Thermogravimetric Analysis and Pyrolysis Kinetics Models of Waste Printed Circuit Board
摘要
Abstract
The pyrolysis characteristics of waste FR4 type printed circuit board (PCB) was studied by thermogravimetric (TG) analysis method. The TG and differential thermogravimetry (DTG) curves of the waste PCB at different heating rate and their changing rules were explored. The activation energy (E) of the pyrolysis reaction was solved exactly by Starink method. The mechanism function and pre-exponential factor (A) were obtained by Malek method. The research results show that; The TG and DTG curves of waste FR4 type PCB move to the high-temperature zone progressively with the increase of heating rate; The initial pyrolysis temperature, the temperature corresponding to the maximum weight loss rate and the terminated pyrolysis temperature also increase with it; The E and A of the waste PCB are 105.75 kJ/mol and 7. 89 x 108 min-1 respectively.关键词
