Cov txheej txheem kev npaj ntawm kub-nias graphite yog tsuas yog ua kom sov graphite hais los yog graphite chips mus rau qhov kub thiab txias, thiab ces compress lawv mus rau hauv tej ntaub ntawv nrog ib tug tej yam ceev. Muaj ntau txoj hauv kev los npaj cov graphite kub, xws li isothermal hot-pressing, non-isothermal hot-pressing, ceev kub nias, plasma kub nias, thiab lwm yam.
Cov khoom ntawm graphite kub nias yog nyob rau hauv ntau hom, feem ntau suav nrog phaj, thaiv, ntawv, sawb, hmoov, thiab lwm yam. Ntawm lawv, phaj thiab thaiv yog ob hom kev siv ntau tshaj plaws, uas yog siv dav hauv cov khoom siv hluav taws xob, hluav taws xob cua sov. , lub tshuab nqus tsev vacuum, aerospace, high-temperature structural parts, tshuaj reactors thiab lwm yam teb.
Kub-pressed graphite muaj cov khoom zoo hauv qab no:
Zoo conductivity: kub-pressed graphite muaj zoo conductivity, ntau tshaj 10 npaug ntawm cov graphite zoo tib yam, yog li nws yog dav siv los ua cov khoom siv electrode.
Cov thermal conductivity zoo heev: kub nias graphite muaj thermal conductivity zoo heev, thiab cov thermal conductivity tuaj yeem ncav cuag ntau tshaj 2000W / m • K. Yog li ntawd, kub nias graphite yog dav siv nyob rau hauv hluav taws xob cua sov, lub tshuab nqus tsev vacuum furnaces, high-temperature heat exchangers thiab lwm yam. teb.
Kev ruaj ntseg tshuaj zoo: kub-nias graphite kuj muaj kev ruaj ntseg zoo nyob rau hauv qhov kub thiab txias ib puag ncig corrosion, thiab tsis cuam tshuam rau corrosion thiab oxidation.
Cov khoom siv zoo heev: kub nias graphite yog cov khoom siv muaj zog nrog zoo heev compression, khoov thiab tawg tsis kam.
Kev ua haujlwm zoo: cov graphite kub xovxwm muaj kev ua haujlwm zoo, thiab tuaj yeem txiav, drilled, tig, milled thiab lwm yam kev txiav raws li kev xav tau sib txawv.
Nyob rau hauv ib lo lus, kub-nias graphite yog ib yam ntawm high-purity graphite khoom nrog zoo heev kev ua tau zoo thiab muaj ib tug dav daim ntawv thov kev cia siab. Nws tuaj yeem tsis tsuas yog ua tau raws li cov kev xav tau ntawm cov teb sib txawv, tab sis kuj tuaj yeem kho ntau lawm raws li cov neeg siv khoom xav tau kom tau raws li cov neeg siv khoom sib txawv ntawm daim ntawv thov.
