Hiki ke hoʻohana ʻia ka pauda graphite e like me ka penikala, no laila no ke aha e hoʻohana ʻia ai ka pauda graphite e like me ka penikala? Maopopo anei iā ʻoe? E heluhelu pū me ka mea hoʻoponopono!
ʻO ka mea mua, he palupalu a maʻalahi ka pauka graphite e ʻokiʻoki, a he lubricious a maʻalahi hoʻi ke kākau ʻana i ka pauka graphite; No ke aha e hoʻohana ʻia ai ka penikala 2B i ka hoʻokolokolo puka komo ʻana, pono e hoʻohana ʻia kona conductivity. ʻO ka lua, ma ke ʻano o nā waiwai kemika, ua haku ʻia ka pauka graphite me ka element C, a ʻo nā waiwai kemika o ka element C e paʻa mau i ka lumi wela, no laila me ka hoʻohana ʻana i ka penikala graphite pauka e hoʻopaʻa i nā faila hiki ke mālama i kahi manawa lōʻihi.
Loaʻa i ka graphite pauda nā waiwai kūikawā ma muli o kāna hana kūikawā:
1) Palena wela kiʻekiʻe: ʻO ka pauka Graphite he wahi heheʻe o 3850 50 ℃ a me kahi paila o 4250 ℃. ʻOiai ua puhi ʻia e ka wela wela kiʻekiʻe loa, ʻuʻuku loa kona pohō kaumaha a me ka hoʻonui ʻana i ka wela. Hoʻonui ka ikaika o ka pauka graphite me ka piʻi ʻana o ka mahana, a pālua ka ikaika o ka pauka graphite ma 2000 ℃.
2) Conductivity a me thermal conductivity: ʻO ka conductivity o ka pauka graphite he hoʻokahi haneli mau manawa kiʻekiʻe ma mua o nā ores nonmetallic maʻamau. ʻOi aku ka hoʻoili wela ma mua o nā mea metala e like me ke kila, ka hao a me ke kēpau. Ke emi nei ka thermal conductivity me ka piʻi ʻana o ka mahana, a i ka wela kiʻekiʻe loa, lilo ka pauka graphite i insulator. Hiki i ka pauda graphite ke hoʻokele i ka uila no ka mea, ʻo kēlā me kēia kalapona kalapona i loko o ka pauda graphite wale nō e hana i ʻekolu mau paʻa covalent me nā ʻātoma kalapona ʻē aʻe, a paʻa mau kēlā me kēia kalapona kalapona i hoʻokahi electron manuahi e hoʻoili i ka uku.
3) Lubricity: ʻO ka waiwai lubricating o ka pauka graphite e pili ana i ka nui o nā unahi pauka graphite. ʻO ka ʻoi aku ka nui o ka unahi, ʻoi aku ka liʻiliʻi o ka friction coefficient a ʻoi aku ka maikaʻi o ka waiwai lubricating.
4) Paʻa kemika: He kūpaʻa kemika maikaʻi ka pauka Graphite i ka mahana o ka lumi, a hiki ke pale aku i ka ʻakika, alkali a me nā mea hoʻoheheʻe kūlohelohe.
5) Plasticity: He paʻakikī maikaʻi ka pauka Graphite a hiki ke ʻoki ʻia i loko o nā ʻāpana lahilahi.
6) ʻO ke kūpaʻa haʻalulu wela: Hiki i ka pauka Graphite ke pale i ka loli nui o ka mahana ma ka lumi wela me ka ʻole o ka pōʻino. Ke loli koke ka mahana, ʻaʻole e loli nui ka nui o ka pauda graphite a ʻaʻole hiki mai nā māwae.
E kūʻai i ka pauka graphite, hoʻokipa iā Qingdao Furuite Graphite Factory, e hāʻawi mākou iā ʻoe i ka lawelawe ʻoluʻolu, i ʻole ʻoe hopohopo!
