Graphite purity siab yog hais txog cov pa roj carbon uas muaj nyob hauv graphite. 99.99%, siv dav hauv kev lag luam hlau ntawm cov khoom siv refractory thiab txheej txheem zoo, cov khoom siv hluav taws kub hauv tub rog, cov hlau lead hauv kev lag luam sib zog, cov txhuam carbon hauv kev lag luam hluav taws xob, cov electrode hauv kev lag luam roj teeb, cov tshuaj ntxiv catalyst hauv kev lag luam chiv, thiab lwm yam.
Cov khoom graphite vim nws cov qauv tshwj xeeb, nrog rau kev tiv taus kub siab, kev tiv taus thermal shock, kev ua hluav taws xob, lubricity, tshuaj lom neeg ruaj khov thiab plasticity thiab ntau lwm yam ntxwv, tau yog ib qho tseem ceeb hauv kev lag luam thiab kev lag luam niaj hnub thiab cov thev naus laus zis siab, tshiab thiab ntse, cov khoom graphite, xws li graphite rings, graphite ships tau siv dav, cov kws tshaj lij thoob ntiaj teb tau kwv yees tias "xyoo pua 20th yog xyoo pua ntawm silicon," Lub xyoo pua 21st yuav yog xyoo pua ntawm carbon.
Raws li ib qho khoom siv tseem ceeb uas tsis yog hlau, kev lag luam graphite yuav raug siv los tswj kev nkag mus. Nrog rau kev siv lub kaw lus nkag mus, graphite, cov khoom graphite, yuav dhau los ua lwm yam tom qab cov khoom siv av tsawg, tshuaj fluorine, tshuaj phosphorus, thiab cov tuam txhab ua lag luam hauv daim teb no yuav nkag mus rau theem tshiab ntawm kev txhim kho.
Cov txheej txheem graphite:
Los ntawm kev xaiv cov khoom siv graphite siab purity los tsim cov khoom siv tib yam, tom qab ntawd yuav tsum tau zom cov khoom siv raw no ua hmoov zoo, thiab tom qab ntawd siv cov thev naus laus zis tshwj xeeb isostatic. Yuav kom ua tiav qhov kev qhia tshwj xeeb, lub voj voog ci thiab impregnation yuav tsum tau ua ntau zaus, thiab lub voj voog graphitization yuav tsum ntev dua. Tam sim no, cov ntaub ntawv graphite uas peb feem ntau pom hauv kev ua lag luam yog graphite siab purity, molded graphite, isostatic graphite, EDM graphite thiab lwm yam. Thaum kawg, cov ntaub ntawv graphite raug txiav rau hauv cov khoom graphite xws li graphite pwm, graphite bearings, graphite nkoj thiab lwm yam khoom graphite uas feem ntau siv hauv kev lag luam los ntawm kev ua haujlwm.
