| Abstract: | The influence factors when the biruea was oxygenated by chlorine to obtain small particle AC blowing agent were studied. Results show that the recovery of AC blowing agent increased 5%~8%, the decomposition gas of AC blowing agent increased 10~18 mL with the addtion of a little urea at 35~45°C, particle size 9 μm was obtained. |
