精细陶瓷（先进陶瓷 先进技术陶瓷） 室内照明环境下半导体光催化材料空气净化性能的试验方法 第4部分：甲醛的去除

[中文适用范围]： 本文件规定了一种测试方法，用于测定含有光催化剂或表面具有光催化膜的材料（通常由二氧化钛或其他陶瓷材料等半导体金属氧化物制成）在室内光照条件下，通过持续暴露于模拟空气污染物中，去除甲醛的空气净化性能。本文件适用于各种材料，例如以平板、板状或片状形式存在的建筑材料，这些是各种应用中材料的基本形式。本文件还适用于蜂窝状材料，以及含有陶瓷微晶和复合材料的塑料或纸张材料。本文件不适用于粉末或颗粒状的光催化材料。该测试方法通常适用于用于空气净化的光催化材料。本方法不适用于测定光催化材料的其他性能属性，如分解水污染物、自清洁、防雾和抗菌作用。 [外文原描述]： This document specifies a test method for the determination of the air-purification performance, with regards to the removal of formaldehyde, of materials that contain a photocatalyst or have photocatalytic films on the surface, 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 illumination from indoor light. This document is applicable for use with different kinds of materials, such as construction materials in flat sheet, board or plate shape, which are the basic forms of materials for various applications. This document also applies to materials in honeycomb form, and to plastic or paper materials containing 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.
