1. Positionnement core produit
Graphite macceer bu njëkk ngir brik yu karbon magnesium, macceer bu njëkk la buñ jagleel defar brik yu karbon magnesium yu am doole. Dafa sukkandikoo ci graphite flake bu sell lool wala graphite artifisiyel bu baax, dafay jaar ci anam yu melni setal physique, gëdd grade, ak dindi mbalit. Dafa am stabilite bu baax ci tàngoor wu kawe, te mën na ànd ak agrégat magnesie, muy liggéey bu am solo ngir gëna mëna xeex corrosion, gëna mëna xeex choc thermique, ak doole mekanik bu brik carbone magnesium.
