PCB ga-abụrịrị ọkụ na-eguzogide ma ọ nweghị ike ire ọkụ n'otu ọnọdụ okpomọkụ, naanị iji mee ka ọ dị nro. A na-akpọ ebe okpomọkụ n'oge a iko mgbanwe okpomọkụ (TG point), nke metụtara nha nkwụsi ike nke PCB.
Gịnị bụ elu TG PCB na uru nke iji elu TG PCB?
Mgbe okpomọkụ nke elu TG PCB adahade ụfọdụ bụ, ndị mkpụrụ ga-agbanwe si "iko steeti" na " roba steeti", mgbe ahụ okpomọkụ n'oge a na-akpọ vitrification okpomọkụ (TG) nke osisi. N'ikwu ya n'ụzọ ọzọ, TG bụ okpomọkụ kachasị elu nke mkpụrụ osisi na-anọgide na-esi ike.
Kedu ụdị bọọdụ PCB nwere kpọmkwem?
