Research on Storage Life of Silicon Rubber O-ring in Different Temperature and Humidity Condition

摘要:

通过对硅橡胶P6144密封圈的加速老化试验,建立了该密封圈材料在贮存温度下的压缩永久变形和时间的关系,预测了25℃、35℃、45℃、55℃、65℃和75℃温度条件下硅橡胶P6144密封材料的贮存寿命,研究了温度对硅橡胶密封圈贮存寿命的影响规律。

Abstract:

The compression ratio equation was given with respect to storage temperature and time, and the storage life of P6144 was also estimated in different temperature i.e 25℃,35℃,45℃,55℃,65℃,75℃,etc in the acceleration aging tests of rubber silicon P6144. Finally, the effects regulation of temperature factors on the reliability of storage life of rubber silicon P6144 were studied in this paper.
