Iimeko zokusetyenziswa kwegraphite ekwandiswayo
1. Izinto zokutywina zixutywe kunye ne-carbon graphite ephezulu kunye ne-sulfuric acid egxininisiweyo kunye ne-nitric acid yonyango lwe-acidification, unyango lobushushu kwaye emva koko ucinezele kwaye wenze. I-graphite eguquguqukayo elungiselelwe yinto entsha yokutywinwa kokusebenza okuphezulu, kwaye luhlobo oluthile lwe-nanomaterials olukhulile kwi-situ.Xa kuthelekiswa nerubha ye-asbestos kunye nezinye izinto zokutywinwa zendabuko, inokunyamezela okulungileyo, ukuqina, ukuzibophelela, ukuxinana okuphantsi kunye nezinye iimpawu ezibalaseleyo, kwaye zingasetyenziselwa kwiqondo lokushisa eliphezulu, ukubola okuphezulu kunye nezinye iiplati ezide kunye neemeko zokusebenza ezibukhali kunye ne-plateite yexesha elide kunye neemeko zokusebenza ezilukhuni. isetyenziswa kakhulu kwi-aerospace, oomatshini, i-electronics, amandla enyukliya, i-petrochemical, amandla ombane, ukwakha iinqanawa, ukunyibilika kunye nezinye i-industries.Ngenxa yokuba inobunzima obulula, i-conductive, i-thermal conductivity, ukumelana nobushushu obuphezulu, ukuxhathisa ukubola kwe-asidi kunye ne-alkali, ukomelela okuhle, ukuthambisa, iplastiki kunye nokuzinza kweekhemikhali kunye nezinye iipropati ezibalaseleyo zehlabathi, ezaziwa ngokuba yi-sea.
2. I-graphite enwebekayo efunyenwe ngokunyuka kweqondo lokushisa eliphezulu kwintsimi yokukhusela indalo inesakhiwo esityebileyo se-pore kunye nokusebenza okugqwesileyo kwe-adsorption, ngoko inoluhlu olubanzi lokusetyenziswa ekukhuseleni kwendalo kunye ne-biomedicine. Umthamo wepore yegraphite eyandisiweyo imalunga nama-98%, kwaye ubukhulu becala ipore enkulu kunye nobungakanani bepore ububanzi bokuhanjiswa kwe-1 ~ 10. 3 nm.Kuba i-macroporous, i-mesoporous ubukhulu becala, ngoko kunye nekhabhoni esebenzayo kunye nezinye izinto ezincinci kwiimpawu ze-adsorption ziyahluka.Ifanelekile kwisigaba solwelo se-adsorption kunye nesigaba se-adsorption. I-hydrophobic kwisigaba se-adsorption ye-liquid.1 g i-graphite ekhutshwayo ingabhengeza ngaphezu kwe-80 g yeoli enzima, ngoko yinto ethembisayo yokukhusela indalo yokucoca ukungcola kweoli kwindawo yamanzi. Igraphite eyongezelekayo ngumthuthi olungileyo we-microbial, ngakumbi kunyango lwamanzi lwe-oyile ye-organic macromolecule yongcoliseko. Ngenxa yozinzo oluhle lweekhemikhali kunye nokusetyenziswa kwakhona okuvuselelekayo, inethemba elihle lokusetyenziswa.
I-3, iyeza ngenxa yegraphite eyandiswayo ineempawu ze-adsorption ze-organic and biological macromolecules, inoluhlu olubanzi lwamathemba okusebenza kwizinto eziphilayo.
I-4, izinto zebhetri zamandla aphezulu izandisi zegraphite njengesixhobo sebhetri, kusetyenziso lwezandisi zegraphite umaleko wokusabela kwenguqu yamandla yasimahla ibe yi-energy yombane.Ngokuqhelekileyo igraphite ekwandiswayo isetyenziswa njenge-cathode, i-lithium njenge-anode, okanye i-graphite eyandisiweyo edibeneyo yesilivere ye-oxyde njenge-cathode, i-zinc njenge-anode.Fossil fluoride inki, i-graphite ye-asidi ye-AuC kunye ne-asidi ye-graphite ye-AuC kunye ne-asidi ye-graphite ye-AuC kunye ne-asidi ye-graphite ye-AuC kunye ne-asidi ye-graphite ye-asidi esetyenziswa kwiibhetri.
I-5, i-retardant yomlilo
Ngenxa yokwandiswa kwegraphite ekwandiswayo kunye nokumelana nobushushu obuphezulu, igraphite enwebekayo iba yinto ebalaseleyo yokutywinwa kwaye isetyenziswa ngokubanzi kumgca wokutywinwa komlilo. Kukho iifom ezimbini eziphambili: eyokuqala kukwandiswa kwezixhobo zegraphite kunye nezixhobo zerabha, i-inorganic flame retardant, i-accelerator, i-agent ye-vulcanization, i-agent yokuqinisa, i-agent yokudibanisa, i-ejenti yokuqinisa, i-ejenti yokudibanisa, i-ejenti yokuqinisa, i-agent yokuxuba, i-ejenti yokuqinisa Ukwandiswa komcu werabha wokutywina, ikakhulu esetyenziselwa iingcango zomlilo, iiWindows zomlilo kunye nezinye izihlandlo.Umcu wokutywina wokwandisa unokuthintela ukuhamba komsi ukusuka ekuqaleni ukuya ekupheleni kwiqondo lobushushu begumbi kunye nomlilo.Enye ibhendi yefiber yeglasi njengomphathi, igraphite eyandisiweyo ene-binder edityanisiweyo kwi-carrier, i-adhesive eyakhiwe kwiqondo eliphezulu lobushushu obuphezulu bekhabhonithi inokuthintela ngokuyintloko ukunyanzeliswa kwe-shear. iingcango, kodwa ayikwazi ukuthintela ngokufanelekileyo ukuhamba kwegesi ebandayo yegesi kwiqondo lokushisa okanye ubushushu obuphantsi, ngoko ke kufuneka isetyenziswe kunye ne-sealant yeqondo lokushisa.
Igraphite ekwaziyo ukwandisa idangatye yinto elungileyo yokubuyisela idangatye kwizinto zeplastiki. Ineempawu zokungabi natyhefu kunye nongcoliseko. Iyakwazi ukufezekisa umphumo ofanelekileyo wokulahla ilangatye xa isetyenziswe yodwa okanye ixutywe kunye nezinye i-flame retardants.I-graphite ekwandiswayo inokufezekisa umphumo ofanayo we-flame retardant, isixa sincinci kakhulu kune-flame-retardant eqhelekileyo. ekwanti kwimitha ye-thermal kunye noqhagamshelwano lwe-oxygen;I-acid radicals kwi-interlayer ikhululwe ngexesha lokwandiswa, nto leyo ekhuthaza i-carbonization ye-substrate, ukuze kuphunyezwe iziphumo ezilungileyo ngeendlela ezahlukeneyo ze-flame retardant.
Ibhegi yomlilo, uhlobo lweplastiki yezinto ezingatshiyo, umsesane wokumelana nomlilo ngenxa yokuba igraphite enwebekayo kubushushu obuphezulu inamandla okuxhathisa umonakalo kwaye inezinga eliphezulu lokwandiswa, ingasetyenziswa njengengxowa engatshiyo, uhlobo lweplastiki yezinto ezingatshiyo, ikhonkco lokumelana nomlilo kwisixhobo sokwandiswa kwedangatye elisebenzayo, elisetyenziselwa ukwakha ukutywinwa komlilo (ezifana noku: umbhobho wokutywina, umbhobho wokwakha, umbhobho womoya, intambo yomoya, i-gas, intambo yomoya, intambo yombane, intambo yombane kunye negesi yegesi, amaxesha).
Isicelo kwiingubo Amasuntswana amahle egrafu enwetshiweyo anokongezwa kwiingubo eziqhelekileyo zokuvelisa i-flame retardant kunye ne-anti-static, kunye nokuphucula ukuxhathisa ubushushu obuphezulu kunye nokumelana nomlilo.Isixa esikhulu sokukhanya kwekhabhoni engatshiyo enziwe emlilweni inokuthintela ngokufanelekileyo ukushisa kwemitha kwi-substrate kwaye ikhusele ngokufanelekileyo i-substrate.Ukongezelela, ngenxa yokuba i-electrostatic conductor inokuthi ithintele i-electrostatic conductor. ukuqokelela, okusetyenziselwa iitanki zokugcina i-petroleum, ukuphumeza umphumo ombini wokuthintela umlilo kunye nombane ongatshintshiyo.
Ibhodi yokuthintela umlilo, i-fire paper corrosion resistant kunye ne-high high temperatures resistant plate: kwisiseko sesinyithi esine-graphite layer, i-graphite layer kunye nesiseko sesinyithi phakathi kwe-carbonized adhesive layer, i-graphite layer igutyungelwe nge-carbonized layer.I-Corrosion resistance, ubushushu obuphezulu kunye noxinzelelo oluphezulu. Ayikoyiki ukupholisa ngokukhawuleza kunye nokufudumeza ngokukhawuleza, kwaye ine-coefficient yokuqhuba ubushushu obugqwesileyo. Ubushushu bokusebenza buyi-100 ~ 2 000 ℃.Uluhlu olubanzi lwesicelo, kulula ukwenza, ixabiso eliphantsi.Ukongezelela, i-graphite eyandisiweyo eyandisiweyo kwiqondo lokushisa eliphezulu, iphepha legraphite eliciniweyo, likwasetyenziswa kwiindawo zokucima umlilo.
