He ʻano lubricant paʻa kūlohelohe ka ʻōpala Graphite me kahi ʻano papa, waiwai nui i nā kumuwaiwai a makepono hoʻi. Loaʻa i ka Graphite ke aniani piha, ka ʻōpala lahilahi, ka paʻakikī maikaʻi, nā waiwai kino a me nā kemika maikaʻi loa, ke kūpaʻa wela kiʻekiʻe maikaʻi, ka conductivity uila, ka conductivity wela, ka lubrication, ka plasticity a me ke kūpaʻa waikawa a me ka alkali.
Wahi a ke kūlana aupuni GB/T 3518-2008, hiki ke hoʻokaʻawale ʻia ka ʻōpala i ʻehā mau māhele e like me ka nui o ke kalapona paʻa. Wahi a ka nui o nā ʻāpana a me ka nui o ke kalapona paʻa, ua māhele ʻia ka huahana i 212 mau lama.
1. ʻO ka graphite maʻemaʻe kiʻekiʻe (ʻoi aku ka nui o ke kalapona paʻa ma mua o 99.9%) e hoʻohana nui ʻia e like me ka mea sila graphite maʻalahi, ma kahi o ka ipu hoʻoheheʻe platinum no ka hoʻoheheʻe ʻana i nā reagents kemika a me nā mea kumu lubricant, a pēlā aku.
2. Hoʻohana nui ʻia ka graphite kalapona kiʻekiʻe (ʻo ka nui o ke kalapona paʻa 94.0% ~ 99.9%) no nā refractories, nā mea kumu lubricant, nā mea palaki, nā huahana kalapona uila, nā mea pila, nā mea penikala, nā mea hoʻopihapiha a me nā uhi, a pēlā aku.
3. ʻO ka graphite kalapona waena (me ka ʻike kalapona paʻa o 80% ~ 94%) e hoʻohana nui ʻia no nā ipu hoʻoheheʻe, nā refractories, nā mea hoʻolei, nā uhi hoʻolei, nā mea maka penikala, nā mea maka pila a me nā dyes, a pēlā aku.
4. Hoʻohana nui ʻia ka graphite kalapona haʻahaʻa (ʻoi aku ka nui o ke kalapona paʻa ma mua o 50.0% ~ 80.0%) no ka hoʻolei ʻana i nā uhi.
No laila, ʻo ka pololei o ka hoʻāʻo ʻana o ka ʻike kalapona paʻa e pili pono ana i ke kumu hoʻoholo o ka māka ʻana a me ka hoʻokaʻawale ʻana o ka flake graphite. Ma ke ʻano he ʻoihana holomua i ka hana ʻana a me ka hana ʻana o ka Laixi flake graphite, he kuleana ko Furuite Graphite e hoʻomaikaʻi mau i kona hiki ke hana a me ka ʻike a hāʻawi i nā mea kūʻai aku me nā huahana kiʻekiʻe. Hoʻokipa ʻia nā mea kūʻai aku e nīnau a kipa aku a kūkākūkā.
