Brazing
Brazing yog kev sib koom ua ke ntawm cov hlau siv cov khoom siv molten, uas nyob rau hauv cov ntaub ntawv txias ua ib qho kev sib koom ua ke.
Cov khoom siv hlau melting kub yog siab tshaj 450 degree, tab sis hauv qab lub melting point ntawm cov hlau.
Nws ua haujlwm li cas?
Brazing sib koom ua ke lub hauv paus hlau los ntawm kev tsim ib tug metallurgical daim ntawv cog lus ntawm cov muab tub lim hlau thiab lub hauv paus hlau.
Thaum molten, cov hlau muab tub lim yog kos rau hauv kev sib koom ua ke los ntawm kev ua haujlwm capillary.
Yuav ua li cas koj muab muab tub lim hlau rau 100's ntawm kev sib koom ua ke ib txhij?

Aluminium oxide
Cov yam ntxwv ntawm aluminium oxide:
Hardness tseem ceeb tshaj 400Mpa
Siab tiv taus tshuaj
Cov oxide cuam tshuam nrog brazing
Aluminium tshuav ntau ntawm nws cov khoom kom muaj zog heev adherent oxide zaj duab xis ntawm qhov chaw.
Cov oxide no yuav tsum tau muab tshem tawm lossis tawg yog tias muaj kev sib koom ua ke.
Muaj ntau txoj hauv kev ua tiav qhov no.
Kev sib piv ntawm cov txheej txheem brazing:
CAB | Nqus brazing | Cua rauv brazing | |
Cua sov | Radiation/Convection | Hluav taws xob | quab yuam convection |
Kev siv flux | Yog lawm | TSIS MUAJ | TSIS MUAJ |
Qhov ntau ntawm flux | <5g/㎡ | - | 30~50g/m³ |
Kev kho mob ua ntej braze | Kev xav tau nruab nrab | Kev xav tau siab | Kev xav tau nruab nrab |
Post braze kev kho mob | TSIS MUAJ | TSIS MUAJ | Yog lawm |
Cov dej khib nyiab | TSIS MUAJ | Yog lawm | |
Atmospheric emissions | TSIS MUAJ | TSIS MUAJ | TSIS MUAJ |
Cov txheej txheem txuas ntxiv | Yog lawm | TSIS MUAJ | Yog lawm |

Kev siv nyiaj | 80 | 100 | 100 |
CAB rauv brazing txheej txheem ib ntus
Cov txheej txheem CAB yog nyob ntawm: Kev sib hloov hluav taws xob tsim hluav taws xob, kev ntxuav tu, Flux daim ntawv thov txheej txheem.
CAB furnace braze cycle
Cov xwm txheej txiav txim siab CAB ntau lawm ua tiav lossis tsis ua tiav
1. Cov khoom zoo haum (qhov sib txawv 0.1 txog 0.15mm)
2. Txaus kom muaj nuj nqis ntawm cov khoom siv hlau
3. Uniformity ntawm flux txheej
4. Kev sib cuam tshuam ntawm flux thiab alloying ntsiab
5. Rauv tej yam kev mob (kub lub sij hawm profile, kub uniformity, cua sov cua sov)
Cim npe nrov: Nqus Brazing txheej txheem, Tuam Tshoj, lwm tus neeg, manufacturers, hoobkas, customized, dawb qauv, ua nyob rau hauv Suav teb
