Zirconia (YSZ) Qws lub tog raj kheej sib tsoo xov xwm
Piv nrog alumina pas nrig Yttria stabilized zirconia (YSZ YTZP) rods tuaj yeem tiv taus kub dua.Zirconia kuj muaj qhov zoo dua corrosion thiab hnav tsis kam.Raws li cov khoom siv refractory tsis tshua muaj siab, kev ua haujlwm kub ntawm zirconia rods yuav siab li 1900C thiab ruaj khov rau feem ntau ntawm cov tshuaj corrosive thiab.Zirconia crucibles kuj muab thermal thiab hluav taws xob conductivity tsawg heev amking nws zoo tagnrho rau daim ntaub ntawv yuav tsum tau hluav taws xob thiab thermal insulating.
Txawm li cas los xij, tsis zoo li boron nitride, Zirconia pas nrig tsis pom zoo kom siv los ua cov khoom siv raw rau kev ua haujlwm ntxiv, vim muaj qhov hnyav thiab hnav tsis kam.
Yiho YSZ Rods
Raws li tus neeg muag khoom loj ntawm kev cai ua ntej ceramic cov ntaub ntawv nyob rau sab hnub tuaj ntug dej hiav txwv teb chaws USA, QS Advanced Materials ua hauj lwm ze nrog manufacturers ntawm ceramic sintering thiab machining muaj peev xwm muab zoo stabilized zirconia cov khoom uas muaj nqi npaum.Peb tab tom muab zirconia crucibles thiab lwm yam ntaub ntawv yooj yim.Nrog cov khoom lag luam semi tiav, thiab cov khoom muaj peev xwm ua tau zoo, qhov zoo hauv lub sijhawm ua haujlwm thiab tus nqi raug muab.
Daim ntawv thov ntawm Yttria Stabilized Zirconia (YSZ, YTZP) qhov chaw
• Siv rau kev sib tsoo cov ntaub ntawv ceramics, cov khoom sib nqus thiab cov qauv organic
• Cov kabmob thiab lwm yam hnav tsis kam siv tshuab
• Cov twj tso kua mis tshwj xeeb

Ntim
Raws li cov khoom siv ceramic, cov khoom siv Zirconia tseem nkig, txawm hais tias YSZ hloov pauv qee yam.Peb cov zirconia rods feem ntau yog tuav hauv hnab yas los ntawm lub tshuab nqus tsev, thiab tiv thaiv nrog ua npuas ncauj hnyav.
