Inowedzera graphite kushandiswa kwezviitiko
1. Iyo yekuisa chisimbiso inosanganiswa nepamusoro kabhoni graphite uye concentrated sulfuric acid uye nitric acid ye acidification kurapwa, kupisa kupisa uye ipapo kudzvanywa uye kuumbwa. Iyo inochinjika graphite yakagadzirirwa chinhu chitsva chepamusoro-chisimbiso chekuisa chisimbiso, uye imhando yemananomaterials akakura mu situ.Kuenzaniswa neasbestos rubber uye zvimwe zvechisimbiso zvinhu zvechisimbiso, ine yakanaka compressibility, resilience, self-bonding, low density uye zvimwe zvinhu zvakanakisa, uye inogona kushandiswa mukupisa kwepamusoro, kuora kwepamusoro uye mamwe maplateti akareba akaitwa neakaomesesa mamiriro ekushanda uye mamwe maplate akareba anogadzirwa neakaomesesa mamiriro ekushanda ayo. Inoshandiswa zvakanyanya mumhepo, michina, zvemagetsi, simba renyukireya, petrochemical, simba remagetsi, shipbuilding, smelting uye mamwe maindasitiri.Nekuti ine uremu huremu, conductive, thermal conductivity, kupisa kwekushisa kwepamusoro, acid uye alkali corrosion resistance, resilience, lubrication, plasticity uye kugadzikana kwemakemikari nezvimwe zvinhu zvakanakisisa zvepasi rose, inozivikanwa se "senyika".
2. Girafu inowedzerwa inowanikwa nekuwedzera kwekushisa kwepamusoro mumunda wekuchengetedzwa kwezvakatipoteredza ine hupfumi hwepore chimiro uye yakanakisa adsorption performance, saka ine huwandu hwakawanda hwekushandisa mukuchengetedzwa kwezvakatipoteredza uye biomedicine.Iyo pore chimiro chekuwedzera graphite inokamurwa kuva marudzi maviri: yakazaruka pore uye yakavharwa pore. Iyo pore vhoriyamu yekuwedzera graphite inosvika 98%, uye inonyanya hombe pore ine pore saizi yekuparadzira siyana ye1 ~ 10. 3 nm.Nekuti iyo macroporous, mesoporous kunyanya, saka uye activated kabhoni uye mamwe ma microporous zvinhu mu adsorption maitiro akasiyana.Inokodzera liquid phase adsorption uye kwete gasi adsorption. hydrophobic in liquid phase adsorption.1 g expatable graphite can adsorb more than 80 g heavy oil, saka ivimbiso yekuchengetedzwa kwezvakatipoteredza zvinhu zvekuchenesa kusvibiswa kwemafuta pamusoro pemvura.Mukutsvaira kwemvura yemakemikari emakemikari, microorganisms (bhakitiriya) inowanzoshandiswa. Inowedzera graphite yakanaka microbial inotakura, kunyanya mukurapa kwemvura kweoiri organic macromolecule kusvibiswa. Nekuda kwekugadzikana kwayo kwemakemikari uye kushandiswazvezve, ine tarisiro yakanaka yekushandisa.
3, mushonga nekuda kwekuwedzera graphite ine adsorption hunhu hweorganic uye biological macromolecules, ine huwandu hwakasiyana hwemashandisiro ekushandisa mune biomedical zvinhu.
4, high energy battery material expanders graphite sechinhu chebhatiri, ndiko kushandiswa kweexpander graphite layer reaction of free energy change into electric energy.Usually expandable graphite inoshandiswa se cathode, lithium seanode, kana kuwedzera graphite composite sirivha oxide se cathode, zinc se anode.Fossil fluoride ink, graphite yakadai seAuC halide uye graphite yeAuC yave yakawedzera asidhi yeAuC yesimbi uye graphite yeAuC yakawedzerwa inoshandiswa mumabhatiri.
5, inodzivirira moto
Nekuda kwekuwedzera kwekuwedzera kwegraphite uye nekupisa kwayo kupisa kwepamusoro, iyo inokwidziridzwa graphite inova yakanakisa yekuisa chisimbiso uye inoshandiswa zvakanyanya mumoto chisimbiso strip. Kune maviri mafomu makuru: yekutanga ndeyekuwedzera kwezvinhu zvegraphite uye zvigadzirwa zverubha, inorganic flame retardant, accelerator, vulcanization agent, inosimbisa musanganiswa, vulcanization yakagadzirwa, vulcanization agent, vulcanization yakagadzirwa, vulcanization agent. Kuwedzera chisimbiso rubber strip, inonyanya kushandiswa pamoto magonhi, moto Windows uye dzimwe nguva.Kuwedzera chisimbiso tambo inogona kuvharidzira kuyerera kweutsi kubva pakutanga kusvika kumagumo pakamuri tembiricha uye moto.Imwe igirazi fiber bhendi semutakuri, iyo inowedzera girafu ine binder yakasungirirwa pamutakuri, iyo inonamira inoumbwa pakupisa kwepamusoro carbonized zvinhu zvinopihwa zvinobudirira zvinodzivirira kuvharisa moto. mikova, asi haikwanise kuvharira kuyerera kwemhepo inotonhorera gasi pane tembiricha yekamuri kana yakaderera tembiricha, saka inofanira kushandiswa nekamuri tembiricha sealant.
Iyo flame retardant inokwidziridzwa graphite yakanaka murazvo wemoto wepurasitiki zvinhu. Iine hunhu hwekusina-chepfu uye kusvibiswa-isina. Inogona kuwana yakanakira murazvo unodzoreredza mhedzisiro kana uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchi . yakaparadzaniswa nemwaranzi yekupisa uye kusangana kweokisijeni; Iyo asidhi radicals muinterlayer inoburitswa panguva yekuwedzera, iyo inosimudzirawo carbonization yeiyo substrate, kuitira kuti iwane mhedzisiro yakanaka kuburikidza neakasiyana nzira dzinodzoreredza moto.
Chibhegi chinopisa moto, mapurasitiki emhando yekudzivirira moto, mhete yekudzivirira moto nekuti iyo inowedzeredza graphite mukupisa kwepamusoro inokwanisa kuramba kukuvadzwa uye ine mwero wekuwedzera, inogona kushandiswa sebhegi risingapinde moto, mapurasitiki emhando yekudzivirira moto, zvindori zvinodzivirira moto mukuwedzera kunobudirira murazvo zvinodzoreredza zvinhu, zvinoshandiswa kuvaka chisimbiso chemoto (senge: kuvharisa pombi yekuvaka, pombi yekugadzira, pombi yemhepo, tambo yegesi, gasi, tambo yekugadzira, gasi remhepo, tambo yekugadzira, gasi, gasi, tambo yemagetsi, tambo yekugadzira, tambo yemagetsi, pombi yekuvaka, gasi, gasi. zviitiko).
Kushandisa muzvokuputira Fine particles of expandable graphite inogona kuwedzerwa kune zvakajairika coatings kuti ibudise zviri nani murazvo wemoto uye anti-static coatings, uye kuvandudza kupisa kwavo kwekushisa kwepamusoro uye kupikisa moto.Kuwanda kwechiedza chisingabatiki kabhoni chikaumbwa mumoto chinogona kunyatsovhara kupisa kwemvura kune substrate uye zvinobudirira kudzivirira substrate. Uyezve, nokuti girafu yemagetsi inogona kudzivirira girafu yemagetsi inogona kudzivirira girafu yemagetsi. kuunganidza, kunoshandiswa kutakura matangi ekuchengetedza petroleum, kuwana maitiro maviri ekudzivirira moto uye static magetsi.
Bhodhi rekudzivirira moto, pepa remoto rinodzivirira uye rinodzivirira kupisa kwepamusoro: musimbi yesimbi yakavharwa ne graphite layer, expatable graphite layer uye metal base pakati pe carbonized adhesive layer, expatable graphite layer yakafukidzwa ne carbonized protective layer.Corrosion resistance, high temperature uye high pressure resistance. Iyo haityi kutonhora nekukurumidza uye nekukurumidza kupisa, uye ine yakanakisa kupisa conduction coefficient. Kupisa kwekushanda ndiko -100 ~ 2 000 ℃.Kuwanda kwekushandiswa, nyore kugadzira, kudhura kwakaderera.Kuwedzera, girafu inowedzerwa yakawedzerwa pakupisa kwepamusoro, yakatsikirirwa graphite mapepa, inoshandiswawo munzvimbo dzekudzivirira moto.
