ʻO ka graphite synthetic he polycrystalline e like me ka crystallography. Nui nā ʻano graphite artificial a me nā kaʻina hana like ʻole.
Ma ka manaʻo ākea, ʻo nā mea graphite āpau i loaʻa ma hope o ka carbonization o nā mea organik a me ka graphitization i ke kiʻekiʻe wela hiki ke hui pū ʻia e like me ka graphite artificial, e like me carbon (graphite) fiber, pyrolytic carbon (graphite), foam graphite, etc.
Ma ke ʻano haiki, ʻike pinepine ʻia ka graphite artificial i nā mea paʻa nui, e like me ka graphite electrode, isostatic graphite, i hana ʻia e ka hui ʻana, ka hui ʻana, ka hoʻoheheʻe ʻana, ka carbonization (i ʻike ʻia ʻo ka ʻai ʻana i ka ʻoihana) a me ka graphitization, me ka haʻahaʻa haʻahaʻa haumia o ka lanahu maka. (petroleum coke, asphalt coke, etc.) as aggregate, coal pitch as binder.
Nui nā ʻano o ka graphite artificial, ʻo ia hoʻi ka pauka, ka fiber a me ka poloka, ʻoiai ʻo ke ʻano haiki o ka graphite artificial ka mea maʻamau, pono e hana ʻia i kekahi ʻano ke hoʻohana ʻia. Hiki ke noʻonoʻo ʻia he ʻano mea multiphase, me ka graphite phase i hoʻololi ʻia e nā ʻāpana kalapona e like me ka petroleum coke a i ʻole asphalt coke, ka graphite phase i hoʻololi ʻia e ka lanahu pitch binder i uhi ʻia a puni nā ʻāpana, ka hōʻiliʻili ʻana a i ʻole nā pores i hana ʻia e ka lanahu. pitch binder ma hope o ka hoʻomaʻamaʻa wela, etc. ʻO ka mea maʻamau, ʻoi aku ka kiʻekiʻe o ka mahana mālama wela, ʻoi aku ka kiʻekiʻe o ke kiʻekiʻe o ka graphitization. ʻO ka hana ʻoihana o ka graphite artificial, ʻoi aku ka liʻiliʻi o ka graphitization ma mua o 90%.
Ke hoʻohālikelike ʻia me ka graphite maoli, ʻoi aku ka maikaʻi o ka graphite artificial i ka wela wela a me ka conductivity uila, lubricity a me ka plasticity, akā ʻoi aku ka maikaʻi o ka graphite artificial, ke kūpaʻa corrosion a me ka haʻahaʻa permeability ma mua o ka graphite maoli.
ʻO nā mea maka no ka hana ʻana i ka graphite artificial ka nui o ka petroleum coke, needle coke, asphalt coke, coal pitch, carbon microspheres, etc. ʻO kāna huahana downstream ka nui o ka graphite electrode, pre-baked anode, isostatic graphite, high clean graphite, nuclear graphite, wela. mea hoʻololi a pēlā aku.
Hōʻike nui ʻia ka noi huahana o ka graphite artificial i nā ʻano aʻe:
1. Graphite electrode: Me ka petroleum coke a me ka nila coke e like me nā mea maka a me ka lanahu pitch e like me ka binder, ka graphite electrode i hana ʻia e ka calcination, batching, mixing, pressing, roasting, graptitization and machining. Hoʻohana nui ʻia ia i ke kila kapuahi uila, silika ʻoihana, phosphorus melemele a me nā mea hana ʻē aʻe ma o ka hoʻokuʻu ʻana i ka ikehu uila ma ke ʻano o ka arc e wela a hoʻoheheʻe i ka uku.
2. Pre-baked anode: hana ʻia me ka petroleum coke e like me ka mea maka a me ka lanahu pitch e like me ka binder ma o ka calcination, batching, mixing, pressing, roasting, impregnation, graphitization and machining, hoʻohana maʻamau ia e like me conductive anode o nā lako alumini electrolytic.
3. ʻO ka lawe ʻana, ke apo sealing: lawe i nā lako media corrosive, hoʻohana nui ʻia ka graphite artificial i hana ʻia me nā apo piston, nā apo hoʻopaʻa a me nā bearings, hana me ka ʻole o ka hoʻohui ʻana i ka aila lubricating.
4. Heat exchanger, kānana papa: artificial graphite i nā hiʻohiʻona o ka corrosion kū'ē, maikaʻi thermal conductivity a me ka haʻahaʻa permeability. Hoʻohana nui ʻia ia i ka ʻoihana kemika e hana i ka hoʻololi wela, ka tank reaction, absorber, kānana a me nā mea hana ʻē aʻe.
5. Special graphite: with high quality petroleum coke as raw material, coal pitch or synthetic resin as binder, through raw material preparation, batching, kneading, pressing, crushing, mixing kneading, molding, multiple roasting, multiple penetration, purification and graphitization, machining a hana ʻia, maʻamau me ka graphite isostatic, graphite nuklea, graphite maʻemaʻe kiʻekiʻe, hoʻohana ʻia i ka aerospace, electronics, nā ʻoihana nuklea.
