SISIC(RBSIC)ROLLERS
Daim ntawv thov thaj chaw: cov menyuam kiln lithium roj teeb zoo thiab tsis zoo hloov pauv cov ntaub ntawv, cov khoom sib nqus, cov khoom siv hluav taws xob ceramic, cov khoom siv hluav taws xob niaj hnub, cov khoom siv refractory, xws li hloov cov txheej txheem sintering, yog cov khoom siv tseem ceeb tshaj plaws hauv cov menyuam kiln, hauv qhov cub ua lub luag haujlwm nqa. thiab hloov cov khoom. Cov tshuaj tiv thaiv zoo heev ntawm silicon carbide cov menyuam bar ua rau nws ua haujlwm ntev nyob rau hauv qhov chaw muaj zog corrosive ib puag ncig ntawm lithium kiln thiab muaj lub neej ua haujlwm ntev.
Hauj lwm lawm
Silicon carbide yob bar yog ib hom khoom siv ceramic siab heev uas yog siv rau hauv cov ntawv thov kub xws li cov rauv thiab cov kilns. Cov khoom muaj cov khoom zoo heev xws li tsis kam hnav, corrosion, thiab thermal shock, ua rau nws yog qhov kev xaiv zoo tshaj plaws rau kev lag luam.
Cov yob tuav yog tsim los ntawm silicon carbide hmoov, uas yog consolidated los ntawm sintering ntawm kub kub. Cov txheej txheem no ua rau cov khoom siv ntom ntom thiab homogenous nrog cov khoom zoo heev. Cov yob tuav yog ces machined rau qhov xav tau cov duab thiab loj kom haum rau daim ntawv thov.
Silicon carbide yob bar yog siv dav hauv kev tsim cov hlau thiab txhuas, kev ua tshuaj lom neeg, thiab kev siv tsheb xws li nres nres. Lawv muab cov thermal conductivity siab thiab qis thermal expansion, uas ua rau lawv tiv taus thermal shock thiab thermal cycling. Lawv kuj muaj cov coefficient tsawg ntawm kev sib txhuam, uas ua rau lawv zoo tagnrho rau siv nyob rau hauv daim ntawv thov uas lubrication nyuaj.
Ib qho txiaj ntsig tseem ceeb ntawm silicon carbide yob bar yog lawv lub neej ua haujlwm ntev. Lawv tuaj yeem kav ntev txog 10 npaug ntev dua li cov khoom siv xws li steel lossis cam khwb cia hlau, uas txhais tau hais tias tus nqi qis dua thiab qis dua rau cov khoom siv. Lawv kuj yog ib puag ncig tus phooj ywg vim lawv tuaj yeem siv tau yooj yim dua.
