Hoʻolauna i ka graphite flexible felt
Loaʻa i ka graphite kiʻekiʻe nā waiwai o ka paona māmā, ka haunaele maikaʻi, ka ʻike kalapona kiʻekiʻe,pale wela kiʻekiʻe, ʻaʻohe volatilization i ka wela kiʻekiʻe,pale ʻino, liiliika hoʻoheheʻe welaa me ka paʻa kiʻekiʻe.
Loaʻa i ka huahana nā mea maikaʻi aʻe: ma hope o 1800 ~ 2500 ℃ ka mālama wela kiʻekiʻe, ʻo ka ʻokoʻa wela ma waena o nā wahi ʻelua o ka manaʻo ʻaʻole ʻoi aku ma mua o 50 ℃, no laila paʻa ka hana o ka huahana. No ka mea he hana mau ia, hiki iā ia ke hōʻoia i ka like ʻole o nā mea i manaʻo ʻia i kekahi ākea a me ka lōʻihi.
Hoʻohālikelike ʻia mekalapona manaʻomālama ʻia ma ka wela haʻahaʻa (ma lalo o 900 ℃), ua manaʻo ʻia ka graphite i mālama ʻia i ka wela kiʻekiʻe (ma luna o 2200 ℃) i kēia mau pono:
(1) ʻO ka adsorption o ka mahu wai a me nā kinoea ʻē aʻe ma ka graphite manaʻo he 2 mau kauoha o ka nui haʻahaʻa ma mua o ke kalapona i manaʻo ʻia ma ka wela haʻahaʻa. No ka nui o nā lako moku i pani ʻia e pono e hoʻomaʻemaʻe ʻia, ʻo ka maʻemaʻe o ka lewa ke kumu nui. Eia nō naʻe, ma muli o ke kiʻekiʻe adsorption o ka haʻahaʻa haʻahaʻa i mālama ʻia ke kalapona i manaʻo ʻia, paʻakikī ke hoʻomaʻemaʻe i ka moku.
(2) He ikaika ko ka graphite i ka hoʻoemi ʻana. ʻO ke ʻano o ke kalapona me ka ʻole o ka graphitization he ʻano ʻano papa hana ʻino. ʻO ka loaʻa ʻana o nā ʻano kīnā like ʻole e ʻoi aku ka nui o kona papa, a ua maʻalahi ke hoʻouka ʻia e nā ʻātoma oxygen a me ka oxidized. ʻO ka lattice maikaʻi loa a kauoha ʻia ka hoʻonohonoho ʻekolu-dimensional o ka graphite i manaʻo ʻia ma hope o ka mālama ʻana i ka wela kiʻekiʻe e hoʻemi nui i ka spacing papa a ʻaʻole maʻalahi ke hoʻouka ʻia e nā ʻātoma oxygen, no laila e hoʻonui nui ai i ka mana antioxidant.
(3) He kiʻekiʻe ka maʻemaʻe o ka graphite, a ʻoi aku ka nui o ke kalapona ma mua o 99.5%. ʻO ka maʻiʻo kalapona o ka haʻahaʻa haʻahaʻa i mālama ʻia ke kalapona ʻoi aku ka liʻiliʻi ma mua o 93%, kahi maʻalahi e hoʻohaumia i ke kaiapuni i ka umu.
Ma kahi huaʻōlelo, ʻoi aku ka maikaʻi o ka hopena o ka graphite i mālama ʻia i ka wela a ʻoi aku ka lōʻihi o ke ola ma mua o ke kalapona wela haʻahaʻa.
