[0005] 铜锌合金颗粒与水接触时会产生电化学反应,使水的氧化还原电位迅速改变(从+200mv到_500mv),而不同类的细菌只能在特定的氧化还原电位中生存,通过改变水的氧化还原电位就可以有效地`制或杀死细菌。 [0005] The electrochemical reaction produces copper-zinc alloy particles contact with water, the oxidation reduction potential of water rapidly changed without the same bacteria can only survive (from + 200mv to _500mv), in particular in redox potential, by changing the oxidation-reduction potential of water can be efficiently manufactured or `kill bacteria. 同时,纳米银粒子直接进入菌体与氧代谢酶(-SH)结合,使菌体窒息而死。 Meanwhile, nanosilver particles directly into cells with oxygen metabolic enzyme (-SH) binding the cells suffocate. 通过这两种物理方法协同作用,杀菌效果强劲且杀菌范围广,杀菌时效更长且可以反复使用。 By synergistic effect of these two physically strong bactericidal effect and a wide range of sterilization, disinfection aged longer and can be used repeatedly. 因此,本合金材料为很好的物理杀菌剂。 Thus, this alloy material is excellent physical fungicides.

[0006] 本发明产品的制备方法是: [0006] The method of preparing products of the invention are:

[0007] I)将纯度为99.99%的铜和纯度为99.99%的锌各占50%的比例,进行加温、溶 [0007] I) with a purity of 99.99% purity copper and the ratio 50:50 99.99% zinc, for heating, melting
