Khoom Txheej Txheem
High-thermal-conductivity ntshiab huv hlau (ntau dua los yog sib npaug ntawm kev sib tw kub thiab oxi}}}
Vim li cas cov thermal conductivity teeb meem hauv cov hlau ntshiab
Thermal ua kev ntsuas cov khoom muaj peev xwm ua kom muaj cua sov (w / min k) . Cov cuab yeej ntshiab los ntawm:
- Kev Siv Hluav Taws Xob Hluav Taws Xob: Cov Hluav Taws Xob Nruab Nrab Ua kom sov nrog qhov tsawg tshaj plaws tawg vim tias ultralow impurities (c tsawg dua lossis sib npaug lossis sib npaug nrog 0.002%)
- crystalline simplicity: BCC cov qauv tsim qauv ua rau cov suab-ua haujlwm kub nrog kev cuam tshuam kub tsawg
- Tsis kam lees tswj: Vocial-dawb tsim cov minimizes kub ntws teeb
Yuav ua li cas ntshiab hlau outperforms cov ntaub ntawv cov ntaub ntawv

Cov tswv yim tseem ceeb:
Cov hlau ntshiab muab cov kev pom kev zoo rau cov ntawv thov kev xav tau yooj yim, thiab thermal nyob rau hauv rawivity tab sis tsis ua tiav nyob rau hauv high-temp / corrosive ib puag ncig; Stainless hlau withstls kub tab sis "cuab" thermal zog .
Cov Kev Tshwj Xeeb:
Precision-Engineered Thermal Kev Ua Haujlwm
Peb cov qauv xim ntshiab rau DT4 / DT4A Cov Qauv (GB, Astm sib npaug), nrog cov khoom kom zoo ntawm:
- Kub Rolling / Txias Dragacation: lis cov khaub noom ua kom zoo rau isotropic kub txaus
- Annaling ntawm 470 degree: Kev ntxhov siab nyem kom tshem tawm cov pa hluav taws xob tsis sib haum
- Pickling & Oiling: nto passivation tiv thaiv oxidation
Kws ua choj cov lus
Q: Yog txheej tsim nyog rau corrosion tsis kam?
A: Rau cov chaw hnyav:
Phosphating: Rau cov kua qaub (e {{{0} g ., tshuaj lom neeg nroj tsuag)
Aluminizing: For >600℃oxidation tsis kam
Q: Tau thermal conductivity yog kev qhia txog kev txhim kho li cas?
A: Yog {{{.} txias dov tau tuaj yeem ntxias 12% anisotropy:
Cim npe nrov: High-thermal-conductivity ntshiab huv hlau, Tuam Tshoj siab-thermal-conductived ntshiab cov hlau tuam tsev, lwm tus neeg, Hoobkas
