Laser cleaning processes for Roads and Maritime Services bridges

该项目旨在开发创新的激光清洗工艺，以保护悉尼海港大桥的结构完整性和标志性地位。新的激光技术提供了去除含铅油漆和清洁大桥金属结构和花岗岩塔架的机会，这是目前技术所不具备的优势。预期的结果将是新的最佳实践激光保护技术，可用于手持和自动系统，以保护世界上最具标志性的桥梁之一。这将减少维护频率和成本，恢复桥梁的美观，保留其工程意义，并为其他历史大型金属和石质文物的清理提供基线程序。

This project aims to develop innovative laser cleaning processes to conserve the structural integrity and iconic status of the Sydney Harbour Bridge. New laser technologies offer the opportunity to remove lead-based paint and clean the bridge’s metal structures and granite pylons offering advantages unavailable with current techniques. The expected outcomes will be new best-practice laser conservation techniques usable for both hand-held and automated systems to preserve one of the most iconic bridges in the world. This will reduce maintenance frequency and cost, restore the beauty of the bridge, retain its engineering significance and provide a baseline process for cleaning of other historical large scale metal and stone heritage objects.
