Ka hoʻohana ʻana i ka Graphite

1. Ma ke ʻano he mea pale: Loaʻa i ka Graphite a me kāna huahana nā waiwai o ke kūpaʻa wela kiʻekiʻe a me ka ikaika kiʻekiʻe. Hoʻohana nui ʻia lākou i ka ʻoihana metallurgical e hana i nā ipu hoʻoheheʻe graphite. I ka hana kila, hoʻohana pinepine ʻia ka graphite ma ke ʻano he mea pale no nā ingots kila a me ka liner o loko o nā umu metallurgical.

2. Mea alakaʻi: hoʻohana ʻia i ka ʻoihana uila ma ke ʻano he electrode maikaʻi no ka hana ʻana i nā electrodes, nā pulumu, nā koʻokoʻo kalapona, nā paipu kalapona, nā mea kahe maikaʻi mercury, nā gaskets graphite, nā ʻāpana kelepona, nā uhi no nā paipu kiʻi kīwī, a pēlā aku.

3. Nā mea hoʻoluʻu pale ʻaʻahu: Hoʻohana pinepine ʻia ka graphite ma ke ʻano he mea hoʻoluʻu i ka ʻoihana mīkini. ʻAʻole hoʻohana pinepine ʻia nā aila hoʻoluʻu ma lalo o ka wikiwiki kiʻekiʻe, ke ana wela kiʻekiʻe a me ke kaomi kiʻekiʻe, ʻoiai hiki i nā mea pale ʻaʻahu graphite ke hana i nā wikiwiki paheʻe kiʻekiʻe o 200 ~ 2000 °C me ka ʻole o ka aila hoʻoluʻu. Hoʻohana nui ʻia nā lako he nui e lawe ana i nā mea ʻino i nā mea graphite e hana i nā kīʻaha piston, nā sila a me nā bearings. ʻAʻole pono lākou e hoʻoluʻu ʻia i ka wā o ka hana.

4. Loaʻa i ka Graphite ke kūpaʻa kemika maikaʻi. ʻO ka graphite i hana kūikawā ʻia, nona nā ʻano o ke kūpaʻa ʻana i ka pala, ka conductivity thermal maikaʻi a me ka permeability haʻahaʻa, hoʻohana nui ʻia i ka hana ʻana o nā mea hoʻololi wela, nā pahu hana, nā condensers, nā hale kiaʻi kuni, nā hale kiaʻi absorption, nā mea hoʻoluʻolu, nā mea hoʻomehana, nā kānana. , nā lako pamu. Hoʻohana nui ʻia i ka petrochemical, hydrometallurgy, ka hana waikawa a me ka alkali, ka fiber synthetic, ka pepa a me nā ʻoihana ʻē aʻe, hiki ke mālama i ka nui o nā mea metala.

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

6, no ka ʻoihana ikehu atomika a me ka ʻoihana pale kaua aupuni: loaʻa i ka graphite kahi moderator neutron maikaʻi no ka hoʻohana ʻana i nā reactors atomika, ʻo ka uranium-graphite reactor kahi reactor atomika i hoʻohana nui ʻia. Pono ka mea hoʻēmi i ka wikiwiki i loko o ka reactor nukelea ma ke ʻano he kumu mana e loaʻa kahi kiko heheʻe kiʻekiʻe, paʻa, a me nā waiwai pale i ka palaho, a hiki i ka graphite ke hoʻokō piha i nā koi i luna. He kiʻekiʻe loa ka maʻemaʻe o ka graphite i hoʻohana ʻia ma ke ʻano he reactor atomika, a ʻaʻole pono e ʻoi aku ka nui o ka haumia ma mua o nā ʻumi o PPM. Ma ke ʻano kūikawā, pono e emi ka nui o ka boron ma mua o 0.5 PPM. I ka ʻoihana pale kaua, hoʻohana ʻia ka graphite e hana i nā nozzles rocket wahie paʻa, nā cones ihu missile, nā ʻāpana o nā lako hoʻokele lewa, nā mea insulation a me nā mea pale radiation.

7. Pale pū ka graphite i ka haumia ʻana o ka paila. ʻO ka hoʻohui ʻana i kahi nui o ka pauka graphite i ka wai (ma kahi o 4 a 5 grams no kēlā me kēia tona o ka wai) e pale ai i ka haumia ʻana ma luna o ka ʻili paila. Eia kekahi, hiki ke uhi ʻia ka graphite ma nā ʻōpuʻu hao, nā kaupaku, nā alahaka a me nā paipu e pale aku i ka pala a me ka ʻōpala.
8. Hiki ke hoʻohana ʻia ke graphite ma ke ʻano he penikala alakaʻi, pigment, a me ka mea hoʻopili. Ma hope o ka hana kūikawā ʻana o ka graphite, hiki ke hana ʻia nā mea kūikawā like ʻole no nā ʻāpana ʻoihana pili.
9. Electrode: Hiki i ke Graphite ke pani i ke keleawe ma ke ʻano he electrode. I nā 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%. 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 i mana nui ʻia ma mua, 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.
