Nā hiʻohiʻona hoʻohana graphite hiki ke hoʻonui
1. Hoʻohuiʻia ka mea hoʻopaʻa me ka carbon graphite kiʻekiʻe a me ka sulfuric acid concentrated a me ka waikawa nitric no ka mālamaʻana i ka acidification, ka wela wela a laila kaomi a hanaʻia. ʻO ka graphite maʻalahi i hoʻomākaukauʻia he mea hoʻopaʻa hoʻopaʻa kiʻekiʻe hou, a heʻano nanomaterials i ulu ma kahi. aerospace, machinery, electronics, nuclear energy, petrochemical, electric power, shipbuilding, smelting and other industry.
2. ʻO ka graphite hiki ke hoʻonuiʻia i loaʻa i ka hoʻonuiʻana i ka mahana wela ma ke kahua o ka mālamaʻana i ke kaiapuni he waiwai nui ka pore a me ka hana adsorption maikaʻi loa, no laila, he nui ka hoʻohanaʻana i ka mālamaʻana i ke kaiapuni a me ka biomedicine.Ua māheleʻia ka pore o ka graphite hiki ke hoʻonuiʻia iʻeluaʻano: open pore a pani pani. Ka nui pore o expandable graphite mea e pili ana i 98%, a me ka mea nui nui pore me ka nui pore mahele māhele o 1 ~ 10. 3 nm. No ka mea, he macroporous, mesoporous nui, pela a me ka hana kalapona a me na microporous mea i loko o ka adsorption ano okoa. adsorption.1 g expatable graphite hiki adsorb oi aku ma mua o 80 g kaumaha aila, no laila, he olelo hoopomaikai kaiapuni palekana mea no ka hoʻomaʻemaʻe aila pollution ma luna o ka wai surface.In ka wastewater lapaʻau o kemika hui, microorganisms (bacteria) hoʻohana pinepine. ʻO ka graphite hiki ke hoʻonui ʻia he mea lawe microbial maikaʻi, ʻoi aku ka maikaʻi o ka mālama ʻana i ka wai o ka ʻaila pollution macromolecule. Ma muli o kona kūpaʻa kemika maikaʻi a me ka hoʻohana hou ʻana, loaʻa iā ia kahi manaʻo noi maikaʻi.
3, ʻo ka lāʻau lapaʻau ma muli o ka graphite hiki ke hoʻonui ʻia nā hiʻohiʻona adsorption o nā macromolecules organik a me ka biological, he ākea ākea o nā manaʻo noi i nā mea biomedical.
4, kiʻekiʻe ikehu pākaukau mea expanders graphite e like me ka pila mea, o ka hoʻohana 'ana i ka expanders graphite papa pane o ka noa ikehu hoololi i ka uila energy.Usually expandable graphite ua hoʻohana 'ia e like me cathode, lithium like anode, a expandable graphite composite kala oxide e like me cathode, zinc e like me anode. nā pila.
5, pale ahi
Ma muli o ka hoʻonui ʻia o ka graphite hiki ke hoʻonui ʻia a me kona kūpaʻa wela kiʻekiʻe, lilo ka graphite hiki ke hoʻonui ʻia i mea hoʻopaʻa sila maikaʻi loa a hoʻohana nui ʻia i loko o ke ahi sealing strip. He ʻelua mau ʻano nui: ʻo ka mea mua ka hoʻonui ʻana i nā mea graphite a me nā mea hao, inorganic flame retardant, accelerator, vulcanization agent, reinforcing agent, fillerling o nā ʻano like ʻole. Hiki ke hoʻopaʻa i ke kahe o ka uahi mai ka hoʻomaka a hiki i ka hopena ma ka lumi wela a me ke ahi. ʻO ka mea ʻē aʻe ʻo ke aniani fiber band e like me ka mea lawe, ka graphite expansible me ka mea hoʻopaʻa i hoʻopaʻa ʻia ma ka mea lawe. ʻO ke kinoea hoʻoheheʻe anuanu ma ka lumi wela a i ʻole ka wela haʻahaʻa, no laila pono e hoʻohana ʻia me ka sealant wela.
ʻO ka graphite hiki ke hoʻonui i ka lapalapa ahi he mea pale ahi maikaʻi no nā mea plastik. Loaʻa iā ia nā hiʻohiʻona o ka non-toxic a me ka pollution-free. Hiki iā ia ke hoʻokō i ka hopena pale ahi maikaʻi inā hoʻohana wale ʻia a hui pū ʻia me nā mea hoʻopaʻa ahi ʻē aʻe. Hiki i ka graphite hiki ke hoʻokō i ka hopena like ʻole o ka lapalapa ahi, ʻoi aku ka liʻiliʻi ma mua o ka pale ahi maʻamau. Hoʻokaʻaʻike; Hoʻokuʻu ʻia nā radical acid i loko o ka interlayer i ka wā e hoʻonui ai, e hāpai pū ana i ka carbonization o ka substrate, i mea e loaʻa ai nā hopena maikaʻi ma o nā ʻano like ʻole o ke ahi.
ʻeke ʻeke ahi, ʻano ʻano palaki pale ahi, apo pale ahi no ka mea hiki i ka graphite hiki ke hoʻonui ʻia i ke kiʻekiʻe ka hiki ke pale aku i ka pōʻino a he kiʻekiʻe ka hoʻonui nui ʻana, hiki ke hoʻohana ʻia e like me ke ʻeke ahi ahi, ʻano ʻano palaki pale ahi, nā ʻāpana apo pale ahi i ka hoʻonui maikaʻi ʻana i ke ahi retardant mea, i hoʻohana ʻia no ke kūkulu ʻana i ke ahi sealing (e like me: sealing construction pipe, cable, wire, gas, gas pipe, ea paipu).
Hiki ke hoʻohui ʻia nā ʻāpana maikaʻi o ka graphite hiki ke hoʻonui ʻia i nā uhi maʻamau e hana i ka pale ahi maikaʻi a me nā pale anti-static, a hoʻomaikaʻi i ko lākou kūpaʻa wela kiʻekiʻe a me ke kūpaʻa ahi. nā pahu, e hoʻokō i ka hopena pālua o ka pale ahi a me ka uila paʻa.
Ke ahi pale papa, ahi pepa corrosion kū'ē a me ke kiʻekiʻe wela pale: i loko o ka metala kumu laina me expatable graphite papa, expatable graphite papa a me ka metala kumu ma waena o ka carbonized adhesive papa, expatable graphite papa ua uhiia me carbonized pale. ʻAʻole makaʻu ʻo ia i ka hoʻoilo wikiwiki a me ka hoʻomehana wikiwiki, a loaʻa iā ia ka coefficient conduction wela. ʻO ka mahana hana -100 ~ 2 000 ℃. Ka laulā o ka noi, maʻalahi i ka hana, haʻahaʻa kumu kūʻai.
