kahua noi graphite

Ma ke ʻano he mineral maʻamau o ke kalapona, pili pili ka graphite i ko mākou ola, a ʻo nā kānaka maʻamau he penikala maʻamau, nā lāʻau kalapona maloʻo a pēlā aku. Eia nō naʻe, he hoʻohana koʻikoʻi ka graphite i ka ʻoihana koa, nā mea refractory, ʻoihana metallurgical, ʻoihana kemika a pēlā aku.

Loaʻa i ka Graphite nā ʻano metala a me nā mea ʻole: graphite ma ke ʻano he alakaʻi maikaʻi o ka thermoelectricity e hōʻike ana i nā ʻano metala; ʻO nā hiʻohiʻona non-metallic ka pale wela kiʻekiʻe, ke kūpaʻa wela kiʻekiʻe, ka inertness kemika a me ka lubricity, a ʻo kona hoʻohana ʻana he ākea loa.

kahua noi nui
1, mea refractory
I ka ʻoihana metallurgical, hoʻohana ʻia ia ma ke ʻano he mea refractory a me kahi mea pale no ka ingot kila. Ma muli o ka graphite a me kāna mau huahana i nā waiwai o ke kūpaʻa wela kiʻekiʻe a me ka ikaika kiʻekiʻe, hoʻohana ʻia ia i ka ʻoihana metallurgical e hana i ka graphite crucible, ka uhi ʻana o ka umu kila, ka pale pale a me ka hoʻolei mau ʻana.

2, oihana hoolei metala
Ke kila a me ka hoʻolei ʻana: Hoʻohana ʻia ka graphite ma ke ʻano he carburizer i ka ʻoihana hana kila.
I ka hoʻolei ʻana, hoʻohana ʻia ka graphite no ka hoʻolei ʻana, ke one, nā mea hoʻoheheʻe ʻia: ma muli o ka liʻiliʻi liʻiliʻi o ka hoʻonui ʻana o ka wela o ka graphite, ka hoʻohana ʻana i ka graphite e like me ka hoʻolei ʻana i ka pena, pololei ka nui o ka hoʻolei ʻana, maʻemaʻe ka ʻili, nā māwae a me nā pores. hoemi, a nui ka hua. Eia kekahi, hoʻohana ʻia ka graphite i ka hana ʻana i ka pauka metallurgy, superhard alloys; Ka hana ʻana o nā huahana kalapona.

3. ʻOihana Kemika
He paʻa kemika maikaʻi ka graphite. Loaʻa i ka graphite i hana kūikawā nā ʻano o ka pale ʻana i ka corrosion, maikaʻi thermal conductivity a me ka haʻahaʻa permeability. ʻO ka hoʻohana ʻana i ka graphite e hana i nā paipu graphite hiki ke hōʻoia i ka hopena kemika maʻamau a hoʻokō i nā pono o ka hana ʻana i nā kemika maʻemaʻe kiʻekiʻe.

4, ʻOihana uila a me ka uila
Hoʻohana ʻia i ka hana ʻana o ka micro-powder graphite electrode, brush, battery, lithium battery, fuel cell positive electrode conductive material, anode plate, electric rod, carbon tube, graphite gasket, kelepona ʻāpana, rectifier positive electrode, electromagnetic shielding conductive plastics, wela nā mea hoʻololi a me ka uhi ʻana o ka paipu kiʻi TV. I waena o lākou, hoʻohana nui ʻia ka electrode graphite no ka hoʻoheheʻe ʻana i nā ʻano mea like ʻole; Eia kekahi, hoʻohana ʻia ka graphite e like me ka cathode o nā cell electrolytic no ka electrolysis o nā metala e like me ka magnesium a me ka alumini.
I kēia manawa, hoʻohana nui ʻia nā inika mōʻalihaku fluorine (CF, GF) i nā mea uila uila kiʻekiʻe, ʻoi aku ka CF0.5-0.99 fluorine fossil inks, ʻoi aku ka maikaʻi no ka hana ʻana i nā mea anode no nā ʻenekini kiʻekiʻe, a me ka miniaturizing batteries.

5. ʻO ka ikehu Atomic, aerospace a me nā ʻoihana pale
He kiʻekiʻe ka hoʻoheheʻe ʻana o ka Graphite, kūpaʻa, ka pale ʻana i ka corrosion a me ke kūpaʻa maikaʻi ʻana i nā kukui A a me ka hana neutron deceleration, i hoʻohana ʻia i ka ʻoihana nuklea o nā mea graphite i kapa ʻia ʻo nuclear graphite. Aia nā neutron moderators no ka atomic reactors, reflectors, hot cylinder ink for isotope production, spherical graphite for high temperature gas cooled reactors, nuclear reactor thermal parts sealing gaskets and bulk blocks.
Hoʻohana ʻia ʻo Graphite i nā reactors thermal a, me ka manaʻolana, nā reactors fusion, kahi hiki ke hoʻohana ʻia ma ke ʻano he neutron moderator i loko o ka wahie wahie, ma ke ʻano he mea reflector a puni ka wahie, a ma ke ʻano he mea hoʻolālā i loko o ke kumu.

Eia kekahi, ua hoʻohana ʻia ka graphite i ka hana ʻana i nā missile lōʻihi a i ʻole nā ​​​​mea hoʻolale pōhaku ākea, nā ʻāpana aerospace, insulation wela a me nā mea pale radiation, ka hana ʻana i ka wahie paʻa rocket engine huelo nozzle throat liner, etc. ka hana ʻana i nā pulupulu lele, a me nā moku mokulele DC a me nā ʻāpana lako aerospace, nā hōʻailona pili lekiō ukali a me nā mea hana conductive; I ka ʻoihana pale, hiki ke hoʻohana ʻia e hana i nā bearings no nā submarines hou, hana i ka graphite maʻemaʻe kiʻekiʻe no ka pale aupuni, nā pōkā graphite, nā cones ihu no nā mokulele stealth a me nā missiles. ʻO ka mea nui, hiki i nā pōkā graphite ke hoʻopau i ka hana o nā substations a me nā mea uila nui ʻē aʻe, a ʻoi aku ka hopena o ka lewa.

6. ʻOihana mīkini

Hoʻohana nui ʻia ʻo Graphite i ka hana ʻana i nā kaʻa kaʻa kaʻa a me nā mea ʻē aʻe a me nā lubricants kiʻekiʻe i ka ʻoihana mīkini; Ma hope o ka hana ʻia ʻana o ka graphite i loko o ka colloidal graphite a me ka fluorofossil ink (CF, GF), hoʻohana maʻamau ia ma ke ʻano he lubricant paʻa i ka ʻoihana mīkini e like me nā mokulele, nā moku, nā kaʻaahi, nā kaʻa a me nā mīkini holo kiʻekiʻe.
