Cov thermal conductivity thiab hluav taws xob conductivity ntawm graphite rods yog siab heev, thiab lawv cov hluav taws xob conductivity yog 4 zaug siab dua cov hlau tsis muaj steel, 2 zaug siab dua carbon steel, thiab 100 lub sij hawm siab tshaj ntawm cov non-metals. Nws cov thermal conductivity tsis tsuas yog ntau tshaj cov hlau, hlau, txhuas thiab lwm yam khoom siv hlau, tab sis kuj txo qis nrog qhov kub thiab txias, uas txawv ntawm cov khoom siv hlau zoo tib yam. Thaum kub heev, graphite tuaj yeem ua kub. Yog li ntawd, thermal rwb thaiv tsev cov khoom ntawm graphite yog heev txhim khu kev qha ntawm ultra-siab kub.
Graphite rods feem ntau yog siv rau electrothermal extraction nyob rau hauv high kub lub tshuab nqus tsev furnaces. Qhov kub ua haujlwm siab dua tuaj yeem ncav cuag 3000℃, thiab nws yooj yim rau oxidized ntawm qhov kub thiab txias. Tsuas yog lub tshuab nqus tsev, lawv tsuas yog siv tau rau hauv nruab nrab lossis txo qis cua.
Vim nws cov khoom zoo heev, graphite tau siv dav hauv ntau qhov chaw thiab tuaj yeem siv los ua cov khoom siv refractory.
Cov khoom lag luam graphite tuav cov khoom qub ntawm cov graphite flake thiab muaj zog ntawm tus kheej lubricating zog. Graphite hmoov yog tus cwj pwm los ntawm lub zog siab, acid tsis kam, corrosion kuj, siab thiab kub tsis kam.
Graphite muaj cov tshuaj zoo ruaj khov ntawm chav tsev kub thiab tsis corroded los ntawm cov kua qaub uas muaj zog, lub hauv paus muaj zog thiab cov kuab tshuaj organic, yog li txawm tias nws siv rau lub sijhawm ntev, qhov poob ntawm cov khoom graphite tsawg heev, tsuav yog nws tau ntxuav kom huv. , nws yog tib yam li tshiab.
