ʻO ka wehewehe kikoʻī o ka hoʻohana ʻana i nā huahana Graphite

ʻOi aku ka kiʻekiʻe o ka hoʻohana ʻana i nā huahana graphite ma mua o kā mākou i manaʻo ai, no laila he aha nā hoʻohana o nā huahana graphite a mākou i kamaʻāina ai i kēia manawa?

1、Hoʻohana ʻia e like me kahi mea conductive

I ka hoʻoheʻe ʻana i nā kila kila like ʻole, ferroalloys, a i ʻole ka hana ʻana i ka calcium carbide (calcium carbide) a me ka phosphorus melemele me ka hoʻohana ʻana i ka umu ahi arc a i ʻole ka umu ahi i hoʻopaʻa ʻia, hoʻokomo ʻia kahi au ikaika i loko o ka wahi hoʻoheheʻe o ka umu uila ma o nā electrodes kalapona electrodes - ie electrode paste) a i ʻole graphitized electrodes e hana i kahi arc, hoʻololi i ka ikehu uila i ka ikehu wela, a hoʻokiʻekiʻe i ka mahana ma kahi o 2000 degere Celsius, a laila e hoʻokō ai i nā koi o ka hoʻoheheʻe ʻana a i ʻole ka hopena.Hoʻopuka pinepine ʻia ka magnesium metala, aluminika, a me ka sodium e ka electrolysis paʻakai hoʻoheheʻe.I kēia manawa, ʻo ka anode conductive mea o ka electrolytic cell he mau electrodes graphite a i ʻole nā ​​​​electrodes baking mau (anode paste, i kekahi manawa pre baked anode).ʻO ka mahana o ka electrolysis paʻakai hoʻoheheʻe ʻia ma lalo o 1000 degere Celsius.ʻO nā mea hana anode conductive i hoʻohana ʻia i loko o ka paʻakai paʻakai electrolysis cell no ka hana ʻana i ka caustic soda (sodium hydroxide) a me ke kinoea chlorine he mau anodes graphitized.ʻO ka mea conductive no ke poʻo umu o ka umu kū'ē i hoʻohana ʻia i ka hana ʻana o ka silicon carbide hoʻohana pū kekahi i nā electrodes graphitized.Ma kahi o nā kumu i luna aʻe nei, hoʻohana nui ʻia nā huahana kalapona a me ka graphite e like me nā mea conductive i ka ʻoihana hana kaʻa e like me nā apo slip a me nā pulupulu.Eia kekahi, ua hoʻohana ʻia lākou e like me nā koʻokoʻo kalapona i nā pā maloʻo maloʻo, nā koʻokoʻo kalapona māmā arc no nā kukui ʻimi a i ʻole ka hana kukui arc, a me nā anodes i nā mea hoʻoponopono mercury.

2、Hoʻohana ʻia e like me nā mea refractory

Ma muli o ka hiki o nā huahana kalapona a me ka graphite ke kū i nā wela kiʻekiʻe a loaʻa ka ikaika kiʻekiʻe-mehana a me ka pale ʻana i ka corrosion, hiki ke kūkulu ʻia nā mea hoʻoheheʻe metallurgical he nui me nā poloka kalapona, e like me ka lalo, ka kapuahi, a me ka ʻōpū o nā kapuahi hoʻoheheʻe hao. ka uhi ʻana o nā kapuahi ferroalloy a me nā kapuahi calcium carbide, a me ka lalo a me nā ʻaoʻao o nā keena electrolytic aluminika.Nui nā kīʻaha i hoʻohana ʻia no ka hoʻoheheʻe ʻana i nā metala makamae a me nā metala graphitized i hoʻohana ʻia no ka hoʻoheheʻe ʻana i ke aniani quartz, i hana ʻia mai nā billet graphitized.ʻAʻole pono e hoʻohana ʻia nā huahana kalapona a me ka graphite e like me nā mea refractory i nā ea hoʻoheheʻe.No ka mea, hiki wawe ke kalapona a me ka graphite ma lalo o ka wela kiʻekiʻe i loko o ka lewa oxidizing.

3、Hoʻohana ʻia e like me ka corrosion-resistant structural material

ʻO nā electrodes graphitized i hoʻopili ʻia me nā resins organik a inorganic paha nā hiʻohiʻona o ke kūpaʻa corrosion maikaʻi, conductivity thermal maikaʻi, a me ka permeability haʻahaʻa.Ua ʻike ʻia kēia ʻano graphite impregnated he graphite impermeable.Hoʻohana nui ʻia ia i ka hana ʻana i nā mea hoʻololi wela like ʻole, nā tank reaction, condensers, combustion towers, absorption towers, coolers, heaters, filters, pumps, and other equipment.Hoʻohana nui ʻia ia i nā ʻoihana ʻoihana e like me ka hoʻomaʻemaʻe ʻaila, petrochemical, hydrometallurgy, acid and alkali production, synthetic fibers, papermaking, a hiki ke mālama i ka nui o nā mea metala e like me ke kila kila.Ua lilo ka hana o ka graphite impermeable i lālā koʻikoʻi o ka ʻoihana kalapona.

4、Hoʻohana ʻia ma ke ʻano he mea ʻaʻahu a lubricating

ʻO nā mea kalapona a me nā mea graphite ʻaʻole wale ke kūpaʻa kemika kiʻekiʻe, akā loaʻa pū kekahi mau waiwai lubrication maikaʻi.ʻAʻole hiki ke hoʻomaikaʻi pinepine i ka pale ʻana o nā ʻāpana sliding me ka hoʻohana ʻana i ka ʻaila lubricating ma lalo o nā kūlana kiʻekiʻe, kiʻekiʻe-mehana, a me nā kūlana kiʻekiʻe.Hiki ke hana me ka ʻaila lubricating me ka ʻole o ka ʻaila corrosive ma nā mahana mai -200 a 2000 degere Celsius a me nā wikiwiki hoʻoheheʻe kiʻekiʻe (a hiki i 100 mika/kekona).No laila, nui nā compressors a me nā paila e lawe ana i ka media corrosive e hoʻohana nui i nā apo piston, nā apo hoʻopaʻa, a me nā bearings i hana ʻia i nā mea graphite.ʻAʻole pono lākou i ka hoʻohui ʻana i nā lubricants i ka wā o ka hana.Hana ʻia kēia mea ʻaʻahu me ka hoʻoheheʻe ʻana i ke kalapona maʻamau a i ʻole nā ​​mea graphite me ka resin organik a i ʻole nā ​​mea metala wai.He lubricant maikaʻi nō hoʻi ka emulsion graphite no nā hana metala he nui (e like me ke kaha kiʻi uea a me ke kaha kiʻi paipu).

5、Ma ke ʻano he metallurgical kiʻekiʻe a me nā mea ultrapure

ʻO nā mea hana i hoʻohana ʻia i ka hana ʻana, e like me nā crucibles ulu kristal, nā ipu hoʻomaʻemaʻe kūloko, brackets, fixtures, induction heaters, etc., ua hana ʻia mai nā mea graphite maʻemaʻe kiʻekiʻe.ʻO nā papa insulation graphite a me nā kumu i hoʻohana ʻia i ka hoʻoheheʻe ʻia ʻana, a me nā ʻāpana e like me ke kiʻekiʻe-mehana kūpaʻa ʻana i nā paipu umu ahi, nā koʻokoʻo, nā papa, a me nā grids, ua hana pū ʻia me nā mea graphite.e ʻike hou aku ma www.futmetal.com
