The invention belongs to the field of titanium dioxide application and specifically relates to a method for evaluating lightening power strength of different titanium dioxides. Against technical problems to be solved, the method for evaluating lightening power strength of the different titanium dioxides is provided. The method comprises the steps of taking to-be-evaluated titanium dioxides, mixing the titanium dioxides with black master batch and resin respectively, pulling out a material plate, performing hot pressing on the material plate, taking a sample wafer after cooling, using a powder whiteness instrument to detect each sample wafer, analyzing detection results, and obtaining a conclusion. According to the method, the strength of lightening power between the different titanium dioxides can be evaluated visually, and the basis is provided for selecting an appropriate titanium dioxide for industrial application. 本发明属于钛白粉应用检测领域，具体涉及种评价不同钛白粉消色力强弱的方法。本发明所要解决的技术问题是提供种评价不同钛白粉消色力强弱的方法，包括以下步骤：取待评价的钛白粉，分别与黑母粒和树
