采用相同工艺参数,分别通分过理论计算和实验分析获得了发泡时间与发泡温度对泡沫铝气泡半径的影响规律。随着发泡时间从36 s延长至72 s,理论计算的气泡半径值从3.05 mm增大至6.11mm;而实验获得的气泡半径值则从1.62 mm增大到5.35 mm,且增大的趋势明显减缓。当发泡温度从953 K升高至993 K时,理论计算的气泡半径从2.25 mm增大到2.88 mm;实验获得的气泡半径值则从3.45 mm增大到5.03 mm,且增大的趋势也明显减缓,理论计算值约为实验获得值的1/2。
Using the same process parameters, respectively, through the theoretical calculation and experimental analysis were obtained by the foaming time and foaming temperature on the foam aluminum bubble radius rule. With the extension of the blowing time from 36 s to 72 s, the theoretical bubble radius increased from 3.05 mm to 6.11 mm, while the experimental bubble radius increased from 1.62 mm to 5.35 mm, and the trend of increasing Obviously slow down. The calculated bubble radius increased from 2.25 mm to 2.88 mm when the foaming temperature increased from 953 K to 993 K. The experimental bubble radius increased from 3.45 mm to 5.03 mm, Significantly slowed down, the theoretical value is about 1/2 of the experimentally obtained value.
