Nā hiʻohiʻona hoʻohana graphite hiki ke hoʻonui ʻia
1. Hoʻohui ʻia ka mea sila me ka graphite kalapona kiʻekiʻe a me ka waikawa sulfuric i hoʻopaʻa ʻia a me ka waikawa nitric no ka mālama ʻana i ka acidification, ka mālama wela a laila kaomi a hoʻokumu ʻia. ʻO ka graphite palupalu i hoʻomākaukau ʻia he mea sila hana kiʻekiʻe hou, a he ʻano nanomaterials ia i ulu ʻia ma kahi. Ke hoʻohālikelike ʻia me ka rubber asbestos a me nā mea sila kuʻuna ʻē aʻe, loaʻa iā ia ka compressibility maikaʻi, resilience, self-bonding, haʻahaʻa haʻahaʻa a me nā waiwai maikaʻi ʻē aʻe, a hiki ke hoʻohana ʻia i ke kiʻekiʻe wela, ka palaho kiʻekiʻe a me nā kūlana hana ʻino ʻē aʻe no ka manawa lōʻihi. Hoʻohana nui ʻia nā papa graphite a me nā ʻāpana sila i hana ʻia e ia ma ka aerospace, mīkini, electronics, ikehu nukelea, petrochemical, mana uila, kūkulu moku, hoʻoheheʻe a me nā ʻoihana ʻē aʻe. No ka mea he māmā kona kaumaha, conductive, thermal conductivity, ke kū'ē ʻana i ka mahana kiʻekiʻe, ke kū'ē ʻana i ka waikawa a me ka alkali corrosion, ke kūpaʻa maikaʻi, lubrication, plasticity a me ke kūpaʻa kemika a me nā waiwai maikaʻi ʻē aʻe, i ʻike ʻia ʻo "mōʻī o ka sila" o ka honua.
2. ʻO ka graphite hiki ke hoʻonui ʻia i loaʻa ma o ka hoʻonui ʻana i ka mahana kiʻekiʻe ma ke kahua o ka palekana kaiapuni he ʻano pore waiwai a me ka hana adsorption maikaʻi loa, no laila he ākea ka hoʻohana ʻana i ka palekana kaiapuni a me ka biomedicine. Ua māhele ʻia ke ʻano pore o ka graphite hiki ke hoʻonui ʻia i ʻelua ʻano: ka pore hāmama a me ka pore pani. ʻO ka nui o ka pore o ka graphite hiki ke hoʻonui ʻia ma kahi o 98%, a ʻo ia ka pore nui me ka laulā hoʻolaha nui o ka pore o 1 ~ 10.3 nm. No ka mea he macroporous, mesoporous nui, no laila a me ke kalapona i hoʻāla ʻia a me nā mea microporous ʻē aʻe i nā ʻano adsorption he ʻokoʻa. He kūpono ia no ka adsorption pae wai, akā ʻaʻole no ka adsorption pae kinoea. He oleophilic a hydrophobic i ka adsorption pae wai. Hiki i ka 1 g graphite hiki ke adsorb ma mua o 80 g ʻaila kaumaha, no laila he mea hoʻohiki ia no ka hoʻomaʻemaʻe ʻana i ka haumia aila ma ka ʻili wai. I ka mālama ʻana i ka wai ʻino o nā ʻoihana kemika, hoʻohana pinepine ʻia nā microorganism (bacteria). He mea lawe microbial maikaʻi ka graphite hiki ke hoʻonui ʻia, ʻoi aku hoʻi i ka mālama ʻana i ka wai o ka haumia macromolecule organik aila. Ma muli o kona kūpaʻa kemika maikaʻi a me ka hoʻohana hou ʻana i ka wā hou, he manaʻolana maikaʻi kona no ka hoʻohana ʻana.
3, ma muli o ka graphite hiki ke hoʻonui ʻia, loaʻa i ka lāʻau lapaʻau nā ʻano adsorption o nā macromolecules organik a me ke olaola, a he ākea ka laulā o nā manaʻolana noi i nā mea biomedical.
4, ʻo ka mea hoʻonui ikehu kiʻekiʻe o ka pila uila he graphite e like me ka mea pila, ʻo ia ka hoʻohana ʻana i ka hoʻololi ʻana o ka ikehu manuahi i ka ikehu uila i ka pane ʻana o ka papa graphite expanders. Hoʻohana pinepine ʻia ka graphite expanded e like me ka cathode, lithium e like me ka anode, a i ʻole ka graphite expanded composite silver oxide e like me ka cathode, zinc e like me ka anode. Ua hoʻohana ʻia ka ʻīnika fluoride Fossil, ka waikawa graphite a me ka graphite expanded o nā halides metala e like me AuCl3 a me TiF4 i nā pila.
5, pale ahi
Ma muli o ka hiki ke hoʻonui ʻia o ka graphite hiki ke hoʻonui ʻia a me kona kūpaʻa wela kiʻekiʻe, lilo ka graphite hiki ke hoʻonui ʻia i mea sila maikaʻi loa a hoʻohana nui ʻia i loko o ke kaha sila ahi. ʻElua ʻano nui: ʻo ka mua ka hoʻonui ʻia ʻana o nā mea graphite a me nā mea laholio, inorganic flame retardant, accelerator, vulcanization agent, reinforcement agent, filler mixing, vulcanization, molding, i hana ʻia me nā kikoʻī like ʻole o ka hoʻonui ʻana i ka hoʻonui ʻana i ka rubber strip, i hoʻohana nui ʻia no nā puka ahi, nā puka makani ahi a me nā manawa ʻē aʻe. Hiki i ka hoʻonui ʻana i ka hoʻonui ʻana ke ālai i ke kahe o ka uahi mai ka hoʻomaka a hiki i ka hopena ma ka mahana o ka lumi a me ke ahi. ʻO kekahi ʻo ke kāʻei fiber aniani e like me ka mea lawe, ʻo ka graphite hiki ke hoʻonui ʻia me kahi mea hoʻopaʻa i hoʻopaʻa ʻia ma ka mea lawe, ʻo ka mea hoʻopili i hana ʻia ma ka mahana kiʻekiʻe o ka mea carbonized i hāʻawi ʻia e ka ikaika shear hiki ke pale pono i ka paheʻe graphite. Hoʻohana nui ʻia no nā puka ahi, akā ʻaʻole hiki ke ālai pono i ke kahe o ke kinoea flue anu ma ka mahana o ka lumi a i ʻole ka mahana haʻahaʻa, no laila pono e hoʻohana ʻia me ka sealant mahana o ka lumi.
ʻO ka graphite expandable flame retardant he mea pale ahi maikaʻi no nā mea plastik. Loaʻa iā ia nā ʻano o ka ʻawaʻawa ʻole a me ka haumia ʻole. Hiki iā ia ke hoʻokō i ka hopena pale ahi kūpono ke hoʻohana wale ʻia a i ʻole i hui pū ʻia me nā mea pale ahi ʻē aʻe. Hiki i ka graphite expansable ke hoʻokō i ka hopena pale ahi like, ʻoi aku ka liʻiliʻi o ka nui ma mua o ka mea pale ahi maʻamau. ʻO kona kumumanaʻo hana: i ke kiʻekiʻe wela, hiki i ka hoʻonui ʻana o ka graphite ke hoʻonui koke, e hoʻopau ana i ka lapalapa, a ʻo ka mea hoʻonui graphite i hana ʻia e ia ua uhi ʻia ma luna o ka ʻili o ka substrate, i hoʻokaʻawale ʻia mai ka radiation thermal a me ka hoʻopili ʻana o ka oxygen; Hoʻokuʻu ʻia nā radical acid i loko o ka interlayer i ka wā hoʻonui, kahi e paipai pū ai i ka carbonization o ka substrate, i mea e loaʻa ai nā hopena maikaʻi ma o nā ʻano hana pale ahi like ʻole.
ʻEke pale ahi, mea poloka pale ahi ʻano plastik, apo pale ahi no ka mea ʻo ka graphite expandable i ka mahana kiʻekiʻe he hiki ke pale aku i ka pōʻino a he wikiwiki ka hoʻonui ʻana, hiki ke hoʻohana ʻia e like me ka ʻeke pale ahi, mea poloka pale ahi ʻano plastik, nā ʻāpana apo pale ahi i loko o ka mea pale lapalapa hoʻonui kūpono, hoʻohana ʻia no ke sila ʻana i ke ahi o ke kūkulu ʻana (e like me: ke sila ʻana i ka paipu kūkulu, uwea, uea, kinoea, paipu kinoea, paipu ea ma o ka lua a me nā manawa ʻē aʻe).
Hoʻohana ʻia i nā uhi Hiki ke hoʻohui ʻia nā ʻāpana maikaʻi o ka graphite hiki ke hoʻonui ʻia i nā uhi maʻamau e hana i nā uhi lapalapa maikaʻi a me nā uhi anti-static, a hoʻomaikaʻi i ko lākou kūpaʻa wela kiʻekiʻe a me ke kūʻē ʻana i ke ahi. ʻO ka nui o ka papa kalapona māmā ʻaʻole hiki ke kuni i hana ʻia i ke ahi hiki ke pale pono i ka radiation wela i ka substrate a pale pono i ka substrate. Eia kekahi, no ka mea he alakaʻi uila maikaʻi ka graphite, hiki i ka uhi ke pale i ka hōʻiliʻili ʻana o ka uku electrostatic, i hoʻohana ʻia no nā pahu mālama petroleum, e hoʻokō i ka hopena pālua o ka pale ʻana i ke ahi a me ka uila static.
Papa pale ahi, pepa ahi e kū'ē i ka palaho a me ka papa pale wela kiʻekiʻe: ma ke kumu metala i hoʻopaʻa ʻia me ka papa graphite expatable, ka papa graphite expatable a me ke kumu metala ma waena o ka papa hoʻopili carbonized, ua uhi ʻia ka papa graphite expatable me ka papa pale carbonized. Ke kū'ē i ka palaho, ke kū'ē i ke kiʻekiʻe o ke ana wela a me ke kaomi kiʻekiʻe. I ka manawa like, hiki ke hoʻohana maʻamau ʻia i ka mahana haʻahaʻa. ʻAʻole makaʻu i ka hoʻoluʻolu wikiwiki a me ka hoʻomehana wikiwiki, a he coefficient conduction wela maikaʻi loa. ʻO ka mahana hana he -100 ~ 2 000 ℃. ʻO ka laulā o ka noi, maʻalahi ke hana, haʻahaʻa ke kumukūʻai. Eia kekahi, hoʻonui ʻia ka graphite expatable i ka mahana kiʻekiʻe, ka pepa graphite i paʻi ʻia, hoʻohana ʻia hoʻi i nā wahi insulation ahi.
