【摘要】 采用正交实验分析法研究了负载TiO2/ACF的非织造布净化甲醛的性能,选择TiO2量、ACF量和光照强度三个因素、三个水平进行相关实验。结果表明,低水平TiO2/ACF负载量净化高浓度甲醛时,ACF量为最大影响因素,光照强度和TiO2量的影响次之;A3B3C2(ACF 3.6 g/m2,TiO22.6 g/m2,光照强度20μW/cm2)为最佳方案,其净化率达79.2%,净化效力为50.9μg/g。更多还原

【Abstract】 The properties on purifying indoor formaldehyde of the nonwovens supporting TiO₂/ACF were studied in this paper according to the orthogonal test method.The quantity of TiO₂,the quantity of ACF and the illumination of UV-ray were chosen as the operation parameters to optimize the experiment.The results showed that under the experimental conditions studied,the most important factor was found to be the quantity of ACF,less important was illumination,then was the quantity of TiO₂,and A₃B₃C₂（ACF 3.6 g/m²,TiO₂ 2.6 g/m²,illumination of UV-ray 20 μW/cm²） was the optimum,its purifying rate was 79.2%,the effect of purification was 50.9 μg/g.更多还原
