Corundum tubeyog ib yam khoom siab -kub resistant ceramics feem ntau yog tsim los ntawm siab- purity alumina (Al ₂ O ∝ Ntau dua lossis sib npaug li 99%), dav siv hauv cov xwm txheej xws li hlau thiab tsis yog- qauv ntsuas hlau thiab siab - kub ua haujlwm. Nws cov yam ntxwv muaj xws li ntev -lub sij hawm kub tsis kam ntawm 1600℃(luv-lub sij hawm 1800 degree), tsis kam ua kom txias thiab cua sov, tsis kam mus rau tshuaj corrosion, thiab porosity tsawg (%). Cov khoom lag luam npog cov cuab yeej siv khoom siv xws li cov raj rauv taws, cov raj ruaj khov, cov raj tiv thaiv thermocouple, thiab lwm yam.
Khoom Khoom
Lub raj corundum yog tsim los ntawm kev txhaj tshuaj molding tshuab thiab muaj cov yam ntxwv hauv qab no:
1. Thermal stability: tuaj yeem tiv taus ntev - siv sijhawm ntawm 1600℃(txog 1800℃rau luv- siv sijhawm)
2. Mechanical properties: flexural strength>350MPa, compressive strength>12000MPa
3. Corrosion kuj: tuaj yeem tiv taus acid, alkali thiab molten hlau corrosion
Daim ntawv thov teb
1. Cov khoom siv hauv chav kuaj: cov khoom tseem ceeb ntawm lub raj rauv, lub tshuab nqus tsev vacuum, thiab cua tshuab cua sov
2. Kev soj ntsuam kev lag luam: Kev ntsuam xyuas hlau rau kev txiav txim siab carbon thiab sulfur ntawm cov kav dej
3. Instrument manufacturing: thermocouple tiv thaiv / rwb thaiv tsev raj, siab kub resistant ntsuas Cheebtsam
