精细陶瓷（先进陶瓷 先进技术陶瓷） - 半导体光催化材料的空气净化性能试验方法 - 第2部分:去除乙醛

[中文适用范围]： 本文件规定了测定含有光催化剂或具有光催化膜的材料的空气净化性能的测试方法，这些材料通常由半导体金属氧化物（例如二氧化钛或其他陶瓷材料）制成，通过将测试件连续暴露于紫外线 (UV-A) 照射下的模型空气污染物。 本文件旨在用于不同种类的材料，例如平板、板或板形状的建筑材料，它们是用于各种应用的材料的基本形式。 本文件还适用于结构化过滤材料，包括蜂窝状、机织和非机织织物，以及塑料或纸质材料（如果它们含有陶瓷微晶和复合材料）。 本文件不适用于粉末或颗粒状光催化材料。 该测试方法通常适用于为空气净化而生产的光催化材料。 该方法不适用于测定光催化材料的其他性能属性，即分解水污染物、自清洁、防雾和抗菌作用。 它涉及乙醛的去除。 [外文原描述]： This document specifies a test method for the determination of the air-purification performance of materials that contain a photocatalyst or have photocatalytic films, usually made from semiconducting metal oxides, such as titanium dioxide or other ceramic materials, by continuous exposure of a test piece to the model air pollutant under irradiation with ultraviolet light (UV-A). This document is intended for use with different kinds of materials, such as construction materials in flat sheet, board or plate shape, that are the basic forms of materials for various applications. This document also applies to structured filter materials including honeycomb-form, woven and non-woven fabrics, and to plastic or paper materials if they contain ceramic microcrystals and composites. This document does not apply to powder or granular photocatalytic materials. This test method is usually applicable to photocatalytic materials produced for air purification. This method is not suitable for the determination of other performance attributes of photocatalytic materials, i.e. decomposition of water contaminants, self-cleaning, antifogging and antibacterial actions. It concerns the removal of acetaldehyde.
