本文研究了矿物基透明空气净化涂料的性能。该光催化涂料的空气污染物去除效率首先按照 ISO 22197-1 程序在实验室条件下测定。随后，采用新的监测方案，通过为期20个月的室外监测确定了其在实际条件下的空气污染物去除效率。持续监测天气状况，包括温度、风量、湿度、降水量和氮氧化物浓度。分析了光催化涂料的效率。讨论了环境参数对空气污染物去除效率和长期性能的影响。结果表明，这种新型涂料具有出色的空气净化效率，但环境参数对其长期性能显示出巨大影响。此外，这项研究还证实了所提出的空气净化性能监测方案的稳健性。
This paper studies the performance of a mineral-based transparent air purifying paint. The air pollutants removal efficiency of this photocatalytic paint was first determined following the ISO 22197-1 procedure under laboratory conditions. Subsequently, its air pollutants removal efficiency under realistic conditions was determined by outdoor monitoring with a duration of 20 months, applying a new monitoring protocol. The weather conditions, including temperature, wind flow, humidity, precipitation, and NOxconcentration were continuously monitored. The efficiency of the photocatalytic paint was analyzed. The influence of the environmental parameters on the air pollutant removal efficiency as well as long term performance was discussed. The results show the excellent air purifying efficiency of this new paint, nevertheless the environmental parameters show dramatic effects on its long term performance. Furthermore, this study also confirmed the robustness of the proposed air purification performance monitoring protocol.
