Nyob rau hauv niaj hnub high-temperature kev lag luam,silicon carbide graphite crucibletau dhau los ua cov khoom siv tseem ceeb vim nws cov khoom siv thermal zoo, tshuaj tiv thaiv thiab lub zog siab, thiab yog siv dav hauv cov hlau smelting, iav manufacturing, kuaj kev tshawb fawb thiab lwm yam kev lag luam. Tsab ntawv xov xwm no yuav piav qhia txog cov yam ntxwv tshwj xeeb, daim ntawv thov Scope thiab kev loj hlob yav tom ntej ntawm silicon carbide graphite crucibles.
Cov yam ntxwv ntawm silicon carbide graphite crucible
Kev sib xyaw ntawm silicon carbide (SiC) thiab graphite muab lub crucible zoo heev ntawm ob qho khoom siv. Qhov kev sib xyaw ua ke no muab silicon carbide graphite crucibles cov txiaj ntsig tseem ceeb hauv qab no:
Kev kub siab ua haujlwm zoo: Silicon carbide graphite crucible tuaj yeem ua haujlwm ruaj khov ntawm qhov kub siab tshaj 1600 ° C yam tsis muaj melting lossis deformation.
Ua haujlwm zoo thermal conductivity: Lub thermal conductivity yog siab dua li cov khoom siv ceramic, kom ntseeg tau tias qhov sib txawv ntawm qhov kub thiab txias nyob rau hauv crucible thiab txhim kho cua sov efficiency.
Muaj zog tshuaj tiv thaiv corrosion: Nws tuaj yeem tiv thaiv corrosion ntawm ntau yam tshuaj reagents thiab txuas nws lub neej kev pab cuam.
Lub zog zoo txhua yam: Kev sib xyaw ua ke ntawm silicon carbide hardness thiab lub zog ntawm graphite, nws tuaj yeem tuav cov khoom zoo txawm tias nyob rau hauv qhov kub thiab txias.
Cov thermal shock kuj zoo heev: Lawv tsis yooj yim rau tawg thaum lub sij hawm cua sov los yog txias txheej txheem, ua rau lawv zoo tagnrho rau cov cua kub ceev los yog txias txheej txheem.
Cov chaw thov
Silicon carbide graphite crucibles ua tau zoo hauv ntau cov ntawv thov kub, suav nrog:
Hlau smelting: Vim nws zoo heev thermal conductivity thiab corrosion kuj, nws yog dav siv nyob rau hauv lub smelting thiab refining txheej txheem ntawm txhuas, tooj liab, kub thiab lwm yam hlau.
Kev tsim iav: Muab qhov chaw ruaj khov kub-kub thaum lub sij hawm cov txheej txheem iav melting kom ntseeg tau tias cov iav melting sib xws thiab tsim.
Kev tshawb fawb hauv chav kuaj: Cov thawv ntim khoom siv feem ntau siv hauv cov ntaub ntawv tshawb fawb thiab kev sim ntsuas kub kom tswj tau qhov kub thiab txias.
Kev lag luam tshuaj: siv nyob rau hauv high-kub cov tshuaj tiv thaiv cov hlab ntsha thiab cov hlab ntsha los tuav cov tshuaj corrosive thiab high-temperature reactants.
Kev txhim kho yav tom ntej
Nrog rau kev nce qib ntawm kev siv thev naus laus zis thiab kev xav tau ntau ntxiv hauv kev lag luam kub kub, silicon carbide graphite crucibles muaj cov ntawv thov dav dav. Kev tshawb nrhiav thiab kev txhim kho yav tom ntej yuav tsom mus rau cov hauv qab no:
Cov Khoom Siv Ua Haujlwm Zoo: Nanotechnology thiab cov ntaub ntawv sib xyaw tshawb fawb ntxiv txhim kho lub crucible qhov kev ua haujlwm thermal thiab lub zog txhua yam.
Kev tswj hwm tus nqi: Txhim kho cov txheej txheem tsim khoom, txo cov nqi tsim khoom, ua silicon carbide graphite crucibles ntau tus nqi, thiab nthuav dav lawv daim ntawv thov.
Kev txhim kho ib puag ncig: Tsim cov khoom siv rov ua dua tshiab rau ib puag ncig kom txo tau qhov cuam tshuam rau ib puag ncig thiab txhawb kev txhim kho ntsuab-kub technology.
nyob rau hauv xaus
Raws li cov khoom siv ua haujlwm siab, silicon carbide graphite crucible plays lub luag haujlwm tseem ceeb hauv kev lag luam kub niaj hnub nrog nws qhov kub thiab txias tsis kam, thermal conductivity, corrosion kuj thiab lwm yam ntxwv. Nrog kev nce qib ntawm kev siv thev naus laus zis thiab kev nthuav dav ntawm daim ntawv thov teb, silicon carbide graphite crucibles yuav ua lub luag haujlwm tseem ceeb hauv kev siv tshuab kub kub yav tom ntej thiab txhawb kev tsim khoom zoo dua qub thiab zoo ib puag ncig hauv ntau yam lag luam.
Los ntawm kev nkag siab tob thiab kev siv ntawm silicon carbide graphite crucibles, ntau dua kev ua tiav tuaj yeem ua tiav hauv kev ua haujlwm kub, tsav tsheb kev nce qib thiab kev txhim kho kev lag luam.
