- 摘要:
- 通过改变镀膜材料气体流量,研究热解法在线制备TiO2薄膜性能的影响。采用SEM、EDS分析了膜层表面微观形貌、断面厚度和碱腐蚀前后膜层的化学组成,采用分光光度计分析了镀膜玻璃的光学性能和颜色指标,并配制5 mol/L的NaOH溶液对薄膜的耐碱性能进行测试。结果表明:随着气体流量增大,TiO2晶体的颗粒度逐渐增大,晶体密度和膜层厚度也随之增加。TiO2膜层对太阳光的反射率(Rs)和对可见光的反射率(Rv)均增大,反射光的强度(L*)值增加,遮阳系数减小,膜层耐碱性增强。碱腐蚀前后反射光强度与颜色综合变化量均小于标准值,符合使用要求。
- Abstract:
- By changing the gas flow rate of the coating material, the influence of pyrolysis method on the performance of online preparation of TiO2 film was studied. The surface morphology, section thickness and chemical composition of the film before and after alkali corrosion were analyzed by SEM and EDS, and the optical properties and color indexes of the coated glass were analyzed by spectrophotometer, 5 mol/L NaOH solution was prepared to test the alkali resistance of the film. The results showed that the granularity, crystal density and film thickness of TiO2 crystals increased with the increase of gas flow. The reflectivity of TiO2 film to sunlight (Rs) and visible light (Rv) both increased, the reflected light intensity L* value increased, the shading coefficient decreased, and the film alkali resistance increased. The comprehensive change of reflected light intensity and color before and after alkali corrosion is less than the standard value, which is in line with the use requirements.
