| Abstract: |
| Objective To study the classification method of atmospheric environment severity for the application of typical polymer materials. Method The natural environment test of polystyrene was carried out in ten typical environment areas of China. The change rules and variation of surface and mechanical properties of polystyrene were compared and analyzed. The parameters of atmospheric environmental severity were determined, and the atmospheric environmental severity was classified according to the parameters evaluated. Results The yellow index of polystyrene surface increased linearly with time and the laws were consistent. The constant in the aging model can be taken as the performance parameters for evaluation of the atmospheric environment severity. Solar radiation and high temperature and humidity were the main environmental factors affecting the degradation of polystyrene. Conclusion The performance of polystyrene can be used as the evaluation parameter of atmospheric environment severity, and atmospheric environment severity of China can be divided into six levels |
