Raws li ib qho kev ntxhib los mos ntawm carbon, graphite yog ze rau peb lub neej, thiab cov neeg zoo tib yam yog cov cwj mem qhuav, qhuav roj carbon rods thiab lwm yam. Txawm li cas los xij, graphite muaj kev siv tseem ceeb hauv kev lag luam tub rog, cov ntaub ntawv refractory, metallurgical kev lag luam, tshuaj lom neeg kev lag luam thiab lwm yam.
Graphite muaj ob qho tib si hlau thiab tsis yog xim hlau: graphite raws li tus neeg xyuas pib zoo ntawm thermoelectricity qhia txog cov yam ntxwv hlau; Cov yam ntxwv uas tsis yog xim hlau yog qhov kub tsis kam, siab thermal stability, tshuaj inertness thiab lubricity, thiab nws siv kuj dav heev.
Main daim ntawv thov teb
1, cov khoom siv refractory
Hauv kev lag luam metallurgical, nws yog siv los ua cov khoom siv refractory thiab tiv thaiv tus neeg sawv cev rau steel ingot. Vim tias graphite thiab nws cov khoom muaj cov khoom ntawm qhov kub thiab txias tsis kam thiab lub zog siab, nws yog siv hauv kev lag luam metallurgical los ua graphite crucible, steel rauv hauv ob sab phlu, tiv thaiv slag thiab nruam casting.
2, metallurgical casting kev lag luam
Hlau thiab casting: Graphite yog siv los ua carburizer hauv kev lag luam steelmaking.
Nyob rau hauv casting, graphite yog siv rau casting, sanding, molding cov ntaub ntawv: vim lub me me coefficient ntawm thermal expansion ntawm graphite, siv graphite li casting xim, casting loj yog qhov tseeb, qhov nto yog du, casting tawg thiab pores yog. txo, thiab tawm los yog siab. Tsis tas li ntawd, graphite yog siv rau hauv kev tsim cov hmoov metallurgy, superhard alloys; Kev tsim cov khoom siv carbon.
3. Kev lag luam tshuaj
Graphite muaj kev ruaj ntseg zoo. Cov txheej txheem tshwj xeeb graphite muaj cov yam ntxwv ntawm corrosion kuj, zoo thermal conductivity thiab tsis tshua muaj permeability. Kev siv cov graphite los ua cov kav dej graphite tuaj yeem ua kom cov tshuaj tiv thaiv ib txwm muaj thiab ua tau raws li qhov xav tau ntawm kev tsim cov tshuaj purity siab.
4, Kev lag luam hluav taws xob thiab hluav taws xob
Siv rau hauv kev tsim cov hmoov graphite electrode, txhuam, roj teeb, lithium roj teeb, roj cell zoo electrode conductive khoom, anode phaj, hluav taws xob qws, carbon tube, graphite gasket, xov tooj qhov chaw, rectifier zoo electrode, electromagnetic shielding conductive plastics, tshav kub. exchanger Cheebtsam thiab TV duab tube txheej. Ntawm lawv, graphite electrode yog dav siv rau smelting ntau yam alloys; Tsis tas li ntawd, graphite yog siv los ua cathode ntawm electrolytic hlwb rau electrolysis ntawm hlau xws li magnesium thiab txhuas.
Tam sim no, fluorine fossil inks (CF, GF) tau siv dav hauv cov khoom siv roj teeb uas muaj zog, tshwj xeeb tshaj yog CF0.5-0.99 fluorine fossil inks, uas tsim nyog rau kev ua cov khoom siv anode rau cov roj teeb uas muaj zog, thiab cov roj teeb me me.
5. Atomic zog, aerospace thiab tiv thaiv kev lag luam
Graphite muaj lub siab melting point, stability, corrosion kuj thiab zoo kuj rau A-rays thiab neutron deceleration kev ua tau zoo, siv nyob rau hauv lub nuclear kev lag luam ntawm graphite cov ntaub ntawv hu ua nuclear graphite. Muaj cov neutron moderators rau atomic reactors, reflectors, kub lub tog raj kheej number case rau isotope ntau lawm, spherical graphite rau kub kub cua txias reactors, nuclear reactor thermal Cheebtsam sealing gaskets thiab tej blocks.
Graphite yog siv nyob rau hauv thermal reactors thiab, cia siab tias, fusion reactors, qhov twg nws yuav siv tau raws li ib tug neutron moderator nyob rau hauv lub roj cheeb tsam, raws li ib tug reflector khoom nyob ib ncig ntawm lub roj cheeb tsam, thiab raws li ib tug structural khoom nyob rau hauv lub core.
Tsis tas li ntawd, graphite kuj tseem siv rau hauv kev tsim cov khoom siv hluav taws xob ntev lossis qhov chaw foob pob hluav taws cov ntaub ntawv, cov khoom siv hauv aerospace, rwb thaiv tsev kub thiab hluav taws xob tiv thaiv cov ntaub ntawv, kev tsim cov roj foob pob hluav taws cav tail nozzle caj pas liner, thiab lwm yam. ntau lawm ntawm aviation txhuam, thiab spacecraft DC motors thiab aerospace khoom qhov chaw, satellite xov tooj cua kev twb kev txuas teeb liab thiab conductive cov ntaub ntawv; Hauv kev lag luam tiv thaiv, nws tuaj yeem siv los tsim cov bearings rau cov submarines tshiab, tsim cov purity graphite rau lub teb chaws tiv thaiv, graphite foob pob, qhov ntswg cones rau stealth aircraft thiab missiles. Tshwj xeeb, graphite foob pob tuaj yeem ua rau tuag tes tuag taw kev ua haujlwm ntawm substations thiab lwm yam khoom siv hluav taws xob loj, thiab muaj kev cuam tshuam ntau dua rau huab cua.
6. Kev lag luam tshuab
Graphite yog dav siv nyob rau hauv zus tau tej cov automotive nres linings thiab lwm yam Cheebtsam raws li zoo raws li high-temperature lubricants nyob rau hauv lub mechanical kev lag luam; Tom qab graphite tau ua tiav rau hauv colloidal graphite thiab fluorofossil number case (CF, GF), feem ntau yog siv los ua cov roj nplua nyeem hauv kev lag luam xws li dav hlau, nkoj, tsheb ciav hlau, tsheb thiab lwm yam khoom siv ceev ceev.
