将纳米TiO2加入PVC糊中制备光催化PVC糊,研究不同种类及含量的纳米TiO2、亚甲基蓝溶液的浓度对光催化PVC糊制品光催化性能的影响。实验结果表明:含掺钨改性纳米TiO2的光催化PVC糊降解效果最明显;当纳米TiO2含量为8份时,亚甲基蓝溶液降解率最高;亚甲基蓝溶液的浓度为5 mg/L时,降解效果明显。
The photocatalytic PVC paste was prepared by adding nano-TiO2 to PVC paste to study the effects of different concentrations and concentrations of nano-TiO2 and methylene blue solution on the photocatalytic activity of PVC paste. The experimental results show that photocatalytic degradation of PVC paste containing tungsten modified nano-TiO2 is the most obvious. When the content of nano-TiO2 is 8, the degradation rate of methylene blue solution is the highest. When methylene blue solution concentration is 5 mg / L, the degradation effect is obvious .
