| 摘 要： | 针对我国被动式空气净化产品净化效果测试方法标准在实际应用方面的弊端,研究采用具有自主知识产权的国产14 m3大型环境舱对纳米光催化涂料进行了单舱净化效果测试.测试方法依据QB/T 2761-2006,测试时长8 h,测试内容包括环境舱背景值、1 mL甲醛在舱内的自然衰减、紫外光降解以及纳米材料降解四部分内容.测试结果表明:与舱内甲醛自然衰减以及紫外光降解作比较,所试纳米光催化涂料对甲醛降解效果显著,甲醛的去除率最高可达67.7%.实验通过舱内换气、舱内表面清洁以及设置重复实验等方式实现了净化产品净化效果的单舱测试;同时建议相关标准补充短时净化效果测试,谨防测试结论有失偏颇.
