换气老化试验箱／橡胶老化箱／上海换气老化箱报价

"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)
