Lub luag haujlwm ntawm graphite pwm hauv Brazing

Graphite pwm ua lub luag haujlwm tseem ceeb hauv Brazing, feem ntau yog suav nrog cov hauv qab no:

• Tsau thiab muab tso rau kom ntseeg tau tias cov weldment tswj txoj hauj lwm ruaj khov thaum lub sij hawm txav chaw lossis deforming, yog li ua kom raug thiab zoo ntawm kev vuam.
  Thaum tshav kub hloov thiab ntsuas kub vim tias cov txheej txheem hluav taws xob kub thiab txias, nws tuaj yeem hloov kho kom sai thiab ua kom tiav Weld kom ua tiav qhov kev sib txuas tau zoo.
  Ua ib daim duab tshwj xeeb thiab cov qauv uas nws tuaj yeem tsim los ua cov duab thiab kev tsim nyog los pab ua cov kab sib koom ua ke thiab cov qauv weldment uas ua tau raws li cov cai.
  Cov nyhuv tiv thaiv muab qee qhov kev tiv thaiv rau kev cuam tshuam rau kev cuam tshuam thiab cuam tshuam ntawm cov txheej txheem sab nraud ntawm cov txheej txheem brrazing, xws li tiv thaiv oxidation.

Graphite pwm muaj ntau cov txiaj ntsig tseem ceeb rau Brazing:

• Zoo heev thermal condactivity tuaj yeem hloov cua kub sai li sai tau tuaj yeem txhim kho qhov kev ua tau zoo thiab zoo rau kev ua kom yooj yim los yog kev puas tsuaj.
  Siab tshuaj lom neeg stability nws tsis yooj yim kom hnov ​​cov tshuaj nrog cov khoom siv brazing thiab weldment, kom muaj kev ruaj ntseg ntawm cov txheej txheem vuam.
  Tus nqi qis nrog lwm cov khoom kub tiv taus, tus nqi ntawm cov pwm pob zeb yog cov nyiaj txiag sib xws, uas yog qhov tseem ceeb los txo cov nqi ntau lawm.

Graphite pwm muaj qhov cuam tshuam tseem ceeb ntawm kev ua tau zoo:

• Cuam tshuam rau cov ntawv ua tiav ntawm Weld
  Ib qho kev haum graphite pwm tuaj yeem ua kom paub tseeb tias cov khoom lag luam brazing puv rau tus weld, sib sau ua ke thiab txhim kho lub zog thiab sib xyaw ua ke.
  Txiav txim siab microstructure ntawm kev sib koom tes
  Lub tshav kub hloov pauv kev ua tau zoo thiab cov pwm ntawm cov pwm yuav cuam tshuam rau qhov ntsuas kub thiab txias thaum lub sij hawm brazing, yog li cuam tshuam rau microstructure thiab kev ua haujlwm ntawm kev sib koom ua ke.
  Cuam tshuam rau qhov tseeb ntawm weldment
  Qhov tseeb ntawm cov pwm yog cuam tshuam ncaj qha ntsig txog qhov tseeb ntawm kev nyab xeeb. Yog tias cov pwm qhov tseeb tsis yog siab, nws yuav ua rau muaj kev sib txawv ntawm kev muab weldment thiab cuam tshuam nws qhov kev ua tau zoo.
