| Abstract: |
| Objective To investagte the natrual aging properties of HNBR in typical areas of China.Methods Natrual aging experiments of HNBR sample were performed in Wanning, Mohe, Dunhuang, Banna and Jinan. Compression set was tested and the data were used to evaluate the effect of the different natural environment on the material.ResultsBased on the theory of atatistic analysis, compression set was selected as a parameter factor to establish the equation between the compression set and storage time at natual enviroment.Conclusion The storage time of HNBR as seaing metarials can be ascertained from2to6years in different areas using the relevant equation, which is most affected in Banna and minimal in Mohe. |
