{{0 {}} Dab tsi yog cov khoom tseem ceeb ntawm txhuas kav dej?
Teb:
Aluminium kav yog cov kev nyiam rau lawvLub Zog Zog(Ceev ~ 2.7 g / cm³),Corrosion Kuj(Ntuj oxide txheej), thiabthermal conductivity(~ 237 w / minc k) {{{. Cov ntaub ntawv tsis zoo thiab ua kom zoo nkauj thiab rov xyaw}} (anodizing / hmoov txheej) tuaj yeem txhim kho durability .
2. Yuav ua li cas los xaiv txoj cai txhuas yeeb nkab taub thiab phab ntsa thickness?
Teb:
Kev Xaiv Nyob Ntawm:
Siab Xav Tau: Thicker phab ntsa (e {.}}}}}}} {) rau cov tshuab siab siab.
Ntsaws Cov Kabmob Xav Tau: Lub diam hlau loj dua (ntau dua los yog sib npaug rau 2 ") rau cov qauv kev pab txhawb .
Dej ntws: Sab hauv Dia cuam tshuam nrog tus nqi Flow (Hazen-Williams sib npaug) .
Piv txwv li: 1 lub sijhawm 40 yeeb nkab (0 {}}} psi 1200 psi. Nco ntsoov hla-kos nrog ASME B36.10M qauv.
3. Dab tsi yog cov qauv fabrication txheej txheem rau txhuas kav?
Teb:
Kev yeem: Biltse rhuab mus rau 800℃f thiab yuam los ntawm kev tuag rau cov proflex {}}
Vuam: Tig / Mig Vuam (ER4043 muab tub ua ke) rau pob qij txha; yuav tsum muaj Argon Shielding .
Dabtsi yog khoov: Dabtsi yog khoov (min radius (min vojvoog=3 x strike inch) zam annealing.
Ntaub: CNC LATHES LAUM / Flange kav dej nrog ± 0 . 00} 005 kev thev taus.
Post-pab ntaub, kev nyuaj siab nyem (ntawm 650℃f) tiv thaiv kev tawg.
{{0 {}} Cas ua li cas txhuas yeeb nkab piv rau cov hlau thiab tooj liab kav?
Teb:
| Ntiag tug | Tooj dawb | Hlau | Tooj liab |
|---|---|---|---|
| Qho hnyav | Lub teeb rau (30% hlau) | Hnyav | Tswj kav |
| Kev ua cev tub | Zoo tshaj | Nquag muaj xeb | Zoo (Tarnishes) |
| Tus nqi | 2.50-2.50-5.00 / LB | 0.50-0.50-1.50 / lb | 3.80-3.80-4.50 / lb |
| Thermal condition . | 237 W/m·K | 50 W/m·K | 401 W/m·K |
Aluminium kev txawj rau hauv qhov hnyav-rhiab thiab corrosive ib puag ncig, thaum lub taub hau haum rau dej cawv .
5. Niaj hnub no txoj kev ua haujlwm txuas ntxiv Aluminium Yeeb Nkab Nyiaj Lifespan?
Teb:
Ntxuav: Siv cov tshuaj ntxuav ph-nruab nrab kom tsis txhob oxide txheej kev puas tsuaj .
Kev kuaj xyuas: Khij rau pitting / Galvanic corrosion biannually (tshwj xeeb tshaj yog nyob ze cov hlau tsis sib xws) .
Kev povhwm: Siv cov nqi hloov dua tshiab txheej txheem hauv qab dej raug ua rau .
Chaw ntim khoom: Khaws sab hauv tsev lossis hauv qab UV-resistant npog kom tiv thaiv oxidation .
Lifespan feem ntau tau tshaj 25 xyoos nrog kev kho kom zoo.
