湿热状态对有机玻璃性能的影响

Influence of Wet and Hot Atmosphere on the Properties of Plexiglass

考察了湿热状态下有机玻璃吸水率、拉伸强度、冲击强度的变化。结果表明:随着有机玻璃在水中存放时间的增加,有机玻璃的吸水率增加,拉伸强度和冲击强度下降;随着有机玻璃对水分的吸收逐渐饱和,三项性能的变化幅度逐渐减小。

The variation of water absorption, tensile strength and impact strength of plexiglass under humid and hot environment are studied. Results show that the water absorption increases, the tensile strength and impact strength decrease of plexi-glass with the increase of soaking time of plexi-glass in water. With the gradual saturation of moisture absorption of plexi-glass, the variation of the 3 indicators is gradually reduced.
