Silicon nitride ua ke nrog silicon carbide thermocouple tiv thaiv raj thiab nws daim ntawv thov

Kev taw qhia ntawm silicon nitride ua ke nrog silicon carbide thermocouple tiv thaiv raj thiab nws daim ntawv thov yog raws li nram no:
Silicon nitride bonded silicon carbide khoom yog ib yam tshiab ntawm cov khoom, nrog rau cov khoom tseem ceeb xws li silicon nitride bonded silicon carbide radiation tubes, silicon nitride bonded silicon carbide cib, silicon nitride bonded silicon carbide daim hlau, thiab lwm yam. Nws yog dav siv nyob rau hauv ntau yam industries xws li steel, non-ferrous hlau, tshuaj siv tsev, thiab muaj ntau yam zoo xws li kev txuag hluav taws xob, kev tiv thaiv ib puag ncig, kub tsis kam, thiab corrosion kuj.
1. Silicon nitride ua ke nrog cov khoom siv silicon carbide muaj kev ntxhib los mos, nrog Mohs hardness txog 9. Ntawm cov ntaub ntawv uas tsis yog xim hlau, nws belongs rau qeb hardness, thib ob tsuas yog pob zeb diamond.
2. Lub zog ntawm silicon nitride ua ke nrog cov khoom siv silicon carbide nyob rau hauv chav tsev kub yog siab, thiab lawv tuav yuav luag tib lub zog thiab hardness li ntawm chav tsev kub ntawm qhov kub ntawm 1200 txog 1400 degree. Nrog rau qhov sib txawv ntawm kev siv huab cua, qhov siab tshaj plaws kev nyab xeeb kev siv kub tuaj yeem ncav cuag 1650-1750 degree .
3. Lub coefficient ntawm thermal expansion yog me me. Piv nrog silicon carbide thiab lwm yam khoom, nws muaj thermal conductivity thiab tsis yooj yim los tsim thermal stress. Nws muaj qhov zoo thermal shock stability thiab kev pab lub neej ntev. Kev kub siab creep tsis kam, corrosion kuj, huab cua txias thiab kub tsis kam, oxidation kuj, yooj yim los ua cov khoom nrog siab qhov tseeb uas ua tau raws li qhov yuav tsum tau ua.
4. Cov khoom siv dav siv hauv ntau yam kev lag luam xws li hlau, cov hlau tsis muaj hlau, cov khoom siv hauv tsev, thiab lwm yam, txuag hluav taws xob, kev tiv thaiv ib puag ncig, thiab txo cov nqi.
Lub tuam txhab lees paub kev ua haujlwm ntawm ntau hom silicon nitride composite thiab silicon carbide thermocouple tiv thaiv cov raj txhua xyoo puag ncig, siv los tiv thaiv qhov ntsuas kub ntsuas thermocouples hauv xov xwm tshwj xeeb thiab kev ua haujlwm hnyav. Nws muaj cov yam ntxwv ntawm qhov kub thiab txias tsis kam, hnav tsis kam, corrosion kuj, thiab ua rau lub neej ntev ntawm cov thermocouple.
