Ka hopena a me ka pono o nā huahana graphite

Ma muli o kona mau waiwai koʻikoʻi he nui, loaʻa i ka graphite nā noi nui ma nā ʻoihana metallurgical, mechanical, electrical, kemikala, textile, a me nā ʻoihana ʻē aʻe. Hana ia ma ke ʻano he mea refractory a mālama i nā ʻano kemika mua o ka flake graphite ʻoiai e hōʻike ana i nā waiwai lubrication ponoʻī ikaika. Hōʻike ʻia ka pauka graphite e ke kūpaʻa waikawa ikaika kiʻekiʻe, ke kūpaʻa corrosion, ke ahonui wela kiʻekiʻe a hiki i ka 3000 ℃ a me ke kūpaʻa wela haʻahaʻa a hiki i ka -204 ℃. Eia kekahi, he ikaika compressive ia e ʻoi aku ana ma mua o 800kg/Cm2 a hōʻike i ke kūpaʻa oxidation me ka pohō kaumaha 1% wale nō ke hōʻike ʻia i ka lewa ma 450 ℃. Eia kekahi, hōʻike ia i ka rebound rate o 15-50% (density 1.1-1.5). No laila, hoʻohana nui ʻia nā huahana graphite i ka metallurgy, ka ʻoihana kemika, ka ʻoihana petrochemical, ka physics ikehu kiʻekiʻe, aerospace, electronics a me nā ʻoihana like ʻole.

He nui nā pono o nā huahana graphite iā lākou iho:

1, loaʻa i nā huahana graphite ka adsorption maikaʻi.

ʻO ke ʻano hakahaka o ke kalapona e hoʻolilo i ke kalapona i mea adsorption maikaʻi, no laila hoʻohana pinepine ʻia ke kalapona ma ke ʻano he mea adsorption no ka omo ʻana i ka wai, ka ʻala, nā mea ʻawahia a pēlā aku. Ua hana mākou i nā hoʻokolohua, i kekahi mau lā i hala aku nei, ua nānā maʻemaʻe loa ka pā bakena graphite i hoʻohana ʻia i ka barbecue, akā e kau i ka hoʻomehana ʻana o ka umu induction, e ʻike ʻoe i ka adsorption barbecue hope loa o ka momona a me nā mea ʻino e puka mālie i waho, akā mai hopohopo, me ka pepa ʻai maʻemaʻe e holoi ai hiki ke hoʻohana ʻia.

2, loaʻa i nā huahana graphite ka conductivity thermal maikaʻi, ka hoʻoili wela wikiwiki, ka wela like, a me ka mālama wahie.

Hoʻomehana koke ʻia nā pepa bakena a me nā pā i hana ʻia me ka graphite, a hoʻomehana like ʻia ka meaʻai i puhi ʻia, moʻa ʻia mai loko mai, a pōkole ka manawa hoʻomehana, ʻaʻole wale ka ʻono i maʻemaʻe, akā hiki ke hoʻopaʻa ʻia nā meaola kumu o ka meaʻai. Ua hana mākou i nā hoʻokolohua, i ka wā e hoʻohana ʻia ai ka pā grill graphite no ka kālua ʻana, ua paʻi ka mea kuke induction i ke ahi i ka hoʻomaka ʻana, a hiki ke hoʻomehana mua ʻia i loko o 20-30 kekona wale nō, a i ka wā e hoʻomaka ai ka meaʻai, hiki ke pāʻani ʻia ma ke ahi liʻiliʻi, hiki ke mālama i ka ikehu.

3, loaʻa i nā huahana graphite ke kūpaʻa kemika a me ke kūpaʻa i ka pala.

He kūpaʻa kemika maikaʻi ko Graphite i ka mahana o ka lumi a ʻaʻole ia e hoʻouka ʻia e kekahi waikawa ikaika, kumu ikaika a me ka mea hoʻoheheʻe organik. No laila, ʻoiai inā hoʻohana lōʻihi ʻia nā huahana graphite, he liʻiliʻi loa ka pohō, inā e holoi ʻia me ka maʻemaʻe e like me ka mea hou.

Loaʻa i nā huahana graphite 4 kahi hopena anti-oxidation a me ka hōʻemi ikaika.

ʻO nā huahana, ʻoi aku ka hoʻomehana ʻana o ka moena graphite, hiki ke hana i nā ion oxygen maikaʻi ʻole, e hoʻoikaika i nā mea a puni, mālama i ke olakino kanaka, pale pono i ka ʻelemakule, a hoʻopiha i ka ʻili me ka luster a me ka elasticity.

5, nā huahana graphite e palekana i ke kaiapuni, ʻaʻohe haumia radioactive, kū'ē i ke kiʻekiʻe o ka mahana.

Hiki i ke kalapona ke lilo i graphite ma hope o ka liʻiliʻi he ʻumikūmālua mau lā a me nā pō o ka graphitization i loko o kahi mahana kiʻekiʻe o 2000-3300 degere, no laila ua lōʻihi ka hoʻokuʻu ʻia ʻana o nā mea ʻawahia a me nā mea ʻino i loko o ka graphite a ua paʻa i loko o ka liʻiliʻi he 2000 degere.

I ka manawa like, ma muli o kona ʻano kūikawā, me ke kūpaʻa wela kiʻekiʻe, ke kūpaʻa haʻalulu wela, ka conductivity uila, ka lubrication, ke kūpaʻa kemika a me ka plasticity a me nā ʻano ʻē aʻe he nui, ua lilo ia i kumuwaiwai hoʻolālā koʻikoʻi i ka hoʻomohala ʻana o ka ʻoihana koa a me kēia au a me nā ʻenehana kiʻekiʻe, hou a ʻoi, nā huahana graphite, e like me nā apo graphite, nā waʻa graphite ua hoʻohana nui ʻia. Ua wānana nā loea honua "ʻo ke kenekulia 20 ke kenekulia o ka silicon, ʻo ke kenekulia 21 ke kenekulia o ke kalapona."

Ma ke ʻano he huahana mineral koʻikoʻi ʻole-metala, e hoʻokō ʻia ka ʻoihana graphite i ka hoʻokele komo. Me ka hoʻokō ʻana o ka ʻōnaehana komo, graphite, nā huahana graphite, e lilo i mea ʻē aʻe ma hope o ka honua laha ʻole, kemika fluorine, a me ka kemika phosphorus, e komo nā ʻoihana alakaʻi i kēia kahua i kahi pae hou o ka hoʻomohala ʻana.
