Midabka Oxidation-ka Chromel A Nickel Chromium Strip ee Biraha Alxanka

Sharaxaad Gaaban:

Chromel A waa daawaha nikkel-chromium ee loo isticmaalo heerkulka ilaa 1200°C. Daawaha u adkaysta kulaylka waxaa lagu dabaqaa jawiga oksaydhka sida nitrogen, ammonia, jawiga aan degganayn ee ka kooban isku-dhafka sulfur iyo sulfur. Chromel A wuxuu leeyahay astaamo ka sarreeya oo u adkaysta kulaylka marka loo eego daawaha birta-aluminium.
