Graphite Pobzeb: Qhov muaj txiaj ntsig thiab ib puag ncig cov khoom siv hauv tsev
Graphite vuas yog qhov tshiab ntawm cov khoom tsim tsev uas tau ua tiav los ntawm kev tsim kho vim nws qhov kev ua tau zoo thiab ib puag ncig. Kab lus no yuav muab cov lus qhia ntxaws ntxaws rau cov yam ntxwv yooj yim, kev siv cov xwm txheej, thiab yav tom ntej kev txhim kho cov qauv ntawm cov vuas graphite graphite.
1, tus yam ntxwv ntawm graphite viles
Lub ntsiab tivthaiv ntawm graphite vuas yog ntuj graphite, uas tau ua tshwj xeeb ua thiab ua tiav. Nws muaj ntau yam ntxwv tshwj xeeb, xws li lub zog siab, siab ua haujlwm, thiab cov kev sib txhuam, tuaj yeem tiv thaiv kev nyuaj siab thiab tsis yooj yim. Nyob rau tib lub sijhawm, nws tseem muaj qhov zoo thermal conductivity, uas muaj peev xwm hloov pauv thiab tawg tshav kub, tiv thaiv cov khoom puas tsuaj los ntawm qhov kub hloov. Ntxiv rau, graphite vuas muaj cov tshuaj lom neeg muaj zog ruaj khov thiab tsis yooj yim cuam tshuam los ntawm ib puag ncig thiab huab cua, uas tuaj yeem tswj lawv qhov kev ua tau ruaj khov rau lub sijhawm ntev.
Cov txheej txheem tsim khoom ntawm graphite viles
Cov txheej txheem tsim khoom ntawm graphite vuas yog qhov yooj yim kuj yooj yim, feem ntau yog suav nrog cov kauj ruam xws li cov khoom siv raw khoom, kev sib xyaw, thiab kho kom nto. Firstly, nws yog ib qho tsim nyog los xaiv cov khoom zoo ntuj zoo li cov khoom siv raw, thiab kev tshuaj ntsuam kom tau txais graphite me me. Tom qab ntawd, cov lus graphite tau sib xyaw nrog cov nqi uas tsim nyog sib xyaw thiab ua rau cov txheej txheem xws li nias thiab Sintering los ua cov kab vuas graphite nrog qee yam duab thiab kev ua tau zoo. Thaum lub sijhawm Sintering cov txheej txheem, nws yog ib qho tsim nyog los tswj qhov kub thiab sijhawm los txo cov porosity hauv cov graphite vile, txhim kho nws lub zog thiab thermal conductivity. Thaum kawg, kev kho deg thiab lwm yam kev ua los txhim kho lub corrosion tsis kam thiab zoo nkauj ntawm graphite vuas.
3, Daim Ntawv Qhia Txog Cov Lus Qhia ntawm Graphite Vuas
Vim nws cov khoom tau zoo heev, cov qauv vuas muaj ntau cov kev siv. Hauv kev ua teb ntawm architecture, graphite vuas tuaj yeem siv rau rwb thaiv tsev rwb thaiv tsev thiab kho kom zoo nkauj, phab ntsa, thiab lwm qhov chaw. Nws tuaj yeem txo cov qhov kub hloov pauv hauv cov tsev, txhim kho cov kev ua tiav rwb thaiv tsev thiab txuag hluav taws xob ntawm cov tsev.
Cov khoom ntawm Graphite Vuas
Graphite Pobzeb yog ib yam khoom siv yog suav nrog ntawm ntuj ci graphite, uas yog tsim los ntawm kev kho mob tshwj xeeb thiab kev tsim khoom. Nws muaj ntau yam muaj cov khoom muaj nqis, suav nrog:
- Muaj zog: Graphite vuas tuaj yeem tiv taus cov kev nyuaj siab zoo thiab kev sib txhuam, thiab tsis yooj yim deformed lossis puas.
- Siab thermal conductivity: v graphite vuas muaj zoo thermal conductivity, uas tuaj yeem hloov kho cua sov, tiv thaiv cov khoom siv kev puas tsuaj los ntawm qhov kub hloov.
- Corrosion Kuj: Graphite Vuas muaj cov tshuaj lom neeg ruaj khov, tsis yooj yim cuam tshuam los ntawm ib puag ncig thiab huab cua, thiab tuaj yeem tswj lawv qhov kev ua tau ruaj khov rau lub sijhawm ntev.
- Anti laus: Graphite cov pobzeb tsis yooj yim cuam tshuam los ntawm lub sijhawm thiab ib puag ncig cov yam, thiab lub neej ntev kev pabcuam.
- Kev kub siab kuj: lub ntsiab lus melting ntawm graphite yog qhov siab li 3850 ± 50 ℃, thiab lub qhov cub npau yog 4250 ℃. Txawm tias nyob rau hauv ultra-high kub arc hlawv, qhov hnyav poob yog me me, thiab lub zog nce nrog qhov kub. Ntawm 2000 ℃, lub zog ntawm graphite yog ob npaug.
- Conductivity thiab thermal conductivity: kev ua haujlwm ntawm graphite yog 100 npaug tshaj li qhov dav dav tshaj li ntawm cov ntaub ntawv hlau xws li hlau, hlau, thiab txhuas, thiab ua. Txawm li cas los xij, lub thermal conductivity coeffient tsis tshua muaj nrog kev nce kub. Thaum kawg kub heev, graphite tuaj yeem dhau los ua cov khoom siv rwb thaiv tsev.
- Lubricity: lubrication ua yeeb yam ntawm graphite nyob ntawm qhov loj me ntawm nplai. Qhov loj dua cov nplai, cov me me txhuam coefficient, thiab zoo dua lubrication kev ua tau zoo.
- Tshuaj lom neeg ruaj khov: Graphite muaj cov tshuaj muaj peev xwm nyob rau chav nyob zoo, thiab tuaj yeem tiv taus cov kua qaub, alkali, thiab organic kuab corrosion.
Qhov saum npoo ntawm qhov chaw ze yog them nrog graphite vuas uas muab thermal rwb thaiv tsev thiab kev tiv thaiv. Qhov no yog vim muaj lub siab tau loj, thiab cov tshuaj rwb thaiv tsev ntawm graphite, uas tuaj yeem muab cov khoom siv thermal thiab kev tiv thaiv thaum lub chaw kaw huab cua thiab ua kom muaj kub.
