微波协同纳米银对羽绒的抗菌效应研究

本文研究了微波协同纳米银对羽绒抗菌除臭的新工艺,通过控制单一变量法,确定了抗菌实验中最适宜辐射时间、羽绒与纳米材料最佳质量比、辐射温度、微波辐射功率等条件。在所确定的最适条件下,探讨了微波协同纳米银的最佳抗菌率。同时,进行了纳米银的回收实验,测定了多次回收的纳米材料的最佳抗菌率的变化规律。结果表明:纳米银的优化抗菌条件为微波时间5 min,纳米银与羽绒质量比3∶1,微波时温度50℃,微波功率300 W,最佳抗菌效果88.02%,新工艺最佳抗菌率随着纳米抗菌剂使用次数增加略有下降,至少可回收循环使用2次。

The Antibacterial Effect of Microwave-synthesized Nano Silver to Down

A new down antibacterial deodorizing process by using nano-silver synthesized with the assistance of microwave was studied. By using the method of single variable control, the optimum conditions of the antibacterial test such as with the most suitable microwave radiation time, the best mass ratio of the nano material and down, the radiation temperature, and the radiation power were studied. Meanwhile, the experiment on recycling nano-silver was done, with which the variation of the sterilization rate of the recycled materials was discovered. The results reveal the optimum antibacterial conditions: radiation time 5 min, the mass ratio between silver and down is 3:1, radiation temperature 50℃, radiation power 300 W, the best antibacterial effect is 88.02%. The best antibacterial rate fell slightly with the increasing number of use of nanometer antibacterial agent. The nano-silver can be regenerated repeatedly at least two times.
