摘要
调研分析了融雪防冰关键技术。融雪剂是当前的主流解决方案,但降低成本、提高效率和循环使用是发展重点。热能融冰虽然效率高,由于不具备成本优势,仅用于部分关键工程。低冰点铺装以及橡胶弹性铺装需要解决耐久性并提高效率。自防冰铺装是未来发展趋势,不仅对环境友好,而且可长期使用。这里介绍3个具有前景的技术。借鉴超薄防滑涂层技术,低冰点与橡胶弹性铺装可以整合为低冰点弹性铺装。抗粘附涂层通过降低冰层与表面的粘结强度改善轮载破冰效率。绝热层通过抑制热传导降低冰晶的发展,阻止桥面铺装上滑动面的形成。
Investigation and analysis about key technology of de-icing and anti-icing were conducted.Deicers are the current main solution,tending to environment-friendly development.Being the current main solution,there is need for deicers to reduce costs,increase efficiency and recycle.Though ice-melting with heat cable enjoyed high efficiency,it could be suitable only for some key projects due to great costs.Low-freezing pavement as well as rubber flexible pavement needed to address the durability and increase efficiency.The automatic anti-icing pavement led the development tendency.They were not only environment-friendly but also long-term efficient.Three promising technologies were introduced here. Learned from the ultra-thin non-slip coating technology,low-freezing pavement and rubber flexible pavement could be integrated into one new technology called low-freezing flexible pavement.Through reducing the bond strength between ice and pavement surface,anti-adhesion coating could improve the efficiency of breaking ice by vehicle loads.Through obstructing the heat conduction between the surface and the bridge deck,insulated layer could depress ice development so that continuous slippery surface couldn＇t be resulted in.
