复合NP阻燃剂处理杨木的热解特性与动力学分析
Pyrolysis characteristics and kinetics of poplar treated by compound N-P flame retardant.
摘要
Abstract
In order to study the flame retardant mechanism and pyrolysis characteristics of poplar treated by compound N-P flame retardant,we applied thermal analysis method to analyze the combustion performance of poplar treated by distilled water,Al-Si,N-P and N-P-Al-Si,numbered as A,B,C and D,respectively.Ozawa-Flynn-Wall and Coats-Redfern (modified) were used to calculate activation energy of flame retardant poplar.The results showed that A had only one pyrolysis process,with the activation energy value of this phase 65--70 kJ/mol.The pyrolysis process of flame retardant treated poplar could be divided into two stages.The main pyrolysis stage of D was between that of B and C.D had the lowest weight loss rate and least weight loss,and heat release rate of this treatment was also slow.There was a similar trend of weight loss of TG curves of D at different heating rates,and weight loss curves shifted to higher temperature section with the increasing heating rate.The activation energies of the first and second phase of D (120 and 240 kJ/mol) were higher than that of C (115 kJ/mol) ,indicating that the flame retardant efficiency was improved when Al-Si and N-P were blended.关键词
