He nui nā waiwai maikaʻi loa o ka pauka graphite, no laila ua hoʻohana nui ʻia i ka metallurgy, mīkini, uila, kemika, lole, pale aupuni a me nā ʻoihana ʻē aʻe. Loaʻa i nā kahua noi o ka pauka graphite maoli a me ka pauka graphite artificial nā ʻāpana a me nā ʻokoʻa e pili ana. Hoʻolauna ka mea hoʻoponopono graphite Furuite ma lalo nei i nā kahua noi o ka pauka graphite a me ka pauka graphite artificial.
1. ʻOihana hana hao
I ka ʻoihana metallurgical, hiki ke hoʻohana ʻia ka pauka graphite kūlohelohe e hana i nā mea refractory e like me nā brick magnesia-carbon a me nā brick alumini-carbon ma muli o kona kūpaʻa maikaʻi i ka oxidation. Hiki ke hoʻohana ʻia ka pauka graphite artificial ma ke ʻano he electrode hana kila, akā paʻakikī ka hoʻohana ʻana i nā electrodes i hana ʻia me ka pauka graphite kūlohelohe i nā umu uila hana kila me nā kūlana hana paʻakikī.
2. ʻOihana mīkini
I ka ʻoihana mīkini, hoʻohana pinepine ʻia nā mea graphite ma ke ʻano he mau mea pale a me nā mea lubricating. ʻO ka mea maka mua no ka hoʻomākaukau ʻana i ka graphite hiki ke hoʻonui ʻia he graphite flake kalapona kiʻekiʻe, a me nā reagents kemika ʻē aʻe e like me ka waikawa sulfuric i hoʻopaʻa ʻia (ma luna o 98%), hydrogen peroxide (ma luna o 28%), potassium permanganate, a me nā mea ʻē aʻe he mau reagents ʻoihana āpau. ʻO nā ʻanuʻu maʻamau o ka hoʻomākaukau ʻana penei: ma kahi mahana kūpono, hoʻohui ʻia nā ʻano like ʻole o ka hopena hydrogen peroxide, graphite flake kūlohelohe a me ka waikawa sulfuric i hoʻopaʻa ʻia i nā kaʻina hana like ʻole, hana ʻia no kekahi manawa ma lalo o ka hoʻoulu mau ʻana, a laila holoi ʻia me ka wai a hiki i ka neutral, a centrifuged. Ma hope o ka dehydration, ua maloʻo ʻia ma ka vacuum ma 60 °C. He lubricity maikaʻi ka pauka graphite kūlohelohe a hoʻohana pinepine ʻia ma ke ʻano he mea hoʻohui no nā aila lubricating. Hoʻohana nui nā lako no ka lawe ʻana i ka corrosive medium i nā apo piston, nā apo sila a me nā bearings i hana ʻia me ka pauka graphite artificial, a ʻaʻole pono e hoʻohui i ka aila lubricating i ka wā o ka hana. Hiki ke hoʻohana ʻia ka pauka graphite kūlohelohe a me nā mea composite resin polymer i nā kahua i luna, akā ʻaʻole maikaʻi ke kūpaʻa ʻana o ka ʻaʻahu e like me ka pauka graphite artificial.
3. ʻOihana kemika
ʻO ka pauka graphite artificial he mau ʻano o ke kūpaʻa ʻana i ka palaho, ka conductivity thermal maikaʻi a me ka permeability haʻahaʻa. Hoʻohana nui ʻia ia i ka ʻoihana kemika e hana i nā mea hoʻololi wela, nā pahu hopena, nā hale kiaʻi omo, nā kānana a me nā lako ʻē aʻe. Hiki ke hoʻohana ʻia ka pauka graphite kūlohelohe a me nā mea hui polymer resin i nā kahua i luna, akā ʻaʻole maikaʻi ka conductivity thermal a me ke kūpaʻa corrosion e like me nā pauka graphite artificial.
Me ka hoʻomohala mau ʻana o ka ʻenehana noiʻi, ʻaʻole hiki ke ana ʻia ka manaʻolana no ka hoʻohana ʻana i ka pauka graphite artificial. I kēia manawa, ʻo ka hoʻomohala ʻana i nā huahana graphite artificial me ka graphite kūlohelohe ma ke ʻano he mea maka kekahi o nā ala koʻikoʻi e hoʻonui ai i ke kahua noi o ka graphite kūlohelohe. Ua hoʻohana ʻia ka pauka graphite kūlohelohe ma ke ʻano he mea maka kōkua i ka hana ʻana o kekahi mau pauka graphite artificial, akā ʻaʻole lawa ka hoʻomohala ʻana i nā huahana graphite artificial me ka pauka graphite kūlohelohe ma ke ʻano he mea maka nui. ʻO ke ala maikaʻi loa ia e hoʻokō ai i kēia pahuhopu ma o ka hoʻomaopopo piha ʻana a me ka hoʻohana ʻana i ke ʻano a me nā ʻano o ka pauka graphite kūlohelohe, a me ka hoʻohana ʻana i nā kaʻina hana kūpono, nā ala a me nā ʻano hana e hana ai i nā huahana graphite artificial me ke ʻano kūikawā, nā waiwai a me nā hoʻohana.
