摘要
研究涤纶长丝/涤纶长丝-聚氨酯材质消防水带热空气老化试验前后质量性能的变化规律,探讨热空气老化试验对该材质消防水带爆破压力、附着强度及耐磨质量性能的影响。经试验:该材质消防水带的爆破压力值在168 h热空气老化试验前后变化不大;附着强度及耐磨性能在经过热空气老试验后,其数值均有一定程度的下降。
The influence of hot air aging test on the bursting pressure,adhesion strength and wear resistance of fire hose made of polyester filament/polyester filament-polyurethane material was investigated by studying the change law of the fire hose quality before and after hot air aging test.The test results showed that after 168 h hot air aging test the bursting pressure of the fire hose had little change,and the adhesion strength and wear resistance of the fire hose were weaken in varying degrees.
