ʻO ke kaʻina hana hoʻomākaukau o ka graphite wela ka mea e wela ai i nā ʻāpana graphite a i ʻole nā ʻāpana graphite i ka wela kiʻekiʻe, a laila e hoʻokomo iā lākou i loko o nā mea nui me kahi kikoʻī. Nui nā ala e hoʻomākaukau ai i ka graphite wela, me ka isothermal hot-pressing, non-isothermal hot-pressing, wikiwiki wikiwiki, plasma hot-pressing, etc.
ʻO nā huahana o ka graphite wela i loko o nāʻano likeʻole,ʻo ka nui o ka pā, ka poloka, ka pepa, ka'ōpala, ka pauka, a me nā mea'ē aʻe. , nā kapuahi hau, aerospace, kiʻekiʻe-mehana structural ʻāpana, chemical reactors a me nā māla ʻē aʻe.
Loaʻa i ka graphite wela nā waiwai maikaʻi:
ʻO ka conductivity maikaʻi: ʻoi aku ka maikaʻi o ka graphite wela, ʻoi aku ma mua o 10 mau manawa o ka graphite maʻamau, no laila ua hoʻohana nui ʻia e like me nā mea electrode.
ʻOi aku ka maikaʻi o ka thermal conductivity: ʻoi aku ka maikaʻi o ka graphite wela, a hiki i ka conductivity thermal ke piʻi aku ma mua o 2000W / m • K. No laila, hoʻohana nui ʻia ka graphite wela i nā mea hoʻomehana uila, nā umu ahi, nā mea hoʻololi wela wela a me nā mea ʻē aʻe. nā mahinaʻai.
Paʻa kemika maikaʻi: paʻa maikaʻi ka graphite i hoʻopaʻa ʻia i ka wela ma lalo o ke kiʻekiʻe kiʻekiʻe a me ka pōʻino kemika, a ʻaʻole hiki ke hoʻopili i ka corrosion a me ka oxidation.
ʻO nā waiwai mechanical maikaʻi loa: ʻo ka graphite wela wela he mea ikaika kiʻekiʻe me ka hoʻopiʻi maikaʻi ʻana, ke kuʻi ʻana a me ka pale ʻana.
ʻO ka hana hoʻoponopono maikaʻi: ʻo ka graphite wela wela ka hana hoʻoponopono maikaʻi loa, a hiki ke ʻoki ʻia, wili, huli, wili a me nā kaʻina ʻoki ʻē aʻe e like me nā pono like ʻole.
Ma kahi huaʻōlelo, ʻo ka graphite wela kahi ʻano mea graphite maʻemaʻe kiʻekiʻe me ka hana maikaʻi loa a loaʻa kahi manaʻo noi ākea. ʻAʻole hiki iā ia ke hoʻokō wale i nā pono o nā māla like ʻole, akā hoʻonohonoho pū i ka hana e like me nā pono o nā mea kūʻai aku e hoʻokō i nā koi noi like ʻole.
