Nickel Ua npuas ncauj yog cov khoom siv hlau ntxig nrog ib peb - qhov seem mesh qauv

Nickel ua npuas ncauj yog cov khoom siv hlau uas muaj ntxig hlau nrog ib peb - tus qauv mesh. Vim tias nws qhov kev siab ntsws siab, thaj chaw loj heev, zoo thermal conductivity, tshwj xeeb tshaj yog nyob rau hauv kev hloov pauv thaum tshav kub kub thiab txhim kho kev ua haujlwm zoo. Hauv qab no yog nws cov ntaub ntawv thov tseem ceeb thiab cov txiaj ntsig kev ua haujlwm:
I. Core Apperararios

- nws cov hlau pob txha taub hau (Nickel Thermal txoj kev pab sov, tuaj yeem txhim kho cov khoom siv kub ceev ntawm cov khoom siv sib xyaw (tuaj yeem nce los ntawm 3-10 zaug.
{{0- Peb {{1} desensional network qauv kev sib cuag ntawm molten ntsev hloov.

2. Txhawb rau cov duab sib xyaw ua ke PARase hloov Thermal cia khoom (PCMS)
{{0- Teeb meem: Soli {1} kua theem hloov pauv (xws li high} kub ntim, uas yuav tsum tau ntim thiab qeeb qeeb hloov.
{{0- Kev daws: Infiltrate Molten ntsev rau hauv cov pores ntawm lub qhov hws nickel ua ib daim duab sib xyaw ua ke PCM:
- Tus qauv siv Nickel ntawm Nickel ua npuas ncauj ntseej cov kua txiv molenen ntsev los ntawm cov capillary quab yuam kom tiv thaiv tsis taus.
- Cov hlau pob txha taub hau hloov pauv ntawm cua sov mus rau sab hauv ntawm molten ntsev thiab luv ntawm theem hloov pauv.
3. Sau nruab nrab hauv Molten ntsev tso tsheb hlau luam / tshav kub sib pauv
-}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}} Cov miv nyob hauv cov tso tsheb kub lossis hluav taws kub tuaj yeem:
-} Nce} Ua kom muaj kev kub ntxhov, rhuav tshem cov kab ua kom zoo nkauj txheej, thiab txhim kho cov kev hloov pauv kub confefficient.
-} ntev ntev dua cov molten ntsev ntws ntws thiab txhim kho lub tshav kub sib pauv.

2. Cov ncauj lus kom ntxaws ntawm cov ntsiab lus zoo
Cov yam ntxwv tau mus rau Molten ntsev Thermal Cia Khoom
Siab porosity (85% -9%) tso cai rau ntau npaum li cas ntawm molten ntsev kom raug impregnated thaum tswj cov txheej txheem ruaj khov. Lub cheeb tsam muaj thaj chaw loj me me ua ntu zus thaj tsam ntawm Molten ntsev thiab tshav kub hloov nruab nrab, thiab txhim kho kev hloov cua sov.
Zoo heev thermal conductivity sai sai hloov chaw kub mus rau sab hauv ntawm molten ntsev, thiab nce tshav kub tso / tso tawm.
High tshuab zog nrog kev kub siab - kub molten ntsev yaig thiab thermal kev ntxhov siab kom tsis txhob muaj cov qauv sib tsoo.
High -} kub corrosion distance Nickel muaj qhov ruaj khov nyob hauv cov ntsev uas zoo nkauj (xws li nitrates thiab chlorides lub neej
(impurities xws li sulfates yuav tsum tau tswj).

III. Cov kev sib tw thiab daws cov tswv yim
1. Molten ntsev corrosion
{{0- kev pheej hmoo: nyob rau hauv ntev-}}} qhov kev kub siab (molten ntsev) yuav corrode lub npib tsib xee, ua rau muaj cov txheej txheem tsis muaj zog.
{{0 {}} Kev daws:
{{0- Xaiv high- cov ntsev) polar).
{{0- kev hloov kho deg (xws li txheej al₂o₃) los txhim kho corrosion tsis kam.
{{0- huab cua nickel alloy ua npuas ncauj (xws li ni-} cr) kom txhim kho corrosion.
2. Tus nqi tswj hwm
- Tus nqi Nickel Ua Npuas Ncauj yog qhov ua kom zoo dua (xws li siv nws tsuas yog hauv cov qauv sib pauv kub, lossis kev tsim qauv Gradient Composite).

3. Kev sib xyaw ua ke tsim
- Cov qauv pore (ppi tus nqi), sau tus nqi thiab kev ua npuas ncauj yuav tsum tau ua kom muaj kev sib luag ntawm lub siab poob thiab kub hloov tes hauj lwm zoo.

IV. Cov Ntaub Ntawv Thov Cov Ntaub Ntawv
- Hnub Ci Thermal Zog Lub Zog (CSP
-} Kev Siv Pov Tseg Yooj Yim: Siv Nickel Ua Npuas Ncauj / Molten FREECite PCM Cov Qauv Siv Kom Rov Qab Los-} kub kub tso pa tawm kub.
- nuclear lub zog: raws li cov cua sov hloov txhim kho kev txhim kho hauv Molten cov tshuaj ntsuab, txhim kho lub zog hloov ua haujlwm.

V. Kev Tsim Kho Yav Tom Ntej
1. Tsim cov txheej txheej npib tsib xee (xws li ni - AL₂O₃, ni-}} s corrosion tsis kam.
2. Gradient Pore Tus Qauv Qauv Tsim: Txhim kho lub pore loj faib rau cov kev hloov pauv kub txo qis.
3. Ua ke nrog nanofluids: Ntxiv nanoparticles (xws li al₂o₃ nanoparticles) rau cov ntsev ntau ntxiv rau kev hloov pauv ntawm cov neeg tawg nrog Nickel ua npuas ncauj.
