Cov txheej txheem los tsim cov duab impregnated
Impregnation yog ib qho kev xaiv theem ua los txhawm rau txhim kho cov khoom ntawm cov khoom kawg. Tars, Pitches, resins, molten hlau thiab lwm yam reagents tuaj yeem muab ntxiv rau cov duab ci (hauv cov ntawv tshwj xeeb graphite duab tuaj yeem raug impregnated) thiab lwm cov reagents yog siv los sau cov voids tsim hauv cov khoom siv carbonized. Soaking nrog kub thee tar suab nrog lossis tsis muaj lub tshuab nqus tsev thiab autoclaving yog siv. Ntau yam txheej txheem impregnating yog siv nyob ntawm cov khoom xws li tab sis batch lossis quasi-nruam kev ua haujlwm yog siv. Lub voj voog impregnation feem ntau yog preheating cov duab, impregnation thiab txias. Ib lub zog reactor kuj tseem siv tau. Cov electrodes uas yuav tsum tau impregnated tuaj yeem preheated los ntawm cov khib nyiab ntawm thermal oxidiser. Tsuas yog cov carbon tshwj xeeb yog impregnated nrog ntau yam hlau. Cov khoom ci los yog graphitised tej zaum yuav impregnated nrog lwm yam ntaub ntawv, xws li resins los yog hlau. Impregnation yog nqa tawm los ntawm soaking, qee zaum nyob rau hauv lub tshuab nqus tsev thiab qee zaum nyob rau hauv siab, autoclaves yog siv. Cheebtsam uas tau impregnated los yog bonded nrog coal tar suab yog rebaked. Yog hais tias resin bonding tau siv, lawv yuav kho tau.
Cov txheej txheem los tsim cov duab rebaked los ntawm impregnated duab
Ci thiab rov qab ci Re-baking tsuas yog siv rau cov duab impregnated. Cov duab ntsuab (lossis Impregnated shapes) yog rebaked ntawm qhov kub txog li 1300 ° C siv ntau lub cub tawg xws li qhov av, ib chav tsev, ntau lub chamber, annular thiab laub qws rauv nyob ntawm qhov loj thiab qhov nyuaj ntawm cov khoom. Kev ci tsis tu ncua kuj ua tiav. Cov kev ua haujlwm ntawm lub cub tawg zoo ib yam li cov uas siv rau electrode duab ci txheej txheem, tab sis cov
Lub qhov cub feem ntau me dua.
