描述:土工布老化的原因有内因和外因两种。内因指材料本身的性质,主要有:单体的结构状态、高分子体系内部性质、添加剂等;外因指外界的环境因素,主要有太阳光、氧气、热、水分、pH值、应力、工业气体、海水、盐雾、霉菌、细菌等。影响老化的原因是多种多样的,通常各种因素共同起作用,但其中太阳光、水、氧气、热是最主要的影响因素。

土工布实验室老化试验包括光照老化、湿热老化、热风老化

目前土工布滚球体育的生产和应用快速发展,对土工布的研究很多,但关于土工布老化性能的研究相对较少。土工布作为一种工程材料,其老化性能指标直接影响工程的寿命、安全性和可靠性。因此,对土工布老化性能的研究具有很高的经济意义和战略意义。美国材料与试验协会(ASTM)对土工布的定义为:一切和地基、土壤、岩石、泥土或任何其他土建材料一起使用,并作为人造工程或系统的组成部分的纺织品。土工布和地基、土壤、岩石、泥土或其他建筑材料一起使用,利用土工布对泥土起加固、保护、排水、过滤、隔离、防渗等作用。土工布目前已经同水泥、钢材、木材一起被称为“四大建筑材料”。
