Ka hopena a me ka pono waiwai o nā huahana graphite

Ma muli o kāna mau waiwai koʻikoʻi, ʻike ka graphite i nā noi nui i ka metallurgical, mechanical, uila, kemika, textile, a me nā ʻoihana ʻoihana ʻē aʻe. Hoʻohana 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 lubricating ponoʻī. Hōʻike ʻia ka pauka Graphite e ka ikaika kiʻekiʻe o ka acid resistance, corrosion resistance, kiʻekiʻe wela hoʻomanawanui a hiki i 3000 ℃ a me ka haʻahaʻa haʻahaʻa haʻahaʻa a hiki i -204 ℃. Hoʻohui ʻia, hoʻokiʻekiʻe ʻo ia i ka ikaika compressive ma mua o 800kg/Cm2 a hōʻike i ke kūpaʻa oxidation me ka 1% pohō kaumaha wale nō ke ʻike ʻia i ka ea 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, ʻoihana kemika, ʻoihana petrochemical, kiʻekiʻe ikehu physics, aerospace, electronics a me nā ʻano hana ʻē aʻe.

Loaʻa i nā huahana graphite nā pono nui loa:

1, loaʻa nā huahana graphite i ka adsorption maikaʻi.

ʻO ka hana ʻole o ke kalapona e loaʻa i ke kalapona ka adsorption maikaʻi, no laila hoʻohana pinepine ʻia ke kalapona ma ke ʻano he adsorption mea no ka hoʻomoʻa ʻana i ka wai, ʻala, nā mea ʻawaʻawa a pēlā aku. Ua hana mākou i nā hoʻokolohua, i kekahi mau lā i hala aku nei ka barbecue hoʻohana i ka graphite baking tray e nānā maʻemaʻe loa, akā e kau i ka umu induction hoʻomehana, e ʻike ʻoe i ka adsorption barbecue hope loa o ka momona a me nā mea ʻino e lohi lohi, akā mai hopohopo, me kahi hiki ke hoʻohana ʻia ka pepa ʻai maʻemaʻe e holoi maʻemaʻe.

2, huahana graphite maikaʻi thermal conductivity, hoʻokēʻai wela hoʻoili, ʻaʻahu wela, wahie hoola.

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

3, loaʻa i nā huahana graphite ke kūpaʻa kemika a me ka pale ʻana i ka corrosion.

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

Loaʻa nā huahana graphite 4 i ka hopena anti-oxidation a me ka ho'ēmi.

Hiki i nā huahana, ʻoi aku ka graphite matress wela ke hana i nā ion oxygen maikaʻi ʻole, hoʻoikaika i nā mea a puni, mālama i ke olakino kanaka, pale pono i ka ʻelemakule, hoʻopiha i ka ʻili i ka luster a me ka elasticity.

5, nā huahana graphite ke olakino kaiapuni, ʻaʻohe pollution radioactive, kūpaʻa wela kiʻekiʻe.

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

I ka manawa like, ʻo nā huahana graphite ma muli o kona ʻano kūikawā, me ke kūpaʻa kiʻekiʻe o ka wela, ke kūpaʻa ʻana o ka wela, ka conductivity uila, ka lubrication, ke kūpaʻa kemika a me ka plasticity a me nā ʻano ʻē aʻe he nui i kumu waiwai nui i ka hoʻomohala ʻana i ka ʻoihana koa a me ka ʻoihana hou. a me ka ʻenehana kiʻekiʻe, hou a me ka ʻoi, nā huahana graphite, e like me nā apo graphite, hoʻohana nui ʻia nā waʻa graphite. Ua wānana ka poʻe akamai o ka honua "ʻo ke kenekulia 20 ke kenekulia o ke silikoni, ʻo ka 21st century ke kenekulia o ke kalapona."

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