Non-isothermal Kinetics of Low Temperature Thermal Debinding Stearic Acid

Non-isothermal kinetics of low tempersture thernal debinding stearic acid in PIM is studied by TG.The kinetics parameters are determined by differential and integral method.In the polypropylene based greenware,the most possible debinding kinetics equation is -ln(1-a)=A exp(-E/RT)t^1/4.The burnout rate is controlled by the diffusion of stearic acid in polypropylene.
