Chaza i-high-purity graphite kanye ne-graphite ebunjiwe

Iyini i-high-purity graphite kanye ne-graphite ebunjiwe? Kukholakala ukuthi abantu abaningi abazi nge-high-purity graphite. Manje, umqondisi uLi we-Jiuyi Seal uzochaza ukuthi iyini i-graphite ehlanzekile kakhulu nokuthi iyini i-graphite ebunjiwe:

I-graphite yokuhlanzeka okuphezulu, eyaziwa nangokuthi i-graphite ebunjiwe, isho ukuthi okuqukethwe kwekhabhoni yegraphite kungaphezu kuka-99.99%, futhi inokuqhuba kahle kakhulu, ukumelana nokushisa, ukumelana ne-oxidation, inkomba ephansi ye-resistor, ukumelana nokugqwala, ukuhlanzeka okuphezulu, ukuzigcoba, ukushisa. ukumelana nokushaqeka, i-anisotropy, futhi ilungele ukucutshungulwa kwemishini okunembe kakhulu. Amakristalu wesilinganiso sezinhlanzi ze-graphite anemininingwane eminingi, mancane futhi ane-ductile, futhi anezakhiwo ezinhle kakhulu zomzimba. Kuyinto efanelekile ye-carbon free raw material, esetshenziswa kabanzi ku-aerospace, i-solar photovoltaic kanye ne-semiconductor materials, i-steel rolling, amathuluzi e-alloy eqinile kanye ne-electronic device mold sintering, ukukhishwa kwenhlansi, ingilazi e-laminated, imishini yemishini, amandla nezinye izimboni zokukhiqiza.

I-graphite ehlanzekile kakhulu inezinzuzo ezihlukile ekukhiqizeni nasekucutshungulweni kwezingxenye ze-heater kagesi, ukwakha ukwakhiwa kwe-die, izindlawu zezinto zensimbi ezihlanzekile kakhulu zezitshalo ezincibilikayo, izifudumezi zikagesi zezithando zomlilo zekristalu eyodwa, i-wire cut EDM graphite, i-sintering dies, i-rectifier tube anodizing. , ukumbozwa kwensimbi, izindlawu ze-graphite zobuchwepheshe be-semiconductor, ukuthumela amashubhu okulungisa, i-thyratron, ne-graphite anodizing kanye negridi yama-ballasts e-mercury arc. Ikakhulukazi, i-graphite ehlanzekile enezici ezinkulu, amamodeli kanye nekhwalithi ephezulu, njengengxenye yempahla eluhlaza, inendawo ebanzi yasendlini ukuze isetshenziswe emkhakheni wesayensi nobuchwepheshe obusha, futhi inethuba elibanzi lokufaka isicelo.

Izindlela zokuhlanzeka okuphezulu kwe-graphite zingahlukaniswa zibe izigaba ezimbili: eyodwa ukuhlanzwa okumanzi, okuhlanganisa indlela enzima ephakathi, i-asidi eqinile kanye nendlela eyisisekelo eqinile, kanye nendlela ye-hydrogen acid; Okunye ukuhlanzwa komlilo, okuhlanganisa indlela yokubala ye-isopropyl titanate kanye nendlela yokushisa ephezulu.

Ukuze uthole i-high-purity graphite, ukusetshenziswa okuyinhloko kwe-graphite ebunjiwe yilezi:

Isetshenziswa kakhulu ezintweni zokufaka eziphikisayo nezimbozwe zokwakha embonini yensimbi neyensimbi, isiqinisi sezinto ezingavuthiwe eziqhumayo embonini yezokuvikela kazwelonke, umthofu wepensela embonini yokukhanya, ibhulashi le-motor carbon embonini yemishini kagesi, ibanga likagesi embonini yebhethri elishajekayo, i-metal catalyst anti -i-corrosion agent ye-organic fertilizer industry, njll. Ngemva kokukhiqizwa nokucubungula, i-graphite ephezulu-purity ingase futhi ikhiqize imikhiqizo emisha yesayensi nezobuchwepheshe efana ne-graphite emulsion, izimpawu zenjoloba ze-graphite kanye nezinto ze-polymer, imikhiqizo ye-graphite, i-graphite antifriction preservatives, futhi ibe ukhiye. izinto zokusetshenziswa zamabhizinisi ezimayini emkhakheni wemboni ngayinye.
