Sida loo sameeyo foornada muffle in ay sii socoto muddo dheer

foornada muffle waa qalab kuleyl caalami ah, marka loo eego muuqaalka iyo qaabka waxaa loo qaybin karaa foornada foornada foornada, foornada muffle tube. Sidee looga dhigaa inay sii jirto muddo dheer?

1. Si joogto ah u hubi in xadhkaha kulul ee qayb kasta oo ka mid ah foornada dabaysha ay dabacsan yihiin, haddii xidhiidhiyaha AC ay xaaladdoodu wanaagsan tahay iyo in kale, haddii ay jiraan wax cillado ah, waa in la hagaajiyaa waqtiga.

2. Qalabka waa in lagu dhejiyaa meel qalalan, hawo leh, meel gaas ah oo aan daxal lahayn, heerkulka deegaanka shaqadu waa 10-50 ℃, heerkulku maaha in ka badan 85%.

3. Foornada nooca silikoon carbide , haddii usha silikoon carbide la ogaado in ay waxyeello gaartay, waa in lagu beddelaa ul carbide silikoon oo cusub oo leh tilmaamo isku mid ah iyo qiimo iska caabin ah oo la mid ah. Markaad bedesho foornada muffle-ga, marka hore ka saar daboolka difaaca iyo ul silikoon carbide chuck ee labada daraf ee foornada muffle, ka dibna soo saar usha carbide silikoon ee dhaawacan. Maaddaama usha carbide ee silicon ay tahay mid jilicsan, ka taxaddar markaad rakibayso. Madaxa waa in la xiraa si xiriir wanaagsan loola sameeyo usha carbide silikoon. Haddii chuck si aad ah oksidized, waa in lagu beddelaa mid cusub. Farqiga u dhexeeya godadka dhejinta ee labada daraf ee ulaha carbide silikoon waa in lagu xannibaa xadhkaha asbestos-ka.

Heerkulka foornada barafku waa inuusan dhaafin heerkulka shaqada ee 1400 ℃. Usha carbide ee silikoon waxaa loo ogol yahay inay si joogto ah u shaqeyso 4 saacadood heerkulka ugu sarreeya.

Intaa waxaa dheer, walxaha kuleyliyeyaasha silikoon carbide waa unug kuleyl ah oo aan bir ahayn oo ka samaysan silikoon carbide oo ah alaabta ceeriin ee ugu weyn. Waxay leedahay sifooyin balaadhinta yar yar, aan qallafsaneyn, xasilloonida kiimikada xooggan, nolosha adeegga dheer, iyo rakibidda iyo dayactirka habboon. Culayska dusha sare ee usha silikoon carbide = awoodda la qiimeeyay / aagga dusha sare ee qaybta kuleylka (W/cm2)

Culayska dusha sare ee usha silikoon carbide ee foornada heerkulka sare ee foornada kuleylka ayaa xiriir weyn la leh dhererka nolosha adeegga. Sidaa darteed, waa in si adag loo xakameeyaa inta u dhaxaysa baaxadda culeyska la oggol yahay marka la tamarinayo oo la kululeeyo, lagana fogaado culeyska xad dhaafka ah.
