主 题：Composite insulator mullite pyrolysis recycling silicone rubber sintering
摘 要：Composite insulators have been widely used in transmission *** being removed from transmission lines,their housing silicone material cannot degrade *** tackle this problem,this paper proposes an effective method to recycle waste insulators by pyrolysis to obtain mullite(3Al_(2)O_(3)·2SiO_(2))with high purity and compact *** recycling process studied will not generate toxic *** thermal degradation process of housing material is investigated by analyzing its degradation products including the gas and residues in *** experimental results indicate that the colorant agent Fe2O3 inside the housing material is beneficial for the generation of mullite by decreasing the temperature of ***,since the transitional alumina generated by the dehydration of aluminum hydroxide(ATH)has a smaller diameter and can better dissolute into the silica phases,ATH is a better choice as the additional aluminum *** comparing the components,structure,and particle size of grains formed at different calcination temperatures,the proposed pyrolysis temperatures of the two stages are 1400◦C and 1600◦C,respectively.
