本文介绍了聚合物膜反射表面的加速老化的条件下，在接触清洁的聚光太阳能发电（CSP）收集器在灰尘和沙粒的存在下被发现。在这些情况下，需要使用刷子和水进行接触清洁以清洁反射表面。虽然适用于玻璃反射器，本文讨论了现有的清洁工艺的聚合物薄膜表面的光学和视觉性能的影响，然后描述了一个更良性的，但有效的接触清洁工艺的发展，用于清洁聚合物反射器。一系列的清洁刷的影响进行了讨论，有和没有水的存在下，在砂和灰尘颗粒的存在下，从选定的代表性的位置。反射率测量和目视检查表明，带有少量水的软清洁刷可以清洁聚合物膜反射表面，而不会造成表面损坏或降低镜面反射率。
This paper describes the accelerated ageing of polymer film reflecting surfaces under the conditions to be found during contact cleaning of Concentrating Solar Power (CSP) collectors in the presence of dust and sand particles. In these situations, contact cleaning using brushes and water is required to clean the reflecting surfaces. Whilst suitable for glass reflectors, this paper discusses the effects of existing cleaning processes on the optical and visual properties of polymer film surfaces, and then describes the development of a more benign but effective contact cleaning process for cleaning polymer reflectors. The effects of a range of cleaning brushes are discussed, with and without the presence of water, in the presence of sand and dust particles from selected representative locations. Reflectance measurements and visual inspection shows that a soft cleaning brush with a small amount of water can clean polymer film reflecting surfaces without inflicting surface damage or reducing specular reflectance.
