Urupapuro rwa Graphite, nkibikoresho byo mu rwego rwo hejuru - bikoreshwa mu nganda, bikoreshwa cyane mubice nka metallurgie, injeniyeri yimiti, semiconductor, ningufu nshya. Guhitamo ibikoresho bigira ingaruka ku buryo butaziguye ibikoresho byizewe, igihe cyo kubaho, no gukora neza. Guhitamo ibikoresho bya siyansi bisaba gutekereza cyane kubintu byinshi, birimo ubushyuhe bwumuriro, kurwanya ruswa, imbaraga za mashini, nigiciro.
Based on substrate type, graphite sheet is primarily categorized into three types: natural graphite, artificial graphite, and composite graphite. Natural graphite has a high purity (typically >95%) hamwe nubushuhe buhebuje bwumuriro, ariko imbaraga zubukanishi zo hasi. Irakwiriye gukoreshwa nubushyuhe bwumuriro hamwe nubushobozi buke bwimitwaro, nkibikoresho bya electrode kumatanura yumuriro. Igishushanyo mbonera, gitunganijwe binyuze murwego rwo hejuru - uburyo bwo gushushanya ubushyuhe, bufite ubucucike buri hejuru (1.8-22.2 g / cm³) n'imbaraga zo kwikuramo (kugeza kuri MPa 30). Itanga kandi imbaraga zidasanzwe - zirwanya ubushyuhe (bushobora gukoresha igihe kirekire - gukoresha igihe cy'ubushyuhe bugera kuri dogere 3000), bigatuma ihitamo neza kumashanyarazi ya reaction ya reaction hamwe nuduce twinshi mu itanura rimwe rya -. Gukora grafite, wongeyeho imbaraga nka fibre ya karubone nifu yicyuma, irusheho kuringaniza imbaraga no kwambara, byerekana imikorere yayo myiza mubwato bwa grafite kubwinganda zifotora hamwe nibikoresho bya semiconductor.
Microstructure yibikoresho nayo ni ngombwa. Hejuru - grafite isuku (ibirimo ivu<20 ppm) effectively avoids contamination from metal impurities and is suitable for high-temperature load platforms in semiconductor manufacturing. Isotropic graphite, through isostatic pressing, ensures uniform three-dimensional properties, making it particularly suitable for heat dissipation components in precision molds. For highly corrosive environments (such as hydrofluoric acid and molten alkali), modified graphite sheets impregnated with resin or metal coatings are used, which can improve permeability by 3–5 times.
Kubijyanye nubukungu, inganda zisanzwe - urwego rwubukorikori bwa artite (ubucucike bwa 1,6 g / cm³) rugura kimwe - kimwe cya gatatu cya - cyera gikandamijwe na grafite, ariko igihe cyacyo gishobora kugabanywa hejuru ya 40%. Mubikorwa byubwubatsi, ingamba "zo gutoranya ibikoresho" zikoreshwa kenshi: hejuru - grafite isuku ikoreshwa muburyo bwo guhuza amakuru kugirango habeho ubuziranenge, mugihe igishushanyo gisanzwe gikoreshwa mubice byubatswe kugirango bigabanye ibiciro.
Muncamake, guhitamo ibikoresho bya plaque ya grafite bigomba gushingira kubikorwa bisabwa kugirango ibintu bishoboke, ushake uburinganire bwiza hagati yubushyuhe bwumuriro, kurwanya ruswa, imbaraga za mashini nigiciro, no kongera inyungu zubuhanga muburyo bwa siyanse bujyanye nibintu bifatika.
