Taw qhia rau RFMISO cov txheej txheem tsim khoom-nqus brazing

1. Txoj Cai:

Nqus brazing siv thermal zog los ua kom sov lub solder rau nws melting point thiab coats rau saum npoo ntawm cov hlau qhov chaw yuav tsum tau kev cob cog rua.Nyob rau hauv ib puag ncig lub tshuab nqus tsev, cov rhuab solder melts thiab nkag mus rau qhov chaw sib cuag ntawm cov hlau.Raws li qhov kub thiab txias, lub solder solidifies thiab tsim ib tug muaj zog kev twb kev txuas.Lub tshuab nqus tsev ib puag ncig pab txo qis cov pa oxygen thiab lwm yam impurities, yog li muab cov brazing zoo dua.

2. Cov khoom siv thiab cov txheej txheem:

Nqus brazing feem ntau yuav tsum tau siv lub tshuab nqus tsev vacuum los yog lub tshuab nqus tsev vacuum los muab cov cua sov tsim nyog thiab lub tshuab nqus tsev.Lub tshuab nqus tsev feem ntau muaj cov khoom siv xws li cov khoom cua sov, lub tshuab nqus tsev, lub tshuab nqus tsev, thiab lub tshuab ntsuas kub.Thaum ua lub tshuab nqus tsev brazing, cov khoom hlau yog thawj zaug ntxuav thiab npaj, ces coated nrog brazing muab tub lim hlau.Tom ntej no, cov khoom yog muab tso rau hauv lub tshuab nqus tsev vacuum thiab rhuab kom cov solder melts thiab nkag mus rau qhov chaw sib cuag.Thaum kawg, qhov kub thiab txias yog txo, lub solder solidifies thiab kev sib txuas yog tsim.

3. Solder:

Hauv lub tshuab nqus tsev brazing, xaiv txoj cai muab tub lim hlau yog qhov tseem ceeb kom tau txais kev sib txuas zoo.Kev xaiv ntawm solder nyob ntawm yam xws li cov ntaub ntawv hlau yuav tsum tau koom nrog, thov kev thov thiab kev ua haujlwm kub.Common solders muaj xws li nyiaj-raws li, kub-raws li, tooj liab-raws li, nickel-based thiab lwm yam alloys.Solder feem ntau yog siv nyob rau hauv daim ntawv ntawm hmoov, ribbon los yog txheej.

4. Kev siv thaj chaw:

Lub tshuab nqus tsev brazing tshuab tau siv dav hauv ntau qhov chaw.Nws yog feem ntau siv hauv aerospace, khoom siv hluav taws xob, khoom siv kho qhov muag, lub tshuab nqus tsev, sensors, khoom siv kho mob thiab lub zog.Lub tshuab nqus tsev brazing ua rau lub zog siab, siab nruj thiab kev ntseeg siab ntawm kev sib txuas ntawm qhov kub thiab txias tsis tshua muaj siab, ua rau nws tsim nyog rau cov ntawv thov uas xav tau kev sib txuas zoo.

5. Qhov zoo

Lub tshuab nqus tsev brazing tshuab muaj qhov zoo hauv qab no:

- High-Strength Connection: Nqus brazing ua kom muaj zog hlau sib txuas nrog lub zog siab thiab sealing.

- Kev ua haujlwm kub qis: Lub tshuab nqus tsev vacuum feem ntau ua rau qhov kub qis dua li lwm txoj hauv kev vuam, txo qhov kev pheej hmoo ntawm cov khoom deformation thiab cov cheeb tsam kub.

- Kev sib txuas zoo: Lub tshuab nqus tsev ib puag ncig pab txo qis cov pa oxygen thiab lwm yam impurities, muab kev sib txuas zoo dua.

Feem ntau hais lus, tshuab nqus tsev brazing tshuab yog ib txoj kev sib txuas uas muaj zog heev uas koom nrog cov khoom hlau ua ke hauv lub tshuab nqus tsev.Nws yog dav siv nyob rau hauv ntau qhov kev lag luam, muab kev sib txuas txhim khu kev qha thiab kev sib txuas zoo heev.
