Nā kahua noi o ka pauka graphite a me ka pauka graphite hana

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 ka brick magnesium carbon a me ka 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 o ka hana kila, akā paʻakikī ke hoʻohana ʻia ka electrode i hana ʻia me ka pauka graphite kūlohelohe i loko o ka umu uila o ka hana kila.

2. ʻOihana mīkini

I ka ʻoihana mīkini, hoʻohana pinepine ʻia nā mea graphite ma ke ʻano he mau mea pale a me ka 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 reagents ʻoihana ʻē aʻe i hoʻohana ʻia. ʻO nā ʻanuʻu maʻamau o ka hoʻomākaukau ʻana penei: ma ka 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, a hana ʻia no kekahi manawa ma lalo o ka hoʻoulu mau ʻana, a laila holoi ʻia i ka neutral, centrifugal separation, dehydration a me ka vacuum drying ma 60 ℃. Loaʻa i ka pauka graphite kūlohelohe ka lubricity maikaʻi a hoʻohana pinepine ʻia ma ke ʻano he mea hoʻohui i ka ʻaila lubricating. No ka lawe ʻana i ka corrosive medium, hoʻohana nui ʻia nā apo piston, nā apo sila a me nā bearings i hana ʻia me ka pauka graphite artificial, me ka hoʻohui ʻole ʻana i ka ʻaila lubricating i ka wā e hana ana. Hiki ke hoʻohana ʻia ka pauka graphite kūlohelohe a me nā composites resin polymer i nā kahua i luna, akā ʻaʻole maikaʻi ka pale ʻana o ke kapa 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, ka permeability haʻahaʻa, a hoʻohana nui ʻia i ka ʻoihana kemika e hana i nā mea hoʻololi wela, ka pahu hana, ka hale kiaʻi omo, ka 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 ka pauka graphite artificial.

Me ka hoʻomohala ʻana o ka ʻenehana noiʻi, ʻaʻole hiki ke ana ʻia ka manaʻolana noi o ka pauka graphite artificial. I kēia manawa, ʻo ka hoʻohana ʻana i ka graphite kūlohelohe ma ke ʻano he mea maka e hoʻomohala ai i nā huahana graphite artificial hiki ke manaʻo ʻia ʻo ia 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 kōkua maka 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 e hoʻokō ai i kēia pahuhopu, ʻo ia ka hoʻohana piha ʻana i ke ʻano a me nā ʻano o ka pauka graphite kūlohelohe, a e hana i nā huahana graphite artificial me ke ʻano kūikawā, ka hana a me ka hoʻohana ʻana e ka ʻenehana kūpono, ke ala a me ke ʻano hana.
