Maitiro ekushandisa graphite anogona kuwedzerwa
1. Chinhu chinovhara chinosanganiswa negrafiti ine kabhoni yakawanda uye sulfuric acid yakawanda uye nitric acid yekurapa acidization, kupisa uye yobva yadzvanywa yogadzirwa. Grafiti inochinjika yakagadzirwa chinhu chitsva chinovhara chine simba repamusoro, uye imhando ye nanomaterials inorimwa munzvimbo. Kana ichienzaniswa nerabha yeasbestos nezvimwe zvinhu zvechinyakare zvekuvhara, ine kudzvanywa kwakanaka, kusimba, kuzvibatanidza, kusimba kwakaderera nezvimwe zvinhu zvakanaka, uye inogona kushandiswa mumamiriro ekupisa akakwira, kuora kwakanyanya uye mamwe mamiriro ekushanda akaoma kwenguva yakareba. Maplate egrafiti nezvinhu zvinovhara zvakagadzirwa nayo zvinoshandiswa zvakanyanya mundege, michina, zvemagetsi, simba renyukireya, petrochemical, simba remagetsi, kuvaka ngarava, kunyungudutsa uye mamwe maindasitiri. Nekuti ine huremu hwakareruka, conductive, thermal conductivity, high tembiricha resistance, acid nealkali corrosion resistance, good resistance, lubrication, plasticity uye chemical stability nezvimwe zvinhu zvakanaka, inozivikanwa se "mambo we sealing" wepasi rose.
2. Graphite inowedzerwa inowanikwa nekuwedzera tembiricha yepamusoro mumunda wekuchengetedza nharaunda ine chimiro chakapfuma chepore uye kugona kwakanaka kwe adsorption, saka ine mashandisirwo akasiyana-siyana mukuchengetedza nharaunda uye biomedicine. Chimiro chepore chegraphite inowedzerwa chakakamurwa kuita mhando mbiri: pore yakavhurika uye pore yakavharika. Vhoriyamu yepore yegraphite inowedzerwa inenge 98%, uye inonyanya kuva pore yakakura ine saizi yekupararira kwepore ye1 ~ 10.3 nm. Nekuti ipore yakawanda, mesoporous inonyanya, saka activated carbon nezvimwe zvinhu zvidiki-diki muhunhu hwe adsorption zvakasiyana. Yakakodzera liquid phase adsorption, asi kwete gas phase adsorption. Iyo oleophilic uye hydrophobic mu liquid phase adsorption. 1 g expatable graphite inogona kunyudza mafuta anodarika 80 g, saka ichinhu chinovimbisa chekuchengetedza nharaunda chekuchenesa kusvibiswa kwemafuta pamusoro pemvura. Mukurapa kwemakemikari emvura yakasviba, tupukanana (mabhakitiriya) tinowanzo shandiswa. Graphite inowedzerwa inotakura utachiona hwakanaka, kunyanya mukurapa mafuta mumvura nekusvibiswa kwemakemikari emuchadenga. Nekuda kwekugadzikana kwayo kwemakemikari uye kushandiswazve, ine mukana wakanaka wekushandiswa.
3, mushonga une graphite inowedzerwa ine hunhu hwekunyungudutsa hwema macromolecule ezvisikwa uye ezvebhayoloji, ine mikana yakawanda yekushandisa mune zvigadzirwa zvekurapa.
4, graphite inoshandiswa nebhatiri ine simba rakawanda sebhatiri, kushandiswa kwegirafiti yekuwedzera girafiti yekuchinja simba remagetsi kuita simba remagetsi. Kazhinji girafiti inowedzerwa inoshandiswa se cathode, lithium se anode, kana girafiti inowedzerwa inosanganiswa silver oxide se cathode, zinc se anode. Inki ye fluoride yefossil, graphite acid uye girafiti inowedzerwa yesimbi halides dzakadai seAuCl3 neTiF4 zvakashandiswa mumabhatiri.
5, chinhu chinodzivirira moto
Nekuda kwekuwedzera kwegrafiti inowedzerwa uye kuramba kwayo kupisa kwakanyanya, grafiti inowedzerwa inova chinhu chakanaka chekuvhara uye inoshandiswa zvakanyanya muchikamu chekuvhara moto. Kune mhando mbiri huru: yekutanga ndeyekuwedzera kwezvinhu zvegrafiti nezvinhu zverabha, inorganic flame retardant, accelerator, vulcanization agent, reinforcement agent, filler mixing, vulcanization, molding, yakagadzirwa nemaitiro akasiyana-siyana echikamu cherabha chekuvhara expansion, chinonyanya kushandiswa kumagonhi emoto, mahwindo emoto nezvimwe zviitiko. Chikamu chekuvhara expansion chinogona kudzivirira kuyerera kweutsi kubva pakutanga kusvika kumagumo patembiricha yemumba nemoto. Chimwe igirazi fiber band semutakuri, grafiti inowedzerwa ine binder yakasungirirwa pamudziyo wekutakura, namatidziro inoumbwa patembiricha yepamusoro yakagadzirwa necarbonized material inopihwa nesimba rekucheka inogona kudzivirira graphite kutsvedza. Inonyanya kushandiswa kumagonhi emoto, asi haigone kudzivirira kuyerera kwemhepo inotonhora patembiricha yemumba kana tembiricha yakaderera, saka inofanira kushandiswa nesealant yemumba.
Graphite inowedzerwa inodzoreredza moto inodzivirira moto zvakanaka pakushandisa zvinhu zvepurasitiki. Ine hunhu hwekuti haina chepfu uye haina kusvibiswa. Inogona kuwana mhedzisiro yakanaka yekudzora moto kana ikashandiswa yoga kana kusanganiswa nezvimwe zvinodzora moto. Graphite inowedzerwa inogona kuwana mhedzisiro yakafanana yekudzora moto, huwandu hwayo hushoma pane hunowanzo dzora moto. Nheyo yayo yekuita ndeyekuti: pakupisa kwakanyanya, kuwedzera kwegraphite kunogona kukura nekukurumidza, kuchidziisa moto, uye zvinhu zvinowedzerwa negraphite zvinogadzirwa nayo zvinofukidzwa pamusoro pesubstrate, zvakaparadzaniswa nemwaranzi inopisa uye kusangana kweokisijeni; Asidhi radicals muinterlayer inoburitswa panguva yekuwedzera, izvo zvinosimudzirawo carbonization yesubstrate, kuitira kuti pave nemhedzisiro yakanaka kuburikidza nenzira dzakasiyana-siyana dzinodzora moto.
Bhegi risingapisi moto, zvinhu zvepurasitiki zvinodzivirira moto, mhete inodzivisa moto nekuti girafiti inokura kana yapisa zvakanyanya ine simba rekudzivirira kukuvara uye ine mwero wekuwedzera wakakwira, inogona kushandiswa sebhegi risingapisi moto, zvinhu zvepurasitiki zvinodzivirira moto, zvikamu zvemhete zvinodzivirira moto muzvinhu zvinodzivirira moto zvinobudirira, zvinoshandiswa pakuvhara moto muchivako (zvakadai se: kuvhara pombi yekuvaka, tambo, waya, gasi, pombi yegesi, pombi yemhepo inopinda nepaburi nezvimwewo).
Kushandiswa muzvipfeko Zvidimbu zvakanaka zvegrafiti inogona kuwedzerwa muzvipfeko zvakajairika kuti zvigadzire zvipfeko zviri nani zvinodzivisa moto uye zvinopesana nekupisa, uye kuvandudza kudzivirira kwavo kupisa kwakanyanya uye kudzivirira moto. Huwandu hwakawanda hwekabhoni isingatsve inogadzirwa mumoto hunogona kudzivirira kupisa kwepasi pevhu uye kudzivirira substrate zvinobudirira. Pamusoro pezvo, nekuti graphite inyanzvi yemagetsi yakanaka, chipfeko ichi chinogona kudzivirira kuunganidzwa kwemagetsi, anoshandiswa mumatangi ekuchengetera peturu, kuti pave nemhedzisiro mbiri yekudzivirira moto uye magetsi asingatsve.
Bhodhi rekudzivirira moto, rinopikisa ngura pamapepa emoto uye ndiro inodzivirira kupisa kwakanyanya: muchigadziko chesimbi chakafukidzwa negrafiti layer inochinjika, graphite layer inochinjika uye simbi pakati pe carbonized adhesive layer, graphite layer inochinjika yakafukidzwa necarbined protective layer. Kupikisa ngura, kupisa kwakanyanya uye kumanikidzwa kwakanyanya. Panguva imwe chete, inogonawo kushandiswa zvakajairika pakupisa kwakaderera. Haityi kutonhora nekukurumidza uye kupisa nekukurumidza, uye ine coefficient yakanaka yekupisa. Tembiricha yekushanda ndeye -100 ~ 2 000 ℃. Mhando dzakasiyana dzekushandiswa, dziri nyore kugadzira, mutengo wakaderera. Pamusoro pezvo, graphite inochinjika inochinjika inochinjika pakupisa kwakanyanya, graphite paper yakadzvanywa, inoshandiswawo munzvimbo dzinodzivirira moto.
