Hiki ke hoʻohanaʻia ka graphite e like me ke alakaʻi penikala, ka puaʻa, ka polishing agent, ma hope o ka hana kūikawā, hiki ke hanaʻia i nāʻano mea kūikawā likeʻole, i hoʻohanaʻia i nāʻoihanaʻoihana pili. No laila he aha ka hoʻohana pono ʻana o ka pauka graphite? Eia kahi kānana no ʻoe.
He paʻa kemika maikaʻi ko ka pauka Graphite. ʻO ka toner pōhaku ma hope o ka hana kūikawā, loaʻa nā ʻano o ka corrosion resistance maikaʻi, maikaʻi thermal conductivity, haʻahaʻa haʻahaʻa, hoʻohana nui ʻia i ka hana ʻana o ka mea hoʻololi wela, ka pahu hopena, condenser, hale kiaʻi puhi, absorption tower, cooler, heat, filter, pump equipment. Hoʻohana nui ʻia i ka petrochemical, hydrometallurgy, acid and alkali production, synthetic fiber, pepa a me nā ʻoihana ʻē aʻe, hiki ke mālama i ka nui o nā mea metala.
No ka hoʻolei ʻana, aluminika hoʻolei ʻana, hoʻoheheʻe ʻia a me nā mea metallurgical kiʻekiʻe: ma muli o ka liʻiliʻi o ka graphite thermal expansion coefficient, a hiki ke hoʻololi i ka hopena thermal, hiki ke hoʻohana ʻia e like me ke aniani mole, me ka hoʻohana ʻana i ka graphite ʻeleʻele metala hoʻolei ʻana i ka nui precision, maʻemaʻe ʻili a kiʻekiʻe. hua, ʻaʻole hiki ke hoʻohana ʻia ka hana ʻana a i ʻole ka hana liʻiliʻi, i mea e mālama ai i ka nui o ka metala. ʻO ka hana ʻana i ke kaʻina hana metala ka pauka cement carbide, hana mau ʻia mai nā mea graphite, i hoʻopaʻa ʻia me nā ipu porcelain. ʻO nā kapuahi ulu kristal, e like me ka monocrystalline silicon, nā moku hoʻomaʻemaʻe kūloko, nā mea hoʻopaʻa paʻa, nā mea hoʻomehana induction, etc. Eia kekahi, hiki ke hoʻohana ʻia ka graphite e like me ka pahu hoʻoheheʻe ʻana i ka graphite insulation board a me ke kumu, kiʻekiʻe kiʻekiʻe o ka wela o ka umu ahi, ka pā, ka pā, ka lattice a me nā mea ʻē aʻe.
Hiki i ka Graphite ke pale i ka hoʻonui ʻia ʻana o ka paila, hōʻike ʻia nā hōʻike ʻāpana kūpono e hoʻohui i kahi nui o ka pauka graphite i loko o ka wai (ma kahi o 4 ~ 5 grams no ka wai) hiki ke pale i ka hoʻonui ʻana i ka ʻili o ka paila. Eia kekahi, hiki ke hoʻohana ʻia ka graphite i nā kapuahi metala, nā hale, nā alahaka a me nā paipu.
Eia kekahi, graphite a aniani paha a me ka pepa i loko o ka ʻoihana māmā polish a me ka rust inhibitor, ʻo ia ka hana ʻana i ka penikala, ka inika, ka pena ʻeleʻele, ka inika a me ka daimana synthetic, nā mea waiwai pono ʻole. He mea mālama ikehu maikaʻi loa ia a me ka mālama ʻana i ke kaiapuni, ua hoʻohana ʻo ʻAmelika iā ia ma ke ʻano he pākahi kaʻa. Me ka hoʻomohala ʻana o ka ʻepekema hou a me ka ʻenehana a me ka ʻoihana, hoʻomau ka hoʻohana ʻana i ka graphite e hoʻonui, ua lilo i mea waiwai nui i ka ʻenehana kiʻekiʻe o nā mea hana hou, noho i kahi kūlana koʻikoʻi i ka ʻoihana aupuni.
Hoʻohana ʻia i ka ʻoihana ikehu atomic a me ka ʻoihana pale aupuni: ʻo ka graphite pauda he neutron positron maikaʻi i hoʻohana ʻia i nā reactors atomic, ʻoi aku ka hoʻohana ʻana o ka uranium graphite reactor i kahi reactor atomic. E like me ka mana i hoʻohana ʻia e like me ka deceleration mea no ka nuklea reactor, pono ke kiʻekiʻe i ka helu heheʻe, kūpaʻa a me ke kūpaʻa corrosion, a hiki i ka pauka graphite ke hoʻokō i nā koi i luna. ʻO ka graphite i hoʻohana ʻia i loko o nā mea hoʻoheheʻe atomika he maʻemaʻe ʻaʻole pono e ʻoi aku ka haumia ma mua o ʻumi mau ʻāpana o ka miliona. ʻO ka mea nui, pono e emi ka ʻike o ka polone ma mua o 0.5PPM. I ka ʻoihana pale, hoʻohana pū ʻia ka pauka graphite e hana i nā nozzles no nā rockets solid-fuel, cones ihu no nā missiles, nā ʻāpana no nā lako hoʻokele lewa, ka insulation wela, a me nā mea pale radiation.
