Xaaladaha isticmaalka garaafka la ballaarin karo
1. Shaabadeynta waxaa lagu qasi karaa garaafka sare ee kaarboonka iyo sulfuric acid iyo nitric acid si loogu daweeyo aashitada, daaweynta kulaylka ka dibna la riixo oo la sameeyay. Garaafyada jilicsan ee la diyaariyey waa qalab cusub oo wax-qabad sare leh, waana nooc ka mid ah nanomaterials oo lagu koray situ. Marka la barbardhigo caag asbestos ah iyo qalab kale oo dhaqameed dhaqameed, waxay leedahay cadaadis wanaagsan, adkeysi, isku-xirnaansho, cufnaanta hoose iyo guryaha kale ee aad u fiican, waxaana loo isticmaali karaa heerkulka sare, suuska sare iyo xaaladaha kale ee adag ee shaqada muddo dheer ayaa la sameeyay. hawada, mishiinada, elektarooniga ah, tamarta nukliyeerka, petrochemical, awoodda korontada, maraakiibta, dhalaalid iyo warshadaha kale.Because waxa uu leeyahay miisaanka fudud, conductive, conductivity kulaylka, caabbinta heerkulka sare, acid iyo caabbinta daxalka alkali, adkeysiga wanaagsan, saliidayn, balaastikada iyo xasiloonida kiimikada iyo guryaha kale ee aad u fiican, oo loo yaqaan "boqorka xiridda" adduunka.
2. Garaafyada la ballaarin karo ee laga helay balaadhinta heerkulka sare ee duurka ilaalinta deegaanka ayaa leh qaab-dhismeedka dalool qani ah iyo waxqabadka adsorption aad u fiican, sidaas darteed waxay leedahay tiro balaadhan oo ah isticmaalka ilaalinta deegaanka iyo biomedicine.The qaab dhismeedka dalool ee graphite la ballaarin karo waxaa loo qaybiyaa laba nooc: dalool furan iyo dalool xiran. Mugga dalool ee graphite balaarin waa ku saabsan 98%, oo inta badan waa dalool weyn oo kala duwan qaybinta size dalool ee 1 ~ 10. 3 nm.Because waa macroporous ah, mesoporous inta badan, si iyo kaarboon firfircoon iyo qalabka kale ee microporous ee sifooyinka adsorption waa different.It ku haboon adsorption wajiga dareere ah, laakiin ma aha wajiga adsorption gaaska ee oleophilic wajiga. graphite. Garaafka la fidin karo waa side microbial wanaagsan, gaar ahaan daaweynta biyaha ee wasakhowga macromolecule organic saliidda. Sababtoo ah xasiloonideeda kiimikada wanaagsan iyo dib u isticmaalida dib loo cusboonaysiin karo, waxay leedahay rajo codsi oo wanaagsan.
3, daawada ay sabab u tahay graphite la ballaarin karo waxay leedahay sifooyinka adsorption ee macromolecules organic iyo noolaha, waxa ay leedahay tiro balaadhan oo ah fursadaha codsiga ee qalabka biomedical.
4, graphite wax batari tamarta sare graphite sida wax batari, waa isticmaalka expanders falcelinta lakabka graphite ee tamarta lacag la'aan ah beddelka energy.Usually graphite graphite loo isticmaalo sida cathode, lithium sida anode, ama graphite ballaarinta graphite ka kooban silver oxide sida cathode, zinc sida anode.Fossil fluoride khad, graphite acid iyo graphite Acid iyo Halil ee baytariyada.
5, dabdemiska
Sababtoo ah ballaarinta graphite la ballaarin karo iyo iska caabbinta heerkulka sare, garaafyada la ballaarin karo waxay noqotaa wax aad u wanaagsan oo lagu xiro waxaana si ballaaran loo isticmaalaa xargaha daboolida dabka inta badan loo isticmaalo albaabada dabka, Dabka Windows iyo marmarka kale. The strip shaabadeynta ballaarinta xannibi kara socodka qiiqa ka bilaabo bilowga ilaa dhamaadka heerkulka qolka iyo fire.The kale waa band fiber galaas sida side, graphite ee la fidin karo la binder ah bonded on side, xabagta sameeyey at heerkul sare wax carbonized ah oo ay bixiso xoogga xiirid ah si wax ku ool ah ayaa looga hortagi karaa graphite sliding, laakiin waxaa si wax ku ool ah u xannibi kara albaabka sliding. gaaska qiiqa qabow ee heerkulka qolka ama heerkul hooseeya, markaa waa in lagu isticmaalo daboolida heerkulka qolka.
Garaafyada la fidin karo ee ololku waa ololka dib u dhigista alaabta caagga ah. Waxay leedahay sifooyin aan sun ahayn iyo wasakh la'aan. Waxay gaari kartaa saamaynta ololka ku habboon marka keligiis la isticmaalo ama lagu qaso ololka kale ee graphite. Expansable graphite wuxuu gaari karaa saameyn isku mid ah ololka, qadarku wuxuu aad uga yar yahay dib-u-celinta ololka caadiga ah. Its mabda'a ficilku waa: heerkulka sare, ballaarinta graphite waxay si degdeg ah u ballaarin kartaa, cabudhinta ololka, iyo graphite-ka waxaa lagu daboolay walxaha kor u kaca. shucaaca kulaylka iyo xidhiidhka oksijiinta;Xeerka aashitada ee interlayer-ka ayaa la sii daayaa inta lagu jiro ballaarinta, taas oo sidoo kale kor u qaadeysa carbonization ee substrate-ka, si loo gaaro natiijooyin wanaagsan iyada oo loo marayo hababka kala duwan ee ololka.
Boorsada aan dabka lahayn, nooca caagga ah ee walxaha xannibaadda dabka, giraanta iska caabinta dabka sababtoo ah graphite-ka la ballaarin karo ee heerkulka sare wuxuu awood u leeyahay inuu iska caabiyo burburka wuxuuna leeyahay heerka ballaarinta sare, waxaa loo isticmaali karaa sida bac dab-damis ah, caag ah nooca caagga ah ee dab-demiska, qaybaha giraanta iska caabbinta dabka ee wax-ku-oolnimada balaadhinta ololka, oo loo isticmaalo dhismaha xiritaanka dabka (sida: xiridda tuubada dhismaha, fiilada, fiilada, gaaska, tuubada gaaska iyo tuubooyinka kale ee hawada).
Codsiga in daahan Qurub Fine ee graphite ballaarinta lagu dari karaa daahan caadiga ah si ay u soo saaraan olol retardant ka fiican iyo daahan anti-static, iyo hagaajinta ay heerkulka sare iska caabin ah iyo dabka iska caabin.The tirada badan ee lakabka carbon aan guban karin iftiin sameeyey in dabka si wax ku ool ah u xannibi kartaa shucaaca kulaylka si substrate ah iyo si wax ku ool ah loo ilaaliyo substrate.In dheer, maxaa yeelay, graphite waa daahan ka hortag ah oo koronto wanaagsan, waayo, graphite waa daahan ka hortagga isticmaalka koronto wanaagsan. Haamaha kaydinta batroolka, si loo gaadho saamaynta laba geesoodka ah ee ka hortagga dabka iyo korontada taagan.
Guddiga ka hortagga dabka, daxalka xaashida dabka u adkaysta iyo heerkulka sare ee saxan u adkaysta: ee saldhigga birta ah ee lagu daboolay lakabka graphite, lakabka graphite ee la saari karo iyo saldhigga birta ee u dhexeeya lakabka xabagta carbonized, lakabka graphite ee la saari karo waxaa lagu daboolay lakabka ilaalinta carbonized. Kama baqanayso qaboojin degdeg ah iyo kuleyl degdeg ah, waxayna leedahay iskudhaf kuleyl ah oo heer sare ah. Heerkulka hawlgalku waa -100 ~ 2 000 ℃. Kala duwanaanta codsiga, fududahay in la soo saaro, qiimo jaban. Intaa waxaa dheer, garaafyada la ballaarin karo oo la ballaariyay heerkulka sare, warqad graphite ah oo la cadaadiyo, ayaa sidoo kale loo isticmaalaa meelaha dabka lagu daboolo.
