Graphite yog ib qho ntawm cov pa roj carbon, ib qho siv lead ua hloov pauv ntawm cov nplaim hluav taws xob, cov nplais hlau thiab cov nplaim hluavtaws.Qhov feem ntau yog xim dub, xim zoo nkauj, ua kom lub ntsej muag sov. organic acids.Used raws li cov tshuaj tiv thaiv kab mob thiab cov khoom siv lubricating, ua crucible, hluav taws xob, roj teeb qhuav, xaum xim. graphite emulsion, nthuav graphite, av nplaum graphite thiab conductive graphite hmoov, thiab lwm yam.
1. kub tsis kam tiv taus: cov ntsiab lus melting ntawm graphite yog 3850 ± 50 ℃, txawm tias tom qab kub kub heev kub hnyiab, qhov hnyav poob me me, cov cua sov nthuav dav coefficient me me.Lub zog ntawm graphite nce nrog qhov kub nce . Ntawm 2000 ℃, lub zog ntawm graphite ob npaug.
2. conductive, thermal conductivity: conductivity ntawm graphite yog ib puas npaug ntau dua li cov hlau tsis yog hlau.Qhov thermal conductivity ntawm hlau, hlau, txhuas thiab lwm yam khoom siv hlau.Thermal conductivity txo nrog qhov nce ntawm qhov kub, txawm tias kub siab, graphite rau rwb thaiv tsev;
3. lubricity: lub lubrication kev ua tau zoo ntawm graphite nyob ntawm qhov loj ntawm graphite flake, flake, txhuam coefficient yog me dua, lub lubrication kev ua tau zoo dua;
4. tshuaj lom neeg ruaj khov: graphite ntawm chav sov muaj cov tshuaj zoo ruaj khov, tiv taus kua qaub, tiv taus alkali thiab ua kom cov organic hnyav tiv taus xeb;
5. plasticity: graphite toughness yog qhov zoo, tuaj yeem tsoo rau hauv daim ntawv nyias nyias;
6. thermal poob siab tsis kam: graphite ntawm chav sov thaum siv tuaj yeem tiv taus qhov hloov pauv ntawm qhov kub tsis muaj kev puas tsuaj, hloov pauv kub, qhov ntim ntawm graphite hloov me ntsis, yuav tsis tawg.
1. kev txheeb xyuas qhov muaj pes tsawg leeg: tsau cov pa, dej noo, tsis huv, thiab lwm yam;
2. Kev ntsuas lub cev muaj zog: tawv, tshauv, viscosity, fineness, particle loj, volatilization, qhov nqus tshwj xeeb, thaj chaw tshwj xeeb, qhov chaw yaj, thiab lwm yam.
3. kev ntsuas cov khoom siv dag zog: lub zog tensile, brittleness, khoov khoov, ntsuas tensile;
4. Tshuaj ntsuam kev ua haujlwm: dej tsis kam, ua haujlwm ntev, kua qaub thiab alkali tsis kam, tiv taus xeb, huab cua tsis kam, tiv tshav kub, thiab lwm yam
5. Lwm yam khoom ntsuas: hluav taws xob conductivity, thermal conductivity, lubrication, chemical stability, thermal shock resistance
