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

Ua lawe mai ke ʻano o ka graphite i kahi kōkua nui i ko kākou ola. I kēia lā, e nānā kākou i nā ʻano graphite, ka graphite lepo a me ka graphite flake. Ma hope o ka nui o ka noiʻi a me ka hoʻohana ʻana, he waiwai nui ka hoʻohana ʻana o kēia mau ʻano mea graphite ʻelua. Maanei, haʻi aku ka Qingdao Furuite Graphite Editor iā ʻoe e pili ana i nā ʻokoʻa ma waena o kēia mau ʻano graphite ʻelua:

I. Graphite ʻōpala

ʻO ka graphite crystalline me nā unahi a me nā lau lahilahi, ʻo ka nui o nā unahi, ʻo ke kiʻekiʻe o ka waiwai waiwai. Hoʻolaha ʻia ka hapa nui o lākou i loko o nā pōhaku. Loaʻa iā ia kahi hoʻonohonoho kuhikuhi maopopo. Kūlike me ke kuhikuhi o ka pae. ʻO ka nui 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 nā pōhaku metamorphic kahiko (schist a me gneiss), a hiki ke ʻike ʻia ma ka ʻāpana pili ma waena o ka pōhaku igneous a me ka limestone. He ʻano papa ko ka graphite scaly, a ʻoi aku ka maikaʻi o kona lubricity, flexibility, resistance wela a me ka conductivity uila ma mua o nā graphite ʻē aʻe. Hoʻohana nui ʻia ma ke ʻano he mea maka no ka hana ʻana i nā huahana graphite maʻemaʻe kiʻekiʻe.

II. Graphite lepo

Ua kapa ʻia hoʻi ka graphite honua he graphite amorphous a i ʻole ka graphite cryptocrystalline. ʻO ke anawaena kristal o kēia graphite maʻamau he emi ma mua o 1 micron, a he hui ia o ka graphite microcrystalline, a ʻike wale ʻia ke ʻano kristal ma lalo o kahi microscope electron. ʻO kēia ʻano graphite e hōʻike ʻia e kona ʻili lepo, nele i ka luster, lubricity maikaʻi ʻole a me ke kiʻekiʻe kiʻekiʻe. Ma ke ʻano laulā 60 ~ 80%, ʻoi aku ka kiʻekiʻe o kekahi ma mua o 90%, ʻaʻole hiki ke holoi ʻia ka ore.

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