香港理工大学检测报告及简要说明

根据香港理工大学2005613提供的检测结果,门德公司量子光触媒产品在防晒性能测试过程(如3.1UPF value and rating表中所示)中,未经处理的样本防晒指数为6,几乎没有任何防晒能力;经过门德公司的产品MTQP处理后,平均防晒指数达到了179,远远超过了优秀防晒指标(达到30为合格,超过50即可认为具有优秀的防晒能力);而在对有机物颜料的降解能力测试(如表一中所示,Table1.Absorbance of all samples with time中看出, 0.5%的量子光触媒处理的布料在紫外线的照射下,对有机颜料的分解效率最高0.051,较同类产品的效率高一个数量级;在3.3 XRD图中,通过X射线衍射图谱可以看出,MTQPTiO2的例子晶型为锐钛矿型,粒子平均粒径为2纳米;由3.4扫描电镜图片可以看出,TiO2粒子大小均一,成膜效果较好。
