| 摘 要： | 对现有的中温太阳光谱选择性PbS涂层制备方法加以改进,直接在预处理过的铜片上化学镀PbS。首先,考察了反应温度、反应物浓度、加碱量和反应时间等对PbS涂层太阳吸收率α的影响,得到了制备PbS涂层的优化条件;然后,在PbS涂层上涂敷TiO2作为保护层,以延缓PbS涂层的氧化,对两种涂层表面进行了XPS和SEM分析。实验结果证明,在不明显影响吸收率的情况下,TiO2/PbS涂层的耐热性能、耐腐蚀性和耐磨性能比单纯PbS涂层有明显提高,从而达到既降低发射率又延缓涂层寿命的目的。

| Abstract: | A new method of preparating PbS solar selective absorbing coating for medium temperature was presented.After pretreatment,brass is overlain with PbS by chemical plating.The absorptivity of PbS coating is affected by temperature,reaction concentration,reaction time and so on.The optimized condition of preparating PbS coating was got.The PbS coating is protected by TiO2 coating for staving oxidation.The two coatings were analyzed with XPS and SEM.The experiment showed the TiO2/PbS coating is more heat-resistant,corrosion-resistant and wearable than PbS coating without reducing the absorptance.The TiO2 coating can reduce the emittance and protect he PbS coating. |
