Ka hoʻohana ʻana i ka graphite

1. E like me refractory mea: Graphite a me kāna mau huahana i nā waiwai o ke kiʻekiʻe wela kū'ē a me ka ikaika kiʻekiʻe. Hoʻohana nui ʻia lākou i ka ʻoihana metallurgical e hana i nā crucibles graphite. I ka hana kila, hoʻohana maʻamau ʻia ka graphite ma ke ʻano he mea pale no nā mea kila a me ka liner i loko o nā kapuahi metallurgical.

2. Conductive mea: hoʻohana 'ia i loko o ka uila 'oihana e like me ka maikai electrode no ka hana 'ana o electrodes, brushes, kalapona kookoo, kalapona paipu, mercury maikaʻi kahe kahe, graphite gaskets, kelepona'āpana, uhi no ke kīwī kiʻi paipu, etc.

3. ʻO nā lubricants pale lole: Hoʻohana pinepine ʻia ʻo Graphite ma ke ʻano he lubricant i ka ʻoihana mīkini. ʻAʻole hoʻohana pinepine ʻia nā aila lubricating ma lalo o ka wikiwiki kiʻekiʻe, ke kiʻekiʻe kiʻekiʻe a me nā kūlana kiʻekiʻe, ʻoiai ʻo ka graphite e hoʻohana i nā mea kūʻokoʻa hiki ke hana i nā wikiwiki sliding kiʻekiʻe o 200 ~ 2000 ° C me ka ʻole o ka aila lubricating. Hoʻohana nui ʻia nā mea hana e lawe ana i ka media corrosive i nā mea graphite e hana i nā kīʻaha piston, sila a me nā bearings. ʻAʻole pono lākou e lubricated i ka wā o ka hana.

4. He paʻa kemika maikaʻi ka graphite. Hoʻohana nui ʻia ka graphite i hoʻomaʻamaʻa kūikawā, nona nā ʻano o ka corrosion resistance, maikaʻi thermal conductivity a me ka haʻahaʻa haʻahaʻa, i ka hana ʻana i nā mea hoʻololi wela, nā pahu hopena, nā condensers, nā hale kiaʻi puhi, absorption towers, coolers, heaters, filters. , lako pahū. Hoʻohana nui ʻia i ka petrochemical, hydrometallurgy, acid and alkali production, synthetic fiber, pepa a me nā ʻāpana ʻoihana ʻē aʻe, hiki ke mālama i ka nui o nā mea metala.

5. No ka hoʻolei ʻana, ke one, ka hoʻoheheʻe ʻana a me nā mea pyrometallurgical: No ka mea he liʻiliʻi liʻiliʻi ka hoʻonui wela o ka graphite a hiki ke kū i ka hoʻoilo wikiwiki a me nā loli wikiwiki, hiki ke hoʻohana ʻia e like me ka mold no nā aniani. Ma hope o ka hoʻohana ʻana i ka graphite, hiki ke hoʻohana ʻia ka metala ferrous no ka loaʻa ʻana o nā ana hoʻolei pololei a me ka hoʻopau ʻana o ka ʻili kiʻekiʻe. Hiki ke hoʻohana ʻia me ka ʻole o ka hana ʻana a i ʻole ka hana liʻiliʻi, pēlā e mālama ai i ka nui o ka metala.

6, no ka ʻoihana ikehu atomic a me ka ʻoihana pale aupuni: he mea hoʻoponopono neutron maikaʻi ka graphite no ka hoʻohana ʻana i nā reactors atomic, ʻo ka uranium-graphite reactor he mea hoʻohana nui loa. ʻO ka mea decelerating i loko o ka nukili reactor ma ke ʻano he kumu mana e loaʻa kahi kiʻekiʻe heheʻe, paʻa, a me nā waiwai corrosion-kūpono, a hiki i ka graphite ke hoʻokō pono i nā koi i luna. ʻO ka maʻemaʻe o ka graphite i hoʻohana ʻia ma ke ʻano he atomic reactor he kiʻekiʻe loa, a ʻaʻole pono ka maʻemaʻe o ka haumia ma mua o ʻumi o PPM. ʻO ka mea nui, pono ka liʻiliʻi o ka boron ma mua o 0.5 PPM. I ka ʻoihana pale, hoʻohana pū ʻia ka graphite e hana i nā nozzles rocket wahie paʻa, missile nose cones, nā ʻāpana o nā lako hoʻokele lewa, nā mea insulation a me nā mea pale radiation.

7. ʻAʻole hoʻi ka graphite i ka hewa ʻana o ka paila. ʻO ka hoʻohui ʻana i kahi nui o ka pauda graphite i ka wai (ma kahi o 4 a 5 mau kalama o ka wai) e pale ai i ka ʻinoʻino ma ka ʻili o ka paila. Eia kekahi, hiki ke uhi ʻia ka graphite ma nā kapuahi metala, nā kaupaku, nā alahaka a me nā paipu e pale ai i ka pala a me ka ʻōpala.
8. Hiki ke hoʻohana ʻia ka graphite e like me ke alakaʻi penikala, ka puaʻa, a me ka mea hoʻonani. Ma hope o ka hana kūikawā o ka graphite, hiki ke hana ʻia nā mea kūikawā like ʻole no nā ʻāpana ʻoihana kūpono.
9. Electrode: Hiki i ka graphite ke pani i ke keleawe ma ke ʻano he electrode. I ka makahiki 1960, ua hoʻohana nui ʻia ke keleawe ma ke ʻano he mea electrode, me ka nui o ka hoʻohana ʻana ma kahi o 90% a me ka graphite ma kahi o 10% wale nō. I ke kenekulia 21, ua hoʻomaka ka nui o nā mea hoʻohana e koho i ka graphite ma ke ʻano he mea electrode, ma ʻEulopa, ʻoi aku ma mua o 90%. ʻO ka mea electrode ma luna nei he graphite. ʻO ke keleawe, ka mea electrode mana nui, ua aneane nalowale kona mau pono i hoʻohālikelike ʻia me nā electrodes graphite. Hoʻololi mālie ʻo Graphite i ke keleawe ma ke ʻano he mea koho no nā electrodes EDM.
