供应换气老化试验箱

换气老化特点
本机专门针对橡胶、塑料 及各种绝缘材料之热老化性做测试,其性能与一般老化炉不同，本机之设计具备有:
a. 温度调节精度。
b. 温度分布均匀。
c. 开门后温度回升速率。
d. 试验槽内之风速及换气率。
e. 试验槽内之隔热密封。
f. 特殊换气率调整装置。
g. 依据测试标准:
  JIS K-7217, K-7623, K-6301, ASTM D-2436, D-573, UL-746B, IEC-540, BS-6746, 903, ISO/DIS 4577 
换气率测定方法
This method measures the air change rate of the std type oven as follows
N=3590 (X-Y)x2 / VxDx
T
N: number of changes of air per hour
X: Power consumption during air change (W)
Y: Power consumption during no air change (W)
V: total volume of oven (cm3)
D: Density of oven ambient air (g/cm3)
T: Temperature difference inside/outside oven (°C)
