Melting,Crystallization and Thermal Degradation of Fly Ash/Lldpe Blends

Abstract:

Fly ash/LLDPE composite material was obtained by using the molten blending. The melting, crystallization and thermal degradation of fly ash/LLDPE blends were investigated. The results indicate that the addition of fly ash increases the molten peak of blends, which shows that fly ash has the function to prevent heat transfer. The addition of the powder of fly ash has prevented the regular spread of LLDPE molecue and has impact on the regular spread when the segmer crystallizes, spreads and moves, which slows LLDPE's crystallization rate, and has an inhibitory action to LLDPE crystalloid's growth; the starting degradation tempreture (T0, 5%weight loss ) of complex system is lower than that of pure LLDPE, but the tempreture at maximum egradation rate increases with the quantity of fly ash increasing.
