Ua māhele ʻia ke graphite i ka graphite kūlohelohe a me ka graphite synthetic. Ua ʻike ka hapa nui o ka poʻe akā ʻaʻole maopopo pehea e hoʻokaʻawale ai iā lākou. He aha nā ʻokoʻa ma waena o lākou? E haʻi aku ka mea hoʻoponopono ma lalo nei iā ʻoe pehea e hoʻokaʻawale ai ma waena o nā mea ʻelua:
1. ʻAno kristal
ʻO ke kiʻi graphite kūlohelohe: Ua piha loa ka hoʻomohala ʻana o ke kristal, ʻoi aku ka nui o ke kiʻekiʻe o ka graphitization o ka flake graphite ma mua o 98%, a ʻo ke kiʻekiʻe o ka graphitization o ka graphite microcrystalline kūlohelohe ma lalo o 93%.
ʻO ke kiʻekiʻe o ka hoʻomohala ʻana o ke kristal e pili ana i ka mea maka a me ka mahana o ka mālama wela. Ma ke ʻano laulā, ʻo ke kiʻekiʻe o ka mahana mālama wela, ʻo ke kiʻekiʻe o ke kiʻekiʻe o ka graphitization. I kēia manawa, ʻo ke kiʻekiʻe o ka graphitization o ka graphite artificial i hana ʻia ma ka ʻoihana he emi ma mua o 90%.
2. ʻAno hoʻonohonoho
ʻO ka graphite flake kūlohelohe: He kristal hoʻokahi ia me kahi ʻano maʻalahi a he mau kīnā crystallographic wale nō (e like me nā hemahema kiko, nā dislocations, nā hewa stacking, a me nā mea ʻē aʻe), a hōʻike i nā ʻano anisotropic ma ka pae macroscopic. He liʻiliʻi nā hua o ka graphite microcrystalline kūlohelohe, ua hoʻonohonoho pono ʻole ʻia nā hua, a aia nā pores ma hope o ka wehe ʻana i nā haumia, e hōʻike ana i ka isotropy ma ka pae macroscopic.
ʻO ka graphite artificial: Hiki ke manaʻo ʻia he mea multi-phase, me ka pae 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 mea hoʻopaʻa lanahu tar i kāʻei ʻia a puni nā ʻāpana, ka hōʻiliʻili ʻāpana a i ʻole ka pitch lanahu tar. ʻO nā pores i hoʻokumu ʻia e ka mea hoʻopaʻa ma hope o ka mālama wela, a pēlā aku.
3. ʻAno kino
ʻO ke graphite kūlohelohe: aia maʻamau i ke ʻano o ka pauka a hiki ke hoʻohana wale ʻia, akā hoʻohana pinepine ʻia ia me ka hui pū ʻana me nā mea ʻē aʻe.
ʻO ka graphite artificial: Nui nā ʻano, me ka pauka, ka fiber a me ka poloka, ʻoiai ʻo ka graphite artificial i ke ʻano haiki he poloka maʻamau, pono e hana ʻia i loko o kahi ʻano i ka wā e hoʻohana ʻia ai.
4. Nā waiwai kino a me nā kemika
Ma ke ʻano o nā waiwai kino a me nā kemika, loaʻa i ka graphite kūlohelohe a me ka graphite hana nā mea like a me nā ʻokoʻa i ka hana. No ka laʻana, ʻo ka graphite kūlohelohe a me ka graphite hana 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 nā ʻāpana, ʻo ka graphite flake kūlohelohe ka mea maikaʻi loa i ka hana hoʻoili wela a me ka conductivity uila, ukali ʻia e ka graphite microcrystalline kūlohelohe a me ka graphite hana. haʻahaʻa loa. Loaʻa i ka graphite ka lubricity maikaʻi a me kekahi plasticity. ʻO ka hoʻomohala kristal o ka graphite flake kūlohelohe ua piha loa, he liʻiliʻi ka coefficient 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, ukali ʻia e ka graphite hana. ʻilihune.
ʻO ka hana nui a Qingdao Furuite Graphite i ka pauka graphite maoli maʻemaʻe, ka pepa graphite, ka waiū graphite a me nā huahana graphite ʻē aʻe. Hoʻopaʻa ka ʻoihana i ka hōʻaiʻē e hōʻoia i ke kiʻekiʻe o nā huahana. Welina nā mea kūʻai aku e hoʻokaʻaʻike mai iā mākou.
