Effect of Shell Composition on Pyrolysis Kinetics Characteristics of Core-shell Structured Bamboo Plastic Composites
摘要
Abstract
This paper reported an investigation on pyrolysis characteristics of core-shell structured bamboo-plastic composites (BPC) prepared by a co-extrusion processing method.These BPC were constituted by a core layer of high-density polyethylene (PE-HD)/bamboo residue fiber composite and four types of shells including pristine PE-HD/bamboo pulp fiber composite,PE-HD/nano-CaCO3 compound and PE-HD/white mud composite.The pyrolysis characteristics of BPC were evaluated by thermogravimetric analysis at different heating rates,and their pyrolysis kinetics was analyzed by Coats-Redferm's and Flynn-Wall-Ozawa's models.The results indicated that the thermal stability of BPC was improved in the presence of PE-HD/nano-CaCO3 and PE-HD/white mud shells,however,the formation of PE-HD/bamboo pulp fiber shell exhibited few effects on their thermal stability.Moreover,the apparent activation energy of BPC presented a slight change with addition of 10 wt ％ bamboo pulp fiber,nano-CaCO3 and white mud into their shell.关键词
