Graphite hmoov tuaj yeem siv los ua tus cwj mem, yog li vim li cas graphite hmoov tuaj yeem siv ua xaum? Koj puas paub? Nyeem nws nrog tus editor!
Ua ntej tshaj plaws, graphite hmoov yog mos thiab yooj yim los txiav, thiab graphite hmoov kuj yog lubricated thiab yooj yim sau; Raws li yog vim li cas 2B cwj mem yuav tsum tau siv nyob rau hauv kev xeem nkag mus kawm ntawv qib siab, nws cov conductivity yuav tsum tau siv. Thib ob, hais txog cov khoom siv tshuaj lom neeg, graphite hmoov yog tsim los ntawm C lub ntsiab lus, thiab cov khoom siv tshuaj lom neeg ntawm C yog qhov ruaj khov ntawm chav tsev kub, yog li siv graphite hmoov mem hluav los sau cov ntaub ntawv tuaj yeem txuag tau ntev.
Graphite hmoov muaj cov khoom tshwj xeeb hauv qab no vim nws cov qauv tshwj xeeb:
1) Kub-kub kuj: Graphite hmoov muaj ib tug melting point ntawm 3850 50 ℃ thiab ib tug boiling point ntawm 4250 ℃. Txawm hais tias nws raug kub hnyiab los ntawm ultra-siab kub arc, nws qhov hnyav poob thiab thermal expansion coefficient tsawg heev. Lub zog ntawm graphite hmoov nce nrog qhov nce ntawm qhov kub thiab txias, thiab lub zog ntawm graphite hmoov doubles ntawm 2000 ℃.
2) Conductivity thiab thermal conductivity: Lub conductivity ntawm graphite hmoov yog ib puas lub sij hawm siab tshaj ntawm cov nonmetallic ores. Thermal conductivity tshaj cov khoom hlau xws li hlau, hlau thiab txhuas. Cov thermal conductivity txo qis nrog qhov nce ntawm qhov kub thiab txias, thiab txawm tias qhov kub thiab txias, graphite hmoov ua ib qho insulator. Graphite hmoov tuaj yeem ua hluav taws xob vim tias txhua cov pa roj carbon atom hauv graphite hmoov tsuas yog tsim peb daim ntawv cog lus nrog lwm cov pa roj carbon atoms, thiab txhua cov pa roj carbon atom tseem khaws ib qho hluav taws xob dawb los hloov cov nqi.
3) Lubricity: Lub lubricating khoom ntawm graphite hmoov nyob ntawm qhov loj ntawm graphite hmoov nplai. Qhov loj ntawm cov nplai, qhov me me ntawm kev sib txhuam coefficient thiab qhov zoo dua cov cuab yeej lubricating.
4) Chemical stability: Graphite hmoov muaj tshuaj ruaj khov zoo ntawm chav tsev kub, thiab tuaj yeem tiv taus acid, alkali thiab organic hnyav corrosion.
5) Plasticity: Graphite hmoov muaj qhov zoo toughness thiab tuaj yeem ua hauv av nyias nyias.
6) Thermal shock resistance: Graphite hmoov tuaj yeem tiv taus qhov kev hloov pauv ntawm qhov kub thiab txias ntawm chav sov yam tsis muaj kev puas tsuaj. Thaum qhov kub hloov pauv sai sai, qhov ntim ntawm graphite hmoov tsis hloov ntau thiab tawg yuav tsis tshwm sim.
