ʻano maikaʻi o ka graphite i hiki ʻole i nā mea metala ʻē aʻe ke pani. Ma ke ʻano he mea makemake nui ʻia, he nui nā ʻano huikau o nā mea electrode graphite i ke koho maoli ʻana o nā mea. Nui nā kumu no ke koho ʻana i nā mea electrode graphite, akā aia nā kumu nui ʻehā:
No nā mea me ka nui like o ka ʻāpana like, ʻoi aku ka haʻahaʻa o ka ikaika a me ka paʻakikī o nā mea me ka resistivity haʻahaʻa ma mua o nā mea me ka resistivity kiʻekiʻe. ʻO ia hoʻi, e ʻokoʻa ka wikiwiki o ka hoʻokuʻu ʻana a me ka pohō. No laila, he mea nui loa ka resistivity intrinsic o ka mea electrode graphite no ka hoʻohana pono ʻana. Pili pono ke koho ʻana i nā mea electrode i ka hopena o ka hoʻokuʻu ʻana. I kahi nui, ʻo ke koho ʻana i nā mea e hoʻoholo ai i nā kūlana hope o ka wikiwiki o ka hoʻokuʻu ʻana, ka pololei o ka mīkini a me ka ʻili.
I loko o ka ʻoihana graphite kūikawā, ʻo ke ʻano hoʻāʻo paʻakikī maʻamau ka Shore hardness technique, nona ke kumu hoʻāʻo he ʻokoʻa ia mai ka metala. ʻOiai i ko mākou ʻike subconscious o ka graphite, ua manaʻo nui ʻia he mea palupalu. Akā, hōʻike ka ʻikepili hoʻāʻo maoli a me ka noi ʻana he ʻoi aku ka paʻakikī o ka graphite ma mua o nā mea metala. Ma muli o ke ʻano papa o ka graphite, he hana ʻoki maikaʻi loa ia i ke kaʻina hana ʻoki. ʻO ka ikaika ʻoki he 1/3 wale nō o ka mea keleawe, a maʻalahi ka lawelawe ʻana i ka ʻili mīkini.
Eia nō naʻe, ma muli o kona paʻakikī kiʻekiʻe, e ʻoi aku ka nui o ke komo ʻana o ka mea hana ma mua o nā mea ʻoki metala i ka ʻoki ʻana. I ka manawa like, ʻo ka mea me ka paʻakikī kiʻekiʻe he kaohi maikaʻi loa i ka nalowale o ka hoʻokuʻu ʻana. No laila, ʻo ka paʻakikī o ke kahakai o ka mea electrode graphite kekahi o nā pae koho o ka mea electrode graphite.
A laila aia ka ikaika flexural o nā mea electrode graphite. ʻO ka ikaika flexural o nā mea electrode graphite ka hōʻike pololei o ka ikaika o nā mea, e hōʻike ana i ka compactness o ke ʻano kūloko o nā mea. ʻO ka mea me ka ikaika kiʻekiʻe he kūpaʻa maikaʻi loa i ka hoʻokuʻu ʻana. No ka electrode me ka pololei kiʻekiʻe, pono e koho ʻia ka mea me ka ikaika maikaʻi e like me ka hiki.
ʻO ka mea hope loa, ʻo ke anawaena awelika o nā ʻāpana o nā mea electrode graphite, ʻo ke anawaena awelika o nā ʻāpana o nā mea electrode graphite e pili pololei ana i ke kūlana hoʻokuʻu o nā mea. ʻO ka liʻiliʻi o ka nui awelika o ka ʻāpana, ʻoi aku ka like o ka hoʻokuʻu ʻana, ʻoi aku ka paʻa o ke kūlana hoʻokuʻu a ʻoi aku ka maikaʻi o ka maikaʻi o ka ʻili. ʻO ka nui o ka nui o ka ʻāpana, ʻoi aku ka wikiwiki o ka wikiwiki o ka hoʻokuʻu ʻana a ʻoi aku ka liʻiliʻi o ka nalowale o ka roughing. ʻO ke kumu nui, ʻo ia ka loli o ka ikehu hoʻokuʻu me ka ikaika o kēia manawa i ka wā o ke kaʻina hana hoʻokuʻu. Eia nō naʻe, ʻokoʻa ka hoʻopau ʻana o ka ʻili ma hope o ka hoʻokuʻu ʻana me ka loli o nā ʻāpana.
Hiki i nā electrodes graphite ke koho mua o nā mea i ka ʻoihana. No ka mea he mau pono kīnā ʻole nā electrodes graphite, ʻo ke koho pololei ʻana o nā electrodes graphite a me ke koho ʻana i nā hui kūpono o nā electrodes graphite ke kī.
