Tsawg thermal conductivityrefractory bricksthiab nano thermal rwb thaiv tsev cov ntaub ntawv yog dav siv nyob rau hauv cement ntau lawm. Lawv ua lub luag haujlwm tseem ceeb hauv kev txhim kho kev tsim khoom, txo kev siv hluav taws xob, thiab txhim kho cov cuab yeej siv tau ntev. Cov hauv qab no yog cov ncauj lus kom ntxaws txog kev siv ob cov ntaub ntawv no hauv kev tsim cov cement:
1. Daim ntawv thov ntawm cov thermal conductivity tsawg refractory firebricks kom txo tau lub zog noj: nyob rau hauv cov cement ntau lawm, cov txheej txheem smelting yog ib feem nrog lub zog loj tshaj plaws. Tsawg thermal conductivity refractory hluav taws cib muaj cov thermal conductivity coefficient tsawg, uas tuaj yeem txo cov kev siv hluav taws xob hauv cov txheej txheem smelting. Thaum lub sij hawm smelting txheej txheem, high-temperature nplaim yuav tsum tau sinter cement raw cov ntaub ntawv. Cov nplaim hluav taws kub kub no yuav ua rau muaj hluav taws kub kub los ntawm phab ntsa ntawm lub cub tawg thiab lub cub tawg hauv qab, ua rau lub zog loj heev. Cov thermal conductivity tsawg ntawm cov thermal conductivity refractory cib tuaj yeem txo cov hluav taws xob kub kub los ntawm cov phab ntsa ntawm lub cub tawg thiab lub cub tawg hauv qab, yog li txo cov hluav taws xob poob. Txhim kho kev ua tau zoo ntawm refractory: Thaum lub sij hawm smelting txheej txheem, cov phab ntsa ntawm lub cub tawg thiab lub cub tawg hauv qab yuav tsum tau tiv thaiv cov nplaim hluav taws kub kub, yog li lawv yuav tsum muaj kev ua tau zoo dua refractory. Tsawg thermal conductivity refractory hluav taws cib tsis tsuas yog muaj cov thermal conductivity tsawg, tab sis kuj muaj kev ua haujlwm siab refractory, uas tuaj yeem tiv thaiv cov phab ntsa ntawm lub cub tawg thiab lub cub tawg hauv qab kom lawv tsis txhob raug puas tsuaj los ntawm kev kub hnyiab kub. Txhim kho thermal efficiency thiab thermal stability: Kev siv cov thermal conductivity tsawg refractory cib kuj tuaj yeem txhim kho cov thermal efficiency ntawm cov cement smelting. Yog hais tias lub thermal conductivity ntawm lub cub tawg phab ntsa thiab lub cub tawg hauv qab yog siab, nws yuav ua rau kub poob thiab txo thermal efficiency. Tsawg thermal conductivity refractories cib tuaj yeem txo cov thermal conductivity ntawm phab ntsa ntawm lub cub tawg thiab lub cub tawg hauv qab thiab txhim kho thermal efficiency. Tsis tas li ntawd, tsis tshua muaj thermal conductivity refractories cib kuj tuaj yeem txhim kho cov thermal stability ntawm lub cub tawg thiab txo qhov kub hloov pauv hauv qhov cub.
2. Daim ntawv thov ntawm nano thermal rwb thaiv tsev cov ntaub ntawv tseem ceeb txo cov melting kub: Nano thermal rwb thaiv tsev cov ntaub ntawv muaj thermal conductivity thiab muaj peev xwm tiv thaiv tau tshav kub hloov, yog li lawv muaj peev xwm zoo txo qhov poob ntawm tshav kub nyob rau hauv lub cub tawg, yog li txo cov melting kub. Txhim kho qhov cub kub kom ruaj khov: Cov ntaub ntawv nano thermal rwb thaiv tsev muaj kev ua haujlwm siab refractory thiab tuaj yeem tiv thaiv kev sib kis ntawm cov nplaim taws, yog li lawv tuaj yeem txhim kho qhov ruaj khov ntawm qhov kub thiab txias thiab zam qhov kub tsis ruaj khov los ntawm cov nplaim taws. Txo kev siv hluav taws xob: Txij li cov ntaub ntawv nano-cov rwb thaiv tsev tuaj yeem txo qhov kub ntawm qhov kub thiab txhim khu kev ruaj ntseg ntawm qhov cub kub, lawv tuaj yeem txo cov cua sov hauv lub cub tawg thiab txo lub zog noj. Kev siv cov ntaub ntawv nano-cov ntaub ntawv pov thawj hauv kev tsim cov cement tuaj yeem txo qhov kub poob ntawm lub tog raj kheej lub tog raj kheej, txo qhov kev ua haujlwm ntawm qhov cub, thiab ua tiav lub zog txuag thiab txo kev noj.
Tsawg thermal conductivity refractory bricks thiab nano-insulation cov ntaub ntawv muaj ib qho tseem ceeb daim ntawv thov nqi nyob rau hauv cov cement ntau lawm. Lawv tuaj yeem tsis tsuas yog txo qis kev siv hluav taws xob, txhim kho kev ua haujlwm ntawm refractory thiab thermal efficiency, thiab txhim khu kev ruaj ntseg thermal nyob rau hauv lub cub tawg, tab sis kuj tseem txhim kho kev ua tau zoo thiab zoo ntawm cov cement ntau lawm. Nrog rau kev nce qib ntawm kev siv thev naus laus zis thiab kev txhawb nqa tob tob ntawm daim ntawv thov, ob cov ntaub ntawv no yuav ua lub luag haujlwm tseem ceeb hauv kev tsim cov cement. Nyob rau hauv lub neej yav tom ntej, peb yuav tsum ntxiv dag zog rau kev tshawb fawb thiab kev loj hlob ntawm ob cov ntaub ntawv no los txhawb lawv cov kev siv dav thiab nruam innovation nyob rau hauv cov cement ntau lawm.
