Raws li cov pob zeb hauv av uas muaj cov pa roj carbon, graphite muaj feem cuam tshuam nrog peb lub neej, thiab cov neeg ib txwm siv cov cwj mem, cov pas nrig roj teeb qhuav thiab lwm yam. Txawm li cas los xij, graphite muaj kev siv tseem ceeb hauv kev lag luam tub rog, cov ntaub ntawv refractory, kev lag luam metallurgical, kev lag luam tshuaj lom neeg thiab lwm yam.
Graphite muaj ob qho tib si hlau thiab tsis yog hlau yam ntxwv: graphite ua tus neeg coj ua zoo ntawm thermoelectricity qhia txog cov yam ntxwv hlau; Cov yam ntxwv tsis yog hlau yog qhov kub thiab txias tsis kam, thermal stability siab, tshuaj inertness thiab lubricity, thiab nws siv kuj dav heev.
Daim ntawv thov tseem ceeb
1, cov ntaub ntawv refractory
Hauv kev lag luam metallurgical, nws yog siv los ua cov khoom siv refractory thiab tus neeg sawv cev tiv thaiv rau cov hlau ingot. Vim tias graphite thiab nws cov khoom muaj cov yam ntxwv ntawm kev tiv taus kub thiab lub zog siab, nws yog siv hauv kev lag luam metallurgical los ua graphite crucible, steel furnace lining, tiv thaiv slag thiab txuas ntxiv casting.
2, kev lag luam hlau casting
Hlau thiab casting: Graphite yog siv los ua carburizer hauv kev lag luam steelmaking.
Hauv kev ua casting, graphite siv rau kev ua casting, sanding, molding cov ntaub ntawv: vim yog qhov coefficient me me ntawm thermal expansion ntawm graphite, kev siv graphite ua casting xim, qhov loj ntawm casting yog qhov tseeb, qhov chaw du, cov kab nrib pleb thiab qhov pores casting raug txo, thiab cov txiaj ntsig siab. Tsis tas li ntawd, graphite siv rau hauv kev tsim cov hmoov metallurgy, superhard alloys; Kev tsim cov khoom carbon.
3. Kev lag luam tshuaj lom neeg
Graphite muaj kev ruaj khov tshuaj zoo. Cov graphite ua tshwj xeeb muaj cov yam ntxwv ntawm kev tiv taus corrosion, thermal conductivity zoo thiab permeability qis. Kev siv graphite los ua cov kav dej graphite tuaj yeem ua kom muaj kev tshuaj lom neeg ib txwm muaj thiab ua tau raws li qhov xav tau ntawm kev tsim cov tshuaj huv siab.
4, Kev lag luam hluav taws xob thiab hluav taws xob
Siv rau hauv kev tsim cov hmoov graphite electrode me me, txhuam, roj teeb, roj teeb lithium, roj teeb zoo electrode conductive khoom siv, anode phaj, hluav taws xob pas nrig, carbon tube, graphite gasket, xov tooj qhov chaw, rectifier zoo electrode, electromagnetic shielding conductive plastics, heat 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 ua cathode ntawm electrolytic cells rau electrolysis ntawm cov hlau xws li magnesium thiab txhuas.
Tam sim no, cov kua roj fluorine fossil (CF, GF) siv dav hauv cov khoom siv roj teeb muaj zog, tshwj xeeb tshaj yog CF0.5-0.99 fluorine fossil inks, uas tsim nyog dua rau kev ua cov khoom siv anode rau cov roj teeb muaj zog, thiab cov roj teeb me me.
5. Lub zog atomic, aerospace thiab kev tiv thaiv kev lag luam
Graphite muaj qhov chaw yaj siab, ruaj khov, tiv taus corrosion thiab tiv taus A-rays thiab neutron deceleration kev ua tau zoo, siv hauv kev lag luam nuclear ntawm graphite cov ntaub ntawv hu ua nuclear graphite. Muaj neutron moderators rau atomic reactors, reflectors, kub cylinder number rau isotope ntau lawm, spherical graphite rau kub roj txias reactors, nuclear reactor thermal Cheebtsam sealing gaskets thiab bulk blocks.
Graphite siv rau hauv cov thermal reactors thiab, vam tias, fusion reactors, qhov twg nws tuaj yeem siv ua tus neutron moderator hauv thaj chaw roj, ua cov khoom siv reflector nyob ib puag ncig thaj chaw roj, thiab ua cov khoom siv hauv lub hauv paus.
Tsis tas li ntawd xwb, graphite kuj siv rau hauv kev tsim cov khoom siv foob pob hluav taws ntev lossis cov khoom siv foob pob hluav taws hauv chaw, cov khoom siv aerospace, cov khoom siv rwb thaiv tsev kub thiab cov khoom siv tiv thaiv hluav taws xob, kev tsim cov roj av khov kho lub cav foob pob hluav taws lub qhov ntswg, thiab lwm yam, siv rau hauv kev tsim cov txhuam aviation, thiab cov khoom siv spacecraft DC motors thiab cov khoom siv aerospace, cov teeb liab sib txuas xov tooj cua satellite thiab cov khoom siv conductive; Hauv kev lag luam tiv thaiv, nws tuaj yeem siv los tsim cov bearings rau cov nkoj me me tshiab, tsim cov graphite purity siab rau kev tiv thaiv lub tebchaws, cov foob pob graphite, lub qhov ntswg rau cov dav hlau stealth thiab cov foob pob hluav taws. Tshwj xeeb, cov foob pob graphite tuaj yeem ua rau lub chaw hloov pauv thiab lwm yam khoom siv hluav taws xob loj tsis ua haujlwm, thiab muaj kev cuam tshuam ntau dua rau huab cua.
6. Kev lag luam tshuab
Graphite siv dav hauv kev tsim cov khoom siv nres tsheb thiab lwm yam khoom siv nrog rau cov roj nplua nyeem kub siab hauv kev lag luam tshuab; Tom qab graphite ua tiav rau hauv colloidal graphite thiab fluorofossil ink (CF, GF), nws feem ntau siv ua cov roj nplua nyeem khov kho hauv kev lag luam tshuab xws li dav hlau, nkoj, tsheb ciav hlau, tsheb thiab lwm yam tshuab khiav ceev.
