Ipu hoʻoheheʻe Graphite
Hoʻohana kūikawā ʻia kēia ʻano graphite ipu hao no ka hana ʻoniʻoni i uhi ʻia i ke kiʻi ʻoniʻoni ma lalo o ke ʻano holo. ʻO ka maikaʻi o ka ipu hoʻoheheʻe graphite e hoʻopili nui i ka maikaʻi o ke kiʻi a me ke kumukūʻai hana. ʻO ka vaporum evaporation aluminika uhi kahi hana ma lalo o ke ʻano o ka hakahaka e hoʻopili i ka alumini ma luna o nā substrates kiʻi e hana i kahi kiʻi ʻoniʻoni. E like me nā substrates e like me BOPET, BONY, BOPP, PE, PVC, ke hoʻololi ʻana i ka evaporation pololei i ke kaʻina hana maʻamau. ʻO ke kaʻina hana evaporation aluminium uhi e koi ai i ka ipu hao grafite kiʻekiʻe, a hiki iā mākou ke kūpaʻa a me ka maikaʻi e hāʻawi.

ʻIke ʻia ka Graphite
Hoʻokaʻawale ʻia ʻo Graphite i loko o ka manaʻo graphite i hoʻokumu ʻia, ʻike ʻia ka graphite polyacrylonitrile (PAN), a me ka graphite i hoʻokumu ʻia ma ka viscose ma muli o ke ʻano like ʻole o nā felts kumu. ʻO ke kumu nui e hoʻohana ʻia e like me ka mālama ʻana i ka wela a me nā mea hoʻāno wela no nā kapuahi hoʻoheheʻe silicon monocrystalline. I ka ʻenehana kemika, hiki ke hoʻohana ʻia ma ke ʻano he kānana no nā reagents kemikala corrosive kūpikipiki kiʻekiʻe.
ʻIke ʻia ʻo Carbon ka graphite ma hope o ka mālama ʻia ʻana i kahi mahana wela ma luna o 2000 ℃ ma lalo o ka hawewe a i ʻole lewa inert. ʻOi aku ke kiʻekiʻe o ke kalapona ma mua o ko ke kalapona i manaʻo ʻia, e piʻi ana ma mua o 99%. I ka hopena o nā makahiki 1960, ua loaʻa ka graphite i ka honua. Hoʻokaʻawale ʻia ʻo Graphite i loko o ka pitch-based, polyacrylonitrile-based graphite i manaʻo a me ka viscose-based graphite i manaʻo ʻia ma muli o ke ʻano ʻokoʻa o ka manaʻo mua.
