| Φ300–330 | 300–600 | 21–51 | Cov tshuab hnyav, cov khoom siv hluav taws xob |
Nta:
Kev tiv thaiv muaj zog heev rau kev poob siab thermal: nrog rau qhov coefficient qis heev ntawm kev nthuav dav thermal, nws tuaj yeem tiv taus qhov kev hloov pauv kub hnyav thaum lub sijhawm rov tsim dua thiab tsis yooj yim tawg.
Tus nqi qis thiab thev naus laus zis paub tab: 30% ~ 50% pheej yig dua li SiC, nws yog qhov kev daws teeb meem thawj zaug rau cov tsheb thauj neeg thiab cov tsheb thauj khoom me.
Kev sib xyaw ua ke: seamless, qis rov qab siab, yooj yim installation.
Haum rau:
Tsheb SUV diesel hauv tsev
Cov tsheb thauj khoom me me thiab cov tsheb npav hauv nroog (nres nres ntau zaus, ua haujlwm tsis hnyav)
Nyiaj tsawg, nrhiav kev siv nyiaj kom zoo
Nta:
1. Kev tiv taus kub siab heev:txog li 2700 ℃, tsis ntshai hlawv lossis yaj.
2. Kev ua kom sov sai heev:Cov cua sov rov ua dua tshiab yog sib npaug zos, nrog rau kev ua haujlwm rov ua dua tshiab siab thiab tsawg dua qhov kev pheej hmoo ntawm kev khiav tawm thermal.
3. Muaj zog heev, lub neej ua haujlwm ntev:hnav-resistant, corrosion-resistant, tuaj yeem siv tau 5-8 xyoo nyob rau hauv cov xwm txheej ua haujlwm hnyav.
4. Cov pa roj carbon ntau:tuaj yeem khaws cov pa roj carbon ntau dua, nrog rau lub sijhawm rov ua dua tshiab ntev, tsim nyog rau lub nra hnyav mus sij hawm ntev.
Haum rau:
Cov tsheb thauj khoom hnyav, cov tshuab siv hauv kev tsim kho, cov tsheb khawb av (kev thauj khoom hnyav mus sij hawm ntev, kub heev).
Cov tshuab tsis yog txoj kev, cov khoom siv hluav taws xob.
Cov xwm txheej ua haujlwm hnyav nrog kev rov ua dua tshiab thiab yooj yim tshauv thaiv.
