Yanayin amfani da graphite mai faɗaɗawa
1. Abun rufewa yana haɗuwa da babban graphite na carbon da maida hankali sulfuric acid da nitric acid don maganin acidification, magani mai zafi sannan kuma an danna shi kuma ya kafa. A m graphite shirya shi ne wani sabon high-yi sealing abu, kuma shi ne wani irin nanomaterials girma a situ.Compared tare da asbestos roba da sauran gargajiya sealing kayan, shi yana da kyau compressibility, resilience, kai bonding, low yawa da sauran kyau kwarai Properties, kuma za a iya amfani da a high zafin jiki, high lalata da sauran matsananci aiki yanayin da aka yi amfani da dogon lokaci da aka gyara da jadawali da aka gyara da aka yi amfani da farantin karfe da aka gyara na dogon lokaci. sararin samaniya, injiniyoyi, kayan lantarki, makamashin nukiliya, petrochemical, wutar lantarki, ginin jirgin ruwa, smelting da sauran masana'antu.Domin yana da nauyin haske, conductive, thermal conductivity, high zafin jiki juriya, acid da alkali lalata juriya, mai kyau resilience, lubrication, filastik da kwanciyar hankali sunadarai da sauran kyawawan kaddarorin, wanda aka sani da "sarkin rufewa" na duniya.
2. The expandable graphite samu ta high zafin jiki fadada a fagen muhalli kariya yana da wani arziki pore tsarin da kyau kwarai adsorption yi, don haka yana da fadi da kewayon amfani a muhalli kariya da biomedicine.The pore tsarin expandable graphite ya kasu kashi biyu iri: bude pore da rufaffiyar pore. The pore girma na expandable graphite ne game da 98%, kuma shi ne yafi manyan pore da pore size rarraba kewayon 1 ~ 10. 3 nm.Because yana da wani macroporous, mesoporous yafi, don haka da kunna carbon da sauran microporous kayan a cikin adsorption halaye ne daban-daban.It ne dace da ruwa lokaci adsorption, amma ba gas lokaci na ruwa adsorption lokaci. adsorption.1 g expatable graphite iya adsorb fiye da 80 g nauyi mai, don haka yana da alamar kare muhalli abu don tsaftacewa gurbataccen mai a kan ruwa surface.A cikin sharar gida magani na sinadarai Enterprises, microorganisms (kwayoyin cuta) ana amfani da sau da yawa. Expandable graphite ne mai kyau microbial m, musamman a cikin ruwa magani na mai Organic macromolecule gurbatawa. Saboda kyakkyawan kwanciyar hankali da sinadarai da sake amfani da shi, yana da kyakkyawan fata na aikace-aikace.
3, magani saboda expandable graphite yana da halaye na adsorption na kwayoyin halitta da macromolecules na halitta, yana da fa'idodin aikace-aikacen da yawa a cikin kayan ilimin halitta.
4, high makamashi baturi abu expanders graphite matsayin baturi abu, shi ne yin amfani da expanders graphite Layer dauki na free makamashi canji a cikin lantarki energy.Usually expandable graphite da ake amfani da matsayin cathode, lithium kamar yadda anode, ko expandable graphite hada azurfa oxide kamar yadda cathode, tutiya a matsayin anode.Fossil fluoride tawada, graphite acid da metal3 aka yi amfani da irin wannan nau'i na graphite. a cikin batura.
5, mai kare wuta
Saboda da expandability na expandable graphite da kuma high zafin jiki juriya, da expandable graphite ya zama mai kyau sealing abu da aka yadu amfani a cikin wuta sealing strip.There akwai biyu main siffofin: na farko shi ne fadada graphite kayan da roba kayan, inorganic harshen wuta retardant, totur, vulcanization wakili, ƙarfafa wakili, filler hadawa na musamman m tsiri, sanya hatimi daban-daban m, vulcanization na vulcanization. yafi amfani da wuta kofofin, wuta Windows da sauran lokuta.The fadada sealing tsiri iya toshe ya kwarara daga hayaki daga farkon zuwa karshen a dakin da zafin jiki da kuma fire.The sauran shi ne gilashin fiber band a matsayin m, da expansible graphite tare da wani ɗaure bonded a kan m, da m kafa a high zafin jiki carbonized abu bayar da karfi karfi iya yadda ya kamata hana graphite sliding kofa zai iya yadda ya kamata hana graphite sliding, amma kofa Yana iya yadda ya kamata hana graphite sliding. iskar gas mai sanyi a dakin da zafin jiki ko ƙananan zafin jiki, don haka dole ne a yi amfani da shi tare da mashin zafin jiki.
Hotunan da za a iya faɗaɗa harshen wuta yana da kyau mai ɗaukar wuta don kayan filastik. Yana da halaye marasa guba da ƙazanta. Yana iya cimma manufa mai kyau harshen retardant sakamako a lokacin da amfani da shi kadai ko gauraye da sauran harshen retardants.Expansable graphite iya cimma wannan harshen retardant sakamako, adadin ne da yawa kasa da talakawa harshen retardant.Its ka'idar aiki ne: a high zafin jiki, da fadada na graphite iya fadada da sauri, suffocating da harshen wuta, da kuma graphite da aka rufe da fadada abu daga surface na graphite da aka rufe da surface na graphite. thermal radiation da oxygen lamba; Ana saki radicals acid a cikin interlayer a lokacin fadadawa, wanda kuma yana inganta carbonization na substrate, don samun sakamako mai kyau ta hanyoyi daban-daban na harshen wuta.
Fireproof jakar, roba irin fireproof block abu, wuta juriya zobe saboda expandable graphite a high zafin jiki yana da ikon yin tsayayya da lalacewa da kuma yana da wani babban fadada kudi, za a iya amfani da matsayin fireproof jakar, roba irin fireproof block abu, wuta juriya zobe aka gyara a cikin tasiri fadada harshen retardant abu, amfani da ginin wuta sealing (kamar: sealing yi bututu, na USB, waya, gas, gas bututu, da sauran iska bututu lokaci).
Aikace-aikace a cikin coatings Fine barbashi na expandable graphite za a iya ƙara zuwa talakawa coatings don samar da mafi harshen wuta retardant da anti-a tsaye coatings, da kuma inganta su high zafin jiki juriya da kuma wuta resistance.The babban adadin haske wadanda ba combustible carbon Layer kafa a cikin wuta iya yadda ya kamata toshe zafi radiation zuwa substrate da kuma yadda ya kamata kare substrate.In Bugu da kari, saboda graphite ne mai kyau shafi amfani da lantarki conductor hanawa, saboda graphite ne mai kyau da ake amfani da wani lantarki conductor hanawa. tankunan ajiyar man fetur, don cimma sakamako biyu na rigakafin gobara da wutar lantarki.
Wuta rigakafin jirgin, wuta takarda lalata resistant da kuma high zafin jiki resistant farantin: a cikin karfe tushe liyi tare da expatable graphite Layer, expatable graphite Layer da karfe tushe tsakanin carbonized m Layer, expatable graphite Layer an rufe carbonized m Layer.Corrosion juriya, high zafin jiki da kuma high matsa lamba resistance.At lokaci guda, shi kuma za a iya amfani da kullum a low zazzabi. Ba ya jin tsoron sanyi mai sauri da dumama mai sauri, kuma yana da kyakkyawan yanayin sarrafa zafi. Yawan zafin jiki na aiki shine -100 ~ 2 000 ℃.Wide kewayon aikace-aikacen, mai sauƙin ƙira, ƙananan farashi. Bugu da ƙari, graphite mai faɗaɗawa ya faɗaɗa a babban zafin jiki, takarda graphite da aka guga, kuma ana amfani dashi a wurare masu rufe wuta.
