Ordinary industrial-qib magnesia hmoov muaj cov seem carbonate, dawb ya raws thiab lwm yam ntxhia impurities uas decompose thiab volatilize nyob rau hauv qhov kub thiab txias tshaj 500 degree, yog li siab -purity siab- kub calcined magnesia ua tshwj xeeb sau raw khoom rau Inconel- sheath nrog thermocoännered ultra-siab- kub tshwj xeeb kub khiav thiab lub zog tshiab hauv tsev PEEK cov khoom siv molding. Tom qab siab -kub calcination kev kho mob siab tshaj 1600℃hauv kev cob qhia, impurity muaj pes tsawg leeg nyob rau hauv raw magnesia yog tag nrho decomposed thiab tshem tawm, tshuav siab -purity magnesium oxide nta ruaj khov tshuaj inertness thiab zoo heev - kub rwb thaiv tsev kev ua tau zoo yam tsis muaj roj los nag lossis ntim shrinkage.} ntev ntev {{12} ua haujlwm. Ordinary uncalcined low-purity magnesia tso tawm ntau cov dej vapor thiab acidic decomposed gas tom qab tau rhuab mus rau qhov kub siab, sab hauv generated roj siab expands tsis tu ncua thiab lov compact rwb thaiv tsev qauv ntawm thermocouple, corrosive decomposed roj erodes core platinum-rhodium los yog npib tsib xee} cov hlau tsis ua hauj lwm sab hauv thiab nickel los ntawm{16. ntsuas drift nyob rau hauv luv luv ntau lawm voj voog.
Dhau li ntawm cov thermal stability zoo, calcined magnesia tswj cov rwb thaiv tsev zoo ib yam nyob rau hauv qhov dav ntawm qhov kub thiab txias ntawm chav tsev kub mus txog 600 degree, kom ntseeg tau tias ruaj khov teeb liab kis tau tus mob noble hlau S/R- hom thermocouple siv rau ultra- siab- kub khiav. Nws thawj qhov tsis zoo yog nyob rau hauv cov khoom siv raw khoom ntau dua thiab cov txheej txheem calcination ua haujlwm sib piv nrog cov khoom lag luam magnesia, uas ua kom tiav cov thermocouple muag cov nqi nce ntxiv. Yog li kev tswj xyuas kev ua haujlwm nruj me ntsis txawv cov qib raw khoom raws li cov neeg ua haujlwm kub kub ua haujlwm, tsuas yog teeb tsa calcined magnesia puv thermocouple rau PEEK, PI thiab siab - kub fluoroplastic molding kub khiav saum toj 480℃qhov kub thiab txias, xaiv kev lag luam zoo tib yam magnesia specification rau cov pa roj carbon monoxide {8} PP, tsis tsim nyog tshaj -spec procurement cost pov tseg.
Kev tshuaj ntsuam xyuas zoo tau teeb tsa siab -kub calcination txheeb xyuas cov khoom rau siab -kawg kev txiav txim siab thermocouple, sampling hmoov kom ua siab - ntsuas kub ntsuas kub thiab saib seb puas muaj roj tsis haum, tshem tawm cov khoom tsis zoo sib xyaw nrog uncalcined miscellaneous magnesia ua ntej installation.
