He aha nā ʻokoʻa ma waena o smectite graphite a me flake graphite

ʻO ke ʻano o ka graphite ua kōkua nui i ko mākou ola. I kēia lā, e nānā mākou i nā ʻano o ka graphite, ka graphite honua a me ka graphite flake. Ma hope o ka nui o ka noiʻi ʻana a me ka hoʻohana ʻana, loaʻa ka waiwai hoʻohana kiʻekiʻe o kēia mau ʻano mea graphite ʻelua. Eia, hōʻike ʻo Qingdao Furuite Graphite Editor iā ʻoe e pili ana i nā ʻokoʻa ma waena o kēia mau ʻano graphite ʻelua.

I. graphite Flake

ʻO ka graphite crystalline me nā unahi a me nā lau lahilahi, ʻoi aku ka nui o nā unahi, ʻoi aku ka kiʻekiʻe o ka waiwai waiwai. Hoʻolaha ʻia ka hapa nui o lākou a hāʻawi ʻia i loko o nā pōhaku. Loaʻa iā ia kahi hoʻonohonoho kuhikuhi. Kūlike me ke kuhikuhi o ka pae. ʻO ka maʻiʻo o ka graphite he 3% ~ 10%, a hiki i ka 20%. Hoʻopili pinepine ʻia me Shi Ying, feldspar, diopside a me nā minela ʻē aʻe i loko o nā pōhaku metamorphic kahiko (schist a me gneiss), a hiki ke ʻike ʻia ma ka wahi pili ma waena o ka pōhaku igneous a me ka limestone. ʻOi aku ka maikaʻi o ka graphite scaly, a ʻoi aku ka maikaʻi o ka lubricity, ka maʻalahi, ka pale ʻana i ka wela a me ka conductivity uila ma mua o nā graphite ʻē aʻe. Hoʻohana nui ʻia e like me ka mea maka no ka hana ʻana i nā huahana graphite maʻemaʻe kiʻekiʻe.

II. graphite lepo

Kapa ʻia ka graphite like honua i ka graphite amorphous a i ʻole ka graphite cryptocrystalline. ʻO ke anawaena aniani o kēia graphite ma lalo o 1 micron, a he hui ia o ka microcrystalline graphite, a ʻike ʻia ke ʻano aniani ma lalo o kahi microscope electron. Hōʻike ʻia kēia ʻano graphite e kona ʻili honua, nele i ka luster, lubricity maikaʻi ʻole a me ka pae kiʻekiʻe. ʻO ka maʻamau 60 ~ 80%, kahi liʻiliʻi e like me ke kiʻekiʻe ma mua o 90%, ʻaʻohe hiki ke holoi ʻia.

Ma o ka kaʻana like ʻana i luna, ʻike mākou he mea pono e hoʻokaʻawale i nā ʻano ʻelua o ka graphite i ke kaʻina hana, i hiki ke koho maikaʻi ʻia nā mea waiwai, he mea nui loa ia no nā mea hana noi graphite.
