Lub luag haujlwm ntawm graphite pwm hauv brazing

Cov pwm graphite ua lub luag haujlwm tseem ceeb hauv kev sib txhuam, feem ntau suav nrog cov hauv qab no:

• Kho thiab tso rau qhov chaw kom ntseeg tau tias qhov vuam tswj tau qhov chaw ruaj khov thaum lub sijhawm ua haujlwm brazing, tiv thaiv nws kom tsis txhob txav mus los yog deforming, yog li ua kom ntseeg tau qhov tseeb thiab zoo ntawm qhov vuam.
  Kev hloov pauv cua sov thiab kev tswj qhov kub Vim tias graphite muaj cov thermal conductivity zoo, nws tuaj yeem hloov pauv cua sov sai thiab sib npaug, uas pab tswj kev faib tawm qhov kub thaum lub sijhawm brazing, yog li cov khoom siv brazing tuaj yeem yaj tag nrho thiab sau qhov weld kom ua tiav kev sib txuas zoo.
  Tsim ib daim duab thiab cov qauv tshwj xeeb Nws tuaj yeem tsim ua ib daim duab thiab cov qauv tshwj xeeb raws li qhov xav tau los pab tsim ib qho kev sib txuas vuam thiab cov duab vuam uas ua tau raws li qhov yuav tsum tau ua.
  Kev tiv thaiv zoo Muab kev tiv thaiv rau qhov vuam thiab txo qhov cuam tshuam thiab kev cuam tshuam ntawm ib puag ncig sab nraud rau cov txheej txheem brazing, xws li tiv thaiv kev oxidation.

Cov pwm graphite muaj ntau qhov zoo rau kev sib tsoo:

• Kev ua tau zoo heev ntawm cov cua sov. Muaj peev xwm hloov pauv cua sov sai sai, ua rau cov khoom siv brazing yaj sib npaug, txhim kho kev ua haujlwm zoo thiab zoo ntawm kev sib txuas. Kev tiv taus kub zoo. Muaj peev xwm nyob ruaj khov hauv qhov chaw brazing kub, tsis yooj yim rau deform lossis puas tsuaj.
  Kev ruaj khov tshuaj lom neeg siab Nws tsis yooj yim rau kev cuam tshuam tshuaj lom neeg nrog cov khoom siv brazing thiab weldment, ua kom ntseeg tau tias qhov huv si thiab ruaj khov ntawm cov txheej txheem vuam.
  Tus nqi qis dua Piv nrog rau lwm cov ntaub ntawv tiv taus kub siab, tus nqi ntawm cov pwm pob zeb yog qhov pheej yig, uas yog qhov zoo rau kev txo cov nqi tsim khoom.

Cov pwm graphite muaj feem cuam tshuam tseem ceeb rau qhov zoo ntawm kev sib txhuam:

• Cuam tshuam rau qhov kev sau ntawm qhov vuam
  Ib lub pwm graphite uas tsim nyog tuaj yeem ua kom cov khoom siv brazing puv tag nrho qhov vuam, tsim kom muaj qhov sib koom ua ke thiab sib zog, thiab txhim kho lub zog thiab kev sib khi ntawm qhov sib koom ua ke.
  Txheeb xyuas cov microstructure ntawm qhov sib koom ua ke
  Qhov kev ua tau zoo ntawm kev hloov pauv cua sov thiab cov duab ntawm cov pwm yuav cuam tshuam rau qhov kub thiab txias faib thaum lub sijhawm ua haujlwm brazing, yog li cuam tshuam rau microstructure thiab kev ua tau zoo ntawm qhov sib koom ua ke.
  Cuam tshuam rau qhov tseeb ntawm qhov vuam
  Qhov tseeb ntawm cov pwm muaj feem cuam tshuam ncaj qha rau qhov tseeb ntawm qhov vuam. Yog tias qhov tseeb ntawm cov pwm tsis siab, nws yuav ua rau qhov sib txawv ntawm qhov vuam thiab cuam tshuam rau nws txoj kev ua haujlwm.
