Pehea e hoʻokaʻawale ai i ka graphite maoli a me ka graphite artificial

Hoʻokaʻawale ʻia ka graphite i ka graphite maoli a me ka graphite synthetic. ʻIke ka hapa nui o ka poʻe akā ʻaʻole ʻike i ka ʻokoʻa. He aha nā ʻokoʻa ma waena o lākou? Na ka mea hoʻoponopono ma lalo nei e haʻi iā ʻoe pehea e hoʻokaʻawale ai i waena o nā mea ʻelua:

1. ʻO ka hana aniani
ʻO ka graphite kūlohelohe: Ua piha ka hoʻomohala ʻana o ka kristal, ʻoi aku ka nui o ka graphitization o ka flake graphite ma mua o 98%, a ʻo ka degere o ka graphitization o ka microcrystalline graphite maoli ma lalo o 93%.
Artificial graphite: ʻO ke kiʻekiʻe o ka hoʻomohala ʻana i ke aniani e pili ana i ka mea maka a me ka mahana mālama wela. ʻO ka ʻōlelo maʻamau, ʻoi aku ka kiʻekiʻe o ka wela wela, ʻoi aku ka kiʻekiʻe o ke kiʻekiʻe o ka graphitization. I kēia manawa, ʻoi aku ka liʻiliʻi o ka graphitization o ka graphite artificial i hana ʻia ma ka ʻoihana ma mua o 90%.
2. Hoʻonohonoho hoʻonohonoho
ʻO ka graphite flake maoli: He aniani hoʻokahi me kahi ʻano maʻalahi a loaʻa nā hemahema crystallographic wale nō (e like me nā hemahema kikoʻī, dislocations, hoʻopaʻa hewa, etc.), a hōʻike i nā hiʻohiʻona anisotropic ma ka pae macroscopic. He liʻiliʻi nā hua o ka microcrystalline graphite maoli, ua hoʻonohonoho pono ʻia nā kīʻaha, a aia nā pores ma hope o ka wehe ʻana o nā haumia, e hōʻike ana i ka isotropy ma ka pae macroscopic.
ʻO ka graphite artificial: Hiki ke noʻonoʻo ʻia ma ke ʻano he mea nui-phase, me ka māhele graphite i hoʻololi ʻia mai nā ʻāpana carbonaceous e like me ka petroleum coke a i ʻole pitch coke, ka pae graphite i hoʻololi ʻia mai ka binder tar lanahu i hoʻopili ʻia a puni nā ʻāpana, ka hōʻiliʻili ʻana a i ʻole ka pitch tar pitch. ʻO nā pores i hana ʻia e ka binder ma hope o ka mālama ʻana i ka wela, etc.
3. ʻAno kino
ʻO ka graphite kūlohelohe: aia ma ke ʻano o ka pauka a hiki ke hoʻohana wale ʻia, akā hoʻohana pinepine ʻia me nā mea ʻē aʻe.
Artificial graphite: Nui nā ʻano, me ka pauka, fiber a me ka poloka, ʻoiai ʻo ka graphite artificial ma ke ʻano haiki he poloka ia, pono e hana ʻia i kekahi ʻano ke hoʻohana ʻia.
4. Ka waiwai kino a me ke kemika
Ma ke ano o ke kino a me ka kemika, graphite maoli a me ka graphite artificial he mau mea like a me ka like ole o ka hana. No ka laʻana, ʻo ka graphite maoli a me ka graphite artificial he mau alakaʻi maikaʻi o ka wela a me ka uila, akā no nā pauka graphite o ka maʻemaʻe like a me ka nui o ka nui, ʻo ka graphite flake maoli ka maikaʻi loa o ka hoʻoili wela a me ka conductivity uila, a ukali ʻia e ka microcrystalline graphite a me ka graphite artificial. . haahaa. Loaʻa i ka graphite ka lubricity maikaʻi a me ka plasticity. ʻO ka hoʻomohala ʻana o ke aniani o ka graphite flake maoli he mea paʻa, liʻiliʻi ka ʻāpana friction, ʻoi aku ka maikaʻi o ka lubricity, a ʻo ka plasticity ka mea kiʻekiʻe loa, ukali ʻia e ka graphite crystalline dense a me ka graphite cryptocrystalline, a ukali ʻia e ka graphite artificial. ʻilihune.
Hoʻohana nui ʻia ʻo Qingdao Furuite Graphite i ka pauka graphite kūlohelohe maoli, pepa graphite, waiu graphite a me nā huahana graphite ʻē aʻe. Hoʻopili nui ka hui i ka hōʻaiʻē e hōʻoia i ka maikaʻi o nā huahana. Hoʻokipaʻia nā mea kūʻai e leka mai iā mākou.
